Not everyone is vulnerable to the potential attack vector that researchers from INRIA, a French research institute, and Microsoft disclosed recently. In order to be vulnerable, the computer or server must support a class of deliberately weak export cipher suites. Support for these weak algorithms has remained in many implementations, however they are typically disabled by default. Nevertheless, the researchers discovered that several implementations incorrectly allow the message sequence of export ciphersuites to be used even if a non-export ciphersuite was nogotiated.

If you are building a secure computer, then the best approach is to never connect it to the internet. If the operating system on this computer is Windows, then you will have to activate it before you will be able to use it. This article explains how you can activate it by phone.

You may have heard of "Heartbleed", a flaw in OpenSSL that could allow the theft of data normally protected by SSL/TLS encryption.

It is possible to scan for the presence of this vulnerability using different methods.
