We introduced the concept of functional dependencies, and showed how to reason with functional dependencies We laid special emphasis on what dependencies are logically implied by a set of dependencies We also de ned the notion of a canonical cover, which is a minimal set of functional dependencies equivalent to a given set of functional dependencies We introduced the concept of decomposition, and showed that decompositions must be lossless-join decompositions, and should preferably be dependency preserving If the decomposition is dependency preserving, given a database update, all functional dependencies can be veri able from individual relations, without computing a join of relations in the decomposition We then presented Boyce Codd Normal Form (BCNF); relations in BCNF are free from the pitfalls outlined earlier We outlined an algorithm for decomposing relations into BCNF There are relations for which there is no dependencypreserving BCNF decomposition We used the canonical covers to decompose a relation into 3NF, which is a small relaxation of the BCNF condition Relations in 3NF may have some redundancy, but there is always a dependency-preserving decomposition into 3NF We presented the notion of multivalued dependencies, which specify constraints that cannot be speci ed with functional dependencies alone We de ned fourth normal form (4NF) with multivalued dependencies Section C11 of the appendix gives details on reasoning about multivalued dependencies Other normal forms, such as PJNF and DKNF, eliminate more subtle forms of redundancy However, these are hard to work with and are rarely used Appendix C gives details on these normal forms In reviewing the issues in this chapter, note that the reason we could de ne rigorous approaches to relational-database design is that the relational data model rests on a rm mathematical foundation That is one of the primary advantages of the relational model compared with the other data models that we have studied.

The usage-keys parameter generates two sets of keys, while the general-keys parameter generates one key pair; the default is general-keys if you omit it, which is what you need for certificate purposes Use usage-keys if you need two identity certificates from the same CA, which is uncommon If you don t specify a label for the key pair, it defaults to Default-RSA-Key If you don t specify a modulus (the size of the keys, in bits), it defaults to 1024: other valid sizes include 512, 768, and 2048 The noconfirm parameter, when configured, will execute the command without any interaction on your part the default is to prompt you for verification Use the show crypto key mypub key command to view the public keys on your appliance TIP You might want more than one RSA key pair SSH uses the default key pair label; but you might want to use a different key pair (with a different modulus) for certificates Here s an example of generating an RSA key pair:

ciscoasa(config)# crypto key generate rsa label mykeys INFO: The name for the keys will be: mykeys Keypair generation process ciscoasa(config)#

Closure of attribute sets Decomposition Lossless-join decomposition Legal relations Dependency preservation

In this example, a key pair label of mykeys is used to name the key pair NOTE If the RSA key pair already exists, you are prompted to overwrite the existing key pair Also, to delete an RSA key pair, use the crypto key zeroize rsa [label key_pair_label]

Intrusion prevention system (IPS) If you have the AIP-SSM card installed in an ASA, you can define policies to copy packets to or to redirect packets into the AIP-SSM card to look for and prevent attacks Anti-X If you have the CSC-SSM card installed in an ASA, you can define policies to have traffic redirected through the card to look for viruses, malware, spyware, phishing, and other types of issues with web, FTP, and e-mail applications
