Samsung sued for not updating Android on older phones

The Dutch Consumers' Association (DCA), or Consumentenbond as it is known in its native land, is suing Samsung for not providing timely software updates to older models of its Android smartphones. The move was driven in part because Samsung has such a strong presence in Holland, and because Samsung is pretty bad about supporting old phones, as I've learned through personal experience.According to DCA's own research (PDF file), at least 82% of Samsung smartphones available in the Dutch market examined had not received any software updates to the latest version of Android in two years.To read this article in full or to leave a comment, please click here

Despite rhetoric, DoJ, NSA still seek backdoors

The U.S. took its encryption argument international last week, with Attorney General Loretta Lynch telling the World Economic forum that it doesn’t want to put security backdoors into encrypted communications, it just wants to vendors and service providers to decrypt when ordered to by a court.That ignores that facts that vendors and providers can’t decrypt unless there is a backdoor of some sort, and that any backdoor undermines the security and therefore the value of encryption.It’s a case of the Department of Justice – via Lynch and FBI Director James Comey – trying to steer clear, at least technically, of demanding backdoors, but it’s all a semantic game. Earlier, Comey stopped using the term backdoor and asked for front-door access to decryption instead. Backdoor had become too much of a flashpoint, even though a front-door is exactly the same as a backdoor from a technology standpoint.To read this article in full or to leave a comment, please click here

Talking NVMe, 3DXpoint and Networking

The IT Storage market is going through a lot of change. New silicon designs from Intel & Micron branded 3D Xpoint are impacting the short term future of the “all flash array” market. Intel has developed NVMe so that that speed of accessing this fancy new storage can be realised because the 30-year old SCSI/NFS/Fibrechannel protocols […]

Response: Doing No Harm

Ivan posted here: I’ll take ownership of the statement because at least it sounds like something I have discussed on the podcast and, sadly, because there aren’t that many networking podcasts. The comment is in relation to the purpose of a stateful firewall when compared to a stateless firewall aka access lists. I do think that […]

Design of a Modern Cache

This is a guest post by Benjamin Manes, who did engineery things for Google and is now doing engineery things for a new load documentation startup, LoadDocs.

Caching is a common approach for improving performance, yet most implementations use strictly classical techniques. In this article we will explore the modern methods used by Caffeine, an open-source Java caching library, that yield high hit rates and excellent concurrency. These ideas can be translated to your favorite language and hopefully some readers will be inspired to do just that.

Eviction Policy

A cache’s eviction policy tries to predict which entries are most likely to be used again in the near future, thereby maximizing the hit ratio. The Least Recently Used (LRU) policy is perhaps the most popular due to its simplicity, good runtime performance, and a decent hit rate in common workloads. Its ability to predict the future is limited to the history of the entries residing in the cache, preferring to give the last access the highest priority by guessing that it is the most likely to be reused again soon...

6 analytics trends that will shape business in 2016

In its recently released Analytics Trends 2016 report, consulting firm Deloitte predicts six major trends will significantly shape business in 2016."Business leaders continue to face many varying challenges and opportunities, and staying ahead of these trends will have a lasting impact on how their organizations will operate in the future," says John Lucker, principal, Deloitte Consulting. "By going on the offensive with issues such as cybersecurity, organizations are making a strategic shift in the way they operate. Concurrently, the widening data scientist talent gap could be a business growth barrier. One thing is certain: effectively using analytics is essential in delivering insights that help achieve new levels of innovation and value."To read this article in full or to leave a comment, please click here

Why VCE customers should embrace, not fear, Dell’s merger with EMC

2015 was filled with many big technology acquisitions, the most notable of which was Dell dropping a whopping $67 billon for EMC. One of the most interesting questions that has been raised regarding the acquisition is what happens to the EMC Federation companies, most notably, VCE (disclosure: VMware is a client of ZK Research).VCE was founded as a joint venture between three market-leading vendors – VMware, Cisco, and EMC – to deliver a converged solution comprised of products from the three companies. In October of 2014, VCE announced it was acquiring controlling interest in the JV from Cisco (VMware was a minority shareholder).To read this article in full or to leave a comment, please click here

