NAME¶
sedta - Domain transition analysis for SELinux policies
SYNOPSIS¶
sedta [OPTIONS] -s SOURCE [-t TARGET (-S|-A LIMIT)] [EXCLUDE [EXCLUDE
...]]
DESCRIPTION¶
sedta is a command line tool that allows the user to perform domain
transition analyses on an SELinux policy.
POLICY¶
sedta supports loading SELinux policies in one of two formats.
- source:
- A single text file containing a monolithic policy source. This file is
usually named policy.conf.
- binary:
- A single file containing a binary policy. This file is usually named by
version on Linux systems, for example, policy.30. This file is
usually named sepolicy on Android systems.
If no policy file is provided, sedta will search for the
policy running on the current system. If no policy can be found,
sedta will print an error message and exit.
OPTIONS¶
Analysis Settings¶
- -p POLICY
- Specify the policy to analyze. If none is specified, sedta will
search for the policy running on the current system.
- -s SOURCE
- Specify the source type to use in the domain transition analysis.
- -t TARGET
- Specify the target type to use in the domain transition analysis. Using
this option will also require specifying an analysis algorithm.
Analysis Algorithms¶
sedta uses graph algorithms to analyze the domain transition paths of an
SELinux policy. The following algorithms are options for determining paths
from a source type to a target type.
- -S
- Print the shortest domain transition path(s) from the source type to the
target type. If multiple paths have the same length, all will be
displayed.
- -A LIMIT
- Print all domain transition path(s) up to LIMIT steps long. Depending on
the connectiveness of the policy, this may be extremely expensive.
Analysis Options¶
- -r
- Perform a reverse domain transition analysis. The domain transitions will
be analyzed to find the the parent domains, instead of finding the child
domains.
- -l LIMIT_TRANS
- Specify the maximum number of domain transitions to output. The default is
unlimited.
- EXCLUDE
- A space-separated list of types to exclude from the analysis.
General Options¶
- --stats
- Print domain transition graph statistics at the end of the analysis.
- -h, --help
- Print help information and exit.
- --version
- Print version information and exit.
- -v, --verbose
- Print additional informational messages.
- --debug
- Enable debugging output.
