AWS Security Hub provides:

1. Centralized Security Management: Single pane of glass for security findings

2. Automated Security Checks: Continuous monitoring and assessment

3. Compliance Monitoring: Track compliance with security standards

4. Integration: Works with AWS security services and third-party tools

5. Automated Response: Trigger actions based on security findings

Enable Security Hub using AWS SDK:

``typescript

// Security Hub service

import {

SecurityHubClient,

EnableSecurityHubCommand,

EnableStandardsCommand,

GetEnabledStandardsCommand,

BatchEnableStandardsCommand,

StandardsSubscriptionRequest

} from '@aws-sdk/client-securityhub';

interface SecurityHubConfig {

region: string;

standards: string[];

}

class SecurityHubService {

private client: SecurityHubClient;

constructor(config: SecurityHubConfig) {

this.client = new SecurityHubClient({ region: config.region });

}

async enableSecurityHub(): Promise {

try {

const command = new EnableSecurityHubCommand({

EnableDefaultStandards: true,

Tags: {

Environment: 'Production',

Service: 'SecurityHub'

}

});

await this.client.send(command);

console.log('Security Hub enabled successfully');

} catch (error) {

console.error('Error enabling Security Hub:', error);

throw error;

}

async enableSecurityStandards(standards: StandardsSubscriptionRequest[]): Promise {

try {

const command = new BatchEnableStandardsCommand({

StandardsSubscriptionRequests: standards

});

await this.client.send(command);

console.log('Security standards enabled successfully');

} catch (error) {

console.error('Error enabling security standards:', error);

throw error;

}

async getEnabledStandards(): Promise {

try {

const command = new GetEnabledStandardsCommand({});

const response = await this.client.send(command);

console.log('Enabled standards:', response.StandardsSubscriptions);

} catch (error) {

console.error('Error getting enabled standards:', error);

throw error;

}

// Usage example

async function main() {

const securityHub = new SecurityHubService({

region: 'us-west-2',

standards: [

'arn:aws:securityhub:::ruleset/cis-aws-foundations-benchmark/v/1.2.0',

'arn:aws:securityhub:us-west-2::standards/aws-foundational-security-best-practices/v/1.0.0'

]

});

// Enable Security Hub

await securityHub.enableSecurityHub();

// Enable security standards

const standards: StandardsSubscriptionRequest[] = [

{

StandardsArn: 'arn:aws:securityhub:::ruleset/cis-aws-foundations-benchmark/v/1.2.0',

EnabledRegions: ['us-west-2']

},

{

StandardsArn: 'arn:aws:securityhub:us-west-2::standards/aws-foundational-security-best-practices/v/1.0.0',

EnabledRegions: ['us-west-2']

}

];

await securityHub.enableSecurityStandards(standards);

// Get enabled standards

await securityHub.getEnabledStandards();

}
