config KEYS
bool "Enable access key retention support"
help
This option provides support for retaining authentication tokens and
access keys in the kernel.
It also includes provision of methods by which such keys might be
associated with a process so that network filesystems, encryption
support and the like can find them.
Furthermore, a special type of key is available that acts as keyring:
a searchable sequence of keys. Each process is equipped with access
to five standard keyrings: UID-specific, GID-specific, session,
process and thread.
If you are unsure as to whether this is required, answer N.
config KEYS_DEBUG_PROC_KEYS
bool "Enable the /proc/keys file by which all keys may be viewed"
depends on KEYS
help
This option turns on support for the /proc/keys file through which
all the keys on the system can be listed.
This option is a slight security risk in that it makes it possible
for anyone to see all the keys on the system. Normally the manager
pretends keys that are inaccessible to a process don't exist as far
as that process is concerned.
config SECURITY
bool "Enable different security models"
depends on SYSFS
help
This allows you to choose different security modules to be
configured into your kernel.
If this option is not selected, the default Linux security
model will be used.
If you are unsure how to answer this question, answer N.
config SECURITY_NETWORK
bool "Socket and Networking Security Hooks"
depends on SECURITY
help
This enables the socket and networking security hooks.
If enabled, a security module can use these hooks to
implement socket and networking access controls.
If you are unsure how to answer this question, answer N.
config SECURITY_NETWORK_XFRM
bool "XFRM (IPSec) Networking Security Hooks"
depends on XFRM && SECURITY_NETWORK
help
This enables the XFRM (IPSec) networking security hooks.
If enabled, a security module can use these hooks to
implement per-packet access controls based on labels
derived from IPSec policy. Non-IPSec communications are
designated as unlabelled, and only sockets authorized
to communicate unlabelled data can send without using
IPSec.
If you are unsure how to answer this question, answer N.
config SECURITY_CAPABILITIES
tristate "Default Linux Capabilities"
depends on SECURITY
help
This enables the "default" Linux capabilities functionality.
If you are unsure how to answer this question, answer Y.
config SECURITY_ROOTPLUG
tristate "Root Plug Support"
depends on USB && SECURITY
help
This is a sample LSM module that should only be used as such.
It prevents any programs running with egid == 0 if a specific
USB device is not present in the system.
See <http://www.linuxjournal.com/article.php?sid=6279> for
more information about this module.
If you are unsure how to answer this question, answer N.
config SECURITY_SECLVL
tristate "BSD Secure Levels"
depends on SECURITY
select CRYPTO
select CRYPTO_SHA1
help
Implements BSD Secure Levels as an LSM. See
<file:Documentation/seclvl.txt> for instructions on how to use this
module.
If you are unsure how to answer this question, answer N.
