Why automation doubles IT outsourcing cost savings

Outsourcing consultancy and research firm Information Services Group (ISG) this week unveiled a new research report to quantify the cost savings and productivity gains from automating IT services.The inaugural Automation Index shows improvements in productivity fueled by automation can more than double the cost savings typically derived from outsourcing IT. Total cost reduction ranged from 26 percent to 66 percent, depending on the service tower, with 14 to 28 percentage points of these savings directly attributable to automation, according to ISG. (The typical cost savings from labor arbitrage and process improvements alone range from 20 percent to 30 percent).To read this article in full or to leave a comment, please click here

Firefox blocks websites with vulnerable encryption keys

To protect users from cryptographic attacks that can compromise secure web connections, the popular Firefox browser will block access to HTTPS servers that use weak Diffie-Hellman keys.Diffie-Hellman is a key exchange protocol that is slowly replacing the widely used RSA key agreement for the TLS  (Transport Layer Security) protocol. Unlike RSA, Diffie-Hellman can be used with TLS's ephemeral modes, which provide forward secrecy -- a property that prevents the decryption of previously captured traffic if the key is cracked at a later time.However, in May 2015 a team of researchers devised a downgrade attack that could compromise the encryption connection between browsers and servers if those servers supported DHE_EXPORT, a version of Diffie-Hellman key exchange imposed on exported cryptographic systems by the U.S. National Security Agency in the 1990s and which limited the key size to 512 bits. In May 2015 around 7 percent of websites on the internet were vulnerable to the attack, which was dubbed LogJam.To read this article in full or to leave a comment, please click here

Worth Reading: The biggest attack in internet history

For a long time, Akamai offered their DOS protection service to Krebs pro bono, both as a public service and because it’s fantastic advertising. Brian is perhaps the most high-profile target for cyber-criminals: if Akamai can defend his site, they can defend anybody’s. But it would appear Brian’s latest round of reporting—including both the Israeli arrests and outing the fact that an anti-DOS service’s former owner appeared to control a huge DOS botnet—has managed to annoy someone enough to launch a DOS attack that not only disrupted Kreb’s site but actually caused disruption to Akamai’s other services! This attack was so disruptive that Akamai had to prioritize their paying customers and stop supporting Kreb’s site. —LawFare

LILEE Systems’ new fog computing platform is well suited to distributed enterprises  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  Location, location, location! It turns out that mantra is not just for the real estate market. Location is a critical aspect of fog computing as well.Cisco introduced the notion of fog computing about two and a half years ago. (See Cisco unveils 'fog computing' to bridge clouds and the Internet of Things.) This distributed computing architecture addresses the challenge of backhauling a lot of raw data generated in the field –say from thousands or millions of IoT devices – to the cloud for analysis.To read this article in full or to leave a comment, please click here

Tips to help select and manage your co-location vendor

The percentage of IT processed at in-house sites has remained steady at around 70 percent, but data points to a major shift to co-location and cloud for new workloads in the coming years.Half of senior IT execs expect the majority of their IT workloads to reside off-premise in the future, according to Uptime Institute’s sixth annual Data Center Industry Survey. Of those, 70 percent expect that shift to happen by 2020.+ Also on Network World: 10 tips for a successful cloud plan +It is hard to predict what percentage will go to public cloud, but a significant portion of those workloads will be shifting to co-location providers—companies that provide data center facilities and varying levels of operations management and support. To read this article in full or to leave a comment, please click here

The Overlay Problem: Getting In and Out

I've been researching overlay network strategies recently. There are plenty of competing implementations available, employing various encapsulations and control plane designs. But every design I've encountered seems ultimately hampered by the same issue: scalability at the edge.

Why Build an Overlay?

Imagine a scenario where we've got 2,000 physical servers split across 50 racks. Each server functions as a hypervisor housing on average 100 virtual machines, resulting in a total of approximately 200,000 virtual hosts (~4,000 per rack).

In an ideal world, we could allocate a /20 of IPv4 space to each rack. The top-of-rack (ToR) L3 switches in each rack would advertise this /20 northbound toward the network core, resulting in a clean, efficient routing table in the core. This is, of course, how IP was intended to function.

Unfortunately, this approach isn't usually viable in the real world because we need to preserve the ability to move a virtual machine from one hypervisor to another (often residing in a different rack) without changing its assigned IP address. Establishing the L3 boundary at the ToR switch prevents us from doing this efficiently.

Ransomware spreads through weak remote desktop credentials

Stolen or weak remote desktop credentials are routinely used to infect point-of-sale systems with malware, but recently they've also become a common distribution method for file-encrypting ransomware.In March, researchers discovered a ransomware program dubbed Surprise that was being installed through stolen credentials for TeamViewer, a popular remote administration tool. But the trend had started long before that, with some ransomware variants being distributed through brute-force password guessing attacks against Remote Desktop Protocol (RDP) servers since 2015.While this method of infection was initially used by relatively obscure ransomware programs, recently it has been adopted by an increasing number of cybercriminals, including those behind widespread ransomware programs such as Crysis.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Wi-Fi can be used to identify people in IoT locations

Wi-Fi signals can be used to unobtrusively identify different people at a location, such as home. It promises to replace other forms of identification in those domestic environments, Chinese scientists say.The system works by identifying body shapes along with the unique way that individuals move in a room. Those characteristics influence Wi-Fi propagation, researchers from Northwestern Polytechnical University in Xi’an claim. The Wi-Fi is affected by the people in the room, and that impact on the wireless access point can be detected and interpreted, they say.INSIDER: 5 ways to prepare for Internet of Things security threats “Each person has specific influence patterns to the surrounding Wi-Fi signal while moving indoors, regarding their body shape characteristics and motion patterns,” the team writes in an abstract to their paper, published in August.To read this article in full or to leave a comment, please click here

Researchers make progress toward computer video recognition

Computers can already recognize you in an image, but can they see a video or real-world objects and tell exactly what's going on? Researchers are trying to make computer video recognition a reality, and they are using some image recognition techniques to make that happen. Researchers in and outside of Google are making progress in video recognition, but there are also challenges to overcome, Rajat Monga, engineering director of TensorFlow for Google's Brain team, said during a question-and-answer session on Quora this week. The benefits of video recognition are enormous. For example, a computer will be able to identify a person's activities, an event, or a location. Video recognition will also make self-driving cars more viable.To read this article in full or to leave a comment, please click here
