Digital Certificate Management and PKI Fundamentals

Accidental certificate deletion or expiration can lead to widespread system outages and security vulnerabilities. This course provides the foundational knowledge necessary to handle digital certificates confidently, ensuring the secure operation of your infrastructure. Gain expertise in maintaining the critical trust relationships that underpin modern secure communication across the internet and internal networks. **What you'll learn:** * Understand the core architecture of Public Key Infrastructure (PKI), including Certificate Authorities (CAs) and the chain of trust. * Analyze the security and operational impact of certificate expiration, deletion, or compromise across various systems. * Learn standard procedures for generating, issuing, renewing, and securely revoking digital certificates using Certificate Revocation Lists (CRLs) and OCSP. * Practice essential backup and recovery methods for high-value root and intermediate CA keys and certificates to prevent catastrophic loss. * Apply best practices for secure key management and storage, including the basic role of Hardware Security Modules (HSMs). * Configure basic methods for automating certificate provisioning and lifecycle management to reduce manual errors and downtime. The course begins by defining core cryptographic concepts and PKI components before moving into practical certificate lifecycle management, recovery planning, and operational security procedures. This course is designed for absolute beginners interested in network security, system administration, or IT operations, requiring no prior experience with cryptography.
