Making opportunistic cyberattacks harder by design

Microsoft’s security approach to defending against opportunistic cyberattacks centres on credential elimination and platform engineering to make attacks harder by design. The guidance emphasises removing secrets from systems, using managed identities and federated identity patterns to prove workloads’ identities without passwords or API keys, and implementing Power Platform Managed Identity for components like Dataverse plugins and Power Automate.

It also highlights reducing public surfaces by private endpoints, brokered access, and token-based, least-privileged access to limit attacker movement after initial access. Platform engineering is presented as essential at scale, standardising compute and communications, enforcing consistent controls, and ensuring security is baked in rather than bolted on.

The article notes that credential elimination and platform engineering are foundational, requiring long-term coordination, and that Microsoft’s core services—across more than 450 services—benefit from centralized, reusable security patterns and evidence-based governance aligned with Secure Future Initiative goals.

Overall, the message is that a security-by-design mindset, shared defaults, and consolidated platform controls can dramatically shrink the attack surface and impede attackers, even when they gain a foothold nearby.
