Microsoft AZ-500 down, more to go

Another month, another Azure cert! 🙂

So, for the last couple of weeks, I was reading about, learning and playing around with Azure security technologies, mainly as a preparation for AZ-500 (Microsoft Azure Security Technologies) exam.

And then... today I took the exam and... PASSED!

I must say, with a few certificates under my sleeve, this exam was not the easiest I took. I was feeling prepared and still - passing it demanded concentration on the details and a bit of thinking! Nonetheless, it's over now - one down, more to go!

Note that... by passing this exam, I'm not automatically an Azure security guru (!) - it just means that I know a thing or two about what Azure offers in terms of security and how it works. 🙂

What did I use to prepare?

There is a great book about Azure governance called Pro Azure Governance and Security, written by my MVP colleagues Peter De Tender, David Rendon and Samuel Erskine. It's purpose is not to be an exam prep guide, but to tackle into the world of governance and security features available within Microsoft Azure (which are part of the exam, who would know).

There is also a great post, containing a bunch of helpful AZ-500 material from Stanislas Quastana, located here, and Thomas provided some useful links in his post here and even did a webinar on Azure Security Center (hosted by Altaro) the other day - you can find the recording here.

Of course, there is also the official exam page with skills measured and docs.com.

And... don't forget to try things out yourself! There is also a free Azure subscription, you know?! 🙂

If you'll be taking this exam - good luck, hope this resources help you!

Cheers!

Windows Firewall blocking pings

A short one this time… Smile

Have you ever had an issue with Windows Firewall blocking your pings on a network using Public profile, although the “File and Printer Sharing” exception is enabled for this profile?
(oh, yes, and don’t you dare to say that Windows Firewall should be disabled by default! Smile)

So, this is what I’m talking about:

As you see in the previous picture, the exception is enabled for both profiles (this PC is not domain-joined, but it would be the same with domain-joined PC on a network which is using the Public profile). When I try to ping it, I’m getting the standard “Request timed out.” message. Why is that? Is this a feature or bug?

Well, I’ve deliberately left-out two things:

  • if I try to ping my machine from the same subnet, the ping is passing through
  • if I try to ping my machine from the different subnet (routing is all set and working OK, in case you’re wondering), the ping is not passing through

The security feature that enables this kind of behavior is set in Windows Firewall by default – by default, Windows Firewall allows ping (and other traffic) only from the Local subnet, for all networks that use the Public profile. Of course, you may want to change this in certain scenarios (and you can… easily).

This is yet another thing that should be kept in mind during troubleshooting, right? (hope it helps) Smile

Have a great weekend!

Microsoft Security Essentials

Novi BESPLATNI Microsoftov antivirus je konačno dostigao RTW (release to Web)!

Dorađeni nasljednik Windows Live OneCare sigurnosnog rješenja koji je već nekoliko mjeseci u beti, možete preuzeti na službenim stranicama.

S obzirom da ga koristim na svim svojim računalima otkako sam čuo za njega (odnosno, uključio se u testiranje), preporučio bih ga svima koji trebaju zaštitu od virusa/spywarea.

Kako do sada imam samo dobra iskustva sa ovim programom (a i njegovim prethodnikom), mislim da se isplati isprobati i vidjeti da li zadovoljava i vaše želje i potrebe...
