UNIX/Linux – Security, Secure Communication and Cryptography

The course is designed for network administrators and network server administrators who use OS UNIX and who would like to learn to make the communication of these servers with their surroundings secure.

The participants will learn basic principles of cryptography and encryption in the computer security field. They will also learn how to implement PGP (GnuPG), SSL systems, etc.

Good knowledge of OS UNIX

GOPAS study materials
