A cyber-warrior is a person who engages in cyberwarfare, whether for personal reasons or out of patriotic or religious belief. Cyberwarfare may be pursued either to defend computer and information systems, or to attack them. Cyber-warriors come in different forms, depending on their roles, but all deal with information security in one form or another.
Cyber-warriors wage war using information technology. They may attack computers or information systems through hacking or other related strategies, or defend them from their counterparts. Cyber-warriors also may find better ways to secure a system by finding vulnerabilities through hacking and other means and closing those vulnerabilities before other hackers find and exploit them.
Countries that are unable to match the U.S. in terms of military technology have resorted to cyberwarfare, a method that can still do a lot of damage in terms of economic cost. Various agencies in the U.S. are under constant attack from numerous countries. In response, the U.S. military is training war veterans and wounded soldiers who can no longer fight in the field in the art of cyberwarfare to become cyber warriors and continue defending their country in this new form of battle. Given this, the term cyber-warrior has different meanings depending on context in which it is used; the term may refer to someone with malicious intent (the attacker) or a professional who is working to defend against such attackers. The latter context is an emerging career field, similar to ethical hacking.
