The next greatest practices are basic pointers and don’t symbolize a whole safety answer. These greatest practices is probably not applicable or adequate on your setting, so use them as useful issues slightly than prescriptions.
Finest Follow 1 – Use Information Safety with Amazon Transcribe
Amazon Transcribe adheres to the AWS Shared Duty Mannequin, which separates AWS duty for safety within the cloud from the client’s duty for safety inside the cloud.
AWS is answerable for securing the worldwide infrastructure that runs all AWS Clouds. Prospects are answerable for sustaining management of the content material hosted on this infrastructure. This content material consists of safety configuration and administration duties for the AWS companies she makes use of. For extra details about information privateness, see our Information Privateness FAQ.
Defending your information in transit
Information encryption is used to make sure the confidentiality of information communications between your utility and Amazon Transcribe. Using sturdy encryption algorithms protects your information throughout transmission.
Amazon Transcribe can function in one in all two modes:
- streaming transcription Allows transcription of media streams in actual time
- Batch switch job Permits transcribing audio information utilizing an asynchronous job.
In streaming transcription mode, the consumer utility opens a two-way streaming connection over HTTP/2 or WebSocket. When your utility sends an audio stream to Amazon Transcribe, the service responds with a real-time textual content stream. Each HTTP/2 and WebSocket streaming connections are established over Transport Layer Safety (TLS), a broadly accepted cryptographic protocol. TLS makes use of AWS certificates to offer authentication and encryption of information in transit. We advocate utilizing TLS 1.2 or later.
Batch transcription mode requires you to first place your audio information into an Amazon Easy Storage Service (Amazon S3) bucket. A batch transcription job is then created in Amazon Transcribe that references his S3 URI for this file. Amazon Transcribe in batch mode and Amazon S3 each use HTTP/1.1 over TLS to safe your information in transit.
All requests to Amazon Transcribe over HTTP and WebSockets have to be authenticated utilizing AWS Signature Model 4. We advocate that you just additionally use Signature Model 4 to authenticate HTTP requests to Amazon S3, though some AWS Areas additionally permit authentication with the older Signature Model 2. . Your utility requires legitimate credentials to signal API requests to AWS companies.
Defending your information at relaxation
Amazon Transcribe in batch mode makes use of an S3 bucket to retailer each enter audio information and output transcription information. The client makes use of her S3 bucket to retailer the enter audio information, so we extremely advocate enabling encryption on this bucket. Amazon Transcribe helps the next S3 encryption strategies:
With both methodology, buyer information is encrypted when written to disk and decrypted when accessed utilizing 256-bit Superior Encryption Customary (AES-256) GCM, one of many strongest block ciphers obtainable. can be executed. When utilizing SSE-S3, encryption keys are managed. It’s rotated periodically by the Amazon S3 service. To boost safety and compliance, SSE-KMS offers you management over your encryption keys by AWS Key Administration Service (AWS KMS). AWS KMS offers extra entry controls as a result of encrypting and decrypting objects in an S3 bucket configured with SSE-KMS requires permission to make use of the suitable KMS key. SSE-KMS additionally offers prospects with an audit path function that information who used her KMS key and when.
Output transcriptions will be saved in the identical or totally different customer-owned S3 buckets. On this case, the identical SSE-S3 and SSE-KMS encryption choices apply. Another choice for Amazon Transcribe output in batch mode is to make use of a service-managed S3 bucket. The output information is then positioned in a safe S3 bucket managed by the Amazon Transcribe service, which offers a short lived URI that you need to use to obtain the transcript.
Amazon Transcribe makes use of encrypted Amazon Elastic Block Retailer (Amazon EBS) volumes to quickly retailer buyer information throughout media processing. Buyer information is cleaned in each full and failed instances.
Finest Follow 2 – Talk over a non-public community path
Many shoppers depend on in-transit encryption to securely talk with Amazon Transcribe over the Web. Nevertheless, relying in your utility, information encryption in transit alone is probably not adequate to fulfill your safety necessities. In some instances, it’s possible you’ll need to forestall information from traversing public networks such because the Web. You may additionally must deploy your utility in a non-public setting that’s not linked to the Web. To fulfill these necessities, use interface VPC endpoints powered by AWS PrivateLink.
The next structure diagram exhibits a use case the place an utility is deployed to Amazon EC2. The EC2 cases working your utility don’t have entry to the web and talk with Amazon Transcribe and Amazon S3 by interface VPC endpoints.
In some eventualities, purposes that talk with Amazon Transcribe could also be deployed in on-premises information facilities. You might have extra safety or compliance necessities that mandate that information exchanged with Amazon Transcribe should not traverse public networks, such because the Web. On this case, you need to use a non-public connection by way of AWS Direct Join. The next diagram exhibits an structure that permits on-premises purposes to speak with Amazon Transcribe with out connecting to the web.
Finest Follow 3 – Redact delicate information if obligatory
Relying in your use case and regulatory setting, it’s possible you’ll must take away delicate information from transcripts and audio information. Amazon Transcribe helps figuring out and modifying personally identifiable data (PII) similar to identify, handle, and social safety quantity. This function permits a buyer to attain Cost Card Trade (PCI) compliance by modifying his PII similar to credit score or debit card quantity, expiration date, and 3-digit Card Verification Code (CVV). Will probably be. In transcripts containing redacted data, the PII can be changed with a placeholder in sq. brackets indicating the kind of his PII that was redacted. Streaming transcription helps extra options that solely determine PII and label it with out modifying. The kind of PII edited by Amazon Transcribe differs between batch transcription and streaming transcription. For extra data, see Enhancing PII in Batch Jobs and Enhancing or Figuring out PII in Actual-Time Streams.
The specialised Amazon Transcribe Name Analytics API consists of built-in performance to edit PII in each textual content transcripts and audio information. This API makes use of specialised speech-to-text and pure language processing (NLP) fashions which can be particularly educated to grasp customer support and gross sales calls. For different use instances, you need to use this answer to edit PII from audio information utilizing Amazon Transcribe.
Extra Amazon Transcribe safety greatest practices
Finest Follow 4 – use The position of IAM For purposes and AWS companies that require Amazon Transcribe entry. When utilizing roles, there isn’t any must distribute long-term credentials similar to passwords and entry keys to EC2 cases and his AWS companies. IAM roles can present short-term permissions that an utility can use when making requests to his AWS sources.
Finest Follow 5 – use Tag-based entry management. You need to use tags to regulate entry inside your AWS account. Amazon Transcribe lets you add tags to transcription jobs, customized vocabularies, customized vocabulary filters, and customized language fashions.
