For the analysis of network traffic and the evaluation of security events, it is necessary to enrich the primary data with additional information related to the monitored traffic. One such piece of data is information about the application or service that generated the intercepted communication. This work will, therefore, focus on identifying the services of IP addresses, URLs, or domains that their operators publish on their sites. To keep the identification up to date, it will be necessary not only to create an initial database but also to update the information obtained regularly.

The aim of the work is primarily:

• Familiarize yourself with network traffic monitoring and web scraping concepts.
• Design a database structure to store service identifiers.
• Choose at least 3 widely used network services and describe how they publish data for identification.
• Design a system architecture for regular downloading of selected data.
• Implement a prototype of the designed system and verify its functionality by filling the database with data.
