Endpoint Detection and Response (EDR)
What is EDR?
An endpoint is a device that shares information with other devices and end users over a network i.e. desktops, laptops, and mobile devices. Endpoint Detection and Response (EDR) software is used to provide clearer visibility into endpoint activities while also offering threat hunting and remediation services. Those core functions are what led Gartner's Anton Chuvakin to first coin the term 'EDR' in 2013. Vhuvakin noted that "this name reflects the endpoint (as opposed to the network), threats (as opposed to just malware and officially declared incidents) and tools' primary usage for both detection and incident response."
The Key Components EDR Security
What is EDR and what are the components that make up a successful EDR program? EDR security acts as a layer of protection that complements an Endpoint Protection Platform (EPP). EDR is proactive in its nature as it allows security operations center (SOC) teams and security professionals to identify, take action against, and investigate threats. Here are the critical components that make up EDR security:
Data Collection and Aggregation
The data collected from the continuous monitoring of endpoints by an EDR solution is what enables security teams to quickly identify and respond to threats. This data includes the performance of endpoints, files download, transfers made to other endpoints, any changes to the configuration, overall user behavior, and more. This data is usually stored and hosted in the cloud.
An EDR system's ability to analyze large amounts of data instantaneously is enabled by the use of artificial intelligence (AI) and machine learning (ML). This use of AI and ML allows the EDR to identify patterns and make inferences on incoming data. Once analyzed, the EDR security system will summarize the critical points and offer the results to its management team or security professionals.
Automated Threat Detection & Response
A core function of the EDR is automation. Automation allows for the detection and immediate response to threats based on the behavior it has learned over time or what has been defined by the security team. The AI/ML algorithms that make them up can also do their own threat detecting by comparing real-time data to historical data and established baselines
Once a cyber threat is identified, an EDR cyber security system makes way for a SOC team or security analyst to perform investigative actions. Once the analyst investigates a threat, they do things like remove malicious files left on the endpoint, fix harmed application files, or apply necessary updates or patches.
The Importance of Endpoint Detection and Response
The use of a Next-Generation Antivirus (NGAV) system coupled with EDR security is paramount. According to research from IDC, 70% of successful cybersecurity breaches originate on endpoint devices. While many large enterprises have adopted EPP and EDR technology since the turn of the decade, the technology is highly underutilized by home users.
In today's digital world, home users from all around the globe are spending increasing amounts of time online. Whether it be for online shopping, gaming, working from home, attending online classes, streaming content, or any other reason, home users face a seemingly endless barrage of cyber threats.
The benefits of EDR tools and products are clear: users are highly protected from next-generation cyber threats and can use their devices with confidence. Because EDR provides more visibility into what's happening on an endpoint in real-time, it enables better threat hunting by researchers and automatic threat remediation by the system itself.
EDR Cyber Security vs. Endpoint Protection
Endpoint Detection and Response differ from Endpoint Protection Platforms (EPP). Endpoint Protection is the cybersecurity approach to defending endpoints from cyber threats. EPP's such as RAV Endpoint Protection utilizes a Next-Generation Antivirus (NGAV) to address malware from every angle. The aim of an Endpoint Detection and Response solution is to combine real-time monitoring of endpoints, in order to identify a device's weakest intrusion points and learn how malware operates. The data collected from the continuous monitoring of endpoints can then enable security teams to quickly identify and respond to threats.
EDR Programs vs. Antivirus
EDR software and EDR tools work hand-in-hand to complement the protection given by Next-Generation Antivirus (NGAV) software. Traditionally, Antivirus programs work to stop a cyber attack and intercept them from breaching a device or its network. Once a device or network is breached, however, the Antivirus or Endpoint Protection can no longer be of service. EDR serves as a further layer of protection that can recognize and contain cyber threats which infiltrate the Endpoint Protection or Antivirus defense.
EDR vs. XDR
Endpoint Detection and Response (EDR) and Extended Detection and Response (XDR) were both developed to deliver automated threat detection and response, with threat intelligence capabilties. XDR, however, is designed to go further than EDR by securing a large network instead of securing only an endpoint. XDR, typically a resource used by large enterprises or organizations, can be used to easily integrate security across an IT department's entire infrastructure. Thus making it more manageable for an enterprise's SOC team to control the security of all of the endpoints used throughout the organization. Because the XDR will aggregate data from the entire network, it has the ability to detect highly advanced and widely distributed attacks.
ReasonLabs' RAV Managed EDR
RAV EDR is an industry-leading managed EDR system that is built to enterprise-level standards and designed for use by families and individuals at home. The RAV Endpoint Detection and Response system combines leading detection technology with ReasonLabs' machine learning engine, using prevention methods from its Threat Intelligence Center.
RAV EDR functions in three steps:
- RAV Detection: By scanning and learning how malware operates, RAV EDR can identify a device's weakest intrusion points
- 24/7 Endpoint Response: RAV EDR will detect and respond around the clock by using all layers of its protection
- RAV Response: RAV EDR attacks threats and takes care of security breaches by concisely deleting viruses to protect a device.
Using Endpoint Detection and Response, ReasonLabs can provide a complete line of events that led to a cyber threat being detected on an endpoint. A complete picture can reveal a suspicious origin making it possible to construct a much more precise diagnosis.
