CVE-2023-20155

Limiting concurrent sessions directly prevents uncontrolled resource consumption by capping the number of active sessions per user or account.

Contingency plan testing includes resource exhaustion scenarios to verify recovery, making it harder for attackers to sustain exploits that cause uncontrolled consumption.

Updated contingency plans include current procedures to detect, contain, and recover from resource exhaustion, limiting an attacker's ability to sustain impact from uncontrolled consumption.

Alternate site allows resumption of operations if resource exhaustion at the primary site is exploited to cause unavailability.

Alternate telecommunications services enable resumption of essential functions when primary services become unavailable due to uncontrolled resource consumption.

Planning and coordination of security activities (scans, tests, maintenance) directly imposes scheduling and throttling that prevents those activities from producing uncontrolled resource consumption.

Performance metrics and monitoring inherently track resource consumption patterns, making uncontrolled consumption easier to detect and mitigate.

Terminating idle connections bounds resource consumption that would otherwise allow uncontrolled accumulation of open sessions.

Continuous monitoring of computing resources can detect resource exhaustion but does not itself enforce allocation limits.

Resilience mechanisms such as avoiding single points of failure indirectly reduce impact of resource exhaustion.

Hardened configuration baselines can include resource quotas and limits that constrain consumption.

Pre-agreed severity-based prioritization and resource allocation during incident triage reduce the likelihood that an attacker-induced resource exhaustion will overwhelm the organization before corrective action is taken.

Business-continuity plans that include resource-management controls reduce the likelihood that an attacker can trigger uncontrolled resource consumption by forcing the system into a degraded or fallback state.

Defining RTOs and capacity requirements for ICT services during business-impact analysis forces organizations to provision sufficient resources and throttling mechanisms, reducing the likelihood that an attacker can induce denial-of-service through uncontrolled resource consumption.

Early notification of anomalous resource consumption or system malfunctions enables throttling or isolation before availability is lost.
