You are a systems administrator recommending best practices for securing employee access to the company network. Why might using text messages for two-step verification be considered less secure compared to other methods?
Text messages are at risk of interception by attackers using techniques like SIM swapping.
The cost of sending text messages may present challenges for large organizations.
Text messages lack encryption, allowing them to be readable during transmission.
Text message-based verification may not be compatible with devices that all users have.
While text message-based two-step verification adds a layer of security by requiring a second factor for authentication, it is considered less secure because text messages are at risk of being intercepted or redirected by attackers using techniques such as SIM swapping. Methods like authenticator applications or hardware tokens are generally more secure alternatives.
