State Of The Network: Analyst Jim Frey’s View/ Q&A

JDSU’s Network Instruments business released its seventh annual “State of the Network Global Study.” Of the findings – after polling 241 network professionals – a provoking theme emerged: 80 percent of respondents viewed software defined networks (SDN) as unimportant or were just going to “ride out the hype” – saying it is “Like a Road Trip Without a Map.”

frey2A leading authority in the enterprise network management space with a lot of experience covering this sector is Jim Frey, vice president at Enterprise Management Associated (EMA), which conducts IT & data management research, industry analysis and consulting.

Inspired by the recent study, I reached out to Jim – who has briefed regularly with the Network Instruments team – for his take on the state of network today as he sees it, and his view of where the market is headed.

Q: Jim, what do you feel are the top priorities – opportunities and/or challenges – for the enterprise sector at a time when SDN and Big Data are all the rage?

Looking at where SDN is in its maturation, the timing is still very early and it is not having a big impact yet. Big data – the collection, analysis and sharing of data by network management systems – is rapidly growing in importance as a company asset. Here is what I see as top priorities and megatrends as SDN and big data emerge within larger enterprises.

First, cloud and virtualization adoption rates are very high and topics to keep an eye on. The cloud is enabled by virtualization and that dynamic creates added challenges for performance monitoring. The ability to understand how services perform when deployed in the cloud, especially from an end-user perspective, makes visibility a critical – and challenging – aspect of effective resource monitoring and management.

In addition, making sense of the large amounts of network monitoring data and what can be done with it are key. In particular, we see network teams taking a more proactive approach to handle performance challenges as they find hidden trends and relationships between application and infrastructure performance using the latest big data analysis techniques.

Lastly, I’d say another big trend taking hold is the continuous market transition between separate siloes or functional areas in IT operations, moving towards more converged operations and IT organizations. This has some direct impact on choices of network management tools and how they get used over time.

Q: The “State of the Network” study spotlighted that a fair amount of network managers and engineers agree that SDN is a “Road Trip Without a Map”? Were you surprised to see that finding?

This is very consistent with the conclusion that I have had in my own research. I’ve found that only 20 percent have taken part in any degree of SDN deployments. And, less than 10 percent are in full deployment. The remaining are at the early stages of research, testing, or evaluation with many network managers still trying to figure out where and how to use it. They are asking: “Is there enough pain in my current network to warrant an alternative like SDN?” Most organizations – most mainstream enterprises – would answer, “No, not enough to warrant embracing these relatively immature technologies at this time.”

Important to note is the fact that there are two main types of SDN. One type is the overlay network, which is purely software/virtual; the other is OpenFlow-based, which we call an underlay SDN. Of the two, the virtual overlay is a more natural extension of existing virtual networks, as it uses tunneling and the existing network, so no new physical infrastructure is required. However, because it is typically managed by system administrators with little input from the network team, there are two areas of potential challenges. The first is to address network capacity planning and the second to ensure visibility into the encapsulated, tunneled traffic for satisfactory service delivery monitoring.

Q: A big takeaway seems to be that now more than ever service providers and enterprises must be equipped with technology that provides key visibility and troubleshooting. How important are these capabilities for enterprise and service providers to deliver quality services, build reliable networks?

Absolutely – as you can tell from prior answers, visibility has never been more important. In the current environment there are more layers of technology, more dynamic aspects that come with virtualization, and with that, the more you must understand what’s going on and be able to piece together the full story. For example, how is that app being delivered? From where it’s being hosted to the consumer, what’s happening along the way to make it work? And, how is the quality and efficiency, what is experience of the consumer or end user?

The picture is getting a whole lot more complex – all of the trends we have addressed – virtualization, SDN, big data, cloud…they all drive a heightened need for deep and accurate visibility.

