    analyst='senior_analyst'
)

# Add remediation actions
# ... (use remediation utilities as shown above)

# Track progress
playbook.complete_action(action.id, 'Successfully removed malware')
playbook.verify_action(action.id, 'Verified clean via EDR scan')

# Generate reports
print(playbook.generate_report())
print(playbook.generate_recovery_certification())

# Export for documentation
print(playbook.to_json())

Configuration

Environment Variables

Variable	Description	Required	Default
`REMEDIATION_LOG_PATH`	Log file path	No	`./remediation.log`
`BACKUP_PATH`	Default backup location	No	`./backups`
`BASELINE_PATH`	Security baseline location	No	`./baselines`

Verification Settings

All remediation actions include verification steps:

python

# Get verification status
if action.verification_required:
    print(action.verification_steps)

# Mark verification complete
playbook.verify_action(action.id, 'Verified by EDR scan')

Limitations

No Direct Execution: Generates commands/procedures, does not execute directly
Requires Clean Media: System rebuilds require verified clean installation media
Backup Dependencies: Data restoration requires valid, clean backups
Time Requirements: Full remediation may take hours to days

Troubleshooting

Remediation Verification Failed

Problem: Post-remediation verification shows issues

Solution: Re-run targeted remediation:

python

# Identify remaining issues
remaining = action.get_verification_failures()
print(f"Remaining issues: {remaining}")

# Create follow-up action
follow_up = malware.remove_malware(hostname, remaining_artifacts)

Backup Restoration Failed

Problem: Backup restoration incomplete or corrupt

Solution: Try alternative recovery sources:

python

action = data.backup_restoration(
    target_system='SERVER-01',
    backup_source='alternative_backup',
    restore_type='incremental',
    verify_backup_integrity=True
)
