Abstract: By implementing computer and network security, the IT industry strives to provide users with a high level of trust and reliability. The main goal is to ensure confidentiality, integrity and availability of data (the so-called CIA triad). However, this process is invariably accompanied by a parallel one - constant attempts to detect weaknesses in the architecture, software or hardware implementation of a given solution or system. Malicious actors often have an advantage, since it is enough to find a single vulnerability, while protection must cover all possible attack vectors. In recent decades, a number of techniques have been developed to overcome established protections and exploit systems. The history of information security abounds with cases of mass data leaks, in which weak protection led to adverse consequences for organizations. The publication examines some security issues when accessing information systems.
