Impact

  • Information Theft and Cyber Espionage
  • Exposure of Sensitive Data
  • Unauthorized Access

Remediation

  • Logging – Log your eCommerce environment’s network activity and web server activity.
  • Passwords – Ensure that general security policies are employed including: implementing strong passwords, correct configurations, and proper administration security policies.
  • Admin Access – limit access to administrative accounts and portals to only relevant personnel and make sure they are not publicly accessible.
  • WAF – Web defacement must be stopped at the web application level. Therefore, set up a Web Application Firewall with rules to block suspicious and malicious requests.
  • Patch – Patch and upgrade any platforms and software timely and make it into a standard security policy. Prioritize patching known exploited vulnerabilities and zero-days.
  • Secure Coding – Along with network and system hardening, code hardening should be implemented within the organization so that their websites and software are secure. Use testing tools to detect any vulnerabilities in the deployed codes.
  • 2FA – Enable two-factor authentication.
  • Antivirus – Enable antivirus and anti-malware software and update signature definitions in a timely manner. Using a multi-layered protection is necessary to secure vulnerable assets
