Conversations With Cyber Security Professionals

eLearnSecurity recently sat down with Chloé Messdaghi, discussing her journey from business consultant to cyber security professional.

Chloe is the VP of strategy at Point Three Security. She is a security research advocate who strongly believes that information security is a humanitarian issue. Besides her passion to keep people safe and empowered both on and offline, she is driven to fight for hacker rights. She's the founder of WomenHackerz and the president and cofounder of Women of Security and heads the San Francisco Bay area chapter.

Like so many others who are interested in a career in cyber security, Chloé showed an interest in technology at an early age then was curious about how cyber crime fit into her university studies on terrorism.

Unfortunately, like many women, Chloé was initially ignored. "I think the first time I realized that I want to be in the (hacker) community was probably when I was in the sixth grade," she said. "I was in a computer class and I remember going up to my instructor saying, I want to learn what hackers do. Can you show me? And he's like, Oh, that's so cute, but that's for boys."

Fighting Discrimination in the InfoSec Community

After Chloé joined her first cyber security firm, she quickly used her research background to immerse herself in the security world. Yet she still faced discrimination that would attempt to define her career:

"When I first started, I just didn't know that I was dealing with discrimination here and there. So, if I would go to a meeting, I would be treated differently. If I was in a boardroom, I'd be treated differently. For example, if you're in a room and you bring up a thought or an idea, everyone ignores it until the male says the exact same line and they applaud it."

Navigating Discrimination and Abuse

Chloé hears weekly from women in cyber security who have been discriminated against or sexually assaulted by their superiors. They are confused about how to navigate chain of command and human resources after such experiences.

People who are sexually assaulted "go to HR on their own to tell someone and within a couple of weeks they are let go from their job. And what happens is they go through their Slack, they go through their emails, they try to prove that that person wasn't capable of doing their job. And so, then what happens is that when you're getting fired, people sign that NDA."

Facing Discrimination Together

While women face discrimination in male-dominated industries like cyber security every day, Chloé wants everyone to know they have support, and there are groups who are willing to help. That's one reason she started WomenHackerz and Women of Security have chapters around the world and offer spaces where women can share their stories and learn from the experiences of others.

Recent Playtesting: Apotheosis (FKA Worker Learning)


Apotheosis

Since I last posted about it, I've had the opportunity to play Apotheosis (the current title for my Worker Learning game) about a dozen times. We've quickly iterated on a couple of different aspects, going from 8 starting workers (one level 1 and one level 2 of each type) to 4 (one of each type, some level 1, some level 2, depending on turn order), adding a space to recruit more workers (I'm torn on this), adding a space to pay a chunk of resources for steps on the victory tracks, and tweaking the resolution of the Recall turns and the requirements and rewards for adventures.

The current version looks something like this:

You start with a Fighter, a Cleric, a Mage, and a Thief, 0/1/2/2 of them are level 2 at the beginning if you are player 1/2/3/4 (the ones that start leveled up are dealt to you randomly, and no two players will have the same combination of upgraded starting workers).

You take turns either placing a worker and gaining the benefit of that space (your worker must be at least tied for the highest level in that area), or recalling your workers and sending them on an adventure. Most spaces are better if you are higher level, or the right class. You can gain resources, train (level up), claim adventures (so nobody can do them out from under you), buy progress on the victory tracks, turn resources into blessings, which are like wild resources, visit the Throne Room to earn royal favors, or visit the tavern to recruit more workers.

When you place a worker, you have the opportunity to play a Side Quest card for either of 2 effects (one cares about what type of worker you are placing that turn, the other doesn't). When you recall workers, you earn steps on the three victory tracks, and if you qualify, you may do an adventure to earn more steps. The adventures have 3 tiers, and the higher the tier you do, the better the rewards. After returning from an adventure, your workers level up, becoming better at their jobs.

When you do certain Side Quests, or tier 3 adventures, you get a special resource called Spoils. You can visit the throne room to turn those Spoils into Royal Favors, which you can use at certain points on the victory tracks to take a "shortcut" as well as earn a Boon (reusable power card).

