Update all third-party software such as browsers and plugins
IT attacks target all the software layers equally. As these attacks interact with third-party software such as browsers, middleware or program extensions it is important for this software to be quickly corrected following the discovery of significant faults or bugs.
Third-party software is also a target of attacks, which will be all the more pernicious if patches of this software are not systematically installed. Browsers and middleware (Flash, SilverLight, Java, e-ID, .NET etc.) are common ways of exploiting end users.
