Cyber defence measures are now a central component of any modern corporate strategy. Many clients come to us because they are unsure how to really protect their IT systems. They often report that although they know cyber defences are important, they don't know where to start. In this article, we provide inspiration and practical examples of how companies can strengthen their security.
Why cyber defence measures are indispensable
Cyber attacks are becoming increasingly sophisticated and frequent. Companies of all sizes are affected. Small and medium-sized companies in particular often underestimate the danger. Targeted cyber defence measures can prevent major damage.
An example: A medium-sized company was paralysed by a ransomware attack. The data was encrypted and operations came to a standstill. 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 local authority was the victim of a phishing attack. An employee opened a manipulated email and disclosed access data. The attackers were then able to access sensitive data. Regular training and clear processes could have prevented this.
Supply chains are also a risk. One manufacturer was weakened by an attack on a supplier. The effects extended far beyond the company affected. Cyber defence measures must therefore also include partners and suppliers.
Cyber defence measures in practice
Regular data backup and restore
Regular data backups are the basis of every cyber defence measure. Companies should decide which data is particularly important. This data should be prioritised for backup.
For example, an IT service provider backs up customer data to an external server every day. 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 backed up automatically. In the event of an attack, it can quickly access the latest secure data.
Recovery must also be tested regularly. This is the only way to ensure that the data is really available in an emergency.
Employee training and sensitisation
Employees are often the first line of defence. Training courses help to raise awareness of cyber defence measures. Employees learn to recognise suspicious emails and react correctly.
For example, a publishing house organises annual training courses on phishing. The employees practise identifying dangerous emails. The number of successful attacks has fallen significantly since then.
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 useful. Experts bring new perspectives and practical tips.
Technical protective measures and monitoring
Technical protection measures are another important component of cyber defence measures. Antivirus software alone is no longer enough. Companies should utilise multi-layered security solutions.
For example, a software company uses AI-based tools to recognise anomalies in the network. This enables it to ward off attacks at an early stage.
Another example: An energy supplier relies on firewalls and intrusion detection systems. The systems monitor data traffic and warn of suspicious activities.
Monitoring supply chains is also important. Companies should regularly check whether their partners and suppliers are taking sufficient security measures.
BEST PRACTICE at the customer (name hidden due to NDA contract) A medium-sized manufacturer reviewed its entire supply chain following an attack on a supplier. It carried out regular audits and demanded proof of cyber defence measures from its partners. This enabled him to significantly reduce the risk to his own production. Collaboration with external experts helped to optimise processes and identify new threats at an early stage.
Cyber defence measures and the role of experts
The implementation of cyber defence measures is often complex. Many companies benefit from working with experts. External service providers bring experience and specialised knowledge to the table.
For example, a retail company works with an IT security service provider. The service provider is responsible for monitoring the systems and responding to incidents.
Another example: A local authority commissions an external consultant to develop an emergency plan. The plan is regularly updated and practised within the team.
Cyber insurance can also be useful. They help to minimise financial risks and resume operations quickly after an attack.
My analysis
Cyber defence measures are indispensable today. Companies of all sizes are affected. Implementation requires a holistic strategy that takes technical, organisational and human aspects into account. Regular training, technical protection measures and cooperation with experts are crucial. This is the only way for companies to truly protect their IT systems and avoid damage.
