Your company’s network security is paramount in the modern, interconnected digital landscape. As the number of cyberattacks increases, it becomes increasingly essential for companies of all sizes to take proactive measures to protect their most valuable assets. Regarding strengthening your defences, Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS) stand out as two crucial components.
Intrusion prevention and detection systems are critical to preventing and detecting intrusions, malware, and security holes (IPS and IDS, respectively). Although these phrases are sometimes used interchangeably, you must grasp their distinct qualities to make informed judgments concerning the security of your company’s network.
This post will explain what IPS and IDS are, how they work, and their advantages and disadvantages. Businesses may better defend themselves from the ever-evolving threats in the digital arena if they have a clearer understanding of these various security solutions.
In this article, we’ll investigate how intrusion prevention systems (IPS) and intrusion detection systems (IDS) function, examine some practical applications of these technologies and offer advice on selecting the optimal security solution for your business. This blog will provide the tools to protect your company’s most valuable assets, whether you’re an IT pro, a business owner, or just interested in network security.
Let’s dive in and learn more about intrusion prevention systems (IPS) and intrusion detection systems (IDS) and how they may strengthen network security for your business.
What Is an IDS (Intrusion Detection System), and How Does It Work?
To identify security breaches and potential threats, businesses deploy intrusion detection systems (IDS) to monitor their networks and analyse events as they occur. The prevention of cyberattacks is the primary function of these security measures.
An intrusion detection system (IDS) is a form of network monitoring designed to detect malicious activity on a network and notify appropriate personnel. These warnings allow security personnel to look into the problems and take action to fix them before any serious harm is done.
IDS can be deployed in either a host-based (HIDS) or network-based (NIDS) fashion. While NIDS solutions monitor and defend whole company networks, HIDS is implemented at the endpoint level and safeguards individual endpoints.
Intrusion detection systems (IDS) vary from one another in more ways than only where they’re installed. Signature-based IDS uses fingerprinting to detect known threats like malware. The signature of the malicious traffic is then recorded and added to the database. New threats are identified by constantly comparing this collection of signatures to active network traffic. This IDS can quickly and reliably identify common security threats.
Because warnings are only issued when a confirmed threat is found, false positives are incredibly uncommon. However, signature-based IDS solutions are useless against zero-day vulnerabilities because they cannot identify threats they have not seen before.
However, anomaly-based IDS functions by first modelling “normal” network activity. Network anomalies are flagged as potential risks, and notifications are delivered to security staff based on how closely future network activity matches this behaviour model. This IDS can identify previously unknown threats. However, it’s conceivable for there to be both false positives and false negatives.
Lastly, hybrid IDS employs signature-based and anomaly-based threat detection to quickly and accurately identify cyberattacks.
The Benefits and Drawbacks of IDS
An IDS will alert you if it detects anything fishy on your network or devices. Errors in configuration, infections, viruses, and unauthorised access can all be reported with the help of an IDS.
Significant advantages of IDS include:
- Immediate alerts in the event of malicious behaviour.
- Observation of linkages and traffic in a network.
- Monitoring the transmission of a virus (if one is found) is essential for understanding its impact.
There are benefits to using an IDS because it alerts you to potential dangers, but there are also some negatives. For instance, it will alert you to potential dangers or harm to your system, but you’ll need to take matters into your own hands and quickly fix them. Your team’s time, energy, and expertise are needed for this.
What Is an IPS (Intrusion Prevention System)?
As with intrusion detection systems, intrusion prevention systems (IPS) look for and eliminate potential danger.
Intrusion prevention systems are hardware or software that, like intrusion detection systems, keep a constant eye on network activities. While IDS can report on the discovered threats, restrict traffic from a particular source, drop packets, or reset the connection, IPS can automatically take the required action to counter the attacks. Some IPS tools can set up a “honeypot” (a decoy with false data) to trick hackers into leaving their real targets alone.
