📖 What is Due Care?

Due Care represents the level of responsibility and caution a prudent individual would exercise under similar circumstances to prevent foreseeable harm. It involves proactively implementing reasonable security controls and safeguards to protect assets and mitigate risks, demonstrating responsible behavior.

🥋 Sensei Says:

"Due Care is about taking action to prevent harm. It’s a legal concept related to negligence. The exam often contrasts Due Care with Due Diligence; remember Due Care is *doing* something, while Due Diligence is *knowing* something. Failure to exercise Due Care can lead to legal liability."

🔑 What are the Key Concepts of Due Care?

  • Due Care is a legal standard of behavior, requiring proactive security measures to prevent foreseeable harm and potential liability.
  • It focuses on the *implementation* of reasonable security controls, like patching systems and enforcing strong passwords, not just identifying risks.
  • Demonstrating Due Care involves documenting security policies, procedures, and training to prove responsible actions were taken.
  • Failure to exercise Due Care can result in negligence claims, fines, and reputational damage for an organization.
  • Due Care is often contrasted with Due Diligence; Diligence is knowing the risks, while Care is acting to mitigate them.

🎯 How does Due Care appear on the CISSP Exam?

You may be asked to identify which action demonstrates Due Care in a scenario where a company experiences a data breach due to unpatched vulnerabilities.

A scenario might describe a company lacking a formal incident response plan – expect questions about whether this demonstrates a lack of Due Care.

Expect questions about the legal ramifications of failing to implement reasonable security controls, and how that relates to the concept of Due Care.

❓ Frequently Asked Questions

How does Due Care relate to the concept of 'reasonable security'?

’Reasonable security’ is the practical application of Due Care. It means implementing controls appropriate for the organization’s size, industry, and risk profile, balancing cost and effectiveness.


What’s the difference between Due Care and Due Diligence in a legal context?

Due Diligence is the investigation to identify risks; Due Care is the action taken to mitigate those risks. You must *know* the risks (Diligence) and then *act* responsibly (Care) to avoid liability.


Can simply following industry best practices guarantee Due Care?

Not necessarily. While helpful, best practices aren’t a guaranteed defense. Due Care requires a tailored approach based on the organization’s specific circumstances and a demonstrable effort to protect assets.
