Dražen Pranić, Zlatan Morić, Zdravko Kunić


Practical cryptography represents one of the most important aspects of information security. One of the most important elements of cryptog-raphy is Secure Sockets Layer (SSL) protocol, which is the most widely deployed security protocol, used today. Unfortunately SSL protocol is constantly exposed to various threats and vulnerabilities. Heartbleed, POODLE, FREAK are the most notorious SSL bugs in recent period. Many studies have shown that in the SSL implementation of SSL there are many challenges. The focus of this paper is placed on how the leading Croatian companies in the private and public sectors cope with these challenges. From this research it is evident that private companies have better SSL implementation although there are some challenges for both sectors for managing SSL configurations.