Videotron Aims To Be Fourth National Cellco

Pierre Dion, CEO of Quebecor, the parent group of Quebec-based cable and cellular network operator Videotron, this week gave a clear message that his company intends to utilise its recently-won 700MHz spectrum to roll out a 4G network in provinces across Canada whilst aiming for consolidation with rival operators to create the fourth national rival to Rogers, Bell and Telus. CBC News quotes Dion’s speech at the Canadian Telecom Summit, in which he declared: ‘Our vision is to provide Canadians with a new high quality, low-cost wireless choice and real wireless competition … Under the right conditions, we are ready, willing and able to become Canada’s fourth wireless competitor.’ The statement of intent follows a speech from rival Wind Mobile’s CEO Anthony Lacavera, which as reported by CommsUpdate, made it clear that Wind is looking for a merger deal, while financially stricken Mobilicity is another target for consolidation.

Wind Still Has Plenty Of Gas, Puffs Lacavera

Wind Mobile’s CEO Anthony Lacavera gave a speech yesterday at the Canadian Telecom Summit in Toronto laying out his company’s current position, in which he stressed that the crucial factor in enabling the mid-sized
Canadian cellco to grow will be access to more mobile spectrum for rolling out 4G LTE services – potentially by acquiring frequencies owned by rivals. As reported by Bloomberg, Lacavera said that a merger with financially stricken Mobilicity or another spectrum holder remains desirable in order to compete better with Canada’s three nationwide mobile operators Rogers, Telus and Bell, after Wind was unable to participate in the country’s latest licence auction due to main shareholder Vimpelcom withholding any new significant investment. Meanwhile, the Russian-backed parent group continues to consider its options for its Canadian subsidiary, where it has been blocked from taking voting control by a government decision.

Combining Wind with Mobilicity or ‘other new entrant spectrum’ would be of a significant benefit to both merged parties, Lacavera’s speech noted, while admitting that ‘the challenge we at Wind face is securing any one of these sources of spectrum at terms and value levels that the business of Wind can support, and within the timeframe that the spectrum is needed to meet LTE demand.’ Although Mobilicity’s assets could potentially be snapped up at a discount in bankruptcy proceedings, the court process presents obstacles, the Wind CEO observed previously. Despite the challenges faced, Lacavera has scotched claims that Wind is in danger of folding, calling such reports ‘categorically false,’ and his speech yesterday forecast that the company will turn EBITDA profitable in 2015 on the back of its continuing upturn in both revenues and subscriber numbers. He added that Wind had 735,000 subscribers at the beginning of June after adding 21,000 net new users (including 14,000 post-paid) in May (up from a total of 702,000 subscribers at end-March 2014 and 676,000 at end-December 2013, TeleGeography adds). In a previous interview Lacavera stated Wind needs to find funding of CAD400 million to CAD500 million (USD370 million to USD460 million) to build an LTE network, which would take around two years to complete – while it needs to do this in the next three to four years to compete effectively with Rogers, Bell and Telus, i.e. it must secure the necessary funding and spectrum within two years. In further comments from the Telecom Summit speech quoted by Reuters, the Wind executive declared: ‘I am confident our operating results and the positive momentum of the business will enable us to access the capital markets.’

Network ‘Security Cameras’ Offer Insight after Attacks

2014-jun-banner Security is a top concern for anyone running a network today. The recent Heartbleed bug and other high-profile hacks have shined a new light on the fact that security strategies in the enterprise must constantly evolve to meet the challenges of new and ever-changing attacks.

In the spring of 2014 news of the Heartbleed bug hit the wire sending the tech world scrambling to patch the now notorious OpenSSL vulnerability that allowed individuals to steal private information like certificate keys, passwords, and other content commonly used to breach systems or impersonate users.

“Heartbleed is a programming bug in the 1.0.1 through 1.0.1f versions of OpenSSL,” says EMA Director of Security and Risk Research, David Monahan on the specific versions affected by the vulnerability. “The only means of identifying if the bug is exploited would be doing network sniffing from a network analyzer perspective while the attack was taking place, or with a retrospective analysis tool.”

