The hidden cost of Entropy to your business

Posted on by 1 Comment

On Linux OS, there are two (2) device drivers that provide entropy “noise” for components that require encryption, e.g. the /dev/random and the /dev/urandom device drivers. The /dev/random is a “blocking” device driver. When the “noise” is low, any component that relies on this driver will be “stalled” until enough entropy is returned. We can measure the entropy from a range of 0-4096. Where a value over 1000 is excellent. Any value in the double or single digits will impact the performance of the OS and solutions with delays. The root cause of these delays is not evident during troubleshooting, and typically there are no warning nor error messages related to entropy.

watch -n 1 cat /proc/sys/kernel/random/entropy_avail

The Symantec Identity Suite solution, when deployed on Linux OS is typically deployed with the JVM switch -Djava.security.egd=file:/dev/./urandom for any component that uses Java (Oracle or AdoptOpenJDK), e.g. Wildfly (IM/IG/IP) and IAMCS (JCS). This JVM variable is sufficient for most use-cases to manage the encryption/hash needs of the solution.

However, for any component that does not provide a mechanism to use the alternative of /dev/urandom driver, the Linux OS vendors offer tools such as the “rng-tools” package. We can review what OS RNGD service is available using package tools, e.g. 

dnf list installed | grep -i rng

If the Symantec Identity Suite or other solutions are deployed as standalone components, then we may adjust the Linux OS as we need with no restrictions to add the RNGD daemon as we wish. One favorite is the HAVEGED daemon over the default OS RNGD.

See prior notes on value and testing for Entropy on Linux OS (standalone deployments):

Challenge for vApp

The challenge for Virtual Appliances is that we are limited to what functionality the Symantec Product Team provides for us to leverage. The RNGD service was available on the vApp r14.3, but was disabled for OS challenges with 100% utilization with CentOS 6.4. The service is still installed, but the actual binary is non-executable.

https://knowledge.broadcom.com/external/article/97774/ca-identity-suite-low-entropy-on-virtual.html
https://knowledge.broadcom.com/external/article/139759/ca-identity-suite-142-vapp-rngd-proces.html
https://broadcom-stage.adobecqms.net/us/en/symantec-security-software/identity-security/identity-suite/14-3/virtual-appliance/administering-virtual-appliance/using-the-login-shell.html

A new Virtual Appliance patch would be required to re-enable this RNGD on vApp r14.3cp2. We have access via sudo, to /sbin/chkconfig, /sbin/service to re-enable this service, but as the binary is not executable, we cannot progress any further. We can see the alias in the documentation still exist, but the OS alias was removed in the cp2 update.

However, since vApp r14.4 was release, we can focus on this Virtual Appliance which is running Centos 8 stream. The RNGD service here is disabled (masked) but can be re-enabled for our use with the sudo command. There is no current documented method for RNGD on vApp r14.4 at this time, but the steps below will show an approved way using the ‘config’ userID and sudo commands.

Confirm that the “rng-tools” package is installed and that the RNGD binary is executable. We can also see that the RNGD service is “masked”. Masked services are prevented from starting manually or automatically as an extra safety measure when we wish for tighter control over our systems.

If we test OS entropy for this vApp r14.4 server without RNGD, we can monitor how a simple BASH shell script that emulates a password being generated will impact the “entropy” of /dev/random. The below script will reduce the entropy to low numbers. This process will now impact the OS itself and any components that reference /dev/random. We can observe with “lsof /dev/random” that the java programs will still reference /dev/random; even though most activity is going to /dev/urandom.

