Theyre tricky because, unlike external attacks, these guys and gals already have legit access. Makes detecting and responding a whole nother ballgame. So, what does effective incident response even look like when youre talking about someone within your own organization?


First off, you cant just ignore the possibility. Pretending it wont happen isnt a strategy. You gotta have proactive measures in place. Think strong access controls – only give people the permissions they truly need. Least privilege, remember? And monitor, monitor, monitor! You dont want to be creepy about it, but you need to be looking for anomalous behavior.

Proper investigation is crucial. Gather evidence, but do it discreetly. You wouldnt want to tip off the potential insider and give em a chance to cover their tracks. Involve HR and legal early on; theyre your friends here. You dont want to accidentally violate someones rights or botch the investigation.


If the investigation confirms wrongdoing, then you act. Containment is key. Immediately revoke access, isolate affected systems, and prevent further damage. What you do next depends on the severity of the incident and your companys policies. Could be disciplinary action, could be termination, could even involve law enforcement. Its a tough call, and its not something you decide lightly.


Communication is also vital. You cant keep everyone in the dark. But be careful!

    You dont want to create panic or spread rumors. Communicate clearly and concisely, focusing on the facts and avoiding speculation. Explain what happened (without revealing sensitive details), what steps youre taking to address it, and what youre doing to prevent it from happening again.


    Finally, learn from it! An incident response isnt truly finished until youve conducted a post-incident review. What went wrong?
