As of Dec 16, 2024 ITK's OpenSSF scores are the following:

Holistic security practices

| Category | Group | Metric | Score |

|  | 1 | CI-Tests | **10** |
|  | 1 | Fuzzing | **0** |
|  | 1 | SAST | **0** |
|  | 2 | CII-Best-Practices | **0** |
|  | 2 | Dependency-Update-Tool | **0** |
|  | 2 | License | **10** |
|  | 2 | Maintained | **10** |
|  | 2 | Security-Policy | **0** |

Holistic security practices

| Category | Metric | Score |

- [ ] CII-Best-Practices
- [ ] Dependency-Update-Tool
- [ ] Security-Policy
- [ ] Branch-Protection
- [ ] Dangerous-Workflow
- [ ] Packaging
- [ ] Pinned-Dependencies
- [x] Signed-Releases
- [ ] Token-Permissions

### Actual behavior

ITK scrores in OpenSSF have room for improvement.

### Versions

`master`

### Environment

Some items may not apply to ITK, and thus may need to be bypassed in the evaluation, and some others are maybe not being processed correctly (e.g. signed releases).
