Performing Cloud Forensics Investigation

Performing Cloud Forensics Investigation

Overview

Cybersecurity skill for performing cloud forensics investigation. Follows industry best practices and security standards.

When to Use

Trigger phrases:

• "performing cloud forensics investigation"

• "Conduct forensic investigations in cloud environments by collecting and analyzin"

• When investigating a security breach in AWS, Azure, or GCP cloud environments

• For collecting volatile and non-volatile evidence from cloud infrastructure

• When tracing unauthorized access through cloud service API logs

• During incident response requiring preservation of cloud-based evidence

• For analyzing compromised virtual machines, containers, or serverless functions

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

• Administrative access to the cloud account under investigation
• AWS CLI, Azure CLI, or gcloud CLI configured with appropriate permissions
• Understanding of cloud-native logging (CloudTrail, Activity Log, Audit Log)
• Forensic workstation with cloud SDKs installed
• Knowledge of IAM, networking, and compute services in target cloud
• Evidence preservation procedures for cloud environments

Workflow

# 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. Plan Operations — Define objectives, scope, and success criteria for cloud forensics investigation operations.
2. Prepare Environment — Set up tools, access, and data sources required for cloud forensics investigation.
3. Execute Core Workflow — Perform the cloud forensics investigation operations following established procedures.
4. Validate Results — Verify that results meet quality standards and objectives.
5. Report Findings — Document results, observations, and recommendations.
6. Follow Up — Track remediation actions and verify fixes where applicable.

Tools

• Analysis Platform — Data processing and visualization
• Collaboration Tools — Team coordination and knowledge sharing

Process

1. Reconnaissance — Gather target information, identify attack surface, enumerate services
2. Analysis/Exploitation — Execute the technique, analyze results, document findings
3. Reporting — Document IOCs, write findings, provide remediation recommendations

Verification

• All cloud forensics investigation 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
