4. Application Penetration Testing:

• Command to run an Nmap scan to detect open ports and services:

  nmap -sV -O target-ip
  

• Command to run a Nikto scan for web vulnerabilities:

  nikto -h http://target-ip
  

5. Infrastructure/Network Penetration Testing:

• Command to perform a SYN scan using Nmap:

  nmap -sS target-ip
  

• Command to run a vulnerability scan using OpenVAS:

  openvasmd --get-tasks
  

6. SIEM Usage:

• Command to search for specific logs in Elasticsearch:

  curl -X GET "localhost:9200/logs-*/_search?q=status:404"
  

• Command to ingest logs into Splunk:

  splunk add monitor /var/log/syslog -index main
  

7. Networking:

• Command to display routing table in Linux:

  netstat -r
