An Overview of Buffer Overflow and Network Intrusion Detection and Prevention Systems
Publication Date : 01/04/2019
Cyber-crime is becoming a big business run by organised and sophisticated syndicate with varying degree of Information Technology skills targeting computer applications and programs by running arbitrary code execution into the memory of a program to take over the program. The aim of this work is to review how traditional host based protection mechanism like Data Execution Prevention (DEP), Address Space Layout Randomization (ASLR) and Canaries help to detect and prevent these buffer overflow attacks and how their shortcoming led to the development of Network Intrusion Detection and Prevention Systems (NIDPS). Secondary data was used to reviewed relevant available materials in their effort to examine in-depth performance these technologies. It is recommended that combining anomaly-based with fuzzy logic will be a good technology for intrusion detection and efficient performance that can reduced false positive alerts.
