How can an organization ensure that only approved devices access its network?

1. Implement user education programs

2. Utilize MAC address filtering

3. Relax security protocols to improve accessibility

4. Increase bandwidth availability

The correct answer is: Utilize MAC address filtering

Utilizing MAC address filtering is an effective method for an organization to ensure that only approved devices access its network. This security feature allows network administrators to create a list of authorized MAC addresses, which are unique identifiers assigned to network interfaces for communication on the physical network segment. When a device attempts to connect to the network, its MAC address is checked against this list. If the address is found, access is granted; if not, the device is blocked. By implementing MAC address filtering, organizations can maintain a level of control over who can connect to their network, effectively preventing unauthorized devices from gaining access. However, it is important to note that while MAC address filtering adds a layer of security, it is not foolproof since MAC addresses can be spoofed. Therefore, it is typically used in conjunction with other security measures for a more comprehensive approach. User education programs can enhance overall security awareness among employees but do not specifically control device access to the network. Relaxing security protocols would undermine the organization's defenses and make it easier for unauthorized devices to gain access. Increasing bandwidth availability might improve performance but does not directly relate to device access control. Therefore, utilizing MAC address filtering stands out as the most direct and relevant method for ensuring that only authorized devices can connect to a
