Nov 2016 Patch Tuesday: Microsoft released 14 security updates, 6 rated critical

In addition to releasing 14 security updates on Election Day Patch Tuesday, six of which are rated critical, the Microsoft Security Response Center responded to requests for better access to security update information; Microsoft’s solution was to release a preview of its new Security Update Guide, “a single destination for security vulnerability information.”MSRC added, “Instead of publishing bulletins to describe related vulnerabilities, the new portal lets our customers view and search security vulnerability information in a single online database.”To read this article in full or to leave a comment, please click here

The Internet is Hostile: Building a More Resilient Network

In a recent post we discussed how we have been adding resilience to our network.

The strength of the Internet is its ability to interconnect all sorts of networks — big data centers, e-commerce websites at small hosting companies, Internet Service Providers (ISP), and Content Delivery Networks (CDN) — just to name a few. These networks are either interconnected with each other directly using a dedicated physical fiber cable, through a common interconnection platform called an Internet Exchange (IXP), or they can even talk to each other by simply being on the Internet connected through intermediaries called transit providers.

The Internet is like the network of roads across a country and navigating roads means answering questions like “How do I get from Atlanta to Boise?” The Internet equivalent of that question is asking how to reach one network from another. For example, as you are reading this on the Cloudflare blog, your web browser is connected to your ISP and packets from your computer found their way across the Internet to Cloudflare’s blog server.

Figuring out the route between networks is accomplished through a protocol designed 25 years ago (on two napkins) called BGP.

BGP allows interconnections between Continue reading

Reaction: Issue a press release

Ladies and gentlemen, start your crystal balls—it is close to the end of the year, that favorite time of prognosticators and analysts everywhere to tell us what is going to be “hot” and “not” next year. But before you drop out of a good conversation with your family, or sitting around the dinner table eating one more piece of pie, let me ask—have you ever checked on last year’s predictions?

Here is a favorite of mine: “Books will soon be obsolete in schools.” So up to the minute, right? So in touch with the reality of today. Only it’s not. This is Thomas Edison in 1913. While I wasn’t alive back then to read the papers, I can assure you I’ve heard many other folks make the same prediction in the intervening years. The way these sorts of predictions normally work is this:

  • Choose a technology that seems directly related to an existing way of doing things. The current way of doing things, or the current technology, needs to be widespread, recognizable, and somehow seen as “fundamental.” In the modern networking world, routers would be an equivalent.
  • Choose a date that is just far enough ahead to seem Continue reading

How to crack the coding challenge

Even for the most seasoned software engineer or developer with a background education in computer science or engineering, completing a coding challenge or a technical screening can be nerve-wracking. Now, imagine you’re a self-taught developer -- the anxiety levels skyrocket.But formal education in computer science, software programming and/or engineering is not mandatory, and in the current IT talent war, the need for those credentials is diminishing further. Many self-taught coders are just as competent as those with a formal degree. The trick is getting past the unconscious biases levied against those without a degree.“From talking to self-taught programmers, I’ve found that one of their biggest sources of fear is the knowledge that they don’t have a degree. Non-traditional candidates are really intimidated by technical screenings, coding interviews, because they’ve been made to feel they’re not qualified without that computer science degree. But I don’t feel that’s true,” says Gayle Laakmann McDowell, founder of technical career consulting firm CareerCup and author of Cracking the Coding Interview.To read this article in full or to leave a comment, please click here

Carnegie Mellon researchers visualize way to fend off DDoS attacks

Following the massive DDoS attack that last month that targeted DNS provider Dyn and temporarily knocked Twitter, Netflix and other big names off the Internet, we were bombarded with pitches from vendors begging to offer their expert opinions on the matter while extolling the virtues of their solutions that naturally would have safeguarded organizations.Now, a couple of weeks later, Carnegie Mellon's CyLab Security and Privacy Institute too is touting research that it says shows that the tools really needed to stymie such attacks are on the way. Somehow, this seems more believable than some of the all-to-eager vendor claims, though it doesn't appear the tools will quite be ready to fly for imminent DDoS attack candidates, such as 2016 U.S. Presidential Election-related sites and Black Friday 2016 websites.To read this article in full or to leave a comment, please click here

Worth Reading: Blocking DDoS at Domain Registration

PREDATOR which stands for ‘Proactive Recognition and Elimination of Domain Abuse at Time-Of-Registration,’ is based on the notion that criminals need to obtain many domains to ensure profitability and attack agility, leading to abnormal registration behaviors such as burst registrations and textually similar names. “The intuition has always been that the way that malicious actors use online resources somehow differs fundamentally from the way legitimate actors use them,” says Princeton University computer science professor Nick Feamster — one of the researchers who worked on the project. “We were looking for those signals: what is it about a domain name that makes it automatically identifiable as a bad domain name?” —CircleID
