11. #1 - Does this touch the internet?
● Dependency Fetching
● User Input
● External API Calls
● Third-party Integrations
● Messaging, MQQT, Websockets
● Uploads & Downloads
● etc...
If a feature touches the internet, we
need to ensure end-to-end security
from the supplier to the consumer.

12. #2 - Does this take untrusted input?
● UI Forms
● Calls to a Shared Database
● Cookies and HTTP Headers
● External API Responses
● And more…
If a feature takes untrusted input,
we need to validate it’s integrity
before use.

13. #3 - Does this handle sensitive data?
● Personally Identifiable Information
● Authentication / Authorization
● Private Communications
● Intellectual Property
● Location, Medical or Financial Data
● And more…
If a feature handles sensitive data,
we must pay special care to
encryption, handling, and storage.

1. Review application code using the Mantra
2. Identify any un-mitigated risks
3. Create a GitHub Issue to discuss the risk

17. Secure IaC is Difficult!
This section is not hands on, because
Secure IaC is more nuanced.
1. IaC tools have dependencies too
2. Infrastructure has the largest surface area
3. Defaults are the devil in the details

Weakness & Vulnerability Triage
1. What is the vulnerability rating?
a. Place a higher priority on higher ratings
2. Does this cause breaking changes?
a. Reduce priority for more complex implementations
(depending on how critical the rating is)
3. Do we have the skills/resources immediately
available to implement this upgrade?
a. If not, mark as blocked until you do
