How To Improve Network Security and Performance (by Keith Bromley)

How To Improve Network Security and Performance 

As you may have seen, I like to talk a lot about network visibility – what it is and what the benefits are. Therefore, I often get the question, “So, how can I specifically use network visibility to solve my problems?” – sort of a Jerry Maguire “show me the money” type of question. The short answer is that there are lots of use cases available, it simply depends upon what your individual needs are. Let me show you.

Hopefully you have heard of the term “network visibility” by now. It has become commonplace over the last year or so. If not, network visibility is simply the ability to see what your network is doing and how it is performing. You can get a longer narrative of the definition here and free resources on network visibility are available here. While some might think that network visibility is a non-issue these days. It’s actually not. Many networks have had, and continue to have, network problems such as:  downtime, slow running applications, missing data, expensive troubleshooting activities, and security breaches.

The first half of the solution to this problem is straight forward. You should consider implementing a visibility architecture. This approach allows you to integrate your network architecture with your security architecture so that you can capture all of the data that you need. The right data is crucial to minimizing (and even preventing) downtime, repairing the network as fast as possible, meeting and exceeding your internal and external customer SLAs, and maximizing your network security.

The second half of the solution is to implement the right technology and processes to solve your problems. Basically, what can you, and what should you, implement? Let’s look at this subject in further detail.

First, you need to figure out what your specific trouble areas and blind spots are. You may already know about several of your problem areas. At the same time, you probably do not know what you do not know. So, there may be some hidden problems as well. These areas, called blind spots, are where you can’t tell (or don’t know about) that there is an issue. There are numerous sources for blind spots including:  the use of cloud networks, silo IT, rogue IT, mergers and acquisition with different networks and applications, etc. You can get more details on blind spots in this article .

Once you figure out what your problems areas are, take a look at this free resource. This resource examines 6 different categories of solutions that resolve different types of known problem areas and/or blind spots. These areas include:

  • Network security improvements
  • Cost containment capabilities
  • Enhanced troubleshooting efforts and network reliability
  • Removal of network blind spots
  • Optimization of Network Performance
  • Strengthening of regulatory compliance initiatives

In fact, the book contains 68 different examples of what you can do (i.e. use cases), broken down by those six categories. Some examples are:

  • How to expose indicators of compromise
  • How to make inline security tool deployments more reliable by using High Availability
  • How to reduce/eliminate the need for Change Board Approvals and crash carts
  • How to use application intelligence to conduct proactive troubleshooting
  • How to simplify inline SSL decryption by using an NPB with integrated decryption
  • And many others

Once you read the book, you will have a very good of what you should do and how to go about improving network operations. It shows you how to combine taps, bypass switches, network packet brokers, application intelligence, and security and monitoring tools to achieve your security and monitoring goals.

LMTV LIVE | How to Create Scalable Visibility in your Data Center (with Chris Bihary of Garland Technology)



YouTube LIVE event start time: Wednesday, July 19, 2017, 9:30 AM PST


Garland170x200How do you scale your network infrastructure to support multiple monitoring tools - while ensuring 100% packet capture?

This is the problem we have been hearing in the last few years. Data centers (D1 & D2) and enterprise networks have many challenges and two of the big ones are providing the IT department anytime access to full-duplex traffic, while guaranteeing full packet capture. Now layer on top of that a stack of 1G legacy monitoring tools in addition to the migration to 10G/40G and 100G speeds.

Join us for to learn about the latest visibility solution from Garland Technology’s as they introduce and demonstrate their Passive Fiber Modular Chassis System, a flexible, scalable and affordable high density solution for managing up to 24 links in a 1U box at network speeds of 1G/10G/40G/100G.

LMTV LIVE | Visibility Architectures - Understanding Security Solutions (with Keith Bromley of IXIA and John Jacobs of Fortinet)



Yx_X0tC2Security is top of mind for most IT departments. Once the subject comes up, everyone has their own ideas about what security tools (IPS, IDS, DLP, WAF, etc.) and what defense strategies (black list, white list, defense in depth, etc.) should be put in place. But what about the functionality that enables the security solutions? How do you create the visibility into the network that you need to create a truly adequate security solution? Join us for the final podcast in this Best Practice series to learn about what a visibility architecture is and how you can use it to create your inline and out-of-band network security solutions.

LMTV LIVE | What Can I Really Do With A Visibility Architecture? (with Keith Bromley of IXIA and Mike Canney of IXIA)



Yx_X0tC2Network visibility is an often overlooked but critically important activity for IT. The real question people often ask is, what can I really do with a “Visibility Architecture?” The short answer is that it enables you to quickly isolate security threats and resolve performance issues. The long answer is that there are over 50 different monitoring and visibility use cases that are either enabled and/or improved by implementing a Visibility Architecture. This is our second of several discussions to learn what a visibility architecture is and how it can help you optimize network data capture and analysis.

LMTV LIVE | Visibility Architectures - Best Practices for Network Monitoring (with Keith Bromley and Recep Ozdag of IXIA)



YouTube Live Event starts at 9:30AM PST, Wednesday, March 22, 2017


Yx_X0tC2This week we will be speaking with Keith Bromley and Recep Ozdag, Senior Manager of Solutions Marketing and VP of Product Management of IXIA, respectively.

Network visibility is an often overlooked but critically important activity for IT. Visibility is what enables you to quickly isolate security threats and resolve performance issues; ultimately ensuring the best possible end-user experience. A proper visibility architecture addresses the strategic end-to-end monitoring goals of the network, whether they are physical, virtual, out-of-band, or inline security visibility.

Join us for the first of several discussions to learn what a visibility architecture is and how it can help you optimize network data capture and analysis.
