Myanmar Internet Down from Massive DDoS Attack

Craig Labovitz of Arbor Networks reports: "Back in 2007, the Myanmar government reportedly severed all Myanmar Internet connectivity in a crackdown over growing political unrest. Yesterday, Myanmar once again fell of the Internet. Over the course of the past several days, Myanmar's main Internet provider, the Ministry of Post and Telecommunication (or PTT for short), suffered a large, sustained DDoS attack disrupting most network traffic in and out of the country." more

Malware Increasingly Uses DNS As Command and Control Channel to Avoid Detection

Number of malware threats that receive instructions from attackers through DNS is expected to increase, and most companies are not currently scanning for such activity on their networks, security experts said at the RSA Conference 2012 on Tuesday. While most malware-generated traffic passing through most channels used for communicating with botnets (such as TCP, IRC, HTTP or Twitter feeds and Facebook walls) can be detected and blocked, it's not the case for DNS (Domain Name System) and attackers are taking advantage of that, said Ed Skoudis, founder of Counter Hack Challenges and SANS fellow. more

A Glance Back at the Looking Glass: Will IP Really Take Over the World?

In 2003, the world of network engineering was far different than it is today. For instance, EIGRP was still being implemented on the basis of its ability to support multi-protocol routing. SONET, and other optical technologies were just starting to come into their own, and all-optical switching was just beginning to be considered for large-scale deployment. What Hartley says of history holds true when looking back at what seems to be a former age: "The past is a foreign country; they do things differently there." more

Landmark IPv6 Report Published: State of Deployment 2017

On the fifth anniversary of World IPv6 Launch, we're excited to share a detailed report on the State of IPv6 Deployment in 2017. It really is staggering how far IPv6 deployment has progressed in five years. In mid-2012, Google measured less than 1% of users accessing their services over IPv6. Today that figure is getting close to 20%. Since World IPv6 Launch, several major operators are now delivering the majority of traffic from major content sources like Google, Akamai and others over IPv6. more

Dissecting the (Likely) Forthcoming Repeal of the FCC’s Privacy Rulemaking

Last week, the House and Senate both passed a joint resolution that prevent's the new privacy rules from the Federal Communications Commission (FCC) from taking effect; the rules were released by the FCC last November, and would have bound Internet Service Providers (ISPs) in the United States to a set of practices concerning the collection and sharing of data about consumers. The rules were widely heralded by consumer advocates, and several researchers in the computer science community, including myself, played a role in helping to shape aspects of the rules. more

2023 Routing Security Summit Starts July 17 - Participate Virtually

Interested in learning more about routing security? How it can affect your connectivity supply chain? What are best practices for enterprises and organizations? What is the role of CSIRTs in securing routing? What are governments doing now, and planning to do in the future around routing security? more

Which Way Does Your Data Flow?

Data may be moving to the cloud, but understanding the physical geography underlying the cloud is becoming increasingly critical. October's decision by the European Court of Justice, striking down key portions of the Safe Harbor rules that some companies had relied on to legally transfer personal data between Europe and the U.S., was only the latest example of the regulatory uncertainty involved in cross-border data flows. While Internet companies have begun to address challenges at the static geographic points where data is resident, understanding the actual paths that data travels is an important and sometimes overlooked part of the compliance analysis. more

Data, Applications, and the Meaning of the Network

Two things seem to be universally true in the network engineering space right this moment. The first is that network engineers are convinced their jobs will not exist, or there will only be network engineers "in the cloud" within the next five years. The second is a mad scramble to figure out how to add value to the business through the network. These two movements are, of course, mutually exclusive visions of the future. more

Trump Signs Cybersecurity Executive Order, Experts Weigh in on the New Draft

The long-waited cybersecurity executive order expected to launch sweeping reviews of the federal government's digital vulnerabilities, was signed today by President Trump. more

Vodafone Plans to Create the First 4G Network on the Moon, Appoints Nokia as Technology Partner

Vodafone is working on a project to create the first 4G network on the Moon to support a mission by PTScientists in 2019. Nokia is chosen as the company's technology partner, according to a press release issued today. more

Good Samaritans with Network Visibility

In a big open office 30 feet from me, a team of US Veterans speak intently on the phone to businesses large and small, issuing urgent warnings of specific cyber security threats. They call to get stubborn, confused people to take down hidden ransomware distribution sites. They call with bad news that a specific computer at the business has malware that steals login credentials. more

LinkedIn Outage Due to DNS Issue

Users of LinkedIn were unable to access the site for several hours due to what the company has reported to have been a DNS issue. The site is claimed to have been accidentally pointed to a domain name parking page and some users were greeted with a domain for sale page when trying to access LinkedIn's homepage. According to downrightnow, LinkedIn's outage began around 6 pm PST on Wednesday and is continuing, though website has gradually resumed for some users. more

Substantial Majority of Americans Say Local Governments Should Be Able to Build Their Own Broadband

A recent study conducted Pew Research Center in March 13-27, has found a substantial majority of the American public (70%) believes local governments should be able to build their own broadband networks if existing services in the area are either too expensive or not good enough. more

IP Address Location Data

The last few years have shown us how the Internet shrinks distances between distributed teams, organizations and families. This poses a challenge for some organizations. Many business relationships and contractual agreements involving the Internet have geographical implications and restrictions. This matters to anyone operating a network. It is most important for networks that get new address space. more

Networks Are Not Cars Nor Cell Phones

The network engineering world has long emphasized the longevity of the hardware we buy; I have sat through many vendor presentations where the salesman says "this feature set makes our product future proof! ... Over at the Networking Nerd, Tom has an article posted supporting this view of networking equipment, entitled Network Longevity: Think Car, not iPhone. It seems, to me, that these concepts of longevity have the entire situation precisely backward. more
