Information Security Compliance

The customer is a utility company required an independent assessment of its current Process Control Domain (OT) security standard and procedures including the current security operating model against relevant standards including but not limited to:

  • ISACA
  • IIA
  • COBIT
  • ISO 27001
  • IEC 62443
  • NIST
  • NERC-CIP
  • SANS Top 20 critical controls
  • ISA
  • ANSI

The primary objective of the project was to perform an independent risk based audit to assess OT security governance, security processes and procedures, security configuration controls implementation in the systems being used and the physical area of where these controls are implemented and propose an improvement. A strategy comprising a design of a new or improved controls that comply with ISA 62334, relevant standards and ensure robust and resilient operation.

The result of this audit discovered weaknesses/gaps with respect to security best practices and standards in OT security governance including policies and procedures; weaknesses in security configuration controls in operating systems, network devices, and the system that are being used; business continuity management; and physical security of the control areas. The audit team followed the ISACA’s IS Audit and Assurance Standards; Professional Practices Framework for IS Audit/Assurance.

EGCD team also proposed a strategy for:

  • Organization Governance.
  • OT network architecture design.
  • Legacy System.
  • Knowledge management.
  • Training and knowledge transfer.

In addition to the audit and recommendation, we also ensured that all processes, procedures and tools which were created during the audit repeatable utilized and knowledge was transferred to relevant teams. A wider and systematic knowledge transfer process was created for all staff.

Information Security Risk Management

Working within an Oil & Gas company, EGCD Consultants developed a cyber security framework aligned with, and prioritized, according to client business needs. A simple risk assessment that looked at the operational environment was conducted in order to determine the likelihood of a cyber-security event and the impact that the event could have on the organization. Detailed risk assessments on individual facilities however follwed once the framework has been developed. This step enabled the project to build the business case for the framework and act as a reference point when prioritizing security controls, implementation, milestones and enable the business to answer ‘why are we doing this, what risk is it mitigating?” when new measures are challenged.

EGCD consultant formed a team to conducted a detailed risk assessment addressing physical and cyber security threats, internal and external threats and consider hardware, software, and information as sources for vulnerabilities. Considering all aspects of the client’s assets, including unintended changes in system configuration brought about by maintenance, temporary supplier connections to the system for support and even subtle changes in supplier design that could introduce new vulnerabilities through spare parts or upgrades, which should be considered and/or tested in the same manner as the original system components. We applied the methodologies documented in IEC 62443 series taking into consideration the client specific framework: Essentially the objective was to provide a repeatable process capable of determining and implementing the appropriate security requirements.