Using the time command in the BASH shell script, we can see that the response is rapid for the first 20+ iterations, but as soon as the entropy is depleted, each execution is delayed by 10-30x times.

counter=1;MAX=100;while [ $counter -le $MAX ]; do echo "##########  $counter ##########" ; time dd if=/dev/random bs=8 count=1 2> /dev/null | base64; counter=$(( $counter + 1 )); done;

Enable RNGD on vApp r14.4 & Testing

Now let’s see what RNGD service will do for us when it is enabled. Let’s follow the steps below to unmask, enable, and start the RNGD service as the ‘config’ userID. We have access to sudo to the Centos 8 Stream command of /sbin/systemctl.

sudo /usr/bin/systemctl status rngd.service
ls -lart /etc/systemd/system/rngd.service
sudo /usr/bin/systemctl unmask rngd.service
sudo /usr/bin/systemctl enable rngd.service
cat /usr/lib/systemd/system/rngd.service
sudo /usr/bin/systemctl start rngd.service
sudo /usr/bin/systemctl status rngd.service
ps -ef | grep rngd | grep -v grep

After the RNGD service is enabled, test again with the same prior BASH shell script but bump the loops to 1000 or higher. Note using the time command we can see that each loop finishes within a fraction of a second. 

counter=1;MAX=1000;while [ $counter -le $MAX ]; do echo "##########  $counter ##########" ; time dd if=/dev/random bs=8 count=1 2> /dev/null | base64; counter=$(( $counter + 1 )); done;

Summary

Aim to keep the solution footprint small and the right-sized to solve the business’ needs. Do not accept the default performance; avoid over-purchasing to scale to your expected growth.

Use the JVM switch wherever there is a java process, e.g. BLC or home-grown ETL (extract-transform-load) processes.

-Djava.security.egd=file:/dev/./urandom

If you suspect a dependence may impact the OS or other processes on /dev/random, then enable the OS RNGD and perform your testing. Monitor with the top command to ensure RNGD service is providing value and not impacting the solution.

Rollback for Active Directory and Mainframe (TSS/ACF2/RACF) Entitlements

Posted on by Leave a comment

One business risk to manage when new business logic is being promoted to production environments is how to plan for a rollback process, where prior state data is restored, especially for an application/endpoint that is critical for a business; and as important to users as their login credentials and access.

In this entry, we showcase how to use CA Directory to snapshot an endpoint on a scheduled basis (daily/hourly) and have the process prepare a rollback delta file for user’s entitlements.

Understanding how queries may be direct to an endpoint/application or via the CA Identity Manager provisioning tier, we can speed up this process rapidly for sites that have millions of identities in an endpoint.

Avoid the noise – IMPS etatrans alias/function “tap”

Posted on by Leave a comment

Monitoring use-cases within solutions that use various logs can be onerous when there is “noise” or low-value events in the logs. For provisioning use-cases, we prefer to focus on the “CrUD” use-cases and actions.

The CA/Symantec Identity Manager solution has a mid-tier component, IM Provisioning Server, that captures quite a bit of information useful for monitoring for success/failure. The default Log Level of the primary log file, etatrans*.log, is log level = 7. This log level will capture all possible searches and information of activity within the Provisioning Server’s service and transactions to its connector tier.

We can reduce some of the “noise” of searches/information and focus on the “CRuD” actions of “add/mod/del” by reducing the log level to level = 3.

This help as well to reduce the impact to the disk spaces and roll-over of the etatrans*.log file during bulk tasks or feed tasks.

Challenges:

However, even with log level = 3, we still have some “noise” in the etatrans*.log.

Additional “pain points”, the etatrans*.log file is renamed upon every restart of the IMPS service and during rollover at a size of 1 MB.

Resolution:

To assist with “finding” the current file, and to remove the noise, we have created the following “function/alias” for the IMPS user ID.

  1. Log into the IMPS service ID: sudo su – imps {Ensure you use the “dash” character to ensure the .profile is sourced when you switch IDs}
  2. Edit the .profile file: vi .profile
  3. The current file will only have one line, that sources the primary IMPS environmental information: . /etc/.profile_imps

4. Add the following body after the IMPS environmental profile line

function tap () {
cd $ETAHOME/logs
a=$(ls -rt $ETAHOME/logs | grep etatrans | tail -1)
pwd
echo "Tail current log file with exclusions: "$a
tail -F $a | grep -v -e ":LDAP" -e ":Config" -e "AUDITCONFIG" -e ":EtaServer" -e ":Bind " -e ":Unbind " -e ":Search "
}
export -f tap

This new “function/alias” will cd to the correct folder of logs, then tail the correct etatrans*.log file, and exclude the noise of non-CrUD activity. Using the new alias of “tap” on all provisioning servers, will allow us to isolate any challenges during use-case validation.

