Protect Your Endpoints Not Only Against Malware but Against Advanced Cyber Attacks

User computers, servers, laptops and remotely working systems are among organizations' most heavily used and most heavily attacked assets.

While traditional antivirus technologies continue to provide an important security layer in detecting known malware, attacks today no longer consist of classic malware files alone.

Modern attackers can use a wide range of different techniques such as;

PowerShell,
LOLBins,
credential dumping,
ransomware,
fileless malware,
lateral movement,
privilege escalation,
process injection,
command & control,
script-based attacks,
credential theft

and similar methods.

Modern endpoint security has therefore turned into an integrated security approach in which the;

AV + NGAV + EDR + Threat Intelligence + Behavioral Analysis + Threat Hunting + Automated Response

components work together.

SecureSys EDR & AV Solutions aim to make the security activity taking place on organizations' endpoints visible, to detect advanced attacks and to respond to threats quickly.

What Is AV – Antivirus?

Antivirus software is the core security technology for detecting and blocking the malicious files present on an endpoint.

Traditional antivirus systems work largely by using the signatures of known malware.

When a file matches a known malware sample, the system can carry out the;

Detect → Block → Quarantine

operations.

As attacker techniques have developed, however, signature-based protection alone has ceased to be enough.

What Is NGAV – Next Generation Antivirus?

Next generation antivirus solutions support traditional signature-based antivirus technologies with advanced technologies such as;

Machine Learning
Behavioral Analysis
Exploit Prevention
Script Analysis
Memory Protection
Reputation Analysis
Cloud Threat Intelligence

and similar capabilities.

The aim is thereby to detect threats at an early stage by analyzing the behavior of attacks not seen before or not yet holding a signature.

What Is EDR?

EDR – Endpoint Detection & Response is the security technology continuously monitoring the activity taking place on an endpoint, detecting attack behavior and giving security teams the means to respond to incidents.

EDR systems do not check only whether a malicious file is present.

By tracking;

which process is running,
which process started another process,
which files were created,
which changes were made to the registry,
which network connections were established,
which user account carried out the operation,
which commands were run

on the endpoint, they seek to analyze the entire behavior chain of an attack.

What Is the Difference Between AV and EDR?

Put simply;

AV: "Is this file malicious?"

focuses on this question.

EDR: "What is happening on this endpoint, and is this behavior part of an attack?"

tries to answer this question.

For example, rather than running malware directly, an attacker may run malicious commands through PowerShell.

Traditional antivirus may struggle to detect the attack because no known malware file is present.

EDR, by contrast;

Word ↓ PowerShell ↓ Encoded Command ↓ Network Connection ↓ Credential Access

can determine that the event is suspicious by analyzing a behavior chain of this kind.

How Does EDR Work?

In a modern EDR architecture the agent running on the endpoint continuously produces telemetry.

This information is sent to the central EDR platform.

The process generally runs as;

Endpoint Telemetry ↓ Behavior Analysis ↓ Threat Intelligence ↓ Detection ↓ Investigation ↓ Response

this sequence.

Endpoint Telemetry

EDR platforms can monitor a large number of the events taking place on an endpoint.

For example;

Process Creation
Process Termination
File Creation
File Modification
Registry Changes
Network Connections
DNS Requests
User Authentication
PowerShell Execution
Script Activity
DLL Loading
USB Activity

information of this kind can be used in security analysis.

This telemetry allows an attack to be followed from its starting point to its final stage.

Behavioral Detection

Modern attacks frequently try to avoid known malware signatures.

EDR platforms therefore use behavior-based detection techniques.

For example;

a normal Microsoft Word process starting PowerShell and then establishing a connection to an unknown address over the internet can be assessed as a suspicious behavior chain.

Rather than seeing these events as independent of one another, EDR relates them and analyzes the likelihood of an attack.

Fileless Malware

Fileless attacks can be carried out without leaving a classic malicious file on the endpoint.

The attacker can make use of the operating system's legitimate components such as;

PowerShell
WMI
Windows Script Host
rundll32
regsvr32
mshta

and similar tools.

These methods are among the important parts of Living off the Land attack techniques.

EDR technologies help detect attacks of this kind by analyzing process behavior and command chains.

Ransomware Protection

Ransomware attacks are among the most critical cyber threats, capable of halting an organization's operations entirely.

During a ransomware attack, behavior such as;

bulk modification of files,
deletion of shadow copies,
shutting down security services,
access to backup systems,
encryption of a high number of files in a short time

may be observed.

EDR platforms analyze this activity behaviorally with the aim of detecting ransomware attacks at an early stage and isolating the endpoint concerned.

