Security Assessment and Penetration Testing Questions

Covers the full spectrum of assessing and hardening systems and applications. Topics include systematic assessment methodologies such as threat modeling asset inventory scoping vulnerability identification and remediation prioritization; distinctions between vulnerability assessment and penetration testing including when to use each and what each delivers; application security testing approaches targeting common vulnerabilities and exploitation scenarios; hardening guidance for architecture configuration and access controls; severity and risk rating practices using established scoring frameworks and contextual reasoning; use of automated scanning and manual testing techniques; and how to communicate findings and remediation roadmaps to both technical teams and business stakeholders.

Audit an OAuth2-based authentication flow for a microservice that delegates auth to an identity provider. Describe misconfigurations and vulnerabilities to test for (improper token validation, open redirectors, insecure client secrets, incorrect scopes), how to safely verify them, and specific remediation steps for each issue.

During an authenticated penetration test you discover a webshell on a production host. Describe the immediate steps you would take to contain risk, preserve forensic evidence, coordinate with operations and legal, and communicate to stakeholders while minimizing further disruption and risk of data loss.

A web API uses JWTs for authorization. Describe a targeted test plan to identify token-related issues: signature verification failures, algorithm confusion (alg=none, RS/HS misuse), token replay, insufficient audience/issuer validation, insecure storage, and long-lived refresh tokens. For each, state how you'd test and recommended fixes.

You are planning an internal penetration test of a hybrid enterprise: on-prem Active Directory plus cloud-hosted workloads. Describe a methodology to test pivoting and lateral movement safely: initial discovery, exploitation vectors, use of tools (e.g., BloodHound, WinRM/PSExec alternatives), segmentation validation, and precautions to avoid impacting business services.

Create a multi-stage adversary emulation plan mapped to MITRE ATT&CK that demonstrates data exfiltration. Include realistic initial access, persistence, privilege escalation, C2 (command-and-control) technique choices, data staging and exfiltration method, detection hypotheses, and concrete test steps that validate detection and response capabilities.
