Penetration Testing for Critical Infrastructure: Ensuring Resilience
Infrastructure penetration testing simulates a cyber attack on the IT structure of an organisation to identify key vulnerabilities and areas of weakness within its security systems. It’s an extremely important method for ensuring organisations can be proactive when it comes to the security of critical infrastructure, leading to the prevention of catastrophic failures and the development of robust reaction plans if and when they’re needed.
By simulating real-world attack scenarios, infrastructure penetration testing assists in identifying and addressing potential points of exploitation, ensuring a resilient defence against evolving cyber threats and safeguarding sensitive corporate assets.
Why Critical Infrastructure Penetration Testing is Essential
Critical infrastructure is faced with a set of unique vulnerabilities from a cybersecurity standpoint, namely due to its highly interconnected nature and its reliance on digital systems. Operational technology (OT) and information technology (IT) intersect, exposing vulnerabilities while ageing systems with no resources to be improved often can’t keep up with the evolving nature of modern cyber-attacks.
Preventing Catastrophic Failures
Critical infrastructure penetration testing can proactively identify and address vulnerabilities within these interconnected systems of critical infrastructure. Simulating cyber attacks uncovers weaknesses that can then be addressed, safeguarding against potential service disruptions or safety incidents. This is of vital importance to sectors such as healthcare and energy to ensure system integrity
Safeguarding Sensitive Data
This form of testing also helps protect highly confidential and sensitive information by exposing potential areas where a data leak might occur. Systems can then be updated proactively to prevent any data breach. If any time-sensitive information is involved, such as health information, everything must be done to protect it to maintain a high level of public trust and to meet the strict regulatory standards that are in place around that kind of data.
Ensuring Compliance and Avoiding Penalties
By carrying out our critical infrastructure penetration testing, you can ensure that all cybersecurity requirements are being met, particularly from a regulatory standpoint. This will ensure your organisation avoids any fines or penalties associated with being non-compliant, while also avoiding the reputational damage associated with not meeting industry standards. DigitalXRAID specialises in ensuring our clients not only meet these requirements but exceed them, providing the ultimate peace of mind for stakeholders and customers alike.
Building Resilience Against Evolving Threats
Regular penetration testing allows critical infrastructure to keep up to date with the evolving nature of modern cyber-attacks. Testing should be systematic and regularly scheduled, with the latest techniques employed to ensure security is as up-to-date as possible.
Understanding the Process of Infrastructure Pen Testing
Penetration testing for critical infrastructure is a systematic process, designed to identify and address any vulnerabilities present within an organisation’s cybersecurity system. It follows a step-by-step approach, ensuring easy replication and a thorough result. These steps are:
Reconnaissance
Gathering information about the critical infrastructure, identifying potential targets, and understanding the overall landscape.
Target Enumeration
Listing and identifying specific targets within the critical infrastructure for penetration testing.
Vulnerability mapping
Identifying and mapping vulnerabilities in the targeted infrastructure components to assess potential points of exploitation.
Target exploitation
Actively exploiting identified vulnerabilities to assess the security resilience of critical infrastructure systems.
Privilege escalation
Elevating access privileges within the critical infrastructure to simulate potential unauthorised access by attackers.
Maintain Access and Lateral Movement
Ensuring continued access to the infrastructure and simulating lateral movement to assess the potential extent of a cyber-attack.
Clean up
Restoring systems and removing traces to leave the critical infrastructure in its original state after the penetration testing process is complete.
Initial Planning and Scoping
The initial planning and scoping stages set the objectives for the testing to ensure it’s aligned with the security goals of the organisation. Key assets, systems, and networks will be identified to ensure pointed testing where necessary. This section is key to setting appropriate boundaries for the test to ensure operational integrity remains intact, while still being able to achieve a comprehensive test.
Threat Modelling and Vulnerability Identification
A combination of automatic tools and expert analysis from the test team will be used to identify vulnerabilities across the entire scoped environment. This will include both common and sector-specific vulnerabilities, resulting in a prioritised list of areas of concern and potential high-risk vulnerabilities. These can then be assessed and remediated proactively to maintain system integrity.
Exploitation and Assessment
The penetration test will go as far as exploiting these vulnerabilities in a safe and controlled manner to determine the impact of a successful attack. This is invaluable in gaining insight into how a potential attacker would go about breaching individual systems to disrupt vital services. This gives the security team real-world information on the impact of such an attack, enabling a response plan to be developed.
Reporting and Remediation Guidance
Once completed, all of this will result in a report being generated detailing any identified vulnerabilities, the impact of these potential vulnerabilities being exploited, and a prioritised list of what to remediate and how. Actionable insights will be generated into how to reduce and minimise risk, while also strengthening the overall system outside of the main vulnerabilities. This allows for a level of informed and guided decision-making around appropriate cybersecurity, leading to improved security outcomes and better overall resilience.
Compliance and Regulations Surrounding Critical Infrastructure
Critical infrastructure and the sectors involved in it are typically some of the most highly regulated in the world. These industry-specific regulations must be both understood and followed — both nationally and internationally. At DigitalXRAID, we ensure all of our teams remain up to date with all key standards such as GDPR and the NIS directive so that you don’t have to.
Penetration testing is often a key requirement when it comes to meeting cybersecurity compliance. We offer bespoke penetration testing services, tailormade to your specific business. This allows your organisation to appropriately mitigate risk cost-effectively and efficiently, limiting any potential for costly fines or severe reputational damage.
