Nowadays, most company that has transaction process want to ensure that there are no possible failure happened. For instance, if sudden damage happened occurring at primary database, the second one will take over the responsibility of previous work automatically. This process can happen if the company systems have data replication. Data replication is a process that copies and maintains data from a database in one computer or severs to a database in another so that all users share and store same level of the information. This is also increase data availability and enhances data access relevant to their task without interfering work of others. The problem is how to make sure that connection/valuable in data replication is secure. In view of this issue, this paper proposed a secure data replication using encryption algorithm. Encryption is the process of converting readable character into another version of transformation to prevent unauthorized access. So that valuable data information will more secured and this method show a data from a database will be encrypted first then replicate it to another server. The unauthorized user also cannot sniff into database server easily. Thus, this paper approach encryption of data replication using Advanced Encryption Standard (AES) encryption is a symmetric encryption algorithm which are can encrypt and decrypt data or text. AES was created to be efficient and support block length of 128 bits and key lengths of 128, 192, and 256 bits. This is useful to ensure that sensitive data was secured