Credential Theft Detection

Attackers may try to seize user and administrator credentials so they can move through the corporate network.

Endpoint security solutions can monitor behavior such as;

LSASS access,
credential dumping,
token manipulation,
browser credential theft,
suspicious privilege escalation

and similar activity.

These detections are of critical importance particularly in Active Directory based corporate estates.

Lateral Movement

After compromising a single computer, an attacker may try to move to other systems inside the organization.

This process is called Lateral Movement.

Attackers can use methods such as;

RDP
SMB
PsExec
WMI
PowerShell Remote
Remote Services

and similar techniques.

EDR telemetry can help detect lateral movement activity.

MITRE ATT&CK and EDR

Modern EDR platforms frequently relate security events to MITRE ATT&CK techniques.

For example, an attack's;

Initial Access → Execution → Persistence → Privilege Escalation → Credential Access → Discovery → Lateral Movement → Exfiltration

stages can be analyzed more clearly by security teams.

MITRE ATT&CK mapping helps SOC teams understand quickly which techniques the attacker used.

Threat Hunting

EDR is not merely a security system producing automatic alarms.

Security analysts can carry out proactive threat searches over endpoint telemetry.

During Threat Hunting;

suspicious processes,
IOCs,
hash values,
IP addresses,
domains,
persistence techniques,
privilege escalation attempts

can be investigated.

This approach helps bring out potential threats that have not yet produced an alarm.

IOC – Indicator of Compromise

IOCs are the technical indicators relating to an attack.

For example;

Malware Hash
Malicious Domain
Command & Control IP
File name
Registry key
URL

can be an IOC.

EDR platforms can compare the IOC data coming from threat intelligence sources with endpoint telemetry.

IOA – Indicator of Attack

While IOC focuses on the indicators emerging as a result of an attack, IOA analyzes attacker behavior.

For example, the;

Office application → PowerShell → Encoded Command → Internet

chain can be an attack indicator even when no particular malware hash is known.

In behavior-based EDR systems the IOA approach therefore carries great importance.

Endpoint Isolation

When an active attack is detected on an endpoint, one of the most important response methods is isolating the device from the network.

Applying;

Endpoint → Network Isolation

through EDR can prevent the attacker moving to other systems or communicating with the Command & Control server.

The security team's management connection is preserved so incident response can continue.

Kill Process

A malicious or suspicious process can be terminated remotely from the EDR console.

For example, when an active ransomware process is detected, the;

Detect → Kill Process → Isolate Endpoint

actions can be carried out.

File Quarantine

Malicious files detected can be quarantined on the endpoint.

The file is thereby prevented from running again and the spread of the incident is reduced.

Remote Investigation

Modern EDR platforms can allow security analysts to carry out remote investigation on the endpoint.

Analysts can determine the scope of an incident by examining;

running processes,
files,
network connections,
user activity,
system information

on the device.

Attack Storyline

A single attack can create dozens or hundreds of independent security events.

Rather than showing these events as individual alarms, a well-designed EDR system tries to relate them within the same attack chain.

For example;

Phishing ↓ Macro Execution ↓ PowerShell ↓ Credential Theft ↓ C2 Connection ↓ Lateral Movement

can be assessed as a single attack story.

This approach helps reduce the alarm fatigue of SOC teams.

EDR and SIEM Integration

EDR systems produce high-value telemetry relating to endpoint security.

When this information is carried into the SIEM platform, endpoint events can be correlated with other security sources such as;

Firewall
Active Directory
VPN
E-Mail
Proxy
DNS
Cloud

and similar systems.

For example;

Unusual login over VPN + credential dumping on the endpoint + privilege escalation on AD

assessing these events together can produce attack detections of higher accuracy.

EDR and SOAR

EDR security events can be connected to SOAR platforms so response processes are automated.

For example;

EDR Critical Alert ↓ SOAR Playbook ↓ Endpoint Isolate ↓ User Disable ↓ Firewall IP Block ↓ SOC Ticket ↓ Incident Response

automated response scenarios of this kind can be built.

The Difference Between EDR and XDR

EDR focuses largely on endpoint telemetry.

XDR, by contrast, analyzes different security layers alongside the endpoint together.

EDR — Endpoint
XDR — Endpoint + Network + Identity + Cloud + E-Mail

XDR can therefore be assessed less as a technology replacing EDR than as a security approach extending endpoint data with other security signals.

The Difference Between EDR and MDR

EDR is a technology.

MDR is the service through which those technologies are monitored and managed by expert security teams.

An organization may buy a strong EDR product, for example; but if there is no SOC team to analyze the critical ransomware alarm arriving at 03:00, a significant gap can open up in the security operation.

