Endpoint Detection and Response (EDR)

What is Endpoint Detection and Response (EDR)?

An EDR solution is designed to detect and respond to advanced attacks targeting your company’s endpoint devices. 

EDR products can automatically detect malicious applications on endpoints, stop processes communicating with remote hosts, quarantine compromised endpoints, and remove any malicious code from them before it can infect other devices. The best EDR solutions can provide more effective protection against zero-day attacks.

How does Endpoint Detection and Response (EDR) work?

EDR solutions work by monitoring the behavior of processes and applications on endpoints and then launching the correct response based on the behavior of the application. This behavior-based monitoring relies on three key components:

Behavior detection technology

Behavior detection technology is useful to watch how applications and processes behave as they perform their normal tasks, looking for suspicious activity. For example, if an application is supposed to create a new file in a specific location on disk. But instead creates a file in an unexpected location, EDR will detect this as anomalous behavior.

Detection engine

The detection engine is useful to evaluate the detected behavior of an application against threat intelligence feeds and security policies to determine the appropriate response. If a suspicious file is in an unexpected location, the detection engine will identify this as suspicious activity and may choose to quarantine or remove it from the system.

Response engine

The response engine executes a response against a threat or attack detected by EDR. For instance, basing on a policy configured by security professionals in real-time or pre-defined as part of a security policy. 

The response could be anything from quarantining or removing malicious code from an endpoint, to blocking communications with malicious hosts.

Why do you need Endpoint Detection and Response (EDR)?

Traditional signature-based anti-malware software can struggle to protect you against Zero-day attacks, advanced malware evasion techniques, or targeted malware designed to attack your business systems specifically. 

EDR solutions help overcome these challenges with advanced malware detection technology designed to identify new types of malicious files and known threats that have already evaded other detection techniques, allowing you to more effectively protect your company’s endpoints from cyber attacks.

Phishing attacks – how can you protect yourself?

Phishing attacks are typically out over email and are into trick users into clicking on links or attachments sent via email that either direct them to a fake login page for the company’s website, hoping to capture login credentials or deliver malware to the user’s computer. 

In addition, phishing emails are often having well designs and look like legitimate messages from a company you work with or a bank with, leading users to believe that the email is legitimate.

To protect yourself from a phishing attack, there are a few things you can do: 

1. Never click on links inside an email or open attachments unless you are sure they are safe. 

2. Don’t reply to the email. Instead, contact the company directly via telephone or email to check that they sent the message. 

3. If you have ever provided your account details/login

4. When you have confirmed that the message is legitimate, never click on the link in the email to log in to your account. Instead, type in the address manually into your browser. This way, you will know for sure that you are logging into the correct site. 

5. If you are unsure whether a message is a phishing attack or not, don’t click on it. 

6. If you are unsure if a file is safe or not, do not open it.
