Snort’s base policies can flag several potential security threats, including OS fingerprinting, SMB probes, and stealth port scanning.
What is the best way to detect malware?
The best option, especially for larger organizations, is to employ an intrusion detection system, which can be host-based or network-based. Host-based intrusion detection systems (HIDSs), which are installed on a specific device, monitor log files and application data for signs of malicious activity; network-based intrusion detection systems (NIDSs), on the other hand, track network traffic in real time, on the lookout for suspicious behavior. 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.
