Protecting information on the Internet - is it important

In the age of computer technology, the problem of protectioninformation is as acute as never before. Undoubtedly, the global network has brought many positive moments to the lives of millions of people, however, it is now increasingly difficult to keep any personal data secret from others. Especially difficult is the protection of information on the Internet, where all data is more or less accessible to users. No person can be immune from the fact that an outsider will not intrude into his personal space, which will take advantage of the information received at his discretion.

Data protection in the network - ensuring your own security

At present, the protection of information incomputer networks has become the main task of thousands of professionals around the world, however, all technologies quickly become obsolete, and we have to look for new ones. People who specialize in hacking sites and databases that call themselves hackers, every minute come up with new ways to deceive the protection system, so you can not lag behind. It is information that has become an international currency today, so for the sake of getting it, even crimes are committed. This is partly due to the imperfection of the penal system, because it is very difficult to prove the fact of data theft, and it's even more difficult to tie it to a certain person. Therefore, each company must itself take care of the security of its secret files, using some form of protection.

The problem of data integrity is whether it can be resolved

We can distinguish the main three problems, because of which the protection of information on the Internet is now particularly important:

- violation of confidentiality;

- distortion of the message or its substitution;

- Data theft and copyright infringement.

What is the basis for protecting information on the Internet? Let's consider more

Protection of information on the Internet is based onthe principles of exclusion or difficulty in selecting the means for obtaining and decrypting data (with their further conversion to normal files) - this is the type of encryption used. If the same key is used to encrypt and read the file, then it is called symmetric, but its main drawback is a long processing time, and for its transfer one must also use a protected channel, but this is already a completely different level of protection.

This is partly why information security isInternet is carried out by the majority of users with the help of asymmetric keys, that is, several of their types are applied at once. This method is considered quite reliable, because you can decrypt one half of the file, but only by deciphering the other half. The bulk of users deal with only one part of the key, and the second part reliably hides.

Types of data protection and their provision

One of the most reliablesoftware-hardware protection of information, which is based on several principles. First of all, the user must have a sufficient level of tolerance to work with the data, and also have all the information necessary for this. Such protection of information on the Internet can be used by the site administration, but it is also applicable for protection within the company or other limited number 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 his actions, all his commands are registered by a computer and recorded in special log files. Although the user is running on the system, he does not have any access to the security tools, since they are generally allocated to a separate independent module.

Certainly, reliable information protection inInternet will be possible only when all users comply with security rules and follow clear instructions of system administrators or other specialists in the field of protection of computer systems.
