Rise in Residential IP Providers

If you’re looking for an online, potential boom market then providing residential IP addresses could be the one you’re looking for.   A few years this simply didn’t exist and indeed most people (even IT professionals) probably couldn’t tell you what a residential IP address is and what you might need one for.

In the past it wasn’t actually that important, after all as long as you had an IP address then that’s all you needed.  Where it came from, what it was had no real importance as long as the address was valid and you could go online with it.  However this has pretty much changed, the IP address is taking on much more of a significance often in ways that are invisible to the end user.

Residential IP Providers

Consider that the vast majority of websites now will record your IP address in some way.  Everything from the huge international web presence to the two page geeky blog from your favorite online author.   Some will have installed complex systems to do this but more commonly it will be available through Google Webmaster or Analytic tools.   Potentially any web site can glean lots of information about you the very moment you visit the site.

This might be disconcerting to some, who probably still think that there’s a default level of privacy available online as long as you don’t start filling in forms or posting under your real name.  The reality is that there’s virtually none, unless you take some concerted effort there’s no privacy at all.  Your IP address is the key to your location, your identity and the link that allows webmasters to make all sorts of assumptions and decisions about you.

One of the most important factors that people are beginning to look at is the classification of the IP address.  For the home user who’s logging in from a connection to an internet service provider then that’s almost certainly going to be classified as a ‘home or residential’ user.   Believe it or not that’s a very powerful and important indicator for many websites – it marks you as being a potential customer.

Look at this video about using private proxies for Instagram, and you’ll get an idea of why many people value these IP addresses so much.

A residential IP address is a normal user who is probably accessing their website from home. As opposed to a user from a commercial address who could be at work or worse using a VPN or proxy to hide their true identity. What’s more this ‘residential address’ can also be located much more easily to a specific location. Imagine how important it is to an e-commerce website that they can determine that a visitor is a normal home user from the US or Europe. Indeed many e-commerce websites are only really interested in specific users, i.e. those who are potential customer as opposed to informational websites which have a much broader brief.

Why the Need for Residential IP Providers

There is obviously a temptation for the webmasters to focus on the people that who will potentially buy from them. After all a local store in downtown Chicago is going to prize residential addresses located in the Chicago area. Whereas visitors from commercial addresses or those located on the other side of the world are much less likely to become paying customers. There are many options the web site can take even with this fairly basic pieces of information – route them through to special areas, make special offers and so on. Indeed many web sites will use it to filter out potentially ‘bad traffic’ – e.g fraudulent transactions are much likely to come from a remote IP address or one diverted from a commercial data center through a proxy.

It’s following this logic that some companies have used this to help block entire sections of IP addresses based on location and classification. It’s most common in the entertainment industry where movies and shows are often licensed on a ‘per country’ basis. For example you can’t watch the BBC online unless you have a British IP address and you can’t access Hulu without an American IP address and so on. The country based restrictions are extremely common and are usually referred to as geo-targeting. People are generally able to bypass these restrictions and blocks fairly easily by using VPNs and proxies with servers based in the required countries.

Netflix however has introduced a very restrictive filter which blocks many of these servers. It’s not enough to have an IP address based in a specific country, you also have to have am address which is classified as ‘residential’ too. A normal VPN or proxy won’t work anymore as these have addresses usually allocated from commercial datacentres. There’s an interesting article about the concept here – Why You Need a VPN with Residential IP for Netflix, which explains what the media giant has done. For many VPN companies this meant the end of selling to potential Netflix users simply because the required addresses are so difficult to obtain.

You can still  get access to Netflix and indeed there are some companies who offer residential IPs with proxy servers and even a residential VPN.   However there’s not many of them and you should check carefully especially if you need to access a service like Netflix which only works with them.   Other companies also restrict access based on the classification – for example many social media sites like Instagram and Facebook check the origin of IP addresses.   As such many internet marketers or online businesses invest in static residential proxies in order to operate multiple accounts for marketing purposes.

