Centurion Intelligence Consulting Agency Information Security Standard
Debian Live Build Generator for hardened live environment and CISS Debian Installer
Master Version: 8.02
Build: V8.03.127.2025.06.02

+

This shell wrapper automates the creation of a Debian Bookworm live ISO hardened according to the latest best practices in server and service security. It integrates into your build pipeline to deliver an isolated, robust environment suitable for cloud deployment or unattended installations via the forthcoming CISS.debian.installer. Find here more information to download the latest ISO available. To download the latest public available CISS.debian.live.builder ISO, see: tba.

+ +

1.1. Preliminary Remarks

+

1.1.1. HSM

+

Please note that all my signing keys are stored in an HSM and that the signing environment is air-gapped. The next step is to move to a room-gapped environment. ^^

+

1.1.2. HSTS and DNSSEC

+

Please note that coresecret.dev is included in the (HSTS Preload List) and always serves the headers:

+
add_header Expect-CT                 "max-age=86400, enforce"                       always;
+add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;
+

Additionally, the entire zone is dual-signed with DNSSEC. See the current DNSSEC status at DNSSEC Audit Report

+

1.2. Immutable Source-of-Truth System

+

This live ISO establishes a secure, fully deterministic, integrity self-verifying boot environment based entirely on static source-code definitions. All configurations, system components, and installation routines are embedded during build time and locked for runtime immutability. This ensures that the live environment functions as a trusted Source of Truth — not only for boot-time operations, but for deploying entire systems in a secure and reproducible way.

+

Once booted, the environment optionally launches a fully scripted installer, via the forthcoming CISS.debian.installer, yet to deploy, that provisions the target system (the hardware the DVD is running on). The installer pulls no external dependencies besides of the necessary Debian debootstrap and Debian Packages and never exposes the target system in a not secure manner to the internet during installation. It operates strictly from within the verified image content, providing fully secured provisioning. Combined with checksum verification, activated by default, at boot and strict firewall defaults, this architecture guarantees that what is executed has not been tampered with and corresponds exactly to the intended source definition.

+

An even more secure deployment variant — an unattended and headless version — can be built without any active network interface or shell-access, also via the forthcoming CISS.debian.installer. Such a version performs all verification steps autonomously, provisions the target device from embedded source artifacts, and reboots into a fully encrypted system image. The system then awaits the decryption passphrase input via an embedded Dropbear SSH server (SSH PubKey only) in the initramfs, exposing no ports without cryptographic hardened access, while also the /boot partition could be encrypted via the built-in support of grub2 (2.12-1~bpo12+1).

+

This approach provides a fully reproducible, audit-friendly, and tamper-resistant provisioning workflow rooted entirely in source-defined infrastructure logic.

+

After build and configuration, the following audit reports can be generated:

2. Features & Rationale

+

Below is a breakdown of each hardening component, with a summary of why each is critical to your security posture.

+

2.1. Kernel Hardening

+

2.1.1. Boot Parameters

+ +

2.1.2. CPU Vulnerability Mitigations

+ +

2.1.3. Kernel Self-Protection

+ +

2.1.4. Local Kernel Hardening

+ +
###########################################################################################
+# Globals: Wrapper for loading CISS.2025 hardened Kernel Parameters
+# Arguments:
+#  none
+###########################################################################################
+# shellcheck disable=SC2317
+sysp() {
+  sysctl -p /etc/sysctl.d/99_local.hardened
+  # sleep 1
+  sysctl -a | grep -E 'kernel|vm|net' > /var/log/sysctl_check"$(date +"%Y-%m-%d_%H:%M:%S")".log
+}
+ +

Warning Once applied, some hardening settings cannot be undone via sysctl without a reboot, and dynamic module loading remains disabled until the next boot. Automatic enforcement at startup is therefore omitted by design—run sysp() manually and plan a reboot to apply or revert these controls.

