The demand for skilled SOC analysts with expertise in ELK (Elasticsearch, Logstash, Kibana) and Microsoft Sentinel is growing rapidly in the cybersecurity field. This full remote position offers professionals the opportunity to work with cutting-edge SIEM technologies while enjoying location flexibility.
You Should Know:
ELK Stack Fundamentals:
1. Install Elasticsearch on Linux:
wget https://artifacts.elastic.co/downloads/elasticsearch/elasticsearch-8.10.0-amd64.deb sudo dpkg -i elasticsearch-8.10.0-amd64.deb sudo systemctl enable elasticsearch.service sudo systemctl start elasticsearch.service
2. Configure Logstash pipeline:
input {
file {
path => "/var/log/*.log"
start_position => "beginning"
}
}
filter {
grok {
match => { "message" => "%{COMBINEDAPACHELOG}" }
}
}
output {
elasticsearch {
hosts => ["localhost:9200"]
}
}
Microsoft Sentinel Implementation:
1. Connect Azure resources to Sentinel:
Connect-AzAccount New-AzSentinelDataConnector -ResourceGroupName "MyRG" -WorkspaceName "MyWorkspace" -AzureActiveDirectory
2. Create custom detection rules:
SecurityEvent | where EventID == 4625 | summarize FailedAttempts=count() by Account | where FailedAttempts > 5
3. Enable threat intelligence feeds:
az sentinel threat-intelligence indicator create --workspace-name MyWorkspace --resource-group MyRG --display-name "MaliciousIP" --pattern "[ipv4-addr:value = '192.168.1.100']" --pattern-type "ipv4-addr"
SOC Best Practices:
1. Create automated alert triage script:
import pandas as pd
from elasticsearch import Elasticsearch
es = Elasticsearch(['http://localhost:9200'])
alerts = es.search(index='alerts-*', body={'query': {'match': {'status': 'new'}}})
df = pd.json_normalize(alerts['hits']['hits'])
critical_alerts = df[df['_source.severity'] == 'critical']
2. Implement log rotation for security logs:
sudo nano /etc/logrotate.d/security
Add configuration:
/var/log/secure {
daily
missingok
rotate 7
compress
delaycompress
sharedscripts
postrotate
/usr/bin/systemctl restart rsyslog >/dev/null 2>&1 || true
endscript
}
What Undercode Say:
The SOC analyst role requires continuous learning and hands-on experience with security tools. Mastering both open-source (ELK) and enterprise (Sentinel) solutions makes you valuable in today’s market. Practice these essential commands regularly:
Linux Security Monitoring:
journalctl -u sshd --since "1 hour ago" | grep "Failed password" ausearch -m execve -ts today | aureport -f -i
Windows Security Auditing:
Get-WinEvent -FilterHashtable @{LogName='Security';ID=4625,4648} -MaxEvents 50
Get-Service | Where-Object {$_.Status -eq "Running"} | Export-CSV running_services.csv
Network Security:
tcpdump -i eth0 'port 53' -w dns_queries.pcap tshark -r capture.pcap -Y "http.request" -T fields -e http.host
Expected Output:
Demonstrated proficiency in ELK stack configuration, Sentinel rule creation, and practical SOC operations through verifiable commands and scripts.
