Security Foundations
An attack surface represents every pathway a threat actor could use to compromise your systems. It spans on-prem infrastructure, cloud assets, SaaS applications, and even third-party vendors.
Why it matters
- Larger attack surfaces increase the chance of misconfigurations, forgotten assets, and unmanaged accounts.
- Shadow IT, unused ports, and orphaned cloud services expand exposure without delivering business value.
How to shrink it
- Keep an authoritative inventory of internet-facing assets.
- Decommission unused services quickly.
- Apply network segmentation so one exposed entry point does not compromise everything.
- Continuously assess configurations against secure baselines.
