Your user name and password should never be transmitted over a network without protection as it could be intercepted and used by someone else to impersonate you or gain access to sensitive information. Other private information such as bank account information should also be protected when transmitted across a network. If the network session was encrypted then you would not have to worry as much about the data being compromised while it is being transmitted. </div><div class="para"> Data in motion is particularly vulnerable to attackers because the attacker does not have to be near the computer in which the data is being stored rather they only have to be somewhere along the path. Encryption tunnels can protect data along the path of communications.

This is useful to maintain integrity of the message or file and also protects the confidentiality of the information contained within the file or email.

Some file based encryption solutions will leave remnants of the encrypted files that an attacker who has physical access to your computer can recover under some circumstances. To protect the contents of those files from attackers who may have access to your computer, use file based encryption combined with another solution such as full disk encryption.

Because most organizations are 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 <em class="firstterm">postmortem</em> — after an unauthorized intrusion has already occurred. Security experts agree that the right measures taken prior to connecting a site to an untrusted network, such as the Internet, is an effective means of thwarting most attempts at intrusion.

Depending on your knowledge of Linux and how comfortable you are with modifying your system, some changes could be made to help make your installation more secure. As mentioned above, the NSA has hardening guides and tips for securing Red Hat Enterprise Linux 5. Likewise, the <a href="http://www.disa.mil/">Defense Information Systems Agency</a> (DISA) has an <a href="iase.disa.mil">Information Assurance Support Environment</a> in which they publish checklists and tests for verifying the security of your system. The documents from the NSA are a good read for anyone familiar with Linux while the information from DISA is extremely specific and advanced knowledge of Unix/Linux would be a great benefit. Links to these documents are listed below. We will try to pull some of the larger items out of these documents and explain how to implement them in Fedora and why they are important. In addition to documentation, DISA has made available SR R scripts that allow an administrator to check specific settings on a system quickly. The SRR scripts will provide an XML-formatted report listing any known vulnerable settings that you have on your system. </div></div><ul class="docnav"><li class="previous"><a accesskey="p" href="chap-Security_Guide-General_Principles_of_Information_Security.html"><strong>Prev</strong>Chapter 4.

Instead of authenticating each user to each network service, Kerberos uses symmetric encryption and a trusted third party (a KDC), to authenticate users to a suite of network services.

If the software is part of a package within a Fedora distribution that is currently supported, Fedora. is committed to releasing updated packages that fix the vulnerability as soon as possible. Often, announcements about a given security exploit are accompanied with a patch (or source code that fixes the problem). This patch is then applied to the Fedora package, tested by the Red Hat quality assurance team, and released as an errata update. However, if an announcement does not include a patch, a Red Hat developer works with the maintainer of the software to fix the problem. Once the problem is fixed, the package is tested and released as an errata update. </div><div class="para"> If an errata update is released for software used on your system, it is highly recommended that you update the effected packages as soon as possible to minimize the amount of time the system is potentially vulnerable. @@ -19,9 +19,9 @@ Red Hat Network allows the majority of the update process to be automated.
