What is Cyber Security?

Cyber security is the practice of protecting information and data from outside sources on the Internet. Cybersecurity professionals provide protection for networks, servers, intranets and computer systems. It also ensures that only authorized people have access to that information. In an office setting, one individual might go to another’s computer, install a flash drive and copy confidential information. This falls more under the category of information security. If someone halfway across world manages to hack into another company’s network and breach their system, this company is in need of better cyber security.

What is Information Security?

Information security is all about protecting information and information systems from unauthorized use, assess, modification or removal. It’s similar to data security, which has to do with protecting data from being hacked or stolen. Data is classified as information that means something. All information is data of some kind, but not all data is information. When certain things are stored in a computer system, they are considered data. It isn’t until it’s actually processed that it becomes information. Once it becomes information is when it needs protection from outside sources. These outside sources may not necessarily be in cyberspace.

Difference Between Cyber Security and Information Security

While many people still consider them one and the same, they’re actually different. Their capabilities are different. They both officer protection against information and data being stolen, accessed or changed, but that’s where the similarities end. Information doesn’t have to be on a computer to be in need of an information security system. Even if it’s stored in a file cabinet, it needs good information security. Cybersecurity deals with protecting data and information from outside sources in cyberspace or the Internet.
