How to Deploy EDR for Ransomware Protection: A 7-Step Guide

Ransomware attacks are more sophisticated than ever, capable of encrypting your critical data and bringing business to a halt. While traditional antivirus is no longer enough, there is a definitive solution: Endpoint Detection and Response (EDR).

This guide will walk you through the exact steps for deploying an EDR solution to effectively combat ransomware. We'll cover everything from initial planning to continuous monitoring, providing a clear roadmap to securing your organization's most vulnerable assets—its endpoints.

Endpoint Detection and Response (EDR) is a cybersecurity solution that continuously monitors devices (endpoints) in real-time to detect and respond automatically to advanced threats like ransomware and malware.

Coined by Gartner, EDR systems go beyond traditional antivirus by collecting and analyzing endpoint data to identify suspicious behavior patterns. This allows security teams to uncover and neutralize threats that might otherwise go unnoticed.

The core functions of an EDR system are:

• Monitor and Collect: Gathers data on events like process creation, registry changes, and network connections from all endpoints.
• Analyze and Detect: Uses behavioral analysis and threat intelligence to identify suspicious activity that indicates an attack.
• Automate Response: Automatically contains threats by isolating compromised endpoints to prevent the attack from spreading.
• Investigate and Remediate: Provides tools and forensic data for security teams to investigate the threat and restore the affected system.

Ransomware attacks have become an increasingly common and dangerous threat, bringing about significant concerns for individuals, businesses, and institutions. The approaches and tactics of these attacks have transformed and upgraded, with emerging threats showcasing the evolution towards more sophisticated methods that aim to inflict maximum damage to users and businesses, with the main purpose of gaining financial benefits.

At the core of ransomware attacks is file encryption, a technique employed by cybercriminals to steal and make critical data inaccessible until a ransom is paid. Even then, there is no guarantee that when the victim pays the ransom, the access to their data will be restored. The most sophisticated attacks use advanced encryption methods, making it challenging and almost impossible for victims to regain control of their files without complying with the attacker's demands.

To mitigate attacks and empower security against these emerging threats, organizations are increasingly turning to finding the best anti-ransomware solutions. These tools are designed not only to detect and prevent ransomware but also to respond quickly when an attack is underway and before the attack has spread. By recognizing the encryption patterns used by attackers, anti-ransomware solutions play a crucial role in thwarting these malicious attempts before significant damage occurs.

One of the emerging threats is the exfiltration of sensitive data through file encryption. Attackers use the fear of data exposure to convince victims to pay the ransom. As organizations are exposed to this type of cyber threat, the need for proactive measures to prevent and mitigate ransomware attacks becomes fundamental.

Regular updates to software and operating systems, combined with using advanced security tools like EDR and regular employee training to raise awareness of phishing attempts, are critical components of a comprehensive cybersecurity strategy available to recognize and intercept ransomware attacks in their early stages.

As we already mentioned, these attacks are extremely dangerous and ruthless. Dealing with such an attack is definitely an unpleasant experience, and it can lead to serious consequences for users and business organizations. If you are not prepared with the proper security measures and tools, you will probably end up with encrypted data.

In the battle against ransomware attacks, the proper weapon is named EDR. With all the tools it provides users, EDR can be named a top-notch endpoint protection service with high-quality security posture that successfully manages to stop these threats on time before it has become too late. Using EDR services not only protects your computer or device from various types of cyber attacks, but it also succeeds in predicting new threats, approaches, and tactics by scanning for suspicious activity before they have reached your endpoints.

EDR is a combination of tools that provide you with complete protection from the stage of real-time monitoring, threat intelligence, threat hunting, and quick response capabilities in order to protect your healthy device environment. This type of security service provides you with a variety of benefits, like mobile device management, which gives you the freedom to change tamper protection mode whenever you need it.

A successful EDR deployment requires careful planning and execution. Follow these seven steps to integrate an EDR solution into your security infrastructure.

Step 1: Identify and Map Your Endpoints Before you begin, inventory all endpoints that require protection. This includes on-premise servers, desktops, remote employee laptops, and cloud-based instances. Understanding your entire environment is crucial for comprehensive coverage.

Step 2: Choose the Right EDR Provider Evaluate EDR vendors based on your specific needs, budget, and existing infrastructure. Look for key features like cloud management, automated response capabilities, and threat intelligence integration. Most providers, including Acronis, offer trial periods to test their services.

