Managing Multi-Cloud Security

 In Security

Digitization has pushed the boundaries of innovation. Industry after industry has been affected by the digital disruption, making them rethink and re-imagine the way they need to work. It’s safe to say that digitization has enabled industries to wake up from their complacent state and adopt the latest technology or face extinction. One such technology that has revolutionized business is cloud technology. Multi-cloud systems help businesses to securely store vital information off-premises. Multi-cloud is all the rage now owing to the range of benefits – diversification lowers the risk rates and working with many cloud service providers (CSPs) helps the business have their pick of the latest innovations.

But the flip side of digitization is that the attackers too have upgraded their arsenal. Cloud has started facing cybersecurity threats, as more and more proprietary information is stored in private, public and multi-cloud environments. So much so that now even virtual machines, can be compromised.

How to ensure multi-cloud security?

Multi-cloud environment consists of a combination of multiple public clouds and private cloud along with direct connect facility from a service provider to on-premises private cloud. So essentially, for multi-cloud security to be strengthened, your private and public clouds need to be secured, along with all the layers –  Perimeter Network and Host, Application, Endpoint and Data.

To ensure that organizations’ IT systems are secure and adhere to compliance requirements, cloud audits are conducted at regular intervals. The problem is that the sheer breadth of the ecosystem causes businesses to employ tons of security tools, provided by the numerous cloud service providers and platforms. In our previous post, we had researched and presented the various security tools available in the market for these different layers, and we believe that it is imperative to select and implement the right kind of tools and products for multi cloud environment.  

Security Services in Azure vs AWS

The two major cloud service providers also provide various security features. Here’s a quick study of the security features provided by Azure and AWS


AWS Inspector Azure Security Centre Automated security assessment services that improve application security and compliance. Automatically assess applications for vulnerabilities.
Web Application Firewall Application Gateway Web Application Firewall A firewall that protects web applications from common web exploits. Users can define customizable web security rules.
AWS Multi-Factor Authentication Azure Multi-Factor Authentication Security mechanism that enables user to quickly login with a simple, yet secure process.  It comes with a range of verification options that can be configured as per user preferences.
Server-side Encryption Azure Storage Service Encryption Compliance features that help organization encrypt data, safeguard them and adhere to legal regulations.
Key Management Service Key Management Service Provides security solution and works with other services by providing a way to manage, create, and control encryption keys stored in hardware security modules.

Penetration Testing

As an initiative to help organizations verify the security of their cloud setup, Microsoft Azure and Amazon Web Services provide penetration testing services, which enable them to run the following tests:

  • Test on endpoints to uncover top 10 OWASP (Open Web App Security Project) vulnerabilities
  • Fuzz testing of endpoints
  • Port scanning of endpoints

How does CoreStack help in managing multi-cloud security?

  • Security Health Dashboard – CoreStack’s Security Health Dashboard lets you view the health of your cloud security settings. You get immediate alerts in case of breaches and can take remedial actions
  • Access Control – Corestack provides privileged system access mechanism which demarcates visibility rights for various stacks of information.  This ensures that individuals access only what they are privileged to access
  • Security Operations Automation – Corestack provides automation scripts for deploying agents and configuring them in various inventories across cloud
  • ment of agents The tool automates compliance-based actions such as backups, thereby reducing the risk of data loss and human error.
  • Security Policies – Datalog driven Policy mechanism enables to set enterprise level policies for various components in Multiple Cloud Environment. Alerts, Notification or Remedial actions are allowed to be configured for Policy violations
  • Cloud and Security Tool Chaining – Cloud Secops are realized through chaining the provisioning, deployment, security assessment activities across multiple clouds and Security tools using Corestack Blueprint

    Thank you for an important article on managing multi-cloud security. Definitely going to try CoreStack in order to secure my apps in the cloud. Should I also add the layer of two-factor authentication for the same?
