National Grid aimed to enhance the protection of its online services against cyber-attacks. They needed to identify security weaknesses across their web applications and network services and mitigate risks related to misuse of these services. The engagement focused on evaluating security risks, ensuring end-to-end protection, maintaining high availability, enabling secure transitions, and strengthening authentication mechanisms.
Our Process
Step 1
Evaluated security risks across business-critical web applications and network services
Step 2
Analysed information available from public resources
Step 3
Conducted vulnerability assessments and black/white box penetration testing using automated tools
Step 4
Executed controlled hacking to validate identified, hidden vulnerabilities and strengthened authentication using MFA
Project Challenges
Business-Critical Systems
Testing live, business-critical applications required controlled execution to identify vulnerabilities without impacting availability.
Comprehensive Risk Coverage
Ensuring complete visibility into configuration weaknesses and potential misuse points across network access layers required multiple testing approaches.
Our Development Journey
We followed a structured security testing approach aligned with OWASP security testing guidelines. Through vulnerability assessment, penetration testing, and controlled exploitation, we helped National Grid gain clear visibility into its security posture and understand risks across its information systems and network services.
Results
Delivered detailed test plans, testing approaches, and black box / white box penetration testing reports
Identified vulnerabilities and configuration weaknesses exploitable through network access points and shared countermeasure recommendations
Completed risk assessments and outlined future plans aligned with emerging technologies
