This chart provides a comprehensive overview of critical IT assets in an organization, their associated risks, and necessary security controls. From Active Directory and privileged accounts to servers, cloud infrastructure, and even printers or CCTV systems, each asset requires tailored protection strategies.

You Should Know:

1. Active Directory (AD) Security

  • Risks: Privilege escalation, credential theft, Golden Ticket attacks.
  • Controls:
  • Enable Multi-Factor Authentication (MFA).
  • Implement Least Privilege Access (LPA).
  • Use Microsoft LAPS (Local Administrator Password Solution).
  • Monitor with Windows Event Logs and SIEM tools.

Commands:

 Check for suspicious logins in Windows Event Logs 
Get-WinEvent -LogName Security | Where-Object {$<em>.ID -eq 4625 -or $</em>.ID -eq 4648}

Enable LAPS 
Import-Module AdmPwd.PS 
Update-AdmPwdADSchema 
Set-AdmPwdComputerSelfPermission -OrgUnit "OU=Computers,DC=domain,DC=com"

2. Server Hardening (Linux/Windows)

  • Risks: Unpatched vulnerabilities, misconfigurations, brute-force attacks.
  • Controls:
  • Apply CIS Benchmarks.
  • Disable unnecessary services (sshd, ftp).
  • Use firewalls (iptables/ufw/nftables).

Linux Commands:

 Disable SSH root login 
sudo sed -i 's/PermitRootLogin yes/PermitRootLogin no/' /etc/ssh/sshd_config 
sudo systemctl restart sshd

Check open ports 
sudo netstat -tulnp

Harden with UFW 
sudo ufw enable 
sudo ufw allow 22/tcp 
sudo ufw deny all

Windows Commands:

 Disable SMBv1 (vulnerable protocol) 
Disable-WindowsOptionalFeature -Online -FeatureName smb1protocol

Enable Windows Defender Firewall 
Set-NetFirewallProfile -Profile Domain,Public,Private -Enabled True

3. Cloud Infrastructure (AWS/Azure/GCP)

  • Risks: Misconfigured S3 buckets, exposed APIs, weak IAM policies.
  • Controls:
  • Enable CloudTrail (AWS) / Azure Monitor.
  • Use Infrastructure as Code (IaC) scanning (Terraform, Checkov).

AWS CLI Commands:

 Check for public S3 buckets 
aws s3api list-buckets --query "Buckets[].Name" 
aws s3api get-bucket-acl --bucket BUCKET_NAME

Enable MFA for root account 
aws iam enable-mfa-device --user-name root --serial-number MFA_SERIAL --authentication-code1 123456 --authentication-code2 654321

4. Network Devices (Routers, VPNs, Printers)

  • Risks: Default credentials, firmware vulnerabilities.
  • Controls:
  • Change default passwords.
  • Disable Telnet, use SSH.
  • Segment networks with VLANs.

Router Commands (Cisco):

enable 
configure terminal 
no ip http server 
no cdp run 
enable secret STRONG_PASSWORD 
service password-encryption

5. Endpoint Security (Workstations, BYOD)

  • Risks: Malware, phishing, unauthorized access.
  • Controls:
  • EDR/XDR solutions (CrowdStrike, SentinelOne).
  • Disk Encryption (BitLocker/LUKS).

Linux Disk Encryption:

sudo cryptsetup luksFormat /dev/sdX 
sudo cryptsetup open /dev/sdX encrypted_drive 
sudo mkfs.ext4 /dev/mapper/encrypted_drive

What Undercode Say:

A holistic cybersecurity strategy must cover all IT assets, not just high-profile ones. Unsecured printers, IoT devices, and backup systems often become attack vectors. Regular audits, patch management, and zero-trust policies are crucial.

Prediction:

As AI-driven attacks rise, automated security controls (like AI-powered SIEMs) will become essential for real-time threat detection.

Expected Output:

  • A hardened Active Directory with MFA and LAPS.
  • Secure cloud configurations with least-privilege IAM.
  • Encrypted endpoints and segmented networks.
  • Continuous monitoring via SIEM/EDR solutions.
