Security assessment.
WHAT TO TEST FOR SPECIFICALLY
Authorisation on every money-related endpoint Amount and currency manipulation Replay of transactions Race conditions on balances Notification forgery Privilege escalation in internal tools
WHY RACE CONDITIONS SPECIFICALLY
They are frequently missed and directly produce financial loss.
HOW TO TEST THEM
Concurrent identical requests, repeatedly.
WHAT AUTOMATED SCANNING FINDS
Known vulnerability patterns, and configuration problems.
WHAT IT DOES NOT FIND
Business logic flaws, which are where financial systems fail.
WHAT THAT MEANS
Manual assessment is necessary, by someone who understands the money flows.
WHAT TO PROVIDE AN ASSESSOR
The flows, the roles, and what should be impossible.
WHY
Without that, they test the interface rather than the logic.
WHAT TO TEST IN A SEPARATE ENVIRONMENT
Everything, with realistic but non-production data.
WHAT TO ARRANGE PERIODICALLY
Independent assessment, particularly after significant change.
WHAT REGULATION MAY REQUIRE
Testing at defined intervals, with evidence.
WHAT TO DO WITH FINDINGS
Prioritise by financial impact, and fix within defined periods.
WHAT TO RETEST
Every fix.
