Cyber threats are ever-evolving, which calls for organizations to implement robust security solutions that will effectively detect and cater to sophisticated attacks. Extended Detection and Response (XDR) is emerging as a very important leap forward in detection and response to threats. At NetWitness, it provides cutting-edge benefits in the cybersecurity scene for modern organizations.

To detect, analyze, and respond to potential threats in real-time is the real deal. XDR security arena covers network, endpoint, email security domains, and cloud. It is a more advanced version of endpoint detection and response (EDR). While EDR’s focus is on endpoints, XDR dwells on numerous security control points.

Operating as a software as a service (SaaS), it provides all-inclusive security by merging tooling. If you are in need of a complete solution that fully takes care of the complexity of the modern security landscape, look no further, as XDR threat detection is the one. Compared to conventional security approaches tied to a specific layer of the security environment, they produce more volumes of alerts, take more time to investigate and provide a decision, and require more maintenance and management.

Problems That XDR Exclusively Solve

Modern threats continue to expand in complexity while many cybersecurity solutions are slow to evolve. Ransomware and zero-day attacks are some of the sophisticated threats that continue to increase in volume and have proved to be very costly. This calls for a proactive approach to implementing cybersecurity policy that includes prevention, detection, and response.

Holistic Approach to Complex Attacks

Although endpoint protection is the first layer of defense for companies, XDR identifies and stops threats on the endpoint automatically and instantly, saves time, and prevents adjacent contagion. This helps a security analyst team to readily see which threats have been prevented, saving them ample effort comparing and validating low-value threats.

Consequently, extended detection and response allow security operations to focus on high-priority and critical threats. Imagine security analysts spending about half an hour investigating every threat using incongruent security tools. They have to hand-stitch data and try between tools.

With XDR, the job becomes very simple, centralizing security events between manifold security controls to deliver a holistic approach to how complex attacks progress across a kill chain. By combining weak signals from various sources into stronger signals, it pinpoints known and unknown threats altogether.

Data With Context

Data is meaningless without proper context. Extended detection and response is an integrated platform that correlates data. With greater context of data, XDR avoids false positives and allows security operations to focus on threats that really exist. The integration and correlation is a smart job for security teams to not easily get lost in lots of unfeasible alerts.

How XDR Works

Imagine a massive connection of security cameras for a system that monitors different parts of a building. XDR is compared to the central security office that all camera feeds come to. The security officer is XDR, watching all screens concurrently to identify any suspicious activity across the whole building.

Collects Data

Extended detection and response works by collecting data across multiple sources within a company’s network. This data comes from computers and servers, email communications, cloud-hosted applications, and network traffic.

Detects a Threat

This data is analyzed under the platform’s microscope using complex techniques and tools such as artificial intelligence and machine learning. Layers of collected information are scabbed for any signs of suspicious activity.

Complex Analysis of Data

Upon detection of a threat, this operation doesn’t stop there. An analysis is dug deeper to know the nature of the information security breach, where it originated from, and the potential impact on the system.

Response

Once analysis is finished and the threat has been positively identified, there is no wasting time. XDR automatically starts countermeasures to keep it from spreading further and neutralizes it.

Threat Intelligence

After the whole experience, machine learning initiates to adapt the defense mechanism to protect against parallel breaches in the future. The effectiveness of the system is robust due to the continuous learning process over time.

What Are XDR Key Features?

XDR features multiple consolidation tools for preventing, detecting, and responding to cybersecurity cracks. These integrated tools provide a highly improved environment for the prevention and detection of threats, better analysis, and quick remedy. Not all extended detection and response systems are the same, as every vendor offers different integrated tools. Some of the key features that every XDR solution offers include:

  • Endpoint detection and response (EDR)
  • Secure email gateways (SEG)
  • Endpoint protection platforms (EPP)
  • Cloud access security brokers (CASB)
  • Network traffic analysis (NTA)
  • Data loss prevention (DLP)
  • Network firewalls, intrusion detection and prevention systems (IDPS), and
  • Threat intelligence

The seamless combinations of tools are premeditated to prevent threats but also detect, analyze, and tranquilize them. Leveraging the numerous integrated tools to impeccably gather and assemble telemetry across the system. Data is collected across networks, endpoints, cloud, servers, identity, and access management solutions.

Using artificial intelligence, operation of detection, correlation, and contextualization are prioritized data breach alerts, including using behavioral analysis and machine learning (ML). Overall, the gravity of alerts is improved to do away with false positives.

The Benefits of Using XDR in Organizations

Extended detection and response helps organizations more effectively tackle sophisticated and emerging threats. Today, many SOCs and security teams confidently rely on a daily basis on XDR in addressing the key cybersecurity challenges they face in the modern era.

Consolidated and Accurate Alerts

Companies are overwhelmed when an IT security solution deployed responds with irrelevant alerts and false positives, which also leads to the most critical alerts going undetected. Thanks to the complex landscape of coordination and context shared between interconnected tools and features, alerts are solid and accurate.

From the very beginning, alerts are combined and correlated to authenticate their relevance and prevent false positives. Therefore, signals of malware content are accurately determined and events truly contextualized.

Automation for Improved Productivity

The automation component in XDR goes a long way to help boost and secure productivity in companies. It is the best way to manage increased volumes of security alerts, helping determine true from false positives. Alerts are prioritized based on the level of threat and severity. Using artificial intelligence and machine learning, data breaches are automatically solved.

XDR is enabling SOCs and IT security teams to effectively deter and remove sophisticated data breaches and efficiently respond to security incidences. This is an upgrade from cybersecurity solutions like security information and event management (SIEM), EDR, and security orchestration, automation, and response (SOAR).

Are you struggling to address an overwhelming volume of security alerts and efficiently and effectively addressing data breaches and concerns? XDR threat detection from NetWitness is the ultimate solution for your organization’s needs.
