As technology advances, so do cyber threats. Every new feature or line of code can become a potential vulnerability. That’s why cybersecurity is no longer optional — it’s essential.Ethical hackers, also known as white-hat hackers, work to identify and patch weaknesses before malicious attackers exploit them. Tools like Metasploit, Wireshark, and Burp Suite help simulate real-world attacks to test system defenses.Modern cybersecurity involves not just firewalls and antivirus software, but encryption, zero-trust architecture, and continuous monitoring.With the rise of IoT and AI systems, the attack surface is expanding. The future of secure development lies in integrating security from the very first line of code.
