Automating Security Group and Policy Creation with NSX REST API

As we’ve seen in many of the prior posts, VMware NSX is a powerful platform decoupling networking services from physical infrastructure. NSX effectively enables logical networking and security within a virtualized environment; this brings many of the same benefits we’re familiar with gaining from server virtualization such as flexibility, faster provisioning, better utilization of hardware, cost savings, decreased downtime, etc. One of the major benefits of the software approach that NSX brings is the ability to automate easily via REST API. In this post, we’ll take a look at a simple yet realistic use case focused around security where automation can help.  Continue reading

FBI is cracking an iPhone in an Arkansas murder case

Now that it has found a way to do so for its own purposes in a California terrorism case, the FBI is helping Arkansas prosecutors break into an iPhone and iPad.This time it’s to look for evidence in a murder trial, and it’s without asking Apple for help to crack the iOS devices. Instead prosecutors in Faulkner County, Ark., asked the FBI to take a shot at it, given its recent success breaking into the phone used by a terrorist in San Bernardino, Calif., according to the Associated Press.The FBI is also helping break into an iPod related to the case, the AP says.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Grow lunar-based solar panels to eliminate fossil-fuel reliance, says kid

Nearly 200 countries signed the fossil fuel ramp-down agreement in Paris at the end of last year. New goals are now in place to end the use of fossil fuels worldwide. No more global warming could be in the cards.

Sounds good, right? Well it probably is, but there’s a slight problem: Just how are we going to power our smartphones, homes, factories, and Internets without coal and gas? That’s a lot of solar panels and windfarms needed—and needed quickly.

One high school kid reckons he’s got the answer, reported Popular Science magazine a few weeks ago: Just stick a bunch of solar panels on the moon and beam the power back down to Earth by microwave.

Palo Alto Integration with Cisco ACI and OpenStack on Software Gone Wild

A while ago Christer Swartz explained how a Palo Alto firewall integrates with VMware NSX. In the meantime, Palo Alto announced integration with Cisco ACI and OpenStack, and it was time for another podcast with Christer deep-diving into the technical details of these integrations.

Spoiler: It’s not OpFlex. For more details, listen to Episode 53 of Software Gone Wild

Reddit’s removal of ‘warrant canary’ could hint at US demand for its user data

Reddit has removed a notice, known as a warrant canary, from its transparency report for 2015, suggesting that it may have received a secret national security order for user data.The removal of the warrant canary is a reminder to users that their online communications could be the target of investigators.The most controversial of the orders is the National Security Letter, which gives the government the authority to compel the production of customer records held by telephone companies, Internet service providers and other electronic communications service providers.Companies, who have been asked for user data by the government, are usually served the requests under a “gag order” that prohibits them from disclosing the request for data.To read this article in full or to leave a comment, please click here

Building Web front end for Python scripts with Flask

Recently I revived my relationship with Python in an effort to beat routine tasks appearing here and there. So I started to write some pocket scripts and, luckily, was not the only one on this battlefield – my colleagues also have a bunch of useful scripts. With all those pieces of code sent in email, cloned from repos, grabbed on network shares

CloudFlare aims to block fewer legitimate Tor users

CloudFlare is tweaking its systems to make it easier for legitimate Tor users to access websites that use its network to deliver content.Tor users have complained that CloudFlare-powered websites too frequently display CAPTCHAs, a security gate designed to stop automated web bots and abuse. CAPTCHAs are the squiggly text or puzzles you have to solve to prove you're a real human.The problem is that many computers employing Tor are engaged in abusive activity, resulting in CloudFlare displaying CAPTCHAs when it detects a computer using the Tor network.Legitimate Tor users thus have a poor browsing experience given the wide use of CloudFlare's CDN.To read this article in full or to leave a comment, please click here

‘No viruses! Honest!’

These "free USB sticks" were left for the taking in our break room here at Network World headquarters.And, even though I’m reasonably certain I know who left them, there’s no way I’m falling for the old “No viruses! Honest!” trick. To read this article in full or to leave a comment, please click here

FCC votes for strict new broadband privacy rules

The U.S. Federal Communications Commission has taken a major step toward new regulations requiring ISPs to get customer permission before using or sharing their Web-surfing history and other personal information.The FCC voted 3-2 Thursday to approve a notice of proposed rule-making, or NPRM, the first step toward passing new regulations, over the objections of the commission's two Republicans.The proposed rules, which will now be released for public comment, require ISPs to get opt-in permission from customers if they want to use their personal information for most reasons besides marketing their own products.To read this article in full or to leave a comment, please click here

Worth Reading: A yot of YANG

The YANG Model Coordination Group has been spending time on the inventory of those YANG models in the industry, the tooling aspects, the help with the compilation, the training & education (NETCONF, YANG, pyang), the coordination across SDOs/opensource, the model coordination with the IETF. On the tooling front, the YANG model extraction and compilation is now integrated in the IETF draft submission tool, thanks to Henrik Levkowetz. So no more excuses for producing YANG models that don’t compile. -via the IETF blog

IDG Contributor Network: What is the future of mobile communications app security

We are well on our way to a world where communications traffic between mobile apps will be completely secure. Whether voice or text, monitored traffic will be encrypted and uncrackable, even with the cooperation of the app or device developers.A recent example, Facebook’s WhatsApp is reportedy causing law enforcement concern, as it appears to be impervious to decryption efforts. Government legislation forcing vendors to incorporate some type of backdoor password seems to be the only alternative to living with this new reality, but legislation may be unenforceable in the international context of app development and distribution.To read this article in full or to leave a comment, please click here

Hackers can abuse the iOS mobile device management protocol to deliver malware

Starting with iOS 9, Apple has tried to make it harder for attackers to trick users into installing unauthorized apps on their devices by abusing stolen enterprise certificates. However, it left one door open that attackers can still exploit: the protocol used by mobile device management products.In a presentation at the Black Hat Asia security conference on Friday, researchers from Check Point Software Technologies will demonstrate that the communication between MDM products and iOS devices is susceptible to man-in-the-middle attacks and can be hijacked to install malware on non-jailbroken devices with little user interaction.Apple's tight control over the iOS App Store has made it hard, but not impossible, for attackers to infect iOS devices with malware.To read this article in full or to leave a comment, please click here
