Automated Inspection items for NIST SP 800-53 AC-7 assessment.

Automated Inspection items are efficient enough that they can usually be part of a CA-7 Continuous Monitoring program on a daily (or in some cases hourly) basis, simultaneously meeting the requirements of RA-5 Vulnerability Scanning. While NIST 800-53 allows Continuous Monitoring results to be used for CA-2 Security Assessments and CA-4 Security Certification, a separate run using the same automated Inspection items in combination with more laborious items for CA-2 and CA-4 adds no significant burden.

Depending on FIPS 199 impact level and whether the Industrial Control Systems (ICS/SCADA) subset of 800-53 is chosen,  LJK/Security™ starter templates provide automated Inspection items as follows:

NIST SP 800-53 R2 AC-7
Description  Automated Tests
System parameter LGI_BRK_LIM has a value no higher than 5.
(VMS,LGIBRKLIM,ABSOLUTHI)
System parameter LGI_BRK_TMO is set to a value of 300 seconds.
(VMS,LGIBRKTMO,ABSOLUTHI)
(VMS,LGIBRKTMO,ABSOLUTLO)
System parameter LGI_HID_TIM is set between 600 and 3600.
(VMS,LGIHIDTIM,ABSOLUTLO)
NIST SP 800-53 R2 AC-7(1)
Description  Automated Tests
System parameter LGI_BRK_DISUSER is enabled.
(VMS,BRKDISUSER,PROHIBITED)
(VMS,BRKDISUSER,REQUIRED)

Manual Inspection items for NIST SP 800-53 AC-7 assessment.

Manual Inspection items are useful mainly for CA-2 Security Assessments and CA-4 Security Certification. For most environments they are too laborious to include in CA-7 Continuous Monitoring.

Depending on FIPS 199 impact level and whether the Industrial Control Systems (ICS/SCADA) subset of 800-53 is chosen,  LJK/Security™ starter templates provide Manual Inspection items in the following groups:

Determination Statement Number Group Names

Manual Invasive Testing items for NIST SP 800-53 AC-7 assessment.

Manual Invasive Testing items are useful mainly for CA-2 Security Assessments and CA-4 Security Certification. For most environments they are too laborious to include in CA-7 Continuous Monitoring. The level of effort required and the degree of invasiveness are so high (in most cases making up for lack of Common Criteria evaluation) that arrangement as a Common Control is almost always a requirement for execution.

Depending on FIPS 199 impact level and whether the Industrial Control Systems (ICS/SCADA) subset of 800-53 is chosen,  LJK/Security™ starter templates provide Manual Invasive Testing items in the following groups:

Determination Statement Number Group Names
NIST SP 800-53 R2 AC-7
TEST_VMS_LOGFAIL
NIST SP 800-53 R2 AC-7(1)
TEST_VMS_BRKDISUSER

Descriptions above apply to  LJK/Security™ Version 3.0.

The notation NIST SP 800-53 above refers in particular to NIST Special Publication 800-53 Revision 2.

Those NIST Special Publications specify security standards in support of FISMA for US Federal Government civil activities.
