Which statement about attackers and defenders in cybersecurity is accurate?

The statement that defenders must be right every time underscores the immense pressure and responsibility that cybersecurity professionals face in protecting systems. Cybersecurity defenders are tasked with anticipating threats, implementing security measures, and responding to incidents effectively. If defenders fail to identify or mitigate a single threat, it can lead to significant consequences, including data breaches, financial loss, and reputational damage.

This concept emphasizes the notion of "security in depth," where multiple layers of defense are implemented to provide redundancy and mitigate risks. Defenders aim to be proactive and preemptive in their strategies, which involves constant vigilance and continual learning about evolving threats. Because the attackers only need to succeed once to compromise a system, while defenders must maintain a perfect track record to ensure security, the responsibility on defenders is particularly high.

In contrast, the other options do not accurately depict the dynamics of cybersecurity. Attackers do not have to succeed in all steps to achieve their objectives, and while both parties operate in a challenging environment, it is not accurate to say they have equal chances of success. Additionally, although some attackers may have significant resources at their disposal, defenders also increasingly utilize advanced technologies and collaborative strategies to enhance their protective measures.
