* adds a C-based security policy translation tool to Xen (secpol_xml2bin) and removes the current Java security policy translator (Java dependencies). The C-based tool integrates into the Xen source tree build and install (using gnome libxml2 for XML parsing). See install.txt. * introduces security labels and related tools. Users can now use semantic-rich label names to put security-tags on domains. See example.txt, policy.txt. * moves the security configuration (currently ACM_USE_SECURITY_POLICY) from xen/Rules.mk into a separate top-level Security.mk file (it is needed by the tools/security and xen/acm). Both xen/acm and tools/security are built during the Xen build process only if ACM_USE_SECURITY_POLICY is not ACM_NULL_POLICY (which is the default setting).

INSTALLING A SECURITY POLICY IN XEN
|
|
===================================
|
|
|
|
By default, the access control architecture is disabled in Xen. To
|
|
enable the access control architecture in Xen follow the steps below.
|
|
This description assumes that you want to install the Chinese Wall and
|
|
Simple Type Enforcement policy. Some file names need to be replaced
|
|
below to activate the Chinese Wall OR the Type Enforcement policy
|
|
exclusively (chwall_ste --> {chwall, ste}).
|
|
|
|
1. enable access control in Xen
|
|
# cd "xen_root"
|
|
# edit/xemacs/vi Config.mk
|
|
|
|
change the line:
|
|
ACM_USE_SECURITY_POLICY ?= ACM_NULL_POLICY
|
|
|
|
to:
|
|
ACM_USE_SECURITY_POLICY ?= ACM_CHINESE_WALL_AND_SIMPLE_TYPE_ENFORCEMENT_POLICY
|
|
|
|
# make all
|
|
# ./install.sh
|
|
|
|
2. compile the policy from xml to a binary format that can be loaded
|
|
into the hypervisor for enforcement
|
|
# cd tools/security
|
|
# make
|
|
|
|
manual steps (alternative to make boot_install):
|
|
#./secpol_xml2bin chwall_ste
|
|
#cp policies/chwall_ste/chwall_ste.bin /boot
|
|
#edit /boot/grub/grub.conf
|
|
add the follwoing line to your xen boot entry:
|
|
"module chwall_ste.bin"
|
|
|
|
alternatively, you can try our automatic translation and
|
|
installation of the policy:
|
|
# make boot_install
|
|
|
|
[we try hard to do the right thing to the right boot entry but
|
|
please verify boot entry in /boot/grub/grub.conf afterwards;
|
|
your xen boot entry should have an additional module line
|
|
specifying a chwall_ste.bin file with the correct directory
|
|
(e.g. "/" or "/boot").]
|
|
|
|
|
|
3. reboot into the newly compiled hypervisor
|
|
|
|
after boot
|
|
#xm dmesg should show an entry about the policy being loaded
|
|
during the boot process
|
|
|
|
#tools/security/secpol_tool getpolicy
|
|
should print the new chwall_ste binary policy representation
|
|
