Cyber defence measures are a central component of any modern corporate strategy today. Many clients come to us because they are unsure how to truly protect their IT systems. They often report that while they know cyber defence measures are important, they don't know where to start. In this article, we provide impetus and practical examples of how companies can strengthen their security.
Why cyber defences are indispensable
Cyberattacks are becoming increasingly sophisticated and frequent. Companies of all sizes are affected. Small and medium-sized enterprises in particular often underestimate the danger. However, targeted cyber defence measures can prevent major damage.
For example: A medium-sized company was crippled by a ransomware attack. The data was encrypted, and operations ground to a halt. Because the company did not perform regular backups, recovery took weeks. This could have been avoided with simple cyber defence measures such as automated backups.
Another example: A municipality fell victim to a phishing attack. An employee opened a manipulated email and divulged login details. The attackers were then able to access sensitive data. Regular training and clear processes could have prevented this.
Supply chains also present a risk. One manufacturer was weakened by an attack on a supplier. The effects reached far beyond the company affected. Therefore, cyber defence measures must also include partners and suppliers.
Cybersecurity measures in practice
Regular data backup and recovery
Regular data backups form the foundation of any cyber defence measure. Companies should decide which data is particularly important. This data should be prioritised for backups.
For example: An IT service provider backs up customer data daily on an external server. This allows them to get back online quickly after an attack. The data is encrypted and only authorised employees have access.
Another example: a craft business uses a cloud solution for its accounting. The data is automatically backed up. In the event of an attack, it can quickly access the last secure data.
The recovery must also be tested regularly. This is the only way to ensure that the data is actually available in an emergency.
Staff training and awareness
Employees are often the first line of defence. Training helps to raise awareness of cyber defence measures. Employees learn to recognise suspicious emails and react appropriately.
For example: A publisher holds annual training on the topic of phishing. Employees practice identifying dangerous emails. The number of successful attacks has since dropped significantly.
Another example: A hospital regularly trains its staff on password security and data protection. The employees know how to protect sensitive data.
External training courses can also be beneficial. Experts bring new perspectives and practical tips with them.
Technical protective measures and monitoring
Technical protection measures are another important component of cyber defence measures. Antivirus software alone is no longer sufficient today. Companies should use multi-layered security solutions.
For example: a software company uses AI-based tools to detect anomalies in its network. This allows it to ward off attacks early on.
Another example: An energy supplier relies on firewalls and intrusion detection systems. The systems monitor network traffic and issue warnings for suspicious activities.
The monitoring of supply chains is also important. Companies should regularly check whether their partners and suppliers are taking adequate security measures.
BEST PRACTICE at the customer (name hidden due to NDA contract) A medium-sized manufacturer reviewed its entire supply chain after an attack on a supplier. It conducted regular audits and demanded proof of cyber defence measures from its partners. This significantly reduced the risk to its own production. Collaboration with external experts helped to optimise processes and identify new threats early on.
Cybersecurity measures and the role of experts
Implementing cyber defence measures is often complex. Many companies benefit from working with experts. External service providers bring experience and specialised knowledge.
For example, a trading company works with an IT security service provider. The service provider is responsible for system monitoring and incident response.
Another example: A municipality commissions an external consultant to develop an emergency plan. The plan is regularly updated and practised within the team.
Cyber insurance can also be worthwhile. It helps to mitigate financial risks and resume operations quickly after an attack.
My analysis
Cybersecurity measures are essential today. Companies of all sizes are affected. Implementation requires a holistic strategy that considers technical, organisational and human aspects. Regular training, technical protective measures and collaboration with experts are crucial. Only in this way can companies truly protect their IT systems and avoid damage.
