Mark Baggett

Mark Baggett

Mark Baggett's first foray into information security was on the receiving end of hacking, and he was amazed by the experience. "The hackers made my computer do stuff that I didn't think was possible," he says. "It was like magic and I had to know how the trick was done." He immediately became obsessed with understanding all the tricks, how they worked, and how to prevent them from happening again.

Fast forward to today and Mark's infosec career spans nearly 30 years with 15 of those years spent teaching for SANS. Mark is currently a senior instructor for SANS and an independent consultant through his company Indepth Defense providing forensics, incident response, and penetration testing services. Mark has also served as the technical advisor to the DoD for SANS since 2011, where he assists various government organizations in the development of information security capabilities.

Mark still finds information security as fun as the first day he discovered it, and feels that learning about information security should be fun too. "I really want the students to enjoy their classroom experience and look forward to learning skills that will make them more effective information security professionals," he says. And Mark stays busy in the SANS classroom teaching SEC573: Automating Information Security with Python; SEC560: Network Penetration Testing and Ethical Hacking; SEC504: Hacker Tools, Techniques, Exploits, and Incident Handling; and The Essentials of Automating Information Security with Python.

As an instructor, Mark's enjoyment of information security is infectious and his favorite moments are when students solve complex problems they thought were beyond their capability at the beginning of the week. "When students learn how to code and how to apply it to their day jobs it changes their lives forever," he says.

"It is my goal to meet the student where his or her current skill level is and move them forward," says Mark, noting that his most successful students are those who are honest about where their skills are and willing to put in the work to improve. "I'll promise to give them the resources and assistance they need in a way that is both entertaining and judgement-free."

Mark recalls a recent interaction with an SEC573 student that demonstrates the growth potential SANS courses provide. "A student came up to me in class and shared that he had taken 4 years of college courses and 4 months of military training, and he hated programming and really wasn't looking forward to sitting in SEC573 for a week with me," recalls Mark. "But after only four days I had changed his mind about programming. It was fun! He was enjoying the challenges instead of dreading them and said he'd learned more about how to actually use his skills in real world scenarios in 4 days than in all those years of prior training."

Mark sees information security as the evolution of information technology challenges, moving from making computers do what they're supposed to do to getting computers to do what they aren't supposed to do. Something that requires constant learning. "Hacker techniques are constantly changing and in a few cases evolving. When I stop learning, I stop being effective," says Mark.

One of Mark's most challenging and fulfilling roles was working as the chief information security officer for a midsized media company. "I've always been committed to maintaining a high level of technical proficiency and expertise. Being able to use that in an executive position while leading a talented team, educating my peers on the board, setting strategy, and working to secure the organization was extremely challenging but very fulfilling."

Mark has a master's degree in information security engineering and is the 15th person in the world to receive the prestigious GIAC Security Expert certification (GSE). He also holds GPYC, GXPN, GPEN, GCIA, GCIH, GSEC, GWAPT, and GCPM certifications.

An active participant in the information security community, Mark is the founding president of The Greater Augusta Information Systems Security Association (ISSA) chapter which has been extremely successful in bringing networking and educational opportunities to Augusta information technology workers. He's also co-founder of the BSidesAugusta Information Security Conference, and has written a number of articles on information security topics.

Alissa Torres

Alissa Torres

Alissa Torres is an explorer at heart. Uncovering the full story of an attacker's exploits requires digging into known and unknown forensic artifacts, and this excavation is exactly what intrigues her. With more than 15 years of experience in computer and network security spanning government, academic, and corporate environments, Alissa has the deep experience and technical savvy to take on even the most difficult computer forensics challenges that come her way. Her current role as an Incident Response Manager at Cargill provides daily challenges "in the trenches" and demands constant technical growth. Alissa is also founder of her own firm, Sibertor Forensics, and has taught internationally in more than 10 countries.

Memory forensics is a bleeding-edge field of Digital Forensics & Incident Response (DFIR), and Alissa is the lead author as well as an instructor of FOR526: Memory Forensics In-Depth and co-author of the SANS Memory Forensics Poster. She also teaches  FOR500: Windows Forensic Analysis; FOR508: Advanced Digital Forensics, Incident Response, and Threat Hunting; and SEC504: Hacker Tools, Techniques, Exploits and Incident Handling.

Alissa was introduced to digital forensics during her four years of service in the U.S. Marine Corps. She moved on to various technical roles at KEYW Corporation, Northrop Grumman Information Systems, and as part of Mandiant's computer incident response team (MCIRT). Alissa has worked as an instructor at the U.S. Cyber Challenge Camps and at the Defense Cyber Investigations Training Academy (DCITA), delivering incident response and network basics to security professionals entering the forensics community. She is passionate about sharing knowledge, presenting annually at regional and national industry conferences and encouraging women's participation in science, technology, engineering, and math through regional outreach programs.

