Everything BitShield News has reported about dns security: 4 stories, newest first. Part of our Threat Intelligence coverage.
Standard firewalls often miss DNS tunneling because the traffic looks like legitimate name resolution requests, allowing data to leak through port 53 without triggering alerts.
Attackers bypass firewalls by encoding malicious data inside standard Domain Name System queries, turning routine lookups into covert communication channels.
Fast flux networks hide malware behind rotating IP addresses, making traditional host-based detection ineffective until lateral movement occurs.
Blocking recursive queries at your network edge removes the primary vector attackers use to magnify traffic volume against your systems.
