911 emergency services ripped by HBO’s John Oliver

It’s definitely a service that’s taken for granted but HBO’s John Oliver this week pointed out that there’s a lot to be concerned about over the nation’s 911 emergency service.On Oliver’s Last Week Tonight HBO show, Oliver said 911 emergency call centers are antiquated, disjointed and in desperate need of funding and new technology. He said everyone should Google “understaffed 911 dispatch and [your town name]” to get an idea of problems near you and nationwide.Watch: The watchdogs at the Government Accountability Office in 2013 wrote about 911 technologies: “The continuing evolution of communications technologies and wireless phones has implications for 911 services. Since 911 call centers predominantly use older, analog-based infrastructure and equipment, the current E911 system is not designed to accommodate emergency communications from the range of new technologies in common use today, including text and picture messaging and Voice-over-Internet Protocol (VoIP) telephony (e.g., Skype). In response to changing technologies, the Department of Transportation (DOT) launched the Next Generation 911 (NG911) Initiative, which has focused on the research required to develop an NG911 system. With NG911 services, the public could reach 911 call centers through various modes, including voice and data, and transmit multimedia Continue reading

A critical flaw in Symantec antivirus engine puts computers at risk of easy hacking

The antivirus engine used in multiple Symantec products has an easy-to-exploit vulnerability that could allow hackers to easily compromise computers. The flaw was fixed by Symantec in Anti-Virus Engine (AVE) version 20151.1.1.4,  released Monday via LiveUpdate. The flaw consists of a buffer overflow condition that could be triggered when parsing executable files with malformed headers. According to Google security engineer Tavis Ormandy, who found the flaw, the vulnerability can be exploited remotely to execute malicious code on computers. All it takes is for the attacker to send an email with the exploit file as attachment or to convince the user to visit a malicious link.To read this article in full or to leave a comment, please click here

9 business-worthy Chrome for Work devices

Chrome for Work devicesChromebooks have been around for a while, but they haven't received nearly as much business press as hybrid devices like the Surface Pro 4 or iPad Pro. But while they may be flying under the radar, Google has an entire lineup of Chrome-based devices aimed at business users. While these devices might not get as much enterprise-worthy buzz, they are well-equipped for both casual and power users alike. They run the gamut in terms of design and configuration, which means there is likely an option for you -- whether you want a desktop, tablet or notebook experience. Here are nine Chrome for Work devices you've probably never heard of aimed at the enterprise.Acer ChromebaseThe Acer Chromebase will remind you of those all-in-ones that were slated to be the future of the desktop just a few years ago. It features a 21.5-inch touchscreen display, 4 GB of memory, a 16GB hard drive and an NVIDIA Tegra K1 processor.

Cybercriminal business model vulnerable to intervention

Cybercrime may be booming but its business model is vulnerable on many fronts, according to a new report."We've been observing that they've been acting like a business for a while," said Shogo Cottrell, security strategist at Hewlett Packard Enterprise, which produced the report.The profit motivation accounts for more than three-quarters of all data breaches and has been rising in recent years, according to this year's Verizon data breach report.But cybercrime also shares many of the vulnerabilities that traditional businesses do, said Cottrell.MORE ON CSO: How to spot a phishing email For example, a criminal group's reputation is even more important in the underground economy than brand reputation in the legitimate world.To read this article in full or to leave a comment, please click here

How 5 IT leaders beat their toughest technical challenges

People who lead large IT organizations don’t have much time to deal with the nitty-gritty technical details of how their systems run. Their priorities are to provide strategic technology leadership, set policies and manage the overall operation. CIOs and other IT leaders also have to work with executives in other departments to make sure IT is providing the services the business needs. But there are times when a technical problem crops up that requires the boss’s attention, and on those occasions finding the right solution can seem like an overwhelming challenge.To get a sense of the type of technical issues CIOs have to deal with, we asked five IT leaders to recall vexing problems they were able to solve without resorting to complicated, high-cost rollouts.To read this article in full or to leave a comment, please click here

The Sleepy User Agent

From time to time a customer writes in and asks about certain requests that have been blocked by the CloudFlare WAF. Recently, a customer couldn’t understand why it appeared that some simple GET requests for their homepage were listed as blocked in WAF analytics.