You can buy residential proxies yet remember they can be expensive simply because the IP addresses are very difficult to obtain.   Where you buy them from very much depends on what purpose they are needed for.   If you’re looking to access social media or e-commerce sites then you should look for specific location – i.e to buy multiple items from the Adidas web store the best residential proxies would be those based in the US.  You’d also need many more addresses if you’re operating multiple accounts or making lots of purchases,

For accessing resources like Netflix all you need is an address based in the US, there are a couple of VPN solutions which have a selection of residential US proxies.  These can  be used to access the US version of Netflix – here’s the best options and you can test it for 14 day for free.

If you’re looking for cheap residential proxies for building Instagram accounts or building a Sneaker business then you’ll need a lot more.  The following is one of the few residential IP providers who actually own the servers that their addresses sit on.

Wireless Security Initial Concepts

Wireless security is an important part of your wireless network Without even getting Wireless Security into wired Wired Equivalent Privacy (WEP) there are certain things you can do to make your network secure and shut down the easy avenue for the hacker attacks.

An acronym for Wired Equivalent Privacy, WEP is an encryption scheme used to protect your wireless data communications.

WEP uses a combination of 40-bit keys to provide access control to your network and encryption security for every data transmission. To decode a data transmission, each wireless client on the network must use an identical 64 or 128-bit key.

Securing Wireless Networks

Ever since 2001, the use of wireless networks has exploded both in home and corporate environments. By 2006, more than 80 millions wireless local area network (WLAN) nodes should be in the hands of residential and business users combined.

Securing WLANs has been a concern almost since their inception and while much progress has been made with the introduction of WEP and WPA, both have been shown to have their own weaknesses or implementation issues.

While 802.11i is said to improve upon WEP and WPA, it is not yet commercially available and it may prove over time to have its own weaknesses as well.

There are wireless security steps that network administrators and home users alike may take to augment the security of their wireless networks, and discussing some of these steps is the purpose of this site.

None of these steps is intended as a replacement to WEP or WPA, but rather as a complement. Many of these steps do not apply to public hot spots, however, as it is generally the intent of the spot’s owner or operator to make access as easy and convenient as possible.  After all we use our networks for an increasing amount of our lives from entertainment to household and financial management.

Just have a look at this video which demonstrates how an ex-pat has turned their wireless network into a home entertainment portal. Although the channels listed are not accessible outside the uK by relaying through a third party server you can hide your location. It’s doesn’t always work but there are solutions you can see – Netflix America in UK. It’s an example why a fast, secure wireless network has become something of a necessity in the modern world.

Please remember that computer security is a complex issue and it would take volumes just to explain all of the ins and outs, but if you take some precaution to secure your wireless home network, you’ll have a basic understanding of this technology and a excellent start.

Quick Tip: All wireless devices must use the same WEP key!

Adapters and access point and other equipment all come with a default password and other settings – You should quickly change these values. Leaving these default values unchanged, just invites trouble, remember this is your private network, but the airwaves are public and the door is open to anyone that’s up to no good.

The most important values to change are the SSID, make sure this setting is the same for all devices in your wireless network.
A few things you can do to make your SSID more secure

  • Make it unique
  • Change it regularly
  • Disable SSID Broadcast

The SSID (Short for service set identifier) also referred to as a network name because essentially it is a name that identifies a wireless network.

Is the unique name shared among all devices in a wireless network. The SSID must be identical for all devices in the wireless network. It is case-sensitive and must not exceed 32 alphanumeric characters, which may be any keyboard character.

Quick Tip: It is important to note, however, that using the manufacturer’s default SSID, makes it easier for hackers or individuals to identify the access point’s manufacturer and look for specific weaknesses that may be used to gain unauthorized access or deny others access.

Make sure this setting is the same for all devices in your wireless network to insure Wireless security, I recommend that you change the default SSID to a unique name of your choice.

Disabling SSID broadcasting can be a useful security feature. However, when SSID broadcasting is disabled, Wireless site survey tools such as Windows XP’s Zero Configuration utility will not function.

