Physical Security Lapses Expose Sensitive Servers
Your cybersecurity is only as strong as the physical locks on your servers - and a recent case where a server-room lock proved laughably easy to bypass is a stark reminder of this often-overlooked vulnerability. Leaving sensitive servers exposed is like leaving a car with cash in the console unlocked - it's an open invitation…

Server Security Checklist — Essential Hardening Guide
Securing your servers isn’t optional — it’s your first line of defense against data breaches, ransomware, insider threats, and lateral movement. Use this checklist as a baseline for Linux, Windows, cloud, hybrid, or on-prem servers.
⸻
🔧 1. System & OS Hardening
• Keep OS & packages updated (apply security patches frequently).
• Remove / disable unused services & software.
• Enforce secure boot + BIOS/UEFI passwords.
• Disable auto-login and guest accounts.
• Use minimal OS images only (reduce attack surface).⸻
🔐 2. Access Control
• Enforce strong passwords & MFA everywhere.
• Use RBAC & least privilege access.
• Disable root/Administrator login over SSH/RDP.
• Rotate credentials & keys regularly.
• Implement just-in-time access for privileged users.⸻
🌐 3. Network Security
• Restrict inbound/outbound traffic via firewalls.
• Segment critical servers from general LANs/VLANs.
• Disable unused ports & protocols.
• Enable DoS/DDoS protection.
• Apply zero-trust network principles.⸻
🔑 4. Secure Remote Access
• Use SSH key-based authentication (disable password login).
• Enforce VPN for admin access.
• Log & monitor all remote access sessions.
• Disable legacy protocols (Telnet, FTP, SMBv1).
• Require bastion/jump host for critical access.⸻
📊 5. Logging & Monitoring
• Enable centralized logging (syslog / SIEM).
• Track failed login attempts & anomalies.
• Configure alerts for privilege escalation or config changes.
• Monitor log tampering.
• Retain logs securely for audits & forensics.⸻
🔒 6. Data Protection
• Encrypt data at rest (LUKS, BitLocker, etc.).
• Encrypt data in transit (TLS 1.2+).
• Strict database access policies.
• Regular, offline, immutable backups.
• Test restore procedures (don’t assume backups work).⸻
🔁 7. Application & Patch Management
• Keep middleware, frameworks, and apps patched.
• Delete default credentials & sample files.
• Enable code signing for software packages.
• Use secure coding practices (OWASP Top 10).
• Implement dependency scanning (Snyk, Trivy, etc.).⸻
🛡️ 8. Malware & Intrusion Defense
• Deploy EDR/AV on endpoints.
• Enable IDS/IPS at network edge.
• Automatic vulnerability scans (schedule weekly/monthly).
• Monitor persistence techniques (cron, startup scripts).
• Block known malicious IP ranges & TLDs.⸻
🏢 9. Physical & Cloud Security
• Restrict physical access to server racks/rooms.
• Enable provider security tools (AWS Security Groups, Azure NSG, IAM).
• Harden cloud images (CIS benchmarks).
• Review cloud logging & audit trails regularly.
• Disable unused cloud API keys / roles.⸻
📜 10. Policy & Compliance
• Use CIS / NIST / ISO-27001 benchmarks.
• Track & document every access change.
• Force annual access reviews & key rotation.
• Perform regular security training for admins.
• Maintain disaster recovery & incident plans.⸻
➕ Additional 5 Critical Controls (Advanced Hardening)
🧠 11. Privileged Access Management (PAM)
• Use jump hosts & session recording.
• Just-In-Time access for admins.
• Store keys in secure vaults (HashiCorp Vault, CyberArk).🚨 12. Real-Time Threat Detection
• Use behavioral analytics → UEBA/XDR.
• AI-based anomaly detection recommended.
• Block suspicious IPs automatically.🧪 13. Red Team & Pentesting
• Run regular internal pentests.
• Validate configuration weaknesses.
• Simulate phishing + lateral movement scenarios.🧱 14. Container / VM Isolation
• Use AppArmor, SELinux, Seccomp profiles.
• Limit Docker socket access & root containers.
• Scan images before deployment.📦 15. Automated Configuration Management
• Use IaC (Terraform, Ansible, Puppet) for repeatable and secure builds.
• Detect drift using compliance scanning.
• Version control all infrastructure.⸻