Intruder prevention systems (IPS) are essential to business security nowadays. The proliferation of cloud-based software also implies that businesses now function in increasingly interconnected settings. While this offers many advantages, it also leaves the cloud platform open to assault if safeguards aren’t in place.
Automated security solutions, such as IPS, are more critical than ever before as the number and sophistication of attacks on enterprise systems increase. With this technology, businesses can protect their networks in near real-time without overburdening their security teams. To achieve this, it scans through a lot of traffic at once without slowing down the network. It is common practice for security vendors to bundle IPS with UTM or NGFW solutions.
Between the source and the target of a network’s traffic is where IPS solutions are installed. Intruder Prevention Systems (IPS) may employ several methods for doing so. Signature-based intrusion prevention systems, for instance, do this by comparing network activity to known threat signatures. While effective at fending off already identified attacks, this approach generally fails to discover newly developed dangers.
Anomaly-based IPS, on the other hand, keeps an eye out for anything out of the ordinary by comparing network traffic in real-time to a predetermined baseline of usual behaviour. While this method is superior at detecting new threats, it has a larger false positive rate and a lower false negative rate than signature-based IPS. Modern intrusion prevention systems (IPS) incorporate AI and ML to enhance anomaly-based monitoring capabilities and decrease false alerts.
Finally, policy-based IPS uses predefined organisational security policies to identify and prevent threats. Due to the manual labour involved in creating and configuring relevant policies, signature-based and anomaly-based IPS are more commonly used.
The Benefits and Drawbacks of IPS
With an IPS, you can exert more command over your network and your system with little effort. Like an IDS, it can detect harmful behaviour, but unlike an IDS, it can also respond to threats to stop them. This relieves you of the need to take corrective action.
Critical advantages of IPS include:
- Facilitates less work for IT maintenance teams.
- Sends alerts to system administrators in the event of questionable behaviour.
- When network faults are identified, connections are reset.
- Specifies which types of incoming data are permitted or prohibited.
- Offers comprehension of dynamic data flows. Prevents any further damage to your networks caused by detected malicious activity.
- Identifies the presence of unknown hosts and networks.
Network and bandwidth performance must be high for an IPS to identify and stop intrusions effectively. An IPS may cause performance issues for your company’s infrastructure if your network or bandwidth needs to be improved.
The Similarities Between Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS)
Both intrusion prevention systems and intrusion detection systems serve to safeguard a network’s vital components. Network traffic is compared to a database of cyber attack signatures or a “normal” network behaviour model to identify potential risks.
Efficiently Enforce Company Policies
Policies might be challenging to enforce in a remote workforce. The capacity to enforce policies is another area in which IDS and IPS are similar, as it helps to guarantee highly secure and ethical corporate operations.
It is possible to implement enterprise-level security rules with the help of intrusion detection and prevention systems. If a company-wide policy requires a particular VPN service, IPS can be set up to prevent traffic from going via any other VPN. These tools, logs and reports can be utilised to develop operational and security guidelines and training purposes.
Made for Today’s Business Needs
Enterprise networks are experiencing more access points and larger traffic volumes than ever due to the rise of remote work in the post-pandemic business landscape. As a result, keeping an eye on a network manually is an arduous task, especially in the cloud with all its related services. In addition, the number and complexity of cyber threats encountered by enterprise security teams continue to expand.
This means that state-of-the-art IDS and IPS solutions are an essential component of the cybersecurity systems of any progressive business in the present day. With the help of these automated security systems, businesses can respond quickly and effectively to threats. These systems benefit significantly from being regularly updated so that they are always aware of the most recent security risks.
Using Signature Databases or Behaviour Models for Operation
Both IDS and IPS, which are used to safeguard business networks, rely on signature or behavioural modelling to identify and block potential threats. Even more advanced cybersecurity solutions may use a combined strategy of the two. These cybersecurity solutions monitor network activity and notify relevant IT staff or even take automatic action in the event of a threat.
