Challenges in security in Internet of Things

Nowadays, Internet of Things is one of the future developing directions. Some of the most important challenges it faces are related to security. Several massive distributed denial of service attacks have been deployed in the last months using “smart” devices, such as baby monitors or refrigerators. Connecting electronic devices without considering security can lead to severe problems. Using encryption and authentication, the devices can check if they are allowed to trust a remote system. The code that runs should be authorized, to avoid malicious applications and the devices should be permanently updated with security patches. Traffic analyzers are also part of IoT security, for monitoring patterns and be able to find abnormal traffic.
