  The security of the service and the system depends on the security of each of
them components of this system. An attack on the routing protocol may be
inaccurate functioning of the computer network. In some cases this is possible
The attacker comes to data or artificial information for which he is not
entitled. OSPF protocol is the most commonly used connection protocol. U In
this paper, we conducted an OSPF security analysis and described it security
mechanisms.
  ----- Bezbednost nekog servisa i sistema zavisi od bezbednosti svake
komponente tog sistema. Napad na protokol rutiranja mo\v{z}e proizvesti
neispravno funkcionisanje ra\v{c}unarske mre\v{z}e. U pojedinim slu\v{c}ajevima
mogu\'ce je da napada\v{c} do{\dj}e do podataka ili umetne podatke za koje nema
pravo. OSPF protokol je najrasprostranjeniji protokol stanja linka (link-state
protocol). U ovom radu izvr\v{s}ili smo analizu bezbednosti OSPF protokola i
opisali njegove bezbednosne mehanizme.
