As noted earlier, another limitation of traditional access lists is that they are incapable of detecting whether a packet is truly part of an existing upper-layer conversation Normally the access list examines each packet as a stand-alone entity As mentioned above, traditional access lists do provide a mechanism for checking individual packets to determine if it is part of an existing conversation through the use of the established keyword However, this check is easily spoofed by a skilled attacker and will only deter the most casual offenders Additionally, the established keyword check is only useful for the TCP protocol and is unavailable for UDP conversations

Another limitation of traditional access lists is their limited capability to examine information above the IP layer Extended access lists have the capability to look at certain information in the layer 4 headers, but only in a very simplistic sense Traditional access lists have no way of examining information above layer 4 and are incapable of securely handling protocols that use unpredictable layer 4 information, such as FTP Both of these limitations are addressed by next-generation access lists We will examine the new access list enhancements developed by Cisco in 8

errors, although not the only ones, are: Failure to create access list entries in the correct order Failure to apply the access list to an interface in the correct direction Failure to apply the access list to an interface Failure to add new access list entries in the correct order It is important that you be aware of these potential pitfalls as you develop a greater understanding of Cisco access lists In the next section, we discuss a few key principles to keep in mind when configuring Cisco access lists

We will conclude this section by examining the key details that are important to remember when configuring Cisco access lists Top-down processing Cisco access lists are evaluated in a sequential fashion beginning with the first entry As soon as a match is encountered, the access list processing is completed and no more entries are considered Therefore, it is important to put more specific entries toward the top of the access list Implicit deny all There is always an implicit "deny all" entry at the end of the access list Thus, any packet that does not explicitly match one of the access list entries will automatically be denied This behavior can be overridden by placing an explicit "permit all" as the last entry in the list New entries are added to the bottom Any new access list entries are automatically added to the bottom of the list This fact is important to remember when attempting to make modifications to an existing access list If modifications are necessary for an entry in an access list, it may be necessary to delete and recreate the entire access list This process can be mediated by creating the access list off-line in a text file and using TFTP to upload any changes to existing access lists Separate creation and application processes The actual application of an access list is done on an interface or subinterface basis The creation of an access list is done before an the list is applied to an interface Access lists reside in the configuration file and not be applied to any interface Similarly, an access list that has not been defined can be applied to an interface (see next paragraph) Undefined access lists If an access list that has not been created is referenced in the configuration, the effect will be the same as if the access list contained a "permit all" entry In other words, all traffic will be permitted We have found this principle does not always hold true, however We strongly recommend that you never apply an access list to an interface unless the access list has been created We also recommend removing the access list from the interface before making any changes to the access list
