Jälkivarmistus

Jälkivarmistus refers to a security process or procedure that is performed after a primary authentication or authorization step has occurred. It is designed to provide an additional layer of assurance or to verify the legitimacy of a user or transaction. This can involve various methods depending on the context.

In the realm of cybersecurity, jälkivarmistus might be implemented as multi-factor authentication, where after entering a password, a user is prompted for a secondary verification, such as a code sent to their phone or a biometric scan. This helps to prevent unauthorized access even if the initial credential is compromised. In financial transactions, it can involve sending a confirmation code or requiring a signature for high-value purchases.

The purpose of jälkivarmistus is to mitigate risks that might arise if the initial security measure alone is insufficient. It adds complexity to the access or transaction process but significantly enhances overall security. The specific implementation details of jälkivarmistus vary widely across different systems and industries, tailored to the security requirements of the given context.
