In terms of IT security, a spoofer is an individual who assumes the identity of another person, program or computer to fool other people, devices, and software into believing they are a trusted source. Typical forms of involve email spoofing, IP spoofing and network spoofing. For the most part, an individual will spoof a network device that is trusted for malicious and damaging purposes, allowing them to access the private files of another network without authorisation.

Understanding network spoofing

Cybercriminals often use network spoofing to gain access to secured networks in order to obtain files or information that may be restricted. The malicious operator will use the IP address of a computer trusted by a network to bypass defences and achieve access. As the device’s IP address is registered as being a legitimate and trusted source, the network’s secure gateway will allow packets of data to be exchanged.

Some useful hints on avoiding network spoofing attacks

When dealing with potential spoof tactics aimed at your enterprise, it is important to remain proactive. The following are some useful steps worth implementing at your firm to remain protected against these insidious attacks.

Packet filters

Packet filtering was designed to examine data packets when in transit. Packet filters can assist IT professionals in preventing IP-based spoof attacks, as they will effectively block data packets using source address details deemed incorrect.

Avoid employing trust relationships

When a network relies solely on IP addresses in order to authenticate a computer it connects with, this is called a trust relationship. By stopping the use of trust relationships, you can create an additional level of security.

Deploying a spoof detector

A wide variety of reliable spoof detection solutions are available that can help to ARP spoof attacks from spreading across networks. These dedicated tools have been devised to inspect incoming data and block it, should be it be identified as illegitimate.

Establish network firewalls

A perimeter defence for your enterprise, a robust firewall can aid you in keeping intruders out of your network.

Install antivirus across your network devices

Deploying this security software on company computers will ensure that they can cope with malicious software should it be downloaded through a network attack.

Maintain employee alertness with awareness training

A key step to preventing network spoofing is remaining aware of potential dangers. To make sure your company remains protected from spoof tactics, always ensure you staff are fully aware of the risks linked to them.
