SOC Analyst Guide: Your Path to Cybersecurity Success

You Should Know:

1. Networking Basics for SOC Analysts:

• Command to check network interfaces on Linux:

  ifconfig
  

• Command to check active connections:

  netstat -tuln
  

2. Cryptography Essentials:

• Generate an MD5 hash for a file:

  md5sum filename
  

• Encrypt a file using OpenSSL:

  openssl enc -aes-256-cbc -salt -in file.txt -out file.enc
  

3. Endpoint Security:

• Check for open ports on a system:

  nmap -sT -O localhost
  

• List running processes on Windows:

  tasklist
  

4. SIEM Tools:

• Search logs in Splunk:

  index=main sourcetype=access_combined status=200
  

• Query logs in QRadar:

  SELECT * FROM events WHERE LOGSOURCETYPENAME(devicetype) = 'Linux'
  

5. Threat Detection:

• Use `tcpdump` to capture network traffic:

  tcpdump -i eth0 -w capture.pcap
  

• Analyze captured traffic with Wireshark:

  wireshark capture.pcap
  

6. SOC Automation:

• Automate log analysis with a Python script:

  import re
  with open('logfile.log', 'r') as file:
  for line in file:
  if re.search('ERROR', line):
  print(line)
  

7. Cloud Security:

• Check AWS S3 bucket permissions:

  aws s3api get-bucket-acl --bucket my-bucket
  

• List all Azure resources:

  Get-AzResource
  

8. Vulnerability Management:

• Scan for vulnerabilities using Nmap:

  nmap --script vuln target_ip
  

• Check for outdated packages on Linux:

  apt list --upgradable
  

9. Incident Response:

• Create a memory dump on Windows:

  procdump -ma <process_id>
  

• Analyze memory dump with Volatility:

  volatility -f memory.dump --profile=Win10x64 pslist
  

10. Threat Intelligence:

• Query VirusTotal for file analysis:

  curl --request POST --url 'https://www.virustotal.com/vtapi/v2/file/scan' --form 'apikey=your_api_key' --form 'file=@file_to_scan'
