Open System Sciences has been at the forefront of Cybersecurity operations from the onset of the Information Technology age. The term Cybersecurity is typically used to address the technologies and processes used to protect networks, personal computers, servers, and data from attack, damage or unauthorized access. Cybersecurity encompasses the processes, procedures, tactics and techniques necessary to thwart the ongoing and ever-evolving attacks from both insider and external threats. In reality, Cybersecurity is a subset of Information Assurance. The ongoing danger posed to agency and corporate information technology and business systems has been well-documented and is ever-present in the national media. Our highly trained and experienced engineers are engaged in fighting these threats on a daily basis, and “no” network managed by OSS has ever been shut down due to the impact of a cyber attack.

Policy & Governance

Every successful Information Assurance (IA) program consists of processes and procedures which are rooted in clear and impactful policies that are measured through comprehensive governance. OSS has successfully provided both services to numerous Federal government agencies for over 15 years. We have worked directly with agency Chief Information Security Officers (CISOs) to develop overarching governance plans that exceed the requirements of the Federal Information Security Management Act (FISMA) by integrating measurable security practices into everyday IT processes. Our efforts have resulted in substantially reducing the burden of FISMA requirements on system owners and CISOs by leveraging existing IT methodologies such as the Systems Development Life Cycle (SDLC) and Change Management processes as delivery mechanisms for Information Assurance Governance. OSS employs only seasoned IA Subject Matter Experts (SMEs) and Technical Writers to work with government officials in the development of policies that are written in plain language and capture the all critical aspects of the client’s Security Program.

Governance and Policy services offered by OSS include:

  • Risk Management Framework
  • Information Assurance Policy Development
  • Privacy Policy Development
  • Security Assessment and Authorization
  • National Institute of Standards of Technology (NIST) directives
  • Audit Preparation and Response
