Inside the secure network, an IDS/IDPS detects suspicious activity to and from hosts and within traffic itself, taking proactive measures to log and block attacks. Firewalls control incoming and outgoing traffic based on rules and policies, acting as a barrier between secure and untrusted networks.

It's no longer enough to rely on a simple security system and antivirus software that can protect against known attacks at the application layer.Ī variety of tools and methodologies exist, however two common elements used to secure enterprise network configurations are the firewall and intrusion detection and intrusion prevention systems (IDS/IDPS). Organizations need to secure their networks with a combination of technologies and detection methods designed to combat multiple attack vectors, intrusion and compromise methods available to cyber criminals today. Why are NIDS Needed?ĭue to the sophistication of cyber threats and data breaches, implementing and maintaining network security, data security and information security requires a defense in depth approach. Any malicious activity or violation is typically reported either to an administrator or collected centrally using a security information and event management (SIEM) system. NIDS monitor network traffic and detect malicious activity by identifying suspicious patterns in incoming packets.
Network intrusion detection systems (NIDS) attempt to detect cyber attacks, malware, denial of service (DoS) attacks or port scans on a computer network or a computer itself.
