Cloud Security Posture Management (CSPM) solutions help organizations monitor and manage cloud infrastructure security, ensuring compliance with industry standards. They continuously assess for potential risks and vulnerabilities, providing insight and guidance to maintain a secure cloud environment.
As cloud utilization increases, CSPM solutions are indispensable in maintaining robust cloud security. They provide automated tools for identifying misconfigurations and compliance violations...
You have many attack vectors.
Firstly, there are the attack vectors that are part of your application and environment but these will be the same independent of where you are.
Beyond that you have the following ones:
1) Anybody with access to the PaaS infrastructure either internal or external.
2) Accidental mistagging of data (think of accidentally setting an S3 bucket as public).
3) The provider monetizing your data (take a look at the troubles currently surrounding Oracle)
4) large cloud providers are subject to constant attacks because they are well-known addresses.
Private systems are still subject to attacks but not on the same level of intensity or as often by serious hackers.
The best solution for PaaS protection is always native tools... from the CSP.
