De Paul College offers a Certificate Programme in Cyber Security and Ethical Hacking. Cyber Security is the practice of defending computers, servers, mobile devices, electronic systems, networks and data from malicious attacks. Ethical hacking is part of Cyber Security, which mainly deals with finding vulnerabilities in a system and solving them before any malicious or black-hat hacker exploits them. It is the process of testing and validating the system to discover the weaknesses present in it and inform the organization about all those weaknesses.
