Based on analyzing a serverless function associated with a first role, a set of security permissions granted to the serverless function is identified based on the first role and a first attribute of the serverless function. A least privilege role indicating a set of least privilege security permissions for the serverless function is generated based, at least in part, on the first attribute. Based on comparing the least privilege role with the first role, it is determined if the set of security permissions granted to the serverless function is more permissive than the set of least privilege security permissions. Based on determining that the set of security permissions granted to the serverless function is more permissive than the set of least privilege security permissions, the first role is reported as over-permissive.

Identifying serverless functions with over-permissive roles

A system and methods for protecting a serverless application, the system including: (a) a serverless application firewall configured to inspect input of the serverless function so as to ascertain whether the input contains malicious, suspicious or abnormal data; and (b) a behavioral protection engine configured to monitor behaviors and actions of the serverless functions during execution thereof.

Protecting serverless applications

A system facilitates detection of malicious properties of software packages. A generic application which comprises known functionality into which a software package has been included is analyzed through a static analysis and/or dynamic analysis, which is performed based on executing the generic application in a controlled environment. The static analysis and/or dynamic analysis are performed to determine whether one or more properties associated with the software package comprise deviations from the known behavior of the generic application. Behavior deviations identified based on the static and/or dynamic analysis are associated with a score. An aggregate score is calculated for the software package based on the scores which have been assigned to the identified behavior deviations and may be adjusted based on a reputation multiplier determined based on metadata of the software package. If the aggregate score of the software package exceeds a score threshold, the software package is flagged as malicious.

Software package analysis for detection of malicious properties

A method for securing a serverless application including: (a) receiving a list of components which make up the serverless application and one or more intended usage flows of the serverless application; (b) creating and applying a security policy for each component of the serverless application, the security policy denying all access requests except from authorized components, wherein the authorized components are selected based on access requirements dictated by the one or more intended usage flows.

Securing application behavior in serverless computing

The disclosed serverless security access control system leverages static analysis information about application code and runtime information to create and assign on-the-fly transient serverless function roles. A default role can be initially assigned to serverless functions of the application. The default role allows the function to communicate with a security access broker. The access broker accesses least privilege information about an invoked serverless function and then creates and assigns a transient role to the serverless function based on that information. The short life of the role reduces and possibly eliminates the security risk of an over-permissive role. The access broker can update the least privilege information based on updated analysis of the application code and runtime information to allow flexibility and adaptation over executions.
