Sniffing attacks prevention and detection techniques

A number of cryptographic protocols have targeted issues related to ARP security. The aim of this research is to detect MAC address spoofing in wireless networks using a hard-to-spoof measurement that is correlated to the location of the wireless device, namely the received signal strength RSS.

The attackers can use a capability that the Windows operating system provides to change the MAC address of a given user. Internal as well as external are of the outmost importance when it comes to information security, but need to be complemented with more depth research for developing detection and prevention mechanisms, and studying internal threats.

However, such mechanisms might not be effective against certain attacks at the lower layers, mainly at the Data Link layer. Besides it is not easily for user to detect the sniffing since this kind of attacks is generating usual traffic over the network. The packets can blend in with valid data communication streams, appearing to be part of the communication, but malicious in nature.

It is a method of attacking an Ethernet local area network by updating the target ARP cache with a forged ARP request and reply packets[9]. ARP mappings may not contain certain IP addresses. Finding IP address conflicts in the Network by verifying if there is another host that has the same IP address and displaying this message: Accordingly a Datalink layer address is known by other names, i.

Furthermore, S-ARP can not prevent against cache poisoning attacks. A recent study[16] showed by experiment the impact of the ARP request update on different Operating Systems. Finally, one device can form two independent clusters, as we explain in the next sections.

The attacker could use a plug-and-play wireless card or a built-in wireless card. However, a recent study[25] shows that only old switches models are vulnerable to this attack. Conversely, the port security[42] features available in recent switches restrict the use of physical ports to configure MAC addresses.

A New MAC Address Spoofing Detection Technique Based on Random Forests

Furthermore, S-ARP can not prevent against cache poisoning attacks. For instance, before authentication takes place i. We identified 4 possible types of abnormal ARP request packets and 6 possible types of abnormal ARP reply packets, as follows: Some researchers have reported that RSS samples from a given sender follow a Gaussian distribution, whilst other researchers revealed that the distribution is not Gaussian [ 2930 ] or that it is not rare to notice non-Gaussian distributions of the samples [ 18 ].

ARP spoofing attacks can be run from a compromised host on the LAN, or from an attacker's machine that is connected directly to the target LAN.

ARP spoofing detection and prevention software The techniques that are used in ARP spoofing can also be used to implement redundancy of network services.

How to prevent network sniffing and eavesdropping

For example. Network Intrusion Detection and Prevention March 15, Benefits of combining three techniques Unknown/new Attacks ¾Not as precise as signature detection, requires human intervention Most customers wish to deploy the IDS in. Oct 25,  · The experiments show what those detection and protection appliances or tools are not fully robust against ARP Spoofing attacks.

In Experiment section underneath, table 4: shows the performance of the security Appliances against 10 different ARP Spoofing attacks. Real-Time Cyber Threat Detection and Mitigation from New York University Tandon School of Engineering.

This course introduces real-time cyber security techniques and methods in the context of the TCP/IP protocol suites.

Explanation of some basic. Sniffing Detection and Prevention techniques: Detecting sniffers can be difficult since they are mostly passive (collects data only) especially in a shared Ethernet. When he is functioning on a switched ethernet network segment it is easier to detect the sniffing using the following techniques, they are –.

Feb 24,  · Many techniques have been proposed to detect MAC address spoofing, as it is a major threat to wireless networks. First, sequence number techniques [ 25, 26 ] track the consecutive frames of the genuine wireless device.
