About security of proxy servers
Today, there is an acute issue of information security when exchanging data via the Internet. But despite this, the spread of the World Wide Web and the active use of online servers is becoming widespread. Sending documents, communicating or carrying out financial transactions using the Internet is becoming a daily necessity. To ensure the protection of user information and prevent theft of personal data, an effective authentication system is needed to ensure that the identity of the user is verified reliably. On the Proxy-Seller.com website you can buy the most reliable IPv4 and IPv6 proxies with HTTP (s) and Socks5 support at high speeds.
Information security protocols on the network
Protection rules are implemented in separate protocols and define the type of allowed and unacceptable actions for the system (users, services, data, machines, etc.). Protection mechanisms include:
- Encryption (transformation) of data into a state that cannot be understood by outsiders. It is a privacy enforcement tool.
- Authentication is the process of verifying and confirming the identity of a subject or object.
- Authorization - granting an identified user rights in accordance with his access level.
- Audit - control of user actions.
Proxy, in the context of protecting computer systems, is a token that allows you to operate with the rights and privileges of their owner. It should be possible to verify that the proxy was provided by the entity that it is named by. This is an authentication issue.
The proxy implementation entails a number of certain drawbacks. First, anyone who controls it can use the technology. This may not be a problem, but in many cases it should be possible to specify who can act on its behalf. Secondly, a user provided with a proxy token can perform all actions available to the subject who provided it on any server with original access rights. The server that will be given restricted proxies must be able to ensure that the restrictions have not been tampered with. Among the often cited restrictions are those that can only be used by established subjects or restrictive operations available for execution.
