Question 1

What is endpoint detection and response (EDR) software?

Accepted Answer

EDR software is used to help companies identify and remediate threats related to network-connected endpoints. EDR solutions inform security professionals of vulnerable or infected endpoints and guide them through the remediation process. After incidents have been resolved, EDR tools help teams investigate issues and the vulnerable components that allow an endpoint to become compromised. 
 Continuous monitoring is one of the core capabilities of endpoint detection technologies. These monitoring features provide complete and continuous visibility across a company’s network-connected endpoints. Individuals can monitor behaviors, vulnerabilities, and activity for abnormalities. When abnormalities are identified, the detection portion of EDR technology transitions to the response portion. 
 Endpoint response begins with alerting and containment. Security professionals are alerted of threats present to their systems and isolate potentially compromised endpoints from further network access; this helps prevent one infected endpoint from becoming hundreds. Once systems are properly organized to contain malware and threat actors, security teams can work to remove malware and prevent future access from actors to endpoint devices. 
 EDR platforms store threat data related to security incidents, improving a team's ability to defend against threats in the future by helping them identify root causes and threat actors. Additionally, zero-day exploits may be identified, and other vulnerabilities may be remediated as a result. This will help prevent third-party privilege escalation, malware injection, and unapproved endpoint control from occurring in the future. Some EDR products provide machine learning capabilities to analyze events, improve threat hunting, and reduce false positives by automating protection and remediation processes.

Remediate present threats to endpoints
Investigate incidents to identify causes
Contain threats and restrict access to other endpoints or networks

Question 3

Why use endpoint detection and response solutions?

Accepted Answer

Endpoints are some of the most vulnerable components of a business' network structure. One vulnerable endpoint could cause a company’s entire network, databases, and sensitive information to become exposed or stolen. EDR systems will help secure individual endpoints, detect issues as they arise, and contain threats that make their way beyond traditional security structures. 
 Endpoint protection is even more relevant considering the growing popularity of bring-your-own-device (BYOD) policies. When employees are in complete control over downloads, applications, and updates, security must be a priority. Every day professionals are not the most security-savvy individuals and may unintentionally compromise their devices or put business information at risk. 
 Zero-day threats—While traditional prevention tools such as antivirus software or firewall technology are helpful as the first line of defense, zero-day threats are bound to occur. The nature of these threats means they have yet to be discovered and, therefore, cannot be defended against. EDR solutions will help identify new threats as they arise and remediate them before damage occurs. 
 Visibility and control—Continuous monitoring and endpoint visibility help defend against traditional malware and sophisticated threats. Monitoring can help identify known threats as they arise and detect minute details that indicate the presence of advanced threats. Hackers are always developing new ways to enter networks undetected through fileless malware or malicious code injection. Monitoring capabilities will improve a team’s ability to detect anomalies caused by outside actors and threats. 
 Analysis and deterrence — EDR software improves a security organization’s ability to review the data associated with security events, data breaches, and network attacks. The data collected from these events can be reviewed back to the initial onset and used to identify the vulnerability or exploit used. Once identified, security teams and software developers can work collectively to resolve flaws and prevent similar attacks from occurring in the future.
