EDR
Endpoint detection and response (EDR) platforms are solutions that monitor endpoints (computers on the network, not the network itself) for suspicious activity. EDR solutions focus on end-user devices – laptops, desktops, and mobile devices.
EDR solutions provide visibility and monitoring for suspicious activity like malware and cyberattacks on those end-user devices.
EDR Tools:
EDR tools are technology platforms that can alert security teams of malicious activity, and enable fast investigation and containment of attacks on endpoints. An endpoint can be an employee workstation or laptop, a server, a cloud system, a mobile or IoT device. EDR Tools : Clicke Here
EDR solutions typically aggregate data on endpoints including process execution, endpoint communication, and user logins; analyze data to discover anomalies and malicious activity; and record data about malicious activity, enabling security teams to investigate and respond to incidents. In addition, they enable automated and manual actions to contain threats on the endpoint, such as isolating it from the network or wiping and reimaging the device.
Why is EDR Important?
Every device that connects to a network is a potential attack vector for cyberthreats, and each of those connections is a potential entry point to your data. With the rise of BYOD (bring your own devices), mobile attacks and sophisticated hacking techniques have only increased your risk of data breaches.
EDR solutions help protect those points of entry into your network by monitoring your endpoints for many modern threats that anti-virus software is unable to detect.
EDR solutions can help monitor and protect against Advanced Persistent Threats (APT), which often use malware-free hacking techniques and security vulnerabilities to gain access to a network. Older anti-virus software is able to detect malware only when there is a matching signature, and is unable to determine that an attacker has access to a computer just by monitoring their activity.
Endpoint security is not just an enterprise tool: there are consumer versions of EDR out there these days as well. A few differences in how endpoint security differs for consumers and enterprises include:
Remote management and central storage:
Enterprises typically provide remote management options so security administrators can configure the appropriate settings. Each endpoint sends audit data to a central repository for audit and analysis.
Consumers don’t need the same centralized administration.
Auto-updates vs. distributed patches:
Enterprises need to adhere to change management processes, which requires the enterprise to distribute patches during those windows.
Consumers usually allow the EDR to auto-update per the vendor’s release schedule.
EDR solutions typically provide the following capabilities:
Data Collection and Analytics—
Collects a wide range of security-related event data from each endpoint, including data such as:
Process creation
Drivers loading
Registry changes
Disk accesses
Network connections
Performs behavioral analysis on the data to uncover both potential threats as well as malicious activity that is already in progress. The analysis may make use of threat intelligence built into the EDR solution to provide context for the endpoint data that helps identify a threat. The analysis looks for Indicators of Compromise (IoC) and Indicators of Attack (IoA). The objective is to find threats that slip past signature-based AV methods of detection.
Detection – Detects advanced threats, such as fileless attacks, zero-day exploits and others, in real time.
Visibility – Gives you real-time visibility across all your endpoints, enabling you to see the attack path and take immediate action.
Automated Response – EDR tools can take a number of different steps to remediate or contain an attack, including:
Deleting files and blocking the spread of suspicious files
Terminating processes
Isolating the endpoint on the network to prevent lateral movement of the attack
Automatic or manual execution of suspicious payloads in a sandbox
Remote script execution on the endpoint
Reporting and Alerts – Use real-time dashboards and get alerts to take action when a threat is detected.
9 Elements of EDR Solutions
Endpoint detection and response solutions can have a range of features – but there are a set of core elements that are essential to EDR:
Console Alerting and Reporting: A role-based console that provides visibility into the organization’s endpoint security status
EDR Advanced Response: Advanced analysis and response capabilities of EDR solutions, including automation and detailed forensics about security incidents
EDR Core Functionality: The capability to detect and report on security threats and vulnerabilities on the endpoint
EPP Suite: Basic functionality that was available in the previous generation of endpoint security software including anti-malware, anti-phishing, and anti-exploit capabilities
Geographic Support: An EDR vendor’s capability to support a global enterprise – because information security is mission critical
Managed Services: The EDR’s ability to feed data to a Managed Security Service or Managed Detection and Response vendor to further augment the security team’s capabilities
OS Support: In order to be effective, an EDR needs to support all of the operating systems in use by your organization,
Prevention: It’s not enough to simply detect a threat – effective EDRs need to provide preventative measures as well, to help mitigate and enable teams to take action.
Third-Party Integration: A comprehensive data security strategy often requires integrating with multiple products: EDRs should have APIs or built-in integrations with other solutions to complement and deliver on a layered security approach.
Endpoint Security vs. Anti-Virus Software
As noted in the list above, anti-malware is still a key component of EDR solutions. Older generations of anti-virus software detect threats by a signature, needed in advance in order to be able to detect the malware. The next generation of EDR solutions includes predictive analysis and advanced threat detection to better protect users.
Additional features found in EDR solutions that are not included in traditional AV solutions include:
Malware removal based on matching signatures and analytics
Antispyware protection
Local firewall
Intrusion detection and intrusion prevention warning systems
Application control and user management
Data control, including portable devices
Full Disk Encryption
Data Leak Prevention
Application Whitelisting
