• Security-devops-maybe-DBAs-too-oh and-QA-sure-who-else?

The Watering hole attacks of Feb
Monday, 11 November 13
@benjammingh
Other than the occasional RCE/SQLi or 0-day, companies just aren’t getting breached directly through their servers like they used to.

@benjammingh
Surprise!• You can’t defend against unknown
attacks.• Clue is in the name.

@benjammingh
Rejoice. That mostly doesn’t matter!

@benjammingh
Treat the symptoms• Lateral movement can be more
important than how they got in.• You don’t care that they broke a
window, you care that they got in your living room and took your TV.
• (still fix your window)

@benjammingh
Hudson hawk reference• Why is /bin/sh running on your
webserver?• Why is your webserver trying to SSH to
other hosts?• Why is the Cold Fusion process reading
arbitrary files off of disk (SE/NSA Linux time)

@benjammingh
But still patch• Please, still patch things.• Know that it isn’t a panacea.• Realise that is okay.
Monday, 11 November 13
@benjammingh
Please do patch!
• No really!

Logs are your eyes.
“If it’s not monitored... ...it’s not in production”
Well“If it’s not logged, did it really happen?”

@benjammingh
You have a limited number of eyes.

Pen Testing• Don’t pay someone else to tell you to
patch things.• Don’t pay someone to run Nessus.• Hire more security people before paying
for pen-tests.• Attack simulations are better. http://
bit.ly/attacksims
Monday, 11 November 13
@benjammingh
Attack simulations?• Everything in scope.
Monday, 11 November 13
@benjammingh
Attack simulations?• Everything in scope.• Don’t have security run it.

@benjammingh
Attack simulations?• Everything in scope.• Don’t have security run it.• Don’t block on fragility.

@benjammingh
Transparency!• Invite people to the brief.• Don’t just expect a PDF.• Treat it as a postmortem.• Come out of it with a set of actions.
Monday, 11 November 13
@benjammingh
Game days.• Ops’ “game day” simulations, but for
security.

Phishing• Who’s stopped phishing?• You’re not going to stop phishing.• That doesn’t matter.• Don’t think you can fully eliminate it, get

• Silo smashing in to one new larger silo!
Monday, 11 November 13
@benjammingh
DevSecOpsFarmerQueen• Many hats.• Not just dev.• Not just ops.
• Security doesn’t justmagically happen.
Monday, 11 November 13
@benjammingh
Get security involved!• This can be done is all sized
environments!• Small - having someone who has a security background or
interest.

Security are people too!
Monday, 11 November 13
@benjammingh
Security are people too!• they just might not always act like it...• security is the only area of technology
with genuine adversaries.
Monday, 11 November 13
@benjammingh
Infosec, this one’s for you• Dev and ops (and everyone else) are
people too.• They made those decisions without
malice in mind.• People don’t go out of their way to
make things insecure!
Monday, 11 November 13
@benjammingh
Primary action items• Don’t just say “did you speak to security
about this?”• Get people involved!• Security has never [succesfully] been a
check box.
Monday, 11 November 13
@benjammingh
Reducing barriers.Having an approachable security team is the most important thing they can do.
The second you lose the ability to talk to them about anything, you effectively lose your security team.
