Because EDR is important.
As more and more businesses go digital and more of their information is stored in the cloud, the rewards for cyberattacks become bigger. This leads to more attempts and the development of new ways to attack. The best way to protect your data and systems from these attacks is to have an advanced, intelligent, detection and response system. (endpoint security)
EDR can provide this protection and can detect and respond to threats that traditional systems can’t see or deal with. Traditional tools use “signature-based detection,” which means that they match attack artefacts to known threats or files. In place of this, EDR uses event and behaviour analysis, which allows it to find suspicious activity even if it’s a known threat or a new vulnerability.
Applying these abilities to your endpoints is very important to protecting your systems. Endpoints are the doors that lead to your networks. As long as you use EDR to keep your network perimeter safe, you can stop most or all of the attacks that might try to get into your systems. This becomes more important as networks grow.
Adding Internet of things (IoT) devices, smartphones, and workstations from outside the network makes network protection more difficult. EDR can keep an eye on and control these extra endpoints from a single place, preventing gaps in your defences.
What types of threats does EDR look for?
Another thing that EDR can help protect against is an attack that doesn’t work through traditional security systems. These attacks are:
Attacks that have more than one stage
EDR’s ability to keep collecting and analysing data allows it to connect events that might not seem suspicious when looked at alone. By comparing these events, EDR solutions can find out about multi-stage attacks, like reconnaissance, that start with a single attack. These attackers can then be blocked from getting in at all entrance points, sometimes even before they try to get in.
A virus that doesn’t need a file or a way to get into your computer is called “file
Because EDR is based on behaviour analysis instead of signatures, it can detect new and process-based attacks. For example, EDR can find processes that are run by fileless malware, which runs in the memory. This malware doesn’t write files to the hard drive, so antivirus software can’t find it.
Insider threats and hacked accounts, endpoint security
When credentials are used to carry out attacks, the only way to find out about the threat is to look at how people act. Insider threats and attacks that use stolen credentials can “legitimately” get through security and authentication measures.
EDR, on the other hand, can tell when credentials are used in ways that aren’t normal, like accessing networks from outside IP addresses. It can then block these people, stopping the attack.

Asked how EDR works:
Endpoint event data is collected by EDR solutions and stored in a single database. This data is then looked at and correlated to find suspicious events. Suspicious activity is found through a mix of matching to known threats and comparing behaviour to established baselines.
Threat signatures are characteristics that can be used to find out if there are problems or attacks. For example, known malware hashes or old software versions that aren’t up to date. This is how it works: Behavioral baselines are datasets made up of events that are thought to be safe. For example, normal times to log in or acceptable ways to access files.
Once an event is found to be suspicious, EDR alerts you to the event and can stop other events or stop running processes from taking place. To figure out if an event is really an attack, security analysts can respond to these alerts and look into the event. Log data from EDR helps analysts figure out what happened, and correlation data helps them figure out what to do next.
In this example, we’re going to compare Endpoint Solutions: EDR and EPP.
It is possible to use endpoint protection platforms (EPPs) or endpoint security to find and stop threats on your devices. These are all-in-one security solutions that work together. EPP platforms are designed to stop attacks, and they usually use signature-based methods to do this. Endpoint protection platforms use a variety of technologies, such as:
In order to protect your computer from viruses and malware, you need to have anti-virus and anti-
Protocols for encryption
People who want to keep out hackers on their network and apps use firewalls.
Security systems (IPS) and data loss prevention (DLP) solutions are called “IPS” and “DLP.”
Most people don’t think about the difference between EPP and EDR. EPP is meant to be the first line of defence against attacks. In contrast, EDR is meant to find and respond to attacks that get through the first line of defence. Because EPP solutions and EDR solutions are becoming more common, it’s hard to tell them apart.
When Choosing an EDR Solution, think about these things:
EDR is still a very new technology, but it has a lot of new options and abilities. When you choose an EDR solution, you have a lot of options to choose from, but not all of them are the same. To make sure that you are getting the best possible protection, look for the following:
Solutions should give you real-time access to all of your endpoints. This includes communications, applications, and processes that can be seen. Solutions should also make it easy to access logs for forensic analysis both during and after an event.
Threat database: Solutions should have a threat intelligence database in them. This database should be able to get information from other databases and be able to add information that is specific to your network.
Behavioral protection: Solutions should have engines that look at how people act. These engines must be able to show you how people move around your network and resources.
Fast solutions should work in real time, send out accurate alerts, and be able to handle threats on their own. This means that you need detection engines that don’t make a lot of false positives and the ability to set automated response policies.
In this case, solutions are cloud-based, and they can protect your network without slowing down the performance of end points. These solutions should be easy to use from afar and work well with current systems.
EDR: The Most Common Mistakes to Keep from Making
When you start using EDR solutions, it can be hard to change how you use them. To make sure you’re getting the most out of your solution’s protection, avoid these mistakes.
Preventing too much
When you decide to use an EDR system, you should not focus too much on how well it can stop things from happening. Despite the fact that there are EPP and EDR solutions that work together, most of them aren’t ready yet and can’t provide the same level of protection as dedicated solutions.
Instead, you should choose separate but complementary solutions. Focusing on finding solutions that work well together gives you reliable prevention and protection without sacrificing anything.
If you have to choose a mixed solution, make sure you know what it can do. You need to know what a solution can protect you from and how it compares to your other solutions when it comes to being able to stop things before they happen. For example, is the solution a replacement for your current antivirus or just an extra layer of protection?
Also, make sure you know how the solution you choose is going to change. If you don’t use preventative features in planned releases, they won’t help you.
We have a guide that talks about EPP solutions. You can learn more about them there: EPP Security: Prevention, Detection, and Response.
Not setting up a triage or response process
EDR tools can do a lot of the work for you so that you don’t have to do it yourself, but they aren’t magic. You still need to keep track of tools, respond to alerts, and deal with threats after solutions are in place.
You can trust security teams to do these things quickly, but this can lead to inconsistencies and oversight. Instead, you should write policies and procedures that outline how solutions are managed and how teams investigate and respond to problems and problems.
