Context
IDS is an important part of an organisation’s network security architecture as it identifies and alerts the SOC to threats that it may have missed, which traditional firewalls do not have. Although all intrusion detection systems fulfill the same purpose, they work in slightly different ways. Altogether, there are five IDS types. An intrusion detection system (IDS) is a technology solution that monitors inbound and outbound traffic in your network for suspicious activity and policy breaches. As the name suggests, the primary purpose of an IDS is to detect and prevent intrusions within your IT infrastructure, and then alert the relevant people. These solutions can be either hardware devices or software applications.

Pending intelligence enrichment.
Analysis
Typically, an IDS will be part of a larger security information and event management (SIEM) system. When implemented as part of a holistic system, your IDS is your first line of defense. It works to proactively detect unusual behavior and cut down your mean time to detect. Ultimately, the earlier you recognise an attempted or successful intrusion, the sooner you can take action and secure your network.

To use NIDS, you typically need to install them on a piece of hardware in your network infrastructure. After installation, your NIDS will sample every packet (collection of data) that passes through it.
Key Points
- An intrusion detection system (IDS) is a technology solution that monitors inbound and outbound traffic in your network for suspicious activity and policy breaches.
- IDS is the first line of defense of network systems, which can proactively detect abnormal behavior and reduce the average detection time.
