Best Intrusion Detection and Prevention Systems (IDPS) for 2022

Intrusion detection systems (IDS) and intrusion prevention systems (IPS)  – often combined as intrusion detection and prevention (IDPS)have long been a part of the network security toolbelt for detecting, tracking, and blocking threatening traffic and malware.

With the evolution of cybersecurity solutions from the early days of firewalls, these distinct capabilities merged to offer organizations both IDPS solutions. Fast-forward and security tools continue to combine features, including IDPS, into advanced solutions like next-generation firewalls (NGFW) and XDR. While IDPS comes with a growing number of products and managed services, vendors still offer standalone IDPS, allowing organizations to pick a solution that supports their other security assets and needs. Be it a physical, cloud, or virtual appliance, the next-generation intrusion prevention systems (NGIPS) of today are worth any growing enterprise’s consideration.

In this guide, we cover the industry’s leading intrusion detection and prevention systems (IDPS), what to consider when along a summary of key features to look for as you evaluate solutions.

What is an Intrusion Detection and Prevention System (IDPS)?

Intrusion Detection and Prevention Systems (IDPS) monitor network traffic, analyze it and provide remediation tactics when malicious behavior is detected. Physical, virtual, and cloud-based IDPS solutions scan for matching behavior or characteristics that indicate malicious traffic, send out alerts to pertinent administrators, and block attacks in real-time.

Having both the capabilities to detect and prevent is vital to adequate security infrastructure. Detection only identifies malicious behavior but won’t block or prevent attacks when one hits the alarms. It will solely log these alerts. Prevention systems can adjust firewall rules on the fly to block or drop malicious traffic when it is detected. Still, they do not have the robust identification capabilities of detection systems.

IDPS tools can detect malware, socially engineered attacks, and other web-based threats, including DDoS attacks. They can also provide preemptive intrusion prevention capabilities for internal threats and potentially compromised systems.

Features of IDPS Solutions

The primary functions of IDPS solutions can be broken down into four main categories:

  • Monitoring: IDPS monitors IT systems using either signature-based or anomaly-based intrusion detection to identify abnormal behavior and signature malicious activity.
  • Alerts: After identifying potential threats, IDPS software will log and send out alert notifications to Inform administrators of abnormal activity.
  • Remediation: IDPS tools provide blocking mechanisms for malicious threats, giving administrators time to take action. In some cases, IT teams may not need to take action after an attack is blocked.
  • Maintenance: Besides monitoring for abnormal behavior, IDPS tools can also monitor the performance of IT hardware and security components with health checks. This health monitoring ensures a security infrastructure is operating correctly at all times.

Intrusion Detection (IDS) vs. Intrusion Prevention (IPS)

A holistic IDPS tool requires both detection and prevention capabilities. When browsing for solutions, you will likely encounter intrusion detection systems (IDS) and intrusion prevention systems (IPS). These are standalone products and should not be confused with IDPS, which will help you avoid large holes in your security infrastructure.

Intrusion Detection System (IDS) Intrusion Prevention System (IPS)
IDS tools were built to detect malicious activity and log and send alerts. They are not capable of preventing an attack. The warnings they raise always require human intervention or an additional security system. IPS solutions respond based on predetermined criteria of types of attacks by blocking traffic and dropping malicious processes. IPS tools lead to more false positives as they have inferior detection capabilities than IDS.

IDPS solutions incorporate the strengths of both systems into one product or suite of products.

What are the Types of IDPS?

The types of IDPS are classifiable according to their protection priorities. They generally fall under two types: host-based and network-based.

Host-Based IDPS

Host-based IDPS is software deployed on the host that solely monitors traffic to connect to and from that host. It typically only protects a single, specific endpoint. In some cases, it may also scan system files stored on the host for unauthorized changes and processes running on the system.

Network-Based IDPS

Network-based IDPS, also sometimes called network intrusion detection systems (NIDS), are deployed in a place where they can monitor traffic for an entire network segment or subnet. Their functionality somewhat resembles firewalls, which can only prevent intrusions coming from outside the network and enforce access control lists (ACLs) between networks.

NIDS was built to detect and alert potential malicious internal traffic moving laterally throughout a network; this makes it an excellent tool for a zero trust security framework. The traffic gets analyzed for signs of malicious behavior based on the profiles of common types of attacks.

Intrusion Detection Methodologies

These systems identify potential threats based on built-in rules and profiles. The most common are signature-based and anomaly-based detection methodologies.

Signature-Based Intrusion Detection

Signature-based intrusion detection looks for instances of known attacks. When malicious content is identified, it is analyzed for unique features to create a fingerprint or signature for that attack. This signature could be in the form of a known identity or pattern of behavior. Signature-based systems then compare this fingerprint to a database of pre-existing signatures to identify the specific type of attack. The downside to these systems is that they must be updated regularly to recognize new and evolving types of attacks.

Anomaly-Based Intrusion Detection

Anomaly-based intrusion detection builds an initial “normal” behavior model for a specific system rather than creating fingerprints. The system will then compare all real-time behavior against the previously created standard model to identify behavioral anomalies. These instances of abnormal behavior get used in determining potential attacks and trigger alerts.

Contrasting Signature-Based vs. Anomaly-Based IDPS

There are issues with both of these systems individually. Signature-based detection has low false positives but can only detect known attacks making them vulnerable to new, evolving attack methods.

Anomaly-based detection can lead to high false positives as it alerts all anomalous behavior. But it has the potential to catch zero-day threats. Fortunately, many IDPS products combine both methodologies to complement their strengths and weaknesses.

Challenges When Managing IDPS

You may experience some challenges when it comes to IDPS software tools. Here are a few to keep top-of-mind:

  • False Positives: You will almost undoubtedly run into the problem of false-positive alerts, which can waste time and resources. Be vigilant when notified of potentially malicious behavior, but also be aware that it’s not a guarantee of an attack.
  • Staffing: Cybersecurity is so essential to modern organizations that there is a shortage of available security professionals. Before implementing an IDPS system, ensure you’ve put together a team that has the capabilities to manage it effectively.
  • Genuine Risks: Beyond just managing an IDPS, there will be cases where administrator intervention is required. An IDPS can block many attacks but not all. Ensure teams keep their knowledge up-to-date on new types of attacks, so they’re not blindsided when one is identified.
