Introduction to OWASP Cloud-Native Application Security Top 10

OWASP Cloud-Native Application Security Top 10

With the increasing adoption of cloud computing, cloud-native application security has become a vital concern for enterprises and developers. The OWASP (Open Web Application Security Project) has been a significant contributor to the security community with its top 10 security risks. In recent years, OWASP has extended its focus from traditional application security issues to cloud-native security risks. Their latest release of the OWASP Cloud-Native Application Security Top 10 outlines the most critical security risks in cloud-native applications.

The cloud-native approach refers to building, deploying, and managing applications in the cloud environment. It involves the use of containerization, microservices, and cloud-native infrastructure to deploy and run applications. While this modern approach has numerous benefits, it also exposes applications to new security vulnerabilities. These vulnerabilities include misconfigured cloud services, container security issues, and insecure application programming interfaces (APIs), among others. Hence, it’s essential to design, develop, and deploy secure cloud-native applications to mitigate these risks.

The OWASP Cloud-Native Application Security Top 10 is a guide that helps developers and enterprises identify, prioritize, and mitigate cloud-native application security risks. The ranking order is based on the prevalence, severity, and exploitability of the risks. In this article, we will dive deep into the first risk on the list.

1. Serverless Security Risks

Serverless Security Risks

Serverless computing is a type of cloud-native computing that runs code in the cloud without managing servers. It provides developers with a platform to build applications without worrying about the underlying infrastructure. However, serverless applications face unique security risks.

One of the essential aspects of serverless computing deployment is the security of the functions. Functions are the core building blocks of serverless applications and are designed to be ephemeral, stateless and scalable. However, this also makes them vulnerable to exploitation by attackers who can manipulate the functions to perform malicious operations, such as gaining unauthorized access, stealing data, or launching denial of service attacks.

Another significant security risk for serverless applications is the dependency on third-party services. Serverless functions commonly use third-party libraries and services such as databases, authentication services, and APIs. These third-party dependencies introduce security risks that may propagate through to the serverless application and result in security incidents.

Moreover, serverless applications may also suffer from insecure configuration and permissions. Misconfigured permissions may allow attackers to execute arbitrary code, access or modify sensitive data. The lack of or inadequate logging and monitoring also hinders the detection of serverless-specific attacks or suspicious activities.

To mitigate these serverless security risks, developers and enterprises can implement several measures, such as:

  • Secure code development: Developers should follow secure coding practices such as validating inputs, restricting permissions, sanitizing outputs, and performing strict function parameter validation.
  • Thorough testing and validation: Comprehensive testing should be done to identify application vulnerabilities. This testing can include coding reviews by peers, automated code scanning tools, and regular penetration testing.
  • Implementing strict access controls and permissions: Access and permissions should be granted based on the principle of least privilege. Developers should also avoid hardcoding access keys, secrets, and credentials in the code.
  • Logging and monitoring: Security logs and metrics should be collected and monitored to detect suspicious activities. Developers should also implement real-time alerting mechanisms to notify security teams of potential security incidents.
  • Managing third-party dependencies: Developers should carefully select and review third-party libraries and services used by serverless applications. Checking for library vulnerabilities and maintaining up-to-date dependencies should be an essential process.

Cloud-native applications are becoming increasingly popular due to the numerous benefits they offer. These applications are designed to run on cloud platforms, allowing organizations to take advantage of the scalability, flexibility, and cost-effectiveness of cloud computing. However, with the rise of cloud-native applications, the security risks have also increased. Sensitive data is being stored and transferred through these applications, and a security breach could have catastrophic consequences for an organization. Therefore, it is imperative that organizations prioritize the security of their cloud-native applications.

The Risks of Inadequate Cloud-Native Application Security

The Risks of Inadequate Cloud-Native Application Security

Organizations that fail to adequately secure their cloud-native applications are putting themselves at risk of cyberattacks, data theft, and other security breaches. Hackers are constantly looking for vulnerabilities in these applications to exploit. If they manage to gain access to an organization’s sensitive data, they can use it for nefarious purposes such as identity theft, financial fraud, or corporate espionage. In addition to the financial losses and reputational damage, organizations may also face legal liabilities and regulatory penalties in the event of a security breach.

One of the biggest risks of inadequate cloud-native application security is the lack of control over the security measures. Traditional security measures such as firewalls and intrusion detection systems are not always sufficient for securing cloud-native applications. Organizations need to take a multi-layered approach to security that includes strong access controls, threat detection, and incident response capabilities. They also need to ensure that their cloud provider is using the latest security technologies and adhering to industry standards.

The Benefits of Cloud-Native Application Security

The Benefits of Cloud-Native Application Security

Properly securing cloud-native applications can bring numerous benefits to an organization. Firstly, it can help to prevent security breaches, data theft, and cyberattacks, thereby safeguarding an organization’s sensitive data and intellectual property. Secondly, it can help to maintain compliance with industry regulations and standards, preventing financial and legal penalties. Thirdly, it can help to maintain the trust and confidence of customers, partners, and stakeholders, which is essential for business continuity and growth. Lastly, it can help to reduce the costs associated with maintenance and recovery from security breaches, providing a significant return on investment.

To conclude, cloud-native applications are transforming the way organizations do business. However, with the benefits come increased security risks that need to be addressed. Inadequate cloud-native application security can have severe consequences for an organization, which is why it is crucial to prioritize security in the cloud. By implementing a multi-layered approach to security and staying up-to-date with the latest security technologies and industry standards, organizations can reap the benefits of cloud-native applications while keeping their sensitive data secure.

