Clean Install of TOS Aurora on GCP

Overview

This procedure is for the clean installation of TOS Aurora on Google Cloud Platform (GCP). To add a node to an existing cluster, see Adding a Node on GCP. For all other installation and upgrade options, see Installing and Upgrading.

Tufin Orchestration Suite (TOS Aurora) includes SecureTrack, SecureChange and SecureApp. You will specify the applications you want to enable, when you run the install command.

Tufin Orchestration Suite should be treated as high-risk security resource, similar to how you would treat any LDAP product (for example, Active Directory). Therefore, you should only install Tufin Orchestration Suite in an appropriately secured network and physical location, and only authorized users should be granted access to TOS products and the operating system on the server.

After the installation you will have created a single data node TOS cluster to which you can add additional worker nodes. This node is the primary data node, and there is no need to install TOS on any additional nodes. Worker nodes require an operating system only, and with high availability, data is replicated between the nodes.

UDP traffic is not supported in GCP. To use UDP traffic, instead of creating a load balancer in GCP, you will create the load balancer when installing TOS using built-in software.

High Availability (HA)

High availability is supported for GCP over three availability zones, giving you a higher level of resilience and availability when deploying on this cloud platform. Note that all availability zones must be in the same region. See High availability.

Remote Collectors (RCs)

Remote collectors can be deployed on GCP. They are supported in and between different GCP regions.

Prerequisites

You must know the resources you will need - CPU cores, RAM, disk space and the load-model parameter <LOAD>, provided by your account team, based on the procedure Calculate resources - clean install.
All resources need to be dedicated to the TOS Aurora machine. Do not use shared CPU or memory and if the datastore is shared, the disk performance must meet the requirements at all times.
Do not install any software on your server before or after the deployment of TOS Aurora that is not specified in the current procedure.
Select a storage type of SSD. Take into consideration that TOS requires 7,500 IOPS and the throughput expected will average 250MB/s with bursts of up to 700MB/s.
You will need to allow access to required Ports and Services.
Allocate a 24-bit CIDR subnet for the Kubernetes service network and a16-bit CIDR subnet for the Kubernetes pods network (10.244.0.0/16 is used by default).

The pods and services networks must be inside the following private networks: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16. In addition, ensure that the dedicated CIDR for the service network and pods network don't overlap with:
- Each other
- The physical addresses of your TOS Aurora servers (see below)
- Your primary VIP, Syslog VIP or external load balancer IP (see below)
- Any other subnets communicating with TOS or with TOS nodes
Once TOS Aurora has been installed, changing the host name or IP address will require reinstalling - see Changing IP Address/Host Names. If you want to change the host name of the node, do so before running the tos install command.

You will need to configure three partitions: /opt, /tmp and /var, as well as a separate disk for etcd. The /opt partition will contain your data, which will increase over time. Most of your available disk space should be allocated to this partition and the minimum is determined by the load model parameter (small, medium, large) provided by your account team. Minimum sizes for all partitions:

Minimum Partition Sizes

/opt/

(Small)*

/opt/

(Medium)*

/opt/

(Large)*

/tmp/

128 GB

Worker node (central and remote clusters)

70 GB

25 GB

60 GB

N/A

*Small, medium and large refer to the load model parameter provided by your account team.

We recommend allocating /opt partition all remaining disk space after you have partitioned the other directories.

For PGA, if you are using NFS your backup server needs to be running NFS 4.

From PHF1.0.0 and later, if you are running NFS 3 on your backup server it will not work because of a security vulnerability. If you want to ignore the security vulnerability to enable NFS 3, you need to run the following commands on all TOS servers that are using TufinOS 4.20 and later:
```
systemctl unmask rpcbind.socket rpcbind.service
```
systemctl unmask rpcbind.socket rpcbind.service
```
systemctl start rpcbind.socket rpcbind.service
```
systemctl start rpcbind.socket rpcbind.service
```
systemctl enable rpcbind.socket rpcbind.service
```
systemctl enable rpcbind.socket rpcbind.service
The TOS installation removes all TOS files, directories and backups left on the machine from old deployments. If you have any files you want to keep, move them to a safe external location before starting this procedure.

See the Important Installation Information in the R24-2 Release Notes.

Create the Metal LB Load Balancer - for UDP Traffic support
The Metal LB load balancer is configured when installing TOS using built-in software. This requires configuring an alias IP address.
1. Edit the VM instance.
2. Go to Networking > Network Interfaces.
3. In the Custom ephemeral IP Address field, add the primary VIP.
4. Add two Alias IP ranges for the load balancer VIP and syslog VIP.
  
  If you need additional syslog VIPs, add more alias IP ranges, For more information, see Syslog VIP Addresses.
Copy these VIP addresses to a separate location. You will need them when running the tos install command.

