By this point, most technology practitioners -- and nearly all security practitioners -- know about WannaCry. In fact, you might be sick of people analyzing it, rehashing it, sharing "lessons learned" about it, and otherwise laying out suggestions -- in some cases, contradictory -- about what you might do differently in the future. The level of unsolicited advice can border on the annoying.

Microsoft on Thursday said it has agreed to buy a Hexadite, which incorporates artificial intelligence in its automated responses to cyberthreats. The acquisition will help bolster the company's efforts to help commercial Windows 10 customers deal with advanced attacks on their networks, Microsoft said. The acquisition will include Hexadite's endpoint security automated remediation.

Competition in telecom price and service packages has been getting a lot of attention lately. However, network providers also have been pursuing other opportunities that consumers might miss if they're exposed only to traditional advertising. AT&T's cooperation with the U.S. government in developing a national emergency responder network is a case in point.

Information security practices are undergoing a transformation. For at least a decade, environments have been becoming less perimeter-centric: Gone are the good old days when in-line controls protected the trusted, safe interior from the "wild west" of the outside. As environments become more complex and externalized, the traditional "perimeter" loses meaning.

Crate.io has announced the general availability of the first non-beta release of CrateDB 1.0, an open source SQL database that enables real-time analytics for machine data applications. CrateDB is an SQL database alternative to NOSQL machine data management solutions. It gives mainstream SQL developers access to machine data applications that previously were available only using NoSQL solutions.

Chip manufacturer Broadcom on Wednesday announced that it would buy Brocade Communications, a major supplier of fiber channel storage area networking technology to data centers, for $5.5 billion in cash and the assumption of Brocade's $400 million debt. That represents a 47 percent premium over Brocade's closing share price last week, said Brocade CEO Lloyd Carney.

Red Hat and Ericsson on Wednesday announced an alliance meant to speed adoption of open source solutions in the information and communications technology space. The alliance will help promote a range of fully open source and production-ready cloud solutions, spanning OpenStack, software defined-networking and software-defined infrastructure, the companies said.

Happy Birthday Linux! You're 25! When Linux was born on Aug. 25, 1991, it was little more than a hobby for 21-year old Linus Torvald. Today the Linux community is estimated to be upwards of 86 million users strong. It has become the backbone of large enterprises, and it is installed in government systems and embedded in devices worldwide. It has grown into a major mainstream computing platform.

Responsibility for securing enterprise applications has been moving down the development lifecycle, and for good reason. It not only makes the enterprise more secure, but also saves companies time and money. For example, the average time to fix a vulnerability in IBM's application security solution has dropped from 20 hours to 30 minutes, according to Forrester Consulting.

The Linux Foundation on Tuesday added PNDA -- the Platform for Network Data Analytics -- to its project menagerie. PNDA provides an open source, scalable platform for next-generation network analytics. It integrates data from multiple sources on a network and works with Apache Spark to crunch the numbers in order to find useful patterns in the data more effectively.

Delta Air Lines reportedly canceled 300 flights Tuesday morning, a day after a mammoth outage that forced it to temporarily ground thousands of flights worldwide and ultimately cancel more than 400 of them. Although an update posted at 10:00 p.m. ET Monday night warned that there would be more than 100 flight cancellations and roughly 200 delays Tuesday morning, the actual numbers were worse.

"Patch your systems in a timely manner" is a mantra of security experts, but what happens when the patch well runs dry because a product's maker no longer supports it? That is a situation facing many large enterprises, and it's one that poses security risks. Between 30 percent and 50 percent of the hardware and software assets in the average large enterprise have reached their end-of-life date.

Since mobile computing put an end to the good old days when IT departments had absolute control over software deployed in the enterprise, there's been a rise in employees' use of third-party applications -- a rise that poses security risks to corporate environments. That is one of the findings in a report CloudLock released last week.

The Linux Foundation on Wednesday announced that it has taken the OpenSwitch Project under its wing. OpenSwitch last year began as a joint project of Hewlett Packard Enterprises, Broadcom, VMware, Accton, Intel and Arista. OpenSwitch is an open source, Linux-based network operating system, or NOS, that works with enterprise-grade switches from multiple vendors.

When small businesses choose an IT and support service provider, the two most important considerations are the provider's ability to include all of the company's devices and provide a comprehensive IT service plan. More than half of small businesses that use professional IT services use two or more services. However, small businesses may have to rely on multiple vendors to address their IT needs.

