VMware Evolve Transform Security is Coming to A City Near You!

Modern IT professionals face significant security challenges. As digital transformation continues to connect applications, users, and data in the cloud, perimeter security models that once offered businesses protection are no longer sufficient. Critical visibility into users and endpoints is missing, enforcing policies is difficult, and, in the meantime, cyberattacks are more sophisticated and costly than ever.

What do IT teams need to defend today’s applications, users, and data from potentially brand-damaging attacks?

That’s the question VMware experts will be tackling during our VMware EVOLVE Transform Security events, coming to a city near you. During these half-day, in-person events, you will learn how a ubiquitous software layer can help support the security challenges of the modern business. 

VMware experts will guide you through how to:

  • Secure application infrastructure and better align security controls to apps
  • Secure identity and endpoints to control access and enforce data loss prevention
  • Streamline governance, risk management and compliance to limit cyber-attack vectors

Reserve your spot at an upcoming Transform Security-focused VMware EVOLVE event in your city:

A kindly lesson for you non-techies about encryption

The following tweets need to be debunked:



The answer to John Schindler's question is:
every expert in cryptography doesn't know this
Oh, sure, you can find fringe wacko who also knows crypto that agrees with you but all the sane members of the security community will not.


Telegram is not trustworthy because it's closed-source. We can't see how it works. We don't know if they've made accidental mistakes that can be hacked. We don't know if they've been bribed by the NSA or Russia to put backdoors in their program. In contrast, PGP and Signal are open-source. We can read exactly what the software does. Indeed, thousands of people have been reviewing their software looking for mistakes and backdoors.

Encryption works. Neither the NSA nor the Russians can break properly encrypted content. There's no such thing as "military grade" encryption that is better than consumer grade. There's only encryption that nobody can hack vs. encryption that your neighbor's teenage kid can easily hack. There's essentially nothing in between. Those scenes in TV/movies about breaking encryption is as realistic as sound in space: good for dramatic presentation, but not how things work in the real world.

In particular, end-to-end encryption works. Continue reading

Security Here I Come!

The announcement has been made!  It is completely official!  I can finally share the awesome great news I am so excited about.  Security will be my absolute #1 focus now. 

Security has always fascinated me.  My entire career.  ….. It’s just that the fundamentals of routing and design intrigued me even more.  🙂

But now?  Yeah baby!  Now I get to flip a switch… dive into and completely surround myself with all things Security.  And I just could not be any more tickled pink and excited.  I feel like all my years of networking have been a build up towards this.

Am I leaving my CPOC lab and job I adore so much?  Nah… I’d go through withdrawal.  LOL.  Nah… wouldn’t be pretty.  It is just my role that will be changing.

Woot woot!  Security here I come!  ROCK!

 

 

 

 

Technology Short Take #84

Welcome to Technology Short Take #84! This episode is a bit late (sorry about that!), but I figured better late than never, right? OK, bring on the links!

Networking

  • When I joined the NSX team in early 2013, a big topic at that time was overlay protocols (VXLAN, STT, etc.). Since then, that topic has mostly faded, though it still does come up from time to time. In particular, the move toward Geneve has prompted that discussion again, and Russell Bryant tackles the discussion in this post.
  • Sjors Robroek describes his nested NSX-T lab that also includes some virtualized network equipment (virtualized Arista switches). Nice!
  • Colin Lynch shares some details on his journey with VMware NSX (so far).
  • I wouldn’t take this information as gospel, but here’s a breakdown of some of the IPv6 support available in VMware NSX.

Servers/Hardware

  • Here’s an interesting article on the role that virtualization is playing in the network functions virtualization (NFV) space now that ARM hardware is growing increasingly powerful. This is a space that’s going to see some pretty major changes over the next few years, in my humble opinion.

Notes on open-sourcing abandoned code

Some people want a law that compels companies to release their source code for "abandoned software", in the name of cybersecurity, so that customers who bought it can continue to patch bugs long after the seller has stopped supporting the product. This is a bad policy, for a number of reasons.


Code is Speech

First of all, code is speech. That was the argument why Phil Zimmerman could print the source code to PGP in a book, ship it overseas, and then have somebody scan the code back into a computer. Compelled speech is a violation of free speech. That was one of the arguments in the Apple vs. FBI case, where the FBI demanded that Apple write code for them, compelling speech.

Compelling the opening of previously closed source is compelled speech. Sure, demanding new products come with source would be one thing, but going backwards demanding source for products sold before 2017 is quite another thing.

For most people, "rights" are something that only their own side deserves. Whether something deserves the protection of "free speech" depends upon whether the speaker is "us" or the speaker is "them". If it's "them", then you'll find all sorts of reasons Continue reading

CCIE/CCDE Re-certification: An Opportunity to Learn and Grow

I did not pass my CCDE re-certification last week.  Why write a blog about a “failure”?  Honestly?  Because I think we as an IT industry overly focus and give too many kudos to the passing only.  Not to the hours and hours of studying and learning… not to the lessons learned… not to the growth gained from the studying journey.  Just to the “pass/fail”.  Well damn… no wonder people cheat.  Their focus isn’t on the learning or the journey.  Just the passing.

I thoroughly believe the expression –

Sometimes you win….. Sometimes you learn.

Did I want to pass last week?  ROFL!  Are you kidding?  Of course I did!  Did I “deserve” to pass?  Well…. um…. err… not exactly.

See that 10% at the bottom of the “Written Exam Topics v2.1?”   Truth be told I didn’t quite exactly study that part very much.

So what is my plan now?

LEARN

Honestly in my job I am not doing much Cloud, SDN, or IoT.  AND I have to admit I am quite happy I am now essentially forced to learn these to a Continue reading
