Reverts commits 8c249f6, a6c7cfd, 7ff5703. The SSH log relay approach
requires container redeployment and doesn't retroactively fix existing
attacker profiles. Rolling back to reassess the approach.
New log_relay.py replaces raw 'cat' on the rsyslog pipe. Intercepts
sshd and bash lines and re-emits them as structured RFC 5424 events:
login_success, session_opened, disconnect, connection_closed, command.
Parsers updated to accept non-nil PROCID (sshd uses PID).
The SSH honeypot logs commands via PROMPT_COMMAND logger as:
<14>1 ... bash - - - CMD uid=0 pwd=/root cmd=ls
These lines had service=bash and event_type=-, so the attacker worker
never recognized them as commands. Both the collector and correlation
parsers now detect the CMD pattern and normalize to service=ssh,
event_type=command, with uid/pwd/command in fields.
- Modify Rfc5424Formatter to read decnet_component from LogRecord
and use it as RFC 5424 APP-NAME field (falls back to 'decnet')
- Add get_logger(component) factory in decnet/logging/__init__.py
with _ComponentFilter that injects decnet_component on each record
- Wire all five layers to their component tag:
cli -> 'cli', engine -> 'engine', api -> 'api' (api.py, ingester,
routers), mutator -> 'mutator', collector -> 'collector'
- Add structured INFO/DEBUG/WARNING/ERROR log calls throughout each
layer per the defined vocabulary; DEBUG calls are suppressed unless
DECNET_DEVELOPER=true
- Add tests/test_logging.py covering factory, filter, formatter
component-awareness, fallback behaviour, and level gating
