CHAPTER 1 REVIEW
End of Chapter 1Exam Essentials – if you are gathering information to
review as a comparison to the CompTIA test domain content
Hands-on Labs – not a graded item. This section reminds us to keep our systems up to date. Microsoft’s second Tuesday updates, security vendor’s virus file update (daily), etc.
Review Questions with the answers after – use these to study concepts

Chapter 2 - Identifying Potential RisksWhat is a risk? WASHINGTON, Feb 7, 2011 -- Cyberspies have penetrated the U.S. electrical grid and
left behind software programs that could be used to disrupt the system, according to current and former national-security officials. The spies came from China, Russia and other countries, these officials said, and were believed to be on a mission to navigate the U.S. electrical system and its controls. Wall Street Journal
What is an attack? Attack - when an unauthorized individual or group attempts to
access, modify or damage systems or environment.
Attacks Strategies – the bad guys have one or more of these goals:1. Access attack – access to resources2. Modification or repudiation attack – modify information3. Denial-of-service attack – disrupt the network, denying users access

Types of Attacks
Access attack – someone who should not be able to wants to access your resources
Eavesdropping, snooping, interceptionModification and repudiation attack – someone wants to modify information in your systems
Change grades, fraudulent transactions,Denial of Service (DoS) attack – an attempt to disrupt your network and services

CHAPTER 2
Understanding OVAL
Open Vulnerability and Assessment Languagehttp://oval.mitre.org
OVAL is an information security community effort to standardize how to assess and report upon the machine state of computer systems. OVAL includes a language to encode system details, and an assortment of content repositories held throughout the community.
A community written standard in XML to promote open and publicly available security contentConsists of:
A languageAn interpreterA repository

CHAPTER 2
Social Engineering
Social engineering is a process where an attacker attempts to acquire information about your network and system by talking to people in the organization.
Preys on the trusting nature of people to breach security.
Can be prevented through training and standard security policies.

Auditing Processes and Files

UNIT 2
Unit 2 AssignmentUnit Two Project 1. Perform a web search using your favorite search engine (yahoo.com, google.com, etc) on some of the most popular methods used to implement the various attacks discussed in Chapter 2. Then, discuss ways to prevent these attacks or at least minimize their effects on your organization.
2. Security topology covers four primary areas of concern (design goals, security zones, technologies, and business requirements). Describe each area including key topics in each area.
3. Discuss software threats classified as malicious code on page 81 of your text.
CHAPTER 2
Clarification of Question 1 on Unit 2 Project
From the Project Rubric: For example, look for the methods used to start a Denial of Service (DoS) attack like which software is used, the motives behind DoS, etc. Then, discuss ways to prevent these attacks or at least minimize their effects on your organization.
There are attack types from page 54 through 63. Don’t just discuss DoS, there are various types listed.
