Key management refers to the process of handling cryptographic keys in a secure manner. This includes the generation, distribution, storage, and destruction of keys used for encrypting and decrypting data. Proper key management is essential to ensure the confidentiality and integrity of sensitive information. Effective key management practices help organizations protect their data from unauthorized access and cyber threats. It often involves using tools and protocols to automate key lifecycle management, ensuring that keys are rotated regularly and that access is restricted to authorized personnel only. This is crucial for maintaining security in systems that rely on encryption, such as SSL/TLS and VPNs.
