Application Security

Security work in a business application can start with a specific question: who changed this record, who can see payroll data, what happens to card numbers, or what an auditor will ask for next quarter. IKRC reviews existing systems and builds the controls those questions need. No system is ever completely secure, so the work is about lowering specific risks and making problems visible fast.

Access and audit trails

We look at how users are authenticated, how permissions are checked on each action, and whether sensitive changes leave a record of who did what and when. Where that record is missing, we add application-level audit tables or database auditing so HR, finance and support staff can answer "who changed this" without a developer. We also cover backups and restore tests for data loss and corruption.

Payment card data

For PCI DSS, a central design decision is whether card data ever touches your systems. Handing payment processing to a compliant third-party processor reduces the PCI DSS requirements that apply to you, but according to the PCI Security Standards Council the merchant is still responsible for confirming the provider is PCI DSS compliant for the services used, keeping written agreements, and monitoring the provider's status at least annually. IKRC can design payment flows that keep card data out of your application. We do not certify compliance, and your own validation obligations are confirmed with your acquirer or payment brand.

HIPAA and other regulatory programs get the same treatment: we build the technical controls your compliance owner specifies and document what the system does.
