AWS Security Hub is a cloud security posture management (CSPM) service. It performs automated, continuous security best practice checks against AWS resources, helping to identify misconfigurations and aggregating security alerts (i.e. findings) in a standardized format. This process allows security findings to be easily enriched, investigated, and remediated.

Security Hub Core Components

The core components of AWS Security Hub include:

• Findings: Potential security issues generated by AWS services and partner solutions integrated with Security Hub.

• Insights: Collections of related findings provide visibility into specific security issues and assist in threat hunting and incident investigations.

• Security Standards: Sets of automated compliance checks based on industry best practices and recognised standards, such as the CIS AWS Foundations Benchmark.

AWS Security Hub Features

Security and Compliance Checks:

• Automated, continuous security best practice checks: Uses an event-based or scheduled continuous monitoring system with a highly-curated set of security best practices vetted by AWS security experts.

• Compliance (Industry and regulatory frameworks): Security Hub offers standards aligned to industry and regulatory frameworks such as PCI DSS, CIS AWS Foundations Benchmark, and NIST.

Managing Security Alerts:

• Continuous cross-region aggregation of findings for a centralized view across accounts and linked Regions.

• Simplified integrations with ticketing, chat, incident management, logging, and auto-remediation tools.

Automation and Response:

• Automated updates of findings using Security Hub Automation Rules.

• Integration with Amazon EventBridge to create custom automated workflows for automated response, remediation, and enrichment actions.

Cost Optimisation:

• 30-day free trial for every enabled AWS account in each Region with a complete feature set and security best practice checks included.

• Pricing based on the quantity of security checks, ingested findings, and rule evaluations processed per month.

AWS Security Hub Use-Cases:

• Cloud Security Posture Management (CSPM): Reduce risk through automated checks based on curated security controls. Simplify compliance management with built-in mapping capabilities for frameworks like CIS, PCI DSS, and more.

• Security Orchestration, Automation, and Response (SOAR): Automatically enrich, remediate, or send findings to ticketing systems using Security Hub's integration with EventBridge.

• Security Cost Optimisation and Efficiency: Streamline data ingestion and normalize findings, simplifying the overall process.

Integrated Services

AWS Security Hub can be integrated with numerous AWS services, including Amazon GuardDuty, Amazon Inspector, Amazon Macie, AWS Firewall Manager, AWS IAM Access Analyzer. Each of these services sends its findings to Security Hub where they are consolidated for easier management and analysis

Architectural Design Pattern

AWS Security Hub leverages an event-driven architectural pattern. It subscribes to finding-related events from its integrated services, and whenever a new finding is generated, it's sent to Security Hub. This can trigger predefined AWS Lambda functions to automate responses to the identified security threat or vulnerability.

AWS Security Hub Best Practices

Security Posture Management

• Enable Security Hub across all accounts to get a unified view of your security and compliance state.

• Regularly review insights and findings to understand the common security issues within your environment and take appropriate actions.

Security Incident Response

• Configure automated response and remediation using AWS Lambda functions to respond quickly to security incidents.

• Forward Security Hub findings to chat operations or incident response platforms for timely notifications to the concerned teams.

Integration and Management

• Enable AWS Config for all the resources that you want Security Hub to check for compliance.

• Use Security Hub APIs to automate the management tasks such as importing findings from other AWS services and enabling or disabling security standards.

Threat Intelligence and Detection

• Integrate AWS Security Hub with threat intelligence services to leverage external threat intelligence feeds for better detection.

• Use machine learning capabilities of integrated services such as Amazon GuardDuty and Amazon Macie for anomaly detection and proactive threat management.

Compliance Management

• Enable the compliance standards that apply to your environment. Customise your own checks if the built-in checks don't cover all your requirements.

Data Protection

• Use AWS Key Management Service (KMS) to encrypt all the sensitive data in Security Hub findings for an additional layer of security.

Cost and Performance

• Monitor costs related to Security Hub usage with AWS Cost Explorer to make sure you're staying within your budget.

• Use AWS Compute Optimizer to ensure you're using the optimal resources for your security workloads.

AWS Security Hub Anti-patterns

• Ignoring Findings: Security findings should be treated with priority, as they indicate potential vulnerabilities or threats.

• Overlooking Compliance Checks: Continuously monitor and address compliance check failures to maintain the compliance posture.

• Limiting Integrations: Security Hub should be integrated with all relevant AWS services and partner solutions for a comprehensive and efficient security and compliance management.

Recommendations for Startups, SMBs & Modern Businesses

• Start-ups: AWS Security Hub's automated security checks and compliance status monitoring save valuable time and help avoid expensive non-compliance penalties.

• SMEs: Security Hub's integrations with other AWS services and APN solutions can enhance their security strategy's efficiency and coverage.

• Modern Enterprises: Security Hub's ability to centralise security findings from multiple accounts can streamline security and compliance processes.

In conclusion, AWS Security Hub is an integral part of any organisation's AWS environment. By following best practices and avoiding anti-patterns, organisations can maximise the benefits of Security Hub, thereby enhancing their overall security posture.