+

2.2. Module Blacklisting

+ +

2.3. Network Hardening

+ +

2.4. Core Dump & Kernel Hardening

+ +

2.5. Entropy Collection Improvements

+ +

2.6. Permissions & Authentication

+ +

2.7. High-Security Baseline (Lynis Audit)

+ +

2.8. SSH Tunnel & Access Security

+ +

2.9. UFW Hardening

+ +

2.10. Fail2Ban Enhancements

+ +

2.11. NTPsec & Chrony

+ +

3. Script Features & Rationale

+

3.1. Input Validation & Security

+ +

3.2. Debug Mode with Detailed Logging

+ +

3.3. Secure Debug Logging

+ +

3.4. Secure Password Handling

+ +

3.5. Variable Declaration & Validation

+ +

3.6. Pure Bash Implementation

1. CISS.debian.live.builder

+

Centurion Intelligence Consulting Agency Information Security Standard
Debian Live Build Generator for hardened live environment and CISS Debian Installer
Master Version: 8.02
Build: V8.03.127.2025.06.02

+

This shell wrapper automates the creation of a Debian Bookworm live ISO hardened according to the latest best practices in server and service security. It integrates into your build pipeline to deliver an isolated, robust environment suitable for cloud deployment or unattended installations via the forthcoming CISS.debian.installer. Find here more information to download the latest ISO available. To download the latest public available CISS.debian.live.builder ISO, see: tba.

+ +

1.1. Preliminary Remarks

+

1.1.1. HSM

+

Please note that all my signing keys are stored in an HSM and that the signing environment is air-gapped. The next step is to move to a room-gapped environment. ^^

+

1.1.2. HSTS and DNSSEC

+

Please note that coresecret.dev is included in the (HSTS Preload List) and always serves the headers:

+
add_header Expect-CT                 "max-age=86400, enforce"                       always;
+add_header Strict-Transport-Security "max-age=63072000; includeSubDomains; preload" always;
+

Additionally, the entire zone is dual-signed with DNSSEC. See the current DNSSEC status at DNSSEC Audit Report

+

1.2. Immutable Source-of-Truth System

+

This live ISO establishes a secure, fully deterministic, integrity self-verifying boot environment based entirely on static source-code definitions. All configurations, system components, and installation routines are embedded during build time and locked for runtime immutability. This ensures that the live environment functions as a trusted Source of Truth — not only for boot-time operations, but for deploying entire systems in a secure and reproducible way.

+

Once booted, the environment optionally launches a fully scripted installer, via the forthcoming CISS.debian.installer, yet to deploy, that provisions the target system (the hardware the DVD is running on). The installer pulls no external dependencies besides of the necessary Debian debootstrap and Debian Packages and never exposes the target system in a not secure manner to the internet during installation. It operates strictly from within the verified image content, providing fully secured provisioning. Combined with checksum verification, activated by default, at boot and strict firewall defaults, this architecture guarantees that what is executed has not been tampered with and corresponds exactly to the intended source definition.

+

An even more secure deployment variant — an unattended and headless version — can be built without any active network interface or shell-access, also via the forthcoming CISS.debian.installer. Such a version performs all verification steps autonomously, provisions the target device from embedded source artifacts, and reboots into a fully encrypted system image. The system then awaits the decryption passphrase input via an embedded Dropbear SSH server (SSH PubKey only) in the initramfs, exposing no ports without cryptographic hardened access, while also the /boot partition could be encrypted via the built-in support of grub2 (2.12-1~bpo12+1).

+

This approach provides a fully reproducible, audit-friendly, and tamper-resistant provisioning workflow rooted entirely in source-defined infrastructure logic.

+

After build and configuration, the following audit reports can be generated:

2. Features & Rationale

+

Below is a breakdown of each hardening component, with a summary of why each is critical to your security posture.

