Key Points
- Shared Responsibility Model For Cloud Applications: Cloud providers secure infrastructure, but organizations are responsible for managing access, configurations, and protecting their own data.
- Insecurity of Default Settings: Default settings and native protections require proper configuration, continuous monitoring, and active management to prevent vulnerabilities.
- Layered Approach to Security: Effective cloud data protection combines identity and access management (IAM), encryption, secure configuration, monitoring, and backup/recovery.
- IAM and Its Role in Cloud Data Security: Practices like multi-factor authentication, role-based access, and removing inactive accounts significantly reduce unauthorized access risks.
- Human Risk and Cybersecurity: Even small configuration mistakes or untrained users can lead to large-scale data exposure, making monitoring, auditing, and user education critical.
The use of cloud and SaaS applications has become a mainstay in many modern office environments. Take Microsoft 365 and Google Workspace as examples: Both are widely used to store and manage business data. While these applications are indubitably beneficial, the question of data security will always remain.
Generally, most SaaS and cloud applications provide built-in security features; however, these features do not eliminate the need for proper configuration and ongoing protection. This is why organizations still need to manage access, monitor usage, and apply security controls to maintain SaaS data security.
This article provides an overview of how to protect data on your cloud applications in SaaS environments using proven practices.
Cloud application data security: How-to and best practices
Protecting your data in the cloud doesn’t happen in an instant. It requires multiple layers of control, ensuring that when one measure fails, another covers it. While there is no definitive step-by-step process for protecting cloud data, there are best practices across the board that you can implement.
These practices include:
Identity and access management
Identity and access management (IAM) helps organizations control access to resources in their organization. For SaaS and cloud applications, applying IAM practices enhances security by allowing select users or roles to have access only to the data they need.
Key practices include:
- Enforcing multi-factor authentication
- Using role-based access instead of full permissions
- Removing inactive accounts
Depending on the structure of your organization, you may need or prefer to add more security measures.
Secure configuration
Configuring the default settings of your system is critical to defend your security configurations from threats. For SaaS and cloud applications, this means:
- Restricting public file sharing to ensure data remains within the organization only
- Reviewing default permissions
- Limiting external access
These actions help prevent data breaches, especially from external sources.
Encryption
Encryption protects data by ensuring that the data is unreadable to unauthorized users. This adds a layer of security to your organization’s data and privacy. Encryption is particularly important in cloud security as it ensures that files remain protected while they move or are stored in cloud-based applications.
Monitoring and auditing
Tracking user activity and access logs, setting alerts for unusual behavior, and regularly reviewing audit logs are good practices in general, as it helps IT teams to easily spot and prevent potential threats.
Backup and recovery
The final layer involves ensuring easy data recovery in case of data loss or breach. This is where data backup and recovery come in. Establishing good backup practices with your SaaS and cloud data is necessary so your organization doesn’t lose any critical data.
Key practices include:
- Using automated backups for critical data
- Maintaining independent copies outside the platform
- Testing recovery processes
With each step working together, this layered approach to cloud data security helps organizations strengthen their security posture and prevent data loss.
Securing sensitive data in SaaS applications
Working with sensitive data requires a stricter approach as it reduces the risk of exposure.
In SaaS and cloud applications, applying the following measures is highly recommended when dealing with sensitive data:
- Classifying data based on sensitivity
- Restricting access to critical information
- Monitoring access to sensitive records
- Limiting integrations with sensitive data
- Applying additional controls for regulated data
What makes cloud app security and SaaS data security different?
Cloud-based applications and SaaS applications work under a shared responsibility model; this means that:
- Providers secure the infrastructure
- Customers manage access, configuration, and data protection
Unlike traditional environments, which relied heavily on direct control over security protocols, managing cloud application security leans more into a layered and proactive approach.
To be more precise, you can go through some of the key differences between data security in cloud and traditional environments:
| Aspect or feature | Traditional environments | Cloud-based environments |
| Access patterns | Typically on-premise, limited remote access | Remote access from multiple devices and locations |
| Security focus | Network perimeter and physical controls | Identity, access management, and permissions |
| Third-party integrations | Minimal or controlled integrations | Heavy reliance on third-party applications and services |
| Configuration complexity | Typically more static and predictable | Dynamic, must consider the risk of large-scale exposure due to small misconfigurations |
| Security approach | Usually more reactive and perimeter-based | Usually more proactive and relies heavily on monitoring and configuration management |
Common misconceptions about cloud app security
Default settings are sufficient
Default settings refer to the standard, pre-configured security measures that come with a software or application. While these default settings were designed to provide a basic layer of security, they don’t always cover all the needs of an organization. In addition, it is always a good idea to configure such settings to mitigate any risks associated with them.
Internal users do not pose a risk
Human error is still heavily related to cybersecurity risks. Untrained or unaware users can unintentionally expose organizations to risks such as phishing attacks, credential theft, accidental data leaks, weak password practices, or improper handling of sensitive information. Continuous training and education, as well as the encouraged use of best security practices, are necessary to minimize potential risks from internal users.
Cloud providers fully secure your data
Cloud and SaaS applications operate under a shared responsibility model. This means that cloud providers secure infrastructure, but customers remain responsible for how they use the application, including how they handle security configurations, access, and data. While cloud providers are required to provide infrastructure that is secure, users still need to actively manage their data to ensure full security.
SaaS apps are inherently secure
SaaS applications also operate under a shared responsibility model, which is why it’s false to claim that they are inherently secure. While most SaaS applications will have a relatively robust set of security measures, users are still responsible for handling data and configurations within their organizations.
Backup is unnecessary in cloud environments
While several cloud service providers offer storage for your data, it doesn’t necessarily mean that your data is inherently protected from cyberattacks, application misconfiguration, or simple human error. If critical data is lost in a cloud environment and an organization has no way of recovering it, this can impact their business operations and even public trust. Having independent backup software allows organizations to easily recover from data loss and maintain their security.
Protect your data by securing SaaS and cloud data
Protecting data in cloud apps requires a combination of access control, encryption, monitoring, and backup. While cloud providers offer foundational security, organizations must actively manage configurations and risks to ensure data remains protected.
