Penetration Testing Jobs

Penetration Testing, or “pentesting” for short, is a valuable service for businesses and organizations of all sizes. It involves trying to access a system, website, or service illegally in order to expose any vulnerabilities that hackers can exploit. This allows IT departments and the people that protect the organization’s data to see those security issues before anyone malicious does. A Penetration Tester can help an organization keep their systems securely running by tackling any issues they discover while testing their systems.

  • Evaluating networks and services for common exploits that can easily be addressed
  • Exploring custom software for any issues prior to release
  • Securing voice counter-parties with careful auditing of cloud functions

    I want to stand up a small-scale lab at home where I can safely probe for weaknesses in both Windows and Linux machines. The main goal is to reproduce the kinds of flaws that appear on systems that have missed patches or are running outdated services, then verify that I can detect them.

Testing focus I plan to sta...
