WC-B-02Level 1 · Signal
Bypasses web filtering
A risky Behavior signal from the web security layer (SSE, web.block.bypassed): this person got past a block page or the proxy through a personal VPN, a proxy site or an override.
Classification
- Risk domain One of 9 areas of human risk, from social engineering to readiness and response. Every signal belongs to one.
- Evidence level
- Maturity practices One capability a program performs, scored on its own: See, Understand, Act, Prove, Govern and Culture.
- Leads to The kind of breach the evidence beneath it points toward, each anchored to a Verizon DBIR or VERIS pattern or an FBI IC3 category.
- NIST CSF 2.0
