+
+         == bastille ==
+
+        Bastille  is  a  system hardening / lockdown program which enhances the
+        security of a Unix host.  It configures daemons, system settings and
+        firewalls to be more secure.  It can shut off unneeded services
+        like rcp and rlogin, and helps create "chroot jails" that help limit the
+        vulnerability of common Internet services like Web services and DNS.
+
+        usage : The functionality of Bastille which is available is
+                restricted to a purely informational one. The command:
+                bastille -c --os Yocto
+                will cause a series of menus containing security questions
+                about the system to be displayed to the user. For each
+                question, a default response, specified in the configuration
+                file which is installed with Bastille, will be selected.
+                The user may select an alternate response. When the user
+                has completed the sequence of menus Bastille saves the
+                responses to the configuration file.
+
+                The command:
+                bastille -l lists the configuration files that Bastille
+                is able to locate.
+
+                The other functionality which Bastille is intended to provide
+                is actually unavailable. This is not due to errors in poky
+                installation or configuration of the application. The Bastille
+                distribution is no longer supported. Significant modifications
+                would be required to make it possible to make use of the
+                functionality which is currently unavailable.
+
+
+        Additional information about Bastille can be found in the package
+        README file and other documentation.
+
+        Alternatives to Bastille include buck-security and checksecurity,
+        described elsewhere in this file.
+
+
+        == redhat-security ==
+
+        Sometimes you want to check different aspects of a distribution for security problems.
+        This can be anything from file permissions to correctness of code. This is a collection of those tools.
+        Depending on what information the tool has to access, it may need to be run as root.
+
+        - rpm-chksec.sh : This will take an rpm name as input and verify each ELF file to see if its compiled with the intended flags
+                          to most effectively use PIE and RELRO. Green is good, Orange could use work but is acceptable, and Red needs fixing.
+                          It has a mode --all that is the equivalent of using rpm -qa and feeding the packages to it.
+                          In this mode it will only give a summary result for the package. To find which files don't comply,
+                          re-run using just the package name.
+
+		!!! WARNING !!! - in order to use this script you need to add to your conf/local.conf file the following lines:
+						IMAGE_ROOTFS_EXTRA_SPACE = ""  - specifying the extra space of the image
+						IMAGE_FEATURES += "package management" - for the correct output of rpm -qa
+
+        - find-nodrop-groups.sh : This will scan a whole file system to see if a program makes calls to change UID
+                                  and GID without also calling setgroups or initgroups.
+
+        - rpm-drop-groups.sh : Same as above, but takes an rpm name instead.
+
+        - find-chroot.sh : This script scans the whole file system looking for ELF files that calls chroot(2) that also do not include a call to chdir.
+                           Programs that fail to do this do not have the cwd inside the chroot. This means the app can escape the protection that was intended.
+
+        - find-chroot-py.sh : This test is like the one above except it examines python scripts for the same problem.
+
+        - find-execstack.sh : This program scans the whole file system for ELF programs that have marked the stack as being executable.
+                              This means that if the program has another vulnerablity such as stack buffer overflow,
+                              any code the attacker places there is executable. Any program found must be fixed.
+
+        - find-hidden-exec.sh : This program scans the whole file system looking for excutables that are hidden.
+                                Anything found must be investigated since its highly unusual for executables to be hidden.
+
+        - find-sh4errors.sh : This program scans the whole file system looking for shell scripts.
+                              It then does a sh -n on the script which causes bash to parse the file to see if there are any mistakes.
+
+        - selinux-check-devices.sh : This script checks the /dev directory to see if there are any devices that are not correctly labeled.
+                                     Anything found by this test should be reported so that selinux policy can be fixed.
+                                     This test is very hardware specific, so to be effective a lot of people with different hardware
+                                     should run this test each upstream kernel version release.
+
+        - selinux-ls-unconfined.sh :  This script scans the running processes and looks for anything labeled with initrc_t or inetd.
+                                      These both mean that there are daemons that do not have policy and are therefore running unconfined.
