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 help 39 This allows you to choose different security modules to be 40 configured into your kernel. 41 42 If this option is not selected, the default Linux security 43 model will be used. 44 45 If you are unsure how to answer this question, answer N. 46 47config SECURITY_NETWORK 48 bool "Socket and Networking Security Hooks" 49 depends on SECURITY 50 help 51 This enables the socket and networking security hooks. 52 If enabled, a security module can use these hooks to 53 implement socket and networking access controls. 54 If you are unsure how to answer this question, answer N. 55 56config SECURITY_CAPABILITIES 57 tristate "Default Linux Capabilities" 58 depends on SECURITY 59 help 60 This enables the "default" Linux capabilities functionality. 61 If you are unsure how to answer this question, answer Y. 62 63config SECURITY_ROOTPLUG 64 tristate "Root Plug Support" 65 depends on USB && SECURITY 66 help 67 This is a sample LSM module that should only be used as such. 68 It prevents any programs running with egid == 0 if a specific 69 USB device is not present in the system. 70 71 See <http://www.linuxjournal.com/article.php?sid=6279> for 72 more information about this module. 73 74 If you are unsure how to answer this question, answer N. 75 76config SECURITY_SECLVL 77 tristate "BSD Secure Levels" 78 depends on SECURITY 79 select CRYPTO 80 select CRYPTO_SHA1 81 help 82 Implements BSD Secure Levels as an LSM. See 83 <file:Documentation/seclvl.txt> for instructions on how to use this 84 module. 85 86 If you are unsure how to answer this question, answer N. 87 88source security/selinux/Kconfig 89 90endmenu 91 92
