Computer security

Computer security is a field of computer science concerned with the control of risks related to computer use.

The means traditionally taken to realize this objective is to attempt to create a trusted and secure computing platform, designed so that agents (users or programs) can only perform actions that have been allowed.

This involves specifying and implementing a security policy.

The actions in question can be reduced to operations of access, modification and deletion.

Computer security can be seen as a subfield of security engineering, which looks at broader security issues in addition to computer security.

Target Data Breach Shines Focus on Lack of IT Security Talent

Target Data Breach Shines Focus on Lack of IT Security Talent

TheStreet (Feb. 26, 2014) Hewlett-Packard's head of security products Art Gilliland says cyber attacks, like the one at Target late last year, highlight the need for more skilled workers in the IT security space. Gilliland says the latest figures show there is a 40-percent vacancy rate in IT security jobs in 2014 and a 58-percent vacancy of jobs at the supervisor level. HP, along with the Ponemon Institute, also found roughly 56-percent of companies do not have chief information security officer as part of their C-Suite team. Gilliland says companies are also competing with each other on the pay front where the competition for talent is fierce and some aren't able to offer competitive salaries.

Starbucks to Roll Out App Update in Effort to Fix Security Flaw

TheStreet (Jan. 17, 2014) After security researcher Daniel Wood disclosed earlier in the week that the Starbucks app stores user names, email addresses, passwords and even geolocation information in unencrypted, clear text, Starbucks executives confirmed that app users' information could be visible to anyone with access to the phone if it was connected to a computer. So, if a user's phone was stolen, that information could be accessed by the thief. The company said it will soon roll out an update for its app to make it more secure, though it said the app for Google's Android operating system does not contain the vulnerability.
