Description: Tactical Security is a strategic approach to implementing security measures in information systems based on mandatory access control. This approach allows administrators to define detailed security policies that regulate how processes and users interact with system resources. Through various security frameworks, rules can be established that limit the actions a process can take, even if the user has elevated privileges. This is crucial in environments where security is paramount, as it helps prevent unauthorized access and contain potential security breaches. Tactical Security is not only applied to specific systems but also extends to other areas such as network security, firewalls, and cybersecurity, where specific strategies are implemented to protect the integrity, confidentiality, and availability of information. In an increasingly digitalized world, Tactical Security becomes an essential component for defending against cyber threats, ensuring that critical infrastructures and sensitive data are adequately protected.
