Minimizing Enumeration Requests
Enumeration requests are directory queries that request all of a database, for example all users or all groups. Enumeration requests of large databases could reduce network and server performance. For this reason, you may want to restrict the use of commands and applications that enumerate.
The following commands generate enumeration requests:
•finger(1)
•grget(1) with no options
•pwget(1) with no options
•groups(1)
•listusers(1)
•logins(1M)
•All netgroup calls
In addition, applications written with routines of families such as the getpwent, getgrent, gethostent, and getnetent family of calls can enumerate a map, depending on how they are written.
