Server Hardening Training & Certification (RH413)

Nowadays, security is an important and integral aspect of working process of any organisation, so much so that an organization cannot function without it. This is important when one is dealing with confidential and private data files. The security features can be improved by learning hardening skills offered by Techgrills. The Red Hat server hardening training course provides valuable guidance on managing and administering security updates and tracking them. One can also get an opportunity to learn about the management of software updates and their verification through this training program.

In working place, an employer needs to keep a watch on the websites accessed by the employees when the internet usage is liberal. Therefore one needs to put restriction upon certain websites at workplace to increase the productivity of the organisation. These restricted websites may include social networking sites, chatting zones etc.

Red Hat Certified server hardening training course is designed for users who have gained knowledge and experience into Red Hat Linux operating systems. The training course helps one improve in various domains of security issues like maintenance of security at workplace, authentication system for entry, system configuration, creating and managing system files, restricting the content through internet like websites, etc. to the system and auditing the system.

A brief outline of the said course is as given below.

• Tracking security updates and managing software updates

• Creating file systems by allocating file system layout and using the encryption

• Managing file systems by adjusting file system properties through security related criteria and file system attributes.

• Managing special permissions and file access controls

• Managing user accounts

• Configuring system logging and auditing

• Installing and managing central authentication system

• Controlling access to network services

For opting to this course, the candidate is required to have Red Hat Certified Engineer (RHCE) certification or Red Hat Certified Systems Administrator (RHCSA) certification or any other equivalent certification or experience. He is required to be proficient in advanced operations of Linux operating systems. This course will help the candidate to gain knowledge in advance security measures used in Linux operating systems.

Red Hat Certified server hardening training course is in big demand today as security is a key question in any organisation or set-up. In this competitive world, right from data security to controlling and restricting the web content in the system is of a big importance to any employer or owner of the company.
