SC-5(3): Detection / Monitoring
(Not part of any baseline)
- NIST Special Publication 800-53 Revision 5:
- SC-5(3): Detection and Monitoring
- Employs [Assignment: organization-defined monitoring tools] to detect indicators of denial of service attacks against the information system; and
- Monitors [Assignment: organization-defined information system resources] to determine if sufficient resources exist to prevent effective denial of service attacks.
Organizations consider utilization and capacity of information system resources when managing risk from denial of service due to malicious attacks. Denial of service attacks can originate from external or internal sources. Information system resources sensitive to denial of service include, for example, physical disk storage, memory, and CPU cycles. Common safeguards to prevent denial of service attacks related to storage utilization and capacity include, for example, instituting disk quotas, configuring information systems to automatically alert administrators when specific storage capacity thresholds are reached, using file compression technologies to maximize available storage space, and imposing separate partitions for system and user data.
