Discussion

FailureSecurity flaws with software applications are discovered daily. Vendors are constantly updating and patching their products to installaddress newly discovered security vulnerabilities. Organizations (including any contractor to the mostorganization) currentare Exchangerequired to promptly install security-relevant software updates (e.g., patches, service packpacks, leavesand hot fixes). Flaws discovered during security assessments, continuous monitoring, incident response activities, or information system error handling must also be addressed expeditiously. Organization-defined time periods for updating security-relevant software may vary based on a variety of factors including, for example, the security category of the information system vulnerableor the criticality of the update (i.e., severity of the vulnerability related to exploitationthe discovered flaw). This Currentrequirement servicewill packsapply correctto knownsoftware securitypatch management solutions used to install patches across the enclave and also to applications themselves that are not part of that patch management solution. For example, many browsers today provide the capability to install their own patch software. Patch criticality, as well as system vulnerabilitiescriticality will vary. Therefore, the tactical situations regarding the patch management process will also vary. This means that the time period used must be a configurable parameter. Time frames for application of security-relevant software updates may be dependent upon the Information Assurance Vulnerability Management (IAVM) process. The application will be configured to check for and install security-relevant software updates within an identified time period from the availability of the update. The specific time period will be defined by an authoritative source (e.g., IAVM, CTOs, DTMs, and STIGs).
