Should I encrypt session data?
If your application is on a shared host, and your session data is being kept in some unsecure central location where it could be open for other users to read, then yes, technically there is some security benefit to encrypting your sessions.
Why is it a best practice to encrypt and password protect backups?
Backup application encrypts the data first and then uploads it to storage. It is strongly recommended to keep your password safely with you since it won’t be stored anywhere in the cloud or encryption software.
How do I encrypt session data?
Passphrase-based encryption (PBE), which creates a symmetric-key encrypted session key packet using a passphrase (like a “password”) to encrypt the data; only this password can be used to decrypt the data.
How do I encrypt a session?
A caller, to protect the confidentiality of data, can encrypt it with a command encryption key known only to the caller and the TPM. The encryption key is determined, in part, by the parameters used to start the session (more on that later). A decrypt session then informs the TPM that the first parameter is encrypted.
How is a session key used in encryption?
A session key is any encryption key used to symmetrically encrypt one communication session only. In other words, it’s a temporary key that is only used once, during one stretch of time, for encrypting and decrypting data; future conversations between the two parties would be encrypted with different session keys.
What can a key be used for in encryption?
In encryption, a key is a string of data that is used to alter messages so that they become encrypted – in other words, so that the data appears randomized or scrambled. A key is also used for decrypting the data, or translating it from its scrambled form to its original form. (See What is a cryptographic key? to learn more.)
Can a key be used in multiple sessions?
In a session that uses symmetric encryption, multiple keys can be used, but a message that is encrypted with one key is decrypted with that same key.
The set of encryption keys for these chunks of customer data is itself encrypted. The keys used to encrypt the blobs are stored in the SharePoint Online Content Database. The Content Database is protected by database access controls and encryption at rest.
