To safeguard your ServiceNow instance, you need a multi-faceted security strategy that encompasses various layers of defense.

"Security is a Journey, Not a Destination Crawl, Walk, Run."

Here are some steps you can take to secure your ServiceNow instance:

1. Enable multi-factor authentication (MFA)
   MFA adds an extra layer of security to your ServiceNow instance by requiring users to enter a code from their phone in addition to their password. Implement multi-factor authentication (MFA) to add an extra layer of protection, making it much harder for unauthorized individuals to gain access.
   To enable MFA please refer to this: How to activate Multi Factor Authentication (MFA) on ServiceNow
   
   
2. Use strong passwords and password encryption
   Strong passwords are essential for protecting your ServiceNow instance. Make sure that your passwords are at least 12 characters long and include a mix of upper and lowercase letters, numbers, and symbols.
   You should also enable password encryption to protect your passwords from being compromised.

6. Incident Response Plan
   No security measure is foolproof, so having a well-defined incident response plan is essential.

This preparation will help your team respond swiftly and effectively when a real security breach occurs.
   You can also use ServiceNow's security incident management capabilities to respond to security incidents.
   
   
7. Data Encryption
   Data encryption is your ally in protecting information in transit and at rest. ServiceNow supports industry-standard encryption protocols to secure data both when it's moving between your instance and users and when it's stored in the database. Ensure that you've enabled encryption for all sensitive data elements, including passwords, financial records, and personally identifiable information (PII).
