# API Reference: Cloud Incident Response Agent
|
|
|
|
## Overview
|
|
|
|
Automates AWS cloud incident response: disables compromised access keys, attaches deny-all policies, isolates EC2 instances, captures EBS snapshots for forensics, and queries CloudTrail for attacker activity timeline.
|
|
|
|
## Dependencies
|
|
|
|
| Package | Version | Purpose |
|
|
|---------|---------|---------|
|
|
| requests | >=2.28 | HTTP API calls |
|
|
| AWS CLI | >=2.0 | AWS service interaction (subprocess) |
|
|
|
|
## CLI Usage
|
|
|
|
```bash
|
|
python agent.py --incident-id INC-2025-001 --username compromised-user \
|
|
--access-key-id AKIA... --instance-id i-0abc123 --output report.json
|
|
```
|
|
|
|
## Arguments
|
|
|
|
| Argument | Required | Description |
|
|
|----------|----------|-------------|
|
|
| `--incident-id` | Yes | Incident ticket identifier |
|
|
| `--username` | Yes | Compromised IAM username |
|
|
| `--access-key-id` | No | Access key ID to disable |
|
|
| `--instance-id` | No | EC2 instance ID to isolate |
|
|
| `--forensic-sg` | No | Forensic isolation security group ID |
|
|
| `--output` | No | Output report file path |
|
|
|
|
## Key Functions
|
|
|
|
### `aws_disable_access_key(username, access_key_id)`
|
|
Disables a compromised IAM access key by setting status to Inactive via `aws iam update-access-key`.
|
|
|
|
### `aws_attach_deny_all(username)`
|
|
Attaches the `AWSDenyAll` managed policy to block all API calls from the compromised user.
|
|
|
|
### `aws_isolate_ec2(instance_id, forensic_sg)`
|
|
Changes an EC2 instance's security groups to a forensic isolation group that denies all traffic.
|
|
|
|
### `aws_snapshot_ebs(instance_id)`
|
|
Creates forensic snapshots of all EBS volumes attached to the compromised instance.
|
|
|
|
### `aws_query_cloudtrail(username, hours_back)`
|
|
Queries CloudTrail for all API events made by the compromised identity, parsing source IP, user agent, and resources.
|
|
|
|
### `aws_list_attacker_resources(username, events)`
|
|
Filters CloudTrail events for resource creation actions (Create*, Run*, Put*, Attach*).
|
|
|
|
### `aws_check_all_regions_instances()`
|
|
Scans all AWS regions for running EC2 instances to detect crypto-mining deployments.
|
|
