Security Analysis and Vulnerability Assessment

Wireshark with custom dissectors decodes telecom-specific protocols including GTP, Diameter, SBI/HTTP2, and NAS for security analysis. Nessus and Qualys provide vulnerability scanning for network function hosts, Kubernetes nodes, and management interfaces. Burp Suite and OWASP ZAP test API security for SBI and NEF exposure interfaces. Nmap and specialized telecom scanning tools probe for open ports and misconfigured interfaces. Security specialists must be proficient with both general-purpose cybersecurity tools and telecom-specific protocol analyzers.
