Compliance Check

Before a Managed OS VM can go into the Full Managed state, compliance checks must be run. Only if all relevant checks are successfully passed, the VM will be transferred to the respective state. If one or more tests are not successful, then this must be corrected by the customer. Afterwards the state change can be requested again.

The compliance check will be executed when the following state changes are requested:

• Temp Admin to Customer Maintenance
• Temp Admin to Full Managed

Compliance Checks for Managed RHEL 7 and Managed RHEL 8

This section describes the checks to be executed before offering the Full Managed state on a given system.
To see whether a system is healthy i.e. able to be changed back to Full Managed state, run the following command from the command line at anytime:

$ sudo checkmate -a

The output of the command is written to standard output and to /var/log/messages.

Check	Explanation	Troubleshooting
check_autofs	It's not allowed to have the autofs-rpm installed. Therefore, it must be removed.	Remove the autofs-rpm by executing: $ sudo yum -y remove autofs.x86_64
check_cron	There are no crontab entries allowed which run as user root. There are only dedicated root cronjobs which sha1sum checksums are trusted from check_cron, due to that, it's not allowed to edit existing cronfiles.	If the cronjob is absolutely needed, send an incident to the Managed OS operation team explaining why the cronjob is needed. Also provide the exact error message, the hostname and the ip-address.
check_fs_content	Ensure you create no additional content on the OS mountpoints. No application directories, application logfiles or any other application data is allowed on os mounted filesystems (/, /boot, /usr/local, /usr/local, /opt, /opt/ds_agent, /opt/vmware, /home, /var, /var/log, /var/log/audit, /tmp). Create all your application specific content on additionally added disks which belongs to the LVM volume group "datavg".	Proposed valid procedure: 1. Add a disk for every new mountpoint you want to create via the portal. 2. Add the new disks to the LVM volume group "datavg". 3. Create a new LVM logical volume for every custom mountpoint. 4. Alter /etc/fstab 5. Mount the new filesystems. 6. Test the new filesystems.
check_fslayout	The OS requires the following filesystem layout: /dev/mapper/vrhvg-slashlv / /dev/mapper/vrhvg-optlv /opt /dev/mapper/vrhvg-homelv /home /dev/mapper/vrhvg-usrloclv /usr/local /dev/sda1 /boot /dev/mapper/vrhvg-tmplv /tmp /dev/mapper/vrhvg-varlv /var /dev/mapper/vrhvg-varloglv /var/log /dev/mapper/vrhvg-logaudlv /var/log/audit /dev/mapper/vrhvg-swaplv01 swap All OS filesystems must be in the volume group "vrhvg". All customer filesystems must be in the volume group "datavg" or "datavg[0-9][0-9]". The size of the OS filesystems must not be changed.	You can check the filesystem layout by executing: $ df -hP
check_fstab	Checks if all entries from /etc/fstab are mounted. All entries from /etc/fstab must be mounted before switching back to Full Managed state.	To test your fstab configuration, you can mount everything in it by executing: $ sudo mount -a
check_fstypes	Ensure all partitions have an allowed file system type. Allowed filesystem types: autofs, binfmt_misc, cgroup, cifs, configfs, debugfs, devpts, devtmpfs, ext4, hugetlbfs, mqueue, nfs, nfs4, proc, pstore, rootfs, securityfs, selinuxfs, smbfs, swap, sysfs, tmpfs, usbfs, xfs	You can check the filesystem type of a mounted filesystem by executing: $ df -hT [FILESYTEM]
check_hostname	Checks if the hostname has not been changed. If you have tried to change the hostname, you must revert all changes.	You can make sure all relevant places have the right hostname set by executing: $ sudo grep sccloudres /etc/sysconfig/rhn/systemid $ sudo facter fqdn $ sudo cat /etc/hostname $ sudo grep sccloudres /etc/sysconfig/network $ sudo grep sccloudres /etc/hosts $ hostnamectl status | grep sccloudres
check_hosts_file	The /etc/hosts file must contain a localhost entry and all IPv4 and IPv6 addresses must be valid.	Get an overview about your actual /etc/hosts file by executing: $ ls -la /etc/hosts && cat /etc/hosts
check_local_users	Ensure that there are no local users with root permissions except for the user root. Ensure the GID for users and groups are not higher than 99999, as this GIDs are reserved for Groups which are managed in the Active Directory Ressource Domain. Ensure no local group "dl_esc-mos-lnx-access*" exists as these groups are managed in the Active Directory Ressource Domain.	You can change the UID of a user by executing: $ sudo usermod -u [NEWUID] [USER] You can change the GID of a group by executing: $ sudo groupmod -g [NEWGID] [GROUP]
check_lvm	Checks if the pvs command finds no unknown/missing devices.	You can start debugging this issue by executing: $ sudo pvs
check_malware	There must not be any malware protection installed, besides the malware protection installed by Swisscom.
check_malware_inst	Ensure Deep Security is installed, configured, and running.	You get information about the relevant services by executing: $ sudo systemctl status puppet $ sudo systemctl status ds_agent
check_monitoring_inst	Ensure the Swisscom monitoring agent is installed and running. Puppet is installing the monitoring agent, if the check fails because the monitoring agent is not installed, check why Puppet is not running.	You get information about the relevant services by executing: $ sudo systemctl status node_exporter $ sudo ps aux | grep node_exporter | grep -v grep
