Multi-Cloud Security : Key Things To Consider

Multi-Cloud Security : Key Things To Consider

Cyber Security and Hacking

Multiple organizations throughout the world, especially those distributed among a few countries, are traditionally using multiple on-premise data centers. However, multi-cloud environments offer a lot of benefits for the scalability and performance of digital infrastructures, that’s why they get increasingly adopted by businesses in various sectors of the economy.

Nevertheless, at the same time, cloud cybersecurity concerns rise accordingly. If a data center offers a physical entity that has its boundaries and is easier to protect, a multi-cloud structure is literally boundless. As a result, it is vulnerable to all kinds of attacks. Both specifically targeted and infecting public repositories altogether. Aiming at a broad number of victims without precise preferences.

Benefits of multi-cloud infrastructure include serving offices in multiple locations with thoughtful investments, keeping up with regulatory compliance standards, using hybrid environments combining cloud and on-premise resources. And adding security for disaster recovery.

There are just a few steps to achieving multi-cloud security to keep in mind. We will give you a quick guide. Once you know that these steps are being covered, you can rest assured that the basic requirements for multi-cloud cybersecurity are met.

Assess the Security Agility

The biggest challenge in this invisible fight for security is the need to maintain a general cybersecurity posture across different environments while avoiding vendor lock-in. In this case, it’s better to be a jack of all trades rather than an expert in a particular solution. As you know, cloud configurations and deployment policies may vary, and if you use a multi-cloud architecture, the need to stay afloat cybersecurity-wise across varying domains is pivotal. A collaborative approach with MITRE ATT&CK mapping to custom Sigma rules helps organizations stay ahead of the attackers with the support of solutions like SOC Prime’s Detection as Code platform that gives access to a continuously renewing pool of thousands of Sigma-based detections. And for instant vendor-specific translations, it is possible to use Uncoder.IO, a free online translation engine for security search queries and other content as well. 

So, it’s no surprise that variability in the digital ecosystem increases security risks because, with a multi-cloud environment, the attack surface increases exponentially. Hence, a cybersecurity strategy for effective threat awareness and mitigation of cyber-attacks also needs to employ a multi-leveled structure for applications, tools, and data.

Organizations need to consider implementing a shared security approach that will allow them to stay constantly aware of new threats and vulnerabilities. Enabling agility with a cybersecurity CI/CD pipeline is another effective step that expands security capabilities. Make sure you also promote skills inclusivity and sharing across teams. Hire networking and security people with advanced cloud knowledge, and hire cloud people with decent knowledge in the cybersecurity domain and on-premise networks.

Develop Multi-Cloud Security Best Practices

To address a multi-cloud management complexity, the organization’s security team needs to come up with an all-around data protection strategy. In the event of a data breach, all the important information has to be preserved and kept in a safe place. It should also be independent of a cloud provider to avoid vendor lock-in and possible problems if the provider itself gets breached.

The security strategy should also encompass cyber resiliency, replication, real-time threat detection, automation, archiving, and disaster recovery playbooks. Credentials and secrets safety is also important when it comes to multi-cloud environments that largely depend on microservices.

Here is a quick checklist for multi-cloud security concerns:
  • Security policies. It’s useful to isolate different workloads, users, and applications with the help of appropriate security profiles. Yet, at the same time, security policies should also be tailored for each particular use case. They usually depend on compliance standards, level of data privacy, and business context. Additionally, security policies should be synchronized to ensure the same settings across multiple clouds. Some tools allow doing it automatically.
  • Continuous maintenance. Cybersecurity scans should occur on a regular basis. Ideally, threats and vulnerabilities, even if they are new, should become detected in close to real-time conditions. Automation of security processes helps to achieve this kind of result. Any new activity like the deployment of code updates or any other change in the environment should also become precisely monitored and logged.
  • Consolidate processes. Cybersecurity practices become best performed when they aggregate the data from various sources all in one palace. For example, you want to collect and retain logs. But also raise alerts. Comply with regulations. Perform threat hunting. And proceed with remediation playbooks. If all the data becomes consolidated, parsed, and correlated in one environment. Then as a result, maintaining efficient DevSecOps becomes much easier.

According to the latest IBM research, 75% of respondents are organizations that currently use three or more solutions for securing multi-cloud environments. This tendency highlights a growing need to avoid redundancy. And moreover, ensure efficient use of all the available tools for protecting digital infrastructures and data. Starting from an overall strategy is a viable solution to obtaining a clear understanding of available action plans. Primary fields that require attention regarding security include regulatory compliance, continuous monitoring, and shared security processes.
