Those days are gone when the virus was just a virus, and everything else was "just what an enterprise needs"! Nowadays, the most well-known danger that could affect an organization's system comes under the general name "malware" (Malware). These programs are constantly evolving and pose a serious threat to your company's information security.

Before the evolution of Iot and smart sensors, the antiviruses were based on digital signatures of viruses, which provided the most reliable results of detection. However, their ease of use was limited in the frequency of updating their databases. Today, companies like Igzy have developed special intrusion detection and prevention programs to enhance an organization's security capabilities that monitor events on your computer for "malware-specific activity."

Evaluating the effectiveness of intrusion detection and prevention programs can be a hard task, even for professionals. Therefore, any so-called "test results" should be treated with some caution by every organization. It is not nearly enough to just feed a bunch of malware or malicious programs that can be easily detected from their signature. Yes, it will increase the sense of security and indicators, but it can't provide solutions in a real situation. It will be hard for them to detect new malicious programs not included in such "heaps". On the other hand, such results are badly used in advertising because numbers can be a decisive factor for an inexperienced company.

How do intrusion detection and intrusion prevention software works?

In simple terms, intrusion detection software usually checks for changes made by the unwanted programs that can be introduced into your company's systems by cybercriminals. In addition, this software examine complete packets of data - inbound and outbound - to see what data is being transmitted and alert management if any suspicious activity is detected on the company's computer or network.

Today, the market is filled with multiple intrusion detection software. The features and functioning of this software depend on how they are encoded. Still, mostly they utilize checking data packet signatures, changes made to the computer registry, or other areas of interest such as startup programs, data packet format, etc. It allows them to track possible intrusions into the system.

Types of intrusion detection and prevention software:
The intrusion detection and prevention software are available in two types. The first one is a host-based intrusion detection system, and the other is a network intrusion detection system. A network-based intrusion detection software relies on data packets sent over the network to ensure everything is in order. It works on the principle of comparing data packets for known attack types and detecting violations in data packets traveling over the network. Examples of anomalies might be missing signatures, insecure data packet type, etc.

A host-based intrusion system relies more on system settings to determine if any program is trying to force changes on the company's system or computer network.

Over time a modern kind of intrusion detection system from companies like Igzy are getting quite popular. They utilize a top-of-the-line IoT based ecosystem of smart sensors to prevent and inform management about any mishap before it occurs. In addition, they also provide control over safety, security, convenience, and efficiency for businesses.

In short, intrusion prevention system software monitors data packets traveling over the network and alerts management when any attack is suspected or when a policy violation occurs. It will also send notifications if someone tries to break into an organization's network and explain what happened during the cyber attacks, while IPS will try to stop it and deny access. IDS detects unauthorized activity, while IPS blocks unauthorized packets that match a specific malicious signature.

Where to deploy protection?
If an organization decides to install protection on the network, be it IDS / IPS, Iot based, the question arises where to put it. The answer to this question depends on the type of system a company is using. So, it makes no sense to install IDS in front of the firewall or inside the network, and IPS includes all the elements at once, so it can be installed anywhere.

The best way to install an intrusion detection system is in the front of the firewall on the inside of the organization's network. In this way, IDS will not analyze all traffic, but only the one that was not blocked by the firewall. This is evident: why analyze the data that is being blocked. It also reduces the load on the system.

Overview of Igzy Intrusion Detection and Prevention Software
Igzy has been helping out organizations to protect their computers from malware for a long time. Recently it has also been updated with an ecosystem of smart sensors and modern IoT platforms that warns management about changes to the system, which may be a consequence of the work of malicious programs. For achieving the goal, it uses many features like taking a snapshot of the system settings and modifying management about any changes. It also uses a heuristic approach in its work, which gives more confidence that your organization will not get new malware than traditional signature scanners, which are highly dependent on the availability of updates.
