Here’s a reality check:
It’s not just about “knowing tools.” It’s about mastering concepts that keep the digital world safe.
You don’t need 10 certifications.
Here’s exactly what you need to be effective from Day One:
The SOC L1 Blueprint (Save this):
🛡️ Firewalls – Network, Host-Based, and NGFWs.
🛡️ IDS/IPS – Detect and block suspicious network traffic.
🛡️ SIEM – Your central nervous system for alerts.
🛡️ EDR – Protect endpoints like your life depends on it.
🛡️ Antivirus/Anti-Malware – Basics that still matter.
🛡️ VPN – Secure remote access.
🛡️ NAC – Gatekeeper for devices.
🛡️ DLP – Stop sensitive data leaks.
🛡️ Threat Intelligence – Get ahead of attackers.
🛡️ Vulnerability Scanners – Find cracks before hackers do.
🛡️ Email Security – Block phishing, spam, malware.
🛡️ WAF – Protect your web apps.
🛡️ Packet Sniffers – Wireshark is your new best friend.
🛡️ DNS Security – Protect where your users go.
🛡️ SOAR – Automate what slows you down.
🛡️ Cloud Security – Guard AWS, Azure, GCP.
🛡️ Honeypots – Catch bad actors red-handed.
🛡️ NTA – Spot stealthy attacks.
🛡️ Phishing Protection – Outsmart social engineering.
> “Tools change. Concepts endure.”
Master the foundation now, and you’ll adapt to ANY tool tomorrow.
You Should Know:
Essential Linux Commands for SOC Analysts
Network Analysis tcpdump -i eth0 -w capture.pcap tshark -r capture.pcap -Y "http.request" Log Analysis grep "Failed password" /var/log/auth.log journalctl -u sshd --no-pager Process Monitoring ps aux | grep "suspicious_process" lsof -i :443 File Integrity Checking md5sum /etc/passwd tripwire --check Threat Hunting clamscan -r /home chkrootkit
Windows Security Commands
Event Log Analysis
Get-WinEvent -FilterHashtable @{LogName='Security'; ID=4625}
Process & Network
netstat -ano | findstr "ESTABLISHED"
tasklist /svc
PowerShell Logging (Enable Script Block Logging)
Set-ItemProperty -Path "HKLM:\SOFTWARE\Policies\Microsoft\Windows\PowerShell\ScriptBlockLogging" -Name "EnableScriptBlockLogging" -Value 1
Check Scheduled Tasks
Get-ScheduledTask | Where-Object { $_.State -ne "Disabled" }
SIEM Queries (Splunk Example)
index=firewall action=block src_ip= | stats count by src_ip index=windows EventCode=4688 | search "New Process Name"=powershell
Wireshark Filters
– `http.request.method == “POST”`
– `tcp.port == 443 && ssl.handshake.type == 1`
– `dns.qry.name contains “malicious.com”`
EDR & Threat Hunting
YARA Rule for Malware Detection
rule Detect_Mimikatz {
strings:
$mz = "MZ"
$str1 = "mimikatz" nocase
condition:
$mz at 0 and $str1
}
What Undercode Say:
A SOC analyst’s effectiveness isn’t measured by tool familiarity alone but by conceptual depth.
- Firewalls: Master `iptables` (Linux) and `netsh advfirewall` (Windows).
- IDS/IPS: Use
snort -A console -q -c /etc/snort/snort.conf. - Log Analysis:
awk,sed, and `ELK Stack` are your allies. - EDR: Learn memory forensics with
Volatility. - Threat Intel: Automate feeds with `MISP` or
ThreatFox. - SOAR: Script in Python (
requests,pandas).
“The best analysts automate the boring, focus on the critical.”
Expected Output:
A SOC-ready analyst who:
✔️ Understands network protocols (TCP/IP, HTTP, DNS).
✔️ Writes basic scripts (Bash, Python, PowerShell).
✔️ Knows log analysis (SIEM, Sysmon, ELK).
✔️ Uses Wireshark and tcpdump effectively.
✔️ Applies YARA and Sigma rules for detection.
Master these, and no SOC will be out of reach. 🚀
