Description: Host security refers to the measures implemented to protect a computer system, known as a ‘host’, from various threats and vulnerabilities. This includes the protection of hardware, software, and data, as well as access management and monitoring of suspicious activities. Host security is fundamental in network architecture, as each device connected to a network can be an entry point for attacks. The main features of host security include the installation of antivirus software, firewalls, intrusion detection systems, and regular updates of the operating system and applications. Additionally, it focuses on network segmentation, which involves dividing a network into smaller subnets to limit access and contain potential security breaches. Implementing security policies, such as user authentication and password management, is also crucial for protecting hosts. In various environments, host security becomes a priority, as data loss or service disruption can have significant consequences. In summary, host security is an essential component of cybersecurity, aimed at safeguarding the integrity, confidentiality, and availability of computer systems.