check_pam_config	Ensure the pam RPM is installed. Pam configuration must not have been changed or must match an accepted configuration.	Install the pam-rpm, in case it is missing, by executing: $ sudo yum -y install pam.x86_64 Also make sure to not alter or add any files to /etc/pam.d.
check_reboot	Ensure the OS does not require a reboot, otherwise you must reboot the OS.	Install the yum-utils-rpm, in case it is missing, by executing: $ sudo yum -y install yum-utils.noarch Reboot your server in case it is necessary by executing: $ sudo shutdown -r now
check_repos	Ensure there aren't any unreachable repos configured.	Troubleshoot your issues according to the error-message provided. In case you need to update packages, you may do so by executing: $ sudo yum -y update
check_rhel_version	The OS version must be any of the following: - RHEL 7.4 or higher minor release - RHEL 8.0 or higher minor release	You can check your OS- and kernel-version by executing: $ cat /etc/redhat-release && uname -a
check_root_processes	Ensure only dedicated system processes are running as root. Applications must not run as root.	You get a list of all processes with the running user by executing: $ sudo ps auxf
check_rpm	The system packages must be from Redhat and must not be modified.	In case of an error, check what has changed on the package $ rpm -V [PACKAGE] try to fix the problem with a reinstall of the package by executing: $ sudo yum reinstall [PACKAGE]
check_satellite	Ensure the host is registered to the Red Hat satellite server from Swisscom.	In case of an error, check if a proper Satellite server is configured by executing: $ grep cms2capsule /etc/rhsm/rhsm.conf
check_scs_puppet	Ensure puppet agent is installed and has configured the dedicated puppet master from Swisscom. Puppet must run without errors.	You can start debugging this issue by executing: Is the Puppet RPM installed? $ sudo rpm -qa --last | grep puppet Is the Puppet-Service enabled and running? $ sudo systemctl status puppet Is a Swisscom Puppet-Server defined in /etc/puppetlabs/puppet/puppet.conf? $ grep '^server\=' /etc/puppetlabs/puppet/puppet.conf Is the Puppet-Run without errors? (all green) $ sudo puppet agent -t
check_selinux	Ensure selinux is enabled (permissive or enforcing).	You can start debugging this issue by executing: Is getenforce returning Enforcing or Permissive? $ sudo getenforce Is selinuxenabled returning the return code 0? $ selinuxenabled && echo $? Is /etc/selinux/config containing SELINUX=enforcing or SELINUX=permissive? $ sudo grep '^SELINUX\=' /etc/selinux/config
check_snmp	If a SNMP daemon/service is configured and running on the system, only read-access and SNMPv3 is allowed. Write access is disallowed.	In case of an error, check for disallowed directives in /etc/snmp/snmpd.conf by executing: $ grep rw /etc/snmp/snmpd.conf 2>/dev/null $ grep write /etc/snmp/snmpd.conf 2>/dev/null
check_space	Ensure minimum free space: / > 1 GB /boot > 100 MB /var/log > 200 MB /tmp > 500 MB /var/log/audit > 100 MB /opt > 50 MB swap > 1 GB   Ensure minimum free space on volume groups: vrhvg > 5GB	You can compare the free space with the figures here by executing: $ df -hP
check_ssh	Ensure sshd is running and the configuration file exists. Ensure sshd is running with the default configuration file. Ensure sshd has a minimal sane configuration. Only allowed ciphers are enabled/configured. Allowed MACs: hmac-sha2-512,hmac-sha2-256 Allowed Ciphers: aes256-ctr,aes128-ctr Allowed kexalgorithms: diffie-hellman-group-exchange-sha256	In case of an error, try to solve the problem according to the instruction given in the error message. Rerun the check by executing: $ sudo checkmate -c -f -I check_ssh
check_ssh_keys	Ensure root doesn't have any unknown ssh keys installed in /root/.ssh/authorized_keys, otherwise you must remove the unknown ssh keys.	In case of an error, make sure to remove all keys from roots authorized keys file. You can check roots authorized keys by executing: $ sudo cat /root/.ssh/authorized_keys 2>/dev/null
check_sudo_processes	There must not be any sudo process running.	Stop the mentioned process, otherwise it will not be possible to leave the Temp Admin state.
check_sudoers	There must not be any sudoers configurations (aliases etc.) that allow a user to acquire root-privileges. Only trusted sudoers configurations are allowed, which means each sudoers configuration needs to be requested with a CRQ from ManagedServicesLNX	Try to avoid sudo configurations, better use the Temp Admin state for administration tasks. If the sudo command is absolutely needed, send an incident to the Managed OS operation team explaining why the sudo file is needed. Also provide the sudo file, the hostname and the ip-address.
check_suid	There must not be any unknown setuid binaries. Filesystems which are mounted with the "nosuid" option, are excluded from this check. To prevent a long running search for files with the suid bit set, mount the application or nfs filesystems with the "nosuid" option.	In case of an error, try to solve the problem according to the instruction given in the error message. Rerun the check by executing: $ sudo checkmate -c -f -I check_suid
check_update_age	Determine last patch date.

