Server Security FAQ
Server security; It has already passed the level of "we bought hosting, we have SSL, that's enough". Especially in hotel & tourism and corporate structures, every data produced on the website, reservation infrastructure, PMS integration and CRM side is a potential target of attacks. This FAQ page; It collects the most frequently asked questions on topics such as server security, SSL certificate, firewall, DDoS protection, backup, logging and Next.js / security optimization in modern web infrastructures. The information here is for technical information purposes only; It does not guarantee a particular level of security. Professional security testing (pentest) and expert consultancy may be required, especially for critical systems.
Brief Summary (Overview)
This Server Security FAQ page; It summarizes why the "hosting + SSL is enough" approach is insufficient in the modern web world and which layers should be managed together to maintain data and service continuity in hotel & tourism / corporate structures. It offers a framework focused on "risk reduction" on topics such as SSL/TLS, firewall and WAF, DDoS protection, access management (IAM), backup-restore tests, logging-monitoring and security optimization in Next.js / modern distribution architectures (CDN, edge, serverless, env/secrets). The content is for informational purposes only; In critical systems, it should be supported by pentest and expert consultancy.

Server Security Overview (Common Questions)
What exactly is server security?⌄
Server security; It is the process of designing and managing the infrastructure on which the website, application, database and related services operate in a way that protects it against:
- •unauthorized access,
- •data leaks,
- •service interruptions (DDoS, etc.),
- •malicious code and configuration vulnerabilities
Why is server security critical “especially” for hotel and corporate sites?⌄
Because in these structures, the servers contain sensitive information such as:
- •reservation data (guest name, contact, date),
- •payment and billing information,
- •CRM and PMS integrations,
- •employee and supplier data
Are website security and server security the same thing?⌄
They partially overlap, but are not the same: <ul><li>Website security → application layer (forms, login screen,
Can server security be ensured with shared hosting?⌄
In shared hosting, the service provider offers some basic security; However, it may not fully meet the security and performance needs at hotel and corporate scale due to:
- •resource sharing,
- •limited access,
- •customization restrictions
Next.js / how does modern web infrastructures affect server security?⌄
When used correctly, it can provide:
- •less dynamic surfaces with static generation (SSG),
- •better distributed architecture with edge and CDN layers,
- •more limited and controlled backend points with serverless functions
Is it enough to leave server security only to the hosting company?⌄
Not quite. The hosting company:
- •takes some security measures at the infrastructure and network level,
- •application security,
- •access management,
- •IAM (user and key management),
- •log and monitoring,
- •backup scenario
Short Questions
What is server security and what does it do?
Server security; It protects your website, application and database against unauthorized access and attacks, allowing you to provide uninterrupted and secure service.
How can I make my hotel website more technically secure?
With an up-to-date infrastructure, SSL/HTTPS, strong password & 2FA, firewall, regular backup, up-to-date software and proper monitoring (logging & logging).
Is an SSL certificate really essential for SEO and trust?
Yes; HTTPS is now considered de facto mandatory for both browser security and Google ranking signals.
How do I protect against DDoS attacks?
You can become more resilient with CDN-based DDoS protection rate limiting, firewall rules and scalable infrastructure.
How should backup and logging be on the server side?
Backup: should be regular, automatic, in different locations and restoration tests should be performed. Logging: A structure should be established to store authorization and data access logs and security logs for reasonable periods of time.
Who is server security service suitable for?
Including hotel & tourism, corporate, e-commerce, SaaS products; It is important for every structure that works and processes data via the web and API.
Server Security Service Scope
What does your Server Security service technically cover?+
- •security audit of the current server and hosting structure,
- •SSL/HTTPS configuration control,
- •firewall rules and DDoS protection recommendations,
- •SSH/RDP access configuration,
- •user & key management (IAM) recommendations,
- •design of backup and restore scenarios,
- •logging and monitoring (monitoring/alerting) setup.
What is an SSL/TLS certificate and what does it cover?+
SSL/TLS certificate; It helps ensure:
- •data integrity,
- •confidentiality,
- •authentication
How does firewall work?+
Firewall; It is a filtering layer that controls access from:
- •which IPs,
- •which ports,
- •with which protocol
Why is it important to use WAF (Web Application Firewall)?+
WAF; Provides an additional layer of protection against common web attacks such as SQL Injection, XSS, brute-force. It does not completely eliminate vulnerabilities on the application side, but it can significantly reduce the risks caused by incorrect/unupdated code or 3rd party plugins.
How should the backup strategy be designed?+
- •backup frequency (daily, weekly, hourly),
- •how many versions will be stored,
- •in which environment (same server, separate server, cloud) they will be kept,
- •restore tests
What does the Server Security service mean for Next.js/modern web projects?+
- •Secure construction of hosting & deploy environment (Vercel, Netlify, your own server),
- •Management of environment variables (.env, secrets),
- •Protection of API routes,
- •correct cache/security settings in static/dynamic content distinction,
- •Secure integration with third party services (payment, auth, analytics).
Detailed Process & Operation
What do you analyze before starting a server security audit?+
- •which hosting/platform you are using,
- •operating system and versions,
- •which services (web server, db, redis, etc.) are open,
- •access methods (SSH, panel, RDP),
- •existing SSL certificates,
- •backup and logging practices,
- •application and integration structure (PMS, payment, APIs).
