Squid Proxy (Hardened) on Amazon Linux 2023
This product has charges associated with it for image hardening, maintenance, and support. Squid caching proxy on Amazon Linux 2023, security-hardened for production: minimal package set, SSH key-only access, IMDSv2-only, and continuously patched images.
Why this image
- Security-hardened at build time: minimal packages, key-only SSH, IMDSv2-only, proxy port firewalled to trusted CIDRs.
- Continuously patched: rebuilt, vulnerability-scanned, and republished on a regular cadence.
- Production-ready: systemd-managed Squid; tune ACLs and cache in /etc/squid/squid.conf.
About
Squid Proxy (Hardened) on Amazon Linux 2023 is a production-ready, security-hardened image of the Squid caching and forwarding web proxy, maintained and supported by Derek Coleman & Associates Incorporated.
This is repackaged open-source software. Squid is developed by the Squid Project and is distributed under the GNU General Public License v2 or later. This product bundles unmodified upstream Squid on a hardened Amazon Linux 2023 base; the charges associated with this listing are for image hardening, continuous patching, vulnerability scanning, and business-day support - not for the underlying open-source software, which remains free.
Hardening baseline: minimal package footprint, SSH key-only access (password authentication disabled), IMDSv2 enforced, and a deny-all default proxy policy (Squid ships denying all client access; defining your ACLs in /etc/squid/squid.conf and opening TCP 3128 to trusted CIDRs is a deliberate customer configuration step, so the instance cannot be abused as an open proxy). Images are rebuilt, scanned for HIGH and CRITICAL vulnerabilities, and republished on a regular cadence so that new launches start current. Manage the service with systemd: sudo systemctl restart squid.

Getting started
Launch from AWS Marketplace (1-Click or EC2 console). Connect via SSH: ssh -i <key> ec2-user@<public-ip>. Edit /etc/squid/squid.conf to set your ACLs (Squid denies all by default), then: sudo systemctl restart squid, and open TCP 3128 to trusted CIDRs only. Root login is disabled; use sudo. There are no passwords anywhere in this product.
