| Description |
| An example is a firewall that blocks all traffic rather than allowing all traffic when a firewall component fails (e.g., fail closed and do not forward traffic). This prevents an attacker from forcing a failure of the system to obtain access. Abort refers to stopping a program or function before it has finished naturally. The term abort refers to both requested and unexpected terminations. |
