This month of October celebrates Cybersecurity Awareness Month and it seems like the best time to talk about cybersecurity. Indeed, with the spread of the pandemic, organizations have never been so exposed to cyber threats. Not only can they suffer severe service disruptions and reputational damage, but they can also lose personal data, which can lead to significant fines from regulators. All of this can be devastating for a business.

The risks of cyberattacks are not new, but they are becoming more sophisticated and persistent. This is why organizations need both cybersecurity and cyber resilience.

What is cyber resilience?

Cyber ​​resilience is a company’s ability to mitigate damage and continue once systems or data have been compromised. It covers both adversarial threats (hackers) and non-adversarial threats (human error). Cybersecurity, on the other hand, is the ability of a business to protect itself against and avoid cyberthreats. A cybersecurity strategy is to minimize the risk of attacks while cyber resilience is designed to minimize the impact.

An effective cyber resilience program included a programmatic approach to resisting disruptive cyber incidents. To ensure that the model is effective, it must predict, prioritize and practice. The objective is to be able to anticipate a fault rather than to react to it because it is necessary to prioritize the threats. Not all vulnerabilities require the same attention.

Additionally, a cyber resilience program should have a governance framework with policies, procedures, and accountability built into the business strategy. Therefore, if kept up-to-date for its relevance to new threats, the model should be more effective within an organization.

How does this work?

Cybersecurity in a business ensures that all devices are running the latest firmware, that firewalls, VPNs, and anti-virus/malware protection are up and running, that all software and tools are patched, and that all employees are up to date. aware of potential threats and how to deal with them.

Cyber ​​resilience varies from company to company. A good way to start is to identify where cyber incidents could cause the most damage to the business, in order to understand how service continuity could be affected.

A strong cyber resilience program ensures business continuity with minimal business impact despite an incident. It is a process that provides the means of recovery after an attack. This is done, first, by measuring and getting to know assets and infrastructure well and, second, by configuring key security settings, managing access permissions, and regularly updating software. Next, the organization must put in place systems and processes to detect vulnerabilities before attackers and prioritize the most important threats.

Threat Intelligence should be flexible and should allow the user to drill deeper into threats to better understand their origin, delivery mechanism, actors, potential victims, attack vectors, TTPs and data they are accessing . A threat intelligence program must also ensure that stakeholders can enforce policies for better integrity and business continuity.

The concept of “digital twin” is important in cyber resilience. Having a simulated digital model of the business or process will help understand the impact on overall production and efficiency.

Knowing how everything could be affected helps in taking the appropriate steps to mitigate the damage as much as possible in the event of an attack. Additionally, having a strong cyber incident response plan is essential as it will be implemented in the event of an incident and the response team can act quickly and accordingly.

Conclusion

Cybersecurity is a good way to start protecting a business, however, with ever-evolving cyber threats, it is necessary to be even more prepared. This is why cyber resilience is now necessary.

Cybersecurity and cyber resilience work best together and require a significant investment of time, resources and education, but will be worth it.
