Intrusion Detection Systems are known as Intrusion Detection Systems , or IDS. The short answer to the question of what an IDS is is that they are devices and software that monitor malicious attacks, activities, and policy violations on systems and networks.

As a result, the detected situations are reported to the administrator. Similarly, SIEM can be used to collect them in a central location. Some of these threats are as follows;

Back Doors
Payload
Ransomware Viruses
Rootkit
Keylogger
Denial Of Service
Eavesdropping
Advanced Persistent Threat
Viruses, Worms and Trojans
Malware
Feeding
Data Scraping
These can be increased and help detect IDS. Apart from this, it is sometimes done to find and fix weak points in the system. However, these are attacks that are carried out in a coordinated and planned manner upon the request of a company. The goal is to find the vulnerability and then take the necessary actions to solve it.

IDS also has the aspect of stopping attacks, but this happens at earlier stages.

What are Intrusion Detection Methods?
Intrusion detection has three detection methods. These are as follows;

Signature-based attack detection method: It involves detecting the attacker by looking for patterns, such as malicious scripts, in network traffic. However, if there is no pattern, it makes it impossible to detect if they are using a new attack.
Anomaly-based intrusion detection method: It is designed to detect unknown attacks. It is basically comparing new behaviors using machine language. Thus, it allows detection. However, it can also give false alarms.
Stateful protocol analysis: It includes processes such as comparing suspicious activities and detecting deviations.
Intrusion detection systems basically serve to detect, record and report an attack. Thus, detailed information is obtained and precautions are taken. However, in the early stages of the attack, it also has a preventive nature.

What are Intrusion Prevention Systems?
Intrusion Detection Systems have four different types. This way, the network can be monitored more efficiently and actively, and detections can be made earlier. The types in question are as follows;

NIPS – Network-Based Intrusion Detection System: Analyzes protocol activity to detect suspicious traffic. Monitors the entire network.
WIPS – Wireless Intrusion Prevention Systems: Analyzes wireless network protocols for suspicious traffic.
NBA – Network Behavior Analysis: Examines the system to detect threats such as DDoS attacks and malware.
HIPS – Computer-Based Intrusion Prevention Systems: Identifies deviations by comparing observed events with predetermined benign profiles.
Thus, attacks on the system can also be detected. Our company , within the scope of Intrusion Detection Systems solutions, allows you to find weak points in your system and produce a solution, as well as to have detailed information about the attacks. The methods used are compatible with your systems.
