Information is processed data obtained from raw facts. Information security aims to safeguard data by ensuring confidentiality, integrity and availability (CIA) through technical, administrative and physical protections. While technology plays an important role, people are the key factor as over 90% of security issues are caused by human error. When online, one should use strong and private passwords, lock computers when unattended, avoid risky sites, beware of email attachments that could contain Trojans, and use tools like SiteAdvisor to surf more safely.
