Auditing network configurations with Nelkit

Audit Checklist Form

Even if you have tools in place to automate your network configuration, there’s a good chance that someone has made some manual changes. Perhaps some of your routers were overlooked the last time you send out that access-list, or a new site has been deployed using an old template. In those situations you want to audit the configuration of your network devices. Network configuration audit is one of the features of Nelkit.

DARPA: Show us how to weaponize benign technologies

The Defense Advanced Research Projects Agency was created years ago because the US didn’t want to be surprised again by any major new technological developments (specifically in response to the surprise launch of Sputnik in 1958) and ensure that the US should do any surprising.+More on Network World: The weirdest, wackiest and coolest sci/tech stories of 2015+With that in mind the agency is launching a potentially scary program called “Improv” that looks at what DARPA calls today’s “bustling tech marketplace with an inventor’s eye and imagine how easily purchased, relatively benign technologies might be converted into serious security threats.”To read this article in full or to leave a comment, please click here

Microsoft slips Windows 10 upgrade ads into Internet Explorer security patch

Microsoft is adding a new weapon to its aggressive Windows 10 push—or at least it appears that it is.Earlier in the week, Microsoft added what sounds a lot like an advertisement for Windows 10 to its Patch Tuesday release for Internet Explorer, bundling it in with a critical security patch. The new update affects only Windows 7 and 8.1 PCs and brings an upgrade prompt to Internet Explorer 11.In its description of update KB3146449, Microsoft says it “adds functionality to Internet Explorer 11 on some computers that lets users learn about Windows 10 or start an upgrade to Windows 10.” Or as we common folk call it, an ad.To read this article in full or to leave a comment, please click here

How to use deep learning AI to detect and prevent malware and APTs in real-time  

This column is available in a weekly newsletter called IT Best Practices.  Click here to subscribe.  The number of new malware variations that pop up each day runs somewhere between 390,000 (according to AV-TEST Institute) and one million (according to Symantec Corporation). These are new strains of malware that have not been seen in the wild before.Even if we consider just the low end figure, the situation is still dire. Especially when it comes to advanced persistent threats (APTs), which are the most sophisticated mutations of viruses and malware, which are very effective at going completely undetected by many of the cybersecurity technologies in use today. Even security experts tell organizations to be prepared for "when" and not "if" an attack is successful.To read this article in full or to leave a comment, please click here

Facebook’s Open Compute Project helps competitors build hyperscale data centers together

The conversion from free to paid registration and a spike in Open Compute Project Summit keynote attendance signaled that open hardware innovation is trending up. Summit attendees are companies like Facebook that buy land, build big data center buildings and fill them with commodity computing and networking hardware. Their mission is to build hyperscale, hyperefficient infrastructure that is flexible in handling workloads and agile in delivering new services in minutes. Jason Taylor, OCP CEO, introduced Google’s Vice President of Infrastructure Urz Hölz as a surprise last OCP Summit keynote with Apple-like “wait there’s still more” showmanship. Hölz presented his team's open source hardware submissions, a new approach to powering the ocean of servers used in hyperscale web company data centers operated by Facebook and Google at a more power efficient 45V instead of 12V and a new rack design.To read this article in full or to leave a comment, please click here

Two-year-old Java flaw re-emerges due to broken patch

A patch for a critical Java flaw released by Oracle in 2013 is ineffective and can be easily bypassed, security researchers warn. This makes the vulnerability exploitable again, paving the way for attacks against PCs and servers running the latest versions of Java.The flaw, tracked as CVE-2013-5838 in the Common Vulnerabilities and Exposures (CVE) database, was rated by Oracle 9.3 out of 10 using the Common Vulnerability Scoring System (CVSS). It can be exploited remotely, without authentication, to completely compromise a system's confidentiality, integrity and availability.To read this article in full or to leave a comment, please click here

Justice Department slams Apple’s ‘corrosive’ rhetoric in its latest court filing

UPDATE: March 10, 2016, 3:46 p.m. Pacific—In a conference call Thursday afternoon, Apple’s SVP and chief legal counsel Bruce Sewell said, “The tone of the brief reads like an indictment,” and in 30 years he’s never seen a brief trying so hard “to smear” someone. “It should be deeply offensive to everyone who reads it.”“Corrosive rhetoric” could be this week’s “dormant cyber pathogen,” the latest salvo in the government’s attempt to paint Apple as unreasonable for refusing to craft a new version of iOS so law enforcement can brute-force an iPhone 5c used by San Bernardino shooter Syed Rizwan Farook.To read this article in full or to leave a comment, please click here
