IT Security Specialist

Any computer connected to the Internet is vulnerable to cyber-attacks. Cyber security is the technique used to protect computers and networks from these types of intrusions and from criminal attack. Specialists in cybersecurity are among the most sought-after professionals in the tech sector, as business and governments seek to fight off an increasingly daring and ruthless group of global cybercriminals and hackers.

With some of the world’s biggest firms and banks as well as governments under constant fire of threats, skilled, clever and dedicated security specialists work in a field that demands a mix of artistry and technical expertise. They need to be one step ahead of the hackers and organised criminals at all times.
