Similar comments in previous articles but oh so true

For a web application under development, it's important for developers to seek guidance during the design of the authentication procedures. The goal is to enforce the security of the design of the authentication procedure by considering human factors and design errors. For example, to discover business logic flaws associated with authentication and authorization, we would need to correlate usability issues (lost phone, security unawareness) with human behaviors (active session, autocomplete forms).

On this basis, we can provide a set of security and usability requirements developers and architects can use during the early design of the end-user authentication procedure to prevent business logic flaws.


I remember reading an article from DR that talked about combining "IT Security" with "DevOps" to create a "SecDev" or "DevSec" group. I think in this particular case, this is a good use case where the security teams can get involved in the security design aspects and make suggestions as to how to utilize existing tools from operations:
  • SAML
  • Password Hashing
  • SSO using same username and password (passthrough)
  • Read-only AD/LDAP replicas
  • Single or Multi-tenant forest creation
  • Key or Token exchange
  • MFA/2FA

We are seeing more of this, Louisiana is under a state of emergency (schools are being plummeted by various cyber actors), by working with various groups from different regions of the US, we can start coming up with better ways of addressing this cyber issue. A number of companies are doing a good job to help, it just depends on your budget, but if you have good people on staff, it may not have to cost the organization anything but labor cost.

Just a thought.
