How Cyber Fusion Minimizes the Risk of Ransomware Attacks?

Posted on: May 04, 2022
In 2021, an increase in sophisticated, high-impact ransomware incidents was observed against critical infrastructure organizations across the globe. The cybersecurity authorities across the US, UK, and Australia discovered tactics and techniques that demonstrate the ransomware threat actors’ increasing technological sophistication and growing ransomware threat to organizations globally.
Modern-day organizations need modern-day solutions like cyber fusion to reduce the risk of ransomware impact.
Ransomware Attacks can be Reduced with Cyber Fusion
Typically, ransomware operators design their malware to spread laterally across an organization’s network in an attempt to impact and encrypt critical data. Cyber fusion has proven to be an effective solution for containing such attacks in their early stages. To contain a ransomware attack, organizations need operationalization of threat intelligence across detection, analysis, and response technologies. With cyber fusion, organizations go beyond the bounds in terms of threat intelligence operationalization and automated collaborative response. It helps them collate the threat intelligence gathered from various internal and external sources, enhancing threat detection and response workflows. Furthermore, cyber fusion leverages security orchestration, automation, and response (SOAR) capabilities to drive various security operations using disparate tools and technologies. This spares the security analysts from performing manual tasks involved in analyzing and mitigating the ransomware attack, providing them a smarter and faster response to it. The automated cross-functional workflows of a cyber fusion solution helps address a ransomware attack with little to no human intervention. Therefore, security analysts can focus on conducting in-depth ransomware investigations. Moreover, a true cyber fusion solution comes with advanced automation including low code ransomware response playbook that allows SOC teams to quickly trigger threat investigations with data enrichment and correlation followed up with machine speed response against the ransomware attacks bringing down the overall mean time to detect (MTTD), mean time to respond (MTTR), and mean time to contain (MTTC). Here’s how the ransomware response playbook performs the following tasks:
As soon as an alert is triggered from an SIEM tool, an incident is automatically created for investigation in a threat response module of the cyber fusion center (CFC) using an automation playbook.
Incident Correlation and Enrichment
Once the investigation starts, the CFC fetches both the host and user information for data correlation. To connect the dots between different threat elements, the CFC starts correlation of the collected information with multiple threat parameters spanning from malware, vulnerability, threat actors, and past incidents while simultaneously enriching the threat data using an in-built TIP module.
After the initial triage, if the ransomware alert is found to be genuine, the impact and scope of the ransomware attack is determined. Critical actions are performed to stop the spread of ransomware across other systems on the network. The actions include blocking the malicious hash on the endpoint detection and response (EDR) tool and quarantining the impacted user asset using the EDR tool.
Response and Remediation
For complete threat response, the automated playbook performs antivirus scan, security control checks, and retrospective search on SIEM tools. Security teams can perform an antivirus scan on the affected to contain the infection and stop it from further spread. Subsequently, the threat response module of the cyber fusion center is queried to check for the affected user’s patch history and the SIEM tool is checked for other affected assets.
Advantages of Using Cyber Fusion
There are different security functions and cyber fusion combines all of them into a single unit in an integrated and collaborative environment. Besides this key advantage, there are other benefits that cyber fusion provides to security teams.
Early Detection and Containment
A ransomware infection spreads tremendously fast across a network of connected devices. Cyber fusion solutions automate threat response to hold the malware at bay at machine speed instead of relying on slower, manual processes. This reduces the overall MTTD, MTTR, and MTTC.
Complete Threat Visibility
Threat visibility is an important component of a cybersecurity strategy. Cyber fusion facilitates automated incident analysis and response and connects the dots between ransomware, malware, vulnerabilities, and threat actors in real-time to provide end-to-end threat visibility.
Standardized Response Process
Cyber fusion enables faster response delivery through automated playbooks designed specially to counter ransomware attacks. Furthermore, security teams can custom edit the playbooks to contextualize the response to their security and network infrastructure.
Simplified Security Governance
An automated ransomware response playbook streamlines the governance of security teams to handle the ransomware response process with limited resources.
Ransomware attacks can cost organizations millions of dollars, impacting reputation and reliability in the long run. Having a cyber fusion-driven strategy in place can help SOC teams respond faster to ransomware attacks and take necessary measures.
