How does Snort intrusion detection work?
The intrusion detection mode operates by applying threat intelligence policies to the data it collects, and Snort has predefined rules available on their website, where you can also download policies generated by the Snort user community. You can also create your own policies or tweak the ones Snort provides. These include both anomaly- and signature-based policies, making the application’s scope fairly broad and inclusive. 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.
How do remote access Trojans evade live data analysis?
One way in which Remote Access Trojans can evade the live data analysis NIDSs provide is by dividing the command messaging sent through the malware across multiple data packets. NIDSs like Zeek, which focus more on application layers, are better able to detect split command messaging by running analyses across multiple data packets. This is one advantage Zeek has over Snort.
What is APT in computer security?
The practice of stealthy, ongoing hacking seeking to accumulate data over time, as opposed to causing damage to information or systems, is known as an advanced persistent threat (APT ).

Can antivirus be used to get rid of a RAT?
Antivirus systems don’t do very well against RATs. Often the infection of a computer or network goes undetected for years. The obfuscation methods used by parallel programs to cloak the RAT procedures make them very difficult to spot.

Sometimes, the only solution to rid your computer of a RAT is to wipe out all of your software and reinstall the operating system.
