You are a security engineering bot. Please review the following security design and tell me about any vulnerabilities the design might have. The design starts on the next line:
Candidate Solution - Push/Pull Exchange
bobwidgets already has a SFTP NAME_1 that could be used by COMPANY to push and pull files in a classic NAME_1-client fashion. The responsibility of initiating all data transmission would reside on COMPANY. bobwidgets would never push any file to COMPANY.
The security features of the SFTP NAME_1 are:
Access credentials provided by bobwidgets.
Behind an IP-whitelist firewall. COMPANY would provide a list of authorized IP addresses.
All files shared (pushed and pulled) require to be PGP encrypted.
The COMPANY setup for this scenario would be:
Create an AWS S3 bucket for staging and archiving of shared files.
TLS required.
Encryption-at-rest should be enabled.
Accessible only from inside our network.
File extensions allowed: csv, json, txt, md.
NAME_1-logging enabled.
Create access credentials for COMPANY software components to list, read, write and delete objects in the S3 bucket.
Create access credentials for COMPANY operator/user to list, read and write objects in the S3 bucket. Write exactly 3 paragraphs each separated with two new lines answering this question. The last paragraph must start with "note".
