VYSOKÁ ŠKOLA POLYTECHNICKÁ JIHLAVA Katedra technických studií Návrh bezpečnostní politiky filtrování webového provozu ve školním prostředí bakalářská práce Autor práce: Radek Kudrna Vedoucí práce: Mgr. Antonín Přibyl Jihlava 2020 ZADÁNÍ BAKALÁŘSKÉ PRÁCE Autor práce: Radek Kudrna Studijní program: Elektrotechnika a informatika Obor: Aplikovaná informatika Název práce: Návrh bezpečnostní politiky filtrování webového provozu ve školním prostředí Cíl práce: V teoretické části diskutujte návrh bezpečného přístupu k Internetu pro žáky škol včetně návrhu monitoringu přístupů, na druhou stranu je potřeba zvážit politiku nefiltrovaného přístupu k Internetu. Diskutujte právní fakt nemožnosti delegace právní odpovědnosti na nezletilé žáky, která souvisí s provozem školních (bezdrátových) sítí. V praktické části bude provedeno nasazení Kerio Control s Active Directory pro filtrování provozu na MŠ a ZŠ Brtnice. Mgr. Antonín Přibyl doc. Ing. Zdeněk Horák, Ph.D. vedoucí bakalářské práce vedoucí katedry Katedra technických studií Abstrakt Tato bakalářská práce se zabývá problémem přístupu k internetu pro školy, zejména pro základní školy. Při nefiltrovaném obsahu jsou nezletilí žáci vystaveni určitým rizikům. Jedná se především o přístup na stránky se závadným obsahem, možností stát se kybernetickou obětí, nebo k samotné možnosti páchání trestné činnosti přes školní internet. Pro zamezení těchto činností je nutnost zavést určitou bezpečnostní politiku v podobě filtrování webových stránek. Právě jednotlivé možnosti blokování stránek jsou v práci popsány. Součástí je i ukázka a popis řešení v nástroji Kerio Control, který je nasazen na filtrování provozu na základní a mateřské škole Brtnice. Klíčová slova filtrování provozu; Kerio Control; monitoring; nezletilí žáci; webový filtr Abstract This bachelor thesis deals with the problem of Internet access for schools, especially for primary schools. -

Testing Anti-Virus in Linux: How Effective Are the Solutions Available for Desktop Computers?
Royal Holloway University of London ISG MSc Information Security thesis series 2021 Testing anti-virus in Linux: How effective are the solutions available for desktop computers? Authors Giuseppe Raffa, MSc (Royal Holloway, 2020) Daniele Sgandurra, Huawei, Munich Research Center. (Formerly ISG, Royal Holloway.) Abstract Anti-virus (AV) programs are widely recognized as one of the most important defensive tools available for desktop computers. Regardless of this, several Linux users consider AVs unnec- essary, arguing that this operating system (OS) is “malware-free”. While Windows platforms are undoubtedly more affected by malicious software, there exist documented cases of Linux- specific malware. In addition, even though the estimated market share of Linux desktop sys- tems is currently only at 2%, it is certainly possible that it will increase in the near future. Considering all this, and the lack of up-to-date information about Linux-compatible AV solutions, we evaluated the effectiveness of some anti-virus products by using local installations, a well- known on-line malware scanning service (VirusTotal) and a renowned penetration testing tool (Metasploit). Interestingly, in our tests, the average detection rate of the locally-installed AV programs was always above 80%. However, when we extended our analysis to the wider set of anti-virus solutions available on VirusTotal, we found out that the average detection rate barely reached 60%. Finally, when evaluating malicious files created with Metasploit, we verified that the AVs’ heuristic detection mechanisms performed very poorly, with detection rates as low as 8.3%.a aThis article is published online by Computer Weekly as part of the 2021 Royal Holloway informa- tion security thesis series https://www.computerweekly.com/ehandbook/Royal-Holloway-Testing-antivirus- efficacy-in-Linux. -
