Authentication codes changing frequently signifies what about network security?

1. They are static

2. They remain the same

3. They enhance security

4. They are irrelevant

The correct answer is: They enhance security

Changing authentication codes frequently is a crucial practice in enhancing network security. When authentication codes, such as passwords or tokens, are updated regularly, it limits the window of opportunity for unauthorized access. If a code is compromised, frequent changes ensure that the old code is quickly rendered useless, thereby protecting sensitive data and resources. Additionally, dynamic authentication codes can deter potential attackers since simply having access to a code becomes less valuable if it is bound to change. This adaptability in security measures helps protect against various threats, including replay attacks, where an attacker might use stolen credentials to gain unauthorized access. Consistently rotating these codes is a proactive approach to maintaining a secure network environment, reinforcing the principle that security should be designed to evolve in response to emerging threats.
