Introduction

This chapter covers the fourth objective of Domain 1.0, Explain the Importance of Using Appropriate Cryptographic Solutions.

In the digital age, where data permeates every aspect of our lives, ensuring its security has become paramount. Cryptographic solutions have emerged as the stalwart guardians of this digital realm, shielding sensitive information from the myriad of threats it faces.

At the core lies the Public Key Infrastructure (PKI), a foundation of security comprising public and private keys, certificates, and key escrow mechanisms. Encryption, a cornerstone of information protection, comes in various forms, including full-disk, file, and database encryption, which are bolstered by tools such as Trusted Platform Modules (TPMs) and Hardware Security Modules (HSMs).

Beyond encryption, cryptographic techniques encompass obfuscation, hashing, digital signatures, and key management. These techniques serve to obscure, validate, and safeguard data from unauthorized...
