Question 12

two-factor authentication (2FA) and how do I enable it for my hosting account নত্রগা কদাই?

Accepted Answer

Two-factor authentication (2FA) adds a second verification step beyond your password — typically a time-based one-time password (TOTP) from an authenticator app (Google Authenticator, Authy, Microsoft Authenticator). Even if someone steals your password, they cannot log in without the rotating 6-digit code from your phone. Enable 2FA for Connect Quest account at connectquest.co.in account settings. Enable for cPanel: cPanel > Security > Two-Factor Authentication, scan QR code with your authenticator app, verify with a code. Enable for WHM: similar process under Security Center.

Question 13

a DDoS attack and how does Connect Quest protect against it নত্রগা কদাই?

Accepted Answer

A DDoS (Distributed Denial of Service) attack floods your server with traffic from thousands of compromised computers (botnet), overwhelming bandwidth and server resources until legitimate visitors cannot access your site. Common types: volumetric (bandwidth exhaustion), protocol attacks (SYN flood), and application layer (HTTP flood targeting WordPress login). Connect Quest includes network-level DDoS mitigation on all plans — scrubbing centers detect and filter malicious traffic before it reaches your server. For WordPress-specific protection: install Cloudflare free tier (rate limiting, bot...

Question 15

Core Web Vitals and how do I improve my Google performance scores নত্রগা কদাই?

Accepted Answer

Core Web Vitals are Google's user experience metrics that directly affect search rankings. Three primary metrics: LCP (Largest Contentful Paint) — time for main content to load (target: under 2.5 seconds), FID/INP (Interaction to Next Paint) — time for page to respond to user input (target: under 200ms), CLS (Cumulative Layout Shift) — visual stability as page loads (target: under 0.1). Measure with: Google PageSpeed Insights (free, real-world and lab data), Google Search Console > Core Web Vitals report.

Question 16

SSH key authentication and how do I set it up on a VPS নত্রগা কদাই?

Accepted Answer

SSH key authentication uses asymmetric cryptography instead of passwords — your private key (stays on your machine) proves identity to the server which holds your public key. Brute-force attacks are mathematically infeasible against proper SSH keys (4096-bit RSA or Ed25519). Setup process: 1) Generate key pair on your local machine: ssh-keygen -t ed25519 -C "your-email@example.com". 2) Copy public key to VPS: ssh-copy-id -i ~/.ssh/id_ed25519.pub root@your-vps-ip. 3) Test key login: ssh -i ~/.ssh/id_ed25519 root@your-vps-ip. 4) After confirming key login works, disable password authentication: ...

malware and how do I clean a hacked WordPress site নত্রগা কদাই?

Accepted Answer

WordPress malware includes PHP backdoors, redirects to spam sites, SEO spam (injected hidden links), cryptominers, and phishing pages. Signs of infection: Google Search Console shows security warnings, site redirects visitors to unknown sites, hosting account suspended, or antivirus flags your site. Cleaning process: 1) Take your site offline temporarily (maintenance mode). 2) Run Wordfence scan: Wordfence > Scan > Start Scan — quarantine or delete flagged files. 3) Use fresh WordPress core: download clean copy, replace wp-admin and wp-includes (keep wp-content and wp-config.php). 4) Check wp-...

Question 19

rate limiting and how does it protect my API and website নত্রগা কদাই?

Accepted Answer

Rate limiting restricts how many requests a client can make to your server within a time window, preventing abuse: brute-force login attacks, API scraping, DDoS attempts, and accidental infinite loops. Implementation layers: 1) Cloudflare rate limiting (easiest): Dashboard > Security > WAF > Rate Limiting Rules — block IPs making over 100 requests/minute to wp-login.php. 2) Nginx rate limiting: limit_req_zone $binary_remote_addr zone=login:10m rate=5r/m; in http block, then limit_req zone=login burst=3; in location blocks for login pages. 3) Application-level (Node.js): use express-rate-limit ...

Question 20

Content Security Policy (CSP) and how do I implement it নত্রগা কদাই?

Accepted Answer

Content Security Policy (CSP) is an HTTP security header that tells browsers exactly which resources (scripts, styles, images, frames) are allowed to load on your page, preventing Cross-Site Scripting (XSS) attacks. Without CSP, if an attacker injects a script tag, it executes. With CSP, the browser only executes scripts from whitelisted sources. Add CSP header in .htaccess: Header set Content-Security-Policy "default-src 'self'; script-src 'self' 'unsafe-inline' https://www.google-analytics.com https://cdn.jsdelivr.net; style-src 'self' 'unsafe-inline'; img-src 'self' data: https:; font-src '...

