The Internet of Things (IoT) is a developing technology which allows any type of network device inside a home to be linked together. IoT is based on older Wireless Sensor Network (WSN) technology and has been reduced to smaller size and scale for home use. However, both the original WSN and developing IoT technology has inherent security flaws. This paper identifies and evaluates security issues and their underlying causes in IoT technology. We focus on IoT reliance on known exploitable network ports and the difficulty of recovering from such attacks. Most IoT implementations utilize Telnet to communicate between devices. We explore the vulnerability of Telnet connections through a simulated IoT environment. Our results show that Telnet vulnerabilities can be exploited by attackers and grant access over IoT devices allowing the modification of devices and subtle spying on any data being transmitted.
