4. BYOD
 Bringing Your Own Dependencies The trend of systems development where development is primarily responsible for application dependencies in production.
5. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Evolution? The general trend away from top-down control and toward distributed and point to point solutions is also true for software deployment
6. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath OS-Based Dependencies • "operating system" provided by "operations" • packaging and release engineering provider by OS vendors • "yum install your-package" • Requires operations to update
7. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Lots of problems here • Limited selection • Generally "out of date" • Security fixes only • Do not normally include stability fixes.
8. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Custom OS Packaging • Reimplementations or updated versions of OS packages. • Again updates and additions added by operations
9. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath BYOD Partial
10. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Javascript • The original BYOD since ops can't package it (normally) • Partial since clearly does not bundle in the browser
11. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Java .war/.jar files • Packages up all java dependencies but doesn't package up the Java runtime. • (not really a java expert any more, so I defer to you)
12. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Chef (Product) • Provides full install of Ruby (including the executable) • Near impossible to get a client's ruby install to be "correct" • Chef (the company) is responsible for security for its components
13. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath BYOD Full
14. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Full VM • Mostly done by product vendors, and not (normally?) done by internal enterprise deployments • And of course cloud providers, provide a blank slate (but thats a different story).
15. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Docker • Dockerfile creates a container that provides all system requirements • Anything goes
16. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Go lang • Golang produces a single static binary that provides all code requirements • Dependencies are manually managed by developers • Third party code frequently un-versioned • By default directly pulls from HEAD on github for other modules • No shared libraries
17. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath This is a good trend for operations and development
18. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath • Ops should not care about what version of some python module is installed. They can focus on operations and operating systems • Turns operations into platform and in-house consultancy (ideally) • Devs starts taking responsibility for how their code is packaged and run. • Clear separation of duties (or perhaps responsibilities) Love it
19. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath But what about security?
20. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath The Old OS Model • Kinda nice! • "are we secure in our components?" is mostly a
 "apt-get/yum upgrade" invocation. • Actual work is outsourced (and centralized) to the OS Vendor, or the ops team
21. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath BYOD Model • Uhhh, now what • Docker containers and golang binaries are opaque • By inspection not clear what components are used, nor what versions. • Are they outdated? Insecure? Obsoleted?
22. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Evolution of Security • Security will need to get involved with
 release engineering • What does this mean?
23. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Absolutely • Security has to get involved with how software is made and deployed. • Demand fast, reliable deployment pipeline mechanism • (how fast and how often you deploy is your policy) • If anything, you need to be able to patch quickly
24. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Maybe? • Automation? Checking latest version of components. • What does "latest version" even mean? • Building manifests and bill of materials? And Displaying Them? • Alerting on manifest changes • ??? this is a work in process ???
25. RSA USA 2015 - DevOps Connect @ngalbreath Nick Galbreath Tooling Can Help • Sonatype • Black Duck • I have no first hand experience with any of them • I assume not all use cases here are covered as it really depends how software is built, packaged and deployed.
