BeyGoo Attack Surface Management (ASM) is a module that provides continuous visibility into an organization's external digital assets. It maps, analyzes, and monitors the entire external infrastructure in real time, covering domains, subdomains, public IP addresses, SSL/TLS certificates, APIs, and online services. Key functional areas include: - Continuous asset monitoring: identifies exposed domains, subdomains, IPs, open ports, and technologies in use. - Advanced fingerprinting: detects software versions, frameworks, and services running on digital assets. - Vulnerability detection: correlates findings against CVE and NVD databases to identify risks in exposed services. - SSL/TLS certificate analysis: flags expired, self-signed, or misconfigured certificates. - Phishing and cloned site detection: monitors lookalike domains using favicon, HTML structure, and SSL certificate similarity. - DNS monitoring: detects DNS hijacking and unauthorized changes to A, MX, and TXT records. - Exposed API detection: identifies public endpoints and potential data leaks from misconfigured APIs. - HTTP header analysis: reviews security headers for misconfigurations and vulnerabilities. - Change history tracking: records variations in the attack surface over time to detect suspicious patterns. - Certificate and domain expiration monitoring: tracks SSL and domain renewal status. - Authentication portal detection: identifies exposed login pages, databases, and other critical services. The module supports use cases including shadow IT discovery, cloud asset monitoring, third-party risk assessment, and support for Red/Blue Team exercises.
