Securing information is extremely important in today's day and age. In this lesson, we'll take a look at information security, what it is, what information security management is, and the systems that enforce it.

Information, the Key to Everything

Information is important to us. We use credit card information when we purchase something, our families use recipe information when they prepare meals, and companies use account information for sales and billing efforts. It's hard to imagine our world without information. But with it comes a certain responsibility, a need to protect that information.

For example, passwords are often used to protect networks and accounts, swipe cards or fobs are used to access to non-public areas, and in sensitive areas biometric methods like fingerprints and retinal scans are used. Each of these methods is unique, which is characteristic of the different situations information security must handle.

What is Information Security Management System?

An information security management system (ISMS) is a collection of policies and procedures meant to safeguard information no matter where it is used. Many businesses employ information security management, although it varies greatly depending on the business in question. As an example, think about the place you work.

These are examples of information security management in action, and they are there to ensure that business information remains in a pristine state.
