Host-based security refers to a comprehensive approach to protecting individual computer systems from unauthorized access, use, disclosure, disruption, modification, or destruction. Unlike network-based security, which focuses on securing the network infrastructure, host-based security measures are implemented directly on each host or endpoint device within a network.
Host-based security is vital because it safeguards individual devices from various threats and vulnerabilities. It can prevent malware infections, unauthorized access to sensitive data, and system disruptions. Implementing host-based security measures like antivirus software, firewalls, intrusion detection systems, and access controls enhances the overall security posture of an organization by securing each device within the network.
