Exam SY0-601 topic 1 question 517 discussion

In this scenario, the weakest design element is that encrypted VPN traffic will not be inspected when entering or leaving the network. Since the traffic is encrypted, the DLP (Data Loss Prevention) appliance will not be able to inspect the content of the data packets passing through the VPN tunnel. This lack of inspection can potentially allow malicious or unauthorized data to be transmitted without detection. To enhance security, it is essential to implement a solution that allows for the inspection of encrypted VPN traffic. One approach is to deploy a next-generation firewall (NGFW) with SSL/TLS decryption capabilities. The NGFW can decrypt the VPN traffic, inspect it for potential threats or sensitive data, and then re-encrypt it before sending it to its destination. By doing so, the organization can maintain security while still enabling remote users to access corporate resources through the VPN.

When users connect via split-tunnel VPNs, their internet-bound traffic doesn’t pass through the corporate data center. As a result: The DLP appliance does not inspect internet-bound traffic. The firewall at the internet border does not filter this traffic. While this design optimizes internet performance for users, it weakens security. The DLP appliance’s effectiveness relies on inspecting all traffic, including internet-bound data. By excluding this traffic, the organization risks data leakage or policy violations.

C. Encrypted VPN traffic will not be inspected when entering or leaving the network.

A. The DLP appliance should be integrated into an NGFW (Next-Generation Firewall). Integrating the DLP appliance into a NGFW would enhance the overall security posture. A NGFW combines traditional firewall functionality with advanced security features such as intrusion prevention, application awareness, and content filtering. This integration would allow for more effective handling of data loss prevention and security monitoring. Option C (Encrypted VPN traffic not being inspected) is indeed a concern, but it's a limitation imposed by the necessity of maintaining the security and privacy of VPN traffic, rather than a design choice.

Can anyone explain all options ?

DLP won't be able to inspect data that is passing through a VPN
