New CEO Stresses ICANN’s Role in Cybersecurity

One summer sport in Internet governance is speculating on what direction ICANN's new CEO will take it in. Making the media rounds yesterday on Fox and Lehrer News Hour to talk about the recent DDoS attacks on US and S. Korea government and commercial websites, new CEO Rod Beckstrom pushed how the response to cyber attacks is a coordinated effort, he also alluded to ICANN's role in similar attacks. Responding to a question on the News Hour about the USG policy response to dealing with cyber attacks, Beckstrom highlighted the critical role of ISP filtering, and identified the "organic" as well as "somewhat structured" coordination which occurs during a typical response. More interestingly, he plugged ICANN's facilitating role. more

DNS: The Basis for Billions

In the midst of "Cyber Monday", the day traditionally seen as one of the year's busiest days for online shopping, it is only appropriate to examine the importance DNS plays for online economies.

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. more

Recommendations for Adding Cybersecurity Intelligence to the Smart Grid

Over the last few years, there has been an increased effort to modernize the U.S. electric grid. Building a "Smart Grid" has been central in the effort to help utilities better manage their resources, minimize power outages and reduce energy consumption. However, adding more electronic devices and sensors to the grid's network has made it a prime target of cyberattacks, like Distributed Denial of Service (DDoS) attacks, which if successful, could cause wide-spread disruption of services affecting many other sectors. more

Iranian Protesters Urged Not to DDoS Gov Sites, Could Backfire as Country’s Networks Are Centralized

In the midst of heavy demonstrations in the street of Iran against current regime and controversial election results, online activist have began organizing online attacks against government websites. Activists are asking supporters to use tools currently being spread via Twitter, Facebook, and other social networking sites to participate in the attack. However as one blogger writes, the attack might in fact back fire in a country like Iran where network infrastructure is relatively centralized... more

Understanding the Threat Landscape: Basic Methodologies for Tracking Attack Campaigns

The indicators of compromise (IOCs) outlined in my last blog post can be used as a baseline for developing intrusion sets and tracking attack campaigns and threat actors. When launching an attack, threat actors use a variety of vectors and infrastructure, which Verisign iDefense analysts -- as well as analysts across the cybersecurity community -- correlate to group attacks, tracking actors and determining attack methods. more

Cloud Computing’s Concealed Complexity

James Urquhart claims Cloud is complex - deal with it, adding that "If you are looking to cloud computing to simplify your IT environment, I'm afraid I have bad news for you" and citing his earlier CNET post drawing analogies to a recent flash crash. Cloud computing systems are complex, in the same way that nuclear power stations are complex - they also have catastrophic failure modes... more

A Logical Place to Start the IPv6 Transition

The transition to IPv6 is top of mind for most service providers. Even in places where there are still IPv4 addresses to be had surveys we've run suggest v6 is solidly on the priority list. That's not to say everyone has the same strategy. Depending where you are in the world transition options are different -- in places such as APAC where exhaustion is at hand one of the many NAT alternatives will likely be deployed since getting a significant allocation of addresses is not going to happen and other alternatives for obtaining addresses will prove expensive. more

Breaking Down Silos Doesn’t Come Easy

"We need to break down silos", is a phrase often heard in national and international meetings around cyber security and enforcing cyber crime. So it is no coincidence that at the upcoming NLIGF (Netherlands Internet Governance Forum), the IGF, but also an EU driven event like ICT 2013 have "Breaking down silos" and "Building bridges" on the agenda. But what does it mean? And how to do so? more

Identify DDoS Attacks with Monitoring of Internal Applications (Part 1 of 3)

Most cloud DDoS mitigation services are offered on demand meaning that customers can enable the service when they are the victim of a DDoS attack. But how can a company find out -- quickly -- that it is under attack? Sometimes it is difficult to know. In this three part series, we will examine multiple monitoring tools companies can use to capture DDoS, which can help determine whether you are under a DDoS attack. more
