Introduction of EDR, NDR and Deception Technology on a Group level

The Evolution of Cybersecurity Threats and the Need for NDR and EDR – Over the past few decades, cybersecurity threats have evolved significantly in complexity, frequency, and impact. Early threats were often limited to individual viruses or worms targeting specific systems, with attackers seeking to disrupt operations or cause general inconvenience. As technology advanced, cyber threats became more sophisticated, moving beyond simple malware to more organized and targeted attacks.

Today, threats include advanced persistent threats (APTs), ransomware, and multi-stage attacks that exploit vulnerabilities across networks and endpoints simultaneously. Attackers now use automation, artificial intelligence, and machine learning to enhance their attack methods, making traditional security measures inadequate.

In response, cybersecurity solutions have evolved as well. Network detection and response (NDR) and endpoint detection and response (EDR) technologies emerged to address these modern challenges, enabling real-time detection and response capabilities across different attack vectors.

Introducing EDR in Cybersecurity – Endpoint Detection and Response (EDR) is a critical component of modern cybersecurity strategies designed to enhance the detection, investigation, and remediation of cyber threats targeting endpoint devices. As organizations increasingly rely on digital infrastructures, the need for robust security measures has become paramount.

Traditional security solutions like firewalls & antivirus software often fall short against sophisticated attacks, making EDR an essential tool in the cybersecurity arsenal.

Introducing NDR in Cybersecurity – Network Detection and Response (NDR) is a crucial component of modern cybersecurity strategies, designed to enhance an organization’s ability to detect and respond to cyber threats in real-time. As the threat landscape evolves with increasingly sophisticated attacks, traditional security measures such as firewalls and antivirus software are often insufficient. NDR addresses these gaps by providing continuous monitoring and analysis of network traffic, enabling organizations to identify malicious activities that may bypass conventional defenses.

Mani, the Senior Security Lead at Hansa Advanced Cybersecurity Consulting (Hansa ACSC) introduced the concepts of EDR & NDR to the Principal Partner’s team.

Experienced consultation was provided by us to our Principal Partner, around what is EDR & NDR, how do they work, importance of EDR & NDR, their role in Cybersecurity, their benefits, how will this fit into the Principal Partner’s environment, and so on.

This involved understanding the Principal Partner’s distinct capabilities, benefits to be derived, and how will this complement each other in a comprehensive cybersecurity strategy.

The conclusion being emphasized, as cyber risks continue to evolve, integrating robust EDR & NDR solutions will be extremely vital for maintaining the Principal Partner’s security.

A series of sessions were organized by Hansa ACSC to align on these two topics. Discussions on how to;

• Correlate NDR and EDR alerts for precision: By correlating anomalies detected by NDR with EDR endpoint data, you can significantly reduce false positives. Use threat intelligence platforms to enrich the data from both, enhancing the accuracy of your detection capabilities.
• Leverage NDR for encrypted traffic monitoring: Given that encryption limits NDR’s visibility, deploy techniques like traffic analysis or TLS termination points to monitor encrypted data. This can expose hidden threats without decrypting the entire traffic, thus maintaining compliance.
• Automate NDR and EDR workflows: Integrate automation between NDR and EDR platforms to ensure faster response times. For example, have NDR trigger endpoint isolation in EDR when suspicious lateral movement is detected in the network, streamlining your incident response.
• Monitor IoT devices with both NDR and EDR: Use NDR to monitor IoT devices that cannot host traditional EDR agents. Many attacks target IoT endpoints for entry into the network, so integrating NDR for such devices ensures comprehensive security.
• Utilize EDR to investigate NDR detections: When NDR flags anomalous traffic, use EDR’s forensic tools to track the root cause of the anomaly at the endpoint. This helps in understanding the entire attack chain from the network down to device-level processes.

Therefore, it was established & concluded that by the introduction of Endpoint Detection and Response & NDR into the Principal Partner’s cybersecurity framework, this will significantly enhance their ability to detect and respond advanced-threats effectively. As well as address the limitations of traditional defenses, by offering enhanced visibility into network activities & enabling proactive Threat Detection & Response.

Insider Defense in Information Security – Insider threats pose a significant risk to organizations, as they originate from individuals who have authorized access to the organization’s systems and data. These individuals can be current or former employees, contractors, or business partners. The complexity of insider threats arises from their potential for both intentional harm and unintentional mistakes, making them particularly challenging to detect and mitigate.

As a large insurance company, our Principal Partner faces the specific risk of insider threats targeting sensitive financial and customer data. They need to implement strong security measures to protect against these threats.

Mani, our Senior Security Lead, introduced the importance of Insider Threats to the Principal Partner’s team.

Expert consultation was provided to our Principal Partner around understanding their Insider Threats, different types of Insider Threats, their Impact, Detection & Mitigation methodologies, how will this benefit their environment, and so on.

This also involved understanding the Principal Partner’s existing capabilities around Insider Threat analysis, robust Gap Analysis, focused Training Sessions for staff, specialized Training Sessions for the Leadership team, and the core benefits to be derived from this Upskilling.

