A sniffer is a software or hardware tool that allows users to monitor internet traffic in real-time. It has various benefits such as monitoring network traffic, identifying invalid nodes, and debugging application traffic. But sniffers have downsides as well. Cybercriminals use sniffers to tap into a network and capture confidential information.
Various types of sniffers are available and more are being created every day. Hence sniffing is among the easiest hacking techniques out there. But a few precautions on your part can help enhance your data security and prevent sniffing attacks.
Preventing sniffing attacks
You can prevent sniffing attacks by taking a few precautionary measures that can make it challenging for the hackers to either tap into your network traffic or peek into the data that is being transmitted.
Encrypt your Communication with a VPN
Sniffing attacks are performed to collect information that is transmitted over the network. Hence you can prevent sniffing attacks by encrypting all the communication that is received or sent over your network. Encrypting communication will increase security and prevent sniffing attacks as cybercriminals will have to decrypt the packet to get the information they want. You can use secure VPN services to encrypt your communications.
Route public WiFi requests to head office firewall
Connecting to unsecured networks can increase chances of sniffing attacks, but in this age when remote working is becoming the norm, it is challenging to monitor every connection request. Leveraging services that can route all network requests to your head office firewall can help you prevent sniffing attacks through unsecured networks. For instance, you can use an Enterprise Cloud solution that can route all the network requests to your head office firewall, where you can apply security policies and protocols to all the requests and secure your connection.
These are some of the ways to prevent data leaks caused by sniffing attacks. You can also use context-based data leak prevention solution to further improve your data security. Context-based data leak prevention firewall can create context around your data for deep inspection and complete control over data packets.
