Security in Modern Computer Systems, HW Trojans and SW
Vulnerabilities: Threats and Emerging Solutions
Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, to software and to information on them, as well as from disruption of the services they provide. This means that it is mandatory to secure physical access to these systems by protecting them against harm that may come via network access, data/code injections and malpractice from operators (designers), whether intentional or accidental. This field is of growing importance due to the increasing reliance on computer systems and "smart" devices (such as smartphones, smartTVs and tiny devices) as part of the IoT via wireless network (Bluetooth and Wi-Fi). This talk briefly describes hardware trojans' taxonomy and the most common software vulnerabilities mentioned by specialized literature. Current solutions and the cost/benefit to neutralize these threats are also discussed.
