Explanation
Customer management interfaces are the web portals or applications that allow customers to access and manage their cloud services, such as provisioning, monitoring, billing, etc. These interfaces are exposed to the public Internet and may be vulnerable to attacks such as phishing, malware, denial-of-service, or credential theft. If an attacker compromises a customer management interface, they can potentially access and manipulate the customer's cloud resources, data, and configurations, leading to computing and data compromise for customers. This can result in data breaches, service disruptions, unauthorized transactions, or other malicious activities.
