DDoS Attack

New Threats Demand a New Approach to DDoS Protection

In the past 24 months, distributed denial of service (DDoS) attacks have changed profoundly. Gone are the days when attackers worked under the radar, when machines were infected by botnet code unknowingly and attacks were disguised leaving very little to trace the exact origin. ... The other game-changer: It's easier than ever to execute attacks. The tools are so widely available that anyone with basic skills and a high-speed connection can become a "hacktivist."

DDoS Attacks: What’s in Store for 2012?

According to Kaspersky Lab, 2011 has seen "numerous DDoS attacks with a variety of motives," many of which will "go down in the annals of cybercrime." As we look ahead to 2012, it's worth examining some of those motives to see what they portend.

Neustar Professional Services: Additional Expertise to Improve Productivity

While it would be nice if your company had IT staff members that were experts in every technology, that is just not realistic. And today, many companies face the challenge of finding the appropriate and specialized expertise that is required to deal with ongoing issues such as network optimization, performance degradations, network risks, and more.

The Human Factor in DDoS Attacks

Ripped from the headlines: A recent DDoS attack lasted an entire 60 days. In other news, a single site was attacked 218 times in Q2 alone. To those of us in the business of protecting Web infrastructure, these stories are hardly surprising. What's notable, though, is where they were reported, in The Financial, whose focus is banking and financial services, not technology. The reporters used the term "DDoS" as if it were as common as "hedge fund," something everyday business people, not just techies, grasp. It's this human element that caught my interest and got me thinking a little.

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. A business's brand reputation, which can take years to establish, can be swept away in just a few hours from a single DDoS attack in the same way a natural disaster like a flood or earthquake can impact a traditional brick and mortar business.

8 Security Considerations for IPv6 Deployment

Feb. 3, 2011, came and went without much fanfare, but it was a milestone for Internet stakeholders, whether they knew it or not. On that Thursday, the last available IPv4 addresses were allocated by the Internet Assigned Numbers Authority (IANA). Though some Regional Internet Registries (RIRs) have a reasonable inventory of IP addresses that could last another year or two, the days of "new" IPv4 address allocations are largely over.

Understanding the Modern DDoS Threat

The breadth of cyber threats that an organization must engage with and combat seemingly change on a daily basis. Each new technology, vulnerability or exploit vector results in a new threat that must be protected against. Meanwhile some forms of attack never appear to age -- they remain a threat to business continuity despite years of advances in defensive strategy. One particularly insidious and never-ending threat is that of the Distributed Denial of Service (DDoS) attack.

Responsibilities of the DNS: “Oh YES you will!”, “Oh NO you will not!”

What is the responsibility of the DNS? Should the DNS be responsible for policing traffic across its infrastructure? Should the blocking and blacklisting of names or throttling of query packets be the responsibility of the DNS? From experience I know my opening paragraph has started passionate debates in more than one section of this globe. We at CommunityDNS have found ourselves right in the middle of such heated debates. "Oh YES you will!", "Oh NO you will not!"

The Dark Internet

I consult on communication issues for Neustar, an Internet infrastructure company. As most CircleIDers know, Neustar works behind the scenes to ensure the smooth operation of many critical systems like DNS, .us and .biz, local number portability and digital rights management. One of the cool things about working for them is the chance to attend the events they sponsor. Last week Neustar held a security briefing for senior federal IT personnel focused on Cybersecurity and Domain Name System Security Extensions (DNSSEC)...

Wikileaks DDoS of Spamhaus: Political Activism at Its Dumbest

A week ago, Paul Vixie wrote a thoughtful piece on the morality of DDos, for both sides of the equation of the Wikileaks issues. In it he summarizes things nicely: "Denial of service is not merely a peaceful protest meant to garner attention for a cause. Denial of service is forcible and it is injurious. It is not like any form of civil disobedience, but rather it is criminal behaviour more like looting." Well said, Paul...