Common Vulnerabilities in Cloud-Native Applications

Common Vulnerabilities in Cloud-Native Applications

Cloud-native applications are revolutionizing the way businesses are run, but they also pose serious security risks. As more applications are developed and deployed in cloud environments, it is essential to recognize and address potential vulnerabilities. Here are the top three common vulnerabilities on cloud-native applications:

1. Unsecured APIs

Unsecured APIs

In cloud-native applications, APIs (Application Programming Interfaces) are used to communicate between different microservices within the application. However, if these APIs are not properly secured, they can be vulnerable to hacking attacks. API security is often neglected because developers may prioritize the functionality of the application over its security. The consequences can be disastrous if an attacker gains unauthorized access to the API, as they can manipulate data or gain access to the backend systems. To prevent these attacks, it is important to implement security measures such as authentication, encryption, and authorization to ensure that only authorized users have access to the APIs.

2. Lack of Visibility and Control

Lack of Visibility and Control

Cloud environments offer rapid development and deployment, but they also bring along new security challenges such as lack of visibility and control. It is difficult to track the movement of data and identify the source of a security breach in cloud-native applications. Additionally, many applications are deployed using container orchestration platforms like Kubernetes, which adds even more complexity to security management. To overcome these challenges, it is important to use appropriate security tools that provide visibility across the entire application infrastructure, from the cloud platform to the container environment, and have robust security monitoring in place for early detection of threats.

3. Inadequate Data Protection

Inadequate Data Protection

Data breaches are a major concern for any cloud-native application. These breaches can be caused by both internal and external threats, but inadequate data protection measures can worsen the situation. Inadequate data protection practices include insufficient encryption, unsecured data storage, and weak access control policies. Many developers often assume that their cloud provider will handle these security measures but fail to realize that data protection is a shared responsibility. Developers should prioritize implementing strong encryption algorithms to protect sensitive data and adopt proper access control policies to ensure that only authorized users have access to the data. Additionally, data backup and contingency plans should be established to mitigate the harm in case of a security breach.

In conclusion, cloud-native applications have changed the way software development is done, but they come with specific security challenges. To protect cloud-native applications from threats, it is essential to be aware of common vulnerabilities and take proactive measures to counter them. Employing a defense-in-depth security approach that involves multiple layers of security controls can go a long way in providing robust security for cloud-native applications.

Best Practices for Enhancing Cloud-Native Application Security

Cloud-Native Application Security

In order to enhance the security of cloud-native applications, there are several best practices that organizations should follow:

1. Implement Zero-Trust Security

With zero-trust security, every user and device must be authenticated before they are granted access to the application. This means that even if a user is accessing the application from a trusted device or network, they will still need to be verified before being granted access. By implementing zero-trust security, organizations can ensure that only authorized users have access to their applications, reducing the risk of data breaches and other security incidents.

2. Use Multi-Factor Authentication (MFA)

Multi-factor authentication (MFA) requires users to provide additional evidence of their identity before being granted access to an application. This can include something they know, such as a password, something they have, such as a security token, or something they are, such as a biometric scan. By using MFA, organizations can increase the security of their applications, as even if a user’s password is compromised, the attacker will still need to provide additional evidence of identity before being granted access.

3. Encrypt Data in Transit and at Rest

Data encryption is an essential component of cloud-native application security. In order to minimize the risk of data breaches, organizations should encrypt all data in transit and at rest. This means that any data transferred between servers, or stored on disks or in databases, should be encrypted to protect it from attackers. Encryption keys should also be stored securely, ideally in a separate server or environment, to prevent them from being compromised.

4. Perform Regular Vulnerability Scanning and Penetration Testing

Penetration Testing

Regular vulnerability scanning and penetration testing can help organizations identify and address security vulnerabilities before they can be exploited by attackers. Vulnerability scanning involves using automated tools to scan an application for known vulnerabilities, such as outdated software or misconfigured servers. Penetration testing, on the other hand, involves attempting to exploit vulnerabilities in a controlled environment to determine whether they can be used to gain unauthorized access to the application.

By performing regular vulnerability scanning and penetration testing, organizations can identify and address security flaws before they can be exploited by attackers. This can help to minimize the risk of data breaches and other security incidents, allowing organizations to focus on delivering high-quality, secure applications to their users.

5. Implement Access Controls and Segmentation

Access controls and segmentation can help to minimize the risk of data breaches and other security incidents by limiting the amount of data and resources that can be accessed by individual users and devices. Access controls should be implemented at the application and infrastructure levels, and should include role-based access control (RBAC) and attribute-based access control (ABAC) mechanisms to ensure that only authorized users have access to sensitive resources.

Segregation of duties is also important, as it can help to prevent a single individual from having unchecked access to critical resources. By implementing access controls and segmentation, organizations can help to ensure that critical data and resources are protected from unauthorized access, minimizing the risk of data breaches and other security incidents.


Enhancing the security of cloud-native applications is essential for organizations that want to deliver high-quality, secure applications to their users. By following best practices like implementing zero-trust security, using MFA, encrypting data in transit and at rest, performing regular vulnerability scanning and penetration testing, and implementing access controls and segmentation, organizations can help to ensure that their applications are protected from attackers and other security threats.