As both an investigator and instructor, Alissa has a constant and infectious desire to always learn more and question everything, an ethos embodied in the SANS DFIR classes. "Our curriculum ensures students gain an understanding of why an artifact matters and how the tools interpret the data." Alissa explains. An inquisitive nature can be the determining factor in investigative success, as Alissa learned when she identified a critical error in one of her team's web proxy timeline procedures. This discovery allowed for the correction of contractual fraud investigations involving the U.S.  government.  Sharing personal success stories like this one gives students real-world applications for the material they are learning and inspires them to evaluate and optimize their own investigative processes, whether in incident response, digital forensic investigations, or internal offensive reconnaissance.

As attackers learn how forensic investigators work, they become increasingly more sophisticated at leaving fewer traces behind. "We are in an arms race where the key difference is training," says Alissa. Toward that end, she encourages her students to ask more questions, grow the common body of knowledge, and make a difference in the digital forensics community. Her teaching style is best described as a type of "exposure therapy" that introduces concepts but then pushes students to get behind the keyboard and apply these concepts themselves.

Alissa's true passion is memory forensics, a rapidly evolving area of expertise for both attackers and defenders. As malware strives for a minimal footprint on the host, the battlefield exists in system memory. Alissa's students take the skills taught in FOR526 and move their investigations forward, in some cases even uncovering new details in their cases before the week-long class ends.

Alissa has a B.S from the University of Virginia and a M.S. in information technology from the University of Maryland. She is a GIAC Certified Forensic Analyst (GCFA), and holds the GCFE, GCIH, GSEC, CISSP, and EnCE certifications. Alissa has served as a member of the GIAC Advisory Board since 2013 and was recognized by SC Magazine as one of its "2016 Women to Watch." Needless to say, she stays pretty busy. When not enmeshed in metadata and memory structures, Alissa catches every soccer game she can, cheering at her kids' games and scheming to attend matches of her favorite team, Everton. In what time she has left from constant cybersecurity vigilance, Alissa enjoys hiking in the Puerto Rican rain forest and scaling rocks at Big Sur.

Matthew Toussain

Matthew Toussain

When he gets the chance, Matthew Toussain loves to take on an offbeat challenge. He's turned a closet into a server room, a table into a computer and a '76 Mustang into an electric car. He's also built an Alexa-enabled home entertainment system out of a car amp, a Raspberry Pi, a computer power supply unit, sheet metal, and plexiglass. It's that ingenuity that underscores his work as a certified SANS instructor.

Matthew has been a SANS instructor since 2016, and the inspiration that brought him here actually came from another instructor. "A SANS instructor changed my destiny," says Matthew. "The opportunity to have that kind of elemental impact on a newcomer's information security journey is singular, rare, and profound. I'm just glad for the chance to take part."

Since graduating from the U.S. Air Force Academy in 2012 with a B.S. in computer science, he has served as the senior cyber tactics development lead for the U.S. Air Force (USAF) and worked as a security analyst for Black Hills Information Security. In 2014, he started Open Security, which performs full-spectrum vulnerability risk assessments. 

His experience outside the classroom has given him opportunities to work on initiatives designed to protect people from terrorism. "I had a small part in national cyber defense. Specifically, after the Paris bombings on Nov. 13, 2015, I worked on programs designed to provide some additional early warning in the event of similar orchestrated attacks in the future."

For SANS, Matthew teaches SEC460: Enterprise Threat and Vulnerability Assessment and SEC560: Network Penetration Testing and Ethical Hacking. He worked with other SANS instructors to develop SEC460, Enterprise Threat and Vulnerability Assessment. Of the new course, Matthew writes, "Because SEC460 is a foundational course in the SANS penetration testing curriculum, it is itself a herald and a promise. For some newcomers, the first adventure with SANS is the spark of awakening for their inner hacker. It acts as a catalyst facilitating personal evolution and even genesis of a lifelong passion. The course authors, Adrien de Beaupre, Tim Medin, and myself, have meticulously crafted the SEC460 challenge to be a formative experience, attainable by all yet elementary to none."

An avid runner who also plays piano, guitar and violin, Matthew lives in Texas with a multitude of Cisco switches. In addition to teaching at SANS, he is an avid supporter of cyber competitions and participates as a red team member or mentor for the Collegiate Cyber Defense Competition (CCDC), the annual NSA-led event Cybersecurity Defense Exercise (CDX), and SANS Institute"s NetWars.

