Dr. Q, you have an incoming video call.
Robbie, clear the lines, I am expecting a call from an IT Director who has been experiencing
DNS denial of service attacks!
Sir, you have a video call
Oh, it’s you. You’re calling about the D-O-S attacks. F5 can help.
Here’s the problem. When users request your web page the request accesses local DNS
servers, and these in turn communicate with your main DNS servers.
Normal loads are no problem for your main DNS servers.
Until … an attacker targets your DNS server with a flood of DNS requests, which ultimately
brings down your main DNS server.
You see, the capacity of your best DNS server is probably about 150,000 queries per second
and the bad guys are exceeding that.
To protect against this threat, many companies add additional DNS servers. These are unnecessary
for normal day-to-day activities, and an expansive solution, but when the hackers try again,
the beefed-up DNS server farm is able to withstand the attack.
There is a better way: F5’s DNS Express.
Instead of purchasing additional DNS servers that are not needed for everyday operations,
add a F5 BIG-IP GTM in front of your main DNS server.
DNS Express handles requests on behalf of the Main DNS server. DNS Express works at
high speed from RAM. It can handle more than 2 million requests per second, an increase
of 12 times. More than enough to withstand a DNS denial of service attack.
So, while these types of attacks are on the rise, with F5 you can easily protect yourself.
“Well done, old boy!”
F5. IT Agility. Your way.
