TLS and Certificate Compliance Monitoring

PCI-DSS Requirement 4 compliant cryptography and certificate management

// 01 — Overview

Project Description

This project encompasses auditing the HTTPS infrastructure used in the organization's web services for compliance with encryption standards, TLS versions and security headers.

PCI-DSS Requirement 4 mandates that cardholder data must be protected with strong cryptography during transmission. Weak protocols must be disabled, certificate expiration dates must be tracked, and secure cipher suites must be used.

The solution is implemented with TLS version control, certificate validity tracking and regular monitoring of security header policies.

// 02 — Methodology

Project Methodology

Comprehensive TLS and certificate compliance audit

1

TLS Configuration Analysis

All web services are scanned. It is checked that TLS 1.2 and higher versions are used and weak cipher suites are disabled.

2

Certificate Inventory and Validity Tracking

SSL/TLS certificate inventory is created. Certificate expiration, CA reliability, key strength and revocation status are checked.

3

Security Header Audit

Security headers such as HSTS, CSP, X-Frame-Options are checked. Compliance with best practice configurations is evaluated.

4

Vulnerability Detection and Reporting

Known TLS vulnerabilities such as Heartbleed, POODLE, BEAST are checked. Risky configurations are reported.

5

Continuous Monitoring and Alerting

Certificate expiration dates are continuously monitored. Automatic checks are performed for new TLS vulnerabilities.

// 03 — Benefits
