Apache Webserver mit Loadbalancer
2 Tage left
Ich betreibe einen Linux-Server unter SLES 15, hinter dem bereits ein Loadbalancer vorgeschaltet ist. Für diesen Server möchte ich eine saubere Apache-Konfiguration, die den Traffic korrekt vom Loadbalancer übernimmt und anschließend zuverlässig an die gehosteten Anwendungen weiterleitet. Dein Auftrag umfasst: • Installation / Prüfung aller benötigten Apache-Pakete auf SLES 15 • Erstellung einer übersichtlichen inklusive aller benötigten Module • Einbindung der vorhandenen Loadbalancer-Header (X-Forwarded-For usw.), damit Logs und SSL-Terminations richtig ausgewertet werden können • Absicherung des Setups (Hardening, sinnvolle Defaults, Firewall-Checks) • Dokumentation jedes Schritts, sodass ich Ä...

Patch Compromised Ubuntu VPS Security
6 Tage left
My provider has suspended my Ubuntu VPS after flagging a hack on the web-server layer (Apache/Nginx, exact stack is in the incident report I will share once we start). At the moment I have zero hardening in place—no firewall rules, no SSL, nothing—so the attacker clearly found an easy way in. I do have a recent full backup, so you can work safely and roll back if needed. Your mission is to identify the entry point, remove any malicious code or files, close the vulnerability, and leave the server in a state that convinces the host to lift the ban. You are welcome to use tools such as fail2ban, UFW/iptables, ClamAV, rkhunter, ModSecurity, or any other utilities you normally rely on. Deliverables • Clean, uncompromised web root and services reinstated • Detailed ...

Harden Lenovo T480 with Debian
4 Tage left
Verifiziert
I have a Lenovo ThinkPad T480 waiting for a fresh, security-first Debian installation. The goal is a fully hardened, privacy-respecting daily-driver that ships with BOTH Mozilla Firefox and Brave, each pre-tuned for strong tracking-protection and fingerprint-resistance. This is an ADVANCED hardening job. Beyond the base install I’ll need full-disk LUKS2 encryption, secure boot/Libreboot if the hardware permits, locked-down BIOS settings, kernel and sysctl tweaks, AppArmor (or comparable MAC), DNS proxy with encrypted queries, and a firewall configured to best practice levels. I did not select a specific firewall in the form, so feel free to recommend whether UFW, iptables or firewalld is the right fit for an always-on laptop that roams between trusted and untrusted networks. Delive...

Secure Dual-Site UDM Pro Connection
3 Tage left
Verifiziert
I operate two offices and I purchased two UniFi UDM Pro, and I want them linked so that staff can reach internal resources from either location as if they were on the same LAN or to work remotely (VPN access). Nothing is in place yet, so the full security stack must be designed and deployed from scratch. Scope of work • Build and test a site-to-site VPN between the two UDM Pros for seamless remote access. • Create granular firewall rules that allow only the traffic we specify while blocking everything else. • Enable and tune UniFi’s intrusion-detection/prevention features to catch unwanted activity without flooding us with false alarms. • Document every setting—screenshots or exported configs—so I can replicate or restore the setup if needed. ...

Sophos & Fortinet Firewall Assistance
2 Tage left
My network edge relies on a Sophos XG appliance and a Fortinet FortiGate unit. Both devices are in production, but their current configuration is a mix of legacy rules and quick fixes that now interfere with performance and security. I want a seasoned firewall engineer to step in, examine every setting, correct what is wrong, and design a clean, least-privilege rule base. Scope of work • Configuration – back up the existing setups, remove or refine redundant rules, and align all interfaces, NAT, VPN, IPS and logging options with best-practice guidelines for Sophos SFOS and FortiOS. • Troubleshooting – identify and eliminate the intermittent drops we see on site-to-site VPN and outbound web traffic. Validation must include live traffic tests and log review. &bul...

Cloudflare Guru needed. Too many bots on the website
1 Tag left
Verifiziert
I run a Canadian real-estate search engine that must stay lightning-fast for genuine home-hunters while remaining fully crawlable by Google, Bing and other reputable AI/search bots. Right now Cloudflare shows ±100 k daily hits from malicious, spam and scraper bots; that traffic spikes the servers, ruins bounce-rate metrics and occasionally knocks the site offline. I have already: • Placed the site on Cloudflare, • Allowed full, captcha-free access for visitors inside Canada, • Forced most other countries through a captcha, • Experimented with firewall rules, IP and UA blocking. Unfortunately, Google’s crawler activity drops whenever the shield becomes too strict, so I’m looking for an expert who can strike the sweet spot: block malicious...
