Penetration Testing and ISO 27001 – Securing your ISMS 

As part of your ISO 27001 risk assessment, you must identify information security risks within the scope of your ISMS (information security management system). Penetration testing is one of the best ways to gain accurate, detailed information about those risks.

Penetration testing establishes whether the security in place to protect networks, applications and other key systems is adequate and functioning correctly. The threats and vulnerabilities identified will form a key input of your risk assessment, while the recommended remedial actions will inform your selection of controls.
