Which is an example of a technical control information assurance?

An example of a technical control in information assurance is the implementation of firewalls. Firewalls monitor and filter incoming and outgoing network traffic based on predetermined security rules, helping to prevent unauthorized access to or from a private network. This control is crucial for protecting sensitive information and maintaining the integrity of systems. Other examples include encryption and intrusion detection systems, which also help safeguard data and ensure secure communications.
