# Validating Backup Integrity For Recovery

## Overview

Cybersecurity skill for validating backup integrity for recovery. Follows industry best practices and security standards.

## When to Use
**Trigger phrases:**
- "validating backup integrity for recovery"
- "Validate backup integrity through cryptographic hash verification, automated res"


Use this skill when:
- Verifying backup integrity before relying on backups for ransomware recovery
- Building automated backup validation pipelines that run after each backup job
- Auditing backup infrastructure to confirm recoverability for compliance (SOC 2, ISO 27001, NIST CSF RC.RP-03)
- Detecting silent data corruption (bit rot) in backup storage before a disaster occurs
- Validating that immutable or air-gapped backups have not been tampered with

**Do not use** for initial backup configuration or scheduling. This skill focuses on post-backup validation.


## When NOT to Use

- When you lack proper authorization for testing
- For production systems without change management
- When the task requires legal or compliance expertise beyond technical scope


## Prerequisites

- Access to backup storage (local, NAS, S3, Azure Blob, GCS)
- Python 3.9+ with `hashlib` (standard library)
- Backup manifests or baseline hash files for comparison
- Isolated restore environment for restore testing
- Backup tool CLI access (restic, borgbackup, rclone, or vendor-specific)

## Workflow

```python
# Example: IOC detection
import re

IOC_PATTERNS = {
    "ip": r"\b(?:\d{1,3}\.){3}\d{1,3}\b",
    "domain": r"\b[a-z0-9-]+\.[a-z]{2,}\b",
    "hash_md5": r"\b[a-f0-9]{32}\b",
    "hash_sha256": r"\b[a-f0-9]{64}\b",
}

def extract_iocs(text: str) -> dict:
    return {k: re.findall(v, text) for k, v in IOC_PATTERNS.items()}
```

1. **Define Objectives** — Clarify the goals and scope for backup integrity.
2. **Gather Resources** — Collect tools, data, and access needed for backup integrity.
3. **Execute Process** — Carry out backup integrity operations methodically.
4. **Verify Quality** — Check results against acceptance criteria.
5. **Document Outcomes** — Record findings, decisions, and next steps.

## Tools

- **recovery** — Primary tool for this skill
- **Analysis Platform** — Data processing and visualization
- **Collaboration Tools** — Team coordination and knowledge sharing


## Process

1. **Prepare** — Gather requirements, verify prerequisites, set up environment
1. **Execute** — Run validating backup integrity for recovery workflow with configured parameters
1. **Verify** — Validate output meets requirements, document results

## Verification

- [ ] All backup integrity procedures executed completely and documented
- [ ] Findings validated against multiple data sources
- [ ] False positives identified and filtered
- [ ] Results documented with evidence and timestamps
- [ ] Recommendations provided with risk-based prioritization

## Anti-Rationalization Table

| Rationalization | Reality |
|---|---|
| "We are too small to be targeted" | Automated attacks target everyone. Size does not matter. |
| "Security slows us down" | A breach slows you down 100x more. Build security in from the start. |
| "We will fix it after launch" | Vulnerabilities in production are exploited within hours. Fix before deploy. |
