With each new day, new technology and tools are introduced to us. In short, the tech world is drastically evolving, and so is the technology used by attackers. Spoofing is one such illegal activity that the attackers use to disguise their identity or communication so that it looks like a trusted and authorized source. The attackers also target the technical components of a network like DNS server, IP address, and ARP service to exploit them.
But how can you prevent these spoofing attacks? Read on to find out.
Spoofing refers to when an authorized user or device is impersonated by an attacker for spreading malware, bypassing access control systems, or stealing data.
For example, Amazon has made domain and email address verification mandatory to prevent spoofing. There are several types of spoofing, but the most common three types are given below:
The attackers connect their MAC address to an authorized IP address that is already on the network.
In this type of spoofing, the attackers send packets all over the network from a fake IP address.
The attacker initiates a threat like a cache poisoning for rerouting traffic.
Here are some of how you can prevent and mitigate spoofing attacks:
If you have devices on a network that only make use of IP addresses for authentication, the authentication control can be bypassed by IP spoofing. Individual applications or users must authenticate connections between the devices. Certain authenticity systems like IPSec, domain authentication, and mutual certificate auth can also be used for this purpose.
Many programs can be utilized for detecting spoofing attacks, especially ARP spoofing. Tools like Arp monitor, NetCut, or Arp Monitor can defend you at a great scale. Including the mentioned ones, other tools can certify and inspect legitimate data before a target machine receives it. These measures can vitally lower the spoofing attacks’ success.
Multiple secure communication protocols like TLS (Transport Layer Security), IPSec (Internet Protocol Security), and SSH (Secure Shell) have been developed by security experts. If used correctly, the protocols authenticate the device or application to which you are connecting and facilitate data encryption in transit. It lowers the risk of spoofing attacks.
The analysis of IP packets is done by packet filtering. It blocks those attacks having conflicting source information. The malicious packets come from outside the network regardless of what their headers say. Thus, it is a great way to remove spoofed IP packets. The attackers have already created techniques to evade simple packet filters. Thus, most of the packet-filter systems provide a Deep Packet Inspection (DPI) feature, which allows the users to define the rules based on the header and the network packets’ content. This ultimately enables you to filter out several IP spoofing attacks.
If an attacker becomes successful in duping the victim, an entire organization could be thrashed with a ransomware attack or might experience damaging and costly data breaches. And ultimately, the company may encounter legal repercussions, suffer reputation loss, and lose customer trust.
Therefore, it is wise to detect and prevent spoofing attacks beforehand. Once you've followed all the steps mentioned above, you will no longer face spoofing attacks.
