Practice-Verified Commands and Codes

To enhance your understanding of cybersecurity practices, here are some practical commands and tools you can use:

Network Security

• Nmap Scan:

  nmap -sV -O target_ip 
  

  This command scans a target IP for open ports, services, and operating system details.

• Wireshark Packet Capture:

  tshark -i eth0 -w capture.pcap 
  

  Captures network traffic on the `eth0` interface and saves it to a file for analysis.

Encryption

• OpenSSL Encryption:

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

Encrypts a file using AES-256 encryption.

• GPG File Encryption:

  gpg -c file.txt 
  

Encrypts a file using GPG symmetric encryption.

Threat Detection

• ClamAV Malware Scan:

  clamscan -r /path/to/directory 
  

Scans a directory for malware using ClamAV.

• YARA Rule Scanning:

  yara -r rules.yar target_file 
  

  Scans a file using custom YARA rules for threat detection.

Compliance and Auditing

• Lynis System Audit:

  lynis audit system 
  

  Performs a comprehensive system audit for compliance and security hardening.

• OpenSCAP Compliance Check:

  oscap xccdf eval --profile xccdf_org.ssgproject.content_profile_standard /usr/share/xml/scap/ssg/content/ssg-rhel7-ds.xml 
  

Evaluates system compliance against the SCAP benchmark.
