Course Content
Module 1: Introduction to Designing Security
A security design is a comprehensive plan that guides the implementation of security policies and procedures for an organization. A security design helps an organization to organize its assets to implement security in a consistent and effective manner.
This module describes the basic framework for designing network security and introduces key concepts used throughout the course. It also introduces a fictional organization which the labs in the course use as an ongoing case study.

Module 3: Identifying Threats to Network Security
Without security measures and controls in place, your data may be subjected to an attack. Some attacks are passive, which means that information is monitored; others are active, which means that the information is altered with intent to corrupt or destroy the data or the network itself.
Your networks and data are vulnerable to any of these types of attacks if you do not have a security plan in place.
In this module, you will learn how to identify possible threats to a network and understand common motivations of attackers. The module introduces the STRIDE (Spoofing, Tampering, Repudiation, Information disclosure, Denial of service, Elevation of privilege) threat model as an effective way to predict where threats may occur in an organization.

Module 4: Analyzing Security Risks
Many organizations cannot react to new security threats before their business is affected. Managing the security of their infrastructuresand the business value that those infrastructures deliverhas become a primary concern for information technology (IT) departments.
The Microsoft approach to security risk management is proactive and can assist organizations of all sizes with their response to the requirements presented by these environmental and legal challenges. A formal security risk management process enables enterprises to operate in the most cost-efficient manner by adopting a known and acceptable level of business risk. It also gives organizations a consistent, clear path to organize and prioritize limited resources in order to manage risk.
In this module, you will learn how to determine what resources in your organization require protection and how to prioritize those resources based on their value. You will then develop a risk management plan, based on the MOF risk model, to identify and analyze risks proactively and to determine an appropriate level of protection for each resource.

Module 7: Designing Security for Accounts and Services
Computer networks use accounts to grant users, applications, and network services access to the information on a network. Network services are server applications that are usually hosted on dedicated server computers.
If an attacker gains access to an account that has excessive privileges, or breaks the password that is associated with an account, the attacker can obtain authorized access to a network.
Windows services are executable programs that run in sessions outside the session that the user who is currently logged on is using. In this way, services run in the background, independent of any user session. Services can start automatically when the computer starts, and can also be paused and restarted. Services may not show a user interface, although they typically communicate with a user interface to control and administer the service. Because of this behavior, services are ideal for use on a server or whenever you require long-term functionality that does not interfere with other users who are working on the same computer. In addition to services that Microsoft has created, many third-party vendors design products to be deployed as services running continuously in the background. Antivirus services are an example of this type of product.
In this module, you will learn how to determine threats and analyze risks to accounts and services in an organization. You will also learn how to design security for accounts and services, including determining security requirements, creating policies, and designing strategies to manage security.

Module 9: Designing Security for Data
Business data is one of the most valuable resources in many organizations. If data were to be irreparably damaged, lost, or exposed to competitors, many organizations would be adversely affected and perhaps even driven out of business. For client hosts, protecting data can be particularly daunting because portable computers can be stolen from mobile users, and backing up data for mobile users is very difficult. Protecting data that is stored on servers is still a significant challenge, but for most organizations it is one that is achievable. For these reasons, many companies require their end users to store their critical data on servers managed by their information technology (IT) department. Data can be protected through the use of access control lists (ACLs) on files and folders, by using encryption, and by using an effective backup and restore strategy.
In this module, you will learn how to determine threats and analyze risks to data in an organization. You will learn how to design an access control model for files and folders in order to protect data that is stored on network servers. You will also learn about considerations for encrypting and managing data.

Module 11: Designing Security for Network Perimeters
Properly configured firewalls and border routers are the cornerstone of perimeter security. However, all of these devices must be properly secured because the entire network is put at risk when any one of them is compromised. Organizations must therefore invest time and resources in securing not only the Virtual Private Network (VPN) servers and the remote access servers (RAS), but also the mobile computers that are used to connect to those servers. To do business on and through the Internet, organizations must make some of their business applications and data accessible through the Internet. Traditional packet-filtering firewalls block network ports and computer addresses, but ports must be opened for the business applications. This means that your organization requires firewalls or proxy servers that are application-aware and capable of filtering network traffic at the application layer.
In this module, you will learn how to determine threats and analyze risks to network perimeters. You will also learn how to design security for network perimeters, including perimeter networks (also known as DMZs, demilitarized zones, and screened subnets), and for computers that connect directly to the Internet.

Module 12: Responding to Security Incidents
Network security for an organization is an exercise in prevention. A good security design that is properly implemented will prevent most of the most common attacks. However, it is very likely that an attacker will eventually penetrate the defenses that you design.
When an attack happens, the key to limiting damage is early detection and a rapid and orderly response. Auditing is an important tool to help you to detect network abnormalities that may indicate attacks. An incident response procedure is a series of steps that you design in advance to guide your organization during a security incident.
