Answer:
enable the used ports in the router with their respective IP address and only the connected ports in the switch. Allow configure the STP on the switch
Explanation:
Network switches are used to connect a group of computer devices in a network LAN. It is automatically enabled when a port is connected and creates a MAC address table of the computers connected to it. STP or spanning-tree protocol is a protocol used to prevent looping in a switch. Unused ports can be disabled for security reasons.
A router is a network device that is used to forward packets between networks. All used ports in a router must be enabled and configured with an IP address and subnet mask.
Answer:
Given:
Passwords are selected from 4 characters.
Character combinations are 26 lower case alphabetic characters.
Passwords attempts by adversary is at rate of 1 second.
To find:
Expected time to discover the correct password
Explanation:
Solution:
4 character combinations of 26 alphabetic characters at the rate of one attempt at every 1 second = 26 * 4 = 104
So 104 seconds is the time to discover the correct password. However this is the worst case scenario when adversary has to go through every possible combination. An average time or expected time to discover the correct password is:
13 * 4 = 52
You can also write it as 104 / 2 = 52 to discover the correct password. This is when at least half of the password attempts seem to be correct.
