Intrusion Detection Systems and Intrusion Prevention Systems

Overview of Intrusion Detection Techniques in Database

Data is one of the most valuable assets in today's world and is used in the everyday life of every person and organization. This data stores in a database in order to restore and maintain its efficiently. Since there is a database that can be exploited by SQL injection attacks, internal threats, and unknown threats, there are always concerns about the loss or alteration of data by unauthorized ...

Intrusion Detection Using Evolutionary Hidden Markov Model

Intrusion detection systems are responsible for diagnosing and detecting any unauthorized use of the system, exploitation or destruction, which is able to prevent cyber-attacks using the network package analysis. one of the major challenges in the use of these tools is lack of educational patterns of attacks on the part of the engine analysis; engine failure that caused the complete training,  ...

Intrusion detection

This paper describes a testing environment for commercial intrusiondetection systems,shows results of an actual test run and presents a number of conclusions drawn from the tests. Our test environment currently focuses on IP denial-of-service attacks, Trojan horse traffic and HTTP traffic. The paper focuses on the point of view of an analyst receiving alerts sent by intrusion-detection systems....

SSH and Intrusion Detection

Widespread use of the SSH protocol greatly reduces the risk of remote computer access by encoding the transmission of clear text usernames and passwords. Prior to the use of SSH, packet sniffing, which allows malicious users to watch for the login process in the clear text packet traffic on a network segment, was an easy method for a malicious user to gain unauthorized access to a machine. Unfo...