It is best to disable the SSID broadcast until you have configured all of your wireless network clients.

Confused About Wireless Speeds – Standards Archive

Confused about wireless speeds, on your wireless home computer let me explain. All of the important standards are know by Wi-Fi the standards are themselves maintained by a association called Wireless Ethernet Compatibility Alliance (WECA) interoperability among the various products is a good thing.

One of the first standard to hit the market and still the most popular is called 802.11b with a rated speed of 11 Mbps – mega bits per second A standard for 802.11a, it is rated at 54Mbps – 25 Mbps – when .11b is not present and yes, “b” came before “a”

The newest product on the block with an increase in wireless speed 802.11g which is rated at 54Mbp unless you install a 802.11b card (11Mbps) , then the speed drops to the slowest device 802.11b, but they are compatible with 802.11b network interface (NIC) cards.

They should also have no problems or issues with using standard protocols such as TCP/IP which has a reliable connection and delivery protocol.  You can use them on servers and multihomed devices such as rotating proxies

Because of backward compatibility, older and slower 802.11b radio cards can interface directly with an 802.11g access point and vice versa at 11Mbps or lower wireless speeds , depending upon the range.

Quick Tip: The wireless speed gold standard is*802.11g – – the newest, fastest and most powerful kid on the block 802.11 radio technology that broadens bandwidths to 54 Mbps within the 2.4 GHz band.

In other words the two standards work together fine. But if I where installing a new wireless network or adding new wireless pc’s I would use the *802.11g for all of my computers.

We all like speed and no matter how fast we can go, on line or off , we still want to do it faster. When I moved my ISP account from the basic dial up modem (56Kbs) and replaced it with Cable I was one happy computer guy.  Let’s be honest those days are long gone and little basic modems wouldn’t keep up with even a very basic static web site now.

Most people now expect to be able to stream directly irrespective of which device they’re on.  How many of us have sat in a cafe or on a bus streaming HD quality video to the small phone in our hand, this takes a serious amount of bandwidth even if you have access to a 4G network.  I know for a fact that many people on my early morning train sit and watch the BBC on a VPN (we’re outside UK) using the wireless access point provided on the train.

Quick Tip: Troubleshooting cabling performance If you’re experiencing connection problems- check the following

So as far as wireless speed and wired networks are concerned…

    • Look for sources of interference, such as power outlets, fluorescent lights, power supplies, and coiled or extra-long cables.
    • Make sure all cable connections are secure. Check the link light on the network card – Nic – the devices you are connecting with each cable.
    • Make sure you have used the correct type of cables, either straight-through or crossover. Check hardware setup instructions to verify which cable you might need.
    • Be sure that you have not used a telephone cable in an Ethernet cable port.

The speed chain of command goes like this…

  • Fiber optic cable Uses light 186,000 MilesPsec, that’s fast The speed of light depends on the material that the light moves through – for example: light moves slower in water – glass and through the atmosphere than in a vacuum
  • Coaxial cable uses shielding to keep the signal focused and RG-6 & Cat. 5E 350MHz Dual Cableuses shielding to keep the signal focusedl reduces interference
  • Twisted pair Most commonly used in wired networks – UTP Cat 5e twists the pairs around each other to reduce interference and reinforce the signal

Sneaker Proxies and Servers

Many people spend literally thousands of dollars a month on using proxies, a fact that surprises many.  After all if you do a quick google search you’ll find lots of lists of free proxies all over the place.  Many are listed as being super secure and elite, so why on earth do people spend lots of money on them.

Well firstly, it’s important to remember that anyone who has the vaguest clue about online privacy, anonymity and the risks of cyber crime would never go anywhere near a free proxy server.  At best there badly configured proxies accidentally left open by some overworked networked admin somewhere, which means that you’re potentially stealing bandwidth if you use them.  At worst, and it’s an increasingly likely scenario the proxy has been left open on purpose in order to steal user credentials like emails, accounts and passwords.  It’s not much of a choice really, so you’d be advised to stay well clear of them.

sneaker proxies and servers

So there is a big market for safe and legitimate proxies for a variety of uses and one of the most popular is buying sneakers from online web retailers.  You see all the big retailers of sneakers (trainers in parts of Europe) release limited edition versions of their sneakers which are very much in demand.  You can try and buy them online but it’s very difficult to do and you’d have to be very quick and luck to even grab as single pair.

