This question requires a long explanation, but in a nutshell, implemented in the Risk Management Framework (NIST RMF). It is a layered protection in every step of the RMF.Director - IT Infrastructure - Databases and eBusiness Specializing in Information Technology in Retaila year ago
We have a risk management team and they use multiple tools to mitigate the risk in diff levels. We have multiple layers to support it Director of IT in Educationa year ago
Absolutely, the RMF (NIST) is a sound framework, took us a while to implement but a very good layered protection process. Every steps in the framework has tasks that helped to protect the organization. The framework is managed by the Risk Team that flow through the RMF 7 steps processes.

You can’t do information security right unless you use defense in depth. As just one layer of security, such as a firewall, is incomplete security. People understand this intuitively as the physical level. They have a lock on their door, then a lock in their room, then a lock for their valuables.
Doing defense in depth means assuming the previous layer has failed, and you need the next set of layers to protect the organization.

It's a must but also consider all the SaaS applications out there. Your data not behind the castle walls anymore. Interested in how DiD plays out in SaaS and Cloud. Thoughts? Director of IT in Educationa year ago
Put your sensitive data and critical information assets in an enclave, and only allow authorized IT access via firewall and two factors authentication for user access.

As a CISO, the concept of Defense in Depth is a fundamental component of our organization's cybersecurity strategy. Defence in Depth refers to implementing multiple layers of security controls to protect against various threats and potential vulnerabilities. It ensures that if one layer is breached, additional layers are in place to mitigate the impact and prevent further compromise. Here's how we practically integrate Defense in Depth into our cybersecurity strategy:Network Segmentation: We employ network segmentation to divide our network into multiple segments or zones. This helps isolate critical assets and restricts lateral movement in the event of a breach, limiting the potential damage and minimizing the scope of an attack.
Perimeter Security: We deploy robust firewalls, intrusion prevention systems (IPS), and secure gateway devices at the network perimeter. These security measures help monitor and control incoming and outgoing network traffic, filtering out potential threats before they reach internal systems.
Identity and Access Management (IAM): We implement strong authentication mechanisms, such as multi-factor authentication (MFA), and enforce the principle of least privilege. This ensures that users and systems only have access to the resources necessary to perform their functions, reducing the risk of unauthorized access.
Endpoint Protection: We employ advanced endpoint protection solutions, including anti-malware software, host-based firewalls, and endpoint detection and response (EDR) tools. These measures help detect and prevent malicious activities on endpoints and provide visibility into potential security incidents.
Data Encryption: We employ encryption techniques to protect sensitive data at rest and in transit. This includes encrypting data on storage devices, utilizing encrypted communication protocols, and securing data backups.
Security Monitoring and Incident Response: We implement robust security monitoring systems to detect and respond to security incidents in real-time. This includes Security Information and Event Management (SIEM) solutions, intrusion detection systems (IDS), and Security Operations Center (SOC) capabilities. We have well-defined incident response plans and conduct regular incident response exercises to ensure effective response and containment.
Employee Awareness and Training: We recognize that employees play a critical role in the overall security posture of our organization. We conduct regular security awareness programs and training sessions to educate employees about best practices, social engineering threats, and their responsibilities in maintaining a secure environment.
Vendor Risk Management: We assess and manage the security risks associated with our third-party vendors and partners. This includes conducting due diligence, contractually mandating security requirements, and periodically evaluating their security practices to ensure they align with our organization's standards.
Regular Vulnerability Assessments and Penetration Testing: We conduct periodic vulnerability assessments and penetration testing to identify weaknesses in our systems and applications proactively. This helps us remediate vulnerabilities before attackers exploit them.
Continuous Monitoring and Improvement: We continuously evaluate and enhance our security controls, staying abreast of emerging threats, vulnerabilities, and best practices. We leverage threat intelligence feeds, industry information-sharing platforms, and engage in relevant security forums to stay informed and adapt our strategy accordingly.
By integrating Defense in Depth principles into our cybersecurity strategy, we create overlapping layers of security controls that work together to protect our organization's critical assets. This approach helps us reduce the risk of successful attacks, increase resilience, and effectively respond to security incidents.

Excellent, I said it was a long explanation 😉.
