The simplest method of filtering traffic is to use a firewall to block certain ports or IP addresses. This can help to prevent unauthorized access to your network and reduce the risk of security breaches. It is also important to regularly update your firewall rules to stay protected against emerging threats.
MAC filtering
Network Layer
Adding a password should do the trick. You can also add MAC filtering, if your router supports this feature. When MAC filtering is enabled, only computers/devices specified in White list can access your network.
A computer on a network that acts as the central storage location for programs and data used on a network is a server.
A computer on a network that acts as the central storage location for programs and data used on a network is a server.
If you computer and network is not protected, then yes, there is that possibility.
Your home internet and network should be protected by a password to stop identity theft.
They prevent specified types of traffic from reaching specified network destinations.
MAC filtering
MAC Filtering
MAC filtering takes network security to the next level by only granting access to specific network cards.A MAC (media access control) address is a unique identifier for a network card; no two cards have the same MAC address, so it functions like a fingerprint - even a wireless card and an Ethernet card built-in to the same laptop won't have the same MAC address. Therefore, MAC address filtering adds security by only allowing network cards with the right "fingerprint" to access the network.However, it should be noted that MAC address filtering is not a strong form of security. MAC addresses are extremely easy to "spoof" - that is, it's easy to fake the address of a legitimate network card. If an attacker is able to identify the MAC address of a permitted network card, they can masquerade as the legit card. Therefore, MAC address filtering is not a replacement for using encryption. MAC address filtering can help security if used in an environment running WPA.
