You Should Know:

1. Splunk Commands for Security Monitoring:

• Search for failed login attempts:

  index=main sourcetype=linux_secure "Failed password"
  

• Monitor SSH access logs:

  index=main sourcetype=linux_secure "sshd"
  

• Track suspicious IP addresses:

  index=main sourcetype=access_combined | stats count by src_ip | where count > 100
  

2. Linux Commands for Security Audits:

• Check open ports:

  sudo netstat -tuln
  

• List running processes:

  ps aux
  

• Inspect system logs for anomalies:

  sudo tail -f /var/log/syslog
  

3. Windows Commands for Security:

• Check active network connections:

  netstat -an
  

• List scheduled tasks:

  schtasks /query /fo LIST /v
  

• Scan for malware using Windows Defender:

  MpCmdRun.exe -Scan -ScanType 2
  

4. AI in Cybersecurity:

• Use Python to analyze log data with machine learning:

  import pandas as pd
  from sklearn.ensemble import IsolationForest</li>
  </ul>
  
  <h1>Load log data</h1>
  
  data = pd.read_csv('logs.csv')
  model = IsolationForest(contamination=0.01)
  data['anomaly'] = model.fit_predict(data[['feature1', 'feature2']])
  print(data[data['anomaly'] == -1])
  

  What Undercode Say:

  The integration of Splunk into Cisco highlights the critical role of data platforms in modern cybersecurity. As the traditional perimeter fades, organizations must focus on observability, adaptability, and leveraging AI to stay ahead of threats. Practical commands and tools, such as Splunk queries, Linux security audits, and Windows Defender scans, are essential for maintaining robust security postures. Continuous learning and staying updated with industry trends, as emphasized by leaders like Jeetu Patel, are key to thriving in the ever-evolving tech landscape.