Create Firewall Rules
Repeat this step for each of the ports you open.

For more information, see the vendor documentation Create a new firewall rule.
1. Navigate to VPC Network > Firewall
2. Click CREATE FIREWALL RULE

Connect to the VM Using SSH
To connect via ssh you can add an existing ssh key to GCP via UI or use the gcloud utilily to generate key and add it.

To generate a key using gcloud:
1. Download gcloud to your workstation.
2. Run gcloud auth login command to login to your account. Variable <PROJECT_ID> can be set once globally to avoid entering it each time.
  gcloud config set project "<PROJECT_ID>"
  
  gcloud config set project "<PROJECT_ID>"
  gcloud compute ssh --zone "<ZONE>" "<VM_INSTANCE_NAME>"
  
  gcloud compute ssh --zone "<ZONE>" "<VM_INSTANCE_NAME>"
Configure Partitions

If not done already, set up partitions according to the Prerequisites.
Configure the Operating System
1. If you are not currently logged in as user root, do so now.
  [<ADMIN> ~]$ su -
  
  su -
2. If you want to change the host name or IP of the machine, do so now. Once TOS Aurora has been installed, changing the host name or IP address will require reinstalling - see Changing IP Address/Host Names. To change the host name, use the command below, replacing <mynode> with your preferred name.
  [<ADMIN> ~]# hostnamectl set-hostname <mynode>
  
  hostnamectl set-hostname <mynode>
3. Modify the environment path to run TOS CLI commands without specifying the full path (/usr/local/bin/tos).
  [<ADMIN> ~]# echo 'export PATH="${PATH}:/usr/local/bin"' | sudo tee -a /root/.bashrc > /dev/null
  
  echo 'export PATH="${PATH}:/usr/local/bin"' | sudo tee -a /root/.bashrc > /dev/null
4. Synchronize your machine time with a trusted NTP server. Follow the steps in Configuring NTP Using Chrony.
5. Configure the server timezone.
  [<ADMIN> ~]# timedatectl set-timezone <timezone>
  
  timedatectl set-timezone <timezone>
  where <timezone> is in the format Area/Location. Examples: America/Jamaica, Hongkong, GMT, Europe/Prague. List the time-zone formats that can be used in the command.
  [<ADMIN> ~]# timedatectl list-timezones
  
  timedatectl list-timezones
6. Upgrade the kernel:
  [<ADMIN> ~]# dnf upgrade
  
  dnf upgrade
7. Disable SELinux:
  - If file /etc/selinux/config exists, edit and change the value of SELINUX to disabled:
    SELINUX=disabled
  - If the file doesn't exist or SELINUX is already set to disabled, do nothing.
8. Reboot the machine and log in.
9. Install Wireguard. This is needed to encrypt communication between nodes (machines) within the cluster. See Install Wireguard and follow the steps for your Linux distribution.
10. Reboot the machine and log in.
11. Install tmux and rsync:
  [<ADMIN> ~]# dnf install -y rsync tmux
  
  dnf install -y rsync tmux
12. Disable the firewall:
  [<ADMIN> ~]# systemctl stop firewalld
  
  systemctl stop firewalld
  [<ADMIN> ~]# systemctl disable firewalld
  
  systemctl disable firewalld
13. Create the TOS Aurora load module configuration file /etc/modules-load.d/tufin.conf. Example using vi:
  [<ADMIN> ~]# vi /etc/modules-load.d/tufin.conf
  
  vi /etc/modules-load.d/tufin.conf
14. Specify the modules to be loaded by adding the following lines to the configuration file created in the previous step. The modules will then be loaded automatically on boot.
  br_netfilter wireguard overlay ebtables ebtable_filter
  
  br_netfilter wireguard overlay ebtables ebtable_filter
15. Load the above modules now:
  [<ADMIN> ~]# cat /etc/modules-load.d/tufin.conf |xargs modprobe -a
  
  cat /etc/modules-load.d/tufin.conf |xargs modprobe -a
  Look carefully at the output to confirm all modules loaded correctly; an error message will be issued for any modules that failed to load.
16. Check that Wireguard has loaded correctly.
  [<ADMIN> ~]# lsmod |grep wireguard
  
  lsmod |grep wireguard
  The output will appear something like this:
```
wireguard              201106  0
ip6_udp_tunnel         12755  1 wireguard
udp_tunnel             14423  1 wireguard
```
  If Wireguard is not listed in the output, contact support.
17. Create the TOS Aurora kernel configuration file /etc/sysctl.d/tufin.conf. Example using vi:
  [<ADMIN> ~]# vi /etc/sysctl.d/tufin.conf
  
  vi /etc/sysctl.d/tufin.conf
18. Specify the kernel settings to be made by adding the following lines to the configuration file created in the previous step. The settings will then be applied on boot.
  net.bridge.bridge-nf-call-iptables = 1 fs.inotify.max_user_watches = 1048576 fs.inotify.max_user_instances = 10000 net.ipv4.ip_forward = 1
  
  net.bridge.bridge-nf-call-iptables = 1 fs.inotify.max_user_watches = 1048576 fs.inotify.max_user_instances = 10000 net.ipv4.ip_forward = 1
19. Apply the above kernel settings now:
  [<ADMIN> ~]# sysctl --system
  
  sysctl --system
For maximum security, we recommend only installing official security updates and security patches for your Linux distribution, as well as the RPMs specifically mentioned in this section.
Mount The etcd database on a separate volume

