Here are some tips on how to secure your SharePoint intranet from cyberattacks:
Keep your SharePoint software up to date. Microsoft regularly releases security updates for SharePoint. It is important to install these updates as soon as they are available.
Use strong passwords and enable multi-factor authentication (MFA). All users of your SharePoint intranet should use strong passwords and enable MFA. MFA adds an extra layer of security by requiring users to enter a code from their phone in addition to their password when logging in.
Use role-based access control (RBAC) to restrict access to your SharePoint intranet. RBAC allows you to grant users access to only the sites, libraries, and documents that they need. This can help to reduce the risk of unauthorized access to your content.
Use SharePoint auditing to track user activity. SharePoint auditing allows you to track who accessed what content and when. This can help you to identify suspicious activity and to investigate security incidents.
Use a web application firewall (WAF) to protect your SharePoint intranet from common web attacks. A WAF can help to protect your intranet from attacks such as SQL injection, cross-site scripting, and denial-of-service attacks.
Here are some additional tips:
Educate your users about security best practices. Your users should be aware of the risks of cyberattacks and how to protect themselves. Train your users on security best practices such as using strong passwords, being careful about what links they click on, and avoiding opening attachments from unknown senders.
Have a plan for responding to security incidents. It is important to have a plan in place for responding to security incidents. This plan should include steps for identifying and containing the incident, investigating the incident, and recovering from the incident.
By following these tips, you can secure your SharePoint intranet from cyberattacks and protect your content from unauthorized access.
Here are some examples of how you can secure your SharePoint intranet:
Require all users to use strong passwords and enable MFA.
