# TTT Meeting 27/1/26

Attending: Matt, Luna, Maarten, Linda, Mischa, Donald
Apologies: 


## Last Meeting

## Representing "Hacked" Users
ML Should we considers this in any particular class? It is relevant.


(Note on the to do list is the threat descriptions, but want a consensus for that)

MS - phishing is much more of an issue in the IAM age, which is a related problem.
Luna - same issue with office365 etc.

Luna - it's a stolen token? But also stolen identity if abuse is persistant.

Need to have definition if hacked.

DIfference between abusive user and a hacked user?

Difference between say, a hacked lxplus account and a hacked federated iam account.

ML previous incidents (cryptomining) were all user abuse.

ML - if a lot of security investigations need to be done

Luna - widening net too much, too many lines.

ML - we are going to look at this, particularly within the 4/5 split that we did.

4 is a one shot, so 5 is the best home

As Luna mentioned, to first order not much difference between a valid user abusing resources and a stolen account.

ML - for Threat-4 We have an example of tokens being leaked inadvertantly (FTS logs).  
For threat 5 the abuse can be happen, but we should review category 5 with this respect/

Will need to update the Threat description for 5, to include this.

Tr-4 is not optimally named/have the right asset.

ML - maybe the asset should not be the primary key. 5 could now include digital identity.

Will need to rescore, but should try to merge first.


## Review of the Assessment
TR-1, Likelihood (2.5) too high, Impact might be too (3.5).  
-moved to 3 and 2  
Note improvements in IAM stability, and coming improvements.  

ML - Worry should be from Ops perspective. not security perspective.

Luna - move Fractions to full numbers during this exercise.

MD - Should we have considered TR-2 when talking about hacked users?  
Luna/ML - no, models things like minting your own tokens.

MD - notes that we have not many 1s for Likelhood, this is fair considering our "statistics."

TR -3 , both too high L(2.5), I(4).
Impact down to 2? Even less likely to happen now. Move to 2.

TR-6 round up Impact from 2.5 to 3. (at least)

TR-7 - keep as is (our current highest)


TR-4/TR-5 
Discussing merging strategies, between workflows and the two threats.

Can't merge Power and Regular user rows.

TR-5 would be the "primary" if we merged with TR-4

Should also consider merging workflows.

Luna suggests:  
Privilege user  
Regular User  
Privileged Workflow  

And split Compute and Data if needed.

ML - Data and compute should be kept split.

Privileged workflow might not the right name. refers to FTS and pilot frameworks.

Two FTS cases, the "better" case could be described as a mitigation.

Might want to sperated other threats, like leaked in logs.  
Discussed under TR-4. Should be included somewhere explcitly at the very least.

Luna - focus on mitigation and controls.

Some volunteers to go away and try to merge these as they best see fit, then compare this next time.


## AOB, Next Meeting

3pm CET Tuesday 10th as the next meeting? Clash with TIIME but okay.

Action on some of us to have a go at refactoring their own version of the spreadsheet.

There are minutes attached to this event. Show them.
    • 15:00 15:05
      Actions, Since Last Meeting 5m
    • 15:05 15:30
      Discussion: Risk Analysis 25m

      Inspiration may be taken from these assessments from EGEE and WLCG done many years ago:

      Work through the Workflows added by Maarten to the document, and review the scoring methodology.

      Continue discussion from the list.

    • 15:30 15:55
      Discussion 25m

      Probably just continuing the above.

      AOB, next meeting 5m

      Next regular meeting date would be the 27th of January at 15.00 CET.
