Abstract: This disclosure relates generally to the field of program slicing, and, more particularly, to a method and system for function call and variable access based relaxed backward slicing. The method discloses a slicing criterion which focuses only on functions called from an entry function. The slicing criteria uses control and data flow information to slice the given entry function with respect to functions called from the body of the entry function and eventually remove all functions not called directly or indirectly from the entry function. The variables modified by calls in the entry function are considered through side-effect while identifying control and data dependence chain within body of entry function. The proposed technique identifies partitions of functions based on the variables accessible in and functions called from the entry function. Thus, unrelated sets of functions with respect to the entry function are computed and divided into different partitions.

Abstract: Systems and methods include causing a scan by Cloud Access Security Broker (CASB) system of a plurality of users associated with a tenant in a Software-as-a-Service (SaaS) application where the scan includes any of identifying malware in content in the SaaS application and identifying confidential data in the content in the SaaS application; during the scan which is covering historical data in the SaaS application, receiving notifications of the content being actively modified by any of the plurality of users; and including the content being actively modified in the scan with the historical data. The systems and methods can further include maintaining geolocation of the any of the plurality of users; and causing the content being actively modified in the scan to be processed by the CASB system based on the geolocation.
