<span>Password procedures, information encryption software, and firewalls are examples of measures taken to address are all measures taken to safeguard information security and protect users data from being tampered or manipulated by invaders.
In web, if we leave our information without encryption or if we leave our system without firewall, different types of security threats might arise: such as, information being hacked, manipulated or sent to wrong places. To avoid this information encryption is done. We might also need to firewall our system so that we can avoid unwanted access and invading of our privacy using malwares and other tools. </span>
Answer:
Blocking Mode
Explanation:
Spanning Tree Protocol is used to allow path redundancy in the network without creating cycles/circles also called loops.
When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
This affects the performance of the network as the result of broadcast packets flooding.
STP puts one port of the switch to forwarding mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to blocking mode and the one port that is left after this is placed in forward mode.
Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
This information helps STP to eliminate the redundant paths.
So this is how STP allows only one active path to the destination while blocking all other paths to avoid switching loop.

Answer:
While selecting the access control system (software or hardware), there are many factors that influence it and those factors are campus location, network capabilities, number of users using it, size of campus, the motive for using it, etc.
Explanation:
The access control system is electronic device that needs to be connected to the network for providing security control and authorization to the user to enter into the Campus.
Access control systems are used to control access into premises or any IT area which is control in two ways either in a physical way or a logical way.
