What on earth is making my home network so slow! (Part 1)

networkLet's face it, we've all been there. Sitting wondering why on earth a network connection that, up until 5 minutes ago had been working just fine was now all but useless. Less tech savvy individuals may just shrug their shoulders and try again later but anybody else is left wondering why. As a reader of this blog post that fact automatically places you in the latter category. So, to the problem. Could it be that somebody else in the house has started a large download? If that's the case its the easiest to solve just by asking around but the plethora of devices that are in our houses today make the job a lot more complex. For me it was a long forgotten mobile phone owned by my son, left on charge under the bed and set to auto update its code and apps that proved the final straw and drove me to come up with a solution to this problem.

Lets look at the problem in the round first of all. Homes nowadays usually have a router which connects off to the cable company or to the telephone line. These routers allow all of the devices in the house to connect to the net whether on the wireless or the wired side of life. Its not uncommon for a home network to support 10 to 20 devices not all of which will be known about by every other member of the household. Any one of these devices has the potential to bring the network to its knees for hours at an end by starting a large download. Of course the possibility also exists that somebody else on the outside has gained access to your network and it's important that this is not overlooked.

The first step in getting a handle on the situation will be to take control of your home router and secure it so that it cannot be manipulated by anybody else. Most home routers nowadays have a small, cut-down, webserver running on board which allows a management user to access the management web page. By using this web page clients can change all of the settings on the device. The page is usually accessible by both the wired and the wireless network. If you are using a Windows machine the easiest way to establish a connection to this page is to do the following:

Untitled

  1. Click the pearl button and in the box which says "search programs and files" type cmd and press enter. This should bring up a window which looks like that shown on the right. Inside this window, type the command "ipconfig". The output should also resemble that shown on the right showing among other things, the address of the default gateway. Take a careful note of this address. (192.168.1.1 in this case)

  2. Open up a browser, type this default gateway address into the address bar and click enter. If your router is new or poorly configured you should now be looking at the control page for the device. If the device is configured properly you should now be looking at a login prompt page.

  3. Once logged in you will then be able to control the settings of the router.


This post is not written to be a guide for any specific router so I will keep any further instructions necessarily wide in scope.

The following bullets will link to posts that will be made available soon which examine the different aspects of this problem. Check back soon to see them when they become available.

  • Who is connected? Checking to understand which devices are connected to your router on WIFI and wired networks and establishing whether or not they should be.

  • What are they doing? Most routers show a basic table of transferred bandwidth as a part of their reporting. This can be used to examine the usage on your network and ascertain which devices are consuming most of the network.

  • Securing my router. As touched on previously, the router should be configured appropriately so that only those users whom you wish to have access are able to access both the network and the routers management page.

  • Customising the routers code. Home routers purchased off the shelf nowadays have woefully inadequate firmware that is frequently shown to be buggy at best and insecure at worst. Consider replacing this firmware with a fully customisable open source router such as dd-wrt or tomato.

  • Open source router management. (Wireshark and SNMP) Want to take the control of your home network to the max. Consider implementing network management, bandwidth management and device management.


I hope this post has proved informative as an intro to controlling your home network. Check back soon for further updates.

Wi-Fi security luddite? The ICO is coming for you!

The Information Commissioner's Office today published new guidance for home Wi-Fi security after a YouGov report found that 40% of home users did not understand how to manage the security settings on their networks.

The survey also found that in spite of most ISPs now setting up and installing security on Wi-Fi equipment, 16% of the people surveyed were unsure whether or not they were using a secured network, or were aware they weren't, but didn't give a toss either way.

The new guidance includes information on managing encryption settings and how to think of a secure password. Top tip? Don't use pa55w0rd.

Giving people unsolicited access to your network could reduce connection speed, cause you to exceed data caps, or allow hordes of criminals to use your network for nefarious purposes, said the ICO.

Welcoming the move, D-Link's Chris Davies pointed out that there was no excuse for being caught out.

