Domain name service (DNS) attacks threaten every internet connection because they can deny, intercept, and hijack connections. With the internet playing an increasing role in business, securing DNS plays a critical role in both operations and security. Everything You Need to Know.
DNS security protects the domain name system (DNS) from attackers seeking to reroute traffic to malicious sites. Since a majority of business IT traffic now accesses or passes through the internet, DNS plays an increasingly important — and vulnerable — role. in the DNS cache for more efficient delivery of information to users.
Domain name system (DNS) tunneling is a pervasive threat that enables hackers to get any data in and out of a company's internal network while bypassing most firewalls. But DNS tunneling essentially smuggles hostile traffic through DNS ports, which makes these attacks difficult to detect and mitigate.
This means they can do everything from cache responses to stop potentially malicious threats to apply firewall rules to block certain user agents or IP addresses. Onto the next piece and per the title, it's going to involve DNS rollover. As such, I need to roll DNS to go from pointing to one Function app to another one.
