How To Prepare For A DDoS Attack: 10 Steps

Like a hurricane or a flood, a DDoS is a crisis. Follow these 10 steps to prepare for an attack before it hits.

Distributed denial of service (DDoS) attacks are scary. In a matter of minutes, they can shut down a network, service or website, costing companies millions of dollars.

A recent study by Corero Network Security found that while 34 percent of IT managers surveyed cited lost revenues as the most damaging consequence of a DDoS. Nearly half -- or 45 percent -- say loss of customer trust and confidence is their greatest concern.

When they first came on the scene 20 years ago, a DDoS -- which is when a large network of botnets overwhelm another system’s connection causing it to deny service to legitimate traffic – even threatened to take down the Internet itself.

That’s ancient history. Over time, vendors and service providers have developed products that help IT staffs better cope with the threat of a DDoS. But they come in waves and over the past year there has been an uptick in DDoS attacks.

“There have always been various waves of DDoS attacks, and we saw one toward the end of 2015,” says Barry Greene, CTO of Palo Alto-based GetIT, or Green Energy Technology & Infocommunications Technology.

Greene says that although we are currently experiencing a bit of a lull, now’s a good time to prepare for the next wave. He recently authored a white paper on preparing for a DDoS and spent some time talking with Dark Reading about strategies for defending against DDoS attacks. 

“Think of a DDoS as a crisis much like a hurricane or a flood,” Greene says. “You wouldn’t want to start preparing for a hurricane on the day of the event. The same holds true for a DDoS.”

CVE-2020-25596
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. x86 PV guest kernels can experience denial of service via SYSENTER. The SYSENTER instruction leaves various state sanitization activities to software. One of Xen's sanitization paths injects a #GP fault, and incorrectly delivers it twice to the guest. T...
CVE-2020-25597
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. There is mishandling of the constraint that once-valid event channels may not turn invalid. Logic in the handling of event channel operations in Xen assumes that an event channel, once valid, will not become invalid over the life time of a guest. Howeve...
CVE-2020-25598
PUBLISHED: 2020-09-23
An issue was discovered in Xen 4.14.x. There is a missing unlock in the XENMEM_acquire_resource error path. The RCU (Read, Copy, Update) mechanism is a synchronisation primitive. A buggy error path in the XENMEM_acquire_resource exits without releasing an RCU reference, which is conceptually similar...
CVE-2020-25599
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. There are evtchn_reset() race conditions. Uses of EVTCHNOP_reset (potentially by a guest on itself) or XEN_DOMCTL_soft_reset (by itself covered by XSA-77) can lead to the violation of various internal assumptions. This may lead to out of bounds memory a...
CVE-2020-25600
PUBLISHED: 2020-09-23
An issue was discovered in Xen through 4.14.x. Out of bounds event channels are available to 32-bit x86 domains. The so called 2-level event channel model imposes different limits on the number of usable event channels for 32-bit x86 domains vs 64-bit or Arm (either bitness) ones. 32-bit x86 domains...
