In prioritizing cyber risks, it's crucial to start with a comprehensive risk assessment, identifying various threats such as malware, phishing, or insider threats. Each risk should be evaluated based on potential impact and likelihood of occurrence, considering data sensitivity, regulatory requirements, and the overall business context. This process helps create a prioritized list of risks, focusing efforts on those posing the most significant harm or being most likely to occur. Next, asset valuation is essential, understanding the value of assets like hardware, software, data, and even company reputation

Create a comprehensive inventory of all assets, including hardware, software, data, and critical systems. Include both physical and digital assets. Determine the value of each asset to the organization, considering factors like business impact, data sensitivity, and regulatory requirements. Assess the potential impact of each identified threat on your business operations, financials, reputation, and legal standing. Assign impact ratings (e.g., high, medium, low) based on the severity of the potential consequences. Combine the impact and likelihood assessments to calculate a risk rating for each threat scenario. This can be done using a risk matrix, where risks are plotted based on their impact and likelihood

Cybersecurity is a constant battle against evolving threats, like a game of whack-a-mole. You can't address everything at once, so prioritizing risks is essential. By considering the likelihood of occurrence, potential impact, vulnerability level,and ease of mitigation, you can create a risk matrix to guide your mitigation efforts and ensure your most critical assets are protected first. This is an ongoing process, requiring regular reviews and adaptation to stay ahead of the curve in the ever-changing cybersecurity landscape.

Prioritize cyber risks by assessing their potential impact on critical assets, likelihood of occurrence, and regulatory requirements. Focus mitigation of high-impact risks with a high likelihood of occurrence, addressing vulnerabilities that pose the greatest threat to business operations and data integrity. Regular risk assessments and threat intelligence updates can help us ensure proactive and effective prioritization of cybersecurity efforts.

Visibility is key. Most companies suffer from an up-to-date CMDB, whether they're using ServiceNow or a spreadsheet. You can't manage and risk assess what you can't see. Usually there is no single source of truth. Active Directory reports different count of assets from SCCM and other sources like endpoint protection or vulnerability scanning. If the device/server/VM onboarding process does not include installing the necessary agents and conversely removing them when decommissioning assets, then it becomes impossible to risk assess and prioritize mitigation efforts.

You can't protect what you don't know you have. Therefore, the first step to prioritizing a company's assets is to take detailed inventory of them. This may even prevent one from overlooking a long-forgotten server or component that could potentially put the company at risk if it's discovered. Defenses are only as strong as the weakest link. As with every other step in risk mitigation, asset prioritization is an ongoing process. Things are always changing in an organization, and we should always be proactive. Not only should we consider the criticality and sensitivity of assets, but also other aspects such as regulatory requirements and interdependencies. A small "insignificant" server could be a steppingstone into a more critical system.

You need to define the scope and go ahead and open up a spreadsheet because it's cheap and effective. Now list out everything computing you have in the business that the business has paid for: Laptops, phones, printers, routers, firewalls, etc. Once you have your list, the most of the hard part is over, mostly....

List hardware, software, data, and your company's reputation. Identify assets critical for daily operations or those holding sensitive data. You can focus protection on high-value assets to protect your organization effectively. Understand your assets to protect what matters most.

Based on my extensive background, I've seen that thorough asset valuation is a game-changer. Categorize assets not just by their immediate business value but also by their potential long-term impact on your organization's goals. Engage stakeholders from different departments to provide input on asset criticality. Don't overlook the intangible assets like intellectual property and customer trust. Periodically reassess asset values as your business and the threat landscape evolve. This continuous reassessment ensures that your protection efforts remain aligned with the current value and relevance of each asset.

RSS can still be very useful but so can keeping some bookmarks for some of the relevant intelligence sites. Most all of the major vulnerability scanning vendors offer an intelligence feed, but I will always be partial to security wizardry; if you know, you know.

Drawing from over decades of cybersecurity practice, I can attest to the power of robust threat intelligence. Establish a dedicated team to monitor threat intelligence feeds and share relevant information across your organization. Invest in threat intelligence platforms that offer actionable insights specific to your industry. Foster partnerships with external agencies and industry groups to stay ahead of emerging threats. By integrating threat intelligence into your risk management framework, you enhance your ability to anticipate attacks and prioritize your defenses effectively.

