So the answer to what is MAC address spoofing is very simple as it means a method for changing or masking the factory-assigned MAC address of a network interface on a device. Spoofing in general means the diverse methods available to control and operate the fundamental address system in different computer networks. One of the most important strategies used in MAC spoofing attacks is to mask the MAC address, also popularly known as MAC ID spoofing. MAC address spoofing is which type of attack wherein the hacker is also able to bypass authentication checks as he presents this as the default gateway and copies all of the data passed on to the default gateway without being identified, giving him all the important details about applications in use and end-host IP addresses. MAC address spoofing attack is where the impostor or hacker hunts the network for valid and original MAC addresses and circumvents access control measures, giving the hacker the advantage to pose as one of the valid MAC addresses. But first, we need to understand what a MAC spoofing attack is in order to prevent ourselves from falling victims to it.
MAC spoofing attack is a common phenomenon currently, thanks to the ever-growing technology.

However, masking the MAC address on the software side is possible and this is how MAC spoofing works. This MAC address is virtually burned to the hardware by the vendor and hence the end-user cannot alter or rewrite this burned–in address (BIA). Let us learn more about mac spoofing attack.Īn IP address is used to recognize where you are on the Internet and the MAC address is used to recognize what device is on the local network. MAC address includes 48 bits, or 6 bytes, and takes the subsequent format: ‘XX:XX:XX:YY:YY: YY’. This address is used to recognize the communications of the network interface on every local network. In simpler words, it is the exclusive, worldwide physical identification number given to every device that is connected to a network interface, be it wired or wireless.

He is currently the director of operations for the Southern Theater Network Operations and Security Center. Secret Service and the Defense Information Systems Agency. Mike Mullins has served as an assistant network administrator and a network security administrator for the U.S. If you haven't implemented this action (especially for your children), I suggest you do so today. In addition, keep in mind that these restrictions will not force a logoff - they only enforce logon time.Ĭontrolling access to the machines you own and the Internet you pay for is easy once you know how. You can use the abbreviation for the day (i.e., M,T,W,Th,F,Sa,Su). If you make a mistake for an account or want to start over, you can always clear the restriction with this command: net user Sister /time:all Note: The system limits time to one-hour increments, which means you can only restrict the user on the hour (e.g., 13:00 or 1pm, not 13:30 or 1:30pm). These two commands set account restrictions for weekday and weekend logon for both accounts. Type the following command, and press : net user Sister /time: M-Th,4pm-9pm F-Su,8am-9pm What if you want to set different restrictions for different users? For example, in our sample family, Sister is older, so we want to let her access the computer a little later.
Keeping the command prompt with the displayed accounts open, we'll start adding time restrictions for Junior. Using this list as an example, let's say we've decided to restrict access to the computer (and the Internet) for Junior and Sister. Here's an example of what it might look like: Administrator ASPNET Dad This displays a list of accounts on the machine. Go to Start | Run, type cmd, and click OK.
