Interface Overview
netbobr is a single-page application organized into tabs. Session controls, the theme toggle and the active rules summary are in the header.
Main tabs
| Tab | Purpose |
|---|---|
| Manual Entry | Enter individual network flows (source, destination, protocol, port) and validate them. |
| Batch Import | Upload CSV files or cloud firewall configs to bulk-validate up to 500 rules at once. |
| Zones | Define security zones with CIDR subnets and configure zone-to-zone traffic policies. |
| Rules | Browse the rule catalog and enable or disable individual rules. |
Header
- How to Use - open the in-app guide. Docs, Blog and About open in a new tab.
- Session Control - opens the session buttons:
- Load - restore a saved session from a JSON file. Loading replaces all current state.
- Save - download your flows, results, zones and rule settings as a JSON file.
- Reset - clear everything: flows, results, zones, zone attributes, custom rules and rule toggles. It asks for confirmation first.
- Theme toggle - switch between dark and light mode.
See Session Management for what a session contains and how loading is checked.
Clearing inputs and results
Each input tab has its own Clear button. Neither one touches zones or rule settings:
- Manual Entry → Clear (next to Validate Flow) empties the flow inputs, removes extra flows and clears the results. It asks for confirmation first.
- Batch Import → Clear clears the results table, the upload status and import warnings. Your manual flow inputs are kept.
The app has a single results area, so either Clear empties it. To also remove zones, custom rules or rule toggles, use Reset in Session Control.
Framework toggles
Built-in structural rules are enabled by default but can be toggled off. Six additional compliance frameworks can also be enabled or disabled independently:
- PCI-DSS v4.0.1
- CIS Controls v8
- NIST 800-53
- NIS2
- DORA
- MITRE ATT&CK
When a framework is disabled, its rules are not evaluated and its findings disappear from results and exports. The 0-100 risk score is structural and does not count framework findings. Toggle frameworks on or off to match the regulatory scope relevant to your environment.
If every rule is switched off, Validate Flow and file imports show Enable at least one rule instead of results. Switch a rule back on and validate again.
Active rules indicator
The header shows an active rules count, for example 153/153, and how many frameworks are active. Click it to open the Rules tab.
The count includes only rules that are actually evaluated. A rule that is registered but not evaluated (DORA-NET-033, which needs a configurable list of financial messaging ports) is listed on the Rules tab with a "Not evaluated" tag instead of a toggle, and is left out of every count.
Live updates
Results on screen stay in step with your settings. Toggling a rule, or editing zones (adding or deleting a zone, adding or removing a subnet, changing a matrix cell or a default policy), re-analyses the displayed flows or batch rows. Your table sort and page are kept. The refreshed results also feed Export CSV.
