Information security

Information security definition
Information security, sometimes abbreviated to infosec, is a set of practices intended to keep data secure from unauthorized access or alterations, both when it's being stored and when it's being transmitted from one machine or physical location to another. You might sometimes see it referred to as data security. As knowledge has become one of the 21st century's most important assets, efforts to keep information secure have correspondingly become increasingly important.

Information security measures
As should be clear by now, just about all the technical measures associated with cybersecurity touch on information security to a certain degree, but there it is worthwhile to think about infosec measures in a big-picture way:


 * Technical measures include the hardware and software that protects data — everything from encryption to firewalls
 * Organizational measures include the creation of an internal unit dedicated to information security, along with making infosec part of the duties of some staff in every department
 * Human measures include providing awareness training for users on proper infosec practices
 * Physical measures include controlling access to the office locations and, especially, data center
