What is one potential issue with having a default SSID?

Having a default SSID can pose a significant security risk because it is often easily recognized by hackers. Many routers come with factory-set SSIDs that indicate the brand or model of the router, such as "Netgear," "Linksys," or "D-Link." This common knowledge allows malicious actors to identify potential targets and exploit default login credentials or known vulnerabilities associated with those router models.

Using a default SSID does not sufficiently obscure the network, making it simpler for hackers to gain access if other security measures aren't in place, such as strong passwords or encryption protocols. By changing the SSID to something unique and not easily associated with the hardware, network owners can obscure their network identity and add an additional layer of security against unauthorized access.

While the other options represent considerations in managing network settings, they do not directly address the security implications of having a default SSID as strongly as this choice does.
