Description: Host-based access control (HAC) is a security mechanism that restricts access to a specific host on a network based on predefined policies that determine who can or cannot access system resources. This approach allows network administrators to establish specific rules that control access to applications, files, and other resources, ensuring that only authorized users can interact with them. Policies may include criteria such as the user’s IP address, device type, time of day, and other relevant factors. Host-based access control is fundamental for network security, as it helps create security zones within a network infrastructure, limiting the exposure of critical resources to external threats. Additionally, this type of control can be implemented through various security measures such as security software, firewalls, and identity management systems, allowing for more granular and effective access management. In an environment where cybersecurity is increasingly crucial, host-based access control becomes an essential tool for protecting the integrity and confidentiality of information.
