Abstract
Device, computer program product and method for checking properties of resources, wherein a checking device for checking properties of resources of a web server includes a calculation unit for calculating an identifier identifying a particular resource using the particular resource, a detection unit for detecting a license requirement for the particular resource using the calculated identifier, and a determination unit for determining an existing license for the web server in the case of a license requirement detected for the particular resource using the calculated identifier, such that unauthorized posting of a particular resource to a web server can be easily detected and prevented.
Claims17
A checking device for checking properties of files of a web server comprising an image file, said properties of the files being checked within a programmable logic controller (PLC) to prevent unauthorized access of a client to the web server, comprising:
- a calculator for calculating an identifier identifying a particular file of the web server comprising the image file utilizing the particular file comprising the image file;
- a detector for detecting, within the PLC, a license requirement for the particular file of the web server comprising the image file utilizing the calculated identifier;
- and
- a license determiner for determining, within the PLC, an existing license for the web server in cases of a license requirement detected for the particular file of the web server comprising the image file utilizing the calculated identifier;
- wherein access to the web server associated with the PLC is prevented when a license requirement has been detected and the license for the web server associated with the PLC could not be determined.
A method for checking properties of files of a web server comprising an image file, said properties of the files being checked within a programmable logic controller (PLC) to prevent unauthorized access of a client to the web server, the method comprising:
- calculating, within the PLC, an identifier identifying a particular file of the web server comprising the image file utilizing the particular file comprising the image file;
- detecting, within the PLC, a license requirement for the particular file of the web server comprising the image file utilizing the calculated identifier;
- determining, within the PLC, an existing license for the web server within the PLC in cases of a license requirement detected for the particular file of the web server comprising the image file utilizing the calculated identifier;
- and
- preventing access to the web server associated with the PLC when a license requirement has been detected and the license for the web server associated with the PLC could not be determined.
A non-transitory computer-readable medium encoded with a computer program having program code instructions which, when executed by a programmable logic controller (PLC), causes checking of properties of files of a web server comprising an image file, said properties of the file being checked within the PLC to prevent unauthorized access of a client to the web server, the computer program comprising:
- program code for calculating, within the PLC, an identifier identifying a particular file of the web server comprising the image file utilizing the particular file comprising the image file;
- program code for detecting, within the PLC, a license requirement for the particular file of the web server comprising the image file utilizing the calculated identifier;
- program code for determining, within the PLC, an existing license for the web server within the PLC in the case of a license requirement detected for the particular file of the web server comprising the image file utilizing the calculated identifier;
- and
- program code for preventing access to the web server associated with the PLC when a license requirement has been detected and the license for the web server PLC could not be determined.
