Security

Philosophy

O is designed to support freedom above a protected base, not instead of one.

The system should remain:

  • open
  • programmable
  • transparent
  • recoverable
  • difficult to casually damage
  • hard to tamper with at the trust/root level

Security layers

Kernel/protected root

  • safe boot
  • protected secure folders
  • trust anchors
  • destructive-action barriers
  • recovery path
  • non-bypassable safety hooks

Mother O security services

  • firewall
  • privacy ledger
  • trust management
  • code risk analysis
  • superuser gating
  • promotion validation
  • incident response

Sub O policy layer

  • isolation
  • runtime restrictions
  • network mode
  • device access
  • relation policy
  • snapshot and destruction controls

User mode layer

  • normal
  • visible
  • strict
  • paranoid
  • dead man mode
  • drunk mode
  • child lock mode
  • user-defined experience modes

Firewall model

Sub O internet access is off by default unless allowed.

Mother O network posture is user-selectable:

  • local (including server)
  • online repo only
  • full online

The firewall should expose an understandable app/path/data-use view similar to a simplified process/network monitor.

Privacy ledger

The privacy ledger is always available. Live on-screen visibility is optional.

It records:

  • data sent and received
  • source and destination
  • files touched
  • subsystem involved
  • model use
  • device use
  • updates and mutations

Code risk

Risk evaluation combines:

  • static rules
  • runtime observation
  • small-model intent explanation

Behavior:

  • safe → allow
  • suspicious → warn
  • high-risk → hold for confirmation or stronger path

Recovery and reinstall

Fresh reinstall and trusted recovery are part of the security model. O should always maintain a path back to a trusted state.
