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. - - - == nmap == - - Nmap ("Network Mapper") is a free and open source (license) utility for network discovery and security auditing. - Many systems and network administrators also find it useful for tasks such as network inventory, - managing service upgrade schedules, and monitoring host or service uptime. - - usage : To start nikto simply write in the terminal : - - nmap - - More detailed usage can be found in the man pages and README file of the package.
