Packet sniffer software#
Such software and hardware does not completely eliminate the threat, but like many network security tools, they are part of the overall system.
A switched infrastructure obviously does not eliminate the threat of packet sniffers, but it can greatly reduce their effectiveness.Īntisniffer tools-Employing software and hardware designed to detect the use of sniffers on a network. For example, if an entire organization deploys switched Ethernet, hackers can gain access only to the traffic that flows on the specific port to which they connect. ■ Switched infrastructure-This can be used to counter the use of packet sniffers in your network environment. Sniffers deployed to learn sensitive information (such as mail messages) will still be effective. Note that this mitigation technique is effective only against a sniffer implementation that is designed to grab passwords.
Packet sniffer password#
If a hacker learns that password by using a packet sniffer, the information is useless because the password has already expired. A user combines that random password with a PIN to create a unique password that works only for one instance of authentication. A token card is a hardware or software device that generates new, seemingly random, passwords at specified intervals (usually 60 seconds). With OTPs you need a PIN and your token card to authenticate to a device or software application. A customer needs both an ATM card and a personal identification number (PIN) to make transactions. Automated teller machines ( ATMs) use two-factor authentication. Two-factor authentication involves using something you have combined with something you know. A common example of strong authentication is one-time passwords (OTPs).Īn OTP is a type of two-factor authentication. Strong authentication can be broadly defined as a method of authenticating users that cannot easily be circumvented. ■ Authentication-Using strong authentication is a first-option for defense against packet sniffers. The following techniques and tools can be used to mitigate packet sniffers: Cryptography-The most effective method for countering packet sniffers does not prevent or detect packet sniffers, but rather renders them irrelevant.Antisniffer tools-Use these tools to employ software and hardware designed to detect the use of sniffers on a network.Switched infrastructure-Deploy a switched infrastructure to counter the use of packet sniffers in your environment.Authentication-A first option for defense against packet sniffers is to use strong authentication, such as one-time passwords.Import and export packets in a number of formats.The following techniques and tools can be used to mitigate sniffers:.Create, customize, and send your own wireless packets through your adapter to test firewalls, intrusion detection systems, or protocol compliance.Browse captured and decoded packets in real time.Reconstruct TCP sessions and UDP data streams.Specify WEP or WPA keys to decrypt encrypted packets.Scan the air for WiFi stations and access points.By providing this information, CommView for WiFi can help you view and examine packets, pinpoint network problems, and troubleshoot software and hardware. This application captures every packet on the air to display important information such as the list of access points and stations, per-node and per-channel statistics, signal strength, a list of packets and network connections, protocol distribution charts, etc. Loaded with many user-friendly features, CommView for WiFi combines performance and flexibility with an ease of use unmatched in the industry.
