Our course will show you how to prevent your organization's security problems from being headline news in the Wall Street Journal!
"Prevention is Ideal but Detection is a Must."
With the rise in advanced persistent threats, it is almost inevitable that organizations will be targeted. Whether the attacker is successful in penetrating an organization's network depends on the effectiveness of the organization's defense. Defending against attacks is an ongoing challenge, with new threats emerging all of the time, including the next generation of threats. Organizations need to understand what really works in cybersecurity. What has worked, and will always work, is taking a risk-based approach to cyber defense. Before your organization spends a dollar of its IT budget or allocates any resources or time to anything in the name of cybersecurity, three questions must be answered:
- What is the risk?
- Is it the highest priority risk?
- What is the most cost-effective way to reduce the risk?
Security is all about making sure you focus on the right areas of defense. In SEC401 you will learn the language and underlying theory of computer and information security. You will gain the essential and effective security knowledge you will need if you are given the responsibility for securing systems and/or organizations. This course meets both of the key promises SANS makes to our students: (1) You will learn up-to-the-minute skills you can put into practice immediately upon returning to work; and (2) You will be taught by the best security instructors in the industry.

Course Syllabus
SEC401.1: Network Security Essentials
Overview
A key way that attackers gain access to a company's resources is through a network connected to the Internet. A company wants to try to prevent as many attacks as possible, but in cases where it cannot prevent an attack, it must detect it in a timely manner. Therefore, an understanding and ability to create and identify the goals of building a defensible network architecture are critical. It is just as important to know and understand the architecture of the system, types of designs, communication flow and how to protect against attacks using devices such as routers and firewalls. These essentials, and more, will be covered during 401.1, in order to provide a firm foundation for the consecutive days of training.
By the end of the 401.1, you will understand Defensible Network Architecture, Virtualization and Cloud Security (Lab Virtual Machine Setup), Network Device Security, Networking and Protocols (Lab - tcpdump), Securing Wireless Networks (Lab - Aircrack-ng), Securing Web Communications (Lab -Wireshark). In any organization whether large or small all data is not created equal. Some data is routine and incidental while other information can be very sensitive, the loss of which could cause irreparable harm to an organization.
Understanding attacks, the vulnerability behind those attacks and how to prioritize the information and steps to secure the systems will be essential. Common attacks occur with web applications, authentication and other forms of communication. It is imperative to gain familiarity with protocols and techniques used to monitor, stop and even perform attacks against systems.

SEC401.2: Defense-In-Depth and Attacks
Overview
To secure an enterprise network, you must understand the general principles of network security. In 401.2, we look at threats to our systems and take a "big picture" look at how to defend against them. You will learn that protections need to be layered: a principle called defense-in-depth. We explain some principles that will serve you well in protecting your systems. You will also learn about key areas of network security.
The course starts with information assurance foundations. Students look at security threats, and how they have impacted confidentiality, integrity, and availability. The first half of the day also covers creating sound security policies and password management, including tools for password strength on both Unix and Windows platforms. The day draws to a close by looking at attack strategies and how the offense operates.
Students will understand to properly secure and defend a network, you must first have a clear and strong understanding of both the logical and physical components of an architecture. In security (and design), huge mistakes have been made because the security architect did not look at the system as a whole, but rather focused on a particular problem which weakened the overall analysis. It's always important to remember that analyzing the security of something as complex as a network is in itself a complex process.

SEC401.3: Threat Management
Overview
Whether targeting a specific system or just searching the Internet for an easy target, an attacker uses an arsenal of tools to automate finding new systems; mapping out networks; and probing for specific, exploitable vulnerabilities. This phase of an attack is called reconnaissance, and it can be launched by an attacker any amount of time before exploiting vulnerabilities and gaining access to systems and networks. In fact, evidence of reconnaissance activity can be a clue that a targeted attack is on the horizon.
Those in charge of system and network security cannot afford to be any less proficient in discovering and eliminating these vulnerabilities than the attackers are at finding and exploiting them. One strategy is to make full use of the very tools being used against you and to do it regularly. With security, proper visibility is critical. If you do not understand or know about vulnerabilities, this puts you at a disadvantage, especially based on the fact that the adversary is usually aware of these exposures. The more you know about your environment, the better you can protect it.
This module covers technology, tools, and techniques used for information gathering, network mapping, vulnerability scanning, and the management application of mapping, scanning technology, including exploitation. First, let's set the stage in terms of the management expectation of such a program. Second, we define threat vectors and common sources of reconnaissance on your systems. Then, we examine some of the classic probing tools and their impact. We then show you how to use your own tools to find vulnerabilities before the attackers do. Finally, we will show the basic steps of how to do a penetration test to verify and validate the security of your organization.

SEC401.4: Cryptography, Risk Management and Response
Overview
There is no silver bullet when it comes to security. However, there is one technology that would help solve a lot of security issues, though few companies deploy it correctly. This technology is cryptography. Concealing the meaning of a message can prevent unauthorized parties from reading sensitive information. Sec401.4 looks at various aspects of encryption and how it can be used to secure a company's assets. A related area called steganography, or information hiding, is also covered.
Cryptography, the science of secret writing, helps us communicate without revealing the meaning of information to adversaries. It also potentially validates to whom we are communicating. It can protect any kind of data, from very sensitive information, such as Internet-based commerce and banking transactions, to harmless messages you would prefer that no one else knew about, such as a letter to a friend. Cryptography (abbreviated as crypto) can provide a great deal of confidentiality and integrity checks for information. However, it is not a silver bullet, and it can lead to a tremendous false sense of security unless used properly and implemented correctly. Cryptography should always be a part of a larger defense-in-depth strategy, providing just one layer of the security onion.

Author Statement
"One of the things I love to hear from students after teaching Security 401 is 'I have worked in security for many years and after taking this course I realized how much I did not know.' With the latest version of Security Essentials and the Bootcamp, we have really captured the critical aspects of security and enhanced those topics with examples to drive home the key points. After you have attended Security 401, I am confident you will walk away with solutions to problems you have had for a while, plus solutions to problems you did not even know you had."
