Don't miss the event on " Network Security using IPSec and PKI " which is scheduled for the day October 22, 2012 (Monday) will start to 15:00 Time of Brasilia with duration of 1:0 . Description: The technique of server isolation using Internet Protocol security (IPSec) is an alternative to achieve logical isolation, protecting network communications, and as a result, the defense-in-depth architecture. Physical and logical isolation are category options technology, adopted by this architecture, to provide security in computer systems and networks. Will be presented a brief script to extend the server isolation technique based on the Internet Protocol security (IPSec), in networks with mixed operating systems and that, in addition, have migrated to IPv6. For the integration of heterogeneous systems, proposed a combination of the OpenSSL software and IPSec Tools in addition to the operating systems based on free software and the creation of a public k
