The aim of an effective cyber resilience strategy is to ensure that a company's business operations remain secure in the event of cyber attacks or data loss. The concept includes security, IT infrastructure, business processes and business continuity.
Cyber resilience is therefore a preventive measure to comprehensively counteract the effects of malware, insider threats, human error as well as software and hardware errors.
How Cyber Resilience Works: The Four Main Components
1. Threat protection: Measures against malware attacks and data misuse
With the advancement of technologies, the number of sophisticated cyber attacks also increases. Viruses, worms, bots, Trojans or keyloggers, common forms of malware not only have a high potential for damage, they are also extremely versatile. Many strains of malware today have polymorphic capabilities to undermine traditional AV solutions. By changing characteristics, signature-based security solutions do not recognize the file as malicious.
It is therefore important to go beyond simple anti-spam and anti-virus software and incorporate DNS authentication mechanisms into the environment. In addition, Endpoint Detection and Response (EDR) solutions enable, for example, the monitoring of endpoint and network events as well as the recording of the collected information in a central database, which offers further analysis. Using behavior analysis based on machine learning, the data is examined for anomalies such as infrequent processes, unusual or unknown connections, and other suspicious activities. This process can be automated, with anomalies triggering alerts for immediate action or further investigation.
In addition, data security solutions such as Data Loss Prevention (DLP) ensure that sensitive information is not misused or accessed by unauthorized users - be it by external attackers or malicious insiders who steal data for financial or personal reasons or manipulate or delete it as an act of sabotage. DLP tools classify confidential and business-critical data and identify violations of guidelines that have been defined by the company or based on legal regulations such as the GDPR.
2. Recoverability: backup and disaster recovery plan
Disaster recovery enables companies to quickly return to normal business functions after an attack. For example, if a sophisticated ransomware attack encrypts business-critical data, the recovery of the data is not guaranteed, even if a ransom is paid. Therefore, regular and thorough backups should be carried out on a separate network, with which all lost data can be restored.
Similar to a fire protection exercise, the training simulation of a data security breach also helps to strengthen cyber resilience. This should go through all the steps that the company takes in the event of a security incident - from escalating the incident by the IT team to communicating with customers to informing the law enforcement authorities.
3. Adaptability
Since cyber criminals are constantly developing new methods of evading detection through security measures, it is important that the company-wide infrastructure can be adapted and further developed in order to be prepared against future threats. The security team needs to be able to identify a security breach and respond quickly to prevent attacks. In addition, there must be integrated administrator tracking in order to identify infected or endangered users. Adaptability is a key component of cyber resilience. If the security team has regular awareness-raising measures such as user training, if it effectively detects threats, and if automation is integrated to eliminate them, a company has come a big step closer to an efficient cyber resilience framework.
4. Longevity
The longevity of a company-wide cyber resilience is not only determined by the IT environment, but also by the company's ability to continue to operate successfully after a cyber attack. The durability component of cyber resilience is therefore optimized through regular updates and system extensions by the IT team.
Whether cyber attacks by external attackers, sabotage and data theft by insiders, human error or insecure software and faulty hardware - the consequences of these threats can be far-reaching for business continuity. Therefore, companies should prioritize the integration of business operations with IT security as part of an effective cyber resilience strategy.
