In our journey through the landscape of modern threat detection, it’s imperative to shed light on the areas where EDR and XDR solutions face hurdles, necessitating augmentation. While these technologies excel in many aspects, it’s vital to acknowledge their limitations, particularly in the realm of false positives.
False Positives as the main challenge
In the unending quest to fortify digital fortresses against relentless cyber threats, the persistent specter of false positives casts a shadow. A comprehensive analysis spanning 2015 to 2018 underscores the stark reality—organizations grappled with an average loss of 395 hours weekly due to false positives. This financial hemorrhage amounted to a staggering $25,000 per week, culminating in an annual toll of nearly $1.2 million.
Diving deeper into the genesis of false positives reveals a multifaceted landscape. Introducing a new application, deploying a software update, or even detecting seemingly irregular user behavior can trigger a response from the system, often labeled as suspicious. This behavior-centric reaction unfailingly generates false alerts, entailing a costly waste of invaluable time and resources.
Mitigating the False Positive problem:
To mitigate the impact of false positives, strategic measures can be employed. Leveraging preloaded application exceptions and categorizing machines based on behavior patterns, organizations can progressively diminish the recurrence of false alarms. This calculated approach aids in refining the precision of these systems over time.
The Ongoing Struggle Against Evasion:
While EDR and XDR solutions undoubtedly surpass traditional antivirus tools, the ever-evolving cyber threat landscape poses a persistent challenge. Malware authors are unceasingly seeking ways to outsmart these sophisticated technologies. Take, for instance, the emergence of techniques like Mockingjay, adept at eluding EDR hooks through DLL injection hollowing processes.
As we delve into the intricacies of EDR and XDR deployments, it becomes apparent that even advanced technologies face obstacles. The battle against false positives and evasion tactics necessitates holistic comprehension and a multi-pronged strategy.
