Common Vulnerabilities In TLS And How Cisco Addresses Them
In today’s digital landscape, secure communication is paramount for organizations as they strive to protect their sensitive data from cyber threats. However, even the most robust protocols like Transport Layer Security (TLS) are not immune to vulnerabilities. This section delves into the common vulnerabilities found in TLS and how Cisco addresses them to enhance network security.
One of the key vulnerabilities in TLS is known as the Padding Oracle Attack, where an attacker can decrypt sensitive information by manipulating the padding in TLS cipher blocks. To counter this, Cisco has implemented various countermeasures like adding randomization to the handshake process and enforcing strict padding checks.
Another concern is Server Name Indication (SNI) leakage, which occurs when a malicious actor intercepts the SNI information, compromising the user’s privacy and anonymity. Cisco tackles this vulnerability by introducing Transport Layer Security for Applications (TLSA) and Domain Name System Security Extensions (DNSSEC) to encrypt SNI data.