The etcd database should be on a separate disk to improve the stability of TOS Aurora and reduce latency. Moving the etcd database to a separate disk ensures that the kubernetes database has access to all the resources required to ensure an optimal TOS performance. This will require some down time as you are going to have to shut down TOS before separating the disks.
Install TOS Aurora
Deploy the Install File
1. On the target machine, create the directory /opt/tufin/data, if it does not exist already.
2. Transfer the TOS installation package (still in archive format .tgz) to the /opt/tufin/data directory.
3. Switch to the target directory
  [<ADMIN> ~]$ cd /opt/tufin/data
  
  cd /opt/tufin/data
4. Verify the integrity of the TOS installation package by entering the following commands and comparing the output with the checksum information.
5. Extract the TOS run file from the archive.
  [<ADMIN> ~]$ tar -xvzf tos-xxxx-xxxxxxxx-final-xxxx.run.tgz
  
  tar -xvzf tos-xxxx-xxxxxxxx-final-xxxx.run.tgz
6. Run the TOS Aurora run file.
  [<ADMIN> ~]$ sudo sh <runfile>
  
  sudo sh <runfile>
7. You must have permissions to execute TOS CLI commands. Grant permissions as shown below or allow use of sudo command.
  [<ADMIN> ~]# chmod +x /usr/local/bin/tos
  
  chmod +x /usr/local/bin/tos
Start the Install
1. Run the tmux command:
  [<ADMIN> ~]$ sudo tmux new-session -s install
  
  sudo tmux new-session -s install
2. Run the install command, replacing the parameters:
  - <SERVICE-CIDR> with the CIDR you want TOS Aurora to use for the Kubernetes service network, as described in Prerequisites
  - <MODULE-TYPE> with one of the following values:
    
    ST for SecureTrack only
    
    ST, SC for both SecureTrack and SecureChange
    
    RC for a remote collector
  - <LOAD> with the load-model parameter value received from your account team as described in Prerequisites.
    
    [<ADMIN> ~]$ sudo tos install --modules=<MODULE-TYPE> --primary-vip=<PRIMARY> --services-network=<SERVICE-CIDR> --pod-network=<PODS-CIDR> --load-model=<LOAD> -d
    
    sudo tos install --modules=<MODULE-TYPE> --primary-vip=<PRIMARY> --services-network=<SERVICE-CIDR> --pod-network=<PODS-CIDR> --load-model=<LOAD> -d
  Example:
  
  # sudo tos install --modules=ST,SC --primary-vip=external --services-network=10.10.10.0/24 --load-model=medium -d
  
  If you will be using UDP traffic and created alias IP ranges earlier, the command should be as follows:
  tos install -–modules=<MODULE-TYPE> --primary-vip=<LOAD BALANCER VIP> --syslog-vip=<SECOND ALIAS IP> tos install --services-network=10.10.10.0/24 --load-model=medium -d
3. The EULA is displayed. After reading, enter 'q' to exit the document and then enter 'y' to accept the EULA and continue until the command completes.
4. You can now safely exit the CLI tmux session:
  [<ADMIN> ~]$ exit
  
  exit
5. Go to the TOS Aurora login page by going to the URL of the load balancer DNS in your browser.
6. Log in with user=admin, password=admin. If a warning message is shown regarding the site security certificate, 'accept the risk' and continue to the site. You will be prompted to set a new password.
7. Check the TOS status.
  
  On the primary data node, check the TOS status.
  
  [<ADMIN> ~]$ tos status
  
  tos status
  
  In the output, check if the System Status is Ok and all the items listed under Components appear as Ok. If this is not the case, contact Tufin Support.
  