Question 21

hotlink protection and how do I enable it নত্রগা কদাই?

Accepted Answer

Hotlinking occurs when another website embeds your images directly using your server's URL (e.g., <img src="https://yoursite.com/image.jpg"> on theirsite.com). This consumes your bandwidth and server resources while benefiting them at your cost. Hotlink protection blocks requests for your images from other domains. Enable in Connect Quest cPanel: Security > Hotlink Protection > Enable. Select file types to protect (jpg, jpeg, png, gif, webp, mp4). Optionally redirect hotlinked images to a warning image. Via .htaccess: RewriteEngine On, RewriteCond %{HTTP_REFERER} !^$, RewriteCond %{HTTP_REFERE...

Question 24

a Web Application Firewall (WAF) and how does ModSecurity work নত্রগা কদাই?

Accepted Answer

A Web Application Firewall (WAF) filters HTTP/HTTPS traffic between the internet and a web application, blocking requests that match attack patterns (SQL injection, XSS, directory traversal) before they reach the application code.

DETAILED EXPLANATION:
WAFs operate at Layer 7 (Application Layer) of the OSI model — unlike network firewalls that filter at Layer 3/4 (IP/TCP). A WAF inspects the full HTTP request: URL, headers, GET/POST parameters, cookies, and request body.

ModSecurity is the industry-standard open-source WAF engine that integrates with Apache, Nginx, and LiteSpeed. It uses rul...

Question 25

DDoS protection and how does Connect Quest implement it নত্রগা কদাই?

Accepted Answer

DDoS (Distributed Denial of Service) protection identifies and filters malicious flood traffic before it reaches your server, allowing legitimate traffic through while absorbing attack volumes that would otherwise take your service offline.

DETAILED EXPLANATION:
DDoS attacks work by overwhelming a server's bandwidth, connection table, or CPU with fake requests. Types:
- Volumetric: UDP floods, ICMP floods (100+ Gbps) — exhaust bandwidth
- Protocol: SYN floods, fragmented packet attacks — exhaust connection tables
- Application Layer (Layer 7): HTTP floods, Slowloris — exhaust application reso...

Question 26

SSL/TLS and what is the difference between DV, OV, and EV certificates নত্রগা কদাই?

Accepted Answer

SSL (Secure Sockets Layer) / TLS (Transport Layer Security) are cryptographic protocols that encrypt data between a client browser and a web server. DV, OV, and EV refer to the validation level — how thoroughly the Certificate Authority verified the certificate requestor's identity.

DETAILED EXPLANATION:
All three types provide identical encryption strength (256-bit AES). The difference is in who is verified:

DV (Domain Validation): CA only verifies you control the domain (via DNS record or file upload). Issued in minutes. Shows padlock in browser. Used by 90%+ of websites including Let's En...

Question 27

Fail2ban and how do I configure it to protect my server নত্রগা কদাই?

Accepted Answer

Fail2ban is an intrusion prevention software that monitors server log files and temporarily or permanently bans IP addresses that show malicious behavior — specifically brute-force login attempts against SSH, FTP, cPanel, WordPress, mail servers, and web applications.

DETAILED EXPLANATION:
Fail2ban reads log files in real-time using inotify (file change notifications). When a pattern match occurs (e.g., "Failed password" in /var/log/auth.log) more than N times within a time window, Fail2ban adds an iptables rule to drop all traffic from that IP for the configured ban duration.

Question 28

server hardening and what is a step-by-step Linux server hardening checklist নত্রগা কদাই?

Accepted Answer

Server hardening is the process of reducing a server's attack surface by disabling unnecessary services, restricting access, applying security configurations, and installing protective software — transforming a default installation into a production-secure environment.

DETAILED EXPLANATION:
A freshly installed Linux server has a large attack surface: default passwords, unnecessary services running, permissive SSH settings, unpatched packages, and no intrusion detection. Hardening systematically closes these vulnerabilities following CIS (Center for Internet Security) Benchmarks and NIST guide...

Question 29

ঐ implement zero-trust security for a web application on VPS কেনা তৌগনি?

Accepted Answer

Zero-trust security eliminates the assumption that anything inside your network is safe. Every request must authenticate, every connection must be encrypted, and access is granted based on identity plus context - not network location. For VPS-hosted applications, this means SSH via certificates not passwords, application authentication for every API call, and network segmentation.

DETAILED EXPLANATION:
Zero-trust principles:
1. Never trust, always verify: Authenticate every user and device, every time
2. Least privilege access: Users get minimum permissions needed, nothing more
3. Assume brea...
