If you’ve had every tool out of the shed, it’s time to rethink your cyber security approach.
Cyber security is awash with new solutions. To meet the changing threats to networked systems, new and innovative technologies are constantly being developed. It’s tempting to want to keep up to date through new kit. But there are challenges to new deployments. New tools may not integrate smoothly with existing infrastructure, which can lead to rising developer costs and even new vulnerabilities. Vendor lock in risks, plus long term upgrade and support costs can also multiply.
A successful approach starts with understanding and owning the risk. Critical national infrastructure (CNI) organisations can find they have every tool going, but are still uncertain about the effectiveness of their cyber security. It’s not enough to plug in an advanced threat detection solution, or tick an ISO box and assume you’re covered. This is where the Cyro Cyber team come in. We believe in putting people and process before the right technology, and we’re not tied to a particular vendor or technology.
CNI organisations also have specific needs. With complex legacy systems in place, they need neutral advice on how to make their networks resilient for the long term. At Cyro Cyber, we focus spend on services first, rather than a new tool from an already full shed. We can run security assessments to see where the organisation’s vulnerabilities are and then develop processes to manage the cyber risk environment.
For CNI organisations, we recommend:
Start Where You Are: map what you have and understand the extent of your system. See what you need by scrutinising controls and looking at what’s already monitored and isolated. Then don’t buy anything new until the current procedures and controls actually work in practice.
Involve the Team: devise a security management plan and bring together a working group. Perhaps appoint some independent advisors, as well as cyber security experts. Create a schedule for reporting.
Create Evidence: start a testing programme for the systems you already have. Develop a schedule for cyber incident exercises and monitor the results. Also use your existing compliance networks to accelerate the Cyber Assessment Framework (CAF).
This approach will go some way to meeting the requirements of the Cyber Security & Resilience Act. The previous self-assessment, hands-off approach has allowed organisations to overstate their resilience. They haven’t had to test every tool and prove it works in practice, merely to show they have it. At the level of CNI organisations, this is a direct risk to national security, business continuity, and shareholder confidence.
Stop buying new tools and rethink your approach to cyber security. Cyro Cyber’s experience helps organisations to plot change from providing assurance to showing clear evidence. We can help you do the hard yards of policy implementation and then select the right technology tools for the organisation’s specific needs. Get in touch today.
