Frequently Asked Questions #
Which cybersecurity credentials should consulting staff hold? #
Common credentials include CISSP (Certified Information Systems Security Professional, governance focus), CISM (Certified Information Security Manager, management focus), CompTIA Security+ (foundational), and OSCP (Offensive Security Certified Professional, hands-on penetration testing). The right credential depends on the engagement type.
Does NIST CSF 2.0 differ from the prior version? #
NIST Cybersecurity Framework (CSF) 2.0 was published in February 2024 and adds a sixth function called Govern alongside the original Identify, Protect, Detect, Respond, and Recover functions. The update broadened applicability beyond critical infrastructure to all organizations.
What does SOC 2 Type II audit preparation involve? #
SOC 2 Type II evaluates control operating effectiveness over a defined audit period, typically 6 to 12 months, rather than at a single point in time. Preparation work includes scoping the system boundary, control design documentation, evidence collection, gap remediation, and readiness assessment before the formal CPA examination.
How does HIPAA Security Rule compliance get tested? #
The HIPAA Security Rule (45 CFR Part 164, Subpart C) sets administrative, physical, and technical safeguards for electronic protected health information. Compliance testing typically combines a risk analysis, policy and procedure review, technical configuration review, penetration testing, and remediation planning. Penetration testing often follows the PTES (Penetration Testing Execution Standard) methodology.
