An Intrusion Detection System (IDS) and Intrusion Prevention System (IPS) are excellent technologies to detect and prevent malicious activities on your networks, systems, and applications.

Using them makes sense because cybersecurity is a major issue that businesses of all shapes and sizes face.

Threats are ever-evolving, and businesses face new, unknown threats that are difficult to detect and prevent.

This is where IDS and IPS solutions come into the picture.

Although many throw these technologies into pits to compete with each other, the best way could be to make them complement each other by utilizing both in your network.

In this article, we will look at what IDS and IPS are, how they can help you, and some of the best IDS and IPS solutions in the market.

What’s Intrusion Detection System (IDS)?

An Intrusion Detection System (IDS) refers to a software application or device to monitor an organization’s computer network, applications, or systems for policy violations and malicious activities.

Using an IDS, you can compare your current network activities to a threat database and detect anomalies, threats, or violations. If the IDS system detects a threat, it will immediately report it to the administrator to help take remedies.

IDS systems are mainly of two types:

  • Network Intrusion Detection System (NIDS): NIDS monitors traffic flow in and out of devices, compares it to known attacks, and flags suspicion.
  • Host-Based Intrusion Detection System (HIDS): It monitors and runs important files on separate devices (hosts) for incoming and outgoing data packets and compares current snapshots to those taken previously to check for deletion or modifications.

Furthermore, IDS can also be protocol-based, application protocol-based, or a hybrid IDS combining different approaches based on your requirements.

How Does an IDS Work?

IDS comprises various mechanisms to detect intrusions.

  • Signature-based Intrusion detection: an IDS system can identify an attack by checking it for a specific behavior or pattern like malicious signatures, byte sequences, etc. It works great for a known set of cyberthreats but might not do that well for new attacks where the system can’t trace a pattern.
  • Reputation-based detection: This is when an IDS can detect cyberattacks according to their reputation scores. If the score is good, the traffic will get a pass, but if it’s not, the system will inform you immediately to take action.
  • Anomaly-based detection: It can detect computer and network intrusions and violations by monitoring the network activities to classify a suspicion. It can detect both known and unknown attacks and leverages machine learning to build a trustworthy activity model and compares it against new behaviors.

What is an Intrusion Prevention System (IPS)?

An intrusion prevention system (IPS) refers to a network security software application or device to identify malicious activities and threats and prevent them. Since it works for both detection and prevention, it’s also called the Identity Detection and Prevention System (IDPS).

IPS or IDPS can monitor network or system activities, log data, report threats, and thwart the issues. These systems can usually be located behind an organization’s firewall. They can detect issues with network security strategies, document current threats, and ensure no one violates any security policy in your organization.

For prevention, an IPS can modify security environments like changing the threat content, reconfiguring your firewall, and so on. IPS systems are of four types:

  • Network-Based Intrusion Prevention System (NIPS): It analyses data packets in a network to find vulnerabilities and prevent them by collecting data about applications, allowed hosts, operating systems, normal traffic, etc.
  • Host-Based Intrusion Prevention System (HIPS): It helps protect sensitive computer systems by analyzing host activities to detect malicious activities and prevent them.
  • Network behavior analysis (NBA): It depends on anomaly-based intrusion detection and checks for deviation from normal/usual behavior.
  • Wireless intrusion prevention system (WIPS): It monitors the radio spectrum to check unauthorized access and takes measures to encounter it. It can detect and prevent threats such as compromised access points, MAC spoofing, denial of service attacks, misconfiguration in access points, honeypot, etc.

How Does an IPS Work?

IPS devices scan network traffic thoroughly using one or multiple detection methods, such as:

  • Signature-based detection: IPS monitors network traffic for attacks and compares it to predefined attack patterns (signature).
  • Stateful protocol analysis detection: IPS identifies anomalies in a protocol state by comparing current events with predefined accepted activities.
  • Anomaly-based detection: an anomaly-based IPS monitors data packets by comparing them against a normal behavior. It can identify new threats but might show false positives.

After detecting an anomaly, the IPS device will perform inspection in real-time for every packet traveling in the network. If it finds any packet suspicious, the IPS can block the suspicious user or IP address from accessing the network or application, terminate its TCP session, reconfigure or reprogram the firewall, or replace or remove malicious content if it remains after the attack.

How Can an IDS and IPS Help?

Understanding the meaning of network intrusion can enable you to get better clarity on how these technologies can help you.

So, what’s network intrusion?

A network intrusion means an unauthorized activity or event on a network. For example, someone trying to access an organization’s computer network to breach security, steal information, or run malicious code.

Endpoints and networks are vulnerable to various threats from every possible side.

  • Malware
  • Social engineering threats like phishing, whaling, spear phishing, and more
  • Password theft

In addition, unpatched or outdated hardware and software along with data storage devices can have vulnerabilities.

The results of a network intrusion can be devastating for organizations in terms of sensitive data exposure, security and compliance, customer trust, reputation, and millions of dollars.

This is why it’s essential to detect network intrusions and prevent mishaps when it’s still time. But it requires understanding different security threats, their impacts, and your network activity. This is where IDA and IPS can help you detect vulnerabilities and fix them to prevent attacks.

Let’s understand the benefits of using IDA and IPS systems.

Improved Security

IPS and IDS systems help improve your organization’s security posture by helping you detect security vulnerabilities and attacks in the early stages and prevent them from infiltrating your systems, devices, and network.

As a result, you will encounter fewer incidents, secure your important data, and safeguard your resources from getting compromised. It will help withhold your customer trust and business reputation.


Using IDS and IPS solutions help automate security tasks. You no longer need to set and monitor everything manually; the systems will help automate these tasks to free your time on growing your business. This not only reduces effort but also saves costs.


IDS and IPS help you protect your customer and business data and help during audits. It enables you to abide by compliance rules and prevent penalties.

Policy Enforcement

Using IDS and IPS systems is an excellent way to enforce your security policy throughout your organizations, even on the network level. It will help prevent violations and check every activity in and out of your organization.

Increased Productivity

By automating tasks and saving time, your employees will be more productive and efficient at their work. It will also prevent frictions in the team and unwanted negligence and human errors.

So, if you want to explore the full potential of IDS and IPS, you can use both these technologies in tandem. Using IDS, you will know how traffic moves in your network and detect issues while utilizing IPS to prevent the risks. It will help protect your servers, network, and assets provide 360-degree security in your organization.

Now, if you are looking for good IDS and IPS solutions, here are some of our best recommendations.
