Palo Alto Networks Security Engineer Interview Questions

I would review the command line, parent process, user context, network behavior, and any related files or persistence mechanisms. Then I would check whether the script matches normal administrative use or looks like an attacker technique. The strength of the answer is in tying script execution to the broader attack chain.

I would reduce unnecessary trust between systems, restrict administrative paths, and monitor for unusual remote execution or authentication patterns. Then I would use segmentation and identity controls to make stolen credentials less useful. Preventing lateral movement is mostly about limiting what a compromised host can reach.

I would look at how well it reduces risk, how much noise it creates, how easy it is to operate, and whether it fits the existing environment. A control is only good if it is effective and maintainable in production. The best answer balances protection with operational reality.

I would make sure identity data is accurate, current, and securely collected so policy decisions reflect the right user. Then I would verify that mappings are consistent across systems and do not drift in a way that breaks access control. Identity-based policy is only as good as the quality of the identity signal.

I would identify the source host, the destination, the timing, and the process responsible for the traffic. Then I would determine whether it looks like normal application behavior, a misconfiguration, or a possible compromise. The main goal is to decide quickly whether the traffic is expected or dangerous.
