Another View

As with so many things in life, perception is seldomly reality.

There is a word – holistic. And a phrase “holistic approach to security”.

Taking a holistic approach to defending against cyber attacks means considering and addressing all aspects of cybersecurity comprehensively rather than focusing on isolated elements. This approach encompasses a broad range of strategies and measures designed to protect an organization’s entire digital ecosystem. Here are key components of a holistic cybersecurity strategy:

1. Technology and Infrastructure:
   • Network Security: Implementing firewalls, intrusion detection/prevention systems, and secure network architecture.
   • Endpoint Security: Protecting all devices connected to the network, including computers, mobile devices, and IoT devices.
   • Data Encryption: Ensuring that data is encrypted both in transit and at rest to prevent unauthorized access.
2. Human Factors:
   • Training and Awareness: Regularly educating employees about phishing, social engineering, and other common cyber threats.
   • Access Control: Enforcing strict access controls to ensure that only authorized personnel have access to sensitive information.
   • Incident Response Plans: Preparing staff to respond quickly and effectively to security incidents.
3. Processes and Policies:
   • Regular Audits and Assessments: Conducting frequent security audits and vulnerability assessments to identify and mitigate risks.
   • Security Policies: Developing and enforcing comprehensive security policies and procedures.
   • Compliance: Ensuring compliance with relevant regulations and standards, such as GDPR, HIPAA, or ISO/IEC 27001.
4. Physical Security:
   • Securing Physical Access: Controlling physical access to critical IT infrastructure and ensuring that only authorized personnel can enter sensitive areas.
   • Surveillance and Monitoring: Using surveillance cameras and monitoring systems to detect and respond to physical security breaches.
5. Incident Management:
   • Detection and Monitoring: Implementing continuous monitoring to detect anomalies and potential threats in real-time.
   • Response and Recovery: Establishing a clear incident response plan to contain and remediate attacks swiftly, and a recovery plan to restore normal operations.
6. Integration and Collaboration:
   • Cross-Functional Collaboration: Ensuring collaboration between IT, legal, compliance, and other departments to create a unified defense strategy.
   • Third-Party Security: Managing and monitoring the security practices of third-party vendors and partners.
7. Continuous Improvement:

   • Feedback Loops: Learning from past incidents and continuously improving security measures.

By adopting a holistic approach, organizations can create a robust defense mechanism that addresses the multifaceted nature of cyber threats, ensuring comprehensive protection of their digital assets.

The list is a good start to understanding a robust set of security requirements. However, missing from the list is understanding culture and human behavior.

From Treadstone-71:

“The Mind at War The Role of INTJ Personalities in Cyber Defense

Our analysis explores the intricate dynamics of INTJ personality types within cyber defense and intelligence teams, mainly focusing on how adversaries exploit their traits in cognitive warfare. The research underscores the propensity of INTJs to pride themselves on their knowledge and analytical skills, highlighting how these characteristics make them susceptible to sophisticated manipulation tactics during cyber-attack or threat scenarios. We examine various strategies employed by adversaries, such as intellectual ego flattery, presenting misleading information, creating echo chambers, and exploiting the INTJ’s preference for complex, technological solutions.

The paper further examines the broader implications of INTJ-dominated teams in cybersecurity. We identify critical areas of potential vulnerability, including a tendency to focus on long-term strategies potentially at the expense of immediate threats, a preference for working independently, which may hinder necessary collaboration, and a propensity to undervalue emotional intelligence. Additionally, the analysis considers the INTJ’s discomfort with hierarchical structures and their inclination towards complex solutions, which might overlook simpler yet effective alternatives.

In response to these identified vulnerabilities, the research advocates fostering a culture of critical thinking, diversity in problem-solving approaches, and continuous training to recognize and mitigate cognitive biases. It emphasizes cultivating humility, encouraging diverse viewpoints, and implementing checks and balances in decision-making processes among INTJ-dominated groups. The paper highlights the necessity of balancing technological prowess with an awareness of its limitations and potential for manipulation.

The analysis concludes that building resilience in cyber defense and intelligence teams requires a holistic approach, such as adapting strategies to counter potential manipulations, fostering adaptability, promoting continuous learning in emotional intelligence and interpersonal skills, and integrating diverse perspectives and methodologies. By doing so, teams develop robust defenses against the evolving landscape of cyber threats and ensure a cohesive and effective response to cyber warfare challenges.”

A key take away is that an individual/team can be extremely technically competent, and have a deep understanding of security controls, but unless that individual/team understands differences in cultures and how those differences influences choices, previous efforts will fail.

Endpoint Detection and Response

It is not wise to think that if your desktop, laptop, tablet and/or cell phone has virus protection, that the resources are not vulnerable to compromise. If there is value for a resource and that value is more than the cost to compromise, the resource is a worthwhile target.

Need to understand what Endpoint Detection (EDR) and Response is and why there is value in by passing it.

Endpoint Detection and Response (EDR) is a cybersecurity technology designed to monitor, detect, and respond to threats on endpoints, such as desktops, laptops, servers, and mobile devices. Here’s a detailed explanation:

Analyzing Bypass of EDR or XDR on a Remote Machine vs. Local Machine

Introduction

Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) systems are crucial for maintaining the security of computing environments. When a potential bypass of these systems is suspected, it’s essential to analyze the incident carefully to understand how the security measures were circumvented. This analysis is best conducted on a remote machine rather than the local machine where the bypass is suspected. Here’s why:

1. Preservation of Evidence

• Integrity of Data: Analyzing on a remote machine helps preserve the integrity of the evidence. Local analysis can alter critical logs or artifacts, making it harder to reconstruct the sequence of events accurately.
• Chain of Custody: Remote analysis maintains a clear chain of custody, which is vital if the analysis results need to be used in legal proceedings.

2. Isolation of Threats

• Containment: Conducting the analysis remotely ensures that any active malicious processes or files do not continue to operate or propagate on the local machine, potentially causing further damage.
• Preventing Re-Infection: If the local machine is still compromised, it could interfere with the analysis process or reintroduce the threat, undermining the investigation.

3. Unbiased Analysis Environment

• Clean Environment: A remote analysis is performed in a clean and controlled environment, free from the potential influences or manipulations that might exist on the compromised local machine.
• Consistent Baseline: Remote systems can be standardized to provide a consistent baseline for analysis, ensuring that findings are based on the evidence and not influenced by the local machine’s unique configurations or state.

4. Resource Management

• Performance Overhead: Analyzing on the local machine can consume significant system resources, impacting the performance and usability of the machine for other critical tasks.
• Specialized Tools: Remote analysis environments can be equipped with specialized tools and resources that might not be available or feasible to run on the local machine.

5. Expertise and Collaboration

• Access to Specialists: Remote analysis allows security experts and analysts to collaborate more effectively, regardless of their physical location. This ensures that the investigation benefits from a broader range of expertise.
• Centralized Analysis: Using remote systems can centralize the analysis process, making it easier to manage, document, and share findings with relevant stakeholders.

Conclusion

Conducting the analysis of a bypass of EDR or XDR on a remote machine rather than the local machine provides numerous advantages. It ensures the integrity and preservation of evidence, contains and isolates threats, provides an unbiased analysis environment, optimizes resource management, and facilitates expertise and collaboration. These benefits collectively lead to a more thorough and reliable investigation, which is essential for understanding and mitigating the bypass effectively.

Word to the wise

Do not assume that because your resource has end point protection in place, that the resource is not vulnerable to attack. If the resource has value, and the value is less than the cost to attack the resource, the resource will be attacked–and compromised.
