Abstract

Logic may identify information of a first electronic mail document associated with a control, the control to comprise a process to mitigate a risk. Logic may select the electronic mail document based on the information. Logic may determine metadata for the electronic mail document, the metadata. Logic may generate a first value representative of the electronic mail document based on application of a mathematical algorithm. Logic may generate a log entry for the electronic mail document comprising the metadata and the first value. Logic may encrypt the log entry with an encryption key. And logic may store the log entry in an encrypted ledger with a log entry date and a unique log entry identifier.

First claim

What is claimed is:

1 . An apparatus comprising:
memory; and logic circuitry coupled with the memory to perform operations to: identify information of a first electronic mail document associated with a control, the control to comprise a process to mitigate a risk; select the first electronic mail document based on the information; determine metadata for the first electronic mail document, the metadata comprising an email identifier, an email address, and an email date; generate a first value representative of the electronic mail document based on application of a mathematical algorithm; generate a log entry for the electronic mail document comprising the metadata and the first value; encrypt the log entry with an encryption key; store the log entry in an encrypted ledger with a log entry date and a unique log entry identifier; detect an attempt to delete or modify the first electronic mail document; determine that the first electronic mail document is associated with the log entry in the encrypted ledger; and prevent deletion or modification of the first electronic mail document after a determination that the first electronic mail document is associated with the log entry in the encrypted ledger.

2 . The apparatus of claim 1 , the logic circuitry to further perform operations to:
monitor for additional electronic mail documents in an email thread associated with the first electronic mail document; and store, in the encrypted ledger, a log entry for each of the additional electronic mail documents in an email thread associated with the first electronic mail document.

3 . The apparatus of claim 2 , the logic circuitry to further perform operations to:
monitor for attempts to modify the first electronic mail document and the additional electronic mail documents in an email thread associated with the first electronic mail document; and block the attempts to modify the first electronic mail document and the additional electronic mail documents in an email thread associated with the first electronic mail document.

4 . The apparatus of claim 1 , the operation to select the electronic mail document to include operations to:
identify one or more tags associated with the control, and correlate the one or more tags with the information.

5 . The apparatus of claim 1 , the operation to select the electronic mail document to include operations to:
identify one or more tags associated with the control, and correlate the one or more tags with the information associated with an attachment of in the first electronic mail document.

6 . The apparatus of claim 1 , the operation to identify information to include operations to:
generate input data for an inference engine based on the first electronic mail document, provide the input data to the input of the inference engine, and determine that the first electronic mail document is associated with the control based on an output of the inference engine.

7 . The apparatus of claim 6 , wherein the inference engine comprises a machine learning engine trained with training data including electronic mail documents associated with one or more controls in a set of controls, the one or more controls to include the control.

8 . The apparatus of claim 1 , wherein the metadata comprises a from email address, a to email address, a cc email address, a subject line, and one or more control identifiers.

9 . The apparatus of claim 1 , wherein the metadata comprises information from attachments of the first electronic mail document.

10 . The apparatus of claim 1 , wherein the first value comprises a checksum of the electronic mail document, a hash of the electronic mail document, or a combination thereof.

11 . A non-transitory storage medium containing instructions, which when executed by a processor, cause the processor to perform operations, the operations to:
parse metadata of one or more electronic mail documents; infer information of a first electronic mail document associated with a set of controls; access the set of controls to obtain data associated with the set of controls; correlate the information with the set of controls based on the data associated with the set of controls; select the first electronic mail document based on correlation of the information; generate a log entry for the electronic mail document comprising metadata and a first value, the first value comprising an encoded representation of the electronic mail document; and store the log entry in an encrypted ledger with a log entry date and a unique log entry identifier; detect an attempt to delete or modify the first electronic mail document; determine that the first electronic mail document is associated with the log entry in the encrypted ledger; prevent deletion or modification of the first electronic mail document after a determination that the first electronic mail document is associated with the log entry in the encrypted ledger.

12 . The non-transitory storage medium of claim 11 , wherein the operations further comprise operations to:
monitor for additional electronic mail documents in an email thread associated with the first electronic mail document; and store, in the encrypted ledger, a log entry for each of the additional electronic mail documents in an email thread associated with the first electronic mail document.

13 . The non-transitory storage medium of claim 12 , wherein the operations further comprise operations to:
monitor for attempts to modify the first electronic mail document and the additional electronic mail documents in an email thread associated with the first electronic mail document; and block the attempts to modify the first electronic mail document and the additional electronic mail documents in an email thread associated with the first electronic mail document.

14 . The non-transitory storage medium of claim 11 , wherein the operation to parse metadata includes operations to:
generate input data based on the metadata of the first electronic mail document and attachments, and provide the input data to a natural language processor, the natural language processor to determine tags associated with the first electronic mail document.

15 . The non-transitory storage medium of claim 14 , wherein the operation to infer information includes operations to correlate the one or more tags with the one or more controls via a machine learning engine to classify the electronic mail document as related to the set of controls or to determine a probability that the electronic mail document is related to the one or more controls.

16 . The non-transitory storage medium of claim 11 , wherein the operation to infer information includes operations to:
generate input data for an inference engine based on the first electronic mail document, provide the input data to the input of the inference engine, and determine that the first electronic mail document is associated with the control based on an output of the inference engine.

17 . The non-transitory storage medium of claim 16 , wherein the inference engine comprises a machine learning engine trained with training data including electronic mail documents associated with one or more controls in a set of controls, the one or more controls to include the control.

18 . The non-transitory storage medium of claim 11 , wherein the metadata comprises a from email address, a to email address, a cc email address, a subject line, and one or more control identifiers.

19 . The non-transitory storage medium
