    Study Notes

    Data Security

    • A combination of prevention strategies is required to guard data
    • Strong encryption should be used for data storage
    • Secure deletion of sensitive data is also necessary
    • Data should be overwritten with random bits to ensure proper deletion
    • Defense-in-Depth is a comprehensive approach that uses multiple solutions to achieve a security goal
    • Risks, threats, and vulnerabilities are intertwined

    Authentication

    • A secret passphrase or PIN is a well-known form of authentication
    • A single-factor cryptographic device uses embedded cryptographic keys and does not require a second factor of authentication
    • A multi-factor software cryptographic authenticator is a cryptographic key stored on disk that requires activation through a second factor of authentication

    Data Loss

    • Unintentional data deletion is a major cause of data loss
    • Intentional malware attacks are also a contributing factor

    Data Loss Prevention

    • Redundancy and backups are technical measures that can prevent data loss
    • Access control is a combination of strategic and technical measures that can reduce the risk of accidental deletion
    • Apple takes a controlled end-to-end hardware and software distribution model approach to security with its iOS platform
    • Apple iOS is the most restrictive of the two major platforms, a necessity for the delivery of a seamless user experience
    • Apple forbids mobile operators from introducing software on the device
    • Mobile device management systems can improve overall security by applying specific rules
    • Remote wiping methods exist for lost devices

    Malware Delivery

    • Third-party application stores and drive-by downloads are common delivery methods for malware
    • Malware can be designed to target iOS and/or Android
