SV-3046r1_ruleThe IAO/NSO will ensure that security alarms are set up within the managed network's framework. At a minimum, these will include the following: - Integrity Violation: Indicates that network contents or objects have been illegally modified, deleted, or added. - Operational Violation: Indicates that a desired object or service could not be used. - Physical Violation: Indicates that a physical part of the network (such as a cable) has been damaged or modified without authorization. - Security Mechanism Violation: Indicates that the network's security system has been compromised or breached. - Time Domain Violation: Indicates that an event has happened outside its allowed or typical time slot.
SV-3047r1_ruleThe IAO/NSO will ensure that alarms are categorized by severity using the following guidelines: - Critical and major alarms are given when a condition that affects service has arisen. For a critical alarm, steps must be taken immediately in order to restore the service that has been lost completely. - A major alarm indicates that steps must be taken as soon as possible because the affected service has degraded drastically and is in danger of being lost completely. - A minor alarm indicates a problem that does not yet affect service, but may do so if the problem is not corrected. - A warning alarm is used to signal a potential problem that may affect service. - An indeterminate alarm is one that requires human intervention to decide its severity.
