Chapter 6, Problem 1RQ
Explanation of Solution
Firewall:
A firewall is security software which imposes a set of protocols to prevent specific types of data from moving among trusted and untrusted level of networks.
Trusted network and untrusted network:
The untrusted network is the common Internet or another part of public network, while the trusted network is usually a privately owned network or organization’s network.
Relationship among Firewall, trusted network and untrusted network:
- The relationship is that information is only restricted by firewall via particular spaces called “ports”.
- Firewall prevents the untrusted or unwanted network connections from outside, and filters it to the trusted network which lies on the bounds of the firewall to ensure that it’s legitimate.

- A controller is required for a home security alarm, providing the followingfunctionality. The alarm does nothing while it is disarmed (‘switched off’). It canbe armed (‘switched on’) by entering a PIN on the keypad. Whenever thealarm is armed, it can be disarmed by entering the PIN on the keypad.If motion is detected while the alarm is armed, the siren should sound AND asingle SMS message sent to the police to notify them. Further motion shouldnot result in more messages being sent. If the siren is sounding, it can only bedisarmed by entering the PIN on the keypad. Once the alarm is disarmed, asingle SMS should be sent to the police to notify them.Two (active-high) input signals are provided to the controller:MOTION: Asserted while motion is detected inside the home.PIN: Asserted for a single clock cycle whenever the PIN has beencorrectly entered on the keypad.The controller must provide two (active-high) outputs:SIREN: The siren sounds while this output is asserted.POLICE: One SMS…arrow_forward4G+ Vo) % 1.1.
