IDG Contributor Network: A patchwork quilt of IoT security

The Internet of Things (IoT) presents a security threat. A key point of my last article is that manufacturers do not have the right incentives. But all is not lost. With a little ingenuity, we can make a quilt of independent pieces that can nevertheless turn out to offer good security coverage.The term “patchwork quilt” is often used pejoratively to describe something that is made up of an assortment of other parts. Yet it is worth remembering that a well-made quilt is still functional, durable and beautiful. And quilts are often made collaboratively in quilting bees. We need this sort of approach to network security.To read this article in full or to leave a comment, please click here

It is remarkable how quickly technology giants like Facebook, Google, Amazon and others became newsmakers No1 in the networking area. Seriously, for 5 breaking news from these guys its only 1 serious announcement from vendor-camp. Keeping the ratio in favor of tech giants meet the roundup of the recent Facebook' even called Disaggregate: Networking. [1]

Cisco patches critical flaw in Prime Home device management server

Cisco Systems has fixed a critical vulnerability that could allow hackers to take over servers used by telecommunications providers to remotely manage customer equipment such as routers.The vulnerability affects Cisco Prime Home, an automated configuration server (ACS) that communicates with subscriber devices using the TR-069 protocol. In addition to remotely managing customer equipment, it can also "automatically activate and configure subscribers and deliver advanced services via service packages" over mobile, fiber, cable, and other ISP networks."A vulnerability in the web-based GUI of Cisco Prime Home could allow an unauthenticated, remote attacker to bypass authentication and execute actions with administrator privileges," Cisco said in its advisory.To read this article in full or to leave a comment, please click here

Cisco: Faulty clock part could cause failure in some Nexus switches, ISR routers, ASA security appliances

Cisco this week issued a notice that faulty clock timing chips in some of its switches, routers and security appliances could fail after about 18 months of service – causing those devices to crash and not recover.The notice includes some of the company’s most widely deployed products, from certain models of its Series 4000 Integrated Services Routers, Nexus 9000 Series switches, ASA security devices to Meraki Cloud Managed Switches. Clock components are critical to the synchronization of multiple levels of a given device.+More on Network World: Cisco amps-up Tetration platform with better security, reduced footprint, AWS cloud option+To read this article in full or to leave a comment, please click here

IDG Contributor Network: Service insertion—Why it’s so important

One of the major challenges that’s long faced enterprise network is the ability to spin up new network services. SD-WANs make this a lot easier through service insertion and service chaining.Suppose for a moment you want to construct a secure perimeter around your compute resources in your data center and Amazon Web Services (AWS) implementation. Normally, you’d introduce a firewall and an Intrusion Detection System (IDS) into each location. That way, should a security incident happen in one location, such as a malware outbreak or a denial of service attack, you would be able to mitigate that event without any reengineering work. To read this article in full or to leave a comment, please click here

Outlook for iOS speeds up work with third-party add ins

Users of Microsoft's Outlook app for iPhone and iPad can now get work done quicker using third-party integrations.As of Thursday, Outlook for iOS supports add-ins, which let software companies build extensions to their own products that interact with emails in Outlook on a user’s smartphone and tablet. At launch, the app supports add-ins from Evernote, GIPHY, Nimble, Trello and Smartsheet, in addition to those that Microsoft has created.For example, users will be able to translate emails using a Microsoft Translator add-in, add cards to a Trello board straight from their email and quickly reply to an email thread with a funny animated GIF.To read this article in full or to leave a comment, please click here

Worth Reading: Lazy thinking and modularity

There are two flaws in the Modularity Always Wins theory. In order to succeed, “disruptive modularity” needs a stable architecture with well-defined and documented boundaries. Module innovators need to be able to slide their creations into place without playing havoc with the rest of the edifice. This is how it worked in the Wintel PC world…sort of. In PC reality, as many of us have experienced, the sliding in and out of modules wasn’t so neat and often landed us in Device Driver purgatory. In the mid-nineties, one Microsoft director told me that the Redmond company actually spent more engineering resources on drivers than on Windows’ core software. —Monday Note

IDG Contributor Network: CRM and contact center are on a collision course

The arcs of two industries, customer relationship management (CRM) and contact center, are about to entangle. More descriptively, these two industries are on a collision course. Consequences include exciting new innovations in customer experience and dramatic market-wide change.Changing times Propelled in an age of big data and artificial intelligence (AI), CRM is entering the industry’s platinum age. At the same time, contact center is facing disruption as newer communications protocols come to broader acceptance, old guard companies face transitions, and ways of deploying applications—cloud for one—accelerate in adoption.  + Also on Network World: How to conquer a CRM monster + The two industries have existed in the same universe, that of the key ways that customers interact with an enterprise, but for the most part it's as if they have occupied different dimensions. As CRM matured, it was embraced by marketing, sales and service delivery. CRM and contact center would occasionally interact, such as when telephony call controls were added to a CRM screen or when a service call turned into an upselling opportunity. However, true synergies have seldom really gelled.To read this article in full or to leave a comment, please click here

Arista enables visibility at cloud speed

You can’t manage what you can’t see. That phrase that has been used over and over again with network managers as they look to get a better handle on the goings on in their networks. The problem is pervasive visibility is hard. Collecting information from multiple systems, rolling it up into an aggregated view and then trying to do some kind of manual machine learning on it is next to impossible. I suppose if Mr. Spock were running the network, things might be OK. But the last time I checked, the U.S. wasn’t accepting H1-Bs from Vulcan, so humans will have to do. + Also on Network World: Cloud monitoring: Users review 5 top tools + The need for visibility has created a rising tide in the network packet broker market, and most of these do a fine job in the enterprise space, but the RISC-based processers that some of them use do not operate at cloud speeds when there are multiple 100 Gig-E connections that need to be tapped. I want to be clear that I’m making distinction between an enterprise monitoring cloud traffic and an actual cloud provider monitoring its internal traffic. The latter is Continue reading

IBM Watson wants to do your tax returns

If anyone can make sense of the over 74,000 pages of the US tax code, IBM’s Watson can. Or at least that’s the plan as Big Blue has teamed up its Watson cognitive supercomputer with the tax return specialists at H&R Block to help customers with tax filing options.As part of the first phase of the collaboration, H&R Block and IBM development teams trained tax language Watson, first applying the technology to the myriad questions and topics discussed during the return filing process.The service uses cloud-based Watson services to understand context, interpret intent and draw connections between clients’ statements and relevant areas of their return, the companies said.To read this article in full or to leave a comment, please click here