Step 3: Develop a Deployment Plan Create a detailed plan that considers your network architecture and any potential conflicts with existing security software (like antivirus or firewalls). Define deployment phases, starting with a small, controlled test group before a full rollout.

Step 4: Test in a Staging Environment Never deploy directly to your entire organization. Install the EDR agent on a small group of non-critical devices first. This allows your cybersecurity team to identify compatibility issues, performance impacts, and configuration problems in a safe environment.

Step 5: Install and Configure the EDR Agents Once testing is successful, proceed with installing the EDR agent on all identified endpoints. Follow the vendor's guidelines carefully. Use deployment tools to automate the installation across the organization to ensure consistency and save time.

Step 6: Configure Policies and Monitor Alerts After installation, configure your detection and response policies. Start with the vendor's recommended settings and fine-tune them based on your organization's risk profile. Begin monitoring the EDR dashboard for alerts and perform penetration tests to validate that the system is detecting and responding to threats as expected.

Step 7: Establish a Process for Continuous Updating Cyber threats evolve daily. Ensure your EDR solution is configured to update its threat intelligence and software automatically. A system that isn't regularly updated quickly becomes ineffective against new malware and ransomware tactics.

Protecting your business organization against the ground-breaking approaches and tactics developed by the best hackers in the world is not an easy task. Nowadays, these cybercriminals use the latest technologies and innovations to create ransomware attacks able to seize and export your sensitive information.

Over the last few years, ransomware attacks have changed significantly, and we can definitely say that they have metamorphosed with the adoption of artificial intelligence and have become a lot more dangerous and hard to recognize for traditional security measures, becoming a nightmare for every user and business owner.

The solution to all these advanced threats is named EDR. In the last few years, vendors of EDR services have also scaled up their security level by implementing AI and ML into their strategies for combating ransomware attacks. Today’s AI and ML-based endpoint security offers cutting-edge capabilities to fight ransomware, shape threat detection and response, and better defend client endpoints.

AI-based endpoint detection and response provides automated threat correlation and guided attack interpretations to save technicians time in investigation and readily move on to incident response activities. Continuous real-time monitoring uses behavioral-based detection, which lends an instrumental advantage against modern ransomware, especially in conjunction with signature-based detection.

Furthermore, the isolation and control of affected endpoints is a pivotal measure against ransomware incidents. The ability to contain and quarantine active threats prevents infections from spreading across healthy workloads and networks. Isolation can effectively disrupt the lateral movement of ransomware and minimize the impact of destruction on your endpoints.

To ensure robust protection against cyber threats, relying solely on EDR (endpoint detection and response) is not enough, especially when it comes to safeguarding your clients valuable data. It is essential to prioritize data protection as a component of cybersecurity measures. By integrating cybersecurity solutions with backup and recovery systems, you can enhance the resilience of your clients digital environments.

With new innovations, endpoint security has developed over time to address today’s challenges. Although traditional endpoint protection solutions prevent, protect, and eradicate ransomware with antivirus, firewall, and intrusion detection capabilities, these layers won’t be enough.

Effective EDR solutions provide a multi-layered defense against ransomware. Here are the essential features that make them so powerful:

• Behavior-Based Threat Detection: Instead of relying only on known malware signatures, EDR analyzes behavior to spot signs of an attack (IOAs), such as rapid file encryption or unusual process execution.
• Threat Intelligence Integration: EDR systems integrate with global threat intelligence networks to quickly identify known malicious files, IP addresses, and attacker tactics (TTPs).
• Real-Time Endpoint Monitoring: Provides complete visibility by continuously recording all activity on every endpoint, from process creation to network connections.
• Automated Incident Response: When a credible threat is detected, EDR can automatically take action, such as killing the malicious process and isolating the infected endpoint from the network to stop the ransomware from spreading.
• Centralized Investigation and Forensics: All endpoint data is stored in a central location, allowing security analysts to investigate threats, understand the full scope of an attack, and determine the root cause.

EDR implements comprehensive visibility at all endpoints to detect different indicators of attack and analyzes billions of real-time events to identify suspicious behavior towards the protected endpoint automatically.

Robust EDR security solutions strive to understand a single event as a part of a more significant sequence to apply security logic. If an event sequence points to a known IOA, the EDR solution will identify it as malicious and automatically issue a detection alert.

Integrated solutions combine threat and network monitoring with threat intelligence to swiftly identify any suspicious activity. In the event that the EDR tool detects any threatful tactics, techniques, and procedures (TTPs), it will provide information about potential security incidents prior to any data breaches taking place. This includes information on attackers, the vulnerable targets for attacks, how malware is being deployed, and other details about the attack.

