Ethical Hacking: Turning The Tables to Boost Cyber Security

Hacking remains a huge problem for businesses. As noted by MarketWatch, more than 175 data breaches have already happened this year, and in 2015 approximately 105 million adults in the United States had their personal information stolen. For companies, the stakes are huge: Compromised systems not only damage the bottom line but can severely impact public opinion. more

Unlimited Bandwidth is Disrupting Infrastructure Models

Over the last ten years we have heard a lot about edge-based services. These were needed to enable the operation of applications at the edge of the network, as the lack of available bandwidth capacity made it difficult to do so over the core network. However, with the prospect of limitless bandwidth the design of the network is changing again. more

Decision Time for the Open Internet

On February 26 of this year the Federal Communications Commission (FCC) of the United States will vote on a proposed new ruling on the issue of "Network Neutrality" in the United States, bringing into force a new round of measures that are intended to prevent certain access providers from deliberately differentiating service responses on the carriage services that they provide. more

BGP Hijacks: Two More Papers Consider the Problem

The security of the global Default Free Zone (DFZ) has been a topic of much debate and concern for the last twenty years (or more). Two recent papers have brought this issue to the surface once again - it is worth looking at what these two papers add to the mix of what is known, and what solutions might be available. The first of these traces the impact of Chinese "state actor" effects on BGP routing in recent years. more

Security and Reliability: A Closer Look at Vulnerability Assessments

Building on my last article about Network Assessments, let's take a closer look at vulnerability assessments. (Because entire books have been written on conducting vulnerability assessments, this article is only a high level overview.) What is a vulnerability assessment? more

Government-Industry Collaboration Is Better than Developing a Surveillance State

President Obama, in March 2016, again stressed the need for better collaboration between the tech industry and the government. He referred to his own White House initiative - this has resulted in the newly-formed US Digital Service, which is trying to recruit the tech industry to work with and for government. One of the key reasons it is so difficult to establish trustworthy, good working relationships is the extreme lack of tech understanding among most politicians and government bureaucrats. more

The Cyberthreats and Trends Enterprises Should Watch in 2016

Every year, Verisign iDefense Security Intelligence Services produces its Cyberthreats and Trends Report, which provides an overview of the key cybersecurity trends of the previous year and insight into how Verisign believes those trends will evolve. This report is designed to assist in informing cybersecurity and business operations teams of the critical cyberthreats and trends impacting their enterprises, helping them to anticipate key developments and more effectively triage attacks and allocate their limited resources. more

CE Router Certification Opens Up the Last Mile to IPv6 Fixed-Line

With reference to IPv6, probably most end users do not have any sense of it. The mainstream condition in the industry is that network carriers and content/service providers stick to their own arguments. Carriers consider lack of IPv6 content and service as the reason demand for IPv6 from the users is very low. The content and service providers believe that users cannot have access to content and service through IPv6 and thus carriers should provide the service in the background. more

Mega Hacks and the Employees That Lost

When a business gets hacked and its corporate information is dumped on the Internet for all and sundry to see (albeit illegally), the effects of that breach are obviously devastating for all concerned. In many ways it's like the day after a fierce storm has driven a super-cargo container ship aground and beachcombers from far and wide have descended upon the ruptured carcass of metal to cart away anything they think has value or can be sold by the side of road. more

Hot Architectural Issues for the Internet

The Internet Architecture Board's (IAB) chair, Olaf Kolkman, asked the members of the IAB to provide a statement paper each on what they believe the current most pressing issues in terms of Internet architecture are... I have thought about this for the past few days, and realised that it's hard to come up with overarching issues and even harder to come up with issues, where the IAB actually could make a difference. But I came with up with two issues. more

Securing the Routing System at NANOG 74

The level of interest in the general topic of routing security seems to come in waves in our community. At times it seems like the interest from network operators, researchers, security folk and vendors climbs to an intense level, while at other times the topic appears to be moribund. If the attention on this topic at NANOG 74 is anything to go by we seem to be experiencing a local peak. more

The Rise and Rise of Broadband in China

While there are plenty of articles continuously updating us on the incredible social and economic developments that are taking place in China it is still sometimes good to stand still and have a look at some of these developments. It was 15 years ago that the Chinese Government - in its 5-year plan - stated that it wanted to connect all of its half million villages to the telecommunications network. At that point the plan simply called for narrowband telephone connections. more

Life Outside IPv6 (Poll)

Within every organization a chosen few are tasked with introducing IPv6 into their networks, outward facing services or applications. But who are they? We know them as Network Engineers, System Administrators and Software Developers but are they one trick ponies spending all their time in layer 3? more

If Slate Comes in Standard Sizes, Why Not Broadband?

Last week I was at the National Slate Museum in Wales watching slate being split apart. On the wall were sample pieces of all the standard sizes. These have cute names like "princess". For each size, there were three standard qualities: the thinnest are the highest quality (at 5mm in thickness), and the thickest have the lowest quality (those of 13mm or more). Obviously, a lighter slate costs less to transport and lets you roof a wider span and with less supporting wood, hence is worth more. more

7 Reasons Why R&E Networks and Universities Are Critical to Future of Broadband

There has been considerable discussion about the future of broadband in terms of infrastructure i.e. fiber, wireless, community owned etc. However, there has been little discussion, to borrow a phrase from Internet 2, on Net+ broadband services. It is in the Net+ services where I think R&E networks can play a critical in helping communities and small commercial ISPs deploy advanced services and applications that will provide new business models to underwrite the costs of next generation broadband. more
