Keep an eye out for signs of abnormal threat activity on the computers in your network.
Because cyber threats are now more prevalent than ever, having the capacity to detect assaults that breach perimeter security is critical to maintaining business continuity. Host-based intrusion detection systems (HIDS) assist organizations in identifying threats inside the network perimeter by monitoring host devices for malicious activity that, if left undetected, could result in serious breaches. Host-based intrusion detection systems (HIDS) are used to detect threats inside the network perimeter.
What exactly is HIDS?
The use of host-based intrusion detection systems allows organizations to monitor the activities and applications that operate on devices such as servers and workstations, among other things. In addition, HIDS monitors changes to registry settings and important system configuration, as well as modifications to log and content files, and notifies the user if any unauthorized or abnormal activity occurs.
HIDS technologies are ‘passive’ in nature, which means that their primary function is to detect abnormal activity rather than to prevent it. To counteract this, HIDS solutions are frequently used in conjunction with intrusion prevention systems (IPS), which are referred to be “active.”
Network-based intrusion detection systems (NIDS) and SIEM solutions, which collect and analyze security events from numerous sources, are frequently used in conjunction with host-based intrusion detection systems (HBIDS) in organizations seeking greater levels of security visibility and control.
What is the operation of HIDS?
To identify threats, host-based intrusion detection systems (also known as ‘HIDS agents’) require sensors to be deployed on monitorable assets to function properly.
A hybrid intrusion detection system (HIDS) makes use of a combination of signature-based and anomaly-based detection approaches. When a file is detected as malicious, it is compared to a database of signatures that have already been identified as harmful. Anomaly-based detection compares occurrences to a baseline of ‘normal’ system behavior in order to identify anomalies.
- Intrusion detection systems that are based on the host can detect a wide range of threats, including:
- Unauthorized attempts to log in and get access
- Privileges are being increased.
- Changing the binary executables of an application, its data, and its configuration files
- Unwanted apps are being installed on your computer.
- Processes that go awry
- Service interruptions or failures that affect mission-critical applications