EDR utilizes endpoint data aggregation to detect security incidents. Users are granted a view of all activities occurring on company endpoints from a cybersecurity standpoint. A dedicated solution is capable of monitoring security-related events such as process initiation changes to the registry loading of drivers, memory and disk utilization access, database network connections, and more.

Endpoint security solutions can investigate threats quickly and accelerate remediation with the blink of an eye. You can think of them as a security analyst, gathering data from each endpoint event and storing it in a massive, centralized database that provides comprehensive details and context to enable rapid investigations for both real-time and historical data.

All these key features confirm the EDR's reliability in the battle against ransomware and any other destructive threat. Having these features provided on your side is a real game-changer and will keep you protected 24/7.

According to the Acronis Cyberthreats Report for August 2023, ransomware detections at the endpoint level decreased by 6% from June to July. However, at the same time, Acronis Advanced Security + EDR detected over 150,000 cyber incidents, and notably, new ransomware gangs emerged, suggesting that ransomware attacks continue their development in their approaches and tactics, trying to penetrate security systems.

This leads to the conclusion that it is a matter of time for every business organization to face such an attack, because we cannot lie: there are millions of cybercriminals creating new and advanced ransomware attack tactics in order to gain monetary benefits.

On the other hand, the fact that EDR is one of the most powerful weapons to battle and intercept these destructive attacks definitely makes the use of EDR services a must. Because the question is not whether you will face a ransomware attack, it is when this event will happen.

So the best thing you can do for yourself and your business is to implement EDR solutions into your security posture in order to be as prepared as possible when this event occurs. Thus, you will provide yourself with peace of mind, knowing that you can rely on the fact that your sensitive information won't be stolen or encrypted.

The main question you must ask yourself is: How much do you value your sensitive information? Because, as we mentioned already in the article, the percentage of ransomware attacks is constantly rising, and these threats are waiting for the right moment to strike. So what price are you willing to pay? A monthly subscription plan, or the price of becoming a victim of a cybercriminal who will steal and encrypt all your priceless data?

EDR solutions provide you with privileged access to the latest approaches and technologies for protecting your endpoint devices and keeping you way off the dangerous zone of cyber attacks. We already know how important EDR tools like constant monitoring, threat hunting, threat intelligence, and immediate response are in the difficult task of protecting your valuable information 24/7.

All these tools are priceless when facing an unexpected scenario like a cyberattack. In these situations, you understand the power of the choice that you have made. Ensuring yourself with EDR solutions is a blessing in these moments, when you realize that they are actually a lifesaving option. So the cost of using EDR services is really insignificant, because the peace of mind that you will be provided with is far beyond that price. Knowing that your information and endpoint devices are protected with the latest technologies and tools is really a priceless feeling. There is no place for hesitation about whether to pay the cost of a subscription plan or not, risking losing all your precious information.

1. Is EDR a replacement for antivirus (AV)? No, EDR is an evolution of antivirus. While traditional AV focuses on preventing known threats, EDR is designed to detect and respond to the advanced, unknown threats that get past AV. Most modern solutions combine both capabilities into a single agent.

2. How does EDR specifically stop ransomware? EDR stops ransomware by detecting its characteristic behaviors, such as mass file modification and encryption. When it sees this activity, it can automatically kill the offending process and isolate the device before the encryption spreads across the network.

3. Is EDR difficult to deploy? While enterprise-wide deployment requires planning, modern cloud-based EDR solutions have streamlined the process significantly. By following a phased approach like the one outlined in this guide, most organizations can deploy EDR smoothly.

Unarguably, we conclude that using EDR services is the unnamed hero in the battle against ransomware attacks. This type of service goes beyond the traditional security measures, by using AI and ML, EDR stands as the most powerful weapon against cyberattacks. The effectiveness of EDR in anti-ransomware is remarkable. As per recent research made by Global Advanced Technologies, EDR is able to predict and prevent eight out of ten cyberattacks.

Furthermore, the most remarkable aspect of EDR is the complex synergy between all the tools used by this security measure. It is unbelievable how different components are managed to work together, like real-time monitoring, threat hunting, threat intelligence, AI and ML, and, of course, immediate response, in order to provide the best protection for the users.

The fact that EDR usage has increased by more than 60% over the past three years confirms the dominance of this type of cyber protection used by users and corporate clients. So, we can definitely conclude that if you want the best protection from becoming a victim of cybercriminals, you must take the step and start using EDR.