Worth Reading: Light at the end of the silicon

Silicon photonics has emerged as one of those areas of such far-reaching potential that its challenges and benefits tend to be clouded in generalities. Light as the main medium does indeed promise to alter fields including biological and chemical sensing, navigation, radio frequency sensing, communications, but for our purposes here, the potential within large-scale computing is of greater interest. -via the next platform

Time to Consider User Behavior Analytics (UBA)

In 2012, I did an extension research project on big data security analytics. My thesis was that big data tools like Hadoop, Mahout, MapReduce, and Pig would greatly enhance in-depth historical cybersecurity investigations beyond anything provided by SIEM tools. In retrospect, I believe my assumptions were correct, but the market remains in an early stage of development even today. While general use of big data security analytics is still in its genesis phase, there appears to be an increasingly popular use case in cybersecurity: User Behavior Analytics (UBA). UBA is roughly defined as the analysis of all activities related to individual users, covering devices, processes, applications, network sessions, and data consumed and utilized. UBA builds a data analytics model where all log files, endpoint and network forensics, authentication requests, and data access actions are aligned with individual users themselves. To read this article in full or to leave a comment, please click here

Critical vulnerabilities patched in Magento e-commerce platform

If you're running an online shop based on the Magento e-commerce platform, it's a good idea to update it as soon as possible. The latest patches fix critical vulnerabilities that could allow attackers to hijack administrative accounts.One issue was discovered by researchers from Web security firm Sucuri and stems from improper validation of email addresses in the customer registration form.The flaw allows a malicious user to include JavaScript code in the email field, leading to a so-called stored cross-site scripting (XSS) attack. The JavaScript code is saved along with the form and is triggered when the user account is listed in the website's back-end panel.To read this article in full or to leave a comment, please click here

Securing BGP: A Case Study (1)

What would it take to secure BGP? Let’s begin where any engineering problem should begin: what problem are we trying to solve?

A small collection of autonomous systems

In this network—in any collection of BGP autonomous systems—there are three sorts of problems that can occur at the AS level. For the purposes of this explanation, assume AS65000 is advertising 2001:db8:0:1::/64. While I’ve covered this ground before, it’s still useful to outline them:

  1. AS65001 could advertise 2001:db8:0:1::/64 as if it is locally attached. This is considered a false origination, or a hijacked route.
  2. AS65001 could advertise a route to 2001:db8:0:1::/64 with the AS path [65000,65001] to AS65003. This is another form of route hijacking, but instead of a direct hijack it’s a “one behind” attack. AS65001 doesn’t pretend to own the route in question, but rather to be connected to the AS that is originating the route.
  3. AS65000 could consider AS65003 a customer, or rather AS65003 might be purchasing Internet connectivity from AS65000. This would mean that any routes AS65000 advertises to AS65003 are not intended to be retransmitted back to AS65004. If, for instance, 2001:db8:0:1::/64, is advertised by AS65000 to AS65003, and AS65003 readvertises it to AS65004, AS65003 would be an unintentional transit AS in the Continue reading

CISOs should take security training seriously

In many ways, security awareness training exemplifies the way information security is seen and tackled by senior management.A once-a-year, classroom-based approach may be traditional, with security updates and warnings posted on walls and the Intranet, but it is also a sign of a tick-box, compliance-driven approach to security. It is often done to appease industry regulators, PCI and data protection authorities, and the training can offer relatively basic – arguably condescending- advice.But times are changing. The threat landscape is growing with the arrival of millions of mobiles and wearables, each with their own IP address, while organized crime and nation-state APT groups are looking at new ways of compromising victims. From exploit kits and Trojans to ransomware, phishing and social engineering scams – the criminal game has moved on.To read this article in full or to leave a comment, please click here

Telephonic DoS a smokescreen for cyberattack on Ukrainian utility

The late December telephonic denial-of-service attack against a Ukrainian power company was a smokescreen to cover up a cyber attack, experts say."This is one of the more common reasons why these attacks are done," said Rene Paap, product marketing manager at security vendor A10 Networks.According to Paap, telephonic DoS attacks have been around for a while, but don't get as much attention as the big DDoS attacks.Just like a regular DDoS attack, telephonic DoS works by overwhelming the victim's call center with so many fake phone calls that legitimate calls can't get through.[ ALSO ON CSO: Ukrainian power companies are getting hit with more cyberattacks ]To read this article in full or to leave a comment, please click here
