  Interconnecting "things" and devices that take the form of wearables,
sensors, actuators, mobiles, computers, meters, or even vehicles is a critical
requirement for the current era. These internetworked connections are serving
the emerging applications home and building automation, smart cities and
infrastructure, smart industries, and smart-everything. However, the security
of these connected Internet of things (IoT) plays a centric role with no margin
for error. After a review of the relevant, online literature on the topic and
after looking at the market trends and developments, one can notice that there
are still concerns with regard to security in IoT products and services. This
paper is focusing on a survey on IoT security and aims to highlight the most
significant problems related to safety and security in the IoT ecosystems. This
survey identifies the general threat and attack vectors against IoT devices
while highlighting the flaws and weak points that can lead to breaching the
security. Furthermore, this paper presents solutions for remediation of the
compromised security, as well as methods for risk mitigation, with prevention
and improvement suggestions.
