From: Juraj Hlista <juro.hlista(a)gmail.com> Reactions are identified by numbers in the kernel, but user space requires string identifiers of reactions. That's why there must be some mapping from numbers to strings and vice versa. This is implemented using SQLite. A table where the reaction strings and numbers are kept has the following columns: number, string, used. 'number' is the value used in the kernel, 'string' is used in the user space. 'used' means how many times is the reaction used in audit rules. When a new reactive rule is added, the database determines what number will be sent to the kernel for each reaction: 1 if the table is empty if string is already in the table, its number will be sent to the kernel and 'used' incremented if there isn't such a string in the table, but there is some row with 'used' == 0, then string in this row will be rewritten by the new one and 'used' set to 1 otherwise max(number) + 1 will be used When a reactive rule is removed, 'used' is just decremented. More reactions per one rule are supported, they are defined by react field (-F react=reaction). This patch includes only mapping, audit plugin for triggering reactions is being developed.

Auditing in old versions of Linux

by Mario Chancay

Due to technical and budget constrains, we are not yet able to migrate some old linux boxes to the latest versions but need to configure auditing under the following platforms : - Red Hat Linux Enterprise AS 3.4, 3.5, 3.6 - Red Hat Linux 4.x Need advice to confirm if auditing is possible under this versions and also the recommended procedure to install/setup as I understand that the auditd package depends on the kernel version. Regards Mario

RE: Auditing in old versions of Linux

by Woodie, Paul E, CIV, DSS

There is an audit package called Snare, which would make possible auditing on previous versions of linux. It worked well. Unfortunately, that also required (usually) modified versions of the kernel. Perhaps you can find some of those components. I have not used Snare in quite a while.

a new tool about audit data visualization

by liequan che

Dear all: I have written a new audit log visualization tool named aureport-gui based on pychart and pyqt. you can download the source packages at http://code.google.com/p/aureport-gui/downloads/list.or use svn checkout command. svn checkout *http*://aureport-gui.googlecode.com/svn/trunk/aureport-gui-read-only you can see the sceenshots at http://code.google.com/p/aureport-gui/issues/detail?id=1. Because the old visualized script "mkbar" seems unfit and ugly.I write a new tool with pychart as a substitute for "mkbar". The "aureport-gui" package still contains the "mkbar" script ,which I made some changes to make it look more beautify.But anyway,I don't use it. I have tested the program in fedora 12 ,it requires pychart,and audit packages. and it works well. <liequanche(a)gmail.com> Thanks! cheliequan(a)redflag-linux.com 2010.3.24

Auditing rules maintaining order

by Klaus Heinrich Kiwi

I saw some discussions and patches about audit rules order in this list a few months back, and I'm having some problems maintaining the order of a rules file after they are inputted in a RHEL 5.4 box. My question is: Can we count on the kernel maintaining the order of rules being entered? If so, perhaps those patches weren't included in the RHEL5.4 kernel? I'm attaching my audit.rules file, which renders the following rule listing: [root@bracer2 ~]# auditctl -l LIST_RULES: exit,never dir=/dev/pts (0x8) perm=rw subj_type=qemu_t LIST_RULES: exit,never dir=/var/run/libvirt/network (0x18) perm=wa subj_type=dnsmasq_t LIST_RULES: exit,never dir=/var/log/libvirt/ (0x11) perm=wa subj_type=logrotate_t LIST_RULES: exit,never dir=/var/cache/libvirt/ (0x13) perm=wa subj_type=initrc_t LIST_RULES: exit,always dir=/etc/libvirt/ (0xd) perm=wa key=virt_libvirt_cfg LIST_RULES: exit,always arch=1073741827 (0x40000003) perm=wxa subj_type=qemu_t obj_type!=qemu_t (0x6) key=virt_qemu_crossdomain LIST_RULES: exit,always arch=3221225534 (0xc000003e) perm=wxa subj_type=qemu_t obj_type!=qemu_t (0x6) key=virt_qemu_crossdomain LIST_RULES: exit,always dir=/var/lib/libvirt/images/ (0x18) perm=wa subj_type!=qemu_t key=virt_image_change LIST_RULES: exit,always obj_type=virt_image_t (0xc) perm=wa subj_type!=qemu_t key=virt_image_change LIST_RULES: exit,always dir=/var/run/libvirt/ (0x11) perm=wa subj_type!=virtd_t key=virt_runtime_change LIST_RULES: exit,always dir=/var/lib/libvirt/ (0x11) perm=wa subj_type!=virtd_t key=virt_runtime_change LIST_RULES: exit,always dir=/var/cache/libvirt/ (0x13) perm=wa subj_type!=qemu_t key=virt_runtime_change LIST_RULES: exit,always dir=/var/log/libvirt/ (0x11) perm=wa subj_type!=virtd_t key=virt_log_change LIST_RULES: exit,never watch=/dev/ksm perm=rw subj_type=qemu_t LIST_RULES: exit,never watch=/dev/ptmx perm=rw subj_type=qemu_t LIST_RULES: exit,always watch=/usr/libexec/qemu-kvm perm=x key=virt_qemu_exec LIST_RULES: exit,always watch=/usr/libexec/qemu-kvm perm=wa key=virt_qemu_change LIST_RULES: exit,always watch=/etc/pki/libvirt-vnc/ca-cert.pem perm=wa key=virt_tls_cert LIST_RULES: exit,never watch=/dev/kvm perm=rw subj_type=qemu_t LIST_RULES: exit,always watch=/etc/pki/libvirt-vnc/server-cert.pem perm=wa key=virt_tls_cert LIST_RULES: exit,always watch=/etc/pki/libvirt-vnc/server-key.pem subj_type!=qemu_t key=virt_tls_privkey syscall=all LIST_RULES: exit,always watch=/usr/sbin/libvirtd perm=x key=virt_libvirtd_exec LIST_RULES: exit,always watch=/usr/sbin/libvirtd perm=wa key=virt_libvirtd_change LIST_RULES: exit,always watch=/etc/sasl2/libvirt.conf perm=wa key=virt_libvirt_cfg LIST_RULES: exit,always watch=/etc/sysconfig/libvirtd perm=wa key=virt_libvirt_cfg LIST_RULES: exit,always watch=/etc/pki/CA/cacert.pem perm=wa key=virt_tls_cert LIST_RULES: exit,always watch=/etc/pki/libvirt/private/serverkey.pem subj_type!=virtd_t key=virt_tls_privkey syscall=all LIST_RULES: exit,always watch=/etc/pki/libvirt/servercert.pem perm=wa key=virt_tls_cert Thanks, -Klaus -- Klaus Heinrich Kiwi | klausk(a)br.ibm.com IBM LTC Security Development | http://blog.klauskiwi.com http://www.ibm.com/linux/ltc | http://www.ratliff.net/blog