MDR service brings the;

EDR Technology + 24/7 SOC + Threat Hunting + Incident Response

approach together.

EDR and Active Directory Security

A significant part of endpoint attacks continues into the identity infrastructure.

After seizing user credentials on the endpoint, an attacker may try to escalate privilege within Active Directory and carry out lateral movement.

It is therefore important that EDR security is assessed together with the;

Endpoint Security + Identity Security + Active Directory Security

approach.

Server Security

EDR is not deployed only on user computers.

Windows and Linux servers are critical attack targets.

Endpoint telemetry can provide critical attack visibility particularly on;

Domain Controller
File Server
Application Server
Database Server
Web Server

these systems.

In server security, performance, application compatibility and the correct configuration of exclusion policies carry great importance.

Linux Endpoint Security

With the spread of Linux servers in corporate infrastructure, Linux EDR support has also become important.

On Linux systems, monitoring activity such as;

process execution,
privilege escalation,
shell activity,
suspicious binary,
network connection

is important particularly for protecting web, application and database servers.

macOS Security

The rise of macOS systems in corporate use shows that the scope of endpoint security must not stay limited to Windows alone.

The Windows, Linux and macOS coverage of the EDR solution an organization chooses should be assessed against its real device inventory.

USB and Device Control

USB and external device controls are an important component of endpoint security from a data loss prevention perspective.

According to policy;

USB can be blocked entirely,
only authorized USB devices can be permitted,
read-only access can be granted,
exceptions can be defined per user or group.

These capabilities can be applied together with DLP policy.

Web and Exploit Protection

Endpoint security solutions do not merely carry out malware detection.

Exploit protection mechanisms can help block different attack techniques such as;

memory attacks,
browser exploits,
Office exploits,
script-based attacks

and similar methods.

EDR and the Ransomware Response Scenario

A modern ransomware attack can develop as follows:

Phishing E-Mail ↓ Malicious File ↓ PowerShell ↓ Credential Theft ↓ Lateral Movement ↓ Domain Admin ↓ Ransomware Deployment

EDR's job is not merely to detect the ransomware file at the final stage.

It is to see the attack chain at the earliest possible stage and give the security team the opportunity to respond.

What Should You Consider When Choosing an EDR Product?

Looking only at a product's malware detection rate is not enough when choosing EDR.

The core criteria that need to be assessed:

Windows support
Linux support
macOS support
Server support
Behavioral Detection
Ransomware Protection
Threat Hunting
Endpoint Isolation
Remote Response
IOC Search
MITRE ATT&CK Mapping
Threat Intelligence
SIEM integration
SOAR integration
API support
Central management
Cloud / On-Premise options
Agent performance
False Positive rate
Ease of SOC use
Licensing model

should be these.

The EDR POC Process

Carrying out a controlled POC where possible before choosing EDR is the correct approach.

Within the POC;

Agent Deployment — the agent is deployed on the pilot endpoints and servers determined.
Policy Configuration — endpoint policies are built according to the organization's infrastructure.
Detection Tests — detection capabilities are assessed with controlled attack scenarios.
Response Tests — endpoint isolation, process termination and other response capabilities are tested.
SIEM Integration — the transfer of EDR events into the organization's SIEM/SOC infrastructure is assessed.
Performance Analysis — the agent's impact on endpoint resources is checked.

The SecureSys EDR & AV Approach

SecureSys does not treat EDR projects as endpoint agent deployment alone.

The organization's;

number of users,
number of endpoints,
number of servers,
operating systems,
Active Directory structure,
remote working model,
SOC infrastructure,
SIEM system,
existing antivirus infrastructure,
critical user and server groups

are analyzed first.

Then the;

Discovery → Product Selection → POC → Licensing → Pilot Deployment → Policy Design → Endpoint Deployment → Server Deployment → SIEM/SOC Integration → Threat Hunting → Operations → Reporting

processes can be applied.

EDR + SOC = Continuous Endpoint Security

EDR's greatest value comes not merely from detecting an attack but from the security signal produced being analyzed correctly.

In critical organizations, therefore;

EDR + SIEM + 24/7 SOC + Threat Hunting + Incident Response

should be assessed as an integrated whole.

Determining whether an EDR alarm is a real attack, a false positive or the start of a wider attack chain requires expert security analysis.

Protect Your Endpoint Not Only Against Viruses but Against Attackers

Traditional antivirus is only one layer of modern endpoint security.

Against fileless malware, ransomware, credential theft, lateral movement and advanced attack techniques, organizations need to monitor the behavior taking place on the endpoint continuously.
