Supports all activities associated with the maintenance of in-house designed software applications. The overall accountability rating for this information classification is Low.
Confidentiality level = Low
The confidentiality impact level is the effect of unauthorized disclosure of system maintenance information on the ability of responsible entities to maintain in-house designed software applications. In most cases, system maintenance information is not particularly sensitive and is distributed to the users. In general, disclosure of system maintenance information is likely to result in only limited adverse effects on the confidentiality of system information and processes.
Integrity level = Moderate
The integrity impact level is based on the specific mission and the data supporting that mission, not on the time required to detect the modification or destruction of information. The consequences of unauthorized modification or destruction of system maintenance information can be particularly serious because specific modifications to system changes can be difficult to identify.
Known mitigating factors toward changing the integrity level
The consequences of undetected or unauthorized modification or destruction of system maintenance information may depend on the maximum aggregate sensitivity and criticality of the information and processes associated with the system. The recommended integrity impact level can range from low to high to trade secret information (outside the scope of this guideline).
Availability level = Low
The availability impact level is based on the specific mission and the data supporting that mission, not on the time required to reestablish access to maintenance information. Functions and processes supported by most maintenance information are not time-critical. That is, temporary disruption of access to maintenance information will usually have only a limited adverse effect on organizational operations (including mission functions and public confidence in the organization), organizational assets, or individuals.
