Figure 4-16. With man, you can get extensive information about most commands available on your server. Man pages can be extremely comprehensive. For a simple command like passwd, you ll be presented with 158 lines (about 3 pages of printed text). Some of the biggest man entries can fill up an entire book. The man page for the oft-used bash shell, for example, totals 5268 lines (or about a hundred printed pages). Because man pages can be so extensive, you probably won t read them in their entirety. Fortunately, it s easy to glean information from the man pages. If you know what you re looking for, you can use /string to locate the information by keyword. Imagine, for example, that you re in the man page of the bash shell and you want to know how to set a search path. Just use the command /path from within the man page, and it will instantly take you to the first instance of the word. Want to search again using the same string Press n and man shows you the next occurrence.

example, if you wish to display a certain button only on the first of the month, then use a condition. But if you want to restrict access to that button to certain users, you should use an authorization scheme. Don t fall into the trap of enforcing security through conditions, because then you might discover that your security is really an illusion. Review the section Protecting Your Resources if you have any doubts as to when to use conditions versus authorization schemes.

in the info system. Thus, the number of commands is rather limited. If you ever want to learn more about the system, use the command info info to call up more information on its usage.

he previous chapter dealt with using conditional display and authorization schemes to control which data users can access and modify. However, even when you use both of these methods, users may still be able to gain access to data that they should not be able to view, or even worse, be able to modify and delete that data. This chapter covers other ways, such as using Session State Protection (SSP), that you can help to secure your application against potential misuse by a user (either intentionally or unintentionally). We will also cover using database features, such as Virtual Private Database (VPD), which is also sometimes referred to as Fine-Grained Access Control (FGAC). Features such as VPD enable you to apply access controls at the database level, rather than at the application level.

There is one thing you should be aware of when working with man. If you use it to get information about the usage of the command passwd, it starts looking in the first section of the man pages (the section that describes normal commands). When it finds something, it displays it, and stops searching. Some items, however, appear in more than one section. Besides the command passwd, which is described in section one, there is also the configuration file /etc/ passwd, outlined in section five. If you want to be sure that man displays all existing entries on the item you re looking for, use man a. The option a tells man to keep searching and to only stop after it s scanned every section. If you know beforehand which section holds a certain item, you can tell man to look in that section by specifying the section number thus, typing man -5 passwd will only show you the man page for /etc/passwd.

Typically, you will rarely need to construct URL syntax yourself, since APEX makes it easy to link to other pages and pass session information without you needing to manually construct a URL. However, being aware of exactly how a URL is constructed will enable you to see how it could be possible for people to manipulate the URL to modify data or to access a part of your application that they shouldn t be able to access.
