What is different about IT for finance and accounting

Financial firms carry client money and client identity, which makes them a standing target and puts them under examination. The provider is expected to produce evidence, not assurances: change logs, access reviews, and a written incident response plan an examiner can read.

Compliance that actually bites

Federally regulated financial institutions answer to OSFI, whose Guideline B-13 sets expectations for technology and cyber risk management and which carries incident reporting duties. Investment dealers are overseen by CIRO and the provincial securities commissions, PIPEDA and Quebec's Law 25 govern personal information, and PCI-DSS applies wherever cards are handled. US rules such as the SEC and FINRA expectations apply only to firms carrying US-registered business.

Questions worth asking a provider

  • What evidence can you hand an examiner without us preparing it first?
  • How do you handle privileged access, and who at your firm can reach our data?
  • What is your notification process and timeline if you detect a breach in our environment?
