Linux Security
Course Description
The main goal of this course is to provide you with an understanding of networking, specifically Linux networking and security. You will learn how to set up a Linux server and how to configure name resolution and dial-in network access using the X window system. You will also be exposed to file sharing technologies such as the Network File System (NFS), NetWare’s NCP file sharing, and the File Transfer Protocol (FTP). Finally, you will be introduced to network security, including concepts such as firewalls, encryption, and network intrusion detection. In order to reinforce the material, the course provides a range of laboratory and hands-on assignments that puts you in the role of a problem solver, requiring you to apply concepts presented in the modules to situations that might occur in a real-life work environment.
Who Should Attend
Network server administrators, firewall administrators, systems administrators, application developers, and IT security officers.
Duration:
3 days (9:00 – 5:00)
Certification
The Linux Security 212-77 exam will be conducted on the last day of training. Students need to pass the online Prometric exam to receive the CEP certification.
