TCP-SYN Flooding Attack in Wireless Networks

This paper concerns the TCP (Transmission Control Protocol) vulnerabilities which gives space for a DoS (Denial of Service) attacks called TCP-SYN flooding which is well-known to the community for several years. The paper shows this attack in wireless as well as wired networks using perl synflood script, Wireshark network analyzer server, Windows 2008 server, and OPNET simulation environment. Using these tools an effects of this attack are shown. Finally, some effective practical mitigation techniques against SYN flooding attack for Linux and Windows systems are explained

Analysis of the SYN Flood DoS Attack

The paper analyzes systems vulnerability targeted by TCP (Transmission Control Protocol) segments when SYN flag is ON, which gives space for a DoS (Denial of Service) attack called SYN flooding attack or more often referred as a SYN flood attack. The effects of this type of attack are analyzed and presented in OPNET simulation environment. Furthermore, the paper presents two anomaly detection algorithms as an effective mechanism against this type of attack. Finally, practical approaches against SYN flood attack for Linux and Windows environment are shown

Intrusion Detection System on Suricata with Bot Telegram as A Notification System

The Intrusion Detection System (IDS) is a type of security system that serves as a protective layer for an organization's information technology infrastructure. IDS technology has evolved tremendously over the years to keep pace with the development of cybercrime. There are many instances when an IDS is bypassed by a novel kind of attack, and a substantial proportion of normal packets are classified as attack packets. This may result in more serious problems if the administrator is not constantly monitoring the network and is unaware of the attack. And by the time they understand it, it is too late
