In order to protect your official data, following are the steps that must be kept in mind.
1. Enforce strong passwords- Begin by using strong passwords for all important and confidential files.
2. Monitor data and its transfer- Checking and tracing the transfer of information through the organization will help in preventing the data from being misrepresented.
3. Limit access- Not all the systems must be open to all the members. It is important to make sure that the most sensitive data is managed only by the trustworthy and senior officials.
4. Two-factor authentication- By adding this layer of security, the system will get higher protection than using only password certification.
