Endpoint Security

Endpoint security is the process of protecting devices like workstations, servers, and other devices that can accept a security client from malicious threats and cyberattacks. Endpoint security software enables businesses to protect devices that employees use for work purposes or servers that are either on a network or in the cloud from cyber threats.

The modern business landscape is seeing an increasing volume of cybersecurity threats from increasingly sophisticated cyber criminals. Hackers launch a cyber attack every 39 seconds with a daily total of 2,244 attacks. Endpoints are one of the most common targets, given the sheer number of them in use to connect to networks. According to strategy Analytics insight there were already 22 billion connected devices in 2018, which is predicted to rise to 38.6 billion devices by 2025 and 50 billion devices by 2030. As a result verizon’s threat report found that up to 30% of data breaches involved malware being installed on endpoints.

Every endpoint that connects to the corporate network is a vulnerability, providing a potential entry point for cyber criminals. Therefore, every device an employee uses to connect to any business system or resource carries the risk of becoming the chosen route for hacking into an organization. These devices can be exploited by malware that could leak or steal sensitive data from the business..

The Benefits of An Endpoint Security

Endpoint security technology plays a vital role in protecting organizations from the increasingly dangerous threat landscape. Some of the key benefits of an endpoint security approach include:

1. Protecting all endpoints: As employees now connect via not only a growing number of endpoints but also different types of devices, it is vital for organizations to ensure they do so securely. They also need to ensure that the data on those devices is secure and cannot be lost or stolen. 
2. Securing remote working: The rise in device usage is linked to new ways of getting work done and remote working policies. These policies enable employees to be as effective as possible wherever they are and on any device. However, they also make it more difficult to ensure users are working securely, thus creating vulnerabilities for hackers to exploit. Protecting the device with an endpoint security platform is crucial.
3. Sophisticated threat protection: Hackers are deploying more sophisticated attack methods that see them come up with new ways of gaining access to corporate networks, stealing data, and manipulating employees into giving up sensitive information. Endpoint protection is critical to securing the modern enterprise and preventing cyber criminals from gaining access to their networks.
4. Protecting identity: As employees connect to business systems via various devices and from different networks and locations, the traditional process of protecting the business perimeter is no longer viable. Endpoint security ensures that the business puts security on employees’ devices, enabling them to work safely regardless of how and where they connect to corporate data.

How Does Endpoint Security Work?

The main goal of any endpoint security solution is to protect data and workflows associated with all devices that connect to the corporate network. It does this by examining files as they enter the network and comparing them against an ever-increasing database of threat information, which is stored in the cloud. 

The endpoint security solution provides system admins with a centralized management console that is installed on a network or server and enables them to control the security of all devices connecting to them. Client software is then deployed to each endpoint, either remotely or directly. With the endpoint set up, the software pushes updates to it whenever necessary, authenticates login attempts that are made from it, and administers corporate policies. 

In addition, the endpoint security solution secures endpoints through application control. This blocks the user from downloading or accessing applications that are unsafe or unauthorized by the organization. It also uses encryption to prevent data loss.

The endpoint security solution enables businesses to quickly detect malware and other common security threats. It can also provide endpoint monitoring, detection and response, which enables the business to detect more advanced threats like file less malware, polymorphic attacks, and zero-day attacks. This more advanced approach provides enhanced visibility and a wider variety of response options in the face of a security threat.

Types of Endpoint Security

1. Security for the Internet of Things

IoT devices are becoming more common in enterprise infrastructures as they aid communication and business processes. Unfortunately, endpoint security is typically built into IoT devices.

IoT security is one of the sorts of endpoint security offered for businesses to address this problem. These solutions help increase IoT device visibility, provide a consistent and straightforward layer of protection, and close network security holes.

2. Endpoint Detection and Response

EDR is one of the most popular endpoint security technologies since it provides a feature that works with the detection-mitigation model of modern cybersecurity. EDR solutions monitor every file and program that enters your company’s endpoints. EDR solutions can provide granular visibility, threat investigations, and ransomware and file-less malware detection. Additionally, EDR alerts your investigation teams so that prospective threats can be quickly identified and eliminated.

3. Antivirus Solution

Antivirus solutions continue to offer essential features and are arguably one of the most well-known and widely used types of endpoint security. These have antimalware features. As a result, businesses can defend against signature-based assaults, which occasionally happen. Additionally, by consulting with threat intelligence databases, antivirus software scans files for dangerous threats.

4. Browser Isolation

Surprise downloads; zero-day attacks, ransomware, crypto-jacking malware, and dangerous browser-executable code are just a few of the web browser attacks. Browser isolation uses segregated contexts where it cannot access valuable digital assets to carry out surfing sessions. Activity is still limited to safe, interactive media streams and isolated locations. After the user is done browsing, the application also eliminates web browser codes.

5. URL Filtering

URL filtering restricts online traffic to reliable websites. Additionally, URL filtering can stop shady downloads on your network, giving you more control over who and where downloads what.

