Penetration testing is a simulated cyberattack that helps organizations identify and fix security vulnerabilities before they can be exploited by malicious actors. It is a critical tool for cybersecurity, and it should be a regular part of any organization's security program. Penetration testing typically involves gathering information about the organization's network and systems, vulnerability scanning, exploitation, and reporting. It can be a valuable tool for improving an organization's cybersecurity posture, but it is important to note that it is not a silver bullet. It should be used in conjunction with other security measures, such as firewalls, intrusion detection systems, and employee training.

Secure containerized applications with Docker and Kubernetes. Use secure images, vulnerability scanning, isolation, RBAC, and runtime security for robust protection.
