Use a Firewall &amp; Intrusion Prevention System (IPS)<\/strong><\/h3>\n\n\n\n<p>A&nbsp;<strong>firewall<\/strong>&nbsp;filters incoming\/outgoing traffic, while an&nbsp;<strong>IPS<\/strong>&nbsp;detects and blocks malicious activity.<\/p>\n\n\n\n<p>\ud83d\udd39&nbsp;<strong>Best Practices:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Configure\u00a0<strong>hardware and software firewalls<\/strong>\u00a0(e.g., CSF, iptables)<\/li>\n\n\n\n<li>Set\u00a0<strong>default deny policies<\/strong>\u00a0(only allow necessary ports)<\/li>\n\n\n\n<li>Enable\u00a0<strong>real-time monitoring<\/strong>\u00a0for suspicious traffic<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>2. Enable DDoS Protection<\/strong><\/h3>\n\n\n\n<p>Distributed Denial-of-Service (DDoS) attacks can cripple your server.<\/p>\n\n\n\n<p>\ud83d\udd39&nbsp;<strong>Best Practices:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Use\u00a0<strong>cloud-based DDoS mitigation<\/strong>\u00a0(e.g., Cloudflare, Akamai)<\/li>\n\n\n\n<li>Configure\u00a0<strong>rate limiting<\/strong>\u00a0to block excessive requests<\/li>\n\n\n\n<li>Deploy\u00a0<strong>Anycast DNS<\/strong>\u00a0to distribute traffic<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>3. Implement Strong Password Policies &amp; Multi-Factor Authentication (MFA)<\/strong><\/h3>\n\n\n\n<p>Weak passwords are a leading cause of breaches.<\/p>\n\n\n\n<p>\ud83d\udd39&nbsp;<strong>Best Practices:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Enforce\u00a0<strong>12+ character passwords<\/strong>\u00a0with symbols, numbers, and uppercase letters<\/li>\n\n\n\n<li>Use\u00a0<strong>SSH key authentication<\/strong>\u00a0instead of passwords where possible<\/li>\n\n\n\n<li>Enable\u00a0<strong>MFA for all admin logins<\/strong>\u00a0(Google Authenticator, Authy)<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>4.
