The availability of information means that subjects who have the right to access information can use it without hindrance at any time. There are several different types of access rights to information. These are the rights to read, copy, modify and delete it. In order to avoid loss of information access rights, it is important to distinguish between people.

Accessibility is the guarantee that authorized users can access and work with information assets, resources and systems that they need, while ensuring the required performance. Ensuring accessibility includes measures to maintain the availability of information, despite the potential for interference, including system failure and deliberate attempts to violate accessibility. An example would be access protection and ensuring the throughput of the mail service.

Accessibility is a property of information that ensures that people who have access to information can access at the right time.

For example. The general director of the firm “Mercury” came to work on Monday morning, turned on the computer and was surprised to find that he could not open the sales base for sales. So what happened? Elementary Watson! On Sunday night, a pipe burst in the ceiling, water got into the computer where the base was stored, and the hard drive burned safely. Since the director has never heard of information security, and the local network was created by a student, there was no backup or redundancy in the form of RAID. This is the simplest example, you can cite a bunch of examples, the company's website was not available and the client could not open the website of one company, but opened another website and naturally bought the product of the second company.
