👉 Defensive computing is an approach to cybersecurity that focuses on proactively identifying, preventing, and mitigating potential threats to an organization's information systems and data. It involves implementing a multi-layered security strategy that includes measures such as firewalls, intrusion detection systems, encryption, access controls, and regular security audits. The goal is to create a robust defense-in-depth model that not only protects against known vulnerabilities but also anticipates and adapts to emerging threats, ensuring the confidentiality, integrity, and availability of sensitive data. By continuously monitoring network traffic, user behavior, and system logs, defensive computing aims to detect anomalies and respond swiftly to potential security breaches, thereby minimizing the risk of data loss or system compromise.
