Protect Your Data Beyond the Endpoints with XDR

  • QUANTUM SECURITY BLOG

For years, organisations have relied solely on Security Incidents and Events Management (SIEM), antivirus technologies (EPP), and Endpoint Detection and Response (EDR) as the cornerstone of their cybersecurity strategy. However, as more and more businesses are going through a digital transformation, businesses are increasing their activities across multiple security layers. 

On the other hand, cybersecurity threats have been on the rise, and on a more concerning note, the strategies applied by the perpetrators are more sophisticated and increasing in their complexity over time. Stealthy threats have been known to go undetected, hiding between the silos of each security layer. Once a perpetrator managed to breach into the silos, it is not impossible for them to move laterally and expose other weak points within your own digital infrastructure. Even if security analysts managed to triage and disconnect threat viewpoints, response times to such incidents have subsequently continued to increase. There is a looming question for everyone in the industry. Can businesses continue to rely on these strategies in the long term?

As this question brings organisations into a search for more robust security solutions, Extended Detection and Response (XDR) emerges as a leading alternative. Known as cross-layered detection and response, XDR has the capability to correlate data across multiple security layers – email, endpoint, server, cloud workloads, and network. This is different from other security approaches that only protect the endpoints, leaving other layers vulnerable. In the landscape where most business activities are increasing online, the stakes are too high to ignore the risks on other security layers. 

On top of its cross-layer protection, XDR threat detection capability is based on AI. It is capable of collecting together a series of lower-confidence activities into a higher-confidence event, surfacing fewer, prioritised alerts for Information Security personnel to take action. XDR also contrasts, collects, and provides access to the fullest length of your activity data, which includes detections, telemetry, metadata, netflow, etc. In cases of potential breach, the automation brought by XDR has allowed for a more focused, targeted, and quicker response by security experts.

Implementing XDR into your security strategy will be a long-term investment. To some organisation, it may constitute a major shift from the existing security strategy. You will need to ensure three important aspects. First, your organisation or the security vendor your company hires has the solutions across the entire network, including cloud, gateway (email and web), network, server, endpoint (includes mobile), and IoT/IIoT. They should be able to conduct threat intelligence and data analysis, including third-party threat intelligence such as CERT, ISAC, and ISAO feeds. Lastly, your security analysts have the expertise in AI and machine learning, as they will need to correlate various threat factors that are identified by the automation.

Advanced security approaches should be complemented by a knowledgeable team of cybersecurity experts.