5. Exit out of the IMPS user ID account; then re-sudo back into this account, and test the “tap” alias.

6. While using the “tap” alias, exercise use-cases within the IM Provisioning Manager (GUI) and the IM User Console (browser); monitor the “Add/Mod/Deletes”. You will also be able to see the “Child” updates to endpoints and updates to the IMPS notification queue (IME Callback).

Using X11 on Virtual Appliances

Posted on by Leave a comment

In this blog example, we will explore expanding the ability of Virtual Appliances to use X11 programs where possible instead of requiring a 2nd server to host the solutions’ client tools.

We will review how to enable the following client tools: CX (Symantec IM Connector Xpress), WF Designer (Symantec Workflow Designer), Wildfly/JBOSS Management UI, Jxplorer (LDAP Management UI), and Apache Directory Studio (LDAP Management UI). Note there is no java version for the Symantec Identity Manager GUI (32bit VC++ client)

Challenge:

The Symantec Identity Suite Virtual Appliance is locked down from updating libraries as the ‘root’ user and the default login service ID of ‘config’ does not have access to the package installer, e.g. yum.

The Symantec Identity Suite Virtual Appliance like other tools, have an enhancement request process to add new functionality. While we wait for this to be delivered, we can address these gaps ourselves with knowledge of what X11 functionality is required to be enabled with the limited resources we have available to ourselves.

https://community.broadcom.com/participate/ideation-home/viewidea?IdeationKey=34adb887-a1c0-4d59-a977-4b65f4274425

To first identify what drivers may be needed, we can use the Linux OS “strace” command to capture which files are “open” or “openat” and used by the programs.

Example for tracing the files/drivers for Java (Oracle or AdoptOpenJDK) jconsole program:

STRACE

Using “strace -e trace=open,openat /opt/CA/java/bin/policytool” we can see the files that were found ” = 3″ versus those not found “= -1 ENOENT (No such file or directory)”. Some files are required for Centos 8 Stream and others for Centos 6.4

Using this iterative process above will help to identify either the primary file used or a supporting file required to start and use the UI version of the program.

We can use both Java jconsole or policytool to help identify the drivers required. There may be a different of drivers version or additional ones require for the OS of the virtual appliances.

Trace Example with Java Policytool program and compare between Centos 8 Stream (openat) and Centos 6.4 (open)

Now that we have a process to help identify the drivers required, we can walk through the challenges and the value statement.

First challenge for X11 access, is the DISPLAY environment variable must be defined. Otherwise we will see this error message: “No X11 DISPLAY variable“

To address this challenge, we could manually set this value every time, but why not use our bash shell to manage this.

DISPLAY OS Variable

Add the below two (2) lines to config’s .bash_profile

DISPLAY=$(who -m | gawk -F'(' '{ print $2}' | gawk -F')' '{print $1}'):0.0;export DISPLAY
env | grep DISPLAY

Our DISPLAY variable will now be updated every time we log into the vApp with the config userID.

We should now see this:

When using the “strace” method, we may see that we have a file on the OS, but it is reporting it as not found due to an internal dependency.

Example for policytool, we can see that the file libXext.so.6 (or link) is not referenced correctly.

If we search the OS of the vApp, we can find this file (and its link) with no issue.

The file libXext.so.6 (or libXext.so.6.4.0) requires a supporting file of libX11.so.6 (libX11.so.6.3.0). As we search for these files, we can now start collecting them from nonVapp OS servers (that do have access to package updates), and make them available to the ‘config’ userID via scp/rsync.

On another server, that has these file (same OS release), find and copy these files.

After we have identified all the required files that are missing from the vApp r14.3 (Centos 6.4) or r14.4 (Centos 8 Stream), we can package them up for the ‘config’ userID and scp/rsync them to the vApp.

