How does CANES enhance cybersecurity for naval operations?

The answer that highlights how CANES enhances cybersecurity for naval operations focuses on the implementation of various layers of defense, including firewalls and intrusion detection systems. This approach embodies the principle of defense in depth, which is crucial for effective cybersecurity. By utilizing multiple security measures, CANES can protect sensitive data and systems from a range of threats.

Firewalls serve as a barrier that monitors and controls incoming and outgoing network traffic based on predefined security rules, while intrusion detection systems actively monitor network traffic for suspicious activity. Together, these tools create a more secure environment by mitigating risks associated with unauthorized access and potential cyberattacks. This multi-layered strategy is essential for adapting to evolving cyber threats, thereby enhancing overall naval operational security.

The other options, while beneficial in their own right, do not encapsulate the comprehensive defense mechanism provided by the multiple layers of security that CANES implements. Limiting internet access can restrict exposure to threats, having robust anti-virus software protects against known malware, and conducting drills ensures preparedness, but none of these strategies alone can provide the extensive security benefits realized through the layered approach.
