What is HIDS in Cybersecurity?A HIDS (Host Intrusion Detection System) is software that detects malicious behavior on the host.
It monitors all the operating system operations, tracks user behavior, and operates independently without human assistance.How does a Host-based Intrusion Detection System work?HIDS operates at the OS level, unlike others antivirus systems that operate at the application level.
It monitors the behavior of programs running on the computer’s operating system to detect any unauthorized or suspicious activity.
This type of protection is typically installed on servers with sensitive information such as databases and financial records.
This system consists of two parts: the agent and the monitor.The agent resides in the monitored computer, and it gathers information from the system’s hardware, directories, files, processes running, network traffic, and many more.
This data is then sent to a central location where it’s analyzed by a monitoring program that looks for suspicious activities like:Unauthorized access to the system.Hacking into the computer remotely.Trying to change critical system settings.Changes to files or programs, etc.When an intrusion is detected, the software monitors what’s going on and sends alerts to administrators who can then take measures.
Security information and event management (SIEM) has evolved gradually over the past decade.
It helps the IT teams to be a lot more proactive in fighting cyber-security threats.
It offers a more centralized approach to solving enterprise security issues.
The unique aspect of security information and event management is that it combines both Security Event Management (SEM) with Security Information Management (SIM).
Security Event Management carries out a detailed analysis of event data in real-time.
This helps to provide even correlation, incidence response, and identifying threats.
