Abstract [sv]

I detta examensarbete görs en analys av säkerheten hos några av de driftundercentraler som används i fastigheter som Riksbyggen förvaltar. Driftundercentralerna används för att kontrollera olika delar i en fastighet, exempelvis belysning och temperatur. I de flesta fall nås respektive driftundercentral via en egen publik IP-adress, medan vissa tillverkare har en molntjänst för sina driftundercentraler. Syftet med examensarbetet har varit att undersöka de olika driftundercentralernas säkerhet, upptäcka brister och ge förbättringsförslag till dessa. Därutöver ges också exempel på hur smarta hem kan byggas upp.

Undersökningen har gjorts på flera sätt, dels med hjälp av kontrollerade attacker men även genom att samla information om driftundercentralerna och hur de fungerar. Utifrån de undersökningar som gjorts har ett antal brister kunnat konstateras, bl.a. när det gäller lösenordens styrka och kryptering av dessa. Generella förslag på förbättringar har getts för att minska sårbarheten för eventuella attacker som kan ske i framtiden.

Abstract [en]

This project presents an analysis of the security regarding some of the controllers which are used in real estates managed by Riksbyggen. The controllers are used to control different parts of a property, such as lighting and temperature. In most cases, the controllers are reached via their own public IP address, while some manufacturers have a cloud service for their controllers. The purpose with this project has been to examine the different controllers’ security, discover weaknesses and provide suggestions for improvements to these. In addition, examples are also given on how smart homes can be built.

The study has been made in several ways, partly with the help of controlled attacks but also by gathering information about the controllers and how they operate. Based on the studies that were made, a number of weaknesses have been observed, including passwords’ strength and encryption of these. General suggestions for improvements have been given to reduce the vulnerability for possible attacks that may occur in the future.
