Protecting information on the Internet - is it important

In the age of computer technology, the problem of information security is as acute as never before. Of course, the worldwide network has brought many positive aspects to the lives of millions of people, however, it is now increasingly difficult to keep any personal data secret from others. Particularly difficult is the protection of information on the Internet, where all the data is more or less accessible to users. Not a single person can be insured against the fact that an outsider will not invade his personal space , who will use the information at his discretion.

Network Data Protection - Securing Your Own Security

Currently, the protection of information in computer networks has become the main task of thousands of specialists around the world, however, all technologies quickly become obsolete, and you have to look for new ones. People who specialize in hacking sites and databases, who call themselves hackers, come up with new ways to trick the security system every minute, so you can’t keep up. It is information that today has become an international currency, therefore, for the sake of obtaining it, even crimes are used. This is partly due to the imperfection of the punishment system, because it is very difficult to prove the fact of data theft, and it is even more difficult to attach it to a certain person. Therefore, each company is obliged to take care of the safety of its secret files, using one or another protection method.

The problem of data security - can it be resolved

Three main problems can be distinguished, because of which the protection of information on the Internet is now especially important:

- violation of confidentiality;

- distortion of the message or its substitution;

- data theft and copyright infringement.

What is the protection of information on the Internet based on? Let's consider in more detail

Information protection on the Internet is based on the principles of eliminating or complicating the ability to select means for receiving and decrypting data (with their further conversion to normal files) - this uses a different type of encryption. If the same key is used to encrypt and read a file, then it is called symmetric, but its main drawback is the long processing time, and for its transfer you must also use a secure channel, but this is already a completely different level of protection.

This is partly why the protection of information on the Internet is carried out by most users using asymmetric keys, that is, several of their types are used at once. This method is considered quite reliable, since you can decrypt one half of the file, but only decrypt the other half. Most users deal with only one part of the key, and the second part is securely hidden.

Types of data protection and their provision

One of the most reliable is software and hardware information protection, which is based on several principles. First of all, the user must have a sufficient level of tolerance for working with data, and also have all the necessary information for this. Such protection of information on the Internet can be used by the site administration, but it is also applicable for protection within a company or other limited circle of users. In addition, such a system allows you to transfer any files only to specially marked media, or removes this option altogether. Each user is personally responsible for their actions, all of his commands are registered by the computer and entered in special log files. Although the user is working in the system, he does not have any access to the security features, since they are generally allocated in a separate independent module.

Of course, reliable protection of information on the Internet will be possible only when all users follow the safety rules and follow the clear instructions of system administrators or other specialists in the field of computer systems protection.