Obviously because they’re scarce and valuable then some people want to get lots of these – there’s an obvious profit opportunity there even if you don’t want to wear them.   So how do people get to buy loads of these sneakers online from palces like Supreme, Footlocker and Nike well they basically use software.

There are lots of automated tools and bots which you can configure to attempt to buy these sneakers when they become available.  If you get the right set up you can buy loads of these for whatever purpose you like.  The software acts like a human purchaser but with infinite patience repeatedly trying to buy the specified sneakers until they are successful. Lots of people buy up loads of these and indeed run successful businesses simply reselling these shoes at inflated prices.

TO maximise their chances they install the software programs on high availability servers with lots of bandwidth.  These can be programmed remotely to leap into action as soon as a new release becomes available.

The issue is that obviously the retailers don’t like this and try and block access to all automated efforts to buy the sneakers.  They look for things like multiple connections from the same IP addresses and ban these instantly. Which means even if you have your own server if it tries to often to buy the sneakers then it will get banned and the server and software will be unusable.

The solution is to add another layer of protection by utilizing sneaker proxies to hide your location and allow the software or Bot to rotate it’s identity in order to keep running.  It’s not difficult to do but the the essential requirement is that these are sneaker proxies with a special configuration.

The first important component which you’ll never get with free proxies is to ensure it has lots of residential IP addresses.  These are actually quite hard to get because these addresses are only normally handed out by ISPs to home users.  Most online retailers know that people try to hide their locations and often block all non-residential IP addresses automatically. Normal commercial VPN and proxies will have commercial IP addresses so won’t work in this situation.

This is what makes sneaker proxies so special, they should definitely have residential IP addresses which makes them pretty much undetectable from normal home users.  Unfortunately it’s also what makes them so expensive as obtaining, supporting and running these sorts of residential proxies is pretty costly.

There are a few companies around who have managed to obtain and specialize in residential IP proxies but there aren’t many.  In our opinion the best and most trusted supplier is a company called Storm Proxies which you can find in the link below.

Advanced Residential Proxies – Backconnect Rotating IPs

One of the earliest uses of proxy servers were to add some control over access and bandwidth to the internet from large corporate networks.  Instead of having thousands of individual computers accessing the same resources individually, a proxy can request, cache and forward the same information.  Firstly this helps reduce network traffic but more importantly allows network administrators to control and check both incoming and outgoing traffic in a single spot.

This is of course, not their only use and nowadays you can find proxies all over the place in all sorts of configurations.  The proxy server has found a new lease of life as an effective way of hiding your location and staying anonymous online.  In this article we are going to talk about a specialised configuration now commonly used for supporting automated tools and bots that people use online.

It’s easy to hide behind a single proxy to complete a single task,  however if you want to use software which performs multiple tasks then it becomes a little more complicated.  The main issue is that if a proxy is detected it can be blocked or filtered really easily, adding it’s IP addresses to a black list effectively make that proxy useless with regards  that site.

You may have come across this message in some form when using Google for instance –

Residential Proxies

it’s simply a message triggered when Google receives too many requests from a single IP address.  You can actually cause it to happen manually just by searching too quickly but obviously any software will trigger it much more easily.  So for example, research tools which send multiple requests to search engines becoming completely useless in this situation.

This is a problem suffered by all sorts of tools which need to process multiple connections to specific websites.  Things like SEO tools, automated posters, Sneaker and Twitter bots and hundreds of other automated tools that people use online to make money online.  None of them will work properly without using a significant number of proxies to support these requests.

