16 Types of Endpoint Security Risks To Watch Out For

You’ve likely heard horror stories of major companies falling victim to devastating cyber attacks. As of 2023, the average cost of a data breach rose to $9.48 million. The common thread? Many attacks start by exploiting vulnerabilities in endpoints – laptops, smartphones, servers, and other networked devices connected to your systems or corporate networks.

As businesses embrace remote work and cloud computing, with remote employees using remote devices, securing those endpoints has never been more critical. In this guide, we’ll explore the top endpoint security risks facing organizations today and discuss effective strategies to protect your digital assets.

What are Endpoint Security Risks?

Endpoint security risks refer to the potential security threats that malicious actors can exploit to gain unauthorized access to an organization’s network, data, or systems. Examples of endpoint devices include laptops, mobile phones, and Internet of Things (IoT) devices.

With more employees working remotely and using individual devices to access corporate resources, the attack surface for cybercriminals has expanded significantly. Employee devices that are unsecured, vulnerable endpoints serve as entry points, enabling threat actors to move laterally across the network and compromise critical systems.

16 Types of Endpoint Security Risks

Protecting your organization starts with understanding the diverse range of threats targeting endpoints. Here are some of the most common endpoint security risks:

  1. Phishing
  2. Data Leaks
  3. Malicious Insider Threats
  4. Stolen or Lost Devices
  5. Malware
  6. Mobile Device Management
  7. Business Email Compromise (BEC)
  8. Vendor Access / Vendor Endpoints
  9. DDoS Attacks
  10. Macro and Script Attacks
  11. Advanced Persistent Threats
  12. Unsecured Data Transfer
  13. Insufficient BYOD Policies
  14. Lack of Employee Security Training
  15. Delayed Alerts
  16. Shadow IT

1. Phishing

Phishing attacks employ social engineering techniques to manipulate users into revealing sensitive information or granting access to systems. Common phishing methods include spoofed emails appearing to be from legitimate sources, such as banks, delivery companies, or coworkers. 

These phishing emails often contain malicious links that, when clicked, install malware or direct victims to fake login pages designed to steal credentials. Phishing campaigns may leverage SMS texts, social media, and even phone calls to lure victims.

2. Data Leaks

Data leaks expose confidential or proprietary information to unauthorized parties, whether accidentally or intentionally. 

Accidental data leaks can occur when employees mishandle files by emailing them to the wrong recipient, uploading them to insecure cloud storage, or losing unencrypted network devices. Malicious insiders may deliberately exfiltrate sensitive data for personal gain or to benefit competitors. Even improper data disposal practices that fail to wipe devices thoroughly can enable data leakage.

3. Malicious Insider Threats

Insider threats originate from individuals within an organization who abuse their legitimate access privileges for illicit purposes. This may involve stealing corporate data, intellectual property, or financial information for profit, espionage, or sabotage. 

Disgruntled employees or those recruited by external threat actors can intentionally cause service disruptions, delete or corrupt data, or create backdoor access for further compromise. Even negligent or careless insiders who mishandle data pose significant risks.

4. Stolen or Lost Devices

If proper safeguards are not in place, the loss or theft of endpoint devices like laptops, smartphones, and tablets can seriously compromise an organization’s data security. 

Sensitive emails, documents, credentials or other data stored on unencrypted or improperly secured devices could potentially be accessed by unauthorized users. Without remote desktop control capabilities, device locks, or other protective measures, lost or stolen endpoints increase the risk of exposing confidential information.

5. Malware

Malware threats such as viruses, worms, trojans, ransomware, spyware, and other malicious code represent a persistent threat for endpoint attacks. Users who fall victim to social engineering lures or web-based drive-by downloads may inadvertently download malware.

Once present on an endpoint or connected device, sophisticated threats and malware can move laterally across company networks, exfiltrate data, encrypt files for ransom, or enlist infected devices into botnets for further attacks on endpoints. Rootkits and fileless malware strains are especially difficult to detect and remove.

6. Mobile Device Management

The widespread use of mobile devices, including smartphones and tablets, in the workplace has expanded the attack surface for cybercriminals to target mobile endpoints. 

Without robust mobile device management (MDM) policies and security controls, these devices risk exposing corporate data through insecure Wi-Fi connections, lax app permission settings, or insecure messaging platforms. Lost or stolen mobile devices can readily expose unprotected data, and inadequate mobile patching and update practices compound these risks.

7. Business Email Compromise

In business email compromise (BEC) attacks, cybercriminals spoof or gain access to an executive or employee’s email account to impersonate that individual. 

They may then send fraudulent wire transfer requests, fake invoices, data solicitations or other illegitimate business directives to coerce victims into transferring funds or sensitive data. To enhance their deceptive tactics, BEC attacks often involve careful research into corporate hierarchies, vendor relationships, and communication styles.

8. Vendor Access / Vendor Endpoints

Third-party vendors and contractors frequently require some degree of access to an organization’s systems, data, or cloud networks to support products or services. If not properly managed and secured, each of these external connections represents a potential vector for cyber threats. 

Threat actors may attempt to compromise vendor credentials or exploit vulnerabilities in vendor-supplied software to gain initial access, enabling lateral movement and further compromise.

9. DDoS Attacks

Distributed denial of service (DDoS) attacks attempt to overwhelm servers, wireless networks, websites, and other resources by flooding them with malicious traffic from a coordinated array of compromised systems acting as a “botnet.” 

