Top Five Ways to Optimize Performance Monitoring (by Keith Bromley)

Top Five Ways to Optimize Performance Monitoring

Network performance monitoring, and especially network optimization, is more of an art than a science because there are so many factors that figure into network and application responsiveness. In addition, while there is a plethora of data on the network, determining the right kind of data that you need and where you should you be capturing it from can become very difficult. This data collection process is then further complicated by the fact that tactical data loses up to 70% of its value after 30 minutes. This makes the speed and accuracy of data analysis critical.

The solution to these problems is to create a network visibility architecture. Network visibility is what enables you to quickly isolate and resolve performance issues; ultimately ensuring the best possible end-user experience. From there, you can use anomaly driven data flows to quickly isolate potential problems.

Here is what you need to set up a visibility architecture:

  • Taps, virtual taps, and bypass switches – These devices give you timely access to the data you need
  • Network packet broker (NPB) – This device gives you filtering capability to maximize the flow of relevant information to your monitoring tools. NPBs enable: data aggregation, filtering, deduplication, and load balancing of Layer 2 through 4 (of the OSI model) packet data.
  • Application intelligence functionality (within an NPB) – This functionality provides additional filtering and analysis at the application layer, i.e. Layer 7 of the OSI stack
  • The final layer is made up of your security and monitoring tools. These devices are typically special purpose tools (e.g., sniffer, NPM, APM, etc.) that are designed to analyze specific data.

Top Five Ways to Strengthen a Security Architecture (by Keith Bromley)

Top Five Ways to Strengthen a Security Architecture

 

Network security is one of, if not THE, most important topic for IT professionals. This is true for the security engineer, the CISO, CIO, CLO and even the CEO.

The question though is, “What can you really do to improve it?” The answer is to strengthen your deployment of inline security tools. In terms of regulatory compliance for PCI-DSS and HIPAA, inline security tool deployment may not be critical, but it is imperative for a security architecture where you are trying to maximize your defenses.

Network security 2

Here are five of the top activities IT professionals can implement to improve their company’s inline security architecture:

  1. Insert external bypass switches between the network and security tools to improve network availability and reliability
  2. Deploy threat intelligence gateways at the entrance/exit of your network to reduce false positive security alerts
  3. Offload SSL decryption from existing security devices (like firewalls, WAFs, etc.) to network packet brokers or purpose-built devices to reduce latency and increase the efficiency of your security tools
  4. Perform serial tool chaining for suspect data to improve the data inspection process
  5. Insert network packet brokers to improve security device availability by using either n+1 or high availability technology

LMTV LIVE | Improve Network Security with Visibility (with Keith Bromley and Martin Holste)

 

LIVE Event Start Time: 9:30 AM PST, March 7, 2018

NetworkVis_Ad_TroubleshootIT_170x200Keith Bromley from Keysight Technologies (formerly Ixia) and Martin Holste from FireEye will be talking about how to use network visibility to improve network security.

Network security is one of, if not THE, most important topics for anyone in IT. This is true from the security engineer all the way to the CISO, CIO, and even the CEO. Everyone wants to improve security. The question though is, “What can you really do to improve it?” One solid answer is to strengthen your deployment of inline security tools. This is critical to an architecture where you are trying to maximize your defenses. Network visibility is what enables you to quickly isolate security threats.

Some key thoughts we will discuss during the event:

  • A Visibility Architecture is an end-to-end infrastructure which enables physical and virtual network, application, and security visibility
  • There are several possible ways to optimize your security architecture:
    • Insert external bypass switches between the network and security tools to improve network availability and reliability
    • Deploy the right kind security tools, like an IPS, to inspect incoming data and improve threat detection and isolation
    • Perform serial tool chaining for suspect data to improve the data inspection process Insert network packet brokers to improve security device availability by using either n+1 or High Availability technology
  • Security tools, like those from FireEye, can provide inline capabilities to help you improve your network operations. This lets you see and capture threats before they enter your network.
  • A visibility architecture typically yields immediate benefits such as the following: eliminating blind spots, improving data flow to security tools, and maximizing network and tool availability

Join us for the third of several discussions to learn how to unleash the power of network visibility.

LMTV LIVE | How to Improve Network Troubleshooting (with Keith Bromley and Bill Coon)

With Paul Offord of Advance7 hosting, Keith Bromley from Keysight Technologies (formerly Ixia) and Bill Coon from Riverbed will be talking about how to use network visibility to improve troubleshooting.

According to an Enterprise Management Associates report (Network Management Megatrends 2016), IT teams already spend around 36% of their daily efforts on reactive troubleshooting efforts. In addition, pressure can increase exponentially on IT personnel as problem resolution time increases, since it directly correlates to network and application slowness and downtime. There is a new LMTV event happening on February 21, 2018.

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.
