4423 ISSO4423 | TS/SCI
Job Description:OVERVIEW:The ISSO conducts security and risk assessments as required using a range of security accreditation frameworks (e.g., NIST, RMF, Common Criteria, DoD, the Intelligence Community Directives (ICDs)), and works to mitigate risks by applying security controls effectively to achieve an acceptable degree of operational risk. As part of this process, the ISSO performs testing and security assessments to sustain required accreditations. The ISSO promotes the use of secure hardware and software within the systems affected by government and corporate approval standards. The ISSO works to ensure all required security policies and practices are effectively applied to systems and ensures security controls implementing these policies are applied and achieve the proper levels of confidentiality, integrity, availability, and privacy protection throughout the system life cycle.
The ISSO also assists with the execution, analysis, and remediation activities for the vulnerability management program (scanning, assessment, reporting, and mitigation verification) that spans different accreditation entities, three distinct classification domain enclaves (U), (S) and (TS), using the Nessus and Tenable-ACAS vulnerability scanning tools.
