Lisäturvakerros

Lisäturvakerros, meaning "additional security layer" in Finnish, refers to a concept in information security and personal safety. It signifies the implementation of an extra measure or procedure beyond the standard or expected security protocols. The purpose of a lisäturvakerros is to enhance protection against potential threats, unauthorized access, or compromise. This could involve various techniques depending on the context.

In digital security, a lisäturvakerros often translates to multi-factor authentication (MFA). Instead of just a username and password, MFA requires users to provide two or more verification factors to gain access to a resource. These factors can be something the user knows (like a password), something the user has (like a security token or a smartphone), or something the user is (like a fingerprint or facial scan). Another example in the digital realm might be using a VPN in conjunction with a strong password policy.

In physical security, a lisäturvakerros could involve multiple locks on a door, a security guard in addition to an alarm system, or security cameras monitoring an area that is already protected by a fence. The core idea is redundancy and layered defense, where if one security measure fails or is bypassed, the additional layer provides a further obstacle. The effectiveness of a lisäturvakerros lies in its ability to complicate and deter malicious activities by increasing the effort and resources required by an attacker.
