5. Utilize Role-Based Access Control:

Role-based access control (RBAC) is a security model that restricts access to resources based on the roles assigned to users. In RBAC, users are assigned to roles, and roles are assigned to permissions. This means that a user can only access resources that their role has been given permission to access.

RBAC is a popular security model because it is simple to understand and easy to implement. It is also flexible, because it can be customized to fit the needs of any organization.

6. Educate Employees:

It is essential to educate employees on the importance of security and the proper methods for protecting their accounts. Please make sure that they know about the risks associated with cloud applications and the need to keep their credentials secure.

Managing Application Security During the Development Process 

Managing application security during the development process is essential ensure that applications are secure and compliant with relevant standards. The development process should incorporate security requirements into the design, coding, and testing stages to ensure that applications are secure and can protect the sensitive data they store.

The development process should begin with a security assessment to identify potential security risks or vulnerabilities. This assessment should identify any gaps in the application’s security or any weaknesses that attackers could exploit. Once identified, the development team should ensure that these risks are addressed during the design and coding stages.

Secure coding practices should be implemented to help prevent common security vulnerabilities. This includes following safe coding guidelines, using secure libraries and frameworks, and avoiding using insecure coding practices. Additionally, the development team should use code review and testing processes to identify any security flaws.

So, the development team should ensure that the application is deployed correctly and configured. This includes properly configuring authentication, authorization, and access controls, and implementing secure communication protocols.
