If I use Network Watcher to save logs in the Azure log analytics workspace, will those logs be encrypted? Also, what encryption method (AES256?) Should be used when it is encrypted?

    The data stored in log analytics is encrypted at rest by default. You have an option to encrypt the data at rest using customer managed keys.
    Here is a detailed document for your reference: customer-managed-keys

    There are 3 types of keys involved in Storage data encryption:

    1. KEK - Key Encryption Key (your Customer-managed key)
    2. AEK - Account Encryption Key
    3. DEK - Data Encryption Key
