@TalosSecurity There's a crazy amount of F/OSS security tools from across the Cisco empire, here's the combined output of us and the Neohapsis teams: github.com/CiscoCXSecurity - @duosec folks, what you got?

Did you know that Talos has 27 open-source tools available for anyone to use? This overview of all our free offerings — from decryptors to anti-virus engines — will tell you how to use these tools to improve your security resilience cs.co/6010O77pa

@jonathandavidsn @RajnChop @_TomGillis @Cisco Yeah, people do that with Google Slides pretty much all the time, same with Office 365. What am I missing?

While we were waiting to board the plane at SFO, @RajnChop worked on a slide deck. When we say we can work from anywhere, we mean it #HybridWork #WeAreCisco @_TomGillis @Cisco

@wandynamics @bitsinflight We’re considering this as a viable alternative. Consistent OS across our Datacentres, metro, buildings, and branches would be invaluable.
English
If you have any Cisco ASR or ISR routers that are going EoL or EoS this year, might we suggest an alternative? WAN Dynamics works with Arista for WAN Routing System bit.ly/3Av15aW

@danieldibswe That’s how we build our data center switch configurations - no CLI touch at all for any operations now. We will be doing the same in our branches starting this year, early next. All variables come from systems of record.
English
@danieldibswe We used to call those the Silvano Gai Tags internally when he was proposing them in the early 2000s
English
Sometimes huge news are hidden away in the release notes. As of IOS-XE 17.11, Catalyst 9300 supports SGTs with VXLAN/EVPN. Why is this important? Previously the only fabric supporting SGTs was SDA with LISP. Interesting to see what this means for DNAC cisco.com/c/en/us/td/doc…

@dscheinm Or creatively rewrite history to suit their narrative: “the company never sold anything til I was here” “I launched the company in 20XX” or changes the name of the company or something to allow for that story to take root.
English
The most dangerous non-founder CEO’s are the ones who confabulate that they are indeed the founder/savior of the company.
English
@danieldibswe @ioshints It fails at simple math, stop the hype machine.
English
As always, @ioshints has a balanced opinion on ChatGPT. It can do some cool things, assuming that there is data that it can read, but it does not in any way or form replace a human in IT. Only a small part of the job is configuring things.

@etherealmind My favorite is a friend works at a company that did a press release that they went ‘all in on cloud’ and moved ‘everything to the cloud’
The put all their servers in a hosted DC. Smh
English
When cloud repatriation happens, does anyone notice ? The sound of one hand clapping ? A tree falling in the forest ?
EtherealMind@etherealmind
There is no marketing spend when moving an enterprise workload to on-prem cloud. No press releases, no analyst briefings, no PR pitches. That’s why you don’t hear about it. It just happens and the work gets done.
English
@Kangaruess What an abomination. I remember when the CatOS team was explaining this in the mid 90s and we were incredulous. Was literally a ticking time bomb.
English
Can we please get a moment of silence for the greatest protocol of all time being removed from the announced CCIE v1.1 Exam blueprint update🥲 #vtp #longlivevtp #ccie #exam #lab #labeveryday #study #cisco #rip #changes #blueprint

@Bahlkris We had several like that as well. GIS then started making us upgrade software because of known vulnerabilities. We were upgrading Cisco kit every other weekend…. Could never get compliant
English
@rugsharkd @sama But you can mandate that all banks not compliant with Dodd Frank post it on the front page of their website, and at each branch. Then hold the execs responsible.
English
@NetworkRalf @sama You can’t buy insurance for an accident after the accident has already happened
English
ugh fine here is my SVB thread:
TL;DR: at this point, to be certain of avoiding catastrophe, the FDIC needs to temporarily guarantee all deposits. other solutions might work, but this is the best one.
English
@danieldibswe We use @AristaNetworks in our low latency trade plant. Most exchanges and everyone else in there seems to as well. There are good reasons.
English
Anyone with experience in low latency networking that has some advice for Ivan?
Ivan Ivanov@IvanIva29134106
@danieldibswe @ioshints @davidbombal Can you recommend a good starting materials for low latency networking?? Are there any good books or trainings for a CCIE to deep dive in low latency networking??
English
@danieldibswe We banned stacks - much easier and obvious failure characteristics. Fibre plant was a sunk cost but we pulled 48pair from each IDF to each of the MDFs
English
When deploying a switch stack, do you consider where you put your uplinks? I recall some documents saying to avoid active switch and standby switch, if possible. The logic being that if the active switch fails, you don't lose any uplinks.
Is active most likely to fail?
English
@rugsharkd @sama Done right the bank pays for insurance. If the FDIC does a bailout for this type of circumstance the Officers of the bank should be liquidated, bonuses clawed back from execs, and the directors and officers criminally charged.
The bonus and equity clawback pays off the FDIC.
English
@sama And where should FDIC get the money to cover the deposits? Should the ensure every banks total deposits? What return does the tax payer get by providing this insurance for free?
English
also, i was once on the board of a bank holding company.
the fault here lies with the management of SVB, but there were intense and frequent audits by regulators to prevent exactly this from happening.
English
@GRDecter Really depends if they have a 10b51 or not. Most execs have predetermined selling plans on vesting or at specific price targets.
English
Silicon Valley Bank CEO, CFO and CMO sold +$4.4MM in stock over the last 2 weeks.
But they didn’t know anything right?

@grapegrower1986 @RepSwalwell Dodd Frank was a set of regulatory controls out in place because of the crash of the banks and housing market in 2008.
English
@RepSwalwell Dodd/Frank helped crash the housing market, thanks…

Millions of middle class paychecks are at risk this next payday because Trump and McCarthy deregulated banks. And he bragged about it.
MeidasTouch@MeidasTouch
Whoa! Here it is. The moment in 2018 when Donald Trump removed the Dodd-Frank regulations that would have prevented the Silicon Valley Bank collapse. Don’t let anyone forget this.

@John_Capobianco What’s the error rate? I can’t get reliable results out of ChatGPT, it lies with absolute authority. Can’t have that on a critical network.
