Weak cyphers can leave sensitive transactions exposed to brute force attacks and man-in-the-middle (MitM) attacks. Stronger cyphers, which are almost impossible to crack using modern computers, protects the privacy of sensitive data as it traverses the Internet. Updates to TLS have significantly strengthened data privacy over the Internet with the introduction of perfect forward secrecy and stronger crypto ciphers in TLS 1.2 and TLS 1.3.
This article, based on Packet Detectives’ episode “ The case of the unknown TLS versions,” shows how you can use packet capture (via Endace) and Wireshark to discover the outdated & vulnerable devices that exist on your network In Hashing Out Cyber Security, Monthly Digest Weak encryption is a real risk to data privacy and security.
