A practical start to your Threat-Driven Defense journey

You understand and have experienced the challenge of your organisation being solely compliance driven or perhaps you read our previous blog. How do you start on a more effective path? Cybersecurity can feel like a daunting, expensive undertaking, especially for organisations dependent on continuous digital innovation for their success - and who isn’t?. Jargon, complex frameworks, and the ever-present threat of sophisticated attacks can make it seem like an impossible challenge. But effective cybersecurity doesn't have to break the bank. A threat-driven approach, using accessible frameworks like STRIDE, MITRE ATT&CK, and MITRE D3FEND, can actually save you money in the long run. It's about working smarter, not just spending bigger. This blog will outline a simple, actionable path to get you started.

Laser Focus, Not Scattershot Spending, with STRIDE

Many organisations fall into the trap of throwing money at every perceived vulnerability. This "scattershot" approach is not only ineffective but also incredibly wasteful. STRIDE offers a more strategic, focused approach. Instead of trying to protect everything at once, STRIDE encourages you to prioritise. Select one critical system or application – perhaps your customer database, your website, or your point-of-sale system – and analyze it using the STRIDE framework.

STRIDE provides a structured way to think like an attacker:

• Spoofing: Could someone impersonate a legitimate user or system?

• Tampering: Could someone maliciously modify data or code?

• Repudiation: Could someone deny they performed a malicious action?

• Information Disclosure: Could sensitive information be exposed to unauthorized parties?

• Denial of Service: Could the system be rendered unavailable to legitimate users?

• Elevation of Privilege: Could someone gain higher levels of access than they should have?

By focusing on one system and systematically applying STRIDE, you can identify the most critical threats without spending a fortune on broad, generic security solutions. This targeted approach allows you to allocate your limited budget where it matters most.

Free Intelligence: Knowing Your Enemy with MITRE ATT&CK

MITRE ATT&CK is a game-changer, especially for budget-conscious organizations. This freely available knowledge base provides a wealth of information on adversary tactics and techniques. It's like having a team of expert security analysts at your disposal – without the hefty consulting fees!

ATT&CK maps out the various stages of an attack, from initial reconnaissance to the attacker's ultimate objective. By mapping the threats you identified with STRIDE to specific ATT&CK techniques, you gain a deeper understanding of how an attacker might try to exploit your vulnerabilities. This knowledge is invaluable for prioritising your defenses and avoiding costly missteps.

Smart Defense Spending with MITRE D3FEND

MITRE D3FEND complements ATT&CK by providing a catalog of defensive techniques. Crucially, D3FEND focuses on the functions of these defenses, not specific vendor products. This allows you to explore cost-effective options, including open-source tools, built-in features of your existing systems, and less expensive alternatives to enterprise-grade solutions.

For each ATT&CK technique relevant to your organisation, consult D3FEND to identify appropriate defensive measures. Perhaps you can leverage existing logging and monitoring capabilities instead of investing in a new security information and event management (SIEM) system. Or maybe you can strengthen access controls through better password management and multi-factor authentication, rather than purchasing a complex identity management platform. D3FEND empowers you to make informed decisions about your security investments, maximising your ROI.

Gradual Implementation, Long-Term Savings

Don't feel pressured to implement everything at once. Cybersecurity is a marathon, not a sprint. Start by focusing on the most critical threats you identified using STRIDE and ATT&CK. Choose one or two key defensive techniques from D3FEND and implement them gradually. This phased approach makes cybersecurity more manageable for smaller budgets and allows you to learn and adapt along the way.

Real-World Cost Savings:

• Reduced tool sprawl: By focusing on specific threats, you avoid the temptation to buy a multitude of security tools, many of which might be redundant or unnecessary.

• Leveraging existing resources: D3FEND helps you identify and utilise built-in security features and existing capabilities in your current systems, minimising the need for new purchases.

• Prioritised spending: You allocate your budget to address the most critical threats, ensuring that every dollar is spent wisely.

• Preventing costly breaches: A threat-driven approach aims to prevent attacks before they happen, saving you the potentially devastating costs associated with a security incident, including data recovery, legal fees, regulatory fines, and reputational damage.

Example:

You're concerned about "Information Disclosure" (STRIDE) related to your customer data. You map this to the "Data Exfiltration" technique (ATT&CK). D3FEND suggests "Data Loss Prevention" (DLP). Instead of immediately investing in a high-end DLP solution, you might begin by implementing strong encryption for your database and enforcing strict access controls. These measures are often built into database systems and can be implemented with minimal cost.

By embracing this practical, threat-driven approach, you can significantly improve your cybersecurity posture without emptying your wallet. It's about being strategic, focusing on what matters most, and making smart, informed decisions about your security investments. Start small, build gradually, and watch your security – and your budget – grow stronger.