Successful DDoS attacks can render systems inaccessible to legitimate users and customers by consuming available bandwidth or exhausting other computing resources. Infected endpoint devices, such as computers and IoT devices, are often recruited into these botnets.

10. Macro and Script Attacks

Malicious macros embedded in office application documents like Word files or spreadsheets can contain malicious code set to execute when the file is opened automatically. 

Similarly, scripts inserted into applications or operating systems can be leveraged to deliver malware payloads. These attacks take advantage of end-user trust in common file types and productivity tools to sneak malware past defenses. Cybercriminals continually devise new obfuscation techniques to bypass security detection of malicious scripts and macros.

11. Advanced Persistent Threats

Advanced persistent threats (APTs) are sophisticated, multi-stage cyberattacks orchestrated by highly capable threat actors like nation-states or organized criminal groups. APTs methodically establish persistent, hard-to-detect footholds within target networks through stealthy techniques like zero-day attacks or social engineering attacks. 

The goal of these malicious attacks is to maintain covert access to monitor activity and steal sensitive data over extended periods continually. Defending against these advanced threats requires advanced endpoint security solutions, such as behavior analysis and comprehensive network monitoring.

12. Unsecured Data Transfer with USB Devices

The widespread use of USB storage devices for transferring data between systems and air-gapped private or public networks presents multiple security concerns. When infected devices are connected, USB drives can inadvertently spread malware. 

Data exfiltration risks arise if drives containing sensitive information are lost or stolen. Even USB charging connections for devices could potentially enable data leaks or malware injection if not properly secured.

13. Insufficient BYOD Policies

The bring your own device (BYOD) trend, accelerated by remote work scenarios, enables employees to access corporate data on their personal smartphones, tablets, and laptops. 

Without robust BYOD security policies and technical controls to enforce them, these devices lack uniform protection and monitoring. This raises risks like data loss, unauthorized app installations, weak passwords, and improper configuration settings that cybercriminals can exploit.

14. Lack of Employee Security Training

Even with robust technical security measures in place, employees who lack sufficient cybersecurity awareness training remain a significant risk factor. Untrained staff may fall victim to social engineering ploys like phishing, inadvertently exposing data through improper practices, or disregarding security protocols through carelessness or workarounds. 

15. Delayed Alerts

Every second counts when responding to an active cyber threat or security incident involving endpoint devices. 

Delayed detection and alerting enable threats like malware infections, unauthorized access attempts, and data exfiltration activities to persist unmitigated. This expands the potential for damage while narrowing the window for effective incident response and recovery. Endpoint security solutions capable of continuous real-time monitoring and automated threat detection are vital.

16. Shadow IT

The use of unauthorized applications, cloud services, or devices in the workplace constitutes “shadow IT.” 

When endpoint users install unapproved software or leverage unsanctioned cloud storage or computing services, they create vulnerabilities and lack visibility for security teams. Undocumented shadow IT components lack the proper vetting, monitoring, patching, and access controls, negating existing endpoint management solutions. They also increase the overall attack surface cybercriminals can target.

By understanding endpoint devices’ diverse risks, organizations can implement more robust, comprehensive security strategies tailored to mitigating their specific threat landscape. A defense-in-depth approach remains crucial in today’s continually evolving cybersecurity environment.

How To Prevent Endpoint Security Risks

While the threats are daunting, a proactive approach to developing robust endpoint security strategies will significantly reduce your exposure. Here are some proven strategies:

Use Endpoint Monitoring Software

Implementing endpoint monitoring software and tools is essential. These tools secure endpoints using techniques like application whitelisting, anti-malware scanning, data encryption, and system hardening.

Leading solutions provide real-time visibility into all endpoints, enabling rapid detection and response to potential threats. For example, if an employee’s laptop is infected with ransomware, the software can automatically isolate the device from the network and push security updates to remediate the issue before it spreads.

Leverage Data Loss Prevention Tools

Data Loss Prevention (DLP) solutions monitor and control the flow of sensitive data across endpoints and networks. They can automatically redact or block the transmission of confidential information, protecting against accidental data leaks and malicious exfiltration attempts.

With detailed reporting and policy enforcement capabilities, DLP tools empower organizations to take a proactive stance against data breaches.

Setup User & Entity Behavior Analytics (UEBA)

User and Entity Behavior Analytics (UEBA) leverages machine learning and data analysis to establish baselines of normal user and system behavior across endpoints. UEBA can swiftly detect anomalous activities indicative of threats like insider abuse or compromised devices by continually monitoring for deviations.

Early warning of these indicators enables prompt investigation and incident response before major damage occurs.

Implement an Insider Threat Program

An insider threat program combines policies, training, monitoring tool, and response protocols to mitigate risks from malicious or negligent insiders. This holistic approach deters, detects, and mitigates insider threats that could lead to data exfiltration or sabotage.

Key elements include regular security awareness education, user activity monitoring, data access controls, and mechanisms for safe reporting of concerns.

Define an Endpoint Security Policy

A comprehensive endpoint security policy provides clear guidelines on authorized device usage, antivirus software installations, data handling, and reporting procedures. It specifies technical requirements like encryption, password standards, and software patch management.

Properly documented and enforced, this policy establishes guardrails that significantly reduce human error and potential vulnerabilities across your endpoint landscape.
