Every employee should have access only to information relevant to her or his role for a period for how long the information is required. You should have a robust system to protect the confidential information of your business engaging a combination of the physical or electronic barriers and staff education. You should hold security checks, leaving interviews when the staff members leave the work by blocking their access to the information. The confidentiality policy should be notified to all the staff members. The material you share with employees should have a mark of copyright to convey the confidentiality to the staff members if you own the copyright of the material. To protect the information of your business or customers, you must conduct privacy impact assessment.
An enforceable non-compete agreement and a disclosure statement must be agreed upon with the employees who are exposed to the confidential information of the business. You must prepare a crisis management plan to deal with any kind of information stealing or asset theft from the business to maintain the culture of information secrecy.
