Protection of information from unauthorized access - a prerequisite for working on the Internet
Everyone who deals with computers andInternet, knows what is fraught with disorderly attitude to the issue of security. This can entail the destruction of your data, their copying or destruction, a simple introduction. Therefore, the protection of information from unauthorized access to it is a prerequisite when working on the Internet. Otherwise, you can get at least financial damage, lose time, and even customers.
What kind of protection fromunauthorized access to information? Let's talk about it in plain language, so that the ordinary user can understand. There are two basic and mandatory ways. First, we are talking about network protection. In general, the computer is trying to penetrate from the outside, and for this reason the issue of network security must be given paramount importance.
To counteract need highly professionalsystem administrators, special programs and a properly configured VPN network. There are special scanners that periodically need to check the connection. They will provide all the information about the network map, its problem areas. At this stage, everything can be easily corrected and eliminated.
Secondly, the protection of information fromunauthorized access is performed using software. Protective utilities are loaded even before the operating system starts, require at least a password, which prevents them from being deleted, damaged or modified by attackers.
Consider the means of protecting information fromunauthorized access. The main means here, as already mentioned, are firewalls. They protect workstations from illegal users.
Confidentiality of information is provided by cryptographic protection. When it is used, personal information is encrypted, electronic signatures are created, the authenticity and integrity of the files are guaranteed.
To protect the information that is transmittedcommunication channels that are open to all, a so-called VPN connection is used. To detect the vulnerabilities of the local network and workstations, special analysis tools are used. To protect against the effects of malicious programs - antiviruses.
Protection of information from unauthorized accessis also provided by means of technical means. After all, you can take your data off using an acoustic / vibro-acoustic channel or electromagnetic radiation and interference.
What is the easiest way for an attacker?to get to your information? Connect to your computer and have everything you need, view or download. To prevent an unauthorized person from turning on your device, authentication and user authentication procedures have been developed.
The simplest way of such procedure is the introductionuser name (so-called login) and password. The harder they are, the better. But at the present time, biometric identification and authentication, which uses the parameters and characteristics of a person: fingerprints, the retina pattern, the voice features, the shape of the ears and so on, is gaining ground.
Such protection of information from unauthorized access is a great obstacle for falsification, which will ensure maximum safety of your confidential files.