Soft Links

Before we use these files, we may need to validate that the soft-links are properly defined. If you have any issues, use strace to help identify the missing soft-link to the real file.

LD_LIBRARY_PATH

LD_LIBRARY_PATH is the OS variable we will use to redirect the libraries files (x86/x64) for the ‘config’ userID. Again edit the config’s .bash_profile and ensure the following lines exist:

#### ANA - Add X11 process & supporting libraries to vApp r14.3 config service ID ####
DISPLAY=$(who -m | gawk -F'(' '{ print $2}' | gawk -F')' '{print $1}'):0.0;export DISPLAY
env | grep -i DISPLAY

LD_LIBRARY_PATH=/tmp/x11_libraries_for_centos6_vapp143/usr/lib64:/tmp/x11_libraries_for_centos6_vapp143/usr/lib;export LD_LIBRARY_PATH
env | grep -i LD_LIBRARY_PATH
#### ANA - Add X11 process & supporting libraries to vApp config service ID ####

OR

#### ANA - Add X11 process & supporting libraries to vApp r14.4 config service ID ####
DISPLAY=$(who -m | gawk -F'(' '{ print $2}' | gawk -F')' '{print $1}'):0.0;export DISPLAY
env | grep -i DISPLAY

LD_LIBRARY_PATH=/tmp/x11_for_centos8_for_vapp144/usr/lib64:/tmp/x11_for_centos8_for_vapp144/usr/lib;export LD_LIBRARY_PATH
env | grep -i LD_LIBRARY_PATH
#### ANA - Add X11 process & supporting libraries to vApp config service ID ####

We should now see the following upon login:

Wildfly / JBoss CLI X11 UI

Use for managing the standalone-full-ha.xml file via jboss-cli.sh scripts and to update values.

Ensure you have created a management user credential to access the running Wildfly/JBoss release.

Next Steps

We can use the X11 functionality for the IM Workpoint Designer tool, the Connector Xpress (CX) UI tool, and any other tools, e.g. Symantec Layer7 Management UI (manager.jar)

Side Note:

The IM Workpoint Designer tool and other tools have been removed from the vApp r14.4 IAMSuite samples.

Installed IAMSuite tools only under config service ID, to determine if there is any value. Do not see any X11 client applications under this installed component.

Workpoint Designer

Extract the workpoint designer from the standalone deployment tools to a media folder.

Update the shell script files to be executable, replace the localhost entry for another host alias that will resolve to an IP address that the IM solution with Workpoint is actively listening to. Then run the designer from the virtual appliance.

config@vapp14401 VAPP-14.4.0 (192.168.2.210):~/media > unzip CA-IG_WorkpointDesigner.zip  > /dev/null
config@vapp14401 VAPP-14.4.0 (192.168.2.210):~/media > cd CA-IG_WorkpointDesigner/Workpoint/WorkPointDesigner/bin/

config@vapp14401 VAPP-14.4.0 (192.168.2.210):~/media/CA-IG_WorkpointDesigner/Workpoint/WorkPointDesigner/bin > ./Designer.sh

Reduce the complexity of the library paths for EJB and reduce it within the bin/init.sh file:
EJB_CLASSPATH=../lib/:../lib/axis/:../rcm/*
Why? We noted path issues that certain file name versions were NOT updated in the referenced init.sh and rcmClassPath.sh, so we now just directly reference the library folders instead.
Also, set the JBOSS_HOME to point to IG wildfly folder. [Note: This works for Wildfly 8 and 15]

If you are unsure if you are missing ANY Java libraries, use the -verbose:class switch in Designer.sh file to showcase EVERY jar file loaded. This will be very verbose but helpful.

If we need help to find a class within a jar file, we can use find with unzip and grep to find the class by a string value. Save the below bash shell as find_jar.sh and execute it with the class string you want.

