How to Ensure Cross-Cloud Platform Security

Organizations face threats from an increasingly hostile and interconnected world, where business risk is perceived as ever-changing. If left open, your cloud infrastructure can be infiltrated by malicious actors. In addition, local storage breaches can leak your assets to the cloud.

Data loss or theft could destroy your business, and it’s already happened to some of your competitors – if not you. First, to protect yourself from security breaches, use a multi-cloud platform manager like Sonrai Security to manage your data across various cloud services. Next, follow some simple steps below.

Use A Multi-Cloud Platform Manager

Companies with complex cloud infrastructures need platforms that can dynamically integrate all of their clouds to securely provision and scale them most efficiently. However, when deploying cloud, organizations must choose between fully cloud-native solutions or hybrid cloud solutions.

Multi-cloud platforms provide security through APIs that allow different solutions to talk to each other. It can be deployed on-premise or in a hybrid architecture across multiple servers.

Many businesses choose a hybrid cloud solution to integrate their on-premise systems with their public cloud and utilize the best of both worlds.

Implement A Multi-Cloud Policy

First, put a multi-cloud policy in place. This policy defines the data residency rules between various cloud services. You can find details of the policy in your networking services provider’s documentation, such as:

  • Inbound and outbound network connections: public IP address or network service
  • VLANs, logical network boundaries, and subnets
  • VLAN subnets and subnets
  • Access control lists and resource usage
  • Network or data location

Note: the policy should always contain the same parameters for each cloud service. The policy describes which information can be shared between different cloud services.

Install and Configure Automated Security

Ensure your security solutions support automation. For example, Sonrai Security can integrate with many security vendors, making it an excellent choice for sophisticated security solutions. It takes just minutes to integrate security solutions such as armor, Splunk, SentinelOne, Onapsis, and many more.

Using this integration, you can automate workload and network auditing, security posture and compliance management, event response management, and incident management. These are critical elements required to detect and respond to security incidents from different sources across your entire environment.

Encrypt Data

Create a default encryption policy for your cloud applications. Once the encrypted data is stored on the storage, any access to the data is logged in its encrypted container. Additionally, you need to ensure that all network traffic through your cloud is encrypted using forward secrecy protocol such as TLS.

These forward-protocol connections should also be used in your network layer access controls. Encrypt attachments In addition to encrypting network traffic, encrypting attachments used to send files over email services can help you secure your data from hackers.

For instance, a long file like a Word document that needs to be sent via email might have attachments decrypted. Encrypt sensitive documents with apps.

Implement Robust Access Controls

Access to critical cloud assets must be strictly controlled and designed to reduce the threat of data leaks or security breaches. To ensure that all cloud applications and platforms are controlled, users need to use permissions with precise control over their activities. This can be done via a set of clear, distinct user rights (GRC) which each app and platform  must implement.

Allow only authorized applications to gain access to their cloud resources. Cloud services provide APIs and SDKs for developers to quickly implement controls to define access rights.

Enable 2FA

Because cloud platforms can be a severe security risk to your business, you need an extra layer of security. No amount of security alone is sufficient. You need to apply 2FA everywhere you need to have access to your IT infrastructure.

The security has to be two-way. There are numerous ways to secure the 2FA process. Some cloud providers support multi-factor authentication (MFA), which means users need to provide two ways of proving their identity and unlock an account.

A popular way to manage 2FA is to use SMS to receive an authentication code and then submit it to their service or app for it to be accepted. If users can get this code from the phone itself, they can re-access their account without entering it again.

As a next step, build an Information Security management system and create an environment for security and information that can be activated in any future incidents. It’s like a fire alarm, but these systems can be a single point of failure, and failure could affect the whole system.
