The new Kemp Flowmon ADS 11.3 enhances your contextual understanding with built-in knowledge of adversary tactics and techniques described in the MITRE ATT&CK framework.

Today’s networks have evolved a long way since their early days and have become rather complicated systems that comprise numerous different network devices, protocols, and applications. Consequently, it is practically impossible to have a complete overview of what is happening in the network or whether everything in the network works as it should. Eventually, network problems will arise.

I’ve been updating some of our security documentation explaining what we do to ensure our product is suitable for the security models in regulated industries, such as finance and healthcare. Talking to our security guys, I was flabbergasted to find out that there are monitoring products out there that go against what is not only an industry best practice but also the right thing to do: agents that open and listen on fixed TCP ports!

In a network operations center (NOC), alerts originating from hundreds of servers, application monitoring systems, emails and ticketing services compete to catch a NOC analyst’s attention. NOCs face many challenges in parsing through alerts to identify actionable notifications and mobilize the right response team into action.

HAProxy 2.4 adds exciting features such as support for HTTP/2 WebSockets, authorization and routing of MQTT and FIX (Financial Information Exchange) protocol messages, DNS resolution over TCP, server timeouts that you can change on the fly, dynamic SSL certificate storage for client certificates sent to backend servers, and an improved cache; it adds a built-in OpenTracing integration, new Prometheus metrics, and circuit breaking improvements.

The question I am regularly asked is, “What use is OTN, when services are all IP, and routers handle connectivity directly across optical fiber connections, or wavelengths on optical fiber (IPoWDM)?”

In today’s technology-driven world, network automation tools have evolved from convenience to necessity in practically every IT field. Traditionally, IT managers would issue manual command lines to manage networks, but given the size of today’s business networks, manual workflows dealing with repetitive network tasks have become time-consuming and counterproductive, often at risk of incurring errors from manual implementation.

First, thanks for indulging the clickbait title joke. Serialization is the unsung hero of harmonizing network and application relations and deserves the occasional, snarky callout. Moreover, identifying how the unique mix of network clients in your environment consume your carefully manicured infrastructure is critical for managing network cost. Because today, a rapidly expanding, diverse pile of new technologies all assume the network is a magic grid, no tuning required.

There are few areas of networking so problematic, and at the same time so fixable, as network congestion. Understanding the common causes network congestion causes can help you detect them, fix them, and keep them from cropping up again. Network congestion is generally seen by the end-user as “network slow down”, or response times on our computer not being up to par.
