Each process is equipped with access 19 to five standard keyrings: UID-specific, GID-specific, session, 20 process and thread. 21 22 If you are unsure as to whether this is required, answer N. 23 24config KEYS_DEBUG_PROC_KEYS 25 bool "Enable the /proc/keys file by which all keys may be viewed" 26 depends on KEYS 27 help 28 This option turns on support for the /proc/keys file through which 29 all the keys on the system can be listed. 30 31 This option is a slight security risk in that it makes it possible 32 for anyone to see all the keys on the system. Normally the manager 33 pretends keys that are inaccessible to a process don't exist as far 34 as that process is concerned. 35 36config SECURITY 37 bool "Enable different security models" 38 depends on SYSFS 39 help 40 This allows you to choose different security modules to be 41 configured into your kernel. 42 43 If this option is not selected, the default Linux security 44 model will be used. 45 46 If you are unsure how to answer this question, answer N. 47 48config SECURITY_NETWORK 49 bool "Socket and Networking Security Hooks" 50 depends on SECURITY 51 help 52 This enables the socket and networking security hooks. 53 If enabled, a security module can use these hooks to 54 implement socket and networking access controls. 55 If you are unsure how to answer this question, answer N. 56 57config SECURITY_CAPABILITIES 58 tristate "Default Linux Capabilities" 59 depends on SECURITY 60 help 61 This enables the "default" Linux capabilities functionality. 62 If you are unsure how to answer this question, answer Y. 63 64config SECURITY_ROOTPLUG 65 tristate "Root Plug Support" 66 depends on USB && SECURITY 67 help 68 This is a sample LSM module that should only be used as such. 69 It prevents any programs running with egid == 0 if a specific 70 USB device is not present in the system. 71 72 See <http://www.linuxjournal.com/article.php?sid=6279> for 73 more information about this module. 74 75 If you are unsure how to answer this question, answer N. 76 77config SECURITY_SECLVL 78 tristate "BSD Secure Levels" 79 depends on SECURITY 80 select CRYPTO 81 select CRYPTO_SHA1 82 help 83 Implements BSD Secure Levels as an LSM. See 84 <file:Documentation/seclvl.txt> for instructions on how to use this 85 module. 86 87 If you are unsure how to answer this question, answer N. 88 89source security/selinux/Kconfig 90 91endmenu 92 93
