U.S. Department of Health and Human Services

Significant changes are changes in the IT system or software applications that:

Alter mission

Alter operating environment

Alter basic vulnerabilities of the IT system

Change protection requirements

Produce the occurrence of a significant violation or incident

Produce audit/evaluation findings that identify significant unmitigated risks

Many significant changes are driven by Agency and National Security policies and regulations such as FISMA and Department of Homeland Security. These changes tell us how we must conduct business such as acquisition, protection levels, and risk assessments.

The change can occur to:

Threats (a new adversary or a new virus, for example);

Vulnerabilities (a recently discovered “hole” in the programming); or

Technological Environment (a new hardware/software, a new storage area network (SAN)).
