This involves identifying all assets that need to be protected, such as servers, databases, applications, and data storage systems. By identifying these assets, you can begin to understand the scope of your network and what needs to be secured.</span>

This involves documenting all sensitive data, including the location and format of each data element, and assigning risk levels to them. This information can be used to determine access policies and ensure appropriate security controls are in place.</span>

Access policies should be developed to determine who has access to what data and under what circumstances. Access should be granted based on the principle of least privilege, meaning that users should only be given access to the data they need to do their jobs.</span>

It requires all users to provide multiple forms of identification to access the network or specific applications. This can include something they know, such as a password or PIN, something they have, such as a smartphone or token, or something they are, such as biometric data. By requiring multiple forms of identification, you can ensure that only authorized users are accessing network resources.</span>

This can help contain any damage caused by a breach. By segmenting the network, you can limit the impact of an attack and prevent an attacker from moving laterally through the network.</span>