#!/bin/bash
printf "Searching JARs for string '${1}'...\n"
find . -iname '*.jar' -printf "unzip -c %p | grep -iq '${1}' && echo %p\n" | sh

Connector Xpress

Connector Xpress only has a MS Windows installer, but we can still use this component on Linux OS. Install the CX UI on MS Windows, then zip up the installed folder with all sub-folders. Copy this compress file over to a media folder for the ‘config’ userID and extract the file.

Review the startup file of “ConnectorXpress.bat” and we will create a version for Linux OS. Copy the last line with the conxp.jar file to a new bash script file. Update the file path from MS Windows format, to Linux OS format.

We can now use CX UI from the vApp.

Restart remote IMPD DATA DSAs after long outage

Posted on by Leave a comment

“DSA is attempting to start after a long outage, perform a recovery procedure before starting”

Challenge:   The IMPD (Identity Manager Provisioning Directory) Data DSAs have been offline for a while, e.g. 7 days+ (> 1 week), and the Symantec/CA Directory solution will, to protect the data, refuse to allow the DATA DSAs to start unless there is manual intervention to prevent the possibility of production data (Live DATA DSAs) being synced with older data (Offline DATA DSAs).

If we were concern, we would follow best practices and remove the offline DATA DSAs’ *.db & *.dp files, and replace the *.db with current copies of the Live DATA DSAs’ *.db files; generate temporary time files of *.dx and allow the time files of *.dp to rebuild themselves upon startup of the offline DATA DSAs.

However, if we are NOT concern, or the environment is non-production we can avoid the multiple shells, multiple commands to resync by using a combinations of bash shell commands. The proposal below outlines using the Symantec/CA Identity Suite virtual appliance, where both the IMPD and IMPS (Identity Manager Provisioning Server) components reside on the same servers.

Proposal:   Use a single Linux host to send remote commands as a single user ID; sudo to the ‘dsa’ and ‘imps’ service IDs, and issue commands to address the restart process.

Pre-Work:   For the Identity Suite vApp, recommend that .ssh keys be used to avoid using a password for the ‘config’ user IDs on all vApp nodes.

Example to setup .SSH keys for ‘config’ user ID: https://anapartner.com/2020/05/01/avoid-locking-a-userid-in-a-virtual-appliance/

If using .SSH keys, do not forget to use this shortcut to cache the local session: eval `ssh-agent` && ssh-add

Steps:   Issue the following bash commands with the correct IPs or hostnames.  

If possible, wrap the remote commands in a for-loop. The below example uses the local ‘config’ user ID, to ssh to remote servers, then issues a local su to the ‘dsa’ service ID. The ‘dsa’ commands may need to be wrapped as shown below to allow multiple commands to be executed together. We have a quick hostname check, stop all IMPD DATA DSAs, find the time-stamp file that is preventing the startup of the IMPD DATA DSAs and remove it, restart all IMPD DATA DSA, and then move on to the next server with the for-loop. The ‘imps’ commands are similar with a quick hostname check, status check, stop and start process, another status check, then move on to the next server in the for-loop.

for i in {136..141}; do ssh  -t config@192.168.242.$i "su - dsa -c \"hostname;dxserver stop all;pwd;find ./data/ -type f \( -name '*.dp' \) -delete  ;dxserver start all \" "; done

for i in {136..141}; do ssh  -t config@192.168.242.$i "su - imps -c \"hostname;imps status;imps stop;imps start;imps status \" "; done

Additional: Process to assist with decision to sync or not sync.

Check if the number of total entries in each individual IMPD DATA DSA match with their peers (Multi-Write groups). Goal: Avoid any deltas > 1% between peers. The IMPD “main”, “co”, “inc” DATA DSA should be 100% in sync. We may see some minor flux in the “notify” DATA DSA, as this is temporary data used by the IMPS server to store data to be sent to the IME via the IME Call Back Process.

If there are any deltas, then we may export the IMPD DATA DSAs to LDIF files and then use the Symantec/CA Directory ldifdelta process to isolate and triage the deltas.

NOTIFY DSA is temporary data and will have deltas. This DSA is used for the IME CALL BACK process.
