At a Glance: Penetration Testing

Penetration testing is the practice of performing a software attack on a computer system or network with the goal of discovering weaknesses, exploits, and vulnerabilities. If you’re looking to improve network security or proactively seek to prevent exploits, you’ll need the help of a penetration testing specialist to keep your systems one step ahead of people looking for an easy way into your system.
A penetration testing specialist can design and run tests to assess the ability of your security systems to guard against potential attack vectors. To do this, they may set up either a white box (a target filled with actual system information) or a black box (a dummy file) as a target. The penetration tester then identifies potential exploits and designs attack vectors to potentially breach the system. The penetration tester can also design attacks that can expose other exploits that have yet to be predicted. Penetration testing specialists on Upwork can help you improve your network’s defenses by designing, building, and executing penetration tests that reveal vulnerabilities.