When spotting common cyber threats, signature-based intrusion detection and prevention systems excel. These tools examine network information in light of a set of established indicators of compromise.
Facilitate Conformity and Save Time
Many governments have passed laws mandating that businesses protect their customers’ personal information. This is especially true for businesses in highly confidential sectors like healthcare and banking. Spending on intrusion detection systems (IDS) and intrusion prevention systems (IPS) is a necessary cost of compliance with the regulations. These safety measures are essential for meeting the many regulations that must be followed. They also keep audit logs that can be used in enquiries into compliance.
Put Automation to Use
IDS and IPS enable automation to safeguard highly digitised organisational environments from cyber threats, unlike traditional cybersecurity methods that necessitate constant monitoring by security staff. Thanks to this, IT departments can protect their networks from cyberattacks with fewer person-hours and fewer dollars.
Intrusion detection and prevention systems provide network security through either hardware or software mechanisms. In the former, sensors are deployed throughout strategic nodes of the corporate network to collect and analyse data. In the latter, tools for monitoring incoming and outgoing traffic are installed on network-connected devices. These systems will sound an alarm whenever a potential danger is identified. IPS can also take further actions automatically based on the rules and policies set up.
Comparison of Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS)
Intrusion prevention systems (IPS) regulate who can access a computer network and who can’t to prevent malicious intrusion. These systems are meant to monitor intrusion data, look into the growing threat, and act accordingly to stop an attack from taking hold.
Intrusion detection systems (IDS) do nothing more than monitor the network and notify admins of suspicious activity. The goal of intrusion detection system (IDS) solutions is to identify security breaches in a network and alert the user so they can take preventative measures.
Despite their usefulness, IDS systems have certain significant downsides that should be taken into account by every company that needs constant monitoring. For instance, intrusion detection systems (IDS) excel at determining when ridding-action is necessary but must improve when eliminating threats independently. To put it, even with an IDS solution, a network or cloud environment is still at risk.
With the addition of the dynamic threat response capability, IPS solutions become even more valuable to a company. Your IT staff will appreciate the IPS’s efficiency and effectiveness because it allows them to take immediate action in response to threats rather than passing the buck to the end user and hoping for the best.
High-level security is essential in today’s networked corporate contexts because it facilitates reliable and secure internal and external data exchange. In the face of external or internal dangers, an IDS System is merely helpful information. When other security measures have failed, an Intrusion Prevention System can be relied on as a flexible safety net. Security measures must evolve alongside the ever-increasing sophistication and complexity of assaults.
Conclusion

Frequently Asked Questions
Why IDS or IPS Is Needed?
What are the benefits of IDS/IPS? IDS/IPS monitors all traffic on the network to identify any known malicious behaviour. One of the ways in which an attacker will try to compromise a network is by exploiting a vulnerability within a device or within software.
Are IDS and IPS Used Together?
Yes, IDS and IPS work together. Many modern vendors combine IDS and IPS with firewalls. This type of technology is called Next-Generation Firewall (NGFW) or Unified Threat Management (UTM).
Where Do IDS and IPS Go for Network Protection?
The IPS is placed inline, directly in the flow of network traffic between the source and destination. This is what differentiates IPS from its predecessor, the intrusion detection system (IDS). Conversely, IDS is a passive system that scans traffic and reports back on threats.
How IPS and IDS Could Prevent Internal Threat in a Network?
An IPS complements an IDS configuration by proactively inspecting a system’s incoming traffic to weed out malicious requests. A typical IPS configuration uses web application firewalls and traffic filtering solutions to secure applications.
What Is the Difference Between IDS, IPS and Antivirus?
An IDS is a technical detective control. An IPS is a technical preventative control. An antivirus program is a technical preventative control. Associating these three control types to an IDS, IPS, and anti-virus will take you far in remembering the basic concept for the exam.
