This study aims to examine the vulnerabilities of the wireless network of an educational institution by conducting controlled penetration attacks. The central objective is to identify and analyze the main weaknesses of the wireless network infrastructure in order to suggest improvement measures to ensure confidentiality, integrity and availability of information. The plan was based on the PTES penetration testing methodology, and each phase was meticulously carried out, documenting every important aspect to ensure a complete evaluation. The results and conclusions focused on improving the security of wireless networks, reducing identified risks and strengthening cyber defenses against future threats. The research conducted, in addition to emphasizing the importance of network security in an educational environment also provides a practical and detailed model for assessing the security of wireless networks.