"There is no doubt that in the past setting up security on wireless networks could be tricky," said Chris. "But this is no longer the case with most wireless products.

"Security can be set up wiin a couple of minutes with no prior technical knowledge required. We've also been working with ISPs to help them ship products to consumers with security pre-configured."

Let's just hope the ICO doesn't start fining home users for data breaches. Or maybe that would be the kick in the butt some of them need?

How to recognise security vulnerabilities in your IT systems

As IT systems continue to extend across multiple environments, IT security threats and vulnerabilities have likewise continued to evolve.

Whether from the growing insider threat of rogue and unauthorised internal sources, or from the ever increasing number of external attacks, organisations are more susceptible than ever to crippling attacks. It's almost become simply a matter of "when it will happen" rather than "if it will happen."

For IT resellers, security issues have always persisted as critical to all communications for an organisation's IT department.

However, with the increase in the levels of access to a company's network compounded by these maturing threats, it is no longer feasible to merely recognise the existence of more simplistic, perimeter threats.

Resellers must be able to provide customers with a comprehensive risk assessment of the entirety of an organisation's IT assets to their vulnerabilities--inclusive of both software and hardware.

This risk assessment must incorporate an understanding of external threats and internal vulnerabilities and how the two continue to merge to create increasingly susceptible IT environments.

At the most basic level, organisations and resellers alike must understand the different types of threats. Malware, a generic term for malicious software, such as trojan horses, worms, and viruses, is the most common form of attack that is originated by an external hacker. Malware attacks have persisted for years - from the infamous Morris worm to common spyware attacks - and they remain the easiest and most damaging tactic deployed by malicious hackers.

With enterprises extending to the cloud, and more organisations adopting SaaS-based applications, social media and other Web 2.0 tools, damaging malware attacks and viruses can now originate through simple SPAM messages and emails.

Internally, organisations are typically susceptible to threats from either authorised rogue users who abuse privileged accounts and identities to access sensitive information, or unauthorised users who use their knowledge of administrative credentials to subvert security systems. It is this type of vulnerability - unauthorised internal access - that has continued to emerge as the most volatile and disruptive.

To truly understand the risks involved with these "insider threats", organisations and resellers need to understand the root of the vulnerabilities.

Most commonly, the risks lie with the use of embedded credentials, most notably hard coded passwords, a practice employed by software developers to provide access to administrators during the development process. The practice occurs frequently since application developers tend to be more focused on the development and release cycle of the application, rather than any security concerns. While it may appear harmless at first glance, it is extremely risky as it can potentially provide unauthorised users with powerful, complete access to IT systems.

To compound the matter, by hardcoding passwords to cover embedded credentials, vendors create a problem that cannot be easily fixed nor assuaged by tools such as Privileged Identity Management systems. Once embedded into an application, the passwords cannot be removed without damaging the system. At the end of the day, the passwords provide malicious outsiders with a bulls eye target - a key vulnerability to leverage to help them gain powerful access and control on a target device, and potentially throughout the entire organisation.

One of the most well known examples is the Stuxnet virus. We've all been blown away by the design of Stuxnet, and were surprised by the pathway the virus took in targeting SCADA systems. Reflection shows that the virus used the hard coded password vulnerability to target these systems - which should serve as a lesson for all businesses.

The existence of vulnerabilities embedded within these types of systems is not necessarily new, but the emergence of new threats continues to shed light on the ease with which they can be leveraged for an attack. While malicious outsiders and insiders have focused often on the administrative credentials on typical systems like servers, databases and the like, in reality, IT organisations need to identify every asset that has a microprocessor, memory or an application/process. From copiers to scanners, these devices all have similar embedded credentials that represent significant organisational vulnerabilities.

While steps can be taken to proactively manage embedded credentials without hardcoding them in the first place - Privileged Identity Management tools can help - the onus is on the organisation, and the reseller, to ensure that a holistic view of all vulnerabilities and risks has been taken.
