This makes Security Event Manager an incredibly useful RAT detection tool, considering how APTs tend to stay under the radar over long periods of time.

The best option, especially for larger organizations, is to employ an intrusion detection system, which can be host-based or network-based.

When used together, HIDSs and NIDSs create a security information and event management (SIEM) system. SIEM is an incredibly beneficial part of a strong security regimen and can help to block software intrusions which have slipped past firewalls, antivirus software, and other security countermeasures.
