What kind of challenges have you faced as a Data Architect with regards to security and ensuring the integrity of a company's data is not compromised?

"At times, it can be difficult to come to a consensus on what should be deemed a security risk. There was an instance where some team members wanted to make changes to the process we used to upload franchisee data to our system. I believed these changes would create security risks, and to support my theory, I quantified the cost to the company if security was compromised. This information helped the team members view the situation from a different perspective and they revised their plan to reinforce data security measures."
