Additionally, you will assist in the Federal Information Processing Standard (FIPS) categorization of applications and systems, participate in risk assessments, and perform vulnerability scans and penetration testing to identify security weaknesses. You will document and implement security controls using NIST standards, generate necessary system documentation such as Security Assessment Reports (SARs) and Privacy Impact Analyses (PIAs), and create and maintain project content in the Governance, Risk, and Compliance (GRC) tool. Your expertise will also be required in assessing systems for risks, providing guidance on security requirements for cloud-hosted systems, and staying updated on industry standards and vulnerabilities. This position demands strong problem-solving skills, technical proficiency, and the ability to work collaboratively in a team environment.
