Why Your TLS Connection May Not be as Secure as You Think
The Transport Layer Security (TLS) cryptographic protocol is the backbone of encryption on the Internet. It prevents eavesdropping, tampering, and message forgery between two communicating network endpoints.
TLS secures many types of Internet communication, including web browsing, email, instant messaging, and voice over IP (VoIP). However, a misconfiguration in TLS can open the doors to multiple vulnerabilities.
This blog post explores the risks around TLS misconfigurations, general problems with TLS that network security engineers face, and how one solution can solve all your problems.
TLS is the successor to the Secure Sockets Layer (SSL) protocol. The TLS protocol provides security for transmission over computer networks such as the Internet. Web browsers and web servers commonly use TLS/SSL.
The protocol guarantees privacy between communicating applications, data integrity, and authenticity of the communication partners. TLS can authenticate a server, encrypt data, and ensure a message was not altered during its transmission.
While TLS offers much better security than good old SSL, it faces its fair share of malicious attempts by bad guys trying to get to organizations’ sensitive data. Therefore, it’s important to figure out how the bad guys use TLS to drop malware.
It goes without saying that TLS is not responsible for securing your data at its destination; instead, it just guarantees safe passage for your data over the Internet, ensuring that the data in transit can’t be eavesdropped upon or modified
