Collin utilizes multiple secure portals for its interactions with customers and stakeholders. EOs have role-specific permissions for write functionality in the integrated system. Password protection for all users of CNet and its secure portals is required. Passwords are changed every 60 days, with no repeats over a three-year period. Firewalls and filters protect Collin’s data and information from outside threats. Collectively, these measures enable data, information, and knowledge security, as well as confidentiality.
