Cryptography, PKI, and Cloud Security for Security+ Prep

Securing modern digital infrastructure requires a deep understanding of how data is protected both in transit and at rest. This text-based course guides you through the core cryptographic, identity, and cloud security concepts aligned with industry-standard security certifications. You will transition from understanding basic security definitions to confidently analyzing encryption algorithms, managing public key infrastructure, and securing virtualized cloud environments. What you'll learn: Understand fundamental cryptographic concepts, including symmetric and asymmetric encryption, hashing, and digital signatures; Configure and manage Public Key Infrastructure components, certificates, and trust pathways; Analyze secure communication protocols used to protect data across networks and cloud services; Evaluate cloud deployment models, virtualization security, and shared responsibility frameworks; Apply modern zero-trust principles and secure access controls to cloud-based resources; Identify common cryptographic attacks and implement industry-standard mitigation strategies. The course begins with foundational terminology and cryptographic mathematics, progressing systematically through certificate management, secure network protocols, and modern cloud security architectures. This course is designed for aspiring IT security professionals and beginners preparing for security certification exams, with no prior cryptography experience required.
