Examples of Intrusion Prevention Systems (10 Best IPS Solutions)

Last updated on by Editorial Staff
Intrusion Prevention Systems

Cyber threats have become more sophisticated, so organizations must ensure their networks are secure from malicious actors.

Traditional security systems like firewalls and antivirus software are no longer enough to keep your network safe. Intrusion Prevention Systems (IPS) can provide extra protection against these threats.

Integrated security system IPS is a security technology that helps protect businesses against cyber attacks.

Nevertheless, the systems work differently than the ones described above. Therefore, identifying the distinct types is crucial for understanding the differences among intrusion detection and prevention systems.

Finding the right IPS solution for your business needs is crucial, so we will list the examples of intrusion prevention systems. 

The post is listed the top 10 IPS solutions available today. With this guide, you will have all the information you need to decide which intrusion prevention system is right for you.

What is an Intrusion Prevention System (IPS)?

Intrusion Prevention System (IPS) is a security system that guards a network or system against malicious activity. It works by monitoring and analyzing incoming traffic for suspicious activity, like unauthorized access attempts, malicious code, and other malicious activity.

If any suspicious activity is detected, the IPS will block it from entering the network or system.

It is also known as an intrusion detection and prevention system because IPS is examined as an augmentation of Intrusion detection systems (IDS). Both systems protect the network from malicious activities and operate network traffic. 

IPS records observed events, informs security administrators of important observed events, and produces reports.

How does an IPS work?

An Intrusion Prevention System (IPS) actively monitors and analyzes an organization’s networks, systems, and applications for malicious activities like malware and scripting attacks in real time.

When suspicious activity is detected, it will immediately alert the network administrator, who can then take action to prevent further intrusion.

An IPS uses multiple methods, such as signature-based detection, protocol anomaly detection, heuristic analysis, and rate limiting, to detect malicious traffic before it can cause harm.

It also provides in-depth prevention with sandboxing technologies that allow IT professionals to analyze suspicious files without risking the safety of their system. Ultimately, using an IPS helps organizations stop cyberattacks before they occur.

Types of IPS

Two main types of IPS are

Network-based IPS (NIPS)

Network-based IPS solutions are typically deployed at the perimeter of an organization’s network and monitor inbound and outbound traffic to detect malicious attempts or suspicious behavior.

Host-based IPS (HIPS)

Host-based intrusion prevention systems (HIPS) are specialized security solutions that protect an individual host or device from malicious activity.

They analyze system-level events, like file creations and process executions, to identify potentially malicious activity. HIPS are designed to protect a single host or device, so they are usually deployed alongside other security mechanisms on-premises.

Other types are as follows.

Wireless intrusion prevention system (WIPS)

Wireless Intrusion Prevention System (WIPS) is a specialized security solution to protect wireless networks from malicious activity.WIPS uses heuristic-based technology and deep packet inspection to detect and prevent unauthorized access, man-in-the-middle attacks, and other malicious activities. 

Network behavior analysis (NBA)

A security technique that examines the network traffic for malicious or policy-violating activity. It uses advanced analytics to detect and identify abnormal patterns in network behavior, such as those associated with malware, insider threats, data exfiltration, and other cyber-attacks. 

Host-Based vs. Network-Based

A hosted IPS protects the specific endpoints in their network. It will monitor the traffic in and out of a computer, processes running the system, changes made to the files, etc. Networked solutions provide monitoring of the network. They usually consist of a packet sniffing tool that collects packets from the internet connection.

Techniques used by IPS to detect threats

  • Signature-based detection: This system correlates activity to signatures of well-established threats. The drawback of this method is it can detect already identified attacks but not new ones.
  • Statistical anomaly-based detection: This system compares network activity samples to a benchmark standard to detect abnormal behavior. It is more reliable than signature-based monitoring, although the results can occasionally be inaccurate. The most modern intrusion prevention systems leverage artificial intelligence, machine learning technology, and anomaly-based monitoring for even greater accuracy.
  • Stateful protocol analysis detection: This is a less commonly used method compared to other methods. It follows enterprise security policies and does not allow activities that violate them. 

Benefits of IPS

Increased security

Intrusion prevention systems provide an extra layer of security by monitoring and analyzing network traffic for malicious activity. They can detect suspicious behavior, such as attempts to access unauthorized data or networks, and alert administrators so they can take action quickly.

Improved visibility

An intrusion prevention system provides visibility into the activities occurring on your network in real time, allowing you to identify potential threats before they become a problem. That allows you to proactively address any issues and ensure your organization always remains secure.

Reduced costs

By having an intrusion prevention system in place, organizations can reduce the costs associated with responding to security incidents since they can be identified early on and dealt with quickly rather than waiting until it’s too late.

Improved Compliance

Intrusion prevention systems help organizations meet regulatory requirements by providing detailed audit trails of user activity, making it easier to comply with industry standards such as PCI DSS or HIPAA.

Enhanced Productivity

With an IPS in place, organizations benefit from improved productivity because employees can work without interruption from malicious attacks or other security threats.

Limitations of IPS

IPSs are not always perfect. They don’t have software to help with network devices or keep people from copying information. IPSs and IDSs can only stop intruders when they start to get into the network. The purpose of this system is to keep data and resources safe.

FAQs

What types of cyber attacks are prevented by IPS?

IPS prevents various types of cyber attacks by analyzing network traffic and identifying and responding to potential threats. Some of the attacks that IPS can prevent include
1. Malware attacks – These prevent malware from sneaking into a network by analyzing incoming traffic and blocking suspicious files or downloads. It prevents malware from spreading within the network by isolating infected machines.
2. Denial-of-service (DoS) attacks – It prevents DoS attacks by blocking incoming traffic, sending an overly large number of requests to the network, thus preventing the network from being overwhelmed and causing downtime.
3. SQL injection attacks – It filters incoming traffic and detects attempts to inject malicious code into SQL statements.
4. Cross-site scripting (XSS) attacks – It prevents XSS attacks by analyzing incoming traffic and detecting any attempts to exploit vulnerabilities in web applications.
5. Zero-day attacks – It uses advanced threat intelligence and ML algorithms to detect and respond to new and emerging threats in real-time.
