A Protection Mechanism is a mechanism that can safeguard system resources, data assets, or operational processes from undesired events or unauthorized actions.
- AKA: Safety Mechanism, Protective System, Safeguard Mechanism.
- Context:
- It can typically monitor System State through detection components.
- It can typically enforce Protection Policy using control mechanisms.
- It can typically respond to Threat Events via intervention actions.
- It can typically maintain Protection Boundary between protected resources and potential threats.
- It can typically implement Risk Mitigation Strategy based on threat assessment models.
- ...
- It can often provide Protection Logging for security audit purposes.
- It can often adapt Protection Levels based on threat severity assessments.
- It can often coordinate with Related Protection Systems for comprehensive coverage.
- It can often balance Security Requirements with usability considerations.
- ...
- It can range from being a Simple Protection Mechanism to being a Complex Protection Mechanism, depending on its protection sophistication level.
- It can range from being a Reactive Protection Mechanism to being a Proactive Protection Mechanism, depending on its threat response timing.
- It can range from being a Single-Layer Protection Mechanism to being a Multi-Layer Protection Mechanism, depending on its defense depth.
- ...
- It can integrate with Monitoring Systems for threat detection capability.
- It can support Recovery Processes through incident response procedures.
- It can enable Compliance Requirements via regulatory standard adherence.

- Example(s):
- Physical Protection Mechanisms, such as:
- Mechanical Protection Devices, such as:
- Safety Valve preventing pressure vessel explosions.
- Circuit Breaker interrupting electrical fault currents.
- Structural Protection Systems, such as:
- Firewall (Physical) containing fire spread.
- Flood Barrier preventing water damage.
- Mechanical Protection Devices, such as:
- Digital Protection Mechanisms, such as:
- Access Control Mechanisms, such as:
- Authentication System verifying user identity.
- Authorization System enforcing permission rules.
- Data Protection Mechanisms, such as:
- Encryption Mechanism securing data confidentiality.
- Overwrite Protection Mechanism preventing unintended data overwrites.
- Access Control Mechanisms, such as:
- Process Protection Mechanisms, such as:
- Error Handling Mechanisms, such as:
- Exception Handler managing runtime errors.
- Failover System maintaining service availability.
- Resource Protection Mechanisms, such as:
- Memory Protection preventing unauthorized memory access.
- Rate Limiter controlling resource consumption rate.
- Error Handling Mechanisms, such as:
- ...
- Physical Protection Mechanisms, such as:
- Counter-Example(s):
- Monitoring System, which observes system behavior without actively preventing undesired actions.
- Logging System, which records system events without implementing protective measures.
- Alert System, which notifies about potential issues without taking protective actions.
- Analysis System, which evaluates system state without enforcing protection policy.
