Description
|| Unofficial Course ||

This comprehensive course onPublic Key Infrastructure (PKI)is designed to equip learners with a deep and practical understanding of how digital trust is established, managed, and maintained across modern IT systems. Starting from foundational concepts, the course covers the core principles, components, and operations that make PKI a cornerstone of cybersecurity today. You’ll learn whatPKIis, why it matters, and how it supports secure communications, identity verification, and data integrity in a variety of real-world scenarios.

Throughout the course, you will explore the architectural building blocks of PKI, including certificate authorities (CAs), registration authorities (RAs), digital certificates, and cryptographic key pairs. You will understand how trust is built through chains of certificates, and how systems rely on this trust to enable secure web access, encrypted emails, authenticated VPNs, and signed code. The lifecycle of a certificate—from creation and validation to renewal and revocation—is explained in detail, along with secure key storage and management practices using tools like Hardware Security Modules (HSMs).

You’ll dive into how PKI is operated and governed within an enterprise, including the creation of certificate policies, trust models like hierarchical and mesh, and techniques for automating certificate issuance and renewal using protocols such as SCEP and ACME. As modern infrastructures scale, you’ll also gain insights into designing PKI environments for high availability and disaster recovery.

The course emphasizes hands-on application of PKI across various domains including SSL/TLS for web security, S/MIME for secure email, code signing for software integrity, and certificate-based network access through technologies like 802.1X and EAP-TLS. Governance, compliance, and auditing are also key focus areas, with coverage of international standards, industry best practices, and strategies for risk mitigation and forensic readiness.

To ensure you stay ahead of evolving technology landscapes, the course concludes with forward-looking topics like decentralized PKI models, quantum-resistant cryptography, and PKI implementation in resource-constrained environments such as IoT and embedded systems.

Whether you're a cybersecurity professional, IT administrator, developer, or technical manager, this course will provide you with the skills and knowledge needed to confidently design, implement, andmanage PKI systemsthat support secure digital operations in any organization.
