Many companies have transformed their telephone systems into Voice over IP (VoIP) systems. Although implementation is simple, VoIP is vulnerable to different types of attacks. The Session Initiation Protocol (SIP) is a widely used protocol for handling VoIP signaling functions. SIP is unprotected against attacks because it is a text-based protocol ...
The number of smartphone users recently surpassed the numbers of desktop users on Internet, and opened up countless development challenges and business opportunities. Not only the fact that the majority of users are connected using their smartphones, but the number of Internet users in general has popularized the massive use of data-driven applicat...

Over the last decade, video surveillance systems have become a part of the Internet of Things (IoT). These IP-based surveillance systems now protect industrial facilities, railways, gas stations, and even one’s own home. Unfortunately, like other IoT systems, there are inherent security risks which can lead to significant violations of a user’s pri...
Tato diplomová práce se zaobírá problematikou detekce anomálií v sítích. V teoretické části jsou sepsány metody, které využívající statistický přístup, až po metody strojového učení. Následně je vybrána jedna z popsaných metod. V rámci dané metody došlo ke zvolení dvou algoritmů, \textit{Isolation Forest} a \textit{Local Outlier Factor }. Bylo vytv...
