What is IPS Technology? Benefits, Types & Potential Risks for Businesses

Introduction

Intrusion Prevention Systems (IPS) are an essential element of a robust cybersecurity strategy. In today’s digital world, organizations must take extra precautions to protect themselves from malicious actors and data breaches. IPS technology is one way to do this, as it provides an additional layer of protection against potential cyber threats. But what exactly is IPS technology and how can it benefit businesses? In this article, we’ll explore the definition of IPS technology, its benefits, implementation guide, different types of solutions, and potential risks.

Definition of IPS Technology

Intrusion Prevention Systems (IPS) is a type of security system that uses software or hardware to detect and prevent malicious activity on a network. It monitors incoming and outgoing traffic to identify suspicious behavior and block any malicious activities before they can cause damage. IPS technology is often used in combination with other security measures such Firewalls, Anti-Virus Software, and Data Loss Prevention (DLP) systems.

Overview of How IPS Technology Works

IPS technology works by analyzing the content of both incoming and outgoing network traffic. It then applies a set of rules and patterns to determine if there is any malicious activity. If it detects anything suspicious, it will immediately take action to block the traffic and alert the administrator. The exact actions taken by the IPS may vary depending on the configuration, but they typically involve dropping packets, resetting connections, or blocking IP addresses.

Benefits of IPS Technology in Businesses

IPS technology offers numerous benefits for businesses. Here are some of the most notable advantages:

Improved Network Security

IPS technology enhances overall network security by providing an additional layer of protection against malicious actors. By monitoring all traffic, it can detect and block malicious activities before they can cause any damage. According to a study conducted by the Ponemon Institute, “the presence of an IPS solution was found to decrease the risk of a successful attack by 75%.”

Increased Visibility into Network Activity

IPS technology also provides increased visibility into the network. It can monitor all traffic and generate reports that provide detailed information about the activity taking place on the network. This allows administrators to quickly identify any potential threats and take appropriate action.

Reduced Cost of Compliance with Regulations

Organizations are increasingly required to comply with various regulations, such as HIPAA and PCI-DSS. An IPS system can help reduce the cost of compliance by providing an additional layer of protection and monitoring traffic to ensure compliance with the relevant regulations.

Guide to Implementing an IPS System

Implementing an IPS system can be a complex process, but following the right steps can make it much easier. Here’s a guide to help you get started:

Identifying the Right IPS Solution

The first step is to identify the right IPS solution for your organization. You should consider factors such as the size of your network, the type of traffic you need to monitor, and your budget. Once you’ve identified a suitable solution, you can move on to the next step.

Preparing Your Network for IPS Deployment

Before deploying an IPS system, you should ensure that your network is properly prepared. This includes setting up access control lists, segmenting the network, and configuring firewalls. You should also ensure that your network is running the latest version of the operating system and that all patches have been applied.

Integrating the IPS Solution into Your Network

Once your network is ready, you can begin the process of integrating the IPS solution into your network. This involves configuring the system to meet your specific needs, setting up the sensors and other components, and testing the system to ensure that it is working correctly.

Different Types of IPS Solutions

There are several different types of IPS solutions available. Here are some of the most common:

Host-Based IPS

Host-based IPS (HIPS) is a type of IPS that is installed directly onto the host machine. It monitors all activity on the host machine and takes action if it detects any suspicious activity. HIPS is often used in conjunction with other security measures such as antivirus software and firewalls.

Network-Based IPS

Network-based IPS (NIPS) is a type of IPS that is installed on a network device, such as a router or switch. It monitors all traffic on the network and takes action if it detects any malicious activity. It is often used in conjunction with other security measures such as firewalls and antivirus software.

Cloud-Based IPS

Cloud-based IPS (CIPS) is a type of IPS that is hosted in the cloud. It monitors all traffic to and from the cloud and takes action if it detects any suspicious activity. CIPS is often used in conjunction with other security measures such as antivirus software and firewalls.

Potential Risks of Deploying IPS Technology

Although IPS technology can be beneficial, there are also potential risks associated with its deployment. Here are some of the most common:

False Positives and False Negatives

IPS technology is not perfect and may produce false positives and false negatives. A false positive occurs when the IPS incorrectly identifies legitimate traffic as malicious and blocks it. A false negative occurs when the IPS fails to detect malicious traffic. Both of these scenarios could result in legitimate traffic being blocked or malicious traffic going undetected.

Overhead Caused by IPS Scans

IPS technology can also cause a significant amount of overhead due to the constant scanning of traffic. This can lead to slower network performance and decreased productivity. It is important to keep this in mind when considering an IPS solution.

Potential for Compromised Security

Finally, there is always the potential for an IPS system to be compromised by a malicious actor. This could result in sensitive information being exposed or the system being used to launch attacks. It is important to ensure that your IPS system is properly configured and regularly updated to help minimize the risk of compromise.

Conclusion

Intrusion Prevention Systems (IPS) are an essential element of a robust cybersecurity strategy. They provide an additional layer of protection against potential cyber threats, improved visibility into network activity, and reduced cost of compliance with regulations. When implementing an IPS system, it is important to identify the right solution, prepare your network, and integrate the system into your network. There are three main types of IPS solutions: Host-Based, Network-Based, and Cloud-Based. While IPS technology has many benefits, there are also potential risks associated with its deployment, including false positives, false negatives, overhead caused by scans, and the potential for compromised security.
