Security Test: TLS Protocol Configuration¶

Scanner(s) Support¶

Description¶

Default Severity: high

TLS configuration issues occur when sensitive data is sent over the network without proper protection, and developers might accidentally leave weak settings in place. This means that although HTTPS is supposed to keep data safe and verify server identity through certificates, bad configurations—like outdated protocols, weak encryption ciphers, or mismanaged certificates—can open the door to attackers. Essentially, if HTTPS isn’t set up correctly, attackers might sniff data or even perform impersonation attacks, making it risky for transmitting credentials or other private information. Developers often overlook the details in setting up the right protocols and checking certificates, leading to vulnerabilities that could be exploited if not fixed.
