Checking in with Cisco’s Metacloud


Last year Cisco bought Metacloud to create an OpenStack Private Cloud division:

Like almost all technology vendors there, Cisco is looking to build its cloud story.A key part of this strategy last year was the acquisition of Metacloud, a company that specializes in offering private clouds based on OpenStack . I sat down with director Scott Sanchez Metacloud strategy recently to catch up on how you exercise.There is a big difference between Metacloud and many other private cloud offerings on the market: Cisco will handle your private cloud for you. The controller hardware - which is composed of a pair of Cisco UCS servers, a router ASR and Nexus 9000 switch - is located in the data center customers, but is managed remotely by Cisco OpenStack Private Cloud Team. In fact, Cisco centrally manages all Metacloud private clouds.

The idea is to give the public an experience like Amazon Web Services cloud, where the company manages all the necessary software for the cloud. But the hardware is in the customer premises. Beyond the controller hardware, customers can use their existing infrastructure for scalability of private cloud, or Cisco UCS can use additional servers or black-boxes. When developers need a virtual machine or additional storage, rotating upward from Metacloud. Cisco equipment is constantly releasing updates to the software in the cloud, which is based on OpenStack, add new features.

It's not a completely unique approach to the market: IBM recently bought OpenStack BlueBox provider that has a similar model that doubles as a private cloud service. Newcomer to the market Platform9 has a similar remote management private cloud offering. It is in stark comparison to a private cloud VMware offering, that provides management tools for customers to rotate and manage their own private clouds.

The ultimate goal is for Cisco to connect these Metaclouds with cloud offerings from Cisco Intercloud - the company's effort to build a series of connected public cloud offerings in the market. There integrations for customers to link Meta Cloud AWS or Microsoft Azure tambiƩn.Esperar to see progress over Intercloud Meta Cloud and move forward - that seems to be an area of Cisco is committed to under the new leadership of CEO Chuck Robbins .

Cisco: Overcrowded Security Market Needs More M&A


Cisco Systems is telling Wall Street that corporate buyers of products for IT security want to restrict the number of their suppliers, prompting analysts to speculate on which company Cisco might buy next to gain market share.

"The analysis of Cisco suggests that the average large company has security vendors 54-plus, with Chief Information Officer deeming a landscape extremely difficult and complicated to manage," said UBS analyst Amitabh Passi in a research report. "We do not believe Cisco has some delusions of substitution of more than 50 suppliers with only himself, but the goal is to simplify the landscape."

Increase the market share of Cisco in the enterprise security infrastructure $ 25 billion from 9% to 20% -30% is a target of incoming CEO Chuck Robbins, he says Passi.Many large technology companies and defense are jumping more deep in the security market against race leader of the game, like Check Point Software Technologies, Symantec, Fortinet and Palo Alto Networks.

Tim Long, an analyst at BMO Capital Markets, recently met with top corporate executives of Cisco security.

"Cisco believes that one of the major changes that occur in the sector in the coming years is that customers can always switch providers points that provide niche solutions for companies that can provide an architectural approach," Long wrote in a report Monday. "Cisco expects that the changes will become necessary, because some customers currently working with as many 100 different security providers in a single organization.

"This should also drive greater consolidation in the industry." Steps doubts that Cisco would buy a large security vendor like Palo Alto or Check Point, despite its $ 2.7 billion acquisition of Sourcefire in 2013. He predicts smaller offerings, such as $ 635 million deal for Cisco OpenDNS, announced on 30 June.

"We expect both organic investment and M & A play a role in the acceleration of sales and market share growth," said Hand. "The fastest growing sub-segments in the security sector in which Cisco has limited to no presence, and are therefore areas of interest, with identity and access management, Siem, data loss prevention ,. And test application security" Cisco Systems stock was a fraction, near 28, in midday trading in the stock market today.

Cisco is on an Acquisition Roll and it Just Bought One of its Vendors for $139 Million


Cisco announced Tuesday it is acquiring California-based Net Maintenance, Carlsbad, for $ 139 million.That sum includes cash for the company and "retention-based incentives" for executives, Debbie Dunnam, Cisco senior vice president of Success Global Customer, said in a blog.Cisco has been a customer of MaintenanceNet since 2009, says Dunnam. MaintenanceNet makes software that allows manufacturers to easily keep track of customer warranty and service agreements.

Your software does things like automatically send renewal notices to discover that customers bought items that are not covered by their service plans, and so on. It's claim to fame is that it not only works to the manufacturer of the products, like Cisco, but may be used by distributors manufacturer partners. Cisco has a gazillion of them.

MaintenanceNet be added to the overall success of the client (GCS) organization of Cisco, Cisco by utilizing MaintenanceNet. Is the founder of CEO Scott Herron said in a blog that Cisco will not formwork service for its own internal use. It will continue to support customers. MaintenanceNet clients include Panasonic, CDW, Ingram Micro. Lenovo, many others.

Net maintenance was not exactly a start. It was founded in 2004 and clicks over a decade without taking VC money. In 2014, he raised $ 12 million Kayne Partners.This is Cisco's second acquisition in as many weeks. Last week, Cisco bought another software company OpenDNS, or $ 635 million.

A couple of years ago, the outgoing CEO of Cisco, John Chambers, Cisco made waves when he said he would not buy more US companies until the country changed the tax code that allows you to use Cisco stock of cash abroad to pay for them, paying little-to-no taxes on that money. US companies are not taxed in cash abroad until they want to spend on things like home purchases or dividends, then pay the full corporate rate of 35%. Chambers has been an outspoken critic of that tax policy.

