Definition of Offensive Security

My definition of offensive security is any proactive approach to identify risks and weaknesses within an organization by mimicking an adversarial technique. So that's penetration testing, network and web application testing, red teaming, as well as even threat hunting and social engineering. It's basically mimicking the adversarial threat actor, right? You're trying to break into a company using real world techniques used by attackers. You want to identify and think like that attacker, so you can identify all the weaknesses and the loopholes that ultimately cause a breach in your organization. You could do that by doing penetration testing, red teaming, testing your web applications for any type of flaws in code, your network infrastructure, whether it be in cloud or on premise, and even social engineering trying to attempt to phish users or physically get into an organization, as well as threat hunting, proactively looking for those threats within your organization. Are they actively being exploited on machines.