Run Compliance Checks manually

Managed Windows

The compliance checks for Managed Windows OS on Swisscoms ESC are run using a custom build framework called PccComplianceChecks or PCC for short.

Each time a compliance check is run, the PCC is called behind the curtains and it triggers a so called PccRun.

A PCCRun is the operation that runs when an Exit Temp Admin is launched in the Portal or system is returned to Full Managed mode for instance.

A PccRun executes a number of infrastructure related tests to validate the OS running in the VM is compliant with Swisscoms Managed OS standards. The module has been made publicly available so that compliance checks can be run locally on the Managed Windows OS.

PCC is locally available to ESC customers starting with version 1.0.0 of the PccComplianceChecks package.

Why use PCC manually

Executing an ExitTempAdmin or Return to Full Managed mode via the regular Day 2 Action can last a few minutes and potentially result in failing checks that need to be corrected. To simplify and to speed up this process, it is now possible to call the same tests that run during the Return to Full Managed mode but directly on your VM.

The main benefit of doing so is the gain in time in validating that the OS is Swisscom standards conform before executing the Return to Full Managed action.

With PCC, it is also possible to get a history of the past runs.

Verify the local PCC version

IMPORTANT NOTE: To download and install the latest versions of the PCC Framework and the required module "PCC.CHK.ESC.WIN.MOS" locally, we recommend to execute first an "Exit Temp Admin" or "Return To Full Managed" Day 2 Action in the ESC Portal.

Open a PowerShell prompt and execute the following PowerShell command(s):

Step 1 - Identify the current version of PCC

This request is used to get the current version of PCC working on your Managed Windows OS.

Request

Get-Module PccComplianceChecks -ListAvailable

Note: One or more different PCC versions can co-exist on the same machine. The one with the highest version number is the latest version available.

Execute a PCCRun

Open a PowerShell prompt and execute the following PowerShell command(s):

Step 1 - Execute a PCCRun

Only messages of the failed checks will be displayed on screen. If none are shown, it means that the Managed Windows OS is compliant.

Request

Test-TempAdmin

Step 2 - Optional

Alternatively, it is possible to output directly the run using the following snippet.

Request

Test-TempAdmin -ShowRun

Get all past PCC run results

NOTE: Results can only be retrieved from compliance checks that have run using the PccComplianceChecks version 1.2.0 or above. Any run done with a previous version will not generate the needed PccRunDocument.

Open a PowerShell prompt and execute the following PowerShell command(s):

Step 1 - Retrieve all past PCC run results

Request

Get-PccRundocument

Note: The 'ErrorCount' property indicates how many compliance checks have failed during that specific run.

Step 2 - Retrieve the last PCC run result

Results will look similar to the screen shot below but will vary according to the VM and its current compliance.

Request

Get-PccrunDocument -Latest

Step 3 - Get failed checks from the last pcc run results

To get the list of the failed checks from the last PCC run (or failed Return to FullAdmin) execute the following code. Results will look similar to the screen shot below but will vary according to the VM and its current compliance.

Request

(Get-PCCRunDocument -Latest).GetFailedChecksConcise()

Managed RHEL

If the VM is in Temp Admin state, the compliance check can also be performed manually.
The command below can be used to check whether the VM can be successfully transferred to the Full Managed state.

$ sudo checkmate -a
