Over deze dienst
Note: I was away on vacation for some time, which caused my Fiverr activity and performance metrics to drop temporarily. As a result, my seller level was reduced from Level 2 to Level 0. Please contact me though my response time is bad.
Your servers face constant scanning by automated bots the moment they come online, with these bots capable of automatically probing vulnerabilities. This capability makes it easy for hackers to identify potential targets for attack.
Failure to address this issue leaves your servers vulnerable to being brought down by hackers or, even worse, allows them to steal valuable customer data.
To mitigate these risks, I propose the following actions:
- Conduct a thorough examination of common open ports and, if necessary, switch them to alternative ports.
- Implement a firewall and enhance port blocking measures.
- Establish an SSH Key Pair system to enable password-less login.
- Perform software updates on your servers to ensure all vulnerabilities are patched.
- Close any unused ports to minimize potential entry points.
- Monitor log files for any signs of unusual activity.
By implementing these measures, I will

Veelgestelde vragen
What do you need to start working on my server?
I will need temporary SSH access (root or sudo) and, if Cloudflare setup is required, access to your Cloudflare account. You may also send me a temporary password or I can guide you in generating an SSH key for secure access.
Will my website or server experience downtime?
No. All changes are done carefully to avoid service interruption. If a change requires a restart (e.g., Nginx/Apache/PHP), I will notify you before proceeding.
Is SSH key-pair login safe? Why do you recommend it?
Yes. SSH key authentication is significantly safer than passwords. It prevents brute-force attacks and ensures only approved devices can access your server.
What firewall will you configure?
Yes. I will configure Cloudflare security settings to block bots, enable DDoS protection, apply rate-limiting (optional), and strengthen your DNS security.
Can you detect if my server has already been attacked?
Yes. I examine server logs for suspicious activity, brute-force attempts, bot scans, and unauthorized access patterns. If issues are found, I will notify you and propose fixes.
Do you install Fail2Ban? What does it do?
Yes, if requested. Fail2Ban automatically bans abusive IPs that trigger repeated failed logins or bot-like behavior. It significantly reduces attack attempts.
Will you update my server software?
Yes. Security updates are included to ensure known vulnerabilities are patched at the OS and service level.
Will my applications be affected by the port changes?
No. Before closing or modifying ports, I check their usage to avoid stopping any required services. Unused ports are closed safely.
I’m not technical. Can you handle everything for me?
Absolutely. You don’t need technical knowledge — I take care of the complete setup, configuration, and hardening. I will also provide explanations if you want to understand what was done.
