Which two actions would provide the minimum security requirements for a small office network?

Implementing a firewall is a fundamental action to provide minimum security requirements for a small office network. A firewall acts as a barrier between a trusted internal network and untrusted external networks, such as the Internet. It controls incoming and outgoing network traffic based on predetermined security rules. This is crucial for protecting sensitive data, preventing unauthorized access, and mitigating the risk of cyber threats such as malware, ransomware, and intrusions.

Firewalls can be either hardware or software-based and serve to filter traffic based on IP addresses, ports, and protocols, adding an essential layer of security that is necessary for safeguarding the network's integrity.

While installing antivirus software is also important for protecting individual devices against malware and other threats, a firewall provides broader protection for the entire network by managing traffic at the boundary. Static IP addresses could simplify the network within certain configurations but don’t enhance security by themselves. Regularly changing network cables may contribute to hardware maintenance, but it does not have a direct impact on the network's overall security posture. Thus, implementing a firewall stands out as the crucial step for a small office to achieve minimum security requirements.
