Cisco supports two GUI-based products that allow you to configure and manage your security appliance The Adaptive Security Device Manager (ASDM) is used as an alternative to the CLI Many administrators are very familiar with GUI-based interfaces and don t feel comfortable working with the OS-style CLI For them, Cisco offers the ASDM software ASDM offers an easy-to-use web/Java-based GUI that lets you not only configure your appliance, but also manage it With ASDM, you can perform complex configuration tasks and gather important statistics 27 covers the use of the ASDM NOTE ASDM replaces the PIX Device Manager (PDM) starting in version 7 of the operating system If you are running version 6 or earlier on a PIX, then you ll need to use PDM for a GUI-based tool Cisco also offers an alternative GUI product called the Cisco Security Manager (CSM) CSM is more of a management tool than a configuration tool One problem that larger internetworks face is the management of policies, especially security policies, across a broad range of devices If you have 50 perimeter routers and 20 ASAs, ensuring that all of these security devices have the appropriate security policies applied to them can become a daunting task CSM allows you to create your security policies from a single management platform and then have these policies applied to the appropriate device or group of devices With CSM, you can create separate sets of policies based on the location and the traffic flowing through these devices CSM even supports change management tools to ensure that an extra set of eyes can view and approve the changes before they are applied to devices in your network NOTE In this sense, CSM is not a tool you d use to configure an individual security appliance, but rather a tool you d use to manage the security policies on multiple security appliances.

can have more than one canonical cover, and, further, in some cases the result of the algorithm depends on the order in which it considers the dependencies in Fc If a relation Ri is in the decomposition generated by the synthesis algorithm, then Ri is in 3NF Recall that when we test for 3NF, it suf ces to consider functional dependencies whose right-hand side is a single attribute Therefore, to see that Ri is in 3NF, you must convince yourself that any functional dependency B that holds on Ri satis es the de nition of 3NF Assume that the dependency that generated Ri in the synthesis algorithm is Now, B must be in or , since B is in Ri and generated Ri Let us consider the three possible cases: B is in both and In this case, the dependency would not have been in Fc since B would be extraneous in Thus, this case cannot hold B is in but not Consider two cases: is a superkey The second condition of 3NF is satis ed is not a superkey Then must contain some attribute not in Now, since B is in F + , it must be derivable from Fc by using the attribute closure algorithm on The derivation could not have used if it had been used, must be contained in the attribute closure of , which is not possible, since we assumed is not a superkey Now, using ( {B}) and B, we can derive B (since , and cannot contain B because B is nontrivial) This would imply that B is extraneous in the right-hand side of , which is not possible since is in the canonical cover Fc Thus, if B is in , then must be a superkey, and the second condition of 3NF must be satis ed B is in but not Since is a candidate key, the third alternative in the de nition of 3NF is satis ed Interestingly, the algorithm we described for decomposition into 3NF can be implemented in polynomial time, even though testing a given relation to see if it satis es 3NF is NP-hard.

Sales management should also ask sales personnel this very simple question: Does the sales compensation program motivate you to achieve the company s objectives Finally, examine both new hire acceptances and voluntary termination rates Determine why applicants decline offers Use a telephone
