Entry level network engineers can enhance their networking knowledge by learning CCNA. This is an IT certification course from Cisco, one of the world’s top IT companies, and it stands for Cisco Certified Network Associate. This certification program from Cisco helps to maximise investment in foundational networking knowledge and also increase value of the employer’s network. CCNA Routing and Switching certifies the knowledge to install, configure, operate as well as troubleshoot medium sized networks.


Network device security 

One of the important steps to be taken by an administrator is to secure the availability of administrative access to devices such as switches, servers, firewalls and others. The CCNA Security curriculum explains in detail the various methods to secure access to network devices. This curriculum covers CLI (Command Line Interface) along with GUI management tools such as Cisco Security Device Manager (SDM). The router is one of the main devices which requires Network security.

Requirement of Network device security

With large number of online systems in the world, the demand for Network security is ubiquitous. Both private and public sector organisations make use of it. CCNA security certification is recognised by the Committee on National Security Systems (CNSS) as well as the US National Security Agency (NSA). Therefore there is tremendous scope for brilliant and experienced network professionals.