The Linux Foundation's Core Infrastructure Initiative project on Tuesday announced a free badge program to help foster security, quality and stability in open source software projects. Through an online app, the CII lets devs determine whether they're following best practices, generally within an hour or so. If they are, they'll receive the badge, which they can display on GitHub and other online properties.

Last year, I researched the impact of the proliferation of cloud computing on business. I know it sounds like a dry topic, but if you are a CIO or an application development manager, the results can have serious meaning. Cloud computing has deeply penetrated the enterprise and SMB ranks, and 46.3 percent of respondents said they had four or more cloud applications in use.

Canonical on Thursday launched Ubuntu 16.04, aka "Xenial Xerus," an upgrade that will be supported for the next five years. The latest version for all desktop, server and cloud editions will be available for download starting Thursday. Ubuntu 16.04 includes four major technology advancements geared toward multiplatform uses. Xenial Xerus is the sixth Long Term Support release for Ubuntu.

Greenwave Systems on Monday announced the expansion of its AXON Platform to unite mobile machine-to-machine and residential IoT networks into one fully manageable network service. Mobile carriers, telecommunications operators and service providers can use AXON for Mobile IoT to integrate a variety of communications protocols into the same standard IP-based language.

Cisco has unveiled Cloud Consumption as a Service to help enterprises discover and continually monitor public cloud use -- aka "shadow IT" -- across their systems. Shadow IT systems in an enterprise or organization expose it to security risks and hidden costs, and may give rise to compliance issues. Organizations are using up to 20 times more cloud services than IT is aware of, according to Cisco.

Juniper Networks on Sunday informed customers that recent security threats to its ScreenOS were not as widespread as initially believed. The company last week issued an alert following its discovery in ScreenOS of unauthorized code that could allow an attacker to gain administrative control of devices using Netscreen or to decrypt a VPN. The two issues are unrelated to each other.

Portfolios of task-oriented mobile apps for employees, contractors and business partners have been transforming the way enterprises conduct business, Apperian reported last week. Companies that have launched mobility initiatives have customized and deployed one or more apps that have streamlined business operations, according to the firm's analysis of 2 million app deployments.

Cisco and Ericsson on Monday announced a partnership to build out a next-generation network for smart things and the carriers and enterprises that want to support such devices. The deal plays to the companies' strengths in cloud, data center, mobility, management, networking, routing and global services, they said. Each company expects to earn about US$1 billion in revenue by 2018 from the deal.

The European Parliament on Tuesday passed Net neutrality legislation to a chorus of boos from Net neutrality proponents. The European Union has found consensus on the common principles of Net neutrality -- no blocking, no throttling and no prepaid prioritization -- said Commissioner Günther H. Oettinger. However, the rules have three major loopholes, Net neutrality supporters said.

The Linux Foundation has announced a strategic partnership with ON.Lab and its ONOS project community to develop open source network services. They will build infrastructure for software-defined networking and network function virtualization technology. The foundation will provide its global reach, experience and infrastructure to seed ONOS' growing community.

The Linux Foundation's recently published security checklist may draw more attention to best practices for protecting Linux workstations, even if IT pros do not embrace all of its recommendations. Konstantin Ryabitsev, the foundation's director of collaborative IT services, developed the list for the use of LF remote sysadmins, to harden their laptops against attacks.

Shadow IT -- the use of unauthorized online services by company employees -- is a concern of cyberwarriors charged with defending business systems against network attacks. There's new evidence that those concerns are justified. A new attack vector on business systems leverages the synchronization features of services like Dropbox and Google Drive to perform malicious mischief.

The OpenDaylight Project this week announced that AT&T, ClearPath Networks and Nokia Networks have joined, bringing its membership total to 359. OpenDaylight is a collaborative open source project hosted by the Linux Foundation. Its goal is twofold: accelerate the adoption of software-defined networking; and create a solid foundation for network functions virtualization.

With so many cybersecurity pros drowning in an ever-rising tide of hack attacks on their computer systems, an emerging approach to defending those systems may be the life preserver they've been looking for. The approach doesn't involve beefing up perimeter defenses, carefully scrutinizing network traffic, or applying analytics to employee behavior.

The results of a recent survey on container usage trends suggest that a deployment surge is likely within the next two years -- but also that companies have serious concerns about container security, certification and skills. The survey, commissioned by Red Hat and conducted by TechValidate, assessed enterprise adoption plans for application containers.
