These days, BYOD is the norm. Mobile devices from inside and outside your network are continuously crossing mixed physical and cloud infrastructure whose security may not always be under your control. As a result, your network is being constantly exposed to malware threats. And DNS is their main pathway. More than 90 percent of malware uses DNS to communicate with command and control servers, steal data, or redirect traffic to malicious sites. Existing security controls and perimeter defenses are not designed to prevent, isolate, and remediate DNS-based malware threats.
Firewalls are becoming increasingly important in today’s world. Hackers and automated scripts are constantly trying to invade your system and use it for Bitcoin mining, botnets or other things. To prevent these attacks, you can use a firewall on your system. IPTables is the strongest firewall in Linux because it can filter packets in the kernel before they reach the application. Using IPTables is not very easy for Linux beginners. We have created easywall - the simple IPTables web interface . The focus of the software is on easy installation and use.
