Lessons from Yesterday’s Cyber Outage: Key Takeaways for Robust Cybersecurity
Cyber (or IT) outages can have devastating impacts on businesses, causing not only financial losses but also reputational damage. Yesterday's cyber outage was a stark reminder of the vulnerabilities that lurk within our interconnected systems. As organizations rely increasingly on digital technologies, understanding and mitigating these risks becomes paramount. Reflecting on the recent incident, several critical lessons have emerged that can help organizations fortify their defenses and enhance their incident response strategies. These takeaways highlight the importance of a comprehensive approach to cybersecurity, emphasizing the need for thorough risk assessment, robust change management, and an inclusive incident response plan.
1. Understand the Risks in Your Digital Supply Chain
One of the most crucial aspects of maintaining a secure digital environment is understanding the risks inherent in your digital supply chain or software development life cycle (SDLC). The cyber outage underscored the importance of thoroughly testing changes before large-scale deployments into production. This proactive approach identifies and mitigates potential vulnerabilities early, preventing disruptions and security breaches.
Risk Assessment: Regularly conduct risk assessments to identify and evaluate potential threats within your digital supply chain and SDLC. This includes understanding third-party dependencies and their associated risks.
Testing and Validation: Implement rigorous testing protocols, including penetration testing and vulnerability assessments, to validate changes before deployment. This helps in detecting flaws that cyber attackers could exploit.
Continuous Monitoring: Establish constant monitoring systems to monitor changes and their environmental impacts. This enables real-time detection of anomalies and swift action to mitigate risks.
2. Implement a Robust Change Management Process
A robust change management process is essential for handling unforeseen issues during deployments. The recent outage demonstrated the importance of being prepared to roll back changes that do not go as expected and responding effectively to minimize disruption.
Change Control: Develop a structured change control process that includes detailed documentation, approval workflows, and rollback procedures. This ensures that all changes are tracked and can be reversed if necessary.
Rollback Plans: Prepare rollback plans for every deployment. These plans should be tested regularly to ensure smooth execution in case of an unexpected issue.
Responsive Actions: Train your team to respond quickly and efficiently to unforeseen changes. This includes having a clear communication plan to inform stakeholders about the status and impact of the change.
3. Develop a Comprehensive Incident Response Plan
Having an incident response plan that encompasses the entire business is vital. Cyber incidents can affect various aspects of operations, IT, cybersecurity, development, and other business functions. An inclusive incident response plan ensures that everyone knows their role and can contribute to a coordinated response.
Holistic Planning: Create an incident response plan that involves all business functions. Ensure that all team members clearly define and understand roles and responsibilities.
Decision Trees: Develop decision trees to guide actions during different incidents. This helps make informed decisions quickly, even when the nature of the incident is unclear.
Regular Drills: Conduct incident response drills to ensure all team members are prepared to act swiftly and effectively. These drills should simulate malicious and non-malicious incidents to cover all potential scenarios.
Conclusion
Yesterday’s cyber outage powerfully reminds us of the importance of robust cybersecurity practices. By understanding and mitigating risks in your digital supply chain, implementing a solid change management process, and developing a comprehensive incident response plan, organizations can significantly enhance their resilience against cyber threats. Proactive preparation and continuous improvement are vital in maintaining a secure and reliable digital environment.

Secure Cloud Infrastructure Before Deployment
The reliance on the cloud and infrastructure as code (IaC) to streamline development lifecycles has become crucial to every organization’s business. Yet, developers aren’t following security best practices before pushing to production, which increases risk. If unknown vulnerabilities are moved into production, taking the environment down will disrupt business continuity or force the organization to take on more risk.
•Scans IaC repositories to programmatically detect cloud infrastructure misconfigurations and vulnerabilities in the software development lifecycle's design and build phases.
•Leverages 500 prebuilt policies for IaC scanning
•Prevents misconfigurations and vulnerabilities from reaching cloud instances
•Provides a proactive approach to vulnerability assessment for cloud workloads
•Scan for disruptive and costly vulnerabilities before code is deployed.
•Prevent the downtime and additional costs and resources associated with remediating code after deployment
