Cheat Sheet

  1. Full Disk Encryption Fundamentals -

    Full disk encryption protects data at rest by automatically encrypting every bit on a storage device, making files unreadable without proper authentication. Tools like Microsoft BitLocker and Apple FileVault use AES-256, as endorsed by NIST SP 800-111, to guard against data breaches. Think "all-or-nothing encryption" to remember that the entire disk is secured, not just individual folders.

  2. Core Encryption Algorithms -

    AES-256 is the industry gold standard for disk encryption, offering a strong balance between security and performance. According to NIST and academic research, its symmetric key structure makes both encryption and decryption efficient without sacrificing protection. Mnemonic trick: "A"dvanced "E"ncryption "S"tands at 256 bits for top-tier defense.

  3. Effective Key Management Strategies -

    Secure key storage is crucial - using hardware-based modules like TPMs or HSMs keeps keys separate from encrypted data, minimizing exposure. Best practices from the SANS Institute recommend multi-factor authentication combined with periodic key rotation to thwart unauthorized access. Remember the phrase "Keys off-site, peace of mind inside."

  4. Regulatory and Compliance Requirements -

    Many regulations, including GDPR and HIPAA, mandate disk encryption to protect sensitive information and avoid hefty fines. The IT Governance Institute and ISO/IEC 27001 outline controls requiring encryption as part of a robust data security framework. Tip: Map full disk encryption to compliance checklists to ensure you tick every box.

  5. Weighing Performance and Usability -

    While full disk encryption benefits data security principles, it can introduce slight performance overhead - especially on older hardware. Modern CPUs often include built-in AES instructions to accelerate encryption with minimal slowdowns, as documented by Intel and AMD white papers. You got this: balance security and speed by enabling hardware acceleration where available.
