Computer security

Computer security, also known as cybersecurity or IT security, is the protection of information systems from theft or damage to the hardware, the software, and to the information on them, as well as from disruption or misdirection of the services they provide. It includes controlling physical access to the hardware, as well as protecting against harm that may come via network access, data and code injection, and due to malpractice by operators, whether intentional, accidental, or due to them being tricked into deviating from secure procedures.

The field is of growing importance due to the increasing reliance on computer systems in most societies. Computer systems now include a very wide variety of "smart" devices, including smartphones, televisions and tiny devices as part of the Internet of Things – and networks include not only the Internet and private data networks, but also Bluetooth, Wi-Fi and other wireless networks.

Vulnerabilities and attacks

A vulnerability is a system susceptibility or flaw, and many vulnerabilities are documented in the Common Vulnerabilities and Exposures (CVE) database and vulnerability management is the cyclical practice of identifying, classifying, remediating, and mitigating vulnerabilities as they are discovered. An exploitable vulnerability is one for which at least one working attack or "exploit" exists.

Risk

Risk is the potential of gaining or losing something of value. Values (such as physical health, social status, emotional well-being or financial wealth) can be gained or lost when taking risk resulting from a given action or inaction, foreseen or unforeseen. Risk can also be defined as the intentional interaction with uncertainty. Uncertainty is a potential, unpredictable, and uncontrollable outcome; risk is a consequence of action taken in spite of uncertainty.

Risk perception is the subjective judgment people make about the severity and probability of a risk, and may vary person to person. Any human endeavor carries some risk, but some are much riskier than others.

Definitions

The Oxford English Dictionary cites the earliest use of the word in English (in the spelling of risque from its Arabic original "رزق" ) which mean working to gain income gain and profit (see Wikipedia Arabic meaning ) as of 1621, and the spelling as risk from 1655. It defines risk as:

Plymouth University

Plymouth University is a public university based predominantly in Plymouth, England where the main campus is located, but the university has campuses and affiliated colleges all over South West England. With 25,895 students, it is the 22nd largest in the United Kingdom by total number of students (including the Open University). It has 2,820 staff.

Whilst the university has been known as Plymouth University since June 2011 as a result of a rebrand, the formal name and legal title of the university remains "University of Plymouth".

History

The university was originally a Polytechnic Institute, with its constituent bodies being Plymouth Polytechnic, Rolle College, the Exeter College of Art and Design (which were, before April 1989, run by Devon County Council) and Seale-Hayne College (which before April 1989 was an independent charity). It was renamed Polytechnic South West in 1989 and remained as this until gaining university status in 1992 along with the other polytechnics. The new university absorbed the Plymouth School of Maritime Studies.
