According to the 2019 Verizon Data Breach Investigation Report a third of all data breaches within businesses involve internal staff. That’s a lot given that our employees and colleagues are those who we know and trust. Let’s look closer at the insider threats and see how to defeat them!
An insider threat is a human security risk which comes from within an organization. The bad actors here are not your standard cybercriminals but current or former employees or contractors who compromise the safety of your data. They may do it accidentally (we call them negligent insiders – often they’re those who fall victim to social engineering attacks), but they can also do it intentionally (malicious insiders).
Both negligent and malicious insiders are highly dangerous and it’s worth taking time and effort to detect their actions before any harm is done. Insider threats can take different forms – from an organized attack on a company’s top-secret information and modification of important data to an unintentional, but harmful data leakage. They can cause huge financial and reputational damage to any organization – especially the household names!
Insider threats are difficult to spot, mainly because the insiders already know where the sensitive data is stored and have legitimate access to it. They may work on it regularly so distinguishing whether they are doing their job or taking part in potentially malicious activity is a challenge. No anti-virus for human threats.
To combat insider threats you have to employ a much stronger sensor ... PEOPLE! Training employees on signs of an insider threat will greatly increase your ability to catch possible breaches early. Once everyone is aware of the risk and has a data security mindset, they’re more vigilant and notice unusual things earlier. Here’s a list of useful tips to follow:
Partaking in thorough and engaging training is the most effective way to successfully defend against the risk that insider threats create. It will make employees aware of the risks and signs of insider threat activities, confident enough to raise the red flag when they see suspicious activity and prudent enough from becoming accidental insiders. People are your best sensors!
