An insider threat can feel a bit like the plot twist in a spy thriller. You know, the moment when the protagonist realises the enemy is not just at the gates but has been inside the house the whole time. Suddenly, all those polite conversations by the water cooler take on a sinister meaning. So, what do you do when your very own corporate narrative takes a turn for the dramatic?
Identifying the Mole
Recognising that you have an insider threat is akin to Bruce Willis discovering the baddies in Nakatomi Plaza. It starts with anomalies – those little blips on the radar that don’t quite fit. Perhaps it’s an unusual after-hours access or data transmissions that scream “I’m up to no good!” It’s all about the IoCs (Indicators of Compromise) and your ability to pick up on them quicker than Sherlock Holmes on a good day.
Many times though, it’s not a flashing red icon on the screen which will let you know that someone’s intentions may not be completely pure – but rather from colleagues. While technology is great, nothing picks out an insider faster than a vigilant co-worker. Red flags from co-workers can include, but not be limited to people working odd hours, having substance abuse, or gambling addictions, asking invasive questions about data which doesn’t involve them, or frequently contradicting themselves about their personal lives and backgrounds.
While none of these things in isolation necessarily mean your co-worker is an aspiring Dr Evil, small things can add up.
Containment: The First Line of Defence
Once you’ve identified your very own Benedict Arnold, the next course of action is containment. Think Elliot Ness in “The Untouchables” – quick, decisive, and utterly cool under pressure. You’ll want to limit their access faster than you can say, “Houston, we have a problem.” This includes revoking access rights, isolating machines from the network, and going through the logs to double and triple check what activities the insider has been up to. It’s not just about stopping the immediate threat; it’s about ensuring the security breach doesn’t spread like wildfire.
Eradicate the Threat
Eradication isn’t just about getting rid of the threat; it’s about doing it with the efficiency of John Wick at an assassin’s convention. Whether it involves disciplinary actions, legal steps, or simply escorting the individual out of the building with their belongings in a box, or maybe in handcuffs, it needs to be executed quickly and with precision.
Recovery and Reflection
After the storm has passed it’s time to look into what went wrong, what went well, and where improvements could be made. A thorough audit is needed and defences rebuilt to be stronger than before.
The Sequel No One Wants but Everyone Needs
Insider threats aren’t a one-off scenario, and they don’t just impact one organisation. By the looks of things, they don’t seem to be slowing down either. So prevention needs to be a priority. This involves training, vigilance, and creating a strong culture where security is taken seriously by everyone.
Awareness needs to be built as well as regular drills to keep everyone up to date on the latest threats.
Finally, it’s important to not keep the event and learnings to yourself. Share the learnings with other organisations so that they too can better prepare themselves and hopefully not fall victim to a malicious insider.
