Wi-Fl blocking issue prompts convention industry to band together

Operators of convention centers and other public assembly venues are joining forces to avoid becoming the next Marriott or Hilton in the eyes of an FCC Enforcement Bureau that’s been cracking down on Wi-Fi blockers.Wi-Fi blocking has become a hot button issue across the hospitality and convention center industry, as well as across the wireless LAN industry, in light of big FCC fines against outfits found to have been blocking use of wireless hotspots by those who have a legal right to access unlicensed spectrum.MORE: Wi-Fi blocking debate far from overTo read this article in full or to leave a comment, please click here

IDG Contributor Network: Building malware defenses: Control email, web browsers, and ports

Our last article looked at applying Critical Security Controls 4, 5, and 6 to your organization, covering vulnerability assessment, administrative privileges, and audit logs. Now it’s time to move on to CSCs 7, 8, and 9.Email programs and web browsers are still the most common points of entry for attackers, too many companies have woefully inadequate malware defenses, and a failure to control ports and limit services is like leaving a window open for cybercriminals.Critical Control 7: Email and Web Browser Protections Human behavior is still the path of least resistance for cybercriminals, and they often employ social engineering techniques to gain access to systems. Despite the rising profile of phishing, 23% of recipients open phishing messages and 11% click on attachments, according to Verizon’s 2015 Data Breach Investigations Report (DBIR).To read this article in full or to leave a comment, please click here

Microsoft move to revoke trust in 20 root certificates could wreak havoc on sites

Tens of thousands of secure websites might start to display certificate errors to their visitors in January, when Microsoft plans to stop trusting 20 certificate authorities (CAs) from around the world.The list of certificates that are scheduled to be removed from Microsoft's Trusted Root Certificate Program belong to CAs run by private or state-owned organizations from the U.S., France, the Czech Republic, Japan, Denmark, Chile, Turkey, Luxembourg, Ireland, Slovenia and Brazil.With their removal from Microsoft's program, the CAs will also be removed from the certificate trust list in Windows that's used by browsers such as Google Chrome, Internet Explorer and Microsoft Edge, as well as by email clients and other applications that support secure communications over SSL/TLS.To read this article in full or to leave a comment, please click here

Business Titles: CEO, Founder, Managing Director, Proprietor

Twitter is a great place to air thoughts, gather thoughts, create allies and destroy bridges. Twitter is also limited to 140 characters. Not great for talking about complex things. For large subject areas, Tweets are normally pre-appended with [x/y], which designates what message out of the chain this particular one is. Tweeting about emotional and sensitive things is probably something I need to stop doing, especially without the means to portray the exact meaning behind the Tweets and feeling that goes with it.

To those that have recently started those businesses, you have my respect for jumping in with both feet, not to be confused with gripes about titles!

Being Misunderstood and Business Titles

With startups being the ‘in thing’ and the millennials starting ‘micro businesses’, the misuse of titles grinds on me for very valid reasons. Everyone wants to be that person that sells their startup for millions, or gets recognition on TED for being awesome. I have news. Most companies fail within the first year or two. Most never make it past five years. Those that do in most cases have gambled everything to win. As newer technologies sees new roles and skill sets being developed, it’s only Continue reading

Should you buy cyber insurance?  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  Cyber insurance is rapidly becoming an important part of many organizations' risk mitigation strategy. While most businesses have some sort of property or general liability insurance, those policies exclude coverage for cyber liability, so cyber insurance has become its own category, and it's the fastest growing area of insurance for businesses. At least 50 major providers now offer this type of insurance, attracted by the fact that demand for cyber insurance has been rising by double digit percentages for the last few years.To read this article in full or to leave a comment, please click here

