The DDoS myth about the firewall and the IPS

By Nirav Shah Corero | December 16, 2014 2014.12.16

It is about time we put an end to the myths that often come up when choosing a network security solution to protect against distributed denial of service (DDoS) attacks. We'll take a look at a couple of common myths, namely: Myth #1: An IPS can protect against Distributed Denial of Service (DDoS) attacks Myth #2: A...

49½ pounds of DDoS attack visibility

49½ pounds of DDoS attack visibility

By Stephen Gates Corero | October 01, 2014 2014.10.01

Why is visibility important? The answer is an easy one to deliver. When you’re under a DDoS attack or when one of your customers comes under attack, “end-point pipe” visibility is the key to quick mitigation. You cannot proactively defend a network if you cannot detect, analyze and respond to the attack and this level of visibility is critical to proper DDoS protection.
