A network security engineer has a versatile job. The main task of a network security engineer is to plan, design, optimize, implement, audit, and troubleshoot the network security system to improve the efficiency of the organization. The network security job is to protect the network from threats and bugs that could attack the system and also from the existing dangers. Most importantly, they must make sure that the networking systems can bounce back or withstand any type of mishaps such as natural disasters and hacker attacks.

They should have a thorough knowledge and a multi-branched background that should include expertise from the fields of information technology, network and engineering, and information security. Thus, the network engineer education is not limited to just one field, but it has a multi-pronged approach.
