As security vulnerabilities generated by the developments in information and communication technologies as well as emerging technologies can lead to severe loss in terms of individual and institutional aspects, the importance of information security has been increasing in recent years. Nowadays, digital information is considered as an important asset which must be appropriately evaluated and protected against all forms of unauthorized access, use, disclosure, modification, destruction, or denial. Since information security is more prominent and more important now than ever before, this growing awareness of digital information security has led societies to develop innovative ways of protecting their sensitive information. On the other hand, in today's digital world, keeping sensitive information secure is not as easy as it was in the past. In this regard, it is obvious that for all types of institutions there is a need for security software which provides the necessary security measures and policies for the protection and retrieval of sensitive digital information. To ensure information security, security software must have the ability to make logging of certain events. Through log files, some analysis can be performed to find out what kind of attacks were done by which users and when. In this respect, this study proposes a novel approach of recording traffic flow on the log files stored on a server to determine the changes made by unauthorized people/users on the log records, and this way ensures the security of the log records and contributes to digital forensics processes in terms of accuracy, integrity and confidentiality of the log records.
