Security is more critical than ever. Over the last few years, Endpoint Detection and Response (EDR) has become an important solution for identifying attacks on corporate networks. Endpoint Detection and Response is great for small business security because it can provide them with the information and means necessary to contain a security breach.

How Does Endpoint Detection and Response Work?

Let's look at a worst case scenario. An attacker breaks into a network by exploiting a security vulnerability on an endpoint within an organization's network (vulnerable application/operating system combination). This is where EDR software kicks in.

As soon as the entry point is identified by EDR software, it immediately sends an alert to designated employees in order to alert them of the breach, and prevents the effect from happening.

• The agent records details such as location, hardware information and configuration settings, for future forensic analysis by IT support.
• EDR servers are able to monitor applications running on endpoints for any unusual activity and, provide additional security measures to prevent system infection by malware propagated from an infected endpoint.
• EDR works even when an attack has occurred. The tool will detect the breach and within seconds of detection, isolate any affected machines and quarantine the threat.
• EDR software logs unauthorized access and file manipulation attempt on monitored endpoints for further analysis and investigation.
• EDR servers record enhanced security audit logs that can be used for forensic purposes to assess damage control measures, and also help in the detection of breaches through post-incident forensics. This means that information is recorded at the endpoint, including who accessed the system, what files were modified or deleted, and information about all processes running at the time.
• EDR software can provide alerts when machines connect to unknown networks or access the internet via a proxy server. These EDR tools can be configured so that any unauthorized connections would result in an automatic quarantine of the device pending remediation actions, including remote data wipe.

EDR software offers a wide array of features such as early warning, event management, incident response, threat management, and preventive measures. This means that EDR software applications give companies real security benefits.

What Happens When An Attack Occurs?

EDR software can be configured to initiate a strategy when a threat is detected, which may include:

- Automated containment of the compromised machine by limiting its access to local resources and even shutting it down, protecting sensitive data.

- Alert support analysts to begin further investigation and collaboration with affected enterprise stakeholders from emerging threats.

Gathering Intelligence

EDR software can be used to gather intelligence about the threat, enabling better identification of that threat, and related malicious behavior. EDR can generate information that may help determine whether the compromise is part of a larger cybercriminal campaign.

EDR can detect a large number of entry and execution events that otherwise would be impossible for human support analysts to detect in real time.

Preparing Now For Tomorrow

Furthermore, EDR can provide analysts with the ability to make informed decisions about how best to respond to attacks-from the moment they first occur through subsequent phases of their life cycle.

Finally, a dedicated threat response team is part of the solution- a Security Operations Center (SOC) can analyze and help eliminating threats once the EDR software contains it.

What Can Endpoint Detection and Response Do?

Endpoint Detection and Response is designed to monitor what is happening on endpoints (computers, handheld devices, etc.) It works by collecting intelligence about malicious and benign events, such as:

• EDR can detect the execution of certain code (malware) much earlier than normal detection methods.
• EDR identifies not just whether there is malware present, but also what type of malware was detected. Malicious software is detected and quarantined, and remediation can occur before any damage is done to the enterprise.
• EDR software removes malware from endpoint computers, and clean infected systems of malicious code.

Importantly, EDR software operates silently in the background, with minimal impact on employee productivity or performance.

Real Time Data Collection

EDR data originates on the endpoint-in real time-rather than after the fact.

EDR solutions detect and record suspicious behavior that may indicate malware activity on a protected system. It collects data on both normal and abnormal events, providing a window into what is happening in real time across all endpoints.

EDR automatically detects malicious activity via software agents that monitor processes, files, registry changes, and so on. It automates the investigation of suspicious activity, reducing time to detect and respond to incidents.

It's able to do this because EDR security systems hook deeply into a computer's operating system and its applications, allowing the software to know exactly what information is being communicated; when it's being accessed; and how that data could be corrupted or otherwise compromised as part of an attack.

Legal Protection

It also provides better evidence for prosecution in case your system is breached after all. EDR software can gather hundreds or thousands of system details in near real-time from which investigators can derive patterns and behaviors, find anomalies, spot breaches sooner, and significantly reduce their time to detection when they do occur.

This makes EDR an ideal tool for finding automated attacks known as Advanced Persistent Threats (APTs) that very carefully hide within corporate networks before gradually working toward long-term goals such as data exfiltration. EDR enables organizations to detect these types of incidents much earlier in the attack lifecycle than would otherwise be possible with traditional methods.

Threat Identification

EDR solutions allow organizations to identify threats in real time before they cause damage.

When a threat is detected, EDR solutions can manage and respond automatically by alerting IT professionals, blocking attacks, and collecting forensic evidence of the attack. EDR solutions are invaluable for preventing data loss in your organization and for quickly mitigating damage after an attack. Infrastructure and devices are protected.

Once an attack has been detected, EDR solutions can help in the recovery process by providing real-time details on an attack's origin, whether it was successful and what information has been compromised. Your support team will have visibility on what happened, an essential element in threat response.

Is It Expensive?

No! EDR is not exclusively for large enterprises. EDR solutions are affordable, and yearly subscriptions are certainly much less costly than a data breach.

In fact, EDR is one of the most cost-effective ways to defend against cyber attacks, which can be very costly, and even cripple or destroy a small business. EDR solution providers have developed lower pricing for small businesses, which helps eliminate EDR's traditionally high price tag.

EDR solutions are available in all sizes and price points. EDR solutions can address an organization's needs no matter its size, with many options available in cloud or on-premises deployments.

Isn't Antivirus Software Enough?

Antivirus software requires an infected system to be scanned continuously for the presence of malicious code. This runs the hard drive constantly and drags down the system.

EDR technology is far more efficient and proactive than antivirus software: EDR will only scan a computer once, after which time it operates silently in the background without any further impact on performance, monitoring for suspicious processes rather than constantly just scanning the hard drive for threats.

Prevention Is Better Than The Cure

That means that antivirus software is reactive, while EDR technology works proactively. EDR is alerted by suspicious behavior that antivirus software wouldn't detect, and immediately intervenes to prevent data compromise.

EDR's focus on prevention rather than detection makes it a more cost-effective solution - after all, prevention is better than cure! Whether it's ransomware encrypting files or hackers stealing sensitive data, EDR stops threats before they cause damage.

Reducing System Overhead

That's why EDR detection techniques reduce overhead on network resources such as bandwidth and processor power. EDR can detect malware that antivirus software might not be able to detect because of fast-mutating or polymorphic malware (e.g., rootkits).

Furthermore, EDR ensures that all malware has been removed before allowing computers to connect to corporate networks again, thus reducing reinfection rates significantly from traditional remediation approaches using AV scanning alone.

EDR And Your Business

EDR solutions employ security intelligence that monitors your network and applications 24/7 for signs of cyber threats, eliminating potential threats and filling security gaps.

Advanced attacks and zero day attacks can be difficult for normal security tools to spot. EDR provides real time analysis of system behaviors means that EDR can handle advanced threats and even zero day threats because it monitors system and network behavior rather than looking for specific viral signatures.

Small Business Solutions

EDR solutions are especially helpful to organizations with limited IT resources or security teams where problems can be easily overlooked. A small company's security team can easily be overwhelmed without good tools, but EDR will enable your company to maintain a good security posture without investing unreasonable amounts of time.

Endpoint threat detection and response is an important aspect to cybersecurity. Businesses need the capability to handle an incoming security incident without human intervention. A prompt response is critical. Companies need to be able to protect critical devices and infrastructure, and employing a strong endpoint protection solution is a critical tool in the toolbox to protect your business and your business's data.