Network tools with back-in-time analysis like Network Instruments’ GigaStor are designed to watch the network, analyze conversations, identify issues, and alert administrators to problem scenarios. These features make them an excellent tool to help identify and isolate unauthorized activity. In addition to the regular assortment of firewalls and other defensive security measures, network forensic tools like these can be used after an event to identify both known and unknown attacks, speeding the cleanup process.

“You can get a lot more detail if you have the entire packet stream,” says Monahan. “In a case like Heartbleed, you get the details on what was sent back in the communication between the client and your server. You can say, ‘Yes, we were attacked,’ and review the communications exchange to see what data was returned to the attacker. You can determine whether they got passwords or private keys, or any other confidential information, or they just got other areas of information that, in and of itself, are not valuable.”

Solutions like GigaStor provide critical details post-event, allowing the user to reconstruct the entire conversation, view the information compromised, or focus on the content extracted. How did the attacker gain access? What was stolen?

“You need advanced traffic analytics and filtering to identify and correct issues such as Heartbleed,” says Network Instruments Professional Services Manager, Casey Louisiana. “With GigaStor, I was able to rapidly build a filter to detect its signature, set up an alarm to alert on it, and then quickly process terabytes of data to determine if the network had been compromised,” he says, calling attention to the need for tools to contain and solve threats after the security perimeter has been breached.

“Beyond the ability to perform layer two through seven analysis, many users don’t appreciate that GigaStor provides sophisticated packet pattern recognition that is ideal for addressing security threats,” Louisiana says. “GigaStor, like a security camera in a retail store, requires a place to store the data that’s coming in. This is often immense amounts of data for extended periods of time. But it’s the ‘secret sauce’ or ‘magic’ of the advanced analytics and pattern recognition that makes sense of the mass of data.”

Not all tools offer this analytical capability, but it has proven essential in the enterprise where breaches are not immediately detected and the ability to “rewind” back to an attack-in-progress can yield more insight.

“With large enterprises there is so much data that’s coming back,” says Monahan. “It’s impossible for humans to actually process.”

Network Instruments’ GigaStor packet capture appliance offers storage of up to a petabyte of data, and used in conjunction with a network analyzer, plays a significant role for transaction-heavy organizations in data mining, security forensics, and data retention compliance.

“The two most critical points for identifying malware intrusions are to know what’s going on in the network and what’s going on at the end point,” says Monahan. “To obtain the detail for the network level, you really need the packets.”

One of the most potentially damaging aspects of these types of breaches is that many network teams have no idea they are being hacked despite both the number of tools on the market, and the solutions already installed on their networks and not being utilized.

“We need to do a better job of helping our customers see that there’s value in this type of approach,” says Louisiana on GigaStor’s packet capture function and its use in post-event network forensics. “Heartbleed is a recent example, but what’s the next Heartbleed? How do you look for abnormal traffic patterns? It’s about establishing a baseline and knowing that anything happening outside of that is abnormal. Many of our customers are not using our tools in that way.”

“When we need more information, retrospective network packet capture and analysis is one of the ways to do that,” says Monahan. “And it’s a very strong way. There are basically two ways to get something malicious on the network. I can take a USB-type removable media and plug it in, and infect my endpoint or I’m going to get it downloaded across the network. If it just sits on that machine and it never goes anywhere else, is it really a threat? Probably not. At some point it’s going to need to communicate to home base to transfer information or create that bot network. If you have something watching the network, you’re going to catch that. Network analyzers can definitely be a portion of that capability. They will see the communication assuming proper placement. From that point we can see what’s out there, what data it’s trying to move, how often it’s communicating, and determine how malicious it really is.”

An attentive security team, the right network analyzer, and enough storage for effective post-event retrospective analysis are powerful weapons in the constant battle to keep threats off your network. These elements working interdependently can create strong defenses that are higher in value than the sum of their parts. “Having both trained personnel and the right tooling are key,” says Monahan. “You can’t do it with either one alone.”
