`In a digital landscape where cyberattacks are becoming increasingly sophisticated and disruptive, businesses need to evolve from merely preventing breaches to ensuring resilience. Cyber resilience focuses on a business's ability to anticipate, withstand, recover from, and adapt to cyber incidents. Learning from recent high-profile attacks offers critical lessons on how businesses can enhance their security posture and minimize downtime or damage when targeted. Here are the top five new lessons every business should apply to build a cyber-resilient organization.
1. Embrace Proactive Threat Hunting
Relying solely on defensive security measures is no longer enough. Recent attacks, like those on major technology companies, have shown that waiting for alerts or anomalies to surface can lead to delayed responses and increased damage. Proactive threat hunting involves continuously searching for suspicious activity and signs of compromise within the network, even before an attack manifests.
In the case of the Microsoft Exchange Server breach in 2021, proactive threat hunting by cybersecurity researchers and companies identified vulnerabilities before many organizations even knew they were at risk. This allowed those organizations to implement fixes or mitigations sooner.
To implement proactive threat hunting:
Create a dedicated security operations team tasked with identifying potential threats before they become incidents.
Utilize advanced tools, such as endpoint detection and response (EDR) and extended detection and response (XDR), to monitor real-time activities across the network.
Regularly assess the network for indicators of compromise (IoC) and unknown threats.
Collaborate with external threat intelligence providers to stay informed about emerging threats in your industry.
2. Invest in Cyber Insurance
Cyber insurance has become a critical component of cyber resilience. No matter how secure a business may be, the potential for breach still exists, and when incidents do occur, the costs can be staggering. High-profile ransomware attacks, such as the Colonial Pipeline attack, demonstrate how expensive recovery efforts can be, both in terms of ransom payments and operational downtime.
Cyber insurance can help mitigate financial losses associated with breaches, covering aspects such as data restoration, public relations damage control, regulatory fines, and legal costs. However, businesses must ensure they meet the security criteria set by insurers to qualify for coverage.
When considering cyber insurance:
Choose policies that align with your industry’s specific risks and needs.
Ensure your insurance covers both first-party losses (business disruption, data recovery) and third-party liabilities (customer lawsuits, regulatory penalties).
Regularly review and update your policy to reflect the evolving threat landscape.
Consider insurance as part of a broader risk management plan, rather than relying on it as the sole line of defense.
3. Strengthen Endpoint Security
In the era of remote work and BYOD (Bring Your Own Device), endpoint security has become one of the most crucial aspects of cybersecurity. Cybercriminals often exploit vulnerable devices, such as employee laptops or mobile phones, to gain access to corporate networks. The 2020 Twitter breach, which compromised high-profile accounts, is an example of how attackers exploited endpoints (employee devices) to carry out social engineering attacks.
To build cyber resilience, businesses need to ensure that all endpoints—whether they belong to employees, contractors, or partners—are secured and monitored continuously.
Key steps for improving endpoint security include:
Implementing device management software that enforces security policies on all devices connecting to the network.
Utilizing encryption for sensitive data on all devices to ensure that even if devices are compromised, data remains secure.
Deploying mobile device management (MDM) solutions to control access to corporate resources on smartphones and tablets.
Enforcing stringent password and biometric authentication practices on all devices.
4. Adopt a Continuous Backup and Disaster Recovery Strategy
Backup and disaster recovery (BDR) strategies play a pivotal role in ensuring businesses can quickly bounce back from cyber incidents such as ransomware attacks. Several organizations targeted in ransomware campaigns, including hospitals and financial institutions, suffered severe downtime because they lacked proper backup strategies or because their backups were also compromised.
A continuous backup and disaster recovery strategy ensures that businesses can restore operations quickly and efficiently, minimizing financial and operational disruptions.
Key aspects of a strong BDR strategy:
Ensure backups are stored in multiple locations, including offline or air-gapped storage, to prevent attackers from encrypting backups during ransomware attacks.
Automate backup processes to capture real-time changes, reducing the risk of losing valuable data.
Test the recovery process regularly to ensure that backups are functional and can be restored in a timely manner.
Implement a recovery time objective (RTO) and recovery point objective (RPO) to determine the acceptable amount of data loss and downtime after an incident.
5. Enhance Data Governance and Privacy Compliance
In an era of stricter privacy regulations like the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), businesses need to prioritize data governance as a critical component of their cybersecurity strategy. Recent high-profile data breaches, such as those affecting Facebook and Marriott, have resulted in significant fines and reputational damage due to non-compliance with data protection laws.
Building cyber resilience means not only protecting your data but also ensuring that your business complies with relevant data privacy laws and regulations. Effective data governance includes knowing where sensitive data resides, how it’s accessed, and who has permission to use it.
To enhance data governance and privacy compliance:
Implement data discovery and classification tools to automatically identify and categorize sensitive data across your organization.
Enforce role-based access controls (RBAC) to limit who can access certain data, reducing the risk of insider threats and accidental breaches.
Regularly audit data practices to ensure compliance with applicable privacy laws and regulations.
Provide ongoing training for employees on the importance of data privacy and their role in safeguarding sensitive information.
Conclusion
Building a cyber-resilient business is no longer just about preventing attacks—it’s about ensuring that your organization can respond to, recover from, and adapt to evolving threats. The lessons learned from recent high-profile cyber incidents highlight the need for proactive threat hunting, investment in cyber insurance, strengthened endpoint security, continuous backup strategies, and enhanced data governance. By incorporating these lessons into your cybersecurity framework, you can better protect your business, mitigate the risks of an attack, and bounce back stronger after an incident.
