Mobile application management (MAM) is a solution that allows the organization to control and secure the approved collaboration applications and the data within them on personal devices. MAM can prevent unstructured data from being exfiltrated by restricting the ability to move, copy, or share data between applications. Multi-factor authentication (MFA) is a solution that requires the user to provide more than one piece of evidence to prove their identity when accessing corporate data. MFA can prevent data from being exfiltrated as a result of compromised credentials by adding an extra layer of security. Digital rights management (DRM) is a solution that protects the intellectual property rights of digital content by enforcing policies and permissions on how the content can be used, accessed, or distributed. DRM can prevent sensitive information in emails from being exfiltrated by encrypting the content and limiting the actions that can be performed on it, such as forwarding, printing, or copying.

In a shared responsibility model for PaaS, the customer's responsibility is OS security. PaaS stands for Platform as a Service, which is a cloud service model that provides a platform for customers to develop, run, and manage applications without having to deal with the underlying infrastructure. The cloud provider is responsible for the physical security, network security, and host infrastructure of the platform, while the customer is responsible for the security of the operating system, the application, and the dat a. The customer needs to ensure that the operating system is patched, configured, and protected from malware and unauthorized access. Verified Reference:

Fuzz testing, or fuzzing, is a software testing technique that involves providing invalid, unexpected, or random data as input to a computer program. The program is then monitored for exceptions such as crashes, or failing built-in code assertions or for potential memory leaks. This type of testing can help identify security vulnerabilities that could be exploited by malicious inputs.
