Cyber security analysts handle data, monitor network traffic, detect malware, and run live security operations. Penetration testers try to ethically hack into company systems to test and find flaws so they can be fixed.

It depends on the specific job, but common languages include C++, PowerShell, and JavaScript.

They use tools like NMAP to find network devices, discover open ports, and gather system information. Wireshark is another key tool that captures and analyses network traffic.

One method is vulnerability assessments where they identify weak spots and misalignment in systems. Then they try to attack these weak spots to see how serious the security problems are.
