computer security
Protection against unauthorized access to, or
alteration of, information and system resources including
CPUs, storage devices and programs.
Security includes:
* confidentiality - preventing unauthorized access;
integrity - preventing or detecting unauthorized
modification of information.
* authentication - determining whether a user is who they
claim to be.
* access control - ensuring that users can access the
resources, and only the resources, that they are authorised
to.
* nonrepudiation - proof that a message came from a certain
source.
* availability - ensuring that a system is operational and
accessible to authorised users despite hardware or software
failures or attack.
* privacy - allowing people to know and control how
information is collected about them and how it is used.
Security can also be considered in the following terms:
* physical security - who can touch the system to operate or
modify it, protection against the physical environment - heat,
earthquake, etc.
* operational/procedural security - who is authorised to do or
responsible for doing what and when, who can authorise others
to do what and who has to report what to who.
* personnel security - hiring employees, background screening,
training, security briefings, monitoring and handling
departures.
* System security - User access and authentication controls,
assignment of privilege, maintaining file and filesystem
integrity, backup, monitoring processes, log-keeping, and
auditing.
* network security - protecting network and
telecommunications equipment, protecting network servers and
transmissions, combatting eavesdropping, controlling access
from untrusted networks, firewalls, and intrusion detection.
Encryption is one important technique used to improve data
security.
