Q&A

Introduction

Common project with Electronics guys

Some sort of Solar-PanelNeeds to move according to the Sun's position on the sky

Keep logs and transfer them to a central server

Manual override of all automated tasks

Half liveExplosurePrelevanceperstitance

PLM Protocol

Position Lean Protocol

Manual override of automated tasksPosition of the Solar-Panel

Force transfer of the logs

Force shutdown

Considerations for implementationOn top of TCP

Security

Reliability not so important

Loads files to memory for later printing. when printer sharing is enabled, does not properly validate spooler access permissions, which allows remote attackers to create files in a system directory, and consequently execute arbitrary code, by sending a crafted print request over RPC

LTP Protocol

Logs Transfer Protocol

Transfer Logs from the Solar-Panel to central ServerMaybe some sort of live think can be implemented also

Considerations for implementationHybrid between UDP and TCP

Uses a shit-load of bandwidth

Security - is not a problem

Reliability is important

An attacker can obtain a client's public host key during a connection attempt and use it to open and authenticate an SSH session to another server with the same access rights as the victim.
