Help the hackers get your data

Help the hackers get your data

In May 2018 something happened to the internet, GDPR came online,
and suddenly users in the EU had a lot more rights to their digital privacy,
which is awesome. But on the flip side the implementation of the GDPR and
procedures regarding it, are very vague and were meant to be written as
we go along, with whatever comes up as best practices.
Books and talks have been written and given about the data encryption, problems
encountered with event sourcing systems, questionaries about the purposes of
collecting user data... So many words and hours of many lives spent...
Yet, something has been overlooked, something so basic, we do not even notice it.
If you are working on an enterprise-class project or on other large projects,
you might have an infra team that would deal with this and tell you what you need
to do to be secure (at least good ones will)
But... if you are working on smaller projects, and you have mom and pop shops
to support, you deserve the same level of security bigger projects have...
I am talking about secrets and credentials management for your application, the most
overlooked aspect of any application.
This talk gives you a look at secrets management and security from the business side of things and tries to give you actionable information on how to talk to your clients, and bosses about this subject

    EXAMPLE 1: PRODUCTION-SCALE WEB APPLICATION Cost Dimensions - 2 SSH

    keys per server and 5 database credentials per database. - 2 API calls per SSH key per day. 24 API calls per database credential per day. - 7 API calls per database credential per week to rotate credentials safely. 15 secrets (2 SSH keys * 1 load balancer + 2 SSH keys * 2 web servers + 2 SSH keys * 2 app servers + 5 database credentials * 1 database) @ $0.40 / secret / month 4,040 API calls (2 SSH keys/server * 5 servers * 1 API call/day * 30 days + 5 database credentials * 1 database * 24 API calls/day * 30 days + 5 database credentials * 1 database * 7 API calls/week * 4 weeks) @ $0.05/10,000 calls $6.02 TOTAL (PER MONTH) @vranac - Software Crafting Serbia
  12. 53.

    EXAMPLE 2: USING EPHEMERAL SECRETS TO AUTHENTICATE MICRO SERVICES Cost

    Dimensions 5M secrets (each valid for 1 hour). 2 API calls per secret per month. Note: Since these secrets are stored in Secrets Manager for an hour, the price per secret is calculated as $0.40 * 1 hour / (30 days * 24 hours) = $0.00056 / secret/ hour $2,800.00 5M secrets @ $0.00056 / secret/ hour $50.00 10M API calls (5M secret * 2 API calls) @ $0.05/10,000 calls $2,850.00 TOTAL (PER MONTH) @vranac - Software Crafting Serbia

    HOW DOES IT ALL FIT TOGETHER: > vault token goes

    into config (ironic, I know) > token gets sent to the vault server, and client token is returned > only retrieval of secrets granted by the ACL assigned is possible > when lease on client token expires, vault token is used to obtain new one @vranac - Software Crafting Serbia
  14. 60.

    IN CASE OF BREACH: > your tripwire system is triggered

    > your files are downloaded (possibly config as well) > you remove server from public > you rotate the token generated > you update the config > you make server publicly available @vranac - Software Crafting Serbia

    BUT DO YOU USE SECRET MANAGEMENT ON EVERY PROJECT? >

    user data, maybe PII, maybe not? yes > any kind of sensitive data? yes > any kind of payments on the system? definitely yes @vranac - Software Crafting Serbia

    average cost of a large data breach (in which more

    than one million records are lost) in 2018 was $3.9 MILLION DOLLARS @vranac - Software Crafting Serbia
