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:
It is called a WPS brutal force attack.
Explanation:
Wired and wireless networks are both susceptible to attacks. The wired network, the advantage as a cable connection, is more secure than wireless networks, but wireless network also have security measures like the wifi protected set up (WPS).
WPS is used to connect to a network without passphrase, but with a key combination or a PIN.
Brutal force attacks are used on WPS to forcefully generate the PIN, using a third party software.
Use the following rules:
- The sum of currents that enter and exit a node (junction) is always zero. So if you have 3 wires that connect, through one flows 2A, the other 3A, then the third must deliver 5A (taking the direction into account!)
- The sum of voltages across different components should always add up. So if you have a battery of 10V with two unknown resistors, and over one of the resistors is 4V, you know the other one has the remaining 6V.
- With resistors, V=I*R must hold.
With these basic rules you should get a long way!
The development of new information system is economically justified when or if the organization or group handling the information system has assessed its cost feasibility. If so, this will only fall under the circumstances that the information system is justified economically
