The bridge can become deadlocked ifa westbound and an eastbound farmer get on the bridgeat the same time. (Oz farmers are stubborn and areunable to back up.)Complete the missing parts in the following pseudo-codethat uses semaphores to prevent dead-lock.semaphore ok_to_cross = 1 ;void enter_bridge () {ok_to_cross. down();}void exit_bridge () {ok_to_cross. up() ;}// Farmer Process :while (1) {enter_bridge();cross_bridge ();exit_bridge() ;}Is the solution above starvation-free? yes Answer 1:1Answer 2:down()Answer 3:up()Answer 4:enter_bridge()Answer 5:exit_bridge()Answer 6:yes

write a custom Snort rule to handle Inbound and Outbound HTTP traffic on the Private (Host-Only) network. Upload a screen shot of the Snort console displaying the alerts. In this exercise, we are going to create two Snort monitoring rules that will be used to alert on HTTPnetwork traffic for both Inbound and Outbound traffic. Remember, Inbound rules are those rules whosedestination is to your internal network (HOME_NET), outbound rules are directed out of your internalnetwork (!HOME_NET). When you use “any” there is no distinction on whether a rule is Inbound orOutbound. When using Inbound/Outbound to describe local traffic, traffic generated on the samenetwork (as in this lab on VMnet-1), the Inbound reference is to your client system that is running snortthe Outbound reference is to the HTTP server.You should now understand a little bit about custom rules, so given the following rule:alert tcp any any -> any 80 (msg:"TCP HTTP Testing Rule"; sid:1000004;)You should be able to…