+

2.1. Kernel Hardening

+

2.1.1. Boot Parameters

+ +

2.1.2. CPU Vulnerability Mitigations

+ +

2.1.3. Kernel Self-Protection

+ +

2.1.4. Local Kernel Hardening

+ +
###########################################################################################
+# Globals: Wrapper for loading CISS.2025 hardened Kernel Parameters
+# Arguments:
+#  none
+###########################################################################################
+# shellcheck disable=SC2317
+sysp() {
+  sysctl -p /etc/sysctl.d/99_local.hardened
+  # sleep 1
+  sysctl -a | grep -E 'kernel|vm|net' > /var/log/sysctl_check"$(date +"%Y-%m-%d_%H:%M:%S")".log
+}
+ +

Warning Once applied, some hardening settings cannot be undone via sysctl without a reboot, and dynamic module loading remains disabled until the next boot. Automatic enforcement at startup is therefore omitted by design—run sysp() manually and plan a reboot to apply or revert these controls.

+

2.2. Module Blacklisting

+ +

2.3. Network Hardening

+ +

2.4. Core Dump & Kernel Hardening

+ +

2.5. Entropy Collection Improvements

+ +

2.6. Permissions & Authentication

+ +

2.7. High-Security Baseline (Lynis Audit)

+ +

2.8. SSH Tunnel & Access Security

+ +

2.9. UFW Hardening

+ +

2.10. Fail2Ban Enhancements

+ +

2.11. NTPsec & Chrony

+ +

3. Script Features & Rationale

+

3.1. Input Validation & Security

+ +

3.2. Debug Mode with Detailed Logging

+ +

3.3. Secure Debug Logging

+ +

3.4. Secure Password Handling

+ +

3.5. Variable Declaration & Validation

+ +

3.6. Pure Bash Implementation

+ +

3.7. Bash Error Handling

+  Suggestions (5):
+  ----------------------------
+  * Consider hardening system services [BOOT-5264]
+    - Details  : Run '/usr/bin/systemd-analyze security SERVICE' for each service
+    - Related resources
+      * Article: Systemd features to secure service files: https://linux-audit.com/systemd/systemd-features-to-secure-units-and-services/
+      * Website: https://cisofy.com/lynis/controls/BOOT-5264/
+
+  * To decrease the impact of a full /home file system, place /home on a separate partition [FILE-6310]
+    - Related resources
+      * Website: https://cisofy.com/lynis/controls/FILE-6310/
+
+  * To decrease the impact of a full /var file system, place /var on a separate partition [FILE-6310]
+    - Related resources
+      * Website: https://cisofy.com/lynis/controls/FILE-6310/
+
+  * Check iptables rules to see which rules are currently not used [FIRE-4513]
+    - Related resources
+      * Website: https://cisofy.com/lynis/controls/FIRE-4513/
+
+  * Enable logging to an external logging host for archiving purposes and additional protection [LOGG-2154]
+    - Related resources
+      * Website: https://cisofy.com/lynis/controls/LOGG-2154/
+
+  Follow-up:
+  ----------------------------
+  - Show details of a test (lynis show details TEST-ID)
+  - Check the logfile for all details (less /var/log/lynis.log)
+  - Read security controls texts (https://cisofy.com)
+  - Use --upload to upload data to central system (Lynis Enterprise users)

2. Coding Style

+

2.1. PR

+

You'd make the life of the maintainers easier if you submit only one patch with one functional change per PR.

+

2.2 Documentation

+

Some people really read that ! New features would need to be documented in the appropriate section in usage() and in ~/docs/DOCUMENTATION.md.

+

2.3. Coding

+

2.3.1. Shell / bash

+

Bash is actually quite powerful—not only with respect to sockets. It's not as mighty as perl or python, but there are a lot of neat features. Here's how you make use of them. Besides those short hints here, there's a wealth of information there.

+ +

2.3.2. Shell specific

+ +

2.3.3. Variables

+ +

3. Misc
