Abstract
Analyzing computer code using a tree is described. For example, a client device generates a data request for retrieving data from a non-trusted entity via a network. A gateway is communicatively coupled to the client device and to the network. The gateway is configured to receive computer code from the non-trusted entity via the network. The gateway builds a tree representing the computer code. The tree has one or more nodes. A node of the tree represents a statement from the computer code. The gateway analyzes the statement to identify symbol data. The symbol data describes a name of the variable and the value of the variable. The gateway stores the symbol data in a symbol table.
