摘要：at present, an increase in the level of
insecurity due to unauthorized attacks and an increase
in the crime rate. There is hence the need for secure
systems that can ensure high-level security to guarantee
safety and trusted communication. To ensure secure
data communication over the internet and any other
network there is the need to get rid of the threat of
intrusions and misuses. Potential attackers pose great
threats to the information security of the systems. Users
seek to control these threats, recognition of attacks to
increase safety. The attacks that affect a large number of
computers in the world daily can be classified into four
attacks and these include Probing, Denial of Service
(DoS), User to Root (U2R), Remote to User (R2L)
attacks.
Researchers have found the study of attack detection
and prevention of computers from them to be a major
concern throughout the world. Owing to the desire of
many researchers, this paper seeks to propose the idea of
HMM based approach in the detection of Probing, DoS,
U2R and R2L attacks on the system. To accomplish this,
the paper will examine the matter of attack detection in
computer systems, the significance of the computer
security problem in general and attack detection in
specific is also examined. Four salient types of attacks
will then examined in detail to establish how they work.
This will be followed by a brief examination of how
hidden Markov models (HMM) is of use in this context
and finally an investigation of the strategies behind and
various constituent sub-problems of HMM.
