In today's digital landscape, enterprises face the constant threat of cyberattacks that can compromise their networks and disrupt business operations. When a major breach occurs, the challenge becomes finding the fastest path to recovering safely.  Deloitte and Zscaler, renowned for their expertise in cybersecurity, offer a robust solution for recovery and prevention, utilizing advanced technology and providing expert guidance.

Understanding Enterprise Recovery:

​Enterprise Recovery refers to the process of regaining control and trust in an organization's digital systems and core infrastructure after a major breach. When trust and control are lost, business-critical services are disrupted, revenue generation is halted, and the entire organization comes to a standstill.

The goal of Enterprise Recovery is to identify the minimum viable services required to ensure the survival of the enterprise and focus on recovering those services within a specific timeframe.

Key Challenges in Network Recovery:

Traditional network security methods, such as firewalls, Virtual Private Networks (VPNs), and segmentation, often fall short in providing the necessary level of cyber resilience to an enterprise.

These controls have operational difficulties and conceptual flaws that make them ineffective in preventing unauthorized access attempts.

​ Some of the challenges associated with these traditional methods include:

  1. Segmentation: While network segmentation aims to enhance security by dividing the network into smaller segments, it often fails to prevent adversaries from traversing segments due to overly permissive gaps in access control. 
  2. Firewalls: Firewalls, although fundamental to network security, can be complex to manage and may inadvertently allow undesirable traffic, facilitating lateral movement within networks.
    ​VPNs: VPNs, commonly used for remote access, can become a common entry point for adversaries. Once authenticated, users are granted access to the trusted network, exposing sensitive applications and data. Recent zero-day attacks targeting major VPN vendors have highlighted the vulnerability of this access point.

Innovative Approaches to Network Recovery:

To overcome the deficiencies of traditional network security methods, organizations are adopting innovative approaches like Zero Trust with a Secure Service Edge (SSE) architecture.

This modern architectural approach focuses on Zero Trust Network Access, delivered through SSE, to establish and maintain trust and control in the network.

By replacing VPNs, firewalls, and network segments with an SSE solution, organizations can recover their networks faster and enhance overall security.

Long-term Resilience and Monitoring

Zero Trust Architecture:

Implementing a Zero Trust architecture is a key strategy for long-term resilience against ransomware. Deloitte utilizes Zscaler's Zero Trust Exchange(™), a security framework that operates on the principle of 'never trust, always verify '. This ensures that trust is never assumed, and access is continually verified based on user identity, device posture, and contextual factors. This approach significantly reduces the attack surface.

Continuous Monitoring:

Ongoing monitoring is critical to detecting and responding to threats in real-time. Deloitte, in partnership with Zscaler, takes a proactive approach, utilizing Zscaler's advanced threat intelligence and analytics to monitor network traffic and user behavior continuously. This proactive approach helps to identify suspicious activity before it can escalate into a full-blown attack, ensuring your business is secure and protected.

Incident Response Plan:

It is crucial to have a robust incident response plan in place for rapid recovery from future attacks. Deloitte assists organizations in developing and regularly updating their incident response plans. This involves conducting a thorough risk assessment, identifying potential threats and vulnerabilities, and outlining the steps to be taken in the event of an attack. Zscaler's security capabilities are integrated into these plans, ensuring all stakeholders are ready to respond quickly and effectively during another ransomware attack.

Cyber Insurance Advisory:

Deloitte offers guidance on cyber insurance to help organizations minimize the financial impact of ransomware attacks. They ensure that policies cover various scenarios and include provisions for working with cybersecurity firms like Zscaler.

Conclusion:

Enterprise Recovery is a critical process for organizations to regain trust and control in their networks after a major breach. Traditional network security methods often fall short in providing the necessary resilience and speed required for recovery. By adopting innovative approaches like Zero Trust with SSE architecture, organizations can expedite the recovery process, enhance network security, and ensure a safer and more resilient future.

Integrating Zscaler's advanced security capabilities with Deloitte's deep cybersecurity knowledge, organizations can recover from ransomware attacks and build a robust defense against future threats, leaving you with a sense of relief.
