How does Cyber Fusion Improve Incident Response?
Posted on: March 04, 2021
It is impossible to manually examine all security alerts, investigate them, and respond to all the incidents. To help address this challenge, the security industry is continuously developing tools and solutions to automate incident response. The modern-day threat landscape demands threat response automation platforms that amalgamate cyber fusion capabilities to respond faster and effectively to incidents, reducing the burden on security teams.
Role of Cyber Fusion in Incident Response
Without any human intervention, security automation powered with cyber fusion accelerates mundane security operations to detect and respond to threats and incidents, helping security teams build a steady defense mechanism. The influence of cyber fusion-driven incident response can be observed while identifying and responding to threats in real-time. From collecting malware intelligence to implementing processes and resolving threats, cyber fusion empowers security teams to effectively manage alerts without manual efforts.
Beefed with cyber fusion, incident response platforms empower not only security teams but SOC managers and CISOs alike. By automating incident response, security teams can channelize their time toward more critical and productive tasks. Without automation, they devote their valuable time to manually sift through multiple security tools looking for alerts that need an actual response. The amount of time spent on gathering routine data subsequently increases their mean time to detect (MTTD) and mean time to respond (MTTR) to threats as it takes longer to distinguish the real threats from the noise. Cyber fusion enables security teams to focus on critical processes and accelerate data aggregation, equipping them with relevant information required for analysis.
Integrating cyber fusion with incident response allows security teams to yield better performances from their teams, building collective defense and enabling them to focus on more productive tasks. Consequently, this leads to improved productivity throughout the security operations (SecOps) team, better KPIs, and reduced security talent turnover rate in security teams.
Before determining what security operations to automate, it is important to first organize existing manual incident response processes into playbooks. This makes an organization’s workflow more predictable, resulting in improved consistency and efficiency. Once processes are organized in a consistent way, it becomes easier to identify the steps and tasks that require automation to accelerate incident response and unburden teams to focus on tasks demanding expertise.
The Need for Cyber Fusion in Incident Response
By offering automated playbooks that seamlessly integrate incident response workflows, cyber fusion empowers security teams to carry out SecOps across different environments—on-premise and cloud—at machine speed, delivering quicker response based on contextual threat data.
Cyber Fusion and Analysis
The advanced cyber fusion capabilities strengthen collaboration between different security teams and provide 360-degree visibility into the adversaries’ behavior to deliver an improved incident response. Security teams can collect and correlate multi-sourced threat intelligence with malware, threat actor, vulnerability, and incident data in real-time to gather contextual intelligence for effective and adaptive incident response. Through advanced correlation and real-time analysis, strategic, tactical, and technical threat intelligence can be collected from disparate sources and operational intelligence can be deduced. Furthermore, cyber fusion-based incident response playbooks help to connect the dots between isolated threats and incidents, establishing hidden threat patterns and accelerating threat actor tracking. It can support frameworks such as MITRE’s ATT&CK, using which threat actor footprints can be identified and tracked by mapping the tactics and techniques against reported incidents.
Integrated Threat Response
In today’s continuously evolving threat landscape, depending on only incident management to respond to all kinds of threats falls short. By adopting a cyber fusion-driven strategy, organizations can establish a more holistic approach toward incident response. Moving beyond incident management, security teams can respond to all types of malware, vulnerabilities, and threat actors by using integrated threat databases. With cyber fusion-powered collaboration between different security teams, incident triage, investigation, and actioning can be managed within an automated response workflow for a 360-degree response.
Security teams can build a single database of vulnerabilities to track, mitigate, and correlate incidents, malware, threat actors, and assets. By tracking and monitoring malware-related activities from a single-window database, the risk of a malware infection can be reduced and detection parameters for indicators of compromise (IOCs) and tactics and techniques can be examined.
Triage and Case Management Workflow
SecOps teams can contextualize and prioritize potential risks in real-time with integrated triage and case management workflows by leveraging cyber fusion technology in incident response. The cyber fusion capabilities allow security teams to manage various related incidents/threats from a single platform by using threat intelligence ingestion and workflow automation to reduce false alarms, noise, and overall MTTR. With streamlined post-detection and incident triage systems powered with data enhancement, intel enrichment, and advanced correlation processes, security teams can reduce false alarms and analyst fatigue.
Advanced Security Orchestration and Automation
Cyber fusion brings together SecOps and intel teams for proactive threat hunting, quicker incident response, and solution development. Security teams can leverage an extensive library of advanced playbooks and automate responses to complex attacks. Incident response playbooks incorporate advanced orchestration and automation capabilities to automate and streamline triage and response by bi-directionally integrating TIPs, SIEM, EDR, IDS/IPS, Firewalls, and other tools. This allows security teams to take response and threat containment steps at machine speed with scope for manual intervention in unconventional situations.
With incident response playbooks, the what, why, and how of security incidents can be deeply analyzed. Cyber fusion enables security teams to embrace a structured process to perform the root cause analysis of incidents with intel enrichment, historical intelligence, and contextual correlations. Moreover, they can improve analyst decision-making, eliminate false positives, and utilize past learnings through incident correlation based on IOCs. Security teams can gain insights into the threat trends and patterns by connecting the dots between vulnerabilities, threat actors, incidents, malware, cost metrics, SLAs, and more.
Action Management and Tracking
Using incident response playbooks, security teams can assign, track and manage threat response and asset management operations. They can assign actions relevant to threats, response operations, mitigation tasks, and track them via efficient task management and action tracking systems. Moreover, SecOps teams can track the learnings from the incidents and asset enhancements, and trace and kick off investigations on threats and resources allocated to the threat response process. Through incident response playbooks, intelligence requirements can be prioritized for intel collectors and analysts for making informed decisions while ensuring all the necessary actions are taken for preventing future attacks.
Benefits of Cyber Fusion-Driven Incident Response
- Improved MTTD and MTTR: Organizations equipped with automated incident response identify and respond faster to threats than those executing manual processes in their incident response. Automation quickly improves an organization’s MTTD and MTTR to security threats by accelerating the process of identifying real incidents from false positives.
- Better and Informed Decisions: Automated incident response not only accelerates the decision-making process during an attack but also ensures that relevant decisions are made when required with the right input of actionable threat intelligence.
- Improved Collaboration: In the event of a security incident, the collaboration between the stakeholders of an organization is vital to control risk and prevent brand reputation. Having an effective cyber fusion-powered incident response plan in place fosters coordinated interactions between an organization’s internal teams as well as its external partners and suppliers.
- Low Operational Costs: Due to automation, security teams no longer have to manually work on time-consuming and unproductive processes of incident response. With the help of automation, they can redirect their valuable man hours to more productive tasks, reducing the running costs of SOCs. Moreover, having an automated incident response plan allows an organization to take strategic actions in the event of any threat incident, limiting its impact on the overall business.
Cyber fusion is the answer to the concerns of security teams about the lack of skilled internal security staff and the threat that can cause damage to their organization’s reputation. Incident response powered with cyber fusion addresses these issues by ensuring security teams tap into the maximum workload potential of their teams and have processes in place that can quickly minimize the impact of a security incident.
