Below are five ways to overcome these security vulnerabilities.
First, strengthen password security. Require strong passwords and force users to change passwords frequently, such as every 90 days. Prohibit password reuse and prevent devices from saving passwords. Also, use multi-factor authentication.
Second, stop data loss. Create role-based segments that determine who can access how much of what data, and what they can do: view, edit, or share it. Tools to monitor user activity can help you detect insider threats, unauthorized behavior, and security breaches. Using information audit trails can also help prevent data leaks.
Third, encrypt data while it is in transit or at rest. Secure stored files using two-level encryption and a unique key for each file. Use SSL/TSL connections to secure data while in transit.
Fourth, ensure employees who access the network remotely do so securely. An employee’s home network is much less secure than the office’s. Require employees to use the company VPN or a separate network to connect to the company network.
Fifth, ensure all mobile devices used to access the company network are secure. Allow employees to choose their mobile devices from an approved list, so the device belongs to the employee but has company software and security installed. Sandbox a portion of the phone’s internal storage for sensitive data or partition off a virtual device within the device. The latter allows the user to use the same device in different ways, either as a secured device for work or a device for personal use.
