Defense in Depth Part II In our last blog we started talking about the different layers of security necessary to fully defend your data and business integrity. Today we will look at the human aspect of it, and network defenses. The human layer refers to the activities that your employees perform. 95% of security incidences involve human error. Ashley Schwartau of The Security Awareness Company says the two biggest mistakes a company can make are "assuming their employees know internal security policies: and "assuming their employees care enough to follow policy". Here are some ways Hackers exploit human foibles: Guessing or brute-force solving passwords Tricking employees to open compromised emails or visit compromised websites Tricking employees to divulge sensitive information For the human layer, you need to: Enforce mandatory password changes every 30 to 60 days, or after you lose an employee Train your employees on best practices every 6 months ...

In the 1930s, France built a trench network called the Maginot Line to rebuff any invasion. The philosophy was simple: if you map out all the places an enemy can attack, and lay down a lot of men and fortifications at those places, you can rebuff any attack. The problem is, you can't map every possible avenue for attack. What does this have to do with IT security? Today many business owners install an antivirus program as their Maginot Line and call it a day. However there are many ways to get into a network that circumvent antivirus software. Hackers are creating viruses faster than antivirus programs can recognise them (about 100,000 new virus types are released daily), and professional cybercriminals will often test their creations against all commercially available platforms before releasing them onto the net. Even if you had a perfect anti­virus program that could detect and stop every single threat, there are many attacks that circumvent anti­virus programs entirely. For exam...

Phishing Scams – A People Problem There are some things that only people can fix. There are many security risks to which your data is susceptible, but there is one method that remains a wonderfully effective hacking tool. That is the phishing scam. This is a legitimate looking email that asks the reader to click on a link. If clicked, the link can infect the user’s computer with malicious software that can steal passwords, logins, and other critical data. Alternatively, the email appears to be from a legitimate source, perhaps even duplicating a legitimate webpage. The distinction is that the phishing email asks the user to enter personal information, including passcodes. In either case, that is how hackers easily get into your systems. What's the best defense against this one? The single biggest defense is education. Training your people to be constantly wary of all the emails they receive. One way some firms are educating their people is by sending out their own "fake" ...

This cyberattack scheme hasn't garnered nearly as much attention as the usual "break-in-and-steal-data-to-sell-on-the-Internet version," but it can be even more debilitating. Ransomware attacks have begun appearing in the last few years and its practitioners are so polished that in few cases they even have mini­call centers to handle your payments and questions. So what is ransomware? Ransomware stops you from using your PC, files or programs. The business model is as old as the earliest kidnapping. They hold your data, software, or entire PC hostage until you pay them a ransom to get it back. What happens is that you suddenly have no access to a program or file and a screen appears announcing your files are encrypted and that you need to pay (usually in bitcoins) to regain access. There may even be a Doomsday-style clock counting down the time you have to pay or lose everything. Interestingly, one of the more common "market segments" being targeted in the US ha...

You hear on the news all of the time about big cyber attacks on large corporations, and even government agencies. The trouble with this news coverage is that is suggests a distorted view of where cyber attacks are taking place. These attacks are not solely hitting large organizations. Small firms represent a significant portion of those who face cyber attacks. Being small by no means keeps you immune. In fact, small firms can be used as conduits to larger organizations. That is likely what happened in the case of Target Corporation back in 2013 If you're a small business, then you're a target for cyber criminals. Last year, 71% of small to medium size businesses were the victims of cyber attacks. Today's concern is how you would respond to an attack. 31% of small to medium businesses do not have a plan of action for responding to IT security breaches, and 22% admit that they lack the expertise to make such a plan. A data breach is disastrous. Your response determines whethe...
