As IT organizations build and release software continuously, how do security teams become enablers of this pace? How can you ensure that the higher rate of change is not leading to lesser security? Join our webinar to learn how Pivotal and Signal Sciences work together to make app deployments faster *and* safer in cloud-native environments. This webinar will cover: - Best practices for implementing new security programs and incentivizing their adoption - How to simplify application layer security deployments across a variety of apps, teams and cloud infrastructures - How threat visibility and real time attack telemetry brings security context into DevOps teams, and improves response times. Presenters: Zane Lackey, Signal Sciences and Kamala Dasika, Pivotal

Stemcell Hardening
• Stemcell = Bare minimal OS +
PCF specific utilities and
configuration files
• Hardening guidance from
commercial and govt. sources
• BOSH Add Ons
– Ensure certain software runs
on all VMs managed by the
Director.
– E.g. security agents like
Tripwire, IPsec, etc., anti-
viruses like McAfee, health
monitoring agents l and
logging agents

Guest Speaker: Zane Lackey
• Started out in offense
– iSEC Partners / NCC Group
• Moved to defense
– First head of security at Etsy, built and
lead the four security groups
• Now scaling defense for many orgs
– Co-founder / CSO at Signal Sciences,
delivering a product that defends web
applications in the DevOps/Cloud world

21. Lessons learned being at the forefront of the shift
to DevOps/Cloud

22. Spoiler: Security shifts from being a gatekeeper
to enabling teams to be secure by default

23. What has changed?

24. The new realities in a DevSecOps world:
1. Changes happen multiple orders of magnitude faster
than previously
2. Security only becomes successful if it can bake in to
the Development/DevOps process
3. For many apps, cost of attack is so low you will be
attacked even if you’re not a brand name

27. Let’s change our approach

28. What new concepts should security focus on?

29. What new concepts should security focus on?
Visibility + Feedback

30. Except… These aren’t new concepts!

31. Performance monitoring, data analytics,
A/B testing are all about visibility + feedback

32. The same hard lessons are slowly shifting to
security

33. First, a story from the old days…

36. How can we improve?

37. Ex: Which of these is a quicker way to spot an
attack?

40. Surface security visibility for everyone, not just
the security team
(if the security team even exists)

42. Obtaining be3er feedback

43. Three keys to modern feedback loops:
1. Combination of bug bounty + pentests
2. Bounty is not a replacement for pentest, it augments
pentest
3. Bounty gives general but more real time feedback,
pentest shifts to giving more directed but less
frequent feedback

46. Visibility + Feedback success story:
“I discovered the vulnerability late Friday afternoon and
wasn't quite ready to email it to them … [Etsy] had
detected my requests and pushed a patch Saturday
morning before I could email them. This was by far the
fastest response time by any company I've reported to.”

47. Embrace DevOps, Cloud, and other means of
increasing velocity. But do safely by obtaining:
Visibility + Feedback

48. Thanks!
