March 8, 2024

As IT Directors, Managers, CISOs, and CIOs at universities and colleges, you shoulder the critical responsibility of protecting your institution's data against the ever-changing threats in the cybersecurity landscape. A foundational aspect of this defense lies in how users authenticate themselves, traditionally through complex passwords. However, in light of recent trends, research, and expert guidance—most notably the recommendations from NIST Special Publication 800-63B—there is a clear movement towards the adoption of passphrases. These longer, yet more user-friendly alternatives offer a more secure method of authentication compared to traditional passwords. 

Transitioning to passphrases is not just a procedural change; it's a strategic evolution in how you approach cybersecurity defense. This change necessitates thorough planning, collective buy-in, and ongoing management. However, the benefits of this shift, including enhanced security, improved user experience, and alignment with modern security practices, make this investment worthwhile. By leading this charge, you are positioned to fortify the digital landscape of your institution, ensuring a more secure future for all stakeholders.

Rolling Out Passphrases and NIST Guidance  

Passwords are often a mix of characters, numbers, and symbols, which is difficult for users to remember. This complexity leads to insecure practices, such as writing down passwords or reusing them across multiple accounts. A more usable and secure approach emphasizes the use of passphrases—longer, easier to remember phrases that are still hard for attackers to crack. 

The rollout of passphrases within your institution should be methodical and comprehensive. To ensure a smooth transition, consider the following steps: 

  • Policy Update and Communication: Update your password policies to reflect the change to passphrases, focusing on length and memorability. Communicate the benefits and the new policy to all users, explaining why the change is occurring and how it will affect them. 
  • Training and Support: Provide training sessions and written guidelines to help users create strong passphrases. Ensure that your IT support team is prepared to assist users during the transition. 
  • Phased Implementation: Begin the rollout with a pilot group to collect feedback and adjust the process before deploying it across the entire institution. 

In line with NIST guidance (800-63B), passphrases should only be changed if they are suspected or known to be compromised. This means moving away from mandatory periodic resets, which can lead to weaker security habits. When implementing passphrase rules, consider the following: 

  • Length: The standard has been updated to require a minimum of 20 characters, allowing for more complex and secure passphrases. 
  • Complexity: Encourage the use of a mix of character types, but don't enforce it as a rule, as length is more important for security. 
  • Unpredictability: Discourage the use of common phrases or easily guessable information. 

Transitioning to a passphrase system comes with challenges, such as updating legacy systems and changing user behavior. If your institution has prescribed a passphrase compliance deadline for all departments to comply with the new standards, which differentiate between standard user accounts, elevated privileged accounts, and service accounts, there will inevitably be outliers to consider. For systems that cannot meet the standard by the deadline, conduct a thorough assessment and develop exceptions if needed. 

Embracing Educational Institution Password Governance with Passphrases 

Implementing passphrases is a vital step toward a more secure IT environment. By following the steps outlined and considering the integration of a converged security fabric, you will enhance your institution's defenses against cyber threats. Remember, the key to a successful rollout is clear communication, user education, and the support of advanced security technologies. With careful planning and execution, your passphrase policy will lead to a stronger, more resilient cybersecurity posture for your university or college. 

As you move forward with this initiative, reference our Password Safety Dos and Dont’s blog post for foundational best practices that complement the shift to passphrases.

By combining a solid understanding of password safety with the strategic implementation of passphrases, you are setting a new standard for cybersecurity in higher education. You're not only enhancing protection against potential breaches but also fostering a culture of security awareness within your institution. 

The transition from passwords to passphrases is more than just a change in policy; it's an evolution in how we think about and approach cybersecurity. It requires careful planning, community buy-in, and ongoing management, but the benefits—enhanced security, improved user experience, and alignment with modern best practices—are well worth the effort. Your leadership in this change can inspire a more secure future for the academic community. 

Leveraging Low-Cost, High-Value Identity Analytics to Strengthen Passphrase Security and Integrity 

Identity analytics plays a crucial role in enhancing the security of passphrase systems by leveraging data analysis to detect and prevent potential issues. It is also a solution that can be implemented quickly, easily to give teams instant insight across homegrown and disparate identity security environments and even plan their identity access governance roadmap. Identity analytics can address common passphrase problems in a variety of ways.  

1. Enhancing Passphrase Integrity with Identity Analytics: By utilizing identity analytics, institutions can both scan for weak passphrases and identify instances of sharing or reuse. This advanced analysis helps detect commonly used or simple phrases susceptible to breaches and recognizes behavioral patterns indicative of passphrase sharing or reuse across accounts. When such risks are identified, the system can immediately alert users and enforce the creation of stronger, unique passphrases, substantially elevating the security posture of the institution. 

2. Spotting Anomalous Behavior: Identity analytics can help identify unusual access patterns or login activities that may suggest a passphrase has been compromised. For instance, if a user's account is accessed from a geographic location that is inconsistent with their typical pattern, the system can flag it for further investigation.

3. Automating Risk Assessments: By continuously monitoring user activities and access patterns, identity analytics can calculate risk scores for individual users or groups. If a user's risk score increases due to questionable activities related to their passphrase use, proactive measures can be taken, such as prompting a passphrase change or implementing additional security controls. 

4. Streamlining Compliance Reporting: Identity analytics can assist in generating compliance reports that demonstrate adherence to passphrase policies and regulatory requirements. This helps universities and colleges provide evidence of their efforts to protect sensitive data through effective passphrase management.

5. Enhancing Incident Response: In the event of a security breach, identity analytics can help trace the incident back to a particular user account or passphrase. This information is critical for understanding how the breach occurred and for improving security measures to prevent future incidents. 

6. Optimizing User Experience: By analyzing how users interact with passphrase systems, identity analytics can offer insights into user behavior and experience. These insights can drive improvements in passphrase management processes, making them more user-friendly while maintaining security. 

7. Predictive Analytics: Advanced identity analytics can use machine learning algorithms to predict future risks based on historical data. This predictive capability allows IT security teams to address potential passphrase-related issues before they become actual breaches. 

Overall, by providing actionable intelligence, identity analytics enhances the security of passphrase systems and helps mitigate risks associated with user credentials. It allows universities and colleges to be proactive in their approach to cybersecurity, addressing passphrase problems before they can be exploited by malicious actors.
