Ana Griman’s experience highlights a strategic approach to conquering the challenging CISSP certification by breaking it into manageable steps: CISM ➡️ CISA ➡️ CISSP. Here’s how you can replicate her success, along with practical commands and tools to aid your preparation.

You Should Know:

1. Start with CISM and CISA

These ISACA certifications cover ~40% of CISSP domains (e.g., Risk Management, Security Operations). Use these tools to study:
– Linux commands for security practice: 


<h1>Analyze logs for security events (CISM Domain 4: Incident Management)</h1>

grep "failed" /var/log/auth.log # Check failed login attempts
journalctl -u sshd --no-pager # View SSH service logs (systemd systems)

– Windows commands for governance (CISA Domain 1: Audit Processes): 

Get-EventLog -LogName Security -Newest 50 # Extract recent security events
auditpol /get /category:* # Check audit policies

2. CISSP Preparation

Focus on the 8 domains using hands-on labs:

  • Encryption practice (Domain 3: Security Architecture): 
    openssl aes-256-cbc -in secret.txt -out encrypted.enc -k passphrase # Encrypt file
openssl aes-256-cbc -d -in encrypted.enc -out decrypted.txt -k passphrase # Decrypt
  • Network security (Domain 4: Communication and Network Security): 
    nmap -sV 192.168.1.1 # Scan for open ports/services
tcpdump -i eth0 'port 80' -w http.pcap # Capture HTTP traffic

3. Exam Simulation
