SFS 5: Networking and VPNs

All 16 sets · What is an SFS?

Assess network boundaries, segmentation, remote connectivity, and traffic controls, including VPNs, security groups, and zero-trust access policies.

Scope and boundaries

This set covers how devices and services communicate within a system and across external boundaries. It includes network inventories, routing, firewall and security-group rules, protected remote access, VPN configuration, and review of allowed connections. Questions should identify the relevant network paths and the evidence that demonstrates an enforced restriction or approved connection. Identity decisions belong to SFS 3, application-level protocol behavior to SFS C, and detection and response to SFS 6.

The sixteen questions

This set has sixteen SF positions, 0–F. Each position is one question, not another set. All questions below are unreviewed placeholders; no assessment result has been recorded.

From questions to a profile

Only reviewed, accepted 0/1 assessments can populate the sixteen-bit set profile. SF 0 is the most significant bit and SF F is the least significant bit. The completed result uses four hexadecimal digits, including leading zeros. There is no completed profile for this draft set.

Read assessment and validation, then encoding. A set profile preserves individual answers; it is not a summed security score.
