Here are some of the steps that could be taken to solve this problem:
1. Maintain a log of all network access.
- The more company network traffic is watched, the more suspicious activity is likely to be found. Reconnaissance operations are usually carried out before data breach attempts since thieves need to know which defenses must be circumvented during an attack.
- Data leak prevention systems can help organizations find and fix security flaws, decreasing the danger of reconnaissance campaigns.
- Security policies may need to be changed to enforce privileged access to exceptionally sensitive data.
2. Make sure all endpoints are safe.
- An endpoint is a remote access point that communicates with a business network, either through end users or autonomously. Computers, mobile devices, and Internet of Things (IoT) devices are all included.
- As most businesses implement some form of remote working, endpoints have become more dispersed (often even worldwide), making them more challenging to secure.
- Endpoint security is aided by firewalls and VPNs, but they are insufficient. Employees are frequently misled into bringing malware into an ecosystem to get around these security obstacles.
- Employees must be trained to recognize fraudsters' ruses, such as email phishing and social engineering attempts. Education is a powerful tool for preventing data leakage.
3. Examine each of your permissions.
- Users that don't need access to your personal information may now have it. All permissions should be evaluated as a first step to ensure that only authorized parties have access.
- Following this, all critical data should be divided into multiple levels of sensitivity in order to govern access to various data pools. Only the most trusted personnel should have access to highly sensitive information.
- This privileged access assignment process may also expose any malicious insiders that are aiding in the data exfiltration.