+                                      These should be reported as SE Linux policy problems. Because it checks currently running daemons,
+                                      the more you have running, the better the test is.
+
+        - find-sh4tmp.sh : This script scans the whole filesystem to check if shell scripts are using well known tmp file names
+                           instead of obscure ones created by something like mktemp.
+
+        - find-elf4tmp.sh : This script scans the whole file system for ELF files using /tmp. When it finds this,
+                            it also looks to see if any of the known good random name generator functions is called by looking
+                            at the symbol table. If not, it will output the string.
+
+        - lib-bin-check.sh : This will check all installed library packages to see if an application is also part of the package.
+                             The relationship to security is that the SHA256 hash check will fail if a 32 bit version overwrites it.
+                             Also, the less binaries on a system, the more secure it is by virtue of removing the chance for an exploitable bug.
+
+
+                usage : simply invoke the script name in the terminal.
+
+
+        == pax-utils ==
+
+		( This package can be found in oe-core )
+
+        pax-utils is a small set of various PaX aware and related utilities for
+        ELF binaries.
+
+        - scanelf : With this application you can print out information specific to the ELF structure of a binary.
+                    For more help please consult the man pages or the readme file.
+
+        - pspax : is a user-space utility that scans the proc directory and list
+                  ELF types, as well as their respective PaX flags and filenames and
+                  attributes. Depending on build options, it may additionaly display the
+                  process running set of capabilities.
+
+        - scanmacho : is a user-space utility to quickly scan given
+                      Mach-Os, directories, or common system paths for different information. This
+                      may include Mach-O types, their install_names, etc.
+
+        - dumpelf : is a user-space utility to dump all of the internal
+                    ELF structures into the equivalent C structures for fun debugging and/or
+                    reference purposes.
+
+
+                usage : simply invoke the script name in the terminal.
+
+
+        == buck-security ==
+
+        Buck-Security is a security scanner for Debian and Ubuntu Linux. It runs a couple of important checks and helps you to harden your Linux
+        system. This enables you to quickly overview the security status of your Linux system.
+
+                usage :	!!! before starting to use this tool please run the following command: !!!
+
+						export GPG_TTY=`tty`
+
+						This command is needed for the usage of the comand --make-checksum, which creates
+						a checksum for the files in the system.
+
+						switch to directory /usr/local/buck-security.
+                        before running the script, you should check the activated checks in conf/buck-security.conf file.
+                        after altering the changes, save the file and simply run :
+
+                        ./buck-security
+
+                        you can choose between different outputs : 1, 2(default) or 3.
+
+                        More detailed usage can be found typing ./buck-security --help
+
+
+        == libseccomp ==
+
+        The libseccomp library provides and easy to use, platform independent, interface to the Linux Kernel's syscall filtering mechanism: seccomp.
+        The libseccomp API is designed to abstract away the underlying BPF based syscall filter language and present a more conventional
+        function-call based filtering interface that should be familiar to, and easily adopted by application developers.
+
+                usage : More detailed usage can be found in the man pages and README file of the package.
+
+
+
+        == checksecurity ==
+
+        checksecurity is a simple package which will scan your system for several simple security holes.
+        It uses a simple collection of plugins, all of which are shell scripts which are configured by environmental variables.
+
+
+                usage : To start checksecurity simply write in the terminal :
+
+                        checksecurity
+
+        More detailed usage can be found in the man pages and README file of the package.
+
+
+        == nikto ==
+
+        Nikto is an Open Source (GPL) web server scanner which performs comprehensive tests against web servers for multiple items,
+        including over 6500 potentially dangerous files/CGIs, checks for outdated versions of over 1250 servers, and version specific
+        problems on over 270 servers. It also checks for server configuration items such as the presence of multiple index files,
+        HTTP server options, and will attempt to identify installed web servers and software.
+
+                usage : To start nikto simply write in the terminal :
+
+                        nikto
+
+        More detailed usage can be found in the man pages and README file of the package.
