<li><p>Limiting the number of authentication attempts for a given Jabber ID in a given time period. While such a limit may seem beneficial, in fact it might result in locking out the legitimate owner of a Jabber ID if a malicious entity attempts a large number of illegitimate authentication attempts for the Jabber ID; therefore such a limit is not recommended and it is instead recommended to limit the number of connections and connection attempts on a per-IP basis.</p></li> <li><p>Limiting the number of authentication attempts for a given Jabber ID in a given time period.

<li><p>Limiting the number of XMPP resource identifiers allowed to an account at any one time. This may help to prevent a rogue account from creating an unlimited number of sessions and therefore exhausting the resources of the server's session manager.</p></li> <li><p>Limiting the number of XMPP resource identifiers allowed to an account at any one time.

<li><p>Limiting the absolute size in bytes of XML stanzas accepted by the server, or of particular aspects of an XML stanza (e.g., attribute values, element names, XML character data). Limits on particular aspects of an XML stanza are probably not needed, as long as it is possible to limit the absolute size of each XML stanza, since such a limit may help to prevent exhaustion of server resources (e.g., XML parser processing capacity).</p></li> <li><p>Limiting the absolute size in bytes of XML stanzas accepted by the server, or of particular aspects of an XML stanza (e.g., attribute values, element names, XML character data).
