Information Security - All about Information Security in IT



Information security refers to protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction. The goals of information security include protecting the confidentiality, integrity and availability of information.

All organizations, including governments, military, financial institutions, hospitals, and private businesses, gather and store a great deal of confidential information about their employees, customers, products, research, and financial operations. Most of this information is collected, processed and stored on electronically and transmitted across networks to other computers. Protecting confidential information is a business requirement, and in many cases also an ethical and legal requirement. For the individual, information security has a significant effect on privacy and identity theft.

The field of information security has grown significantly in recent years. There are many areas for specialization including Information Systems Auditing, Business Continuity Planning and Digital Forensics Science, for example. There are also specific information security technical certifications that can assist getting started in this field.