The conclusion being emphasized, as cyber risks continue to evolve, integrating robust EDR & NDR solutions will be extremely vital for maintaining the Principal Partner’s security.

Successions of sessions were organized by Hansa ACSC to align on this topic. Discussions around;

• Understanding Insider Threats – An insider threat is defined as any malicious activity against an organization that comes from users with legitimate access to its network, applications, or databases. This includes actions taken by employees, former employees, contractors, or even compromised service accounts. Insider threats can be categorized into three main types:
  • Malicious Insiders: Individuals who intentionally misuse their access to harm the organization for personal gain or revenge.
  • Negligent Insiders: Employees who inadvertently cause harm through careless actions, such as falling for phishing scams or failing to follow security protocols.
  • Compromised Insiders: Employees whose credentials have been stolen and are used by external attackers to gain unauthorized access.

The motivations behind these threats vary widely and can include financial gain, espionage, retaliation, or simply carelessness due to poor security practices.

• The Impact of Insider Threats – Insider threats can lead to severe consequences for organizations, including financial losses, reputational damage, compliance breaches, and operational disruptions. According to a Ponemon Institute study in 2023, insider incidents accounted for 55% of all security incidents reported. The average cost associated with these incidents has risen significantly over the years; organizations spend an average of $701,500 per incident caused by malicious insiders.

• Mitigation Strategies – To effectively defend against insider threats, organizations should implement a comprehensive insider threat mitigation program that includes the following strategies:
  • Risk Assessment: Conduct regular assessments to identify sensitive assets and evaluate vulnerabilities within the organization’s security framework.
  • Access Controls: Enforce strict access controls based on the Principle of Least Privilege (PoLP), ensuring that users have only the necessary permissions required for their roles.
  • Employee Training: Regularly train employees on security awareness and best practices to help them recognize potential insider threat behaviors and understand the importance of safeguarding sensitive information.
  • Monitoring and Detection: Utilize advanced monitoring tools such as User Behavior Analytics (UBA) and Data Loss Prevention (DLP) software to detect unusual activities that may indicate insider threats.
  • Incident Response Plan: Develop a robust incident response plan that outlines procedures for addressing suspected insider threats swiftly and effectively.
  • Collaboration across Departments: Foster collaboration between IT security teams and human resources (HR) departments to monitor employee behavior closely during critical events like layoffs or promotions.

By implementing these strategies systematically, our Principal Partner can enhance their defenses against Insider Threats, while fostering a culture of security awareness amongst the employees.

Post all alignments, it was concluded that effective management of Inside Threats requires a multifaceted approach that combines technology with effective policies and employee engagement. And this can only be achieved by periodic & effective Upskilling on various aspects of Insider Threats.

This involves strengthening cybersecurity practices, enhancing early detection and response capabilities, and focusing on employee awareness and training.

Below Key Strategies were discussed & proposed to our Principal Partner, which other Global organizations have also implemented, to enhance their defenses against such threats.

• Avoid Technology from High-Risk Nations – One of the first steps organizations can take is to avoid acquiring technology from companies based in nations identified as posing a cyber threat. The National Institute of Standards and Technology (NIST) have issued guidance recommending restrictions on purchases from specific suppliers or countries known for malicious cyber activities. For instance, U.S. lawmakers have expressed concerns about using equipment from Chinese companies like Huawei and ZTE due to potential espionage risks. However, it is crucial to note that domestic products are not inherently secure; thus, organizations should assess the security practices of all vendors regardless of their origin.

• Network Isolation – Isolating internal networks from the Internet can significantly enhance security. This approach involves creating a demilitarized zone (DMZ) that physically separates internal systems from external access. While complete isolation may not be feasible for all organizations, adopting a mindset that anticipates breaches can help in developing robust defenses. Implementing strong encryption and data-loss prevention technologies is essential to protect sensitive information even if an intrusion occurs.

• Information Sharing – Sharing cyber threat intelligence among businesses and between government and private sectors can improve overall situational awareness and response capabilities. Models like the Defense Industrial Base (DIB) encourage collaboration among companies to enhance their security postures by sharing insights on vulnerabilities and attack patterns. Regular communication between Chief Information Security Officers (CISOs) can also facilitate timely warnings about emerging threats.

• Employee Training & Awareness – Enhancing employee awareness through regular training programs is vital in mitigating risks associated with human error, which remains one of the largest vulnerabilities in cybersecurity. Organizations should conduct ongoing education about best practices in cybersecurity, including recognizing phishing attempts and understanding safe online behaviors. Engaging employees through testing their knowledge can further reinforce these lessons.

After all alignments, a unanimous conclusion was derived that a comprehensive Defense Strategy against Nation-State cyber-attacks should be devised & it should include avoiding high-risk technology vendors, isolating internal networks, sharing threat intelligence, and enhancing employee awareness through rigorous training.

By thoroughly planning & implementing these measures, our Principal Partner can significantly bolster their resilience against sophisticated cyber threats posed by Nation-States.
