Embedded Web Device Security

Due to the increasing networking of devices and services to the Internet of Things, security requirements are rising. Systems that were previously operated in isolation can be attacked over the Internet today. Industrial control sys-tems often form the core of critical infrastructures. Their vulnerabilities and too lax security management can have fatal consequences. With the help of vulnerability databases and search engines, hackers can get instructions and targets to exploit. Routers, printers, cameras and other devices can be the gateway to the home or corporate network. Cyber criminals can enter sensitive areas through inadequately protected remote access. Appropriate security management and selected actions can reduce the risk of being hacked. A case study of the central control of water supply systems shows the potential of networked systems and also presents security problems and possible solutions for improvement.
