How to Prevent Deliberate IT Security Threats from Within

If you’re asked to picture people who might threaten your IT network, you’ll probably conjure up images of shadowy faces sitting in front of glowing computer screens in dingy basements halfway across the world. In reality, the person who will compromise your security could be the person you just passed in the hall.

That might sound like a rather paranoid point of view, but the evidence bears it out. In fact, a study by IBM found that the majority of cyberattacks faced by businesses can be directly linked to one of their employees. This is sometimes down to negligence, but many employees act deliberately. All it takes is an unhappy employee to copy your sensitive data onto a flash drive or upload it through a third-party cloud service – just like that you’ve got a security breach on your hands.

So, how do you prevent those internal threats?

Employ Network Segmentation

Network segmentation allows you to subdivide your business network into several smaller sub-networks. Instead of giving employees access to the entire network, you’ll only provide access to one part.

Blacklist Certain Sharing Software

When an employee shares your data, they often do so by using sharing software or cloud services that allow direct uploading. You can make it more difficult for them to operate by restricting certain software and services, effectively blocking their avenues for wrongdoing.

Prevent Password Sharing

One of the reasons why malicious employees do what they do is because they think it is unlikely that they will be caught. If you allow your staff to share passwords, it’s going to be very hard to hold certain people accountable. Make sure this stops – employees will find it harder to operate without detection if there is strictly one password per team member.

Use an IT Support Service

Finally, make sure you use an external IT support team. They will be able to provide 24/7 coverage, so they’ll be likely to catch any wrongdoer before they can erase signs of their activity. Additionally, knowing that a professional provider is monitoring your system will make it dramatically less likely for a team member to try their luck in the first place.
