Study Notes
Installing VirtualBox
- VirtualBox allows you to run Kali Linux in a virtual machine alongside Windows or macOS without overwriting the existing OS.
- Download VirtualBox from the official site, selecting the appropriate package for your OS.
- Ensure to download the latest version to access the newest features and fixes.
- The installation process includes a familiar Setup Wizard; follow prompts to click Next until reaching the installation confirmation screen.
- You may need to allow the installation of necessary virtual networking devices during the setup.
Setting Up Your Virtual Machine
- Open VirtualBox after installation to access the VirtualBox Manager.
- Create a new virtual machine by selecting 'New' and configuring it with a meaningful name, and selecting 'Linux' as the type with 'Debian (64-bit)' for Kali Linux.
- When allocating RAM, do not exceed 25 percent of your total system RAM for optimal performance.
- The upcoming chapters cover various topics, including web server creation, remote access tools, and database vulnerabilities, enhancing your Linux and hacking skills.
Understanding Ethical Hacking
- Ethical hacking, or white hat hacking, involves exploiting systems to identify vulnerabilities.
- The field is divided into two sectors: penetration testing for companies and military/cyber intelligence roles, both experiencing rapid growth.
- Penetration testing serves as a legal assessment of a firm’s security; organizations typically conduct a preliminary vulnerability assessment before hiring penetration testers.
Techniques in Penetration Testing
- Organizations increasingly rely on assessments from external security firms to discover and address vulnerabilities.
- A penetration test legally demonstrates weaknesses in a network, providing insight into where organizations need to invest resources for security improvements.
Cyber Espionage
- Cyber warfare and espionage activities are common among nations, reflecting the growing importance of cybersecurity.
Working with Snort in Kali Linux
- Snort can be installed via the Kali repository using the command
apt-get install snortif not pre-installed. - The basic command for displaying file content is
cat, but alternatives likehead,more, andlessenhance viewing and navigation through files.
File Viewing and Navigation Commands
headshows the first 10 lines of a file by default, but this can be modified to display more or fewer lines.moreallows viewing content one page at a time, whilelessoffers enhanced functionality, including searching within the file.- The ability to use search commands (e.g.,
/output) withinlesscan highlight specific configuration parameters.
Manipulating the Domain Name System (DNS)
- DNS is crucial for translating domain names to IP addresses, facilitating internet access.
- The
digcommand is valuable for gathering DNS information, aiding in reconnaissance before attacks. - Querying a domain with
digand options likensreveals information on nameservers and associated IP addresses, which can be critical for planning cybersecurity maneuvers.
