Linux: Getting system info
One needs to be familiar with certain shell commands to investigate system and network configurations and identify vulnerabilities in a Linux system and other processes. Some of the useful ones are: whoami - to find out the current user, and who to identify logged-in users, particularly useful during reverse shell access on a host. uname - prints system information, which is helpful for gathering details about the machine's hardware, kernel release version and operating system. netstat- provides network status. There are many more commands that can reveal a wealth of information about the user, system, and network. These commands also expose vulnerabilities that can be exploited by either an attacker or a security tester to close security gaps.
