Abstract
The Internet of Things (IoT) is a new paradigm that enables the convergence of
smart objects and the internet. It is an intelligent network that connects all things
to the Internet for the purpose of exchanging information and communicating
through the information sensing devices in accordance with agreed protocols.
Aside the various benefits IoT provides, it also presents challenges related to
security and privacy. The direct connection of IoT devices to the internet makes
them susceptible to several security threats.
Some ongoing projects for enhancing IoT security include methods for providing data confidentiality and authentication, access control within the IoT network, privacy and trust among users and things, and the enforcement of security
and privacy policies. However, even with these mechanisms, IoT networks are
vulnerable to multiple attacks aimed to disrupt the network. For this reason,
another line of defense, designed for detecting attackers is needed. Intrusion
Detection Systems (IDSs) fulfill this purpose.
Previous resarch works propose IDSs in relation to IPv6 over Low-power
Wireless Personal Area Network (6LoWPAN). However, since IoT will be used
in many application domains with different technologies (WiFi, BLE, NFC and
Z-Wave), development of IDSs only for 6LoWPAN is insufficient to meet the
security needs of every IoT system.
This research work focuses on IDSs for IoT devices that use WiFi technology.
No previous works address IDSs for IoT devices that use WiFi technology. The
research proposes lightweight intrusion detection algorithms that addresses ManIn-The-Middle (MITM) and Rogue Access Points (RAP) attacks. It goes further
to propose an orchestration framework for IoT devices which can be used to
logically isolate these devices in instances where vulnerabilities are found on them.