Using Residential Proxies with Rotating IPs for Automated Tools

There are several important things to remember about using proxies in this way, including the type of IP addresses that are assigned to them. There are two major classifications of available IP addresses, commercial and residential.

  • Commercial IP Addresses – are assigned to private companies and datacentres.
  • Residential IP Addresses – are assigned to individuals and home users usually through their ISP (Internet Service Providers)

By far the most valuable are residential IP addresses simply because commercial addresses are mostly detected and blocked automatically.  Most commercial sites want to allow ordinary users, who will almost always originate from a residential IP address. Unfortunately most commonly available addresses are commercial as they usually are assigned to servers in datacentres.

If you sign up for a web site, hire a dedicated server or even just subscribe to a VPN service – all the IP addresses will be classified as commercial ones.   These addresses are actually very simple to get, however the home user addresses needed for dedicated residential proxies are much, much harder to obtain.  If you try and search you’ll find there are not many residential IP providers online.  The primary source of these addresses is ISPs however these are only allocated to individuals at specific locations.  It’s impossible to simply buy a range of residential IP addresses and assign them to some high powered servers stored in a datacentre unfortunately.   They can be obtained but the process requires contacts, expertise and lots of hardware to support them.

Private residential proxies and their addresses are therefore extremely valuable and it’s vital that they do not become banned or blocked from overuse.  Although the classification of these addresses won’t cause them to be blocked, they will be banned if too many concurrent connections originate from them.

A simple proxy server with a few residential IP addresses, isn’t going to cut it – a few automated tools running on a high bandwidth connection is going to burn through them pretty quickly.  People running all sorts of tools like Twitter Bots, Sneaker Bots and high end SEO tools need thousands of these addresses in order operate.  Even if you buy rotating proxies there’s no guarantee that this will be sufficient to support many of these tools.

Fortunately a couple of companies, and it’s no more than this have built something much more sophisticated.   These networks consist of residential IPs backconnect rotating proxies which can support thousands of IP addresses and allow all these tools and bots to run without issues.  These backconnect proxy servers aren’t single servers which simply forward and receive data like traditional proxies.   They are actually a gateway to a mesh of different machines supporting thousands of IP addresses and configurations networked together.  Every request is filtered through a different proxy and rotated through a a unique configuration with varying referrer data.

These networks allow you to point at the network and switch through thousands of IP addresses, they even switch the referrer data.  They’re obviously extremely difficult to assemble and take ongoing development however they allow thousands of users to run these high powered automated applications.  The only company who own and run their own hardware to support these residential backconnect proxies is called Storm Proxies.

You can buy residential proxies and other specialised servers on the link below.  they include a 48 money back trial as standard.

Choosing a Smart DNS vs VPN Solution

One of the problems with using VPN services is that they are difficult to use with devices other than computers. It’s fairly simple to set up a VPN on a computer, laptop or even on tablets.
However nowadays people use things like Smart TVs and media streamers such as the Roku which are difficult to configure to use VPNs even those simpler ones. This configuration issue lies at the heart of the puzzle – which is the best Smart DNS Vs VPN.

Probably the most common uses for a flash router is to act like a VPN service gateway. As you can see from a fast glance from the many sites which deal with Flash Routers, most encourage using one of the many VPN services and are frequently adding new ones. Subscribing to the VPN service is an extremely beneficial way to get access to unblocked content, so if you’re attempting to see US Netflix in Mexico or see BBC Sport on your Roku, employing a subscription service like Identity Cloaker, IPVanish or similar with your router will definitely a fantastic option.

Nevertheless, a VPN service isn’t the only way to unblock popular streaming video & music content. While utilizing a VPN support with your router can permit you to unblock content on devices such as Roku and Apple Television that may Usually not be flashed for VPN usage, you will find other services that could be utilized. The most outstanding is the, easy Smart DNS. Should I Be Using A VPN service or a Smart DNS Router Setup? Smart DNS is a protocol which may be utilized to re route traffic required for determining your geographical location.

