+ </div><div class="para">
+ <code class="literal">Mono-spaced Bold</code>
+ </div><div class="para">
+ Used to highlight system input, including shell commands, file names and paths. Also used to highlight keycaps and key combinations. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ To see the contents of the file <code class="filename">my_next_bestselling_novel</code> in your current working directory, enter the <code class="command">cat my_next_bestselling_novel</code> command at the shell prompt and press <span class="keycap"><strong>Enter</strong></span> to execute the command.
+ </div></blockquote></div><div class="para">
+ The above includes a file name, a shell command and a keycap, all presented in mono-spaced bold and all distinguishable thanks to context.
+ </div><div class="para">
+ Key combinations can be distinguished from keycaps by the hyphen connecting each part of a key combination. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ Press <span class="keycap"><strong>Enter</strong></span> to execute the command.
+ </div><div class="para">
+ Press <span class="keycap"><strong>Ctrl</strong></span>+<span class="keycap"><strong>Alt</strong></span>+<span class="keycap"><strong>F1</strong></span> to switch to the first virtual terminal.

+ </div></blockquote></div><div class="para">
+ The first paragraph highlights the particular keycap to press. The second highlights two key combinations (each a set of three keycaps with each set pressed simultaneously).
+ </div><div class="para">
+ If source code is discussed, class names, methods, functions, variable names and returned values mentioned within a paragraph will be presented as above, in <code class="literal">mono-spaced bold</code>. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ File-related classes include <code class="classname">filesystem</code> for file systems, <code class="classname">file</code> for files, and <code class="classname">dir</code> for directories. Each class has its own associated set of permissions.
+ </div></blockquote></div><div class="para">
+ <span class="application"><strong>Proportional Bold</strong></span>
+ </div><div class="para">
+ This denotes words or phrases encountered on a system, including application names; dialog box text; labeled buttons; check-box and radio button labels; menu titles and sub-menu titles. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ Choose <span class="guimenu"><strong>System</strong></span> → <span class="guisubmenu"><strong>Preferences</strong></span> → <span class="guimenuitem"><strong>Mouse</strong></span> from the main menu bar to launch <span class="application"><strong>Mouse Preferences</strong></span>.

+ </div><div class="para">
+ To insert a special character into a <span class="application"><strong>gedit</strong></span> file, choose <span class="guimenu"><strong>Applications</strong></span> → <span class="guisubmenu"><strong>Accessories</strong></span> → <span class="guimenuitem"><strong>Character Map</strong></span> from the main menu bar. Next, choose <span class="guimenu"><strong>Search</strong></span> → <span class="guimenuitem"><strong>Find…</strong></span> from the <span class="application"><strong>Character Map</strong></span> menu bar, type the name of the character in the <span class="guilabel"><strong>Search</strong></span> field and click <span class="guibutton"><strong>Next</strong></span>.

+ </div></blockquote></div><div class="para">
+ The above text includes application names; system-wide menu names and items; application-specific menu names; and buttons and text found within a GUI interface, all presented in proportional bold and all distinguishable by context.
+ </div><div class="para">
+ <code class="command"><em class="replaceable"><code>Mono-spaced Bold Italic</code></em></code> or <span class="application"><strong><em class="replaceable"><code>Proportional Bold Italic</code></em></strong></span>
+ </div><div class="para">
+ Whether mono-spaced bold or proportional bold, the addition of italics indicates replaceable or variable text. Italics denotes text you do not input literally or displayed text that changes depending on circumstance. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ To connect to a remote machine using ssh, type <code class="command">ssh <em class="replaceable"><code>username</code></em>@<em class="replaceable"><code>domain.name</code></em></code> at a shell prompt.

+ </div><div class="para">
+ The <code class="command">mount -o remount <em class="replaceable"><code>file-system</code></em></code> command remounts the named file system. For example, to remount the <code class="filename">/home</code> file system, the command is <code class="command">mount -o remount /home</code>.
+ </div><div class="para">
+ To see the version of a currently installed package, use the <code class="command">rpm -q <em class="replaceable"><code>package</code></em></code> command. It will return a result as follows: <code class="command"><em class="replaceable"><code>package-version-release</code></em></code>.
+ </div></blockquote></div><div class="para">
+ Note the words in bold italics above — username, domain.name, file-system, package, version and release. Each word is a placeholder, either for text you enter when issuing a command or for text displayed by the system.
+ </div><div class="para">
+ Aside from standard usage for presenting the title of a work, italics denotes the first use of a new and important term. For example:
+ </div><div class="blockquote"><blockquote class="blockquote"><div class="para">
+ Publican is a <em class="firstterm">DocBook</em> publishing system.
+ </div></blockquote></div></div><div class="section" title="1.2. Pull-quote Conventions"><div class="titlepage"><div><div keep-together.within-column="always"><h3 class="title" id="id2839145">1.2. Pull-quote Conventions</h3></div></div></div><div class="para">

+ Because of the increased reliance on powerful, networked computers to help run businesses and keep track of our personal information, entire industries have been formed around the practice of network and computer security. Enterprises have solicited the knowledge and skills of security experts to properly audit systems and tailor solutions to fit the operating requirements of the organization. Because most organizations are increasingly dynamic in nature, with workers accessing company IT resources locally and remotely, the need for secure computing environments has become more pronounced.
+ </div><div class="para">
+ Unfortunately, most organizations (as well as individual users) regard security as an afterthought, a process that is overlooked in favor of increased power, productivity, and budgetary concerns. Proper security implementation is often enacted postmortem — <span class="emphasis"><em>after</em></span> an unauthorized intrusion has already occurred. Security experts agree that taking the correct measures prior to connecting a site to an untrusted network, such as the Internet, is an effective means of thwarting most attempts at intrusion.