  Example output:
  [<ADMIN> ~]$ tos status [Mar 28 13:42:09] INFO Checking cluster health status TOS Aurora Tos Version: 24.2 (PRC1.1.0) System Status: "Ok" Cluster Status: Status: "Ok" Mode: "Single Node" Nodes Nodes: - ["node1"] Type: "Primary" Status: "Ok" Disk usage: - ["/opt"] Status: "Ok" Usage: 36% registry Expiration ETA: 819 days Status: "Ok" Infra Databases: - ["cassandra"] Status: "Ok" - ["kafka"] Status: "Ok" - ["mongodb"] Status: "Ok" - ["mongodb_sc"] Status: "Ok" - ["ongDb"] Status: "Ok" - ["postgres"] Status: "Ok" - ["postgres_sc"] Status: "Ok" Application Application Services Status OK Running services 54/54 Backup Storage: Location: "Local s3:http://minio.default.svc:9000/velerok8s/restic/default " Status: "Ok" Latest Backup: 2024-03-23 05:00:34 +0000 UTC
Post-Install Configuration

SSL Certificates

Secured connections to TOS Aurora require a valid SSL certificate. Such a certificate is generated during the installation. It is automatically renewed when it expires and also when upgrading to later versions of TOS Aurora. When connecting for the first time after certificate renewal, you will be prompted to accept the new certificate. You can also use your own CA signed certificate, but such certificates will not be renewed automatically.

SAN Certificates

For every FortiManager device you intend to monitor, add a SAN signed certificate.

License Activation

Relevant only for central clusters, skip for remote collectors.
- Tiered license: See Uploading License Files to TOS (Solution Tiers)
- Legacy license: Adding Licenses (Legacy Model)
After the license is activated, have all TOS users enable the automatic license mechanism in their browser. For more information, see Site Usage Monitoring.

Using Syslog for Accountability and More

You can use syslog to send accountability and other information from your devices to SecureTrack - see Sending Additional Information via Syslog. If you want to use this feature and you have installed TOS on-premise, you must also set up a Syslog VIP Address.

Adding Worker Nodes to Your Cluster

TOS Aurora is deployed as a single node Kubernetes cluster. See Multi-Node Cluster for more information about adding additional nodes.

Setting up External Backups

We recommend setting up backups on external storage.

Setting up Scheduled Backups

We recommend creating a backup policy as soon as possible.

DR (Disaster Recovery)

To setup TOS redundancy across sites, see Disaster Recovery.

TOS Monitoring

TOS Monitoring lets you monitor the status of the TOS cluster and its nodes by generating a notification whenever a change in status occurs, such as a node failing, or a usage threshold reached, such as CPU or disk usage. We recommend that you set up TOS notifications in TOS Monitoring (see TOS Monitoring).

Additional Configuration

A number of additional parameters can be set now or later e.g. session timeout and SNMP - see Configuring TOS.

SecureChange Settings

Relevant only for central clusters; skip for remote collectors.

If you have installed SecureChange:
1. Go into SecureChange by one the following means:
  - Sign in to TOS with the URL given previously and then select SecureChange from the app launcher.
  - Sign in directly to SecureChange by entering https://<IP>/tufinapps/securechange in the browser.
2. Configure the DNS.
  1. Go to Settings > Miscellaneous.
  2. Delete the default value that appears in the field Server DNS name. Enter a value for Server DNS name - the DNS server to use for links in email notifications. This can be an IP address in the format 11.22.33.44 or a FQDN in the format https://mydomain.com. The SecureChange DNS name is published by SecureChange so it can be accessed from external sources. For example, it is embedded in notification mails sent by SecureChange, which include a link to a ticket, such as an email notifying a handler assigned with a task, or informing a requester that the ticket has been successfully resolved.
3. Additional setup that can be done now or later:
  - Internal SSO Authentication. Internal SSO is enabled by default when TOS is installed, giving user access to all TOS components using the same credentials - SecureTrack, SecureChange, SecureApp, and extensions. When disabled, there is no connection between a SecureTrack user and SecureChange user with the same name.
  - Mail server connection
  - LDAP directory connection to use LDAP user accounts
  - Local users and user roles
  - Subsequent password changes can be made from the command line , see SecureChange Command Line Reference.
  - Change access to SecureTrack from SecureChange
    
    Go to Settings > SecureTrack:
    
    Change the default SecureTrack administrator. For SecureChange to access SecureTrack data, a SecureTrack administrator must be specified. By default this is the predefined user 'Admin' and everything will work fine if you leave it as it is. However, if you want a different user, create a new administrator and enter the user name. If you have already configured multi-domain management, this user can be either a super administrator or multi-domain administrator, depending on whether you want to restrict the administrator to selected domains.
    
    Remove link to SecureTrack . By default you can go from SecureChange to SecureTrack by selecting the SecureTrack link in the app launcher. If you want to remove this option, unmark the checkbox.
    
    Change connection check interval. The default value for the frequency of SecureChange testing connectivity to SecureTrack can be changed if desired.
    
    Click Test connection to verify that SecureChange has a connection to SecureTrack.
    
    Click Refresh license status. This will ensure that SecureTrack and SecureChange share the highest level of connectivity.
    
    Click Save.
