Cure53, Dr.-Ing. M. Heiderich, M. Wege, MSc. R. Peraglie, J. Larsson Index Introduction Scope Test Coverage Identified Vulnerabilities DAP-01-002 WP2: Insufficient context separation leads to RCE software complex1. Carried out by Cure53 in summer 2020, the project entailed comprehensive penetration test and source code audit of the Dapr scope. In terms of resources, the project was assigned to encompassed penetration tests against Dapr integration and setup. The Cure53 team relied on a fully installed Kubernetes cluster, complete with sample applications that needed to be penetration-tested. The

continues a security-driven cooperation between Cure53 and Dapr, reporting on the findings of a penetration test and source code audit against the Dapr software. In addition to shedding light on the state requested by Microsoft and carried out by Cure53 in late January and early February 2021. As noted, this test is a follow-up to the project reported as DAP-01, which was a large-scale and comprehensive (WPs) were delineated: • WP1: Thorough source code audit of the latest Dapr version • WP2: Penetration tests targeting the Dapr integration and setup • WP3: Retesting of issues spotted in June 2020

a safe combination is known to an adversary, the strongest safe provides no security against penetration. Similarly, poor key management may easily compromise strong algorithms.” NIST SP 800-57, Recommendation

framework and comes up with the following advantages:  Larger community support.  Easy to test.  Keras neural networks are written in Python which makes things simpler.  Keras supports the required information from the data.  Split data: Split the data into training and test data set. Test data will be used to evaluate the prediction of the algorithm / Model (once the machine learn) existing training and test data)  Evaluate model: Evaluate the model by predicting the output for test data and cross- comparing the prediction with actual result of the test data.  Freeze
