SEC501: Advanced Security Essentials - Enterprise Defender
A must for cyber security professionals!
This is the best technical training course I have ever taken. SEC501 exposed me to many valuable concepts and tools but also gave me a solid introduction to those tools so that I can continue to study and improve on my own.
Cyber security continues to be a critical area for organizations and will continue to increase in importance as attacks become stealthier, have a greater financial impact on an organization, and cause reputational damage. While Security Essentials lays a solid foundation for the security to engage the battle.
A key theme is that prevention is ideal, but detection is a must. We need to be able to ensure that we constantly improve our security to prevent as many attacks as possible. This prevention/protection occurs on two fronts - externally and internally. Attacks will continue to pose a threat to an organization as data becomes more portable and networks continue to be porous. Therefore a key focus needs to be on data protection, securing our critical information no matter whether it resides on a server, in a robust network architecture, or on a portable device.
Despite an organization's best effort at preventing attacks and protecting its critical data, some attacks will still be successful. Therefore we need to be able to detect attacks in a timely fashion. This is accomplished by understanding the traffic that is flowing on your networks and looking for indication of an attack. It also includes performing penetration testing and vulnerability analysis against an organization to identify problems and issues before a compromise occurs.
Finally, once an attack is detected we must react to it in a timely fashion and perform forensics. By understanding how the attacker broke in, this can be fed back into more effective and robust preventive and detective measures, completing the security lifecycle.
SEC501.1: Defensive Network Infrastructure
Mon Sep 16th, 2013
9:00 AM - 5:00 PM
Protecting a network from attack starts with designing, building, and implementing a robust network infrastructure. There are many aspects to implementing a defense-in-depth network that are often overlooked since companies focus too often only on functionality. Achieving the proper balance between business drivers and core protection of information is very difficult, and an organization must build a network that is mission resilient to a variety of attacks that might occur.
On the first day students will learn not only how to design and build a network that can both prevent attacks and recover after compromise, but also how to retrofit an existing network to achieve the level of protection that is required. Building a network is easy, but integrating all of the components so the network can withstand a variety of attacks and support the mission of the organization takes a special skill. Students will learn how to design and implement a functionality-rich, secure network and also how to maintain and update it as the threat landscape evolves.

SEC501.2: Packet Analysis
Tue Sep 17th, 2013
9:00 AM - 5:00 PM
Prevention is ideal, but detection is a must - this is a critical motto of security professionals. While organizations always like to prevent as many attacks as possible, some will still sneak into the network. In cases where an attack can not be prevented, security professionals must understand the indications and warnings that are indicative of attack and detect them before they cause significant harm. Packet analysis and intrusion detection is at the core of timely detection. Not only should attacks be detected, but organizations should react to make sure that these attacks can be prevented in the future.
Based on the changing landscape of attacks, detecting attacks is becoming more difficult because attacks are now more stealthy and difficult to find. Only by understanding the core principles of traffic analysis can one become a skilled analyst and be able to differ between normal traffic and attack traffic. In addition, new attacks are coming out all the time. So security professionals must be able to write rules that detect new, advanced zero-day attacks before they compromise a network.
In the past, traffic analysis and intrusion detection was treated as a separate discipline within many organizations. Today, prevention, detection, and reaction must all be closely knit so that once an attack is detected, defensive measures can be adapted, proactive forensics can be implemented, and the organization can to continue to operate.

Security is all about understanding, mitigating, and controlling risk to an organization's critical assets. Therefore an organization must understand what the changing threat landscape is and compare that against its own vulnerabilities that could be used to compromise a network. While this was never an easy task, it is becoming much more difficult since the threats are evolving very rapidly and organizations are so complex. On day three students will understand the variety of tests that can be run against an organization and how to perform penetration testing in an effective manner.
Finding basic vulnerabilities is easy, but it is not very effective if these are not the vulnerabilities that attackers will use to break into a system. Advanced penetration testing involves understanding the variety of systems and applications on a network and how they can be compromised by an attacker. Students will learn about both external and internal penetration testing and the methods of black, gray, and white box testing.
Penetration testing is critical to identify an organization's exposure points, but students will also learn how to prioritize and fix these vulnerabilities to increase the overall security of an organization.

