- Denial of Service (DoS) attacks, and how they target the availability pillar of the CIA triad by exhausting critical system resources.
- Network bandwidth exhaustion, where attackers flood infrastructure with massive traffic volumes (large or high-frequency packets) to overwhelm connectivity and block legitimate access.
- CPU and memory exhaustion, including:
- Fork bombs that rapidly spawn processes
- Exploiting inefficient code (e.g., poorly written algorithms or regex causing exponential resource usage)
- Storage-based attacks, such as:
- Zip bombs and XML expansion attacks that inflate small files into massive data, filling disk space and crashing systems
- Cloud resource and financial exhaustion, where attackers abuse auto-scaling environments to:
- Trigger excessive resource allocation
- Cause service shutdown due to budget limits or generate extreme operational costs
- Battery drain attacks, targeting mobile and IoT devices by forcing continuous activity, leading to:
- Rapid power depletion
- Potential long-term hardware damage
- Physical and accidental availability threats, recognizing that downtime can also result from:
- Environmental events (e.g., storms, power failures)
- Human error (e.g., spills, misconfigurations)
- Hardware damage or infrastructure disruption
