Apple quashes 3 zero-days with emergency Mac update

Apple yesterday issued an emergency security update for the Mac, patching the same trio of vulnerabilities the company fixed last week on the iPhone. According to one of the groups that first revealed the flaws, the vulnerabilities could have been "weaponized" for use against OS X, the Mac's operating system. The out-of-band update was aimed at OS X El Capitan (aka 10.11) and Yosemite (10.10), the 2015 and 2014 editions, respectively. Older versions, including 2014's OS X Mavericks, went unpatched: Apple is nearing the release of its annual Mac operating system upgrade and thus the end of support for the edition of three years ago. Like the urgent update Apple released last week for the iPhone -- iOS 9.3.5 -- the Mac patches quash three bugs, two in the operating system's kernel and the third in the Safari browser.To read this article in full or to leave a comment, please click here

U.S. cloud vendors adjust to Snowden effect, Privacy Shield

When whistleblower Edward Snowden shocked the world in 2013 by revealing that the NSA was allegedly siphoning data from U.S. internet companies, pundits proclaimed that winter was coming for American cloud vendors in Europe. Evidence now suggests those fears may have been overblown.IDC said this month that U.S. cloud vendors have increased their combined cloud infrastructure revenue two-and-a-half-times in Western Europe, topping $2 billion since the Snowden Effect was supposed to freeze the market. Amazon Web Services (AWS), Microsoft, Alphabet’s Google and IBM increased their market share by a third in the region, hitting 40 percent in 2015.To read this article in full or to leave a comment, please click here

Microsoft bug bounty program adds .NET Core and ASP.NET Core

Microsoft has expanded its bug bounty programs to cover the open-source .NET Core and ASP.NET Core application development platforms.The .NET Core and ASP.NET Core technologies are used to create server applications that can run on Windows, Linux, and Mac. The ability to write code once and have it run on multiple platforms have made these technologies popular with enterprise software developers.Microsoft will pay monetary rewards between US$500 and $15,000 for critical vulnerabilities in the RTM (release to manufacturing), Beta, or RC (release candidate) releases of these platforms.Flaws in Microsoft's cross-platform Kestrel web server are also covered by the new bug bounty program, as well as vulnerabilities in the default ASP.NET Core templates provided with the ASP.NET Web Tools Extension for Visual Studio 2015 or later.To read this article in full or to leave a comment, please click here

Multi-site with Cross-VC NSX: Consistent Security and Micro-segmentation Across Sites

Several posts have been written prior on multi-site with Cross-VC NSX describing the fundamentals, use cases, deployment models, and flexibility Cross-VC NSX provides. In this post, we focus on the security benefits of a multi-site Cross-VC NSX solution.

Prior Cross-VC NSX Blogs:
Cross-VC NSX: Multi-site Deployments with Ease and Flexibility
NSX-V: Multi-site Options and Cross-VC NSX Design Guide
Enhanced Disaster Recovery with Cross-VC NSX and SRM
Cross-VC NSX for Multi-site Solutions

So, why multi-site with Cross-VC NSX? The following five reasons should be enough for you to seriously consider Cross-VC NSX as a solution for your multi-site needs:

1.) Centralized Management
Centralized management of security policies across multiple vCenter domains/sites. You have one central location to configure security policies and only write the security policy once, which is then applied across all vCenter domains/sites.

Figure 1 Central Management of Security Policies Across Sites from Primary NSX Manager

2.) Consistent Security Across vCenter Domains/Sites
Consistent security policies across vCenter domains/sites provided automatically by Cross-VC NSX enables enhanced workload mobility. Security policies are configured on the primary NSX Manager and automatically synced to the secondary NSX Managers providing for uniform security across all sites.

Using BGP in Leaf-and-Spine Fabrics

In the Leaf-and-Spine Fabric Designs webinar series we started with the simplest possible design: non-redundant server connectivity with bridging within a ToR switch and routing across the fabric.

After I explained the basics (including routing protocol selection, route summarization, link aggregation and addressing guidelines), Dinesh Dutt described how network architects use BGP when building leaf-and-spine fabrics.
