We have one server, one network switch, and one storage device. We will assume that the server availability, the switch availability, and the storage availability are 95%, 90%, and 85%, respectively. The website will function normally only if the server, the switch, and the storage are all operational. That is, a failure of any individual hardware device would cause the website to be unavailable. What is the availability of the website?

On a specific mission, it was determined that the success of an attack to a given system would be only possible if at least one of the vulnerabilities get successfully exploited. After some initial simulations conducted on a network that is similar to the target the following probabilities of successful exploitation were:   - 30% of the time the IPs of the key components were captured   - 10% of the time the MACs of the key components were captured   - 40% of the time the Ports giving access to the target network were captured - 65% of the time the OS versions of the main components were obtained   - 50% of the time the key services needed for the attack were compromised   The attack would be deployed only if a breach was obtained within the allocated time frame. The mechanisms by which each of the above impacts the attack were also tested and proved to be independent on how they actuate. The experiments showed that knowing the IPs would allow a successful attack 25% of the time, while…

Task 1: Complete the following scenario assignments. Your work was so well received by Harry for the Game Stop that he asks you to create a small network from scratch as a demo of how to configure the entire network of machines. You have four machines and a hub you are connecting to each other and then the Internet as shown below. Complete the network configuration of IP addresses, default gateways, subnet, and network addresses and submit to your instructor.

Create me a topology and diagram of the answer of the problem below. Explain it detailed how it was get. The router Central, ISP cluster, and the Web server are completely configured. You must create a new IPv4 addressing scheme that will accommodate 4 subnets using the 192.168.0.0/24 network. The IT department requires 25 hosts. The Sales department needs 50 hosts. The subnet for the rest of the staff requires 100 hosts. A Guest subnet will be added in the future to accommodate 25 hosts.

Because of the central role that servers on a flat network play in the operation of a business, it is essential that they have a Network Security Design implemented to increase their level of protection and security. Because of how flat the network is, this is the situation. Whenever a demilitarized zone is set up, whenever that may be. What recommendations do you have for improving the present network architecture?

CRLs must be renewed whenever an older one is replaced since no new licenses have been granted during that time. Just why do you suppose that is the case?

Question 3. In a network-based intrusion detection system, two nodes A and B monitor inbound traffic. The two nodes are providing a central node C with alarm signals and C classifies the threat level based on this information. The alarm signals can be one of the four types P1, P2, P3, or P4. Assume that all four alarm signal types occur with equal probability. The classification carried out by C when receiving one signal from A and one from B at a given time is according to the following rule: Threat level Signal types One P1 signal + One P2 signal (a). (b). (c). Low Medium High Severe One P2 signal + One P3 signal One P3 signal + One P4 signal Two P4 signals generate. List all the possible pairs of alarm signals that A and B can Given that at least one of the two monitoring nodes gener- ates an alarm signal P3, what is the probability that C will classify the threat as "medium"? Justify your answer. Given that at least one of the two monitoring nodes gener- ates an alarm signal P4,…

Consider the following case study: Video OnDemand is a new subscription-based service for on-demand Internet streaming media. There are three types of users for Video On Demand: 1. Standard users; 2. Premium users; 3. Maintainers. Standard and Premium users are able to log in, renew their subscriptions, search and have access to the standard video library. In addition, Premier users have access to the latest release library. Maintainers are able to log in, add videos, modify user's subscriptions, search for any type of video, and read the audit log involving users' activities. An unregistered individual can obtain access to the system via an automatic procedure involving the payment of the subscription: such a procedure can be audited by maintainers. You are assigned to be part of the threat modelling team. You need to follow the main steps of the threat modelling process: Decompose the application using data flow diagrams. • Determine the threats to the system using the STRIDE model…
