Cyber criminals try to find and attack government’s official sites, sites of armed forces organizations and other business organizations. They are the ones who stop sensitive information from getting leaked. In an organization cybersecurity expert matters a lot because he is the one who identifies complex issues and resolve them helping business to keep running smoothly.

Security Analyst

The first thing a cybersecurity expert does, he checks out the existing security plan and system and looks for all the vulnerabilities and loopholes in it. He analyzes things kike software, hardware and gives suitable suggestions about the changes that are needed to be done to make the security intact. This is the most important part when he starts his job. 

Security Developer

Another responsibility of a cybersecurity expert is to develop a security plan for company. He has already analyzed everything about the existing one. So, he develops cybersecurity system according to the needs. Every company needs a different type of security plan. Its hardware and software can differ as the requirements change. He might be building the system himself or he may lead a team, designing the security system.

Security Administrator

He installs the developed security system and applies all the settings to it. He looks for the changes or upgrade that is needed. Being the administrator he gets reported about everything related to the system and security. He is responsible and answerable to the company’s management. 


He analyzes the malware and viruses. He encrypts the information behind this malicious stuff to know its purpose. This helps in building a stronger security program for the system.
