Managed services will offer some level of security, like updating and securing the underlying hardware which runs application code. However, the development team are still responsible for many aspects of security in the system. Ensure developers understand what security will be their responsibility based on tool selection. Likely the following will be partially or wholly the responsibility of the developer Authentication and authorization Logging and monitoring Code security (OWASP Top 10) Third-party library patching Refer to the documentation provided by the cloud service provider to understand which aspects of security are the responsibility of each party, based on the selected service.
