As a business leader or C-Level executive in New Zealand, you’re aware that cybersecurity is a pressing concern. With the increasing prevalence of cybercrime and the ever-expanding attack surfaces, it’s crucial to take proactive steps to protect your organisation. If you’re unsure where to start or what a cybersecurity strategy entails, you’re not alone. In this article, we’ll outline key steps to help you begin your cybersecurity journey, starting with vulnerability scanning—a vital first step.

Identifying the Problem

The ever-evolving threat landscape and the potential for cyberattacks to cost millions and make headlines have heightened the need for effective cybersecurity measures. However, not knowing where to start can be overwhelming. Understanding the significance of vulnerability scanning and its role in cybersecurity can pave the way for a robust defence against cyber threats.

Steps to Take

Recognise the Importance of Vulnerability Scanning:

Vulnerability scanning is a proactive approach to identify weaknesses and security gaps in your organisation’s digital infrastructure. It involves assessing your systems, networks, and applications to uncover vulnerabilities that could be exploited by malicious actors. By conducting regular vulnerability scans, you can stay one step ahead of potential cyber threats.

Embrace a Four-Phase Vulnerability Management Approach:

To effectively manage vulnerabilities, it’s essential to adopt a comprehensive three-phase approach: identification, prioritisation, and remediation. Each phase plays a crucial role in strengthening your organisation’s cybersecurity defences.

Phase I: Assess – Identify Vulnerabilities:

Utilise scanning tools and methodologies to discover and document vulnerabilities in your systems, networks, and applications. This process helps you gain a clear understanding of potential security risks.

Phase II: Analyse – Prioritise Vulnerabilities:

Once vulnerabilities are identified, prioritise them based on criticality, impact on your organisation, and potential exploitation. Consider asset criticality, actively exploited vulnerabilities, and the likelihood of an attack to determine which vulnerabilities need immediate attention.

Phase III: Advise – Plan to Remediate Vulnerabilities:

Develop a robust remediation plan to address identified vulnerabilities. Ensure efficient patching, fixing, or updating of systems to eliminate security gaps. Automation tools can simplify this process and reduce the risk of human error.

Phase IV: Activate – Take Proactive Steps

Once you have identified and addressed vulnerabilities in your organisation’s cybersecurity, it’s time to move on to the final phase: Activate. This phase focuses on taking proactive steps to strengthen your overall cybersecurity posture and ensure ongoing protection.

Key Things to Know:

Seek Alignment between IT and Cybersecurity Teams:

Collaboration between your IT and cybersecurity teams is vital in vulnerability management. Both teams should work together to identify, prioritise, and remediate vulnerabilities. While IT operations often lead vulnerability identification, cybersecurity professionals play a crucial role in providing threat intelligence and ensuring alignment with business risk.

In this collaborative effort, a Chief Information Security Officer (CISO) or a virtual Chief Information Security Officer (vCISO) can play a crucial role in aligning IT and cybersecurity teams and ensuring a comprehensive understanding of business risk. Here’s how they can be useful in this regard:

• Bridge the Gap: A CISO/vCISO facilitates communication between IT and cybersecurity teams, bridging the gap between technical and risk perspectives.
• Business-Focused Approach: A CISO/vCISO considers business objectives and risk appetite, aligning cybersecurity with the overall strategy.
• Risk Assessment and Prioritisation: CISOs/vCISOs conduct comprehensive risk assessments, identifying vulnerabilities and prioritising mitigation efforts.
• Strategic Planning: CISOs/vCISOs develop cybersecurity plans that integrate with IT initiatives and support business goals.
• Governance and Compliance: CISOs/vCISOs ensure compliance with regulations, guiding the implementation of necessary controls and practices.
• Training and Awareness: CISOs/vCISOs promote cybersecurity awareness through training sessions for teams and employees.
• Incident Response and Recovery: CISOs/vCISOs lead incident response, coordinating with IT teams to contain breaches and ensure swift recovery.

A CISO/vCISO with business acumen and a holistic risk perspective aligns IT and cybersecurity teams, preparing the organisation to address cyber threats while maintaining a solid business foundation.

Move towards Automated Vulnerability Management:

It’s crucial to recognise that cybercrime never sits still. A one-time vulnerability test only provides a snapshot of that specific point in time. To effectively manage vulnerabilities, it’s best practice to continually scan and assess your systems. Here’s how you can enhance your vulnerability management approach:

Embrace Automation: By reducing manual processes and leveraging automation tools, you can streamline vulnerability management. Automation simplifies routine tasks like patch management and vulnerability-to-patch correlation, freeing up your teams to focus on more strategic security initiatives.

Continuous Scanning: Implement continuous scanning solutions that regularly assess your IT infrastructure for vulnerabilities. These tools can identify new vulnerabilities as they emerge and provide real-time insights into potential risks.

Patch Management Automation: Automate the process of applying patches to your systems promptly. This ensures that known vulnerabilities are addressed efficiently, minimising the window of opportunity for attackers.

Vulnerability Tracking and Remediation: Utilise automated systems to track and prioritise vulnerabilities based on their severity and potential impact. This enables your teams to effectively allocate resources and address the most critical vulnerabilities first.

Integration with Threat Intelligence: Integrate automated vulnerability management tools with threat intelligence platforms to enhance the identification and prioritisation of vulnerabilities based on real-world threats.

Reporting and Analytics: Leverage automated reporting and analytics capabilities to gain comprehensive visibility into your organisation’s vulnerability landscape. These insights enable you to make data-driven decisions and allocate resources effectively.

By moving towards automated vulnerability management, you can ensure that your organisation remains proactive in addressing emerging cyber threats. Continuous scanning, automation of patch management, and integration with threat intelligence enhance your ability to detect and remediate vulnerabilities, reducing the overall risk to your systems.

Regularly Update and Refine Your Vulnerability Management Practices:

Stay updated on the latest vulnerability management practices, tools, and methodologies. Technology and threat landscapes evolve rapidly, so continuously improving your approach is critical. Regularly assess and refine your vulnerability management processes to adapt to emerging threats.

Conclusion:

As a New Zealand business leader, taking charge of cybersecurity is paramount to safeguarding your organisation’s assets and reputation. By starting with vulnerability scanning and embracing a comprehensive vulnerability management approach, you can proactively identify and address security weaknesses. Foster collaboration between your IT and cybersecurity teams, leverage automation, and continuously refine your practices to stay one step ahead of cyber threats. With these essential steps, you can navigate the complex world of cybersecurity and protect your organisation in today’s ever-changing threat landscape.
