If you need to validate a specific patch or package version, you can view installed packages and patches via the following commands: Solaris showrev -p will list the patches that have been applied; these can be cross-referenced with the patches listed in the security advisory from Sun Linux rpm -q -a (Red Hat or other distributions using RPM) or dpkg --list (Debian and related distributions) will show the versions of installed packages Note that software can be installed outside the package-management system provided by the vendor, in which case these commands won t show you the requisite information If you need to find the version of an executable, try running the command with the -v switch In most cases, this will show you version information that you can compare with information in vulnerability notices A network scan of existing vulnerabilities also can be used to help validate the effectiveness of the patching process See the next step for further details Consider the configuration of the services, not just whether they are allowed The proper configuration of certain services such as Network File System (NFS), anonymous File Transfer Protocol (FTP), and those that allow trusted access and root login are discussed later in this chapter Space restrictions prevent us from detailing the proper configuration of every potential service (plus new vulnerabilities are discovered all the time) This is why the use of a network scanning tool is a critical component of an effective audit Such a tool will keep up with and test for the latest vulnerabilities for you

This will provide a snapshot of the current security level of the system (from a network services standpoint) The world of network vulnerabilities is an ever-changing one, and it is unrealistic to create a static audit program that will provide an up-to-date portrait of vulnerabilities that should be checked Therefore, a scanning tool that is updated frequently is the most realistic mechanism for understanding the current security state of the machine In addition, if the system administrator has a security-patching process in place, this scan will provide validation as to the effectiveness of that process (or as to whether it is really being executed)

See the Tools and Technology section later in this chapter for information on potential network vulnerability-scanning tools Even though many of these tools are designed to be nondisruptive and do not require access to the system, you should always inform the appropriate IT personnel (such as the system administrator, the network team, and IT security) that you plan to run the tool, and then get their approval and schedule with them a time to execute the tool Scanning tools can interact in an unexpected fashion with a port and cause a disruption, so it is important that others be aware of your ac-

tivities These tools should usually be run in a safe (nondisruptive) mode such that they do not attempt to exploit any vulnerabilities discovered On rare occasions, you will want to run an actual exploit to get more accurate results, but this should be done only with buy-in from and coordination with the system owner and administrator

Trusted access allows users to access the system remotely without the use of a password Specifically, the /etc/hostsequiv file creates trust relationships with specific machines, whereas the rhosts file creates trust relationships with specific users on specific machines For example, if system Trusting has an /etc/hostsequiv file that lists machine Trusted as a trusted host, then any user with an account using the same username on both systems will be able to access Trusting (the trusting machine) from Trusted (the trusted machine) without the use of a password Thus, if the username Hal exists on both machines, the owner of the Hal account on Trusted will be able to access the Hal account on Trusting without using a password Keep in mind that the key is the account name If John Jones has an account on both machines, but one has the account name jjones and the other has the account name jjonzz, then the trust relationship won t work The operating system won t acknowledge them as the same account The rhosts files work similarly except that they are specific to a user Each user can have a rhosts file in his or her home directory that provides trusted access to his or her account If username Barry on system Trusting has a rhosts file in his home directory and that rhosts file lists system Trusted, then the Barry account on Trusted will be able to access the Barry account on Trusting without using a password Alternatively, system and username pairs can be listed in the rhosts file The rhosts file for Barry on Trusting could list username Wally on system Trusted This would mean that the Wally account on Trusted would be able to access the Barry account on Trusting without using a password If the system you are auditing has trust relationships with other machines, the security of the trusting system depends on the security of the trusted system If the accounts that are trusted are compromised, then, by definition, the accounts on the system you are auditing will be compromised as well This is the case because access to the trusted machine provides access to the trusting machine It is best to avoid this sort of dependency if at all possible NOTE If NIS is used, it is also possible to grant trusted access to specific netgroups (groups of usernames)
