Ensuring Robustness Through Security and Testing Strengthening the Power Sector’s Cyber Defenses

In this edition of Cybersecurity 101, we explore Article 13 of the Central Electricity Authority (CEA) guidelines, which focuses on the security and testing of cyber assets. As the backbone of power sector operations, cyber assets require stringent security measures and rigorous testing to mitigate vulnerabilities and ensure reliable functioning. This article provides an overview of the key provisions of Article 13 and a detailed analysis of its implementation challenges, objectives, and recommendations.

Section 1: Verbatim Clauses of Article 13 - Security and Testing of Cyber Assets

a) The Responsible Entity shall ensure the security of all in-service phase as well as standby Cyber Assets through regular firmware/software updates and patching, vulnerability management, penetration testing (of combined installations), securing configurations, and supplementing security controls. The CISO shall maintain details of update versions of each firmware and software and their certification if received from OEMs.

b) The Responsible Entity shall regularly carry out vulnerability assessments of all Cyber Assets owned or under their control. If a Cyber Asset is found vulnerable to exploits or upon any patch updates or major configuration changes, further Penetration Testing may be carried out offline or in a suitably configured laboratory test-bed to identify additional vulnerabilities.

c) The Responsible Entity shall specify security requirements and evaluation criteria during each phase of their procurement process.

d) The Responsible Entity shall ensure that all Cyber Assets being procured conform to the type tests as mentioned in the specification for type testing listed in the bid document. Type test reports of tests conducted in NABL-accredited Labs or internationally accredited labs (within the last 5 years from the date of bid opening) shall be mandated to be submitted along with the bid. In case the submitted Type Test reports are not as per specification, re-tests shall be conducted without cost implications to the Responsible Entity.

e) The Responsible Entity shall ensure that all communicable devices are tested for communication protocols as per the ISO/IEC/IS standards listed in MoP Order No. 12/13/2020-T&R dated 8th June, 2021 (Annexure-B).

f) The Responsible Entity shall ensure that all Critical Systems designed with Open Source Software are adequately cyber secured.

g) The Responsible Entity, as a best practice upon any cyber security breach incident, shall carry out cyber security tests at any lab designated for cyber testing by the Ministry of Power. These tests shall be similar to Pre-Commissioning Security Tests and those essential for Post-Incident Forensics Analysis.

Section 2: Analysis of Article 13 - Objectives, Challenges, and Suggestions

Clause (a): Regular Updates and Patching

Objective: Maintain robust defense mechanisms by ensuring all cyber assets are up to date with the latest security patches.

Challenges: Inconsistent patching schedules, lack of OEM support for older systems, and manual update tracking.

Suggestions: Implement automated patch management tools and maintain a centralized database for tracking firmware/software versions and certifications.

Clause (b): Vulnerability Assessment and Penetration Testing

Objective: Proactively identify and address vulnerabilities before they are exploited.

Challenges: Limited access to test-bed facilities and skilled professionals for penetration testing.

Suggestions: Partner with certified cybersecurity labs for periodic testing and invest in upskilling internal teams on advanced vulnerability assessment techniques.

Clause (c): Security Requirements in Procurement

Objective: Ensure cybersecurity is integrated into the procurement process to prevent entry of compromised assets.

Challenges: Poorly defined security specifications and lack of vendor accountability.

Suggestions: Standardize procurement guidelines with detailed cybersecurity evaluation criteria and include penalties for non-compliance.

Clause (d): Conformance to Type Testing Standards

Objective: Validate the reliability and safety of procured assets through rigorous testing.

Challenges: Dependence on external testing agencies and delays in receiving type test reports.

Suggestions: Maintain a pre-approved list of accredited labs and collaborate with vendors to expedite the testing process.

Clause (e): Protocol Testing of Communicable Devices

Objective: Ensure secure and interoperable communication across devices in compliance with established standards.

Challenges: Complexities in multi-vendor environments and outdated protocol implementations.

Suggestions: Mandate interoperability tests during procurement and conduct periodic audits to verify compliance.

Clause (f): Securing Open Source Software

Objective: Protect critical systems utilizing open-source solutions from known and emerging vulnerabilities.

Challenges: Rapid evolution of open-source ecosystems and lack of specialized expertise.

Suggestions: Regularly update open-source components, use trusted repositories, and engage with the open-source community to adopt best practices.

Clause (g): Post-Breach Testing and Forensics

Objective: Strengthen security postures through in-depth analysis of breaches and vulnerabilities.

Challenges: Limited availability of advanced testing facilities and forensic expertise.

Suggestions: Establish dedicated forensic labs within the organization or region and provide training for handling breach incidents effectively.

Conclusion

Ensuring the security and testing of cyber assets is a cornerstone of a resilient power sector. Article 13 of the CEA guidelines provides a comprehensive framework to protect these critical assets, emphasizing proactive measures and post-incident analysis. By addressing the challenges outlined above and adopting the suggested improvements, the power sector can significantly enhance its cybersecurity posture and operational reliability.
