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
