Checking your network security involves several steps:  Audit Your Security System: Review your present security system to see if there are any potential vulnerabilities that can be exploited.   Use of monitoring tools: Use tools like Fidelis Network Detection and Response (NDR), which give you real-time information on your network's traffic and alert you in case some suspicious activity across your network is detected.  Conduct Penetration Testing: Perform this regularly because your network defense can have some loopholes.  Audit Access Controls: Ensure that specific systems and sensitive data are only accessible to authorized employees.  Update Security Policies: Finally, update the security protocols. Since threats keep evolving, your protection from these threats should, therefore, be updated as well. This will also help you comply with industrial standards.
