Next up are Penetration Testers (or ethical hackers), who are the friendly attackers. They try to hack into systems to identify vulnerabilities and weaknesses. They're the ones who find the chinks in the armor so they can be fixed. They are critical to ensuring the overall security posture.

We also have Security Architects, who are the strategists. They design and oversee the overall security architecture of an organization. They're the ones who plan the layout of the castle. Incident Responders are the first responders. They handle security incidents, investigate breaches, and work to restore systems. They’re the ones who rush to the scene when the alarms go off. Security Managers are the team leaders. They manage security teams, develop security policies, and ensure compliance. They're the ones who keep the team running smoothly. And finally, there are Chief Information Security Officers (CISOs), who are the big bosses. They are responsible for the overall security strategy and direction of an organization. They're the ones who make the big decisions to protect the entire organization. Every role is vital for a strong defense, and each expert brings a unique skillset to the table. Some other roles include security auditors, who assess security controls and ensure compliance, and malware analysts, who dissect malicious software to understand its behavior and develop countermeasures. Basically, it's a team effort, and each role plays a vital part in protecting our digital world.
