There is no general legal duty to eliminate every vulnerability, but the Personal Information Protection Act, SBC 2003, c 63, s. 34 requires organizations to make reasonable security arrangements to protect personal information. Other duties may arise from contracts and the law of negligence.
Regular security reviews, patching and access controls help show that your security arrangements were reasonable.
A known but unpatched vulnerability that leads to a data breach can undermine your defence that security arrangements were reasonable.
Fulcrum's privacy and data protection lawyers can help with these issues.
