Looking Back at 2015 A number of new tactics proved 2015 was no exception to an active year defending against ever increasing security issues. Vendors found new and creative ways to provide vulnerabilities including the now popular man-in-the-middle (MitM) attacks. MitM as well as a host of other new vulnerabilities caused browsers to rethink their security requirements. This article gives a flashback of the exploits and industry changes from 2015 and looks ahead at the latest security requirements and how it impacts IT security teams.

Perfect Forward Secrecy

Recent revelations from Edward Snowden about pervasive government surveillance have led to many questions about the safety of communications using the SSL/TLS protocol. Such communications are generally safe from eavesdroppers, as long as certain precautions are observed. For example, configuring your web server to avoid using SSL2 and SSL3, favoring newer versions of TLS like TLS 1.2, selecting strong ciphersuites, etc. But even if your server is configured properly, you still must secure the private key associated with your SSL certificate.

They say the most complicated skill is to be simple; despite SSL and HTTPS having been around for a long time, they still are not as simple as they could be. One of the reasons for this is that the security industry is constantly learning more about how to design and build secure systems; as a result, the protocols and software used to secure online services need to continuously evolve to keep up with the latest risks.
