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
