Endpoint Detection and Response (EDR) is a process used in cybersecurity to track and respond to activities on devices like laptops, desktops, or servers. Here, we will discuss how endpoint detection and response works and protects your devices.
Collecting data from devices:
The first step in EDR is to collect information from endpoints. An endpoint is any device that connects to a network. EDR tools gather details such as file activity, system changes, and software behaviour. This information is sent to a central system for further review. The collection runs quietly in the background while the device is being used.
Detecting unusual behavior:
Once the data is collected, EDR tools scan for patterns that do not match normal behaviour. For example, if a file changes suddenly or a program starts doing something strange, the system marks it for attention. The tool does this by comparing the actions on the device to known threats or by spotting new behaviours that seem unsafe.
Sending alerts:
If the system notices anything suspicious, it creates an alert. This alert is sent to a central dashboard where security staff or software systems can review it. The alert usually shows what happened, which files or programs were affected, and when the action took place. This step allows the security team to act quickly.
Responding to the threat:
After an alert is reviewed, a response can be started. This might mean stopping a program, blocking a file, or removing the threat completely. Some EDR systems do this automatically, while others ask for approval before taking action. The goal is to stop the activity before it spreads or causes more damage.
Keeping records for review:
EDR tools also store records of events. These records help trace back what happened and how it started. This information can be useful later for improving security or checking if any data was taken. The saved data gives a full picture of the problem, from start to finish.
EDR systems work in a constant cycle collecting, watching, alerting, responding, and storing. By using these steps, they help maintain the safety of connected devices and reduce the chance of further problems. Each part of the process plays a part in keeping the system protected and aware of risks.
