5 automated security scanners

Identity-Centric Security

Purpose: The Identity-Centric Security Scanner is designed to identify vulnerabilities and security weaknesses in identity providers and authentication mechanisms by probing DNS records, HTTP headers, TLS configurations, and network ports. Its primary purpose is to ensure the robustness of an organization’s identity infrastructure against potential threats.

What It Detects:

Insecure DNS Records: The scanner checks for misconfigurations or missing security-related DNS records such as TXT, MX, NS, CAA, and DMARC records.
Weak Security Headers: It ensures that critical security headers are present and properly configured in HTTP responses.
Vulnerable TLS Configurations: The scanner identifies outdated protocols, weak cipher suites, and other TLS-related vulnerabilities such as TLSv1.0, TLSv1.1, RC4, DES, and MD5.
Open Ports and Services: It scans for open ports and identifies services that may be exposed to unauthorized access, commonly scanning ports like 21, 22, 23, 80, 443, and 3306.
API Security: The scanner analyzes API endpoints for security vulnerabilities such as improper authentication or data leakage by checking for missing authentication headers in API responses.

Inputs Required:

domain (string): Primary domain to analyze (e.g., acme.com). This is the main identifier used to check DNS records, HTTP headers, and TLS configurations.
ip_range (string): IP range to scan for open ports and services (e.g., 192.168.1.0/24). This helps in identifying potential network vulnerabilities by scanning the specified IP addresses for open ports.

Business Impact: Ensuring robust identity infrastructure is crucial as it directly impacts the security of sensitive user data, authentication mechanisms, and overall system integrity. Poorly configured DNS records, weak security headers, vulnerable TLS configurations, exposed services, and insecure APIs can lead to unauthorized access, data leakage, and other severe consequences that may compromise an organization’s security posture.