Nevertheless, unlike a VPN, Smart DNS doesn’t provide encryption or conceal your IP address. The VPN service creates a tube which change or mask your IP to do it look you’re accessing the website from another location. Smart DNS works like more of a trick, by changing your DNS so sites think you’re qualified to access their content. The reason why SmartD NS differs enormously from a VPN with a better user rate is that it doesn’t require traveling through a remote server location. So a Smart DNS router configuration gives you a number Of the benefits a VPN service may provide without the possible disadvantage of slower speeds from heavy VPNs encryption.

Using SmartDNS is really hard to beat for ease and setup, particularly when utilizing a router upgraded with increased DD WRT firmware. When this Smart DNS router setup is complete, all system that runs throughout The FlashRouter will be using SmartDNS. So with one setup, all devices device on your network like Roku 3, AppleTV, iPads, iPhones may All access SmartDNS enabled content with no person setup. One installment and you’re ready to go!.

Primer on Protocol Verification

Depending on the environment and the purpose of a proxy then protocol verification is not always necessary. Indeed this was mostly ignored by earlier proxies and gateways as information was simply tunneled through transparently. Nowadays though there is normally some requirement to identify the protocol being transmitted through the proxy server.

Generic (circuit-level) tunneling, such as SOCKS and (SSL) tunneling, allows any protocol to be passed through the proxy server gateway. This implies that the proxy server does not necessarily understand the protocol and cannot verify what is happening at the protocol level. For example, the SSL tunneling protocol, despite its name, can tunnel /my TCP-based protocol, for example the telnet protocol.

A short-term solution to this is to allow only well-known ports to be tunneled, such as 445 for HTTPS, 563 for SNEWS, and 636 for secure LDAP. See Table 7-1 on page 135 for a list of well-known Web-related protocol ports. A longer-term solution is to be provided by proxy servers that verify the spoken protocol. More intelligence will need to be built into proxy servers to understand even protocols that are merely tunneled, not proxied. This enables proxies to notice misuse, such as exploiting the SSL tunneling to establish a telnet session.

Note that protocols that are proxied at the application level by the proxy server, such as HTTP, FTP, and Gopher, cannot be exploited as above because no direct “tunnel” is established through the proxy server. Instead, the proxy will fully re-perform the request on behalf of the client and then pass the response back.   This is important as it may be necessary for the function to be completed properly.  For example it’s common now to stream multimedia or video through  the servers and these need to function on the specific ports.  You won’t be able to stream things like the BBC TV output through this site without some sort of protocol verification taking place.

This ensures that the protocol is a legitimately allowed protocol. ‘ However, the Gopher protocol, or rather Gopher URLs, can be used to fool the proxy to make requests using other protocols by crafting special malicious URLs that convert to the language used by some other protocol.

Common Security Holes in Server Software can be read about on this blog and particularly there are Trojan horses disguised as Gopher URLs. If limiting to well-known ports is not acceptable (there are a number of servers out there running on non-standard ports), it is recommended to at least [9106/e ports that definitely should not be allowed an SSL tunnel to. Among these are ports known to be dedicated for other purposes, such as the telnet and SMTP ports (23, 25, respectively). Some proxy server software may in fact have a built-in filter for these ports and automatically disallow Gopher requests to them.

The Insider Dangers – Network Security

When most network administrators talk about network attacks most are referring to those from outside their networks.   However the reality is that those originating inside the network are not only more common but potentially much more damaging too. Internal attacks represent the vast majority of attacks on network infrastructure. They certainly can be extremely damaging and often much more challenging to find. One factor that aggravates the situation are company insiders having extensive working knowledge of security controls and considerable time to plan an assault.   There is less chance to detect those initial scanning and fingerprinting phases that outside attackers need to do.  The insiders can leverage the valid access they already have to gain additional access to systems.  There’s huge potential for both social engineering and gaining additional information and privileges from within.

There is no doubt that internal attacks are more challenging to detect than those which originate from outside the network.   It is also surprising that company’s often underpay these attacks and in many cases simply ignore them until it’s too late.

