Final answer:
Security through obscurity refers to the practice of achieving security by hiding or concealing system functions. In the context of the options provided, hiding the SSID broadcast is an example of security through obscurity because it conceals the network's presence without actively securing it.
Step-by-step explanation:
The concept of security through obscurity refers to the practice of achieving security by hiding or concealing certain system functions or processes. It can give a false sense of security because if the obscurity method is discovered, the system can easily be compromised.
Among the options provided, hiding SSID broadcast is a form of security through obscurity. By hiding the Service Set Identifier (SSID), the network does not openly broadcast its name, making it less visible to casual users. However, this does not prevent individuals with the right tools from detecting the network and potentially breaching its defenses.
- MAC address filtering involves limiting device access to a network based on their physical hardware address. It provides some security but is not based on obscurity.
- Using WPA-PSK is a security protocol that encrypts the data on a wireless network, securing communication through cryptographic means rather than obscurity.
- Storing the router in an obscure physical location may limit physical access to the device but does not impact the electronic or digital security measures of the network infrastructure itself.
