Logging can be the most useful tool in your security arsenal, but it’s something we all tend to overlook and not assign appropriate resources to, as it can use up hard drive storage. Proper logs can provide evidence as to how an incident occurred and what the attacker did.
Too often we don’t keep logs long enough. FireEye indicated that the median dwell time for attackers who use ransomware as their attack tool of choice is 72.75 days. A report on a ransomware attack from last year showed that the attacker lurked in the network for eight weeks before detonating the malware.