This occurs when organizations aren’t monitoring the interior as significantly as the outside. An internal assault might be the consequence of an employee progressively accumulating privileged accessibility and info over a time period of years or even decades.

The internal infrastructure may be opened up to threats from uned ucated or unsuspecting employees. Users could compromise internal security via the installation of firewall beating Peer to Peer file sharing and instant messenger applications. Some P2P applications are packed with spyware or attributes that silently allow the sharing of the whole hard drive.  There are also many threats from the many proxies and VPNs that can be installed.   Even if these VPNs are simply being used for a relatively benign activity like watching the BBC – check this post, it still represents a huge drain on available bandwidth and speed of the network.

Plus there are of course many network aware instant messengers, like AOL Instant Messenger, may be utilized to cut through any open port on a corporate firewall. Modern viruses are accompanied by many attack payloads that may open a system for the carrying. L/lost non technical customers might be unaware they’re creating a gaping security hole by going about their daily activity.

An IDS on the internal side may be utilized to discover both intentional domestic intentions and corporate policy violations. They can discover the signature of the majority of PZP tools, improper Internet use, and instant messengers. This is in addition to the anticipated intrusion monitoring capacity. These capabilities make an IDS an extremely strong security application.  You can even make sure that you keep updating the system to spot known threats more easily.  For instance if you detect a large number of attacks coming from a specific country – say Germany then configure alerts when connections are attempted from a German IP address or proxy.

The line between external and internal is increasingly obscured by corporate partner- ships as well as extranets that enable them. An attacker can jump through one part of the extranet to another, which makes the origin of an attack difficult to differentiate. As increasingly more internal security breaches are discovered, organizations will seek to enhance internal security in the future.

Orchestrating an Attack This section serves as a concise introduction to the kinds of suspicious traffic that you may encounter when using Snort. It’s by no means an effort to be all inclusive or detailed. There are many resources, both in print and on-line related to suspicious traffic analysis. In case you’ve however to develop an intensive signature analysis expertise, this section Will assist you concerning know the various genres of assault and also their associated intent. A number of phases in orchestrating an assault are generic enough that they employ to many network based attacks. If hackers are randomly looking for systems or targeting a specic firm. They follow the tried and true methodology.

Anatomy of a Denial of Service Attack

Following the first planning and reconnaissance legwork is complete, the upcoming logical step is to make use of accumulated info and assault the network. The traffic generated by strikes may take numerous different forms. Everything from the remote exploitation code into questionable normal traffic may signify an attempted assault which needs action. Denial of Service A Denial of Service assault is any attack that disrupts the use of a system in order that legitimate users can no longer access it. DoS attacks are possible on most network equipment, including routers, servers, firewalls, remote access machines, and almost every other network source.  A DOS attack may be specific to the service, like in a FTP assault, or even an entire machine.   Many times the attacks are against commercial targets or to access useful resources.  Many attacks are simply to enable installation of rogue services such as VPNs or FTP which are then used to either store data or to access resources like UK TV abroad like this.


The types of Denial of service attacks are indeed varied and operate on a wide range of targets. However they might be separated into two unique categories that relate to intrusion detection: source depletion and malicious packet strikes. Malicious packet DoS attacks work by sending abnormal visitors to the host to call the service or host to crash. Crafted packet DoS attacks happen when applications isn’t correctly coded to handle abnormal or irregular traffic. Frequently out, of spectrum traffic may cause applications to respond unexpectedly and crash. Attackers may utilize DoS attacks of crafted packages to bring down Intrusion Detection Systems too, even well developed ones like Snort. Additionally to out, of specific range traffic, malicious programs can contain payloads which create a system to crash. A packet payload is input to a service.

