How Machine Learning is Used in IT Security
Machine Learning is said to revolutionize the economy. In the field of IT security, new challenges will arise on the one hand, and new opportunities will emerge on the other. Even today, Machine Learning can contribute to strengthening IT security within a company.
For many, terms like Artificial Intelligence, Deep Learning, and Machine Learning may seem quite abstract. However, they are already an integral part of companies’ IT security concepts. In particular, the General Data Protection Regulation (GDPR) has accelerated this development. Learn here where Machine Learning already plays a significant role in IT security.
1. Predicting Threats
Machine Learning enables the collection and analysis of data to predict fraudulent activities. This can help the IT department identify dangers early and thus prevent serious and costly data protection breaches and thefts.
2. Structuring Threats
To structure threats, efficient analysis is required. Machine Learning analyzes attack methods in such a way that the various aspects of the attack can be classified. Through this clustering, the IT department can build its IT security structure much more specifically to its own requirements and react to changes.
3. Error Analysis
Many companies have already experienced incidents. Machine Learning can trace these and thus completely close the obvious gaps. Patterns and associations are traced, and recommendations for risk mitigation are created based on this.
4. Penetration Testing
Penetration testers, in the original sense, are individuals who deliberately attempt to attack a company’s IT security to identify potential vulnerabilities. Particularly for smaller companies, Machine Learning-based programs can provide a more cost-effective solution to achieve this.
It is clear that Machine Learning can help build IT security more efficiently and reliably. This allows IT departments to focus more precisely on real threats. After all, it should be clear: Many of these measures are based on the interplay between humans and software. Only if IT departments draw the right conclusions from the data and analyses provided, can Machine Learning truly help.
Key Facts
AI in Cybersecurity: The market for AI-driven security grows annually by 24 percent.
Deepfake Threat: The number of deepfake attacks on companies increased by over 300 percent in 2024/2025.
Frequently Asked Questions
What penalties are imposed for GDPR violations?
Fines of up to 20 million Euros or 4 percent of global annual turnover – whichever is higher. Additionally, there may be compensation claims from affected individuals.
What is a Data Protection Impact Assessment?
A DPIA is a systematic evaluation of the risks of data processing for the rights and freedoms of the individuals concerned. It is mandatory if the processing is likely to pose a high risk – for example, in profiling, video surveillance, or the processing of special data categories.
Does the GDPR apply to small businesses?
Yes, the GDPR applies to every company, regardless of size, that processes personal data of EU citizens. Small businesses benefit from a few simplifications (e.g., no processing register for fewer than 250 employees in non-risky processing), but must adhere to all basic principles.
