Organizations turn to multi-cloud strategies for various reasons. One common goal is reducing dependency on one provider while decreasing the risk associated with localized hardware failure, which could have catastrophic results on business operations.
Multi-cloud environments present unique security challenges, prioritizing integration, and automation to minimize complexity while maintaining an acceptable security posture.
Multi-cloud security requires organizations to establish consistent and scalable processes for key cloud platform practices like deployment, access control, and monitoring. Governance is also essential; organizations must devise methods of ensuring that an approved version of an app runs in all environments to avoid data loss and performance issues due to different versions being deployed on various environments.
When operating in a multi-cloud environment, it is imperative to view the configuration and security status of all cloud platforms through one dashboard. This enables organizations to identify any gaps in defenses which cybercriminals may exploit. Incorporating security into the DevOps process allows developers to follow best practices when creating secure apps while decreasing vulnerabilities by automating threat detection processes and decreasing hiding places where cybercriminals could lurk.
One of the major obstacles to adopting multi-cloud is integration between cloud environments. This occurs because security tools used by various providers do not easily interact with each other, leading to inconsistencies between policy enforcement and visibility across environments. Furthermore, organizations often only have limited security talent available to manage multi-cloud environments due to limited staff available to manage them effectively.
Solution: Multicloud solutions explicitly designed to provide unified management, end-to-end visibility and control, advanced threat prevention, and defense capabilities are necessary for an ever-evolving multi-cloud environment. These solutions will be capable of meeting security challenges posed by different cloud architectures, network constructs, and built-in security tools that create an unpredictable security posture. Organizations will benefit from adopting this strategy as it allows them to safeguard workloads regardless of where they reside and grant users appropriate access levels. They can also utilize most minor privilege access policies consistently and incorporate security into DevOps processes so developers can ensure they adhere to secure coding practices.
2. AutomationOrganizations should seek to limit potential human errors as much as possible in multi-cloud environments, including using a centralized cloud management solution with visibility and control across multiple clouds and AI functions to protect themselves against new threats as they emerge. This may mean using separate platforms for managing security settings - rather than this solution's multiple cloud configuration management solutions offering visibility and control from various locations - instead, invest in one centralized solution which provides visibility and control from one central place - this way, organizations can protect themselves against unexpected events that threaten business continuity.
Automating as much of your process as possible is one way to increase security, whether that means setting up multiple instances with identical configurations across various clouds or scanning for and closing off unsecured ports or components; automating will save both time and effort while helping minimize risks related to errors or vulnerabilities.
When automating your multi-cloud infrastructure, select a framework that supports various authentication models and lets you centrally define accounts, roles, and policies. Furthermore, choose one that automates patching and upgrading software while respecting its workload, environment, and possible dependencies.
A tool will provide a centralized dashboard to access inventory, audit, and compliance reports. It should also detect misconfigurations and alert you when security settings have been altered. Furthermore, it allows for the quick creation of consistent multi-cloud segmentation policies about N/S and E/W traffic in segments implementing and optimizing zero trust architecture that enforces the least privilege access.
As soon as you implement a centralized cloud security management solution, be sure to monitor and test it regularly - this includes performing vulnerability assessments and penetration tests - so as soon as anything weak in your multi-cloud environment surfaces, you can address it and take corrective actions before they become threats to your business.
3. ComplianceAs organizations adopt multi-cloud architectures to take advantage of the flexibility and scale offered by cloud service providers, it is equally essential that they establish a strategy to meet regulatory and compliance requirements. This requires taking a comprehensive risk identification and assessment approach, integrating security tools across environments, and maintaining consistent access controls.
Multi-cloud security becomes more complicated as more service providers join the fray. A single infrastructure platform may use various hardware configurations and operating systems; their approach to configuring services like software-defined networking, data storage, and code/container storage may vary significantly between providers, making it challenging to utilize one monitoring and management tool across all clouds due to false alerts or incomplete coverage due to various configurations.
Prioritize cloud platforms that boast the highest security and compliance standards, as these should become your go-to solutions when dealing with work that must meet specific regulations - for instance, data sovereignty laws across multiple jurisdictions - making choosing an optimal option simpler while helping reduce risks like data breaches or regulatory penalties.
4. SecurityDeveloping a multi-cloud security strategy begins by identifying your organization's most essential assets and data to protect and how you will manage these. This may involve creating and implementing controls that reduce risks while testing them regularly and preparing an incident response plan.
Management of a multi-cloud environment can be challenging, and platform inconsistencies can open blind spots for attackers. When your architecture becomes increasingly complex, the greater the possibility for human error. This is particularly evident when each platform has different security models, compliance obligations, best practice frameworks, or names for similar conceptual objects - potentially leading to inconsistencies within a unique environment and between environments that create blind spots for the attack.
Security must be prioritized across your multi-cloud by all cybersecurity and IT operations teams. A consistent management dashboard and set of tools are vital for maintaining visibility over all deployments, including any changes in security settings for each platform. A unified threat protection solution such as SIEM + XDR provides real-time forensic analysis to identify threats and respond appropriately quickly.
Consistency is of utmost importance in multi-cloud environments, from standardizing security policies and configurations across platforms to streamlining processes that occur on them, such as deploying new workloads or changing existing ones. Doing this reduces the number of buttons and levers for engineers to operate, which could result in errors.
Integrating security guardrails into DevOps toolchains is also key when working in multi-cloud environments, helping bridge the visibility gap between cybersecurity and IT operations teams and ensuring consistent workload deployment and configurations. Tufin offers an easy integration SaaS solution, automatically translating access requirements for application-critical connectivity into firewall and router policy changes - eliminating manual prep tasks while still meeting continuous compliance.
