The attribute axis is used to select the attribute nodes associated with an element node. 
If the context node is an element node, the location paths 

attribute::* or @* 

will each return all the attribute nodes associated with that element node. 

To select a specific attribute node named security, you write either 

attribute::security 

or 

@security 

@ is an abbreviation for the attribute axis.
If the context node is not an element node, the attribute axis returns an empty node-set.