Collect and analyze data on emerging and existing threats. Learn the tactics, techniques, and procedures of potential attackers. You can anticipate threats based on trends to enhance your cybersecurity strategy. Stay ahead by being proactive, not just reactive.

Vulnerabilities will choke your business like no other if not done properly. First, remember that not all vulnerabilities are applicable in all architectures. Most sever items require a specific catch, like local access or exposure to a public internet segment. Make sure you resolve with priority, but set your priory to patch based on a relevant risk to your specific architecture, not just taking the vulnerability at face value. Risk re-ranking is a method that can help you better prioritize patching to something that makes strategic sense.

Why vulnerability management is crucial for your security: Identify and classify security weaknesses in your systems. You can regularly scan your systems to detect vulnerabilities. Prioritize vulnerabilities by severity, exploitability, and asset value. Remediate high-priority vulnerabilities first to minimize risk. Tackle vulnerabilities systematically to safeguard your organization.

From my extensive experience, proactive vulnerability management is non-negotiable. Implement a risk-based approach where vulnerabilities are triaged not just by their severity but also by the context of your environment. Automate as much of the vulnerability scanning and patching processes as possible to reduce human error and increase efficiency. Collaborate with software vendors to ensure timely updates and patches. Regularly conduct penetration testing to uncover hidden vulnerabilities. A well-managed vulnerability program is a cornerstone of a resilient cybersecurity posture, minimizing your attack surface.

Do not conduct your BIAs or IAs in a vacuum. Make sure you include relevant business personnel from other parts of the business. For the first one, you should all get in a room and draw on a dry erase board if you have one to get a sense of risk to assets and business. Once you have an idea, you can begin to conduct your impact analysis.

Evaluate the consequences if a system is compromised in business operations, financial loss, or reputation. Highlight risks based on their potential impact on your organization. Focus on preventing the most damaging outcomes to ensure business continuity.

In my career, I've found that detailed impact analysis is essential for effective risk prioritization. Use scenario planning to visualize the effects of different types of breaches on your operations. Engage business leaders to understand the potential financial, operational, and reputational impacts of cyber incidents. Develop impact metrics that are aligned with your business objectives. This approach ensures that your cybersecurity investments are targeted where they can prevent the most significant disruptions, thereby safeguarding your organization's continuity and integrity.

You may find lots of things you need to resolve but as you know money and people are going to be a factor. This will be different for every organization. First, just make sure you are making meaningful mitigations like trying to achieve multiple defense and compliance gains from one change, e.g. a new next generation firewall. Put your money and time where you can get the most offensive/defensive and compliance value.

Implement technical controls like firewalls and encryption, administrative controls such as policies and training, and physical controls to secure premises. Make sure your mitigation efforts can adapt to the evolving cyber threat landscape. Continuously review and update strategies to stay ahead of potential risks. Proactive measures ensure your organization's security in a connected world.

For mitigation, make sure it is prioritized by risk ratings (like a CVSS score). Critical issues should be table stakes, but for mediums or lower - align them with business timelines. Lastly, make it easy for dev teams to mitigate risks by giving them paved road solutions.

Over decades in the field, I've learned that flexible and adaptive mitigation strategies are crucial. Combine layered security measures to create a robust defense-in-depth strategy. Regularly review and update your security policies to reflect the latest threat intelligence and regulatory requirements. Invest in ongoing training programs to keep your team’s skills sharp and up-to-date. Incorporate security into your development lifecycle (DevSecOps) to ensure that security is built into your products from the ground up. The key is to remain agile, continuously adapting your strategies to the ever-evolving cyber threat landscape.

Reflecting on decades of experience, it's clear that a strong cybersecurity culture is fundamental. Cultivate an environment where security is everyone’s responsibility. Encourage transparent communication about threats and vulnerabilities. Recognize and reward proactive security behaviors. Additionally, consider the human element in your strategies—invest in psychological and behavioral training to help employees recognize social engineering and phishing attacks. Finally, stay ahead by continuously learning and adapting, ensuring that your cybersecurity practices evolve with the changing landscape.
