Infosys Uses Cortex XSIAM to Revolutionize Your SOC

As organizations continue to embrace new technologies and digital business models, cybercriminals are hardly sitting on their hands. Threats are growing in frequency, impact and sophistication while traditional security technology can’t keep up. Infosys believes that enterprises must adopt a proactive cybersecurity strategy to prevent, detect and respond to threats while optimizing the total cost of ownership. The Infosys partnership with Palo Alto Networks helps secure complex and mission-critical environments by incorporating an evolving portfolio of solutions into managed services. Cortex XSIAM (or extended security intelligence and automation management) by Palo Alto Networks advances this mission to modernize security operations.

Infosys offers a managed version of Cortex XSIAM, which harnesses the power of machine intelligence and automation to improve security outcomes and transform the manual SecOps model. This eliminates the complexity of multiple disparate tools while simplifying and standardizing security processes to see value from the beginning with transparent cost predictability.

Understanding the Old SIEM Approach

To understand the impact and improvements offered by Cortex XSIAM, it helps to see how we got here. Traditional SOCs run on a multitude of security solutions, which can result in feature overlap and vulnerability gaps. Worst of all, this flood of alerts keeps security ops teams from quickly prioritizing the biggest threats. To manage these challenges, security operations (SecOps) teams need to use a variety of different tools:

• SIEM for log management, alerting and reporting.
• Endpoint detection and response (EDR) to gather telemetry from multiple endpoint sources.
• Attack surface management (ASM) to provide asset discovery, vulnerability assessment and risk management.
• Security orchestration, automation and response (SOAR) to automate threat response via prebuilt playbooks.
• Threat hunting, which uses various products to proactively find signs of intrusion across the infrastructure.

The problem is that today’s expanded enterprise attack surface generates much more security data than ever before. Network, endpoint, identity and cloud data remain in separate systems, while only a subset of logs (but a flood of alerts) goes to the SIEM. As a result, SOC analysts must manually analyze data to triage alerts and take effective action. But, it’s easy for them to miss lurking threats.

In the meantime, security engineers struggle to integrate new data streams and create new detection rules and playbooks while security architects work to integrate the latest new point product. Add this to the current security skills shortage and the results are predictable: alert fatigue, slow investigations and attackers who hide in networks for months.

How Infosys and Cortex XSIAM Solve the Challenge

Infosys helps clients standardize, simplify and transform their security technology reducing costs while elevating security posture. As a cloud-delivered, integrated SOC platform that unifies key SOC functions into a single, integrated solution, XSIAM is a great fit for this model. It provides customers with best-in-breed security together with Infosys’ deep expertise and capabilities.

XSIAM uses artificial intelligence (AI) and machine learning (ML) to reduce billions of events to a few incidents. These are further automated for rapid action and defense in the face of potential threats. With SOAR capabilities built in, AI and ML-powered security playbooks minimize human intervention by detecting stealthy threats. XSIAM also leverages behavior analytics correlated with EDR and external intelligence, so the SOC team can contain internal and external threats in seconds through automated action.

Together with Infosys, Cortex XSIAM will revolutionize clients’ SOC team’s critical capabilities:

• XSIAM provides a unified detection and prevention approach combining capabilities from EPP, EDR, SIEM, ASM and SOAR technologies. This ensures threats are automatically blocked and telemetry is automatically correlated for threat detection.
• Uncover anomalies that traditional detection mechanisms would have overlooked by applying AI-generated hypotheses to collected data.
• Integrate telemetry from any source to unify security operations across any hybrid IT architecture and collect gigabytes of data from logs and user devices.
• Add new data sources using a streamlined data onboarding process. An extended data model normalizes and correlates your data for rapid access.
• Detect advanced threats with precision, and simplify investigations with endpoint, network, cloud and identity data that has been automatically stitched together.
• Threat hunting across large interconnected datasets to detect signs of intrusion from a single unified console.
• Investigate incidents swiftly with a full report of every attack, including intelligent alert grouping and collected information about the root cause.
• Focus on the few threats that require human intervention because of embedded automation. This adds detail to alerts, responds to malicious activity, and closes low-risk alerts before they reach the queue.
• Extend detection, monitoring and investigation to the cloud. For many organizations, new cloud systems are not integrated into their SOC. XSIAM is designed to analyze multicloud data and operations, ensuring true enterprise-wide visibility and security operations.
• Benefit from continuous updates from Palo Alto Networks Unit 42 research team (who collect intel from over 85,000 customers), update machine learning detection models, and automatically distribute the latest protections to XSIAM deployments.

Bring Automation to the Next Generation and Revolutionize Your SOC

SecOps teams have too much information to manage in too many silos. They rely heavily on reactive manual human effort after an incident, leading to longer investigation times, missed events and longer dwell times (periods when attackers can lurk in systems undetected).

Infosys, along with Palo Alto Networks Cortex XSIAM, transforms clients’ SecOps to an autonomous SOC platform that fundamentally changes how data, analytics and automation are used across enterprise and cloud security operations.
