What is the impact of encryption on data visibility?
Encryption impacts data visibility by necessitating the decryption of traffic for deep inspection. Next-Generation Firewalls (NGFW) require decryption to conduct thorough inspections of Secure Sockets Layer (SSL) traffic, otherwise known as TLS (Transport Layer Security) traffic. This allows the NGFW to identify and mitigate potential threats that would otherwise remain hidden within the encrypted traffic.
C is correct. A. TLS 1.3 traffic cannot be decrypted and monitored. This is incorrect. While TLS 1.3 introduces new security features, it can still be decrypted and monitored with the appropriate tools and techniques.
A or C dunno
Yes, C is the correct answer. Explanation: Encryption enhances data security by making the contents of network traffic unreadable without decryption. However, it also reduces the visibility of monitoring systems, requiring decryption for detailed analysis. Here's how this applies to the options: C. Traffic decryption is needed for deep inspection of SSL traffic via NGFW (Next-Generation Firewalls): For SSL/TLS traffic, decryption is essential to perform deep packet inspection (DPI) and identify threats like malware, phishing, or data exfiltration within encrypted traffic. NGFWs often include SSL/TLS decryption capabilities to inspect such traffic.
Correct answer is C