SEC501.4: First Responder
Thu Sep 19th, 2013
9:00 AM - 5:00 PM
Any organizations that are connected to the Internet or that have employees are going to have attacks launched against them. Even with a keen focus on robust network design, preventive security, and finding vulnerabilities through penetration testing, some attacks will still occur. In these cases identifying, analyzing, and responding is critical.
Security professionals need to understand how to perform incident response, analyze what is occurring, and restore their organization back to a normal state as soon as possible. Day four will equip students with a proven six-step process to follow in response to an attack - prepare, identify, contain, eradicate, recover and learn from previous incidents. Cyber incidents are a lot like a fire. The sooner you detect them, the easier they are to deal with and the less damage they cause. Therefore prompt incident response is a key follow-on to intrusion analysis.
Another key aspect of incident response is forensic analysis and discovery. Students will learn how to perform forensic investigation and find indication of an attack. This information will be fed into the incident response process and ensure the attack is prevented from occurring again in the future.

As security professionals continue to build more proactive security measures, attackers methods will continue to evolve. A common way for attackers to target, control, and break into as many systems as possible is through the use of malware. Therefore, it is critical that students understand what type of malware is currently available to attackers and future trends and methods of exploiting systems. With this knowledge students can then learn how to analyze, defend, and detect malware on systems and minimize the impact to the organization.

SEC501.6: Data Loss Prevention
Sat Sep 21st, 2013
9:00 AM - 5:00 PM
Cyber security is all about managing, controlling, and mitigating risk to your critical assets. In almost every organization, your critical assets are composed of data or information. Whether it is a customer list, research plans, intellectual property, classified information, or a marketing plan, this data represents the life line of your organization and must be properly protected. Perimeters are still important and critical, but we are moving away from a fortress model and moving towards a focus on data. This is based primarily on the fact that our networks are becoming more porous, and our data is more portable.
Information no longer solely resides on your servers where properly configured access controls list can limit access and protect our information. The same intellectual property that is protected on a server behind a strong perimeter can now be copied to laptops (i.e. portable servers) and be plugged into networks (i.e. hotels, airports and coffee shops) that have no firewalls or security devices in place. This means the data must be able to be protected no matter where it resides, since a compromise of sensitive data will have an impact to the company, no matter how it was stolen.
Building a strong perimeter defense is a critical first step, but focusing in on protecting and controlling critical data from loss is another key step in building a strong preventive measure. Proactive security must be put in place to make sure critical information is properly protected and exposure is minimized.

It is always a thrill after I finish teaching SEC401 to see students leave with a fire in their eyes and an excitement about them. They walked into class feeling overwhelmed that security is a lost cause, but now they leave class understanding what they need to do and have a focus and drive to do the right thing to secure their organizations. However the next question we receive on a constant basis is, what course should I take next? How do I continue my journey? Well, it depends on what your focus area is. Do you want to get more into perimeter protection, IDS, operating system security, etc? The challenge is that many students have positions that do not allow them to focus on one area - they need to understand all of the key areas across security. What students are telling us is that they want a Security Essentials part 2 or a 500-level continuation of Security Essentials covering the next level of technical knowledge. In Security 501, SANS has decided to give students just what they have been asking for, and I am beyond thrilled with the results. We have identified core foundation areas that compliment SEC401 with no overlap and continue to build a solid security foundation for network practitioners.
This is illustrated by one student who after a recent class ran up to me, gave me a big hug (he was a retired football player, so I did not argue), and said, "SANS is awesome. I have been frustrated in my job for over a year and had lost hope that you really could secure an organization and that anything I did made a difference. Just as my light of hope was burning out, I decided to take the Security Essentials course, figuring it was a lost cause. After this class the fire is burning brighter than it ever was. I feel like a kid again and cannot wait to go back to my company and make a difference. However, I think my boss is scared because I called him eight times throughout the week, telling him all of the great information and practical knowledge I learned."
After teaching thousands of students, I am confident you will have similar results and be just as excited. However, just for reference, hugs are optional.
