Securing Networks with PKI: Public Key Infrastructure Essentials

In an era of constant cyber threats, securing data in transit and validating digital identities is paramount for any organization. Public Key Infrastructure (PKI) serves as the trust foundation for modern network security, ensuring confidentiality and integrity across systems. This text-based course guides you through the core concepts of PKI and teaches you how to implement robust security controls to protect your network environment. What you'll learn: - Understand the fundamental principles of asymmetric cryptography, certificate authorities, and trust chains. - Configure secure web traffic by implementing and managing HTTPS certificates. - Secure domain name resolution using DNSSEC to prevent spoofing and tampering. - Implement Name Resolution Policy Tables (NRPT) to enforce secure DNS lookups. - Protect sensitive data at rest using the Encrypting File System (EFS). - Apply zero-trust network principles and modern certificate management practices to your security architecture. You will start by mastering foundational cryptographic concepts and key terminology before reading through step-by-step configuration scenarios for securing network services and data storage. This course is designed for junior system administrators, network engineers, and IT professionals looking to build a strong foundation in network security without needing advanced prior cryptographic knowledge.
