Enabling Show Wi-Fi status in menu bar is a security awareness method that helps mitigate public area wireless exploits by making the user aware of their wireless connectivity status.
Library Validation protects processes from loading arbitrary libraries, root from becoming more powerful. Running without Library Validation on a production system runs the risk of the modification of system binaries or code injection of system processes that would otherwise be protected by Library Validation.
A session lock is a temporary action taken when a user stops work and moves away from the immediate physical vicinity of the information system but does not want to log out because of the temporary nature of the absence. The session lock is implemented at the point where session activity can be determined. Rather than be forced to wait for a period of time to expire before the user session can be ...
Inaccurate time stamps make it more difficult to correlate events and can lead to an inaccurate analysis. Determining the correct time a particular event occurred on a system is critical when conducting forensic analysis and investigating system events. Sources outside of the configured acceptable allowance (drift) may be inaccurate. Synchronizing internal information system clocks provides unifor ...
Unapproved mechanisms for authentication to the cryptographic module are not verified, and therefore cannot be relied upon to provide confidentiality or integrity, resulting in the compromise of DoD data. Operating systems using encryption are required to use FIPS-compliant mechanisms for authenticating to cryptographic modules. The implementation of OpenSSH that is included with macOS does not ut ...
The audit service should shut down the computer if it is unable to audit system events. Once audit failure occurs, user and system activity is no longer recorded and malicious activity could go undetected. Audit processing failures include software/hardware errors, failures in the audit capturing mechanisms, and audit storage capacity being reached or exceeded. Responses to audit failure depend on ...
It is detrimental for operating systems to provide, or install by default, functionality exceeding requirements or mission objectives. These unnecessary capabilities or services are often overlooked and therefore may remain unsecured. They increase the risk to the platform by providing additional attack vectors. Operating systems are capable of providing a wide variety of functions and services. S ...
Any changes to the hardware, software, and/or firmware components of the information system and/or application can potentially have significant effects on the overall security of the system. Accordingly, software defined by the organization as critical must be signed with a certificate that is recognized and approved by the organization.
