Adversary simulation is a key component of a mature security program. Without it organizations might not truly understand their weaknesses until they face a real world adversary. This talk will promote the concept of the “Assumed Breach” model and discuss some steps security program owners can take to validate a security program is effective.

- 6. What are its origins?
- 7. • Originated in the 1960’s military war-game exercises • “Red” = the soviet union • 1963 - First public / documented example was a red team exercise structured around procuring a long range bomber. • Most early examples are structured around determining Soviet Unions capability

- 13. Unified Vision ‘01 & Millennium Challenge ‘02 • Millennium challenge ’02 • Red Cell Is highly restricted in its actions • Red Cell pre-emptively attacks US navy fleet with all of their air and sea resources sinking 21 Navy Vessels • White Cell “refloats” sunken navy vessels • Unified Vision ’01 • White Cell informs Red Cell that Blue Team has destroyed all of their 21 hidden ballistic missile silos • Blue Team commander never actually new the location of any of the 21 silos
- 14. What happens when we succeed?
- 15. RedTeam Success Stories • New York Marathon, NYPD and New York Roadrunners • Cover scenarios like: • How do you identify tainted water sources • How to respond if drones show up in specific locations • Race can be diverted at any point • Israeli Defense Force – “Ipcha Mistabra” • The opposite is most likely • Small group in the intelligence branch • Briefs Officials and Leaders on opposite explanations for scenarios
- 16.

- 17. What makes a red team effective?
- 18. Red Cell Effectiveness • Ex. 57th adversary tactics group • Only Highly skilled pilots are allowed to become “aggressors” • Allowed only to use known adversary tactics and techniques depending on who they are emulating • Same should apply to all red teams • Adversary emulation is key to realistic simulations
- 19. Red Cell Effectiveness • Effective adversary emulation can mean being a “worse” threat actor • Tests defenders “post- compromise” security posture. Aka “assumed breach model” • Post compromise / foothold can also save valuable time and money.
- 20. What are the benefits of an effective Red Cell? • Train and measure IR teams detection and response. • MSFT measures this as MTTD MTTR Mean time to detect, and Mean Time to Recovery • Validates investment in very expensive security products, services, and subscriptions
- 21. Putting it all together – Adversary simulation • Emulate realistic threat actors TTPs • Assume breach model • Model attacker activity to your environment / risk • Information exchange between red and blue teams* • Protect Red Team culture • Repeat in a reasonable amount of time

- It was a dark and stormy night. “Captain, captain, wake up!” “Ohh … What is it?” “Sorry to awaken you sir, but we have a serious problem.” “Well what is it?” “There’s a ship in our sea-lane about 20 miles away, and they refuse to move.” “Tell them to move.” “Sir, we have. They won’t move.” “I’ll tell them!” The signal goes out: “Move starboard 20 degrees. At once!” The signal returns: “Move starboard yourself 20 degrees. At once.” “I can’t believe this. I mean, I’m a captain. Let them know who I am. I am important.” The signal goes out: “This is Captain Horatio Hornblower the 26th commanding you to move starboard 20 degrees at once.” The signal returns: “This is seaman Carl Jones the third commanding you to move starboard 20 degrees at once.” “What arrogance! Who is this joker? I mean, we’re a battleship! We could just blow them — let them know who we are!” The signal goes out: “This is the Mighty Missouri, Flagship of the Seventh Fleet!” The signal returns: “This is the Lighthouse.” That’s a story thats found in the Naval Proceedings Manual where they literally interpreted a lighthouse to be a ship, but I like the story because it helps me introduce this subject: That there are specific ways of thinking that are very common, that make it very difficult to be effective at securiing an organization. And I want to share some of those thought patterns with you today so will be aware of them and can hopefully operate your organization more effectively with that knowledge. So, I’d like to share with you some things I’ve learned in my career in information security, these are my perspectives and opinions on techniques for improving the security of your organization…. The ideas are not new or revolutionary. I’m just trying to share what, in my experience I feel works well in regards to redteaming
- So at a high level, we talk about…
- Just briefly let me tell you my story …. I’ve worn various security hats in my career, some defensive and offensive, from helpdesk to redteaming I’ve done about everything in between and I like to think that that gives me some perspective on the challenges of security in an organization.
- Both Approach, Mindset, and TacticsIf you are a leader in an environment you probably don’t know everything that is going on. If you are wise enough to come to this conclusion you need a red team to be the bring an alternate perspective The alternative perspective would apply to your problems, and the problems of your adversary
- Earliest evidence of the origins of redteaming came out of military wargaming exercises, 1976 – Hardliners in the Ford administration didn’t agree with the CIA’s conclusion. Believed that the U.S. had a capability gap. Team “B” of experts with access to all information about known soviet military capabilities and came to an alternative conclusion compared to the CIA report.
- Example of a scotoma Red teams responsibility is to see other teams blind spots and predict failures To do this they need to be aware of their own blind spots a partial loss of vision or a blind spot in an otherwise normal visual field.
- Lets try a game… Find all the red you can in the room… Now… Where is the brown
- Military examples Translate this to real world / business scenarios
- Multiple contingency plans for mulpiple scenarios As a result of the redteam simulation they are able to better pretect the marathon - They are directed to come to the opposite conclusion of whatever the current plan or conventional wisdom is. They don’t just brief generals. They go to parliament. They brief the prime minister’s office and the prime minister’s Cabinet. They describe their jobs—one of the individuals I know who did the briefings—as exhaustive. You have to essentially be argumentative by design. You have to challenge and doubt everything that happens.
- The key takeaway here is to understand that it is the highly skilled indivudual who can become an aggressor You have to be good enough, to restrict yourself to a specific capability or skillset, but that capability and skillset changes based on who you are emulating

- This is a great argument for Red Teams ingesting threat intelligence reports < they can work it into their tradecraft for redteam operations If you want to spend a year on an op working to get in, with an 0-day you can, but the simple fact is, if an adversary wants in bad enough, they will get in. Again, if you know an adversaries MO, storyboard it, and determine where it could get caught and where defenses are lacking Debrief after op completion Teams need to be external in terms of culture, but internal and aware in terms of critical thought Demoralizing if the blue team gets crushed week in and out
