DNS and Infrastracture DDoS Protection

Embed Size (px)

DESCRIPTION

DNS Protection safeguards Incapsula clients’ DNS servers, while also accelerating DNS responses. Infrastructure Protection, enabled by the addition of a GRE tunneling onboarding option, widen Incapsula's security perimeter - allowing it to protect entire subnets, secure all network elements and inspect all TCP/UDP communication.

Agenda

• Network DDoS trends

• Is a Terabit DDoS imminent?

• A DDoS resilient network

• Infrastructure and DNS protection

Where do we stand today?

59%28%

13%<20Gbps

20-40Gbps

>40Gbps

Attacks bandwidth is showing exponential growth

One third of attacks exceed 20GbpsMore than 13% exceed 40Gbps

Its not all bandwidth

More than 25% of attacks exceed 10MppsMost IPS/IDS will crash at 5Mpps

How are they reaching these numbers?

• Are botnets becoming bigger?> No, according to www.shadowserver.org

• Are there more open DNS resolvers?> No, the number is actually declining according to

www.openresolverproject.org

• Are there more open NTP servers?> Probably not

• So what is it then?

How are they reaching these numbers?

• They are using bigger guns

Example of a 4Mpps attackLess than 30 IPs are generating more than 99% of the traffic

What can we learn from all this?

• The stronger the internet is becoming, the stronger the attacks

• The largest attacks use a small set of super resources rather than a large set of weak resources

• Attacks will far exceed a single network capacity

• Should we expect a 1Tbps+ attack within the next 12-36 months?

A DDoS resilient network

• Can scale its capacity on demand> Cloud solution are built to scale efficiently> Cloud provides the most cost effective way to scale capacity

• Can protect any service from any attack> Both layer 3&4 and layer 7 mitigation is required> Web servers and DNS servers are a target for sophisticated attacks

• Provides real time visibility> You cannot mitigate what you cannot see

• Can respond rapidly to changes> DDoS mitigation is a delicate balance between false positives and

false negatives> You need to react quickly to any change that disrupts this balance

The “Behemoth”

• We still need to filter DDoS traffic…

• Our requirements> Filter 100Gbps+ of traffic per POP> Manage BGP for announcing > Manage GRE for origin forwarding> Software defined network (SDN) capabilities

• The solution> An appliance that can deal with 170Gbps> Advanced implementations of DDoS filtering algorithms> Anomaly detection> Proprietary implementation of BGP and GRE> C&C for internal networking devices
