For some time now, the cyber world has been under attack by a diffused set of enemies who improvise their own tools in many different varieties and hide them where they can do much damage. In this podcast, CERT researcher Vijay Sarvepalli explores Domain Name System or DNS Blocking, the idea of disrupting communications from malicious code such as ransomware that is used to lock up your digital assets, or data-exfiltration software that is used to steal your digital data. DNS blocking ensures a wide impact while avoiding the complexity of having to install or instrument every device in your enterprise. The key takeaway is to target a break in the chain of malware to minimize its effectiveness and the malicious code developer’s intended success.
