Cyberattacks cripple various enterprises and businesses regularly. Some trades and industries face malicious attempts more than others, but the extent of the damage for any industry can be substantial. Security is a concern for organizations since operational integrity is what keeps a business afloat. Cloud-native has helped organizations implement zero-trust security measures with hybrid cloud and multi-cloud architectures. The need for securing data while at rest and in transit requires an added protection layer.
Data Encryption is essential to protect sensitive and private data. You can use multiple algorithms to encrypt data for protection, such as DES, AES, and RSA. Cloud systems can implement automatic data encryption and decryption based on data transmission demands and data sensitivity.
After shifting to the cloud, organizations used cloud storage to store large files and databases. Storage solutions, such as Alibaba Cloud Object Storage Service (OSS), provide unlimited storage and identity-based authentication using Alibaba Cloud RAM. The deep integration offered by Alibaba Cloud provides seamless user access.
Information and data security are a primary concern for organizations. Gartner predicted, “The global information security market is forecast to grow at a five-year CAGR of 8.5% to reach $170.4 billion in 2022. Technology product managers will see new spending driven by regulations and increased awareness as organizations’ needs evolve to address more complex threats.”
In this article, we will explain Alibaba Cloud Data Encryption Service and its usage scenarios.
Alibaba Cloud Data Encryption Service provides hardware security modules (HSM) over cloud-hosted hardware. Hardware security modules are hardware devices that process encrypted data (cryptographic operations) using encryption keys. Some of the primary benefits of Alibaba Cloud Data Encryption Service are listed below:
Alibaba Cloud Data Encryption Service uses encryption keys to protect your data with hardware-based devices that allow you to access HSM instances within Alibaba Cloud Virtual Private Cloud (VPC). These instances are tamper-resistant and enable a single-tenant access system to protect your encryption keys. The Data Encryption Service also allows custom application mapping using industry-standard APIs, including JCE.
The Data Encryption Service is a hosted service that works with any other Alibaba Cloud solution. Some of the Data Encryption Service usage scenarios are listed below:
In this scenario, you can encrypt sensitive data and business secrets with the HSM integration in your application architecture.
Financial services are prone to cyberattacks. Financial motives are the primary reason for cyberattacks.
Risk Based stated, “Data breaches exposed 36 billion records in the first half of 2020.”
Let’s take a look at the Data Encryption Service architectural flow for financial systems on the chart below:
In this scenario, all of the online payments, card-based payments, app-based payments, and POS payments use a frontend system comprised of a settlement system that takes care of financial books, a payment system that processes the incoming payment, and a financial system to forward incoming and outgoing payments to the settlement system. All of these systems are covered using a proxy for added security measures. HSM issues the encryption keys at the backend to help with data security while in transit.
The strictest security and compliance requirements within the financial structure will ensure payment integrity and confidentiality during data in transit and at rest.
Websites working with the secured HTTP/HTTPS protocol use a public-private key pair. Each session uses a public key certificate to establish a secure HTTPS session for each client. Alibaba Cloud Data Encryption Service allows your SSL offloading directly with HSM by generating private keys. Processing from a web service allows SSL offloading without consuming any web server resources, maintaining the availability and efficiency of the web server.
The Data Encryption Service is available to all Alibaba Cloud users. You can use HSM to perform multiple operations, such as SSL offloading, TLS web server processing, transparent data encryption, and sensitive and financial data encryption. Cloud data must be secured when in transit and at rest to ensure data integrity. Alibaba Cloud Data Encryption Service lets you secure the most important aspect of your organization – data.