Design concerns


I'm noticing a real tightness in the design -- a difficulty creating adventures that are both doable by a player who has not recruited any new workers, but also doable by a player who has. The current level cap is 6, and so I wanted the adventures to require max 6 levels of any one class. If you hire a worker, then place it, and recall once, then you have 2 workers who's levels total 4 or 5 -- that's almost maxed out already! I am considering making the level cap 8 instead of 6, but d6s are easier to use in the prototype. Doing so would allow for more variety and more texture in the adventure requirements. It's also possible that not every adventure needs to be doable without recruiting another worker.

With just 4 types of worker, many of the tier 2 adventures require 3 of the 4 types. So you basically need to train up all of your workers if you wan to use them at all, there's not really such a things as choosing a class and neglecting it. I'm considering adding a 5th worker type to help with this -- it would allow the adventure requirements to be much more diverse.

Another thought is to add Split and/or Prestige classes:
Split classes would be like regular workers, that count as either one or the other of two types (like a Fighter/Thief would count as either a Fighter or a Thief.
Prestige classes would be like super workers that count as BOTH of two different types (Paladin = Fighter AND Cleric). For these you would probably have to discard your previous worker, therefore they BECOME a dual class worker.

Brainstorming possible solutions


Split/Prestige class workers would be pretty cool. but that sounds like expansion content to me. However adding a 5th (maybe even a 6th?) class to make the adventures more different from each other sounds reasonable. But that idea comes with its own challenges...

In the current game, each worker type is associated with 1 resource, and 3 of them are associated with one of the victory tracks. When you recall a fighter, you advance on the Crown Imperial track, and adventures that require fighters advance you further on that track. Thieves are associated with the Prince of Thieves track, and Mages are associated with the Mastermind track. Clerics are great supporting characters -- they aren't associated with any particular track, but instead give you Blessings, which are sort of like a wild resource that can be used in various different ways.

So if another worker type is added, do we need another resource? That might be a pain, but would be doable. Another victory track? I don't necessarily think that's a good idea (though I suppose it could work). What is another iconic adventurer class anyway?

One possibility is to make this 5th class a sort of Split/Prestige class like I mentioned above. Like a Paladin, which could act as either (or both) of a fighter or a cleric. But that would simply overload the fighter related stuff. So maybe better if whatever the new class is, it doesn't advance any of the tracks, but is otherwise "better" than a normal worker (counts as all types when placing?). Or perhaps it advances the track of your choice, and has some other drawback (doesn't count as any type when placing?).

As for the level caps, one way to fix that situation is to not use dice as workers (even though it's super convenient for prototypes). Instead, perhaps a mini or standee, with a base that has a little pointer, then a dial could be attached to the bottom such that the pointer points to the number on the tile corresponding to the current level. This is a user friendly way to not have to use dice, and therefore not be as limited in their value. The level cap could easily be 8, or even 9!

Another, different possible solution to the over-leveling issue is to limit the level-ups to only 1 per recall turn. This would slow things down considerably, and it would probably matter quite a bit which one you choose to gain levels and which ones you don't. It might also make a much bigger difference between playing 1-2 workers then recalling vs playing 3 or 4 before recalling. I'd be afraid this is TOO slow, but it ought to be easy enough to test. If it works, then that would make a level cap of 6 potentially viable after all.

DE: Miserable Meat Mountain

Get. Cleaved. Hard.

Today is a special day.  Why?  Because I'm posting about a hypothetical competitive list that I've been working on that features Coven.  The idea of this list came from friends of mine in the competitive 40K circuit that has been actively discussing the validity of Coven.  Personally, I think that Prophets have some of the strongest units in all of the Dark Eldar book.  The 4++ across the entire army is absolutely insane considering all the buffs you can stack.

