How will Dell justify its massive payout for EMC?

Dell's $67 billion acquisition of EMC stacks up as the largest technology deal in history. But if Michael Dell is gobbling up storage giant EMC in an attempt to stem the tide of movement from on-premise proprietary data centers to the cloud, it might be too little too late. Aside from merely bulking up, what exactly is Dell trying to do with EMC? If he hopes to leverage his new toy and its 83% stake in VMware to move deeper into the cloud, then this deal could end up justifying its enormous price tag. In a conference call about the deal, EMC CEO Joe Tucci reportedly claimed that being part of Dell as a private company would speed the development of cloud-based technologies.To read this article in full or to leave a comment, please click here

Even if you’re not in healthcare, use HIPAA to safeguard that cloud app

 If you’re thinking about migrating a highly sensitive application to the cloud, consider using HIPAA requirements as a way to vet potential providers.

Federal law requires organizations dealing with private health information to adhere to strict security guidelines defined by the Health Insurance Portability and Accountability Act (HIPAA). Given that HIPAA regulations are an excellent risk-management strategy, non-healthcare companies can use a HIPAA-compliant strategy to protect sensitive information like credit card numbers and private customer information.

HIPAA compliance requires businesses to “maintain reasonable and appropriate administrative, technical, and physical safeguards for protecting e-PHI (Electronic Personal Health Information),” but this could apply to any dataset. At a high level, here’s what you get with HIPAA compliance:

VMware brings Michigan to Europe to boost virtual networking

VMware is taking Michigan to Europe as it works to make networking as secure in the hybrid cloud as it can be in a private datacenter. At its VMworld Europe conference, it unveiled new features and tools to make it easier to roll applications out to its unified hybrid cloud platform, expanding the range of management functions available on its public cloud, vCloud Air, which can be linked with private clouds using vSphere. The company also previewed a new technology, Project Michigan, that can deploy a secure enterprise gateway across vCloud Air offerings, including Disaster Recovery and Dedicated Cloud services. It will support VM migration and network and policy extension with low downtime through Hybrid Cloud Manager. It can be used to spin up thousands of virtual machines with secure connectivity on demand, it said.To read this article in full or to leave a comment, please click here

Google Graveyard: What Google has killed off in 2015

Six feet deepGoogle is truly a company that has more technology and products than it can handle sometimes, and in 2015 the company with the recent name change shed a host of tools and products to enable it to focus on more pressing needs. Here’s a look back at what Google this year has offed or announced plans to off (To go back even further, check out 2014’s Google Graveyard.)To read this article in full or to leave a comment, please click here

To scare people better, Android ransomware gets a snazzy UI

Hackers are like any other coders: they want to built better software, even if it's a program that merely aims to extract a ransom from a hapless Android user.Symantec said it has seen a new version of the Porn Droid ransomware that uses Google's custom-built design language, Material Design, to create more intimidating warnings.Discovered last year, Porn Droid purports to be an adult content viewer. If installed, it locks a device and warns that users have viewed illicit pornography and demands a ransom. The app has been seen on third-party Android application marketplaces or forums for pirated software.To read this article in full or to leave a comment, please click here

What the Dell, EMC merger really means

Despite its whopping price tag, the $67 billion Dell acquisition of EMC doesn't radically reshape the technology market. The acquisition, announced today, is not as disruptive to the tech market as, say, Oracle's purchase of Sun Microsystems, or Hewlett-Packard's acquisition of Digital Equipment Corp., companies with competitive platforms and technologies.To read this article in full or to leave a comment, please click here

Fake LinkedIn profiles lure unsuspecting users

No doubt you've received a LinkedIn invition from someone you don't know -- or you're not sure you know. Next time, you might want to think a little harder before accepting. Researchers from Dell SecureWorks Counter Threat Unit have identified a network of at least 25 well-developed LinkedIn profiles as part of a targeted social engineering campaign against individuals in the Middle East, North Africa, and South Asia. The fake profiles were linked to 204 legitimate profiles belonging to individuals working in defense, telecommunications, government, and utility sectors. A quarter of the victims worked in the telecommunications sector in the Middle East and North Africa. Fortunately, the fake profiles have already been removed from LinkedIn.To read this article in full or to leave a comment, please click here

CCNA – Operation of IP Data Networks 1.1

We kick off the CCNA series from the beginning. Operation of IP data networks is weighted as 5% in the CCNA RS blueprint. The first topic is:

1.1 Recognize the purpose and functions of various network devices such as routers, switches, bridges and hubs

Router

A router is a device that routes between different networks, meaning that it looks at the IP header and more specifically the destination IP of a packet to do forwarding. It uses a routing table which is populated by static routes and routes from dynamic protocols such as RIP, EIGRP, OSPF, ISIS and BGP. These routes are inserted into the Routing Information Base (RIB). The routes from different sources compete against each other and the best route gets inserted into the RIB. To define how trustworthy a route is, there is a metric called Administrative Distance (AD). These are some of the common AD values:

0          Connected route
1          Static route
20         External BGP
90         EIGRP
110        OSPF
115        ISIS
120        RIP
200        Internal BGP
255        Don't install

If a value of 255 is used, the route will not installed in the RIB as the route is deemed not trustworthy at all.
