Intrusion Detection Prevention Systems have long been part of a network administrator's arsenal of tools to protect their network and ensure malicious actors are kept at bay. With the ever-increasing threat of cybercrime, they remain an essential part of any security strategy.

What is an Intrusion Detection Prevention System?

Intrusion Detection and Prevention Systems (IDPS) play a vital role in today's digital world. As more and more businesses move their operations online, the need for effective cybersecurity solutions has never been greater. IDPS solutions help to defend against threats by leveraging signature-based detection or anomaly-based detection to monitor network traffic. If it identifies any suspicious activity that may indicate an attack, an alert is sent to the administrator. The IDPS software blocks the abnormal activity to prevent the attack from moving any further through the network. If further work is required to eliminate the threat, the blocking mechanism grants the administrators time to take action. IDPS solutions can also perform health checks to monitor the performance of hardware and security components and ensure that the infrastructure is operating correctly at all times. This all works to block attacks in real-time and protect your data and infrastructure from harm. 

Functions of IDPS solutions:

Protects infrastructure and sensitive data: The IDPS identifies and alerts network administrators of attacks hiding within actual data as it flows through the network, allowing attacks that may bypass traditional defences like firewalls to be mitigated.

Review existing user and security policies: User policies and access-related policies significantly reduce an organisation's attack surface by only providing access to critical resources to those with authorisation. The IDPS continuously monitors the network to ensure that administrators can identify blind spots within the policy frameworks. It also allows for policies to be changed and tested to ensure maximum security and efficiency.

Network resource intelligence: The IDPS solution provides a holistic view of all the traffic flowing through the networks, allowing them to keep track of network resources and perform modifications in instances of traffic overload or server under-utilisation.

Why do organisations need IDPS?

Attacks on corporate networks rose by 50% between 2020 and 2021 according to research by Check Point1.  With such a significant rise in attacks, it's clear that organisations need to enhance their existing network, especially given the increased external edge susceptibility that comes with the migration to the cloud and SaaS models. IDPS solutions help to secure your network and thwart attacks that traditional network security tools typically miss. As an additional benefit, implementing an IDPS solution can also help organisations to satisfy compliance regulations regarding privacy and security, meaning you can avoid the hefty fines that result from non-compliance.
