Abstract:Diplomska naloga obravnava osnovno varovanje stikal z implementiranimi mehanizmi operacijskega sistema IOS. V začetnih poglavjih smo opisali teorijo varnostnih načel, tveganj in kriptografije, ki jih je potrebno upoštevati pri varnosti stikal. Nato smo opisali kako konfigurirati gesla in verificirati delovanje IOS-a. Sledi opis tipičnih napadov na stikala npr. napad na posredovalno tabelo, napad na protokol vpetega drevesa, ter opis ranljivosti navideznega lokalnega omrežja. Predstavili smo tudi ustrezno zaščito pred temi napadi. Nato smo opisali sezname za kontrolo dostopa in podrobneje predstavili avtentikacijo, odobritev in beleženje. V sedmem poglavju smo opisali praktično izvedbo varovanja stikal.

Title:SWITCH BASIC SECURITY FUNCTIONS IMPLEMENTED IN THE IOS OPERATING SYSTEM
Abstract:This thesis discusses the basic protection of switches with implementary mechanisms in the IOS operating system. In the early chapters we described the theory of security principles, risks and cryptography that need to be accounted for by security switches. Then we described how to configure passwords and how to verify IOS operation. What follows is a description of typical attacks on switches, e. g. an attack on a forwarding table or an attack on a spanning tree protocol and a description of vulnerability of a virtual local area network. We also introduced a suitable protection method against these attacks. Then we described the access control lists and introduced in detail authentication, authorization and accounting. In the seventh chapter we described a practical implementation of switch security.
Keywords:switch security, VLAN, STP protocol, access control list, authentication, Cisco IOS
