In practice, an email is cheeked by a program if containing spam or virus before sent to its destination. By using an existing anti-spam or email anti-virus technology, it is possible to prevent an unauthorized person in an organization to send an email consisting of confidential documents. This technique provides a mean of changing the technology that is normally filtering spam and virus from outside of local area network to become a tool to secure confidential document by filtering outgoing emails. Confidential documents must be prevented from leaking outside an organization’s premises. Despite various ways to move a document to a different location, email is still one of the main alternatives to communication between parties and used to send documents as attachments. The solution consists of three parts which are a sample architecture, a delivery approval mechanism, and an email filtering agent. The network architecture centers on the placement of email filtering agent to focus on cheeking outgoing emails. The delivery approval mechanism uses the concept of multilevel security to ensure document confidentiality while providing system availability when required. The email filtering agent is a result of expanding a program called Amavis so that it is capable to do document classification and filtering as extra features. Some testing scenarios are carried out to validate the functionality of the agent inside the architecture. The results show that the proposed solution can secure confidential documents while handling normal email delivery.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Document Classification,Document filtering,Document security,E-mail delivery,Email filtering,Multi-level security,New approaches,System availability[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text]Document classifier,Document filtering,Document security,Email filtering,Network architecture[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.1109/IWBIS.2018.8471696[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
