E-Handbook: Threat detection and response demands proactive stance Article 1 of 4

As cyberthreats evolve, so must enterprise defenses

Cyberthreats are more sophisticated than ever, with attacks proliferating at alarming rates and nefarious actors employing stronger techniques to evade detection. Add in the ever-expanding attack surface, and the issue is further exacerbated.

Beyond the threats, security teams face an onslaught of alerts from a growing number of tools that are designed to help them. To that end, teams ignore nearly 50% of security alerts because it's unrealistic to investigate every alert, according to a 2020 AT&T survey.

Simply put, mechanisms that were helpful in the past can't adequately counter the surging threat landscape. For too long, reactive security measures have been the norm, but a proactive approach is required to stay ahead of attackers.

This sea change in methodology means security teams must learn about and assess a slew of acronyms, including endpoint detection and response (EDR), network detection and response (NDR), managed detection and response (MDR) and, most recently, extended detection and response (XDR). Also required are new methods for addressing and preventing alert fatigue, such as using AI or adopting cloud-based services.

This handbook examines the current state of threat detection and response, and where EDR, NDR, MDR and XDR fit in. Then, dive into XDR to uncover how its greater context and visibility help security teams quickly react to and reduce the effects of security events. Finally, read about alert fatigue and how to avoid its potential consequences.

Don't let the growing volume and sophistication of threats and malicious actors outpace the level of protection your organization's security tools provide. It's time to move into the next era of threat detection and response technologies and techniques.
