The cyber-arms industry is an industry that sells weapons that are used on computers or the internet. These weapons can be used by governments or organizations to protect their computer networks from attack. Cyber-weapons can be used to launch protective measures to keep other computers from getting into the network or to launch attacks against the computers of other people or organizations. These weapons can also be used to steal information from other people or organizations. It's like using guns in the real world, except the weapons are used on computers instead.
