Continued from Part 1: Understanding Modern Threats<\/a><\/em><\/p>\n

In Part 1, we exposed why traditional security plugins fail and explored the stealthy malware techniques that bypass conventional defenses. Now we get into the practical implementation: how to actually secure your WordPress site using proven, battle-tested techniques.<\/p>\n

This isn’t generic advice. Every recommendation is backed by real-world data, security research, and lessons learned from analyzing thousands of breached sites.<\/p>\n

    Attack Vector (AV) – How can it be exploited?<\/strong><\/p>\n

      \n
    • Network (N)<\/strong>: Remotely over the internet (worst)<\/li>\n
    • Adjacent (A)<\/strong>: Same local network required<\/li>\n
    • Local (L)<\/strong>: Local system access required<\/li>\n
    • Physical (P)<\/strong>: Physical access required (best)<\/li>\n<\/ul>\n

      Privileges Required (PR) – What access is needed?<\/strong><\/p>\n

        \n
      • None (N)<\/strong>: Unauthenticated (worst)<\/li>\n
      • Low (L)<\/strong>: Basic user account<\/li>\n
      • High (H)<\/strong>: Administrator account (best)<\/li>\n<\/ul>\n

        User Interaction (UI) – Must user do something?<\/strong><\/p>\n

          \n
        • None (N)<\/strong>: Fully automated attack (worst)<\/li>\n
