Which of the following is the best way to improve the confidentiality of remote connections to an enterprise's infrastructure?

Firewalls primarily focus on regulating network traffic based on predetermined security rules, such as blocking or allowing specific ports or IP addresses. While firewalls are essential for network security, they primarily serve to control access and filter traffic rather than directly enhancing the confidentiality of remote connections.

Extensive logging involves recording detailed information about system activities and events, which is crucial for monitoring and investigating security incidents. However, while logging is important for auditing and identifying potential security breaches, it does not directly improve the confidentiality of remote connections.

Intrusion detection systems (IDS) are designed to detect and respond to unauthorized access or malicious activities within a network. While IDS play a critical role in identifying security incidents, they are more focused on real-time threat detection and response rather than specifically bolstering the confidentiality of remote connections.
