What is the first line of defense when setting up a network?

Answer 1

The first line of defense when setting up a network is implementing a robust firewall. This acts as a barrier between the internal network and external threats, controlling incoming and outgoing traffic based on predetermined security rules. Additionally, establishing strong access controls, such as user authentication and authorization, further enhances security by ensuring that only authorized users can access sensitive information and resources. Regularly updating and monitoring these defenses is crucial for maintaining network security.
