Cyber defense refers to the strategies and measures taken to protect computer systems, networks, and data from cyber attacks. This includes identifying vulnerabilities, implementing security protocols, and monitoring for suspicious activities. Organizations use various tools and techniques to safeguard their information, ensuring that sensitive data remains secure from unauthorized access. Effective cyber defense involves a combination of technology, processes, and trained personnel. It often includes practices such as firewalls, encryption, and regular software updates. Additionally, organizations may conduct penetration testing to assess their security posture and improve their defenses against potential threats.
