Intrusion Detection Systems and Intrusion Prevention Systems

Computer networks are increasingly popular all over the world as the technology being implemented in the organization is increasing to help employees process their work and communicate with each other. As technology continues to evolve, hackers are trying to gain access to the organization's network, increasing the possibility of data and information being stolen or lost. There are many systems that help to detect and alert organization attacks and to prevent the occurrence of attacks.

Intrusion Detection and Intrusion Prevention Systems Intrusion detection and intrusion prevention systems record detailed information about suspicious behavior and detected attacks and intrusion prevention systems that are performed to prevent ongoing malicious activity. File Integrity Check Because some intrusion detection systems such as software run regularly instead of continuously, instead of continuously generating .4 remote access software, generate log entries in batches I will. Remote access is usually permitted and protected via a virtual private network (VPN). The VPN system usually records the successful login attempts and failed login attempts, the date and time each user connected and disconnected, and the amount of data sent and received for each user session. For VPN systems that support fine-grained access control, such as many SSL (Secure Sockets Layer) VPNs, details on resource usage may be recorded.

Intrusion detection prevention system (IPS), also called Intrusion Detection Prevention System (IDPS), is a network security device that monitors network or system activity for malicious activity. The main function of the intrusion prevention system is to identify malicious activity, record information about that activity, report it, block or block it. Intrusion prevention systems are considered an extension of intrusion detection systems to monitor network traffic activity, malicious activity of the system, or both. Unlike intrusion detection systems, the main difference is that the intrusion prevention system is on-line and can actively prevent or block detected intrusions. : 273: 289 IPS can take measures such as sending alerts, destroying detected malicious packets, resetting connections, blocking traffic from IP address infringement.
