Chapter: Web Security and Privacy: An American Perspective

Quote:

A system that maintains availability while under attack exhibits survivability. System with survivability exhibit degradation in the face of attacks. An example of an incident that that illustrates survivability is the Morris worm incident, where the internet slowly lost the ability to provide service but was never completely destroyed.

What I expect to learn:

To know the methods of securing information in the Web

Review:                    

I recently created an account in a website called “plurk”. Plurk is a free social networking and micro-blogging service that allows users to send updates (otherwise known as plurks) through short messages or links, which can be up to 140 text characters in length.

Updates are then shown on the user's home page using a timeline which lists all the updates received in chronological order, and delivered to other users who have signed up to receive them. Users can respond to other users' updates from their timeline through the Plurk.com website, by instant messaging, or by text messaging.

Now I know why my classmates are getting into plurk too much and it is because plurk allows people to know what their friend, their crush and even their professors are doing in every hour of every day. It is like, the more you inform people of your current physical ,emotional, and even spiritual status, the more they get attached to you and the larger your network gets. The more informed people gets, the more interested and curious they are of you as a person. I am not saying that this allows me to become exposed but it just helps people understand me more as a person, a student and a friend because of my status. It allows them to understand me and at the same time know what I am doing and what keeps me busy like I can just put there, “Currently typing my review for itethic” – see how detailed and brief you can be without giving too much.

What I learned:

·         Access Control List

·         Definition of security

·         Definition of integrity

·         Availability

·         Private key encryption

·         A replay attack

·         Simple replay attacks fall with public key cryptography

·         Browsing information

·         Provided technical services

·         Browser client connects

·         Definition of the following:

o    ISP

o    IP

o    DNS

o    Web proxy

o    Legal Issues and Societal Implications

o    Web activities

Integrative Questions:            

1.    What does ISP mean?

2.    What does IP mean?

3.    What does DNS mean?

4.    Enumerate the legal issues and societal implications in the web.

5.    What is private key encryption?
