Chapter 3 starts with the identification and the introduction of the Principles, and the characteristics of a successful IG program.  Identify these Principles, and provide a brief explanation of  their importance?

Q2: In order to have a successful IG program, one of the eight (8) Information Risk Planning and Management step is to develop metrics and measure results. Why are metrics required?  Briefly provide your explanation

 Short Newsletter Item: The Dangers of Biting on a Phish

Discussion Topic

Write a short “newsletter” article (3 to 5 paragraphs) for the non-technical managers and employees at Sifers-Grayson to explain the following:

(a) What is Phishing? (Focus on phishing emails and targeted attacks that include spear phishing and whaling.)

(b) What “bad things” can happen when a successful phishing attack gives outsiders access to company networks and computers?

(c) How can employees avoid “biting” on a “phish?”

(d) How should employees report phishing attacks? Why is immediate reporting critical to stopping the attackers?

Since this article is for a newsletter, you may use an informal but professional tone (address the reader as “you,” use “we” and “our” to refer to the organization’s perspective). The focus of the article should be upon changing how people think about and respond to computer security incidents. Humor is good but should not lessen the severity of the problem.

Provide in-text citations and references for 3 or more authoritative sources. Put the reference list at the end of your article.

Part 1: In a two-phase, total-ordermulticast system, messages are sent in the following sequence from node S to G1 and G2. G1 and G2 are the members of the group.

1. S sends m1 to G1
2. S sends m1 to G2
3. S sends m2 to G2
4. S sends m2 to G1

Use the basicimplementation of the Lamport clock. The clock s at each node start at: S: 4, G1: 6, G2: 1

Show the exchange of messages and their acknowledgmentsin a clock diagram using the basic implementation of Lamport’s clock.  

In which order and at what times are m1 and m2 delivered?

Part 2.Draw a state diagram of Maekawa’s voting algorithm on the slide “Maekawa’s algorithm” in the “Distributed mutual exclusion” slide set. Note that the state diagram is from the point of view of any oneof the nodes, called “this” node below. The state diagram cannot show the states of other nodes.

1. i) Start with the basic case where “this” node wants the lock, gets it, and then releases it, and no other node wants the lock at the same time. In this case, “this” node goes through all the states in this order:

Released and not voted
Wanted and not voted
Wanted and voted
Held and voted
Released and voted
(Back to) Released and not voted

Events are:

acquire for when “this” node wants the lock

releasefor when “this” node gives up the lock.

request_received, reply_received, and release_received when a message from any node arrives at “this” node.

The state diagram is similar the one of Ricart and Agrawala’s state machine (in the Distributed Mutual Exclusion PowerPoint deck) but has more states.

*** If you do parti) more or less correctly, you will earn most of the points.***

1. ii) The complete solution includes the situations where “this” node votes on requests from other nodes

This  week we discuss computer forensics.  Computer forensics is the  discovery process necessary to gather data from an electronic device.   Encryption has become so strong that it is virtually impossible for law  enforcement to decrypt data.  Law enforcement seeks methods to decrypt  data that has been encrypted.  It is much easier to acquire the password  from the user or some other source than it is to try to guess a  password.  iOS and Android both have features which will “brick” a phone  should too many attempts to guess the password occur.  The question is  why isn’t biometrics a safe method to encrypt data in the face of law  enforcement efforts to acquire that password.  Also, if you use a  password that must be typed in, can law enforcement force you to enter  the password so that they can read the data on a computing device?

Answer  the question with a short paragraph, between 150 and 250 words.   Brevity is a virtue.  That is why you are limited to 250 words.  If you  can’t present your hypothesis in 250 words or less then it is too  complicated.   Remember that when you state a fact if you don’t provide a  reference, it is not a fact but rather an opinion.