Apple CEO defends privacy, encryption amidst terrorist concerns

Apple CEO Tim Cook staunchly defended personal privacy and the use of encryption on iPhones amidst renewed concerns about terrorists hiding covert electronic messages when they plan deadly attacks.In an interview with Charlie Rose on CBS This Morning that aired Friday, Cook said the supposed tradeoff between privacy and security is "only a simplistic view—we can have both."Cook repeated Apple's stance that it complies specifically with court-ordered warrants to produce information as required by law enforcement, but said of encrypted data on iPhones, "We don't have it to give." That's because Apple's iPhones running versions after iOS 4 keep decryption keys on a user's iPhone and not on a server or some other place, as Apple has pointed out many times before.To read this article in full or to leave a comment, please click here

Unser neues 72. Rechenzentrum: Hamburg

Moin Hamburg! Ensconced alongside the Elbe River, Hamburg, a major port city in northern Germany, is the second largest city in the country, and the eight largest in the European Union. Our data center in Hamburg is our 4th in Germany following deployments in Frankfurt, Düsseldorf and Berlin, our 19th in Europe, and 72nd globally. This means not only better performance in Germany, but additional redundancy for our 3 other data centers throughout the country. As of this moment, CloudFlare has a point of presence (PoP) in 8 out of Europe's 10 most populous* cities, and we're headed for a perfect 10-for-10 (look out Budapest...).

For the local audience: Liebe Freunde in Hamburg, Euer Internetanschluss ist schneller geworden und ihr könnt jetzt sicherer surfen. Viel Spaß.

Frohe Festtage!

Be sure to have some Glühwein if you visit the Christkindlmärkte this holiday season

Yesterday we announced new points of presence (PoPs) in Montreal and Vancouver. Today: Hamburg. However, the holidays are hardly over, and we have lots more cheer to spread. We've sent planes sleighs full of servers, switches, routers and PDUs to many corners of the globe. And to cap it off, we'll gift some CloudFlare gear Continue reading

Worth Reading: What we should fear in the world of patents

…only rarely are those accused of some patent violation really a bad actor. Rather, the patent system results in bad actors because the system is confusing with little transparency. When patents are unclear, in other words when the boundaries of a patent are vague, then people cannot adequately check whether their innovations infringe. If they have no reliable means of checking then innovators will find it hard, likely impossible, to design around a patent, or even to seek an appropriate patent license. via heartland

BGP RIB Failure

An infrequent, yet interesting issue that comes up occasionally is when BGP encounters RIB failures. Usually, it takes the form of a prefix which you’d expect a router to learn via eBGP in its RIB being learnt via a routing protocol with a worse administrative distance.

To understand this problem, we first need to realise that “RIB failure” in a “show ip bgp” output implies that a route offered to the RIB by BGP has not been accepted. This is not a cause for concern if you have a static, or connected route to to that network on the router, but if you’re expecting it to be via eBGP then you can infer that something is misconfigured with your routing.

This can also be simplified to “BGP does not care about administrative distance when selecting a path”.

For reference, the path selection algorithm goes:

Network layer reachability information.

Weight (Cisco proprietary). Bigger is better.

Local preference

Locally originated route

AS path length

Origin code. IGP>EGP>Incomplete

Median Exit Discriminator. Lower is better.

Neighbour type. eBGP better than iBGP.

IGP metric to Next Hop. Lowest Router ID wins.


OSFP Forwarding Address Part I: Type 5 LSA Suppression

OSPF (Open Shortest Path First) is mostly seen as a pretty nasty routing protocol, with a load of subtleties and corner cases. I’ve decided to talk about a subject which usually gives a lot of troubles to most network professionals – the Forwarding Address (FA).

So, we’re going to clear things on why does OSPF set or doesn’t set the FA, what is it used for, how is the best path selection is influenced by the setting of the FA and we’ll also see some examples that may throw some light on this subject. But first, let’s clarify what the forward address is. As per the RFC, the forward address is defined as:

Forwarding address
        Data traffic for the advertised destination will be forwarded to
        this address.  If the Forwarding address is set to 0.0.0.0, data
        traffic will be forwarded instead to the LSA's originator (i.e.,
        the responsible AS boundary router).

Probably the most important thing when you start the deep dive into this subject is having the right topology to work with, which allows you to see the less usual cases regarding how redistribution into OSPF works.

Considering the network topology below, I have Continue reading
