Tech Bytes: DDOS and State Exhaustion With NETSCOUT – Updated

Its not widely that DDOS attacks also cause damage from state exhaustion in devices. A recent study why Netscout surprised me that many engineers are aware of overload bandwidth or routing devices but give less considerations to state exhaustion in application aware devices.

Musing: Does 802.1x Matter Anymore ?

802.1X has little relevance over time.  As distributed work becomes widespread, laptops and smartphones will not connect to campus or branch networks operated by IT departments. Home broadband, cafes, kids schools, 4G/5g etc. Each user device will have some software mechanism/agent/method to access resources in SaaS, on/off prem DC/cloud and on son There is a market […]

Tech Bytes: DDOS and State Exhaustion With Netscout Arbor

Its not widely that DDOS attacks also cause damage from state exhaustion in devices. A recent study why Netscout surprised me that many engineers are aware of overload bandwidth or routing devices but give less considerations to state exhaustion in application aware devices. 

Firewalls, IPS and reverse proxies are subject to overload failure when the internal state is exceeded. This includes server side caches (Varnish, memcache etc) and all this elements should be part of your DDOS strategy. 

Roland Dobbins talks about the nature of these attacks and how to implement stateful protection while using stateless DDOS technology.

Network Break 346: Extreme Gets SDWAN, Huawei Struggles and SpaceX Swarms

The world of virtual donuts is supply constrained. Extreme Networks finally gets SDWAN buying Ipanema from Infovista at a bargain price. Research firms that does the numbers Dell'oro pitches that Education and Government markets will be spending big on WiFi6E - we aren't so sure that campus spending will be big just some spending but Dell'oro told us that government economic stimulus is the driver. Most will focus on distributed work.

Huawei posted 29% revenue reduction as the trade sanctions impact their overall business. A reminder that political solutions are slow if you have to make plans. And in space networking, SpaceX acquires pico-satellite company Swarm for IOT networking.