A sample request looked liked this:

GET / HTTP/1.1
Host: www.example.com
Connection: keep-alive
Accept: text/html,application/xhtml+xml,application/xml;q=0.9,image/webp,*/*;q=0.8
Upgrade-Insecure-Requests: 1
User-Agent: Mozilla/5.0 (compatible; MSIE 11.0; Windows NT 6.1; Win64; x64; Trident/5.0)'+(select*from(select(sleep(20)))a)+' 
Accept-Encoding: gzip, deflate, sdch
Accept-Language: en-US,en;q=0.8,fr;q=0.6

As I said, a simple request for the homepage of the web site, which at first glance doesn’t look suspicious at all. Unless your take a look at the User-Agent header (its value is the string that identifies the browser being used):

Mozilla/5.0 (compatible; MSIE 11.0; Windows NT 6.1; Win64; x64; Trident/5.0)'+(select*from(select(sleep(20)))a)+

The start looks reasonable (it’s apparently Microsoft Internet Explorer 11) but the agent strings ends with '+(select*from(select(sleep(20)))a)+. The attacker is attempting a SQL injection inside the User-Agent value.

It’s common to see SQL injection in URIs and form parameters, but here the attacker has hidden the SQL query select * from (select(sleep(20))) inside the User-Agent Continue reading

Label Switched Multicast – Q&A

This post is the last one I’m planning in this series on Label Switched Multicast (LSM). The questions & answers below are meant to expand on topics from the previous posts or address topics that weren’t mentioned in the previous posts at all.

If you’re not familiar with LSM yet then this Q&A likely won’t make much sense to you and I recommend you go back and read through the previous posts.

Please post a comment if one of the answers isn’t clear or you have additional questions!

How can the mapping between a (*,G) or (S,G) and a Multicast Distribution Tree be found?

If you have a (*,G) or an (S,G), the following commands will show you which MDT is being used through the MPLS core. I find the easiest place in the network to check the mapping between a (*,G) or (S,G) and an MDT is on the Ingress PE. Two tables hold the mapping:

1 – the MFIB:

PE1#show ip mfib vrf BLUE 239.3.3.3
[...]
VRF BLUE
 (*,239.3.3.3) Flags: C
   SW Forwarding: 0/0/0/0, Other: 0/0/0
   Tunnel0 Flags: A
   Lspvif0, LSM/2 Flags: F NS

IDG Contributor Network: Kinvey mobilizes SAP apps

Kinvey has long been a mover and shaker in the Mobile Backend as a Service (MBaaS) world. That somewhat obscure acronym actually stands for something pretty important—the enabling of mobile applications. As the world increasingly demands data and applications to be accessible anywhere and anytime, mobile applications become even more important. But if you're an enterprise CIO or IT leader with a bunch of conflicting priorities, the last thing you want to do is wrangle the infrastructure and foundational aspects of building mobile apps. This is where Kinvey comes in.To read this article in full or to leave a comment, please click here

BGP: The Application Networking Dream

There was an interesting article last week from Fastly talking about using BGP to scale their network. This was but the latest in a long line of discussions around using BGP as a transport protocol between areas of the data center, even down to the Top-of-Rack (ToR) switch level. LinkedIn made a huge splash with it a few months ago with their Project Altair solution. Now it seems company after company is racing to implement BGP as the solution to their transport woes. And all because developers have finally pulled their heads out of the sand.

BGP Under Every Rock And Tree

BGP is a very scalable protocol. It’s used the world over to exchange routes and keep the Internet running smoothly. But it has other power as well. It can be extended to operate in other ways beyond the original specification. Unlike rigid protocols like RIP or OSPF, BGP was designed in part to be extended and expanded as needs changes. IS-IS is a very similar protocol in that respect. It can be upgraded and adjusted to work with both old and new systems at the same time. Both can be extended without the need to change protocol versions Continue reading
