A data integrity server for protecting systems and data, the data integrity server comprising: a processor executing instructions stored in memory, wherein the instructions cause the processor to initialize a malware detection module, a file type verification module, and a file sterilization module; the malware detection module to: (i) receive a data file for import from an external source; (ii) analyze the received data file with a plurality of anti-malware engines; (iii) determine whether the received data file comprises malware based on the analysis; and (iv) discard the received data file in response to a determination that the received data file comprises malware; the file type verification module to, in response to a determination that the received data file does not comprise malware, determine whether characteristics of header information of the received data file correspond to characteristics ofheader information of a reference data file having a same file extension as the received data file, wherein the file type verification module further to: (i) verify a file type of the received data file in response to the determination that the characteristics of header information of the received data file correspond to the characteristics of header information of the reference data file having the same file extension, and (ii) discard the received data file in response to the determination that the characteristics of header information of the received data file do not correspond to the characteristics of header information of the reference data file having the same file extension; and the file sterilization module to: in response to verifying the file type (i) modify a structure of the received data file based on the verified file type and a respective file type mathematical algorithm to transform, with minimal degradation of quality, the received data file into a sterilized data file to render malware not detected within the received data file benign; and (ii) transmit the sterilized data file to a computing device for import of the sterilized data file. a processor executing instructions stored in memory, wherein the instructions cause the processor to initialize a malware detection module, a file type verification module, and a file sterilization module; the malware detection module to: (i) receive a data file for import from an external source; (ii) analyze the received data file with a plurality of anti-malware engines; (iii) determine whether the received data file comprises malware based on the analysis; and (iv) discard the received data file in response to a determination that the received data file comprises malware; the file type verification module to, in response to a determination that the received data file does not comprise malware, determine whether characteristics of header information of the received data file correspond to characteristics ofheader information of a reference data file having a same file extension as the received data file, wherein the file type verification module further to: (i) verify a file type of the received data file in response to the determination that the characteristics of header information of the received data file correspond to the characteristics of header information of the reference data file having the same file extension, and (ii) discard the received data file in response to the determination that the characteristics of header information of the received data file do not correspond to the characteristics of header information of the reference data file having the same file extension; and the file sterilization module to: in response to verifying the file type (i) modify a structure of the received data file based on the verified file type and a respective file type mathematical algorithm to transform, with minimal degradation of quality, the received data file into a sterilized data file to render malware not detected within the received data file benign; and (ii) transmit the sterilized data file to a computing device for import of the sterilized data file. (i) verify a file type of the received data file in response to the determination that the characteristics of header information of the received data file correspond to the characteristics of header information of the reference data file having the same file extension, and (ii) discard the received data file in response to the determination that the characteristics of header information of the received data file do not correspond to the characteristics of header information of the reference data file having the same file extension; and the file sterilization module to: in response to verifying the file type (i) modify a structure of the received data file based on the verified file type and a respective file type mathematical algorithm to transform, with minimal degradation of quality, the received data file into a sterilized data file to render malware not detected within the received data file benign; and (ii) transmit the sterilized data file to a computing device for import of the sterilized data file.
