The TCP SYN Flood attack is not a new phenomenon. Its origins can be traced back to the dawn of the internet when network security was in its infancy. As the internet grew in popularity and commercial significance, malicious actors became more motivated to exploit potential vulnerabilities. Early...
Advanced Techniques and Variations While the basic methodology of a TCP SYN Flood remains consistent, there are variations and advanced techniques: Reflection Attacks In a reflection attack, the attacker sends SYN requests to various servers with a spoofed IP address (the victim’s). These servers ...
ARP Cache Poisoning Mitigation Techniques Poisoning ARP cache remotely is bit difficult as it requires either physical access to the network or control of one of the machines in the network. Since its not always easy so ARP attacks are not frequently heard. Anyways, taking precautions is better ...
Analyzing the Exploitability of the Type Confusion Bug Since the debug setup with symbols is now ready, let’s take another look at the crash by setting breakpoints and stepping through the code. Thetcpcbstructure can be inspected during the call totcp_timer_activefunction, wh...
To have a better understanding of the attack dynamics and lead to future mitigation techniques, modeling DoS/DDoS attacks for SDN is necessary. The main goal of modeling is to provide i) better understanding about the attack effect, and consequently ii) more effective mitigation techniques. ...
Note:Configuring VTY access-class filters is not an effective mitigation strategy for this vulnerability. Infrastructure ACLs (iACL) Although it is often difficult to block traffic transiting your network, it is possible to identify traffic which should never be allowed to target your infrastructure ...
Port scan techniques are different for TCP and UDP ports, which is why we have dedicated tools for each one. What are the most common ports? What does a port scanner do? What is the best port scanner online? How long does a port scan take? What are some of the impacts of running...
One potential mitigation to this is a mechanism termed "Limited Trans- mit." With this mechanism, a duplicate ACK may trigger an immediate transmission of a segment of new data. Two conditions are applied to this; the receiver's advertised window allows the transmission of this segment, and ...
Abstract This document discusses both use cases and operational experience with Multipath TCP (MPTCP) in real networks. It lists several prominent use cases where Multipath TCP has been considered and is being used. It also gives insight to some heuristics and decisions ...
often exploit code found in server software that lets them get unauthorized access on the remote machine. port scanning is part of the first phase of a penetration test (reconnaissance) and allows you to find all network entry points available on a target system. port scan techniques are ...
