IDS vs IPS

Introduction

Intrusion detection is the act of continuously monitoring and analyzing network events for signals of potential incidents, violations, or threats to your security policy. The technique of doing intrusion detection and subsequently terminating the detected instances is known as intrusion prevention. Intrusion detection systems (IDS) & intrusion prevention systems (IPS) are security solutions, which become the core of your network to detect and prevent potential occurrences.

Intrusion Detection Systems (IDS) look for signs that match known cyberattacks in network traffic. Intrusion Prevention Systems (IPS) examine packets as well, but they can also prevent packet delivery based on the type of assault it identifies, thereby aiding in the prevention of the attack. In this article, we'll be walking through all the potential differences between the IPS vs IDS in detail.

Intrusion Prevention System (IPS)

An intrusion prevention system (IPS) is a system that detects and prevents intrusions. It tries to identify possible threats by monitoring properties of a protected host or network, and it can employ anomaly, signature, or hybrid detection methods to do so. Unlike an IDS, an IPS initiates steps to prevent or mitigate a threat. While an IPS may generate an alert, it also aids in the prevention of intrusion.

The platform checks for patterns that signal vulnerabilities or exploitation efforts using signature-based detection.

These systems also include automated actions such as traffic source address blocking, malicious packet dropping, and user notifications. An IPS solution is, at its core, not merely a diagnostic tool for detecting network security risks, but also a platform that can respond to them.

Classification of IPS

• NIPS: A network-based IPS analyzes and secures your network's traffic.
• WIPS: In a wireless IPS, keep an eye on what's going on in a wireless network and defend against an assault that originates there.
• NBA: A network behavior analysis look for assaults on your network that include unusual traffic.
• HIPS: Events that occur on a specific host are being scanned in a host-based IPS.

Intrusion Detection System (IDS)

An intrusion detection system (IDS) is a passive monitoring system that detects cybersecurity threats to a company. If a suspected intrusion is discovered, the IDS sends out an alert to security staff, instructing them to examine the situation and take appropriate action.

There are several ways to classify an IDS solution. It is indeed the location of its deployment. An IDS can be implemented on a single server to monitor network traffic, ongoing processes, logs, and so on, or it can be deployed at the network level to identify risks across the entire network.

A tradeoff exists between the depth of transparency and the range and context that a system receives when deciding between a network-based intrusion detection system (NIDS) and a host-based intrusion detection system (HIDS).

IDS solutions are also classed according to how they detect possible threats. To identify known threats, a signature-based IDS consults a library of signatures. An anomaly-based IDS creates a model of the protected system's "typical" behavior and alerts on any deviations. To identify potential dangers, a hybrid system employs both methods.

Classification of IDS

• NIDS: A network intrusion detection system chooses a location on your network and views all traffic on all machines from that location.
• HIDS: A host-based intrusion detection system monitors traffic to and from isolated devices on your network, and ignores traffic from other devices.
• PIDS: Whereas a protocol-based intrusion detection system puts a firewall between a device and a server, and watches all traffic between them.
• APIDS: Here, an application protocol-based IDS place protection within a set of servers and monitor how they communicate.
• Hybrid: The work done in a hybrid IDS is to integrate some of the tactics outlined above to set up a system with all the customized needs.
