The Azure Mask browser extension is a really great tool when either recording on-screen demos or sharing your screen. Available for Edge/Chrome and Firefox, @_clarkio‘s extension censors sensitive tenant information, so that your recording or viewers can’t see it. For example, the tenant ID within Azure AD’s overview page is blurred out.
If you’re doing a demonstration of any kind of security software with logs and auditing information, chances are you’ll get IP addresses on-screen too. If you’re running a lab environment at home or you’re showing off your own business’s production environment, you probably don’t what those seen by everyone, particularly if the session is going to be recorded.
The solution: Text Rewriter, a Chrome/Edge and Firefox extension.
Thanks! Full credit to @dotBATman on Twitter for pointing me in the direction of Text Rewriter!
With Text Rewriter installed, jump into the extension options (edge://extensions)
It operates using RegEx, where we enter a phrase to rewrite. Being a sane person, I Googled, rather than figured out myself, the RegEx of IPv4 addresses:
|
1 |
(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)(\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)){3} |
Place the RegEx into the phrase field, and however you want to censor it into the rewrite field, then save.
Now when web pages render, the extension dynamically updates any references to IPv4 addresses with the rewrite value.
This very simple tool really helps, and if you’re confident with RegEx you could go on to hide additional sensitive info that might show up in logs, such as ISPs or geographies.
