Rotating service credentials for IBM Cloud Functions

Keep your service keys secret
If you have followed some of my work, you know that I use IBM Cloud Functions, i.e., a serverless approach, for many projects. The tutorials with a database-driven (Db2-backed) Slackbot and the GitHub traffic analytics are such examples. In this blog post, I want to detail some of the security-related aspects. This includes how to share service credentials (think of a database username and password) with a cloud function and how to rotate the credentials.

New! Db2 11.5 is available

Db2 11.5 is available
A quick post to inform you that Db2 11.5 has been released. Check out the What's New for Db2 Version 11.5 GA section in the Db2 Knowledge Center. You can download the GA version from the regular Download Db2 Fix Packs by Version site.


With a new release I typically go over the What's changed documentation to look for changes to registry variables, system views and deprecated functionality.


So much for the quick update. If you have feedback, suggestions, or questions about this post, please reach out to me on Twitter (@data_henrik) or LinkedIn.

After IDUG is before IDUG: Back from Db2 conference in Charlotte, NC

Last week the IDUG NA 2019 was held in Charlotte, NC. It featured 8 parallel tracks dedicated to Db2 for z/OS and Db2 for LUW and emerging technologies. In addition, two tracks for hands-on labs and workshops were offered. Personally, I delivered three presentations, moderated and attended sessions, and was active on Twitter. So what was on? Continue after the snap of Twitter photos from last week.

Cloud-based FIPS 140-2 Level 4 crypto service

Locks, keys, and data security
Yesterday, I got my hands on a FIPS 140-2 Level 4 cloud-based crypto service. If you are asking "what's that and what can I do with it?" you should continue to read. It is a dedicated HSM (Hardware Security Module) to manage encryption keys and offered as IBM Hyper Protect Crypto Services on IBM Cloud (HPCS). Here is what I learned while using the service.