+ Computer security is a general term that covers a wide area of computing and information processing. Industries that depend on computer systems and networks to conduct daily business transactions and access crucial information regard their data as an important part of their overall assets. Several terms and metrics have entered our daily business vocabulary, such as total cost of ownership (TCO) and quality of service (QoS). Using these metrics, industries can calculate aspects such as data integrity and high-availability as part of their planning and process management costs. In some industries, such as electronic commerce, the availability and trustworthiness of data can be the difference between success and failure.

+ A vulnerability assessment is an internal audit of your network and system security; the results of which indicate the confidentiality, integrity, and availability of your network (as explained in <a class="xref" href="#sect-Security_Guide-What_is_Computer_Security-Standardizing_Security" title="1.1.1.3.

+ </div><div class="para">
+ When performing an outside looking in vulnerability assessment, you are attempting to compromise your systems from the outside. Being external to your company provides you with the cracker's viewpoint. You see what a cracker sees — publicly-routable IP addresses, systems on your <em class="firstterm">DMZ</em>, external interfaces of your firewall, and more. DMZ stands for "demilitarized zone", which corresponds to a computer or small subnetwork that sits between a trusted internal network, such as a corporate private LAN, and an untrusted external network, such as the public Internet. Typically, the DMZ contains devices accessible to Internet traffic, such as Web (HTTP) servers, FTP servers, SMTP (e-mail) servers and DNS servers.
+ </div><div class="para">
+ When you perform an inside looking around vulnerability assessment, you are somewhat at an advantage since you are internal and your status is elevated to trusted. This is the viewpoint you and your co-workers have once logged on to your systems. You see print servers, file servers, databases, and other resources.
+ </div><div class="para">
+ There are striking distinctions between these two types of vulnerability assessments. Being internal to your company gives you elevated privileges more so than any outsider. Still today in most organizations, security is configured in such a manner as to keep intruders out. Very little is done to secure the internals of the organization (such as departmental firewalls, user-level access controls, authentication procedures for internal resources, and more). Typically, there are many more resources when looking around inside as most systems are internal to a company. Once you set yourself outside of the company, you immediately are given an untrusted status. The systems and resources available to you externally are usually very limited.

For this reason, the press often uses the term hacker to describe those who illicitly access systems and networks with unscrupulous, malicious, or criminal intent.

Another common error is when default passwords or keys to services are left unchanged. For example, some databases have default administration passwords because the database developers assume that the system administrator changes these passwords immediately after installation. If a database administrator fails to change this password, even an inexperienced cracker can use a widely-known default password to gain administrative privileges to the database.

+ Inherently, such services can also more easily fall prey to what the security industry terms the <em class="firstterm">man-in-the-middle</em> attack. In this type of attack, a cracker redirects network traffic by tricking a cracked name server on the network to point to his machine instead of the intended server. Once someone opens a remote session to the server, the attacker's machine acts as an invisible conduit, sitting quietly between the remote service and the unsuspecting user capturing information. In this way a cracker can gather administrative passwords and raw data without the server or the user realizing it.
+ </div><div class="para">
+ Another category of insecure services include network file systems and information services such as NFS or NIS, which are developed explicitly for LAN usage but are, unfortunately, extended to include WANs (for remote users). NFS does not, by default, have any authentication or security mechanisms configured to prevent a cracker from mounting the NFS share and accessing anything contained therein. NIS, as well, has vital information that must be known by every computer on a network, including passwords and file permissions, within a plain text ASCII or DBM (ASCII-derived) database. A cracker who gains access to this database can then access every user account on a network, including the administrator's account.

+ When updating software on a system, it is important to download the update from a trusted source. An attacker can easily rebuild a package with the same version number as the one that is supposed to fix the problem but with a different security exploit and release it on the Internet. If this happens, using security measures such as verifying files against the original RPM does not detect the exploit. Thus, it is very important to only download RPMs from trusted sources, such as from Fedora and to check the signature of the package to verify its integrity.

The less reliable approach is to query the network stack using commands such as <code class="command">netstat -an</code> or <code class="command">lsof -i</code>. This method is less reliable since these programs do not connect to the machine from the network, but rather check to see what is running on the system.

It is important to understand how this mechanism works, because a user who walks away from a terminal while <code class="filename">pam_timestamp.so</code> is in effect leaves the machine open to manipulation by anyone with physical access to the console.
+ </div><div class="para">
+ In the PAM timestamp scheme, the graphical administrative application prompts the user for the root password when it is launched. When the user has been authenticated, the <code class="filename">pam_timestamp.so</code> module creates a timestamp file.

Instead, the <code class="filename">pam_timestamp.so</code> module freshens the timestamp file, reserving an extra five minutes of unchallenged administrative access for the user.
