Author's Perspective: Why Enterprise Security Matters

With years of experience in IT security, I have seen organizations struggle with evolving threats. This guide covers the best practices I have implemented to fortify enterprise security, ensuring both compliance and operational efficiency.

I. Advanced Server Protection Strategies

A. Domain Controller Hardening

  • Implement RODC for branch offices
  • Disable SID history with PowerShell:
Set-ADObject -Identity "CN=Directory Service,CN=Windows NT,CN=Services" -Replace @{DsHeuristics="0000002"} Server Security Architecture

B. Server Security Best Practices

  • Incorporate encryption for data during the backup procedure to add an extra layer of protection. Follow the 3-2-1 backup rule to safeguard valuable data:refs[1-0].
  • Implement file auditing to track unwanted system modifications and service auditing to monitor services, protocols, and communicating ports:refs[3-0].

C. Recommended Security Measures

  • Use a firewall as a base layer of protection to limit connections to and from your services. This should be done early in the setup process:refs[5-1].
  • Use a Virtual Private Network (VPN) with advanced encryption and authentication protocols to secure remote access to your on-premises server:refs[7-2].

D. Server Security Checklist

  • Ensure physical security of the server as other measures may be ineffective if physical access is compromised:refs[9-2].
  • Leverage AI and ML technologies for proactive and nuanced threat detection and response:refs[11-3].

E. Securing Active Directory

  • Monitor Active Directory for signs of malicious attacks using legacy audit categories or Advanced Audit Policy:refs[13-4].
  • Implement both tactical measures focused on specific components and strategic measures that require more planning:refs[15-4].

F. Combating Advanced Persistent Threats

  • Safeguard DNS to ensure the availability of servers and other network resources:refs[17-6].
  • Use AI-driven web application firewalls for automated protection against runtime attacks and specialized threats:refs[19-6].

G. Basic Server Protection Strategies

  • Implement an SSH strategy to disable password-based authentication for certain types of data transfers:refs[21-7].
  • Include server security as part of a broader network security strategy that includes firewalls and anti-virus software:refs[23-8].

II. Client Security Configuration

A. Windows 10/11 Hardening

  • Configure Attack Surface Reduction (ASR) rules:
Set-MpPreference -AttackSurfaceReductionRules_Ids <GUID> -AttackSurfaceReductionRules_Actions Enabled

III. Public WiFi Security Architecture

A. Client Configuration Policies

  • Enforce Always On VPN
  • Disable Wi-Fi Sense via Group Policy:
Computer Configuration > Policies > Administrative Templates > Network > WLAN Service > Allow Windows to automatically connect to suggested open hotspots Public WiFi Security Measures
