Top 110 Cyber Security Interview Questions & Answers

Computer security , cybersecurity [1] or information technology security IT security is the protection of computer systems and networks from information disclosure, theft of or damage to their hardware , software , or electronic data , as well as from the disruption or misdirection of the services they provide. The field is becoming increasingly significant due to the increased reliance on computer systems , the Internet [2] and wireless network standards such as Bluetooth and Wi-Fi , and due to the growth of "smart" devices , including smartphones , televisions , and the various devices that constitute the " Internet of things ". Owing to its complexity, both in terms of politics and technology, cybersecurity is also one of the major challenges in the contemporary world. The April session organized by Willis Ware at the Spring Joint Computer Conference , and the later publication of the Ware Report , were foundational moments in the history of the field of computer security. Protecting information systems includes evaluating software, identifying security flaws, and taking steps to correct the flaws, which is a defensive action. Collecting intelligence includes exploiting security flaws to extract information, which is an offensive action.

Network security is any activity designed to protect the usability and integrity of your network and data. If you're looking to increase protection for your remote employees so they can work from any device, at any time, from any location, get started with the Cisco Secure Remote Worker solution.