What are the “minimum security hardening” steps?+
For example:
- •up to date OS & packages,
- •root login disabled (for SSH),
- •key-based authentication / 2FA,
- •closing unnecessary ports and services,
- •simple rate limiting,
- •brute-force protection with fail2ban or similar tools,
- •basic WAF configuration.
How is the security approach of Cloud (AWS/Azure/GCP) vs classic hosting different?+
In cloud environments:
- •security groups,
- •IAM roles,
- •VPC,
- •managed WAF and DDoS services
How should access & user management be configured on the server?+
- •person-based accounts (instead of the common “admin”),
- •role-based authorization,
- •“least privilege” principle,
- •access on-off procedure during login/logout processes,
- •2FA or similar extra verifications for critical accounts.
How are logging and monitoring positioned in the process?+
- •access logs (web, SSH, panel),
- •error logs (application & server),
- •security event logs (WAF, firewall),
- •uptime and performance monitoring (CPU, RAM, disk, response time)
What is the relationship between server security and KVKK/personal data security?+
In systems where personal data is kept (PMS, web, CRM, DB); If server security is weak, the risk of data breach is high. KVKK technical measures are directly linked to server security (access control, logging, encryption, etc.). Lawyer for the legal framework; The security/IT team should work together for technical measures.
Performance, Security Risks & Core Issues
What are the most common risks when server security is weak?+
- •hacking (deface) of the web page,
- •inserting malicious code/redirects,
- •database leak,
- •falling into spam e-mail and IP blacklists,
- •complete site crash or inaccessibility.
How do DDoS attacks affect websites and how to prevent them?+
DDoS aims to consume the resources of your site or server by sending a large number of requests. As a result:
- •the site slows down or cannot respond,
- •real users cannot receive service.
- •CDN and DDoS protection services,
- •rate limiting,
- •firewall rules,
- •scalable infrastructure
What consequences does insufficient backup lead to?+
In case of an attack, incorrect deployment or human error:
- •all site content,
- •database,
- •configurations
Is wrong firewall/WAF configuration also a risk?+
Yes. Overly lax rules → open door for attacker; overly strict rules → problem for real users and integrations. For example, completely closing PMS integration ports may disrupt the connection; On the contrary, opening it to all IPs also creates risks.
Why is the “if I never update the server, it won't break” approach dangerous?+
Systems that are not updated:
- •remain with known security vulnerabilities,
- •become vulnerable to new attack sets,
- •some APIs and integrations begin to stop supporting over time.
Productive Search & Industry-Focused Server Security
What are the most critical layers in server security for hotels in Turkey?+
- •PMS and reservation servers,
- •website and booking engine hosting environment,
- •OTA integrated API endpoints,
- •CRM and e-mail marketing systems,
- •call center software and registration systems.
Where should server security be important for corporate companies?+
- •customer portals,
- •internal applications (intranet, ERP),
- •APIs and B2B integrations,
- •e-mail and file sharing systems.
Is a server located in Türkiye or a global cloud more secure?+
It's not just location; Configuration and management quality are decisive. Türkiye may be advantageous in terms of location, latency and some data regulations; Global cloud offers scalability and managed security services. In terms of KVKK/GDPR, you should evaluate the location preference with your lawyer.
Do security risks increase during peak season in tourism regions (Antalya, Bodrum, etc.)?+
During busy season, systems:
- •are used more,
- •the number of changes/deploys and campaigns increases,
- •operations team work more intensively.
What extra security points should be taken into consideration for sites operating in the foreign market?+
- •DDoS and bot protection for traffic from different countries,
- •security of payment provider integrations,
- •tests of multi-language/currency supported forms and payment flows,
- •clarity in which country the data is kept in international hosting/cloud scenarios (related to KVKK/GDPR).
Mini Server Security FAQ
Is it OK to install everything on a single server?+
It is possible in the short term for small projects; But as you scale, separating the application, database, cache and other services becomes more secure and manageable.
Does it make sense to run a critical system with shared hosting?+
Usually no. For critical data and integrations, more isolated and controllable environments (VPS, dedicated, cloud) should be preferred.
Is it still safe to send files via FTP?+
Classic FTP is not secure; You should use SFTP or FTPS and minimize manual file transfers with CI/CD pipelines if possible.
Does changing the SSH port from 22 alone work?+
Port switching can help reduce brute-force attempts, but it alone is not enough; key-based auth, fail2ban, firewall etc. should be supported by measures.
Is it safe to keep all admin passwords in an Excel?+
Not. It is much safer to use a secure password manager, manage access on a per-person basis, and not share passwords.
Why is it so risky to use the same password everywhere?+
When there is a leak somewhere, all your systems become vulnerable to attack with the same password. The most basic good practice is to use different passwords for different services and activate 2FA.
Should server security and application security be on the same team?+
Preferably, they should work in coordination; In some structures there may be the same team, in others there may be two separate teams, but constant communication and joint planning are essential.
Do I have to implement every security report as is?+
Prioritization is a must. Some risks may be critical and urgent, some may be medium/low level. However, instead of “ignoring it completely”, it is important to make conscious risk management.
Do security layers necessarily reduce performance?+
Some controls may introduce additional latency, but with the right configuration and scaling it can be kept at a level that the user will not notice. The security-performance balance must be established correctly.
Can I get the Server Security service only as “audit + report”?+
Yes; You can examine your current structure, obtain a technical report containing your risks and improvement suggestions, and carry out the implementation part with your own IT team or another partner.
