Over the past decade, our world has undergone significant transformations with the advent of connected devices, artificial intelligence, IoT, and cloud services. These technological advancements have brought about numerous benefits, such as increased efficiencies and revenue growth. However, they have also introduced a new set of challenges, with cyber threats being one of the most prominent among them.

Cybersecurity is a multifaceted subject that involves controls, user authentication, processes, policies, and adherence to an ever-expanding list of standards. Misunderstood risks can lead to significant consequences. To ensure business continuity, it is crucial for senior executives to have a fundamental knowledge of cybersecurity. They must prioritize risk management while embarking on the cybersecurity journey and provide the board with meaningful metrics to make informed decisions about cybersecurity investments.

Actions to Begin the Cybersecurity Journey:

A] Governance:

Implementing good governance starts with creating a culture of security from the highest levels of the organization. Emphasize security by design, where security is embedded into every process to ensure a successful implementation of security measures.

B] Understanding Obligations:

Be aware of fiduciary risks, understanding your duty of care and confidentiality in terms of cybersecurity events. Additionally, comprehend contractual obligations based on your industry, regulatory compliance requirements, and data protection regulations before starting your cybersecurity journey.

C] Understanding Risk:

Conduct a maturity assessment or gap assessment of your facility to determine your current cybersecurity posture and desired state, based on industry standards. This high-level assessment will provide you with a risk mitigation strategy and a roadmap for your cybersecurity framework. Key concepts to understand during the risk assessment include risk appetite, risk tolerance, and residual risk.

D] Risk Registry:

Recreate a risk registry to document cybersecurity risks specific to your organization. Include essential details such as risk descriptions, likelihood, potential impact severity (high, medium, or low), mitigation strategies, and contingency plans.

E] Cybersecurity Plan/ Strategy Objectives:

The security program should define policies, procedures, and infrastructure to protect the organization and enable the following:

1. Identify top risks and control access to confidential information and critical systems.

2. Meet legal and regulatory obligations.

3. Manage risks associated with the supply chain.

4. Allocate budgets and resources based on risk assessments.

5. Identify unauthorized activity within the organization’s IT and OT environments.

6. Respond to unauthorized activity promptly to mitigate its impact.

7. Recover from unauthorized activity and restore normal operations.

8. Establish a cycle of continuous improvement through root cause analysis and recommendations.

9. Conduct periodic audits for ongoing evaluation.

Implementation Strategies as Recommended by Cybersecure Canada:

As per industry standerds recommends 13 baseline controls that are applicable to small and medium businesses worldwide. Some of these strategies include:

1. Asset and Data Defense:

Understand the scope and focus on critical assets and data for deploying applicable controls. Create an inventory list of all assets, including hardware, software, and their respective OS/firmware and software revisions. This visibility helps identify obsolete and vulnerable systems, allowing the organization to implement appropriate controls, such as auto patch management, antivirus, system hardening, and isolation of unpatchable systems.

2. Access Control & Authorization:

Implement access control measures like least privilege, password policies, multi-factor authentication (MFA), centralized authorization control systems, and limited remote access.

3. Backup & Encrypt Data:

Regularly back up data and ensure encryption for added security. Test the restore function of backups to verify their effectiveness.

4. Secure Remote Access:

Limit remote access to virtual private networks (VPNs) and use multi-factor authentication for added security.

5. Basic Perimeter Defense:

Deploy firewalls, segment networks, use secure Wi-Fi (preferably WPA2-Enterprise), and avoid connecting public Wi-Fi networks to the corporate network. Implement Domain-based Message Authentication, Reporting, and Conformance (DMARC) for email services.

6. Employee Awareness and Training:

Regularly conduct phishing campaigns, cyber hygiene training, and awareness programs for all employees to strengthen the organization’s overall security posture.

7. Incident Response Plan:

Develop a written incident response plan and designate a dedicated incident response team to handle cyber incidents effectively.
