si-3(8)

malicious code protection  | detect unauthorized commands

assessment objective:

Determine ifV:

si-3(8)[1]

the organization defines unauthorized operating system commands to be detected by the information system;

si-3(8)[2]

the organization defines information system hardware components for which organization-defined unauthorized operating system commands are to be detected through the kernel application programming interface;

si-3(8)[3]

the information system detects organization-defined unauthorized operating system commands through the kernel application programming interface at organization-defined information system hardware components, and does one or more of the following:

si-3(8)[3][a]

issues a warning;

si-3(8)[3][b]

audits the command execution; and/or

si-3(8)[3][c]

prevents the execution of the command.

potential assessment methods and objects:

Examine: [select from: System and information integrity policy; procedures addressing malicious code protection; information system design documentation; malicious code protection mechanisms; warning messages sent upon detection of unauthorized operating system command execution; information system configuration settings and associated documentation; information system audit records; other relevant documents or records].

Interview: [select from: System/network administrators; organizational personnel with information security responsibilities; system developers; organizational personnel installing, configuring, and/or maintaining the information system; organizational personnel with responsibility for malicious code protection].

Test: [select from: Automated mechanisms supporting and/or implementing malicious code protection capability;  automated mechanisms supporting and/or implementing detection of unauthorized operating system commands through the kernel application programming interface].
