Feketelistázás

Feketelistázás is a Hungarian term that translates to "blacklisting." It refers to the practice of excluding individuals, entities, or specific items from a system, network, or opportunity. This exclusion is typically based on a predetermined set of criteria, often related to negative past behavior, perceived risk, or a violation of rules.

In the context of telecommunications, feketelistázás commonly applies to phone numbers. Service providers may blacklist certain numbers to prevent spam calls, harassment, or fraudulent activities. This means calls or messages originating from blacklisted numbers will be blocked or diverted. Individuals can also create personal blacklists on their devices to block unwanted contacts.

Beyond telecommunications, the concept of blacklisting can appear in various domains. For example, a company might blacklist a supplier due to poor performance or ethical concerns. In cybersecurity, IP addresses or email addresses can be blacklisted to prevent malicious traffic. The act of blacklisting generally serves as a protective measure to maintain the integrity and security of a system or to enforce specific policies. The criteria for blacklisting are usually established by the entity implementing the blacklist and can vary widely depending on the context.
