Better "Always-On" DDoS Mitigation

Distributed Denial of Services (DDoS) attacks have been the frustration of information technology professionals for many years. When asked, most tell you they wish their internet service providers (ISPs) would simply provide them "clean pipes" all the time and take care of DDoS attacks upstream before they ever get to them. Unfortunately, the resources (equipment and personnel) necessary to clean Internet connections all the time are very expensive and come with several downsides. more»

Domain Name System (DNS) Security Should Be One of Your Priorities

Most people, even seasoned IT professionals, don't give DNS (the Domain Name System) the attention it deserves. As TCP/IP has become the dominant networking protocol, so has the use of DNS... Due to the reliability built into the fundamental RFC-based design of DNS, most IT professionals don't spend much time worrying about it. This can be a huge mistake! more»

DDoS Attacks: Don't Be In Denial of the Risks

Unlike traditional attacks by hackers which breach a business's security systems, resulting in defaced websites, intellectual property theft and/or customer data theft, a DDoS attack focuses on making a business's Internet connected infrastructure (e.g. web servers, email servers, database servers, FTP servers, APIs, etc.) unavailable to legitimate users.

But being so prominent also means the protocol is taking shots from those who don't want to make the necessary software, hardware and operational modifications needed. And DNSSEC has taken some shots from those who just want to be contrarian. more»

Network Complexity: Three Trends That are Contributing to a "Perfect Storm"

Most everyone who visits CircleID is familiar with Moore's Law, which stated simply holds that computing power doubles every 18 months. This has been going on since the 1960s and shows no sign of slowing. Moore's Law drives faster and faster computing, which produces more and more data and network complexity. This inexorable trend is putting immense pressure on corporate networks, and the strain is too much for many of them to handle on their own. more»
