ABAC Basics: What Is Attribute-Based Access Control?
9 September 2025
Use CasesUnderstand exactly how phishing affects Copilot-enabled accounts through actionable insights, not just a list of files.
The Scenario
Your CFO’s account was phished at 08:12.
By 08:15, the attacker runs one Copilot prompt:
“Give me a quick view of M&A targets we discussed last week and their 2025 revenue projections.”
Copilot replies with a polished summary from finance decks, legal chat threads, and board minutes. Information that never lived in the same folder. Traditional red-team reports list “files accessible,” but executives care about what sensitive insight actually leaves the building.
Knostic creates a safe sandbox clone of any real user (C-suite, VP, contractor) without touching production.
A library of executive-style “attacker” questions probes for strategy, HR comp, M&A, IP, and PHI.
The platform stitches every snippet back to its sources and displays a heatmap of departments, data classes, and sensitivity levels exposed.
Risks ranked by sensitivity, access scope, and user context, so security teams can prioritize fixes that produce the most impact.
One-click fixes tighten labels or permissions; then easily rescan to prove the radius has shrunk.
A single view shows what insights are left, who they harm, and the cost if leaked.
Captures inferred knowledge that the LLM search assistant assembled from many “safe” fragments.
Remediation playbooks prioritize the top 20 % of gaps causing 80 % of risk.
Sandbox clones mean zero impact on live users or workflows.
Together, these capabilities move you from “we found a problem” to “we fixed it and can prove it.”
Core Capabilities
Provides the attacker-style prompt library and persona sandbox that drive the simulation. Documents all exposures and the prompts that surfaced them.
Verifies that applied fixes reshape GenAI replies and shrink the blast radius.
Converts heat-map findings into step-by-step tasks ranked by risk, owner, and effort.
Auto-suggests the precise Purview labels and DLP rules needed to eliminate the leaks uncovered.
