This area focuses on the deployment of both hardware and software solutions to protect a computer network from unauthorized access. Such measures are important for organizations to defend their assets against potential threats.
Application Security
This area includes the protection of software applications and devices from various threats. Regular updates to applications are important to ensure their defence against frequent attacks.