In any circumstance whether it’s an application or network enabled device if the input isn’t correctly checked, the application can be DoS’ed. The Microsoft FTP DOS attack demonstrates the broad selection of DoS attacks available to black hats from the wild. The initial step in the assault is to initiate a legitimate FTP link. The attacker then issues a command with a wildcard sequence. Inside the FTP Server, a function that processes wildcard sequences in FTP controls doesn’t allocate enough memory when performing pattern matching. It’s possible for the attackers command containing a wildcard order to cause the FTP service to crash. This particular attack like many including the Snort lCl/lP DoS, are just two samples of the countless thousands of potential Denial of service attacks which are possible and accessible for attackers.  The service can then be used to install malware or other code which are then used for other purposes.  As mentioned above they are often used as hosts for VPN services which are used to watch British TV overseas or other video streaming functions.

The other means to deny service is through source depletion. A source depletion DoS attack functions by flooding a service with so much regular traffic that legitimate users can’t access the service. An attacker inundating an agency with regular traffic may exhaust finite resources like bandwidth, memory, and processor cycles.A classic memory resource exhaustion attack which will bring down a device is  a SYN flood. A SYN flood takes advantage of the Transmission Control Protocol 3, way handshake. The handshake starts off with the customer sending a Transmission Control Protocol SYN pack- et. The host then sends the SYN ACK in response. The handshake is finished when the customer responds with an ACK.

In case the host doesn’t get returned by the ACK, the host sits idle and waits with a session available. Every open session consumes a certain quantity of memory. If enough three, manner handshakes are initiated, the host consumes all available memory waiting for ACKs. The traffic created from the SYN stream is normal in all other respects.

Securing Wireless Networks in Windows Server

Most companies now have some sort of wireless access implemented within their networks.  It’s easy to see why, adding a few wireless access points can be extremely useful and save expensive cabling costs.   You can add extra clients and locations to a network for literally a few pounds compared to drilling through walls, laying cables, digging up roads which can be involved in connecting traditional ethernet access for example.

Yet the security implications are often ignored, too often you can find well developed and secure networks compromised by ad-hoc wireless access points installed with little or no thought with regards to security.  Often companies simply buy off the shelf WAPs and add them to their network.  The reality is that every access point added  is an additional gateway into that network and it is essential that it conforms to the same level of security as any other device.

There are various methods to secure these points but the key is to keep to a consistent standard and ensure that these can be enforced.  One common method particularly in Windows environments is to use Group Policy Objects to enforce the wireless network settings on access points and the clients that authenticate to them.  For example you can use GPO’s to ensure that wireless network settings are configured correctly for EAP/TLS authentication which is used for most 802.1x authentication.

You should assign the GPO to computer accounts which are linked either to the domain or a specific OU configured for wireless access.  The latter is the better option as it restricts and controls access to the wireless network meaning only specifically allowed clients can use this access.   Within the group policy you can configure a specific wireless network policy by configuring settings such as the following:

  • Enforce 802.1 Authentication
  • Restrict Access to WAPs only, no ad-hoc connections allowed.
  • Ensure Windows clients can configure wireless network settings automatically
  • Provide preferred and allowed SSIDS (plus block other networks)
  • Enforce encryption – either WEP or WAP as a minimum (although stronger encryption should be used)
  • Define EAP authentication methods and levels
  • Enforce mutual authentication by validating certificates issued by RADIUS servers.

This list is a long way from being complete however it does illustrate some of the minimum configuration issues that should be covered for wireless access. Obviously requirements will vary depending on the network, applications used and the sort of access that is required from wireless connections. However most best practice guides for securing wireless access are fairly sensible. For example there is little reason for not implementing the strongest form of wireless encryption that is available. Encryption adds very little overhead and it is unlikely that there would be any issues with running remote applications or client access across them.

Even running additional layers such as a secured VPN can operate over an encrypted wireless connection. However remember that these can affect external access, even sites like the BBC block some VPN access (read article) in order to enforce their region locks. Even still external access and applications should not be allowed to control or dictate levels of security of your clients and internal networks. Further more through group policy you can enforce minimum levels of authentication, deploy certificates and even define more specific wireless settings. Any clients accessing the network through a Wifi access point would have these settings applied in order to access network resources.
