3	bool "Integrity subsystem"
4	depends on SECURITY
5	default y
6	help
7	  This option enables the integrity subsystem, which is comprised
8	  of a number of different components including the Integrity
9	  Measurement Architecture (IMA), Extended Verification Module
10	  (EVM), IMA-appraisal extension, digital signature verification
11	  extension and audit measurement log support.
12
13	  Each of these components can be enabled/disabled separately.
14	  Refer to the individual components for additional details.

19	bool "Digital signature verification using multiple keyrings"
20	depends on KEYS
21	default n
22	select SIGNATURE
23	help
24	  This option enables digital signature verification support
25	  using multiple keyrings. It defines separate keyrings for each
26	  of the different use cases - evm, ima, and modules.
27	  Different keyrings improves search performance, but also allow
28	  to "lock" certain keyring to prevent adding new keys.
29	  This is useful for evm and module keyrings, when keys are
30	  usually only added from initramfs.

40	help
41	  This option enables digital signature verification using
42	  asymmetric keys.

44config INTEGRITY_AUDIT
45	bool "Enables integrity auditing support "
46	depends on AUDIT
47	default y
48	help
49	  In addition to enabling integrity auditing support, this
50	  option adds a kernel parameter 'integrity_audit', which
51	  controls the level of integrity auditing messages.
52	  0 - basic integrity auditing messages (default)
53	  1 - additional integrity auditing messages
54
55	  Additional informational integrity auditing messages would
56	  be enabled by specifying 'integrity_audit=1' on the kernel
57	  command line.
