Many users access their information such as civil or military services and projects in an electronic way, saving both their common data as well as sensitive or personal information remotely make hundreds of attack jeopardize these information in an unauthorized way. Continuously, the attackers are working on improving developed and invisible techniques for targeting the victim, and they are taking all the methods and attempts to penetrate the network in a way that is not detected by eliminating the traces of attacks such as system log files and information related to the victim system so as not to be targeted. This paper proposed immutable and secure log files from unauthenticated access by using the blockchain technique. It will assist to provide proof of log manipulation and nonrepudiation. The results have been tested using two cases attacking the server with a blockchain and without a blockchain, the first case the log file is not altered because the attacker do not know the correct series of hash value he enters a random hash value so he is detected, second case the log file is manipulated by the attacker without being detected.
