📋 Biography
I'm 24 years old, been a developer and now a VoIP & Cloud Technician. Lucky to have always been keen to IT and having found a way into this field, where you never stop learning. In a world where you never stop learning, it is also good to share knowledge and real-world experiences, I started doing so after after realizing that, without the generosity of countless people on the Internet, I wouldn’t have been able to achieve some of my goals so quickly — or even at all.

In this GitHub repository it is all the required components to deploy two Azure Functions (for region redundancy) and a traffic manager (for request routing) for serving MTA-STS policies for email security. Azure resources can be deployed with the template shared in the repository, by customizing the specific values (region, names, etc.) in the parameters files. Afterwards it is only required to configure the MTA-STS policies in the specific JSON file contained in the Azure Function project folder and proceed with the code deployment. With these two functions it is possible to serve MTA-STS policies for multiple domains by adding the custom ones to both the functions. The function code is written in PowerShell and doesn't require external modules.

Il VoIP ha ormai soppiantato la telefonia tradizionale, ma questa migrazione porta con sé un prezzo: la voce diventa un servizio IP, e con essa eredita tutte le fragilità della rete. I protocolli di segnalazione e trasporto non sono nati con la security in mente: intercettazioni e spoofing sono minacce concrete e spesso sottovalutate. Analizziamo i protocolli alla base della telefonia IP, evidenziando le possibili vulnerabilità e quali strategie di hardening permettono di ridurre questi rischi.
Shared on GitHub a PowerShell script that can be used by people trying to connect Microsoft Teams Phone Resource Accounts to Azure Communication Service and related Event Grid by using the new Teams Phone Extensibility functionality. This script allows to add a resource account to the allowed list, remove a resource account to the allowed list and checking if a specific resource account is authorizied or not.
