How do I find an intruder in my network?
An IDS is either a hardware device or software application that uses known intrusion signatures to detect and analyze both inbound and outbound network traffic for abnormal activities. This is done through: System file comparisons against malware signatures. Scanning processes that detect signs of harmful patterns.
Is Zeek anomaly based?

Is Snort signature based or anomaly based?
Snort. Snort is an open source, signature-based, Network Intrusion Detection System (NIDS), capable of performing real-time traffic analysis as well as packet logging on IP-based networks.
How do man in the middle attacks work?
A man-in-the-middle attack is a type of eavesdropping attack, where attackers interrupt an existing conversation or data transfer. After inserting themselves in the “middle” of the transfer, the attackers pretend to be both legitimate participants.

Is Zeek signature based?
Zeek is not a classic signature-based intrusion detection system (IDS); while it supports such standard functionality as well, Zeek’s scripting language facilitates a much broader spectrum of very different approaches to finding malicious activity.
How effective is snort?
With the ability to use rulesets to monitor IP packets, Snort is an excellent choice for administrators responsible for security on small- to medium-sized networks. The ease with which Snort may be deployed on a network allows for the quick installation of a flexible and very cost-effective IDS.
Does Cisco use Snort?