What you have here is a list that's capable of outputting a dramatic amount of firepower on top of having a huge amount of resilient, melee pressure that can move surprisingly quick across the battlefield.  All Haemonculus units move 7" (Wyches move 8") across the battlefield where Talos can move a surprising 8".  When you consider the fact that Talos can now Fly, you really to question all these massive, resilient meaty things are being thrown into your face in the most ridiculous way possible.

Here's the list, I'll go into detail below:

Miserable Meat Mountain
1993 // 9-11 CP

Black Heart Bat +5 CP

HQ:
Archon, Agonizer, Blaster = 91
Cunning, Living Muse

Archon, Agonizer, Blaster = 91

TROOP:
5x Warriors, Blaster = 47
10x Warriors, 2x Blaster, SC = 104
10x Warriors, 2x Blaster, SC = 104
10x Warriors, 2x Blaster, SC = 104

PARTY BOATS:
Raider, Dark Lance = 85
Raider, Dark Lance = 85
Raider, Dark Lance = 85
Raider, Dark Lance = 85

HEAVY:
Ravager, 3x Dissies = 125
Ravager, 3x Dissies = 125
Ravager, 3x Dissies = 125

+++

Prophets Spear +1 CP

HQ:
Urien = 90
Diabolical Soothsayer

ELITE:
10x Grotesques = 350

HEAVY:
Talos, 2x Macro, 2x Haywire = 99
Talos, 2x Macro, 2x Haywire = 99
Talos, 2x Macro, 2x Haywire = 99

>>>

So what you do here is take Alliance of Agony to enable the Diabolic Soothsayer on Urien.  This automatically pays for itself and you can possibly get 2 more CP depending on what you roll.  All in all, this makes your CP count 9-11 depending on hot your dice are on this roll.

Urien himself is pretty amazing.  For 90 points, which is 15 points or so more than a regular Haemonculus, you get +1S and Ld. on top of the +1T for all units within 6" of him.  He's fast enough to keep up with the rest of your army, is T6 because his aura also works on himself, and is incredibly difficult to kill because he halves damage coming into him.  However, what makes him work is the rest of the units he brings along with him as part of your army.  With his +1S/T aura, he makes all the Grotesques shielding him T6, 4++, 4W with FNP.  Each of those beasts has 5 S6 AP-2 1D WS3+ attacks and that's going to do some serious damage to whatever they touch.  The Talos is even more deadly because they are now T7, 4++, 7W with FNP with 6 S8 AP-2 2D WS3+ attacks each with an additional 2D3 Haywire Blaster shots.  Sure, these hit on 4s, but it's still nothing to sneeze at, especially if you're a vehicle.

I can see a deployment strategy for these guys as Grots in front, Urien in the middle, Talos all around Urien.  This gives him a Spear of Meat that he can drive directly into the heart of the enemy, making them shit their pants while your Kabal units do their thing.  What makes a list like this work is that you cannot really ignore the cascading mountain of meat running into your lines.  Sooner or later you'll have to deal with them and they're an absolute pain to deal with.  If 10 Grots get into combat, they're going to throw out 50 high-strength attacks that are going to murder pretty much anything they touch.  They're incredibly difficult to kill and they will beat out most things in combat easily due to sheer attrition and unit preservation.  Unlike most fatty units, Grots don't die easily and so the overall damage of the unit will stay intact much longer.

In short, your opponents are left reeling from the damage that your firebase of Living Muse Ravagers and Raiders are inflicting, but they're too distracted to deal with them because of all the Coven units closing in.  If they focus on the vehicles (and you should play the range-game here at first), they're also making a mistake.  Hopefully, you've played smart enough to reduce as much damage as possible and watch your Coven units smash into his lines untarnished.  This is Tough Decisions 101 and Dark Eldar plays this game much better than most.  When it comes to pure pressure, I think Prophets is the way to go if you want to bring a melee force that can threaten anything from MEQ to Imperial Knights

Yes, I'm going to call this list experimentation Miserable Meat Mountain after the competitive Warmahordes Trolls list.  It's a Black Heart Bat and Prophets Spear, so it's relatively easy to construct.  Now, help me out with this grand experiment and field this list if you're capable of fielding this!