20,000 failed SSH logins in 2 days.
On a server hosting only a static webpage.Recently, I was checking logs on a VM that I own. It has no backend, no database.
Just a static webpage served by NGINX.Yet, I found 20k failed SSH login attempts.
A VM becomes a target the moment it’s online.
Fortunately, password logins were disabled. Here is my new server security routine (non-root user, SSH auth, fail2ban etc.):

🐦🥱 Ah yes, because nothing says cutting-edge anthropology like a 400 Bad Request error. Clearly, ancient Patagonian server security was way ahead of its time, blocking all access to any meaningful information. If only their hunter-gatherers had a helpline for their own glitches. 🙄

🔧 You may not notice, but to improve server security, we’ve decided to disable IPv6. Since our provider, OVHCloud, doesn’t offer DDoS protection or edge firewall for IPv6, we made this decision to ensure a better and more stable service.

Heads up for any server admins (especially cPanel ones):
Way To The Web Ltd (aka ConfigServer) who provide the very useful and handy ConfigServer Firewall (csf) and many other products are closing down at the end of August - no updates/downloads will be available from that date.

Недавно была обнаружена критическая уязвимость в программном обеспечении MegaRAC Baseboard Management Controller (BMC) от American Megatrends International (AMI), используемом в серверах таких производителей, как HPE, Asus и ASRock.
**Описание уязвимости:**
Уязвимость, получившая идентификатор CVE-2024-54085, позволяет удалённым неаутентифицированным злоумышленникам получить полный контроль над уязвимыми серверами. Атака может быть осуществлена через интерфейсы удалённого управления, такие как Redfish, и не требует сложных технических навыков или взаимодействия с пользователем.
**Возможные последствия эксплуатации:**
- Удалённое управление сервером, включая развёртывание вредоносного ПО или программ-вымогателей.
- Модификация прошивки, что может привести к повреждению компонентов материнской платы, таких как BMC или BIOS/UEFI.
- Физическое повреждение сервера, например, через создание условий перенапряжения или постоянные циклы перезагрузки, которые невозможно остановить без физического вмешательства.
**Рекомендации:**
Администраторам и владельцам серверов рекомендуется:
- Ограничить доступ к интерфейсам удалённого управления (например, Redfish) только доверенным сетям.
- Регулярно обновлять прошивки BMC до последних версий, содержащих исправления безопасности.
- Мониторить сетевой трафик на предмет подозрительной активности, связанной с BMC.

**Ограничение доступа** – Отключить удалённые интерфейсы управления (Redfish, IPMI) от внешних сетей и ограничить доступ только доверенным IP-адресам.
**Мониторинг активности** – Настроить логирование и мониторинг попыток несанкционированного доступа к BMC.
**Сегментирование сети** – Разместить BMC в отдельной изолированной сети, недоступной из интернета.
**Использование VPN** – Если удалённый доступ к BMC необходим, использовать безопасное подключение через VPN.
**Жёсткая аутентификация** – Включить двухфакторную аутентификацию (2FA) и сменить стандартные пароли.
**Аудит уязвимых устройств** – Проверить список серверов в инфраструктуре, использующих MegaRAC BMC, и оценить их уязвимость.

Does anyone have any handy guides for properly locking down a linux server used for hosting? I've been doing an okay job with mine but I think if anyone has a good guide about how to make sure I didn't miss anything, that would be nice!
It's primarily for web hosting, including fedi, and sometimes as a fallback matrix/chat thing. Boosts appreciated!
