What is the security of information?

The current pace of development of information systems has led to the fact that security and information protection ceased to be something of only theoretical interest. In many companies, employees are prohibited from using flash drives and similar media to prevent possible data leakage.
This is easily explained, if we recall that at the present time information can often cost much more than a material thing. These are the development trends. Not surprisingly, the security of information is a necessity. This is especially important for companies working with digital data - mail services, hosting, remote banking operations, etc.

Basics of protection

In the above areas, a complex information security center is used that controls a variety of parameters. Although each company has its own approach to implementing security, we point out some key points:

- Since electronic systems require the uninterrupted supply of all the key nodes with electrical energy, a necessary condition for reliable operation and data integrity is the availability of backup power lines. These can be autonomous generators, batteries, spare lines.

- The security of information can not be sufficient until in the automatic mode periodic backup of important (or protected) data to the backup medium is performed.

- To ensure the uninterrupted operation of all computational modules, it is necessary to solve the problem with the conditions of their operation: the ambient temperature, dust and humidity should be within acceptable limits.

In addition to these three points, an indispensable condition, without which the security of information is unthinkable, is the availability of software protection methods. These are complex anti-virus systems, access control, use of SSL encryption.

Practice for a simple user

Since the term "information security" is too general, this article will deal with a particular case - the protection of digital data in a computer.

Sometimes it may seem that the data on a regular user's media does not represent a particular interest. However, the abundance of keyloggers, viruses and other malicious programs makes us think about the correctness of this belief.

We will point out the most important element of any security system: compliance with certain rules for working with data in the global network and on third-party media. And software tools for protecting information is a superstructure over rules.

We list them:

- You should avoid visiting suspicious resources. Usually the information you seek can be found on other sites. Some modern browsers (Dragon, Chrome) warn of an attempt to visit a page with malicious code. Their capabilities can be expanded by installing the WOT add-on.

- Do not once again indicate on the pages of sites their data: email address, mobile phone number (no confirmation!), Access codes and passwords.

- You can not open messages whose sender is unknown.

Software protection should be implemented by complex systems. That is, only one antivirus is small. Any of the two solutions is acceptable: the installation of a kind of combine harvester that has absorbed all the basic protective solutions. This is KIS, NOD Security Suite, Dr.Web Space or manual layout. For example, the Outpost Firewall + Avira antivirus is quite viable.