Jake Williams

Jake Williams

When a complex cyber attack put a private equity investment of more than $700 million on hold, the stakes couldn't have been higher. But that's exactly the kind of challenge that motivates Jake Williams, a computer science and information security expert, U.S. Army veteran, certified SANS instructor and co-author of FOR526: Memory Forensics In-Depth and FOR578: Cyber Threat Intelligence. To help mitigate the attack, Jake plied his information security expertise, discovered that not one but three different attackers had compromised the firm's network, and went about countering their moves.

Jake relishes the idea of meeting adversaries on the cyber battlefield. "I went into this field because I wanted a challenge," he says. "Infosec is like a game of chess to me. The attacker plays their moves and you play yours."

Jake started his information security career doing classified work with the U.S. government and was awarded the National Security Agency (NSA) Exceptional Civilian Service Award, which is given to fewer than 20 people annually. "I am immensely proud of the things I've accomplished," Jake says. "I'm positive the world is a safer place because of my work."

Today, Jake runs a successful Infosec consultancy. He's been involved in high-profile public sector cases including the malware analysis for the 2015 cyber attack on the Ukraine power grid. He's also tackled a variety of cases in the private sector. In one, Jake discovered attackers compromising a custom service the client had distributed to all its endpoints. Leveraging experience and insight with advanced persistent threats helped Jake "think like the attacker" and determine the attacker's likely hiding spots.

Jake's work has led to his invention of DropSmack, a proof-of-concept tool for highlighting the danger that cloud-based file sharing services pose to corporate networks, and the creation of ADD (Attention Deficit Disorder), a publicly-available memory anti-forensics toolkit.

Jake's work also led him to teaching. "I chose to be a SANS instructor because they are the very best in the business. Others talk about being the best, but SANS actually is the best," he says. "I love teaching people, but it goes beyond teaching for me. With many students, I'm making lasting professional relationships. Students come back again and again and have a lifelong learning relationship with SANS." 

Jake teaches a variety of classes (SEC503, SEC504, SEC660, SEC760, FOR508, FOR526, FOR578, FOR610) and prefers an active learning approach, using demos rather than slides to teach lessons. "It takes me back to my first exploits and I get the chance to relive that magical feeling all over again," he explains.

More importantly, Jake wants students to walk out of class being able to critically analyze a problem, discover a solution, and do something they couldn't do before. "I don't teach button-clicking steps, my goal is to ensure students understand how to take concepts from the class and apply them to their own cases and engagements."

Given his accomplishments, it should come as no surprise that Jake lives, sleeps, and breathes Infosec. When he's not teaching, he's consulting. He's a regular speaker at industry conferences including DC3, BSides (including BSides Las Vegas), DEFCON, Blackhat, Shmoocon, EnFuse, ISSA Summits, ISACA Summits, SANS Summits, and Distributech.  He has also presented security topics to a number of Fortune 100 executives.

Jake is also a two-time victor at the annual DC3 Digital Forensics Challenge. He drew on his passion for hands-on capture-the-flag events to design the critically acclaimed NetWars challenges for the SANS malware reversing and memory forensics courses.

Here is a SANS Summit presentation by Jake Williams:

Joshua Wright

Joshua Wright

Rogue hacker-turned-infosec-professional, Joshua Wright initially got into the infosec field after getting caught hacking, uncovering a vulnerability disclosure in the process. With the threat of a lawsuit looming, Joshua decided to pursue good over evil, launching his infosec career in 1997 with Johnson & Wales University. Since then, he's worked at five companies and today serves as director and senior security analyst for CounterHack, a company devoted to the development of information security challenges for education, evaluation, and competition.

Through his experiences as a penetration tester, Joshua has worked with hundreds of organizations on attacking and defending mobile devices and wireless systems, ethically disclosing significant product and protocol security weaknesses to well-known organizations.

A hacker at heart, Joshua admits that his current role is his most interesting job so far because he gets the chance to hack into credit card processing systems, gambling casinos, and smart shower systems to learn the mistakes developers and system designers make and figure out how to exploit them. He also loves the thrill of developing the annual Holiday Hack Challenge, which gives him the chance to add new and exciting challenges that refect modern technology while appealing to a wide audience of players of different ages and experience levels.

In 2003, Joshua also began teaching for SANS as a way to combine his interests in hacking and teaching. Today, as author of SEC504: Hacker Tools, Techniques, Exploits, and Incident Handling and instructor of SEC575: Mobile Device Security and Ethical Hacking, Joshua turns his experience hacking into customer networks into real-world case studies that students can relate to. "I really enjoy seeing my students make mistakes, realize the mistake, and immediately benefit from the realization," he says.

One of Joshua's favorite student interactions was working with a blind student who never let his physical challenges hold him back from achieving great things. He's found that his most successful students in the classroom are "those who push themselves to struggle and stumble, then recover and accomplish new goals with my support."