Cameras never carried out the threat, breaking that year to spend $ 2.7 billion security company Sourcefire purchase. But Cisco is still buying a lot of companies abroad for a while.That seems to have gone out the window from 2015. So far this year, Cisco has bought five companies, all software companies (one Cisco area where you really need the expertise of homegrown), especially in the US

Default SSH Key Found in Many Cisco Security Appliances

Many Cisco security devices contain default SSH authorized keys that can allow an attacker to connect to device and take almost any action you choose. The company said all of its Virtual Appliance Web Security, Email Security Appliances virtual, content management and security virtual appliances are affected by the vulnerability.



This error is almost as bad as they come on business. An attacker who is able to discover the default SSH key would have virtually free reign of vulnerable boxes, which, given Cisco's market share and presence of the company around the world, it is likely that a high number . Apparently the default key inserted in the software support for reasons.

"Vulnerability in Remote Support feature WSAV Cisco, Cisco Esau Software and Cisco AVMS could allow a remote, unauthenticated attacker to connect to the affected system with root privileges," says Cisco advisor.

"The vulnerability is due to the presence of an authorized default SSH key that is shared by all institutions WSAV, Esau and AVMS. An attacker could exploit the vulnerability by getting the private SSH key and use it to connect any WSAV Esau or AVMS. An exploit could allow the attacker to access the system with root privileges. "

Security researchers say the Cisco failure is unfortunately not unique, and that is an example of a larger problem in the industry."Like most providers recognize that the administration telnet firmware base distance is a bad idea, management consoles Secure Shell (SSH) based increasingly common.

Unfortunately, sometimes these sellers sent by mistake SSH default keyboard across a full range of products.Much better than telnet, everything you need for an attacker to compromise these devices is to get hold of one of them (or Internet firmware mirror), remove the key, and then go to town, "said Tod Beardsley, the Rapid7 security engineering director.


"As we move through these devices, it is recommended that providers place a procedure for 'first start' that dynamically generates a unique SSH key to the device. In this way, the keys are different by the client and not shared among all clients and the one who gets the rest awaiting the key. Note that usually, these devices have no open ports to the administration of the Internet, so that perpetrators usually need to be on the network Local (physical or over a VPN that also has access to Cisco gear in question).

"There are several Metasploit modules available for vulnerabilities like from a variety of suppliers, because once you have the key, the Metasploit module is dead easy to write."
Beardsley said Rapid7 is building a key store SSH known bad and expect to see key Cisco there soon.THE VULNERABILITY An attacker would essentially undetected access to a target system and operate Cisco said the error is simple, especially if an attacker has a man-in-the-middle position in a destination network.

"Exploitation of this vulnerability in Cisco AVMS is possible in all cases where AVMS is used to manage safely the contents of the device. Successful exploitation of this vulnerability in Cisco AVMS it allows an attacker to decrypt communication AVMS, AVMS usurp the identity, and send the modified data to a configured device content. An attacker can exploit this vulnerability on a communication link for any content security apparatus never administered any AVMS "says the notice.

Cisco says there is no solution for the vulnerability, but has published patches for all affected versions of software. The company said the vulnerability has been discovered during testing of internal security. Vulnerable devices offer a variety of safety features, including content, e-mail and Web security.

She also talked about how art helped her weekly "digital detox" and get some perspective on your work if necessary, at a time when he was working seven days a week without interruption. In this way, by what art it is like exercise or other recreational activities: You may not feel you have time to do, but it really helps.

"If you take that time off and come back, you move efficiently," Guerrero said. "What you can not think about work - art, running, unstructured time makes you a better person," he said Guerrero spoke on stage at the conference Tech Bloomberg today. in a speech entitled "The Art and Science of the Code."

Guerrero has been at Cisco since 2008. In recent years has been working in procurement, and distinguished Cisco acquires Meraki and stresses in particular that Sourcefire.

"It's time for the industry to do something different," he said. "For me, I want to go do something very different."

OpenStack Consolidation Is (Almost) Complete-Cisco Buys PistonCloud, IBM Buys BlueBox


And there we go, two of the last men standing, finally falling. Today's news that IBM is acquiring OpenStack Blue Box supplier, while Cisco is buying Piston Cloud.

These deals come just weeks after another provider OpenStack, nebula, folded, and a few months after a major round of bidding in space with Cisco and EMC CloudScaling purchase Metacloud purchase. Alongside these deals, EMC also purchased HP bought Virtustream and Eucalyptus.
With these two agreements, we have almost reached the end of the long predicted consolidation OpenStack.

Mirantis, the high-flying seller OpenStack pure-play remains independent, and probably led to an IPO Meanwhile smaller players, such as the Australian Aptira respected provider continues to shine.
But the biggest names in US OpenStack vendors, this marks the end of pretty independent. So this little trip was a success or a failure?

It's a little hard to say because the terms of today`s not been announced, but most people suspect Piston Cloud approached the corporate death. That, coupled with the fact that Cisco already has a lot of things going on OpenStack indicate that, if the agreement was PistonCloud acquihire more than anything else. Cisco also announced last year over the delivery of Intercloud, a worldwide network of partners with OpenStack clouds driven engines.

Blue Box is perhaps a little more interesting. IBM, of course, buy SoftLayer a couple of years ago and also has its own history OpenStack happening. In recent Magic Quadrant for cloud providers, there was little love given the success of IBM in space, perhaps BlueBox will help with that.

When Blue Box sits in all this is a bit hard to say. Blue Box adds you an OpenStack offering managed remotely to the portfolio of IBM and, given the small amount of money the company had been raised to date, maybe the deal was a no-brainer for IBM (and allows the team Blue Box to get some breathing space).

Having seen OpenStack from day one, it's a little sad to see the end of all these independent companies - a certain vitality could only have gone now. But perhaps it is also a sign of a maturing project and a safe landing for everyone involved.
