Day 01: Data and Application & Intro to Confidential Ledgers(Lab)

  • What is Azure?
    • Azure is a cloud computing platform created by microsoft
    • It competes with the likes of AWS-Created by Amazon and also Google cloud which of course created by Google.
  • What is Azure Security?
    • Azure Security is the protection framework that ensures confidentiality, integrity, and availability of resources and services hosted on Microsoft Azure.

Azure Security Services: Data and Application Security

There are a few categories that we are being taught.

  • App Compliance Automation Tool
    • Essentially, it is a tool used to check apps if they meet the security and compliance standards.
  • Application security groups
    • Basically you can create one rule for a group of services or virtual machines to adhere to rather than creating a separate rule for each service.
  • Confidential Ledgers
    • Azure Confidential Ledger is a secure, tamper-proof database service that stores sensitive data in a way that even Microsoft or cloud administrators cannot alter or delete. It uses blockchain-like technology to ensure that once data is written, it cannot be changed or erased without detection.
  • Log Analytics workspace
    • Leverage unique environments for log data from Azure Monitor and other Azure services,
  • Web Application Firewall policies (WAF)
    • Create a Web Application Firewall policy to protect your web applications from common exploits and vulnerabilities.

Confidential Ledgers

  • Key features:
    • Immutable -> Once data is added, it cannot be modified or deleted.
    • Confidential -> Data is encrypted and processed in a secure, hardware-backed environment.
    • Tamper-Proof -> Any unauthorized changes are detected immediately.
    • Managed Services -> No need to set up complex blockchain networks; Azure handles it.
  • But what is block-chain?
    • “Blockchain is a digitally distributed, decentralised, public ledger that securely records transactions across a network of computers, making it transparent and resistant to tampering.”
    • The definition sounds the same as the Confidential Ledger.
