Abstract [en]

As the connectivity of home devices elevates so does the volume and sophistication of cyber attacks consistently grow. Therefore, the need for network security and availability becomes more significant. Numerous sorts of countermeasures like firewalls and router-based packet filtering have been put in place, although these alone are not enough to brace the network from unauthorised access. One of the most efficient methods of stopping network adversaries is using Intrusion Detection and Prevention Systems (IDPS). The goal of an IDPS is to stop security attacks before they can be successfully carried out. In this paper, I looked at four network attacks namely; probing, denial of service, remote to user and user to root and improved their respective Snort rules to optimize processing time and capturing capacity using regular expressions and fast pattern. Snort with improved rules captured 100% of the attacks launched to the network while without the improved rules, Snort captured between 0% to 60% of the attacks launched to the network making an improvement of 40%.
