Network configuration remains time-consuming and error-prone with the current configuration command system. To create access control lists (ACLs) with commands containing many options is still considered as a difficult task. In light of this, we aim to develop a comprehensible way to the ACL construction. Based on Eliza, a prototype of Artificial Intelligence, we propose a new design called EasyACL that synthesizes ACL rules automatically from natural language descriptions. EasyACL demonstrates the effectiveness of domain-specific program synthesis. Through the use of natural language ACL rules can be constructed without using an excessive number of options or rigid syntax. By introducing the batch processing, we make it possible for users to apply configurations to a range of IP addresses rather than tediously repeating commands. EasyACL supports multi-platform by an intermediate representation which may be ported to the commands for both Cisco and Juniper devices. The comprehensible commands are friendly for encapsulation as well as reuse. EasyACL enables end-users with no prior programming experience to construct ACL in a natural way which lowers the bar for security management training and also reduces the errors in network administration.
