Protection of semantic analysis and relevance of information
At the level of information presentation, protection against the threat of denial of access to information (protection of the semantic level) can be considered as countering the comparison of syntactic constructions used (words of some alphabet, symbols, etc.) of certain semantic content. To a greater extent, this task relates to the field of linguistics, which considers the change in the meaning of words over time, translation from a foreign language and other similar scientific and applied fields of knowledge.
In relation to information systems, the protection of information content from the threat of blocking access (failure of functioning) means the legal validity of the processing and use of information.
The effectiveness of integrity control methods is mainly determined by the characteristics of the cryptographic encryption tools used - digital signatures, hash functions.
The issues of ensuring timely and unhindered access to information are becoming increasingly important with the development of distributed processing systems.
The complexity of the topology of the systems, the hardware used and the software used, as well as the task of interfacing all elements require increased attention to ensuring the operability of the system and the availability of information circulating in it.
A separate area of protection is ensuring the secrecy of the parameters of the information system in which confidential information circulates. The methods of protecting the parameters of such a system are similar to the general methods used to protect the confidentiality of information.
