What is the most appropriate tool to secure internal certificates during HTTPS decryption on a web proxy server?

1. Firewall

2. HSM

3. UTM

4. DLP

The correct answer is: HSM

Using a Hardware Security Module (HSM) is the most appropriate tool for securing internal certificates during HTTPS decryption on a web proxy server because HSMs are specifically designed to manage digital keys and perform cryptographic operations securely. They provide a high level of protection for sensitive keys and certificates, ensuring that they cannot be easily accessed or manipulated, which is crucial when handling HTTPS traffic. When a web proxy server intercepts HTTPS traffic for decryption, it requires access to certificates to establish trust with both the client and the destination server. By utilizing an HSM to store and manage these certificates, organizations can ensure that the keys remain inside a secure hardware environment, thus minimizing the risk of leakage or compromise. This is especially important given the sensitive nature of the data that HTTPS is designed to protect. Other tools mentioned, such as firewalls or Unified Threat Management (UTM) devices, primarily focus on traffic filtering, intrusion detection, and prevention capabilities rather than the secure management of cryptographic keys. Data Loss Prevention (DLP) solutions are aimed at preventing sensitive data from being leaked or misused but do not specialize in the secure handling of certificates or keys used for HTTPS decryption. Therefore, the HSM stands out as the most suitable choice for this
