Exam NetSec-Analyst Topic 3 Question 47 Discussion

The error 'ssl_error_ssl: ssl_routines: ss13_read_bytes: sslv3 alert handshake failure' specifically points to an SSL/TLS handshake issue. Option B (Correct): Many modern servers disable older, insecure protocols like SSLv3. If the firewall is attempting to connect using SSLv3 and the server only supports TLS 1.2/1.3, this handshake failure will occur. This is a very common reason for this specific error message. Option A (Correct): An expired or untrusted certificate on the server side would also lead to a handshake failure, as the firewall cannot establish a secure, trusted connection. The client (firewall) rejects the server's certificate during the handshake. Option C is unlikely to cause an SSL handshake failure; it would manifest as connection refused or rate limiting. Option D would prevent any connection, not specifically an SSL handshake failure. Option E would cause parsing errors after a successful fetch, not a handshake failure during the initial connection.
