71. Which of the following is the best way to improve the confidentiality of remote connections to an enterprise's infrastructure?
Answer: B
The best way to improve the confidentiality of remote connections to an enterprise's infrastructure is through virtual private networks.
Virtual private networks (VPNs) provide a secure channel for remote users to access an enterprise's infrastructure, ensuring that data transmitted over the internet is encrypted and protected from unauthorized access.
A) Firewalls
Firewalls are essential for monitoring and controlling incoming and outgoing network traffic based on predetermined security rules. However, while they can help protect the network perimeter, they do not provide encryption for data in transit, which is crucial for maintaining confidentiality in remote connections.
B) Virtual private networks
Virtual private networks are specifically designed to enhance the confidentiality and security of remote connections. By encrypting data transmitted between the user's device and the enterprise's network, VPNs significantly reduce the risk of data interception and unauthorized access.
C) Extensive logging
Extensive logging is important for tracking user activity and identifying potential security breaches. However, it does not directly improve the confidentiality of remote connections, as it focuses on monitoring rather than securing the data being transmitted.
D) Intrusion detection systems
Intrusion detection systems (IDS) are used to detect and respond to unauthorized access attempts and other security threats. While they play a critical role in overall security, they do not enhance the confidentiality of data transmitted over remote connections, as they do not provide encryption.
Conclusion
Virtual private networks are the most effective solution for improving the confidentiality of remote connections, as they encrypt data and protect it from unauthorized interception. Other options, such as firewalls, extensive logging, and intrusion detection systems, contribute to security but do not address confidentiality in the same direct manner as VPNs. Thus, VPNs are essential for secure remote access to an enterprise’s infrastructure.