6. Application Management

It should come as no surprise that application control manages permissions for apps, establishing strict limitations on what they can or cannot do. To achieve this, it employs whitelisting, blacklisting, and graylisting to stop malicious programs from launching and compromised applications from operating in a risky manner. This becomes crucial as businesses continue to use the cloud and the possibilities of external applications in their operations.

7. Secure Email Gateways

The primary method of data traffic entering and leaving your digital network is email. Thus, hackers use emails more than any other attack vector to disguise and spread their exploits. They may utilize email as their primary method of spreading malware up to 90% of the time, if not more.

Secure email gateways monitor suspicious activity in incoming and outgoing communications and block it from delivery. They can be set up to avoid phishing attempts by your IT infrastructure.

8. Network Access Control

NAC employs firewalls, which are placed between users, devices, and sensitive areas of your network.

9. Data Loss Prevention

A data loss prevention (DLP) strategy ensures that your most secure data resources are protected against exfiltration. One of the best ways to safeguard these assets is to keep employees informed about phishing tactics and install antimalware to prevent data loss from malicious programs hackers install on your endpoints.

10. Insider Threat Protection

Insider threats originate within your organization. Endpoints can be protected by controlling who has access to certain areas of your network, monitoring what they are doing, and ensuring all sessions are appropriately ended. Utilizing zero-trust network access (ZTNA) solutions is critical to governing who can access sensitive locations within your organization.

11. Data Classification

Companies use data classification to determine the endpoints that can be utilized to get unauthorized access to the most valuable and sensitive data. For example, a company may have multiple customer service employees who operate remotely and access critical financial information about its customers. In this case, data classification may aid in identifying a vital attack surface.

12. Cloud Perimeter Security

Cloud perimeter security in endpoints entails safeguarding your cloud resources against unauthorized devices and users. For example, a cloud firewall can restrict who and what devices can access your cloud resources. You can also utilize web filtering technologies that are hosted in the cloud.

13. Sandboxing

Sandboxing allows you to build an environment that mimics your regular end-user operating system while separating it from vulnerable network locations. Because you can sandbox individual applications, this can work with most types of endpoints.

What Is an Endpoint? – Endpoint Definition

An endpoint can be considered as a device that enables an employee to connect to a corporate network. The growth in BYOD and other connected systems such as the Internet of Things is seeing the number of devices that could potentially connect to a network increase exponentially.

Some of the more common devices that can be considered an endpoint include:

• ATM machines
• IoT-enabled smart devices
• Industrial machines
• Laptop computers
• Medical devices
• Mobile phones
• Printers
• Servers
• Tablet

Wearables, such as smartwatches Endpoints now extend beyond the laptops and mobile phones that employees use to get their work done. They encompass any machine or connected device that could conceivably connect to a corporate network. And these endpoints are particularly lucrative entry points to business networks and systems for hackers. It is therefore vital for organizations to consider every device that is or could be connected to their network and ensure it is protected. Furthermore, as the endpoints evolve and increase in sophistication, so too do the security solutions that protect them from being exploited.

Why is Endpoint Security Important?

In today’s digital age, endpoints are often the first line of defense against cyberattacks. With the increasing number of remote workers and the growing complexity of IT environments, the risk of breaches has never been higher. Endpoint security helps protect your organization from:

• Malware: Viruses, ransomware, and other malicious software.
• Data breaches: Unauthorized access to sensitive information.
• Insider threats: Malicious actions by employees or contractors.
• Compliance violations: Failure to meet industry regulations.

Key Components of Endpoint Security

• Endpoint Protection Platform : A comprehensive suite of tools for protecting endpoints.
• Endpoint Detection and Response : Advanced threat hunting and incident response capabilities.
• Mobile Device Management : Securing and managing mobile devices.
• User and Entity Behavior Analytics : Detecting anomalies in user behavior.
• Patch Management: Keeping software up-to-date with the latest security patches.

Best Practices for Endpoint Security

• Implement a layered defense: Use multiple security controls to protect against various threats.
• Keep software up-to-date: Apply security patches promptly.
• Educate employees: Train staff on cybersecurity best practices.
• Regularly review and update security policies: Stay ahead of evolving threats.
• Use strong authentication: Require multi-factor authentication.
• Back up your data: Regularly back up important data to protect against ransomware.

Core functionality of an endpoint protection solution

Endpoint security tools that provide continuous breach prevention must integrate these fundamental elements:

1. Prevention: NGAV

Traditional antivirus solutions detect less than half of all attacks. They function by comparing malicious signatures, or bits of code, to a database that is updated by contributors whenever a new malware signature is identified. The problem is that malware that has not yet been identified — or unknown malware — is not in the database. There is a gap between the time a piece of malware is released into the world and the time it becomes identifiable by traditional antivirus solutions.

Next-generation antivirus (NGAV) closes this gap by using more advanced endpoint protection technologies, such as AI and machine learning, to identify new malware by examining more elements, such as file hashes, URLs, and IP addresses

2. Detection: EDR

Prevention is not enough. No defenses are perfect, and some attacks will always make it through and successfully penetrate the network. Conventional security can’t see when this happens, leaving attackers free to dwell in the environment for days, weeks, or months. Businesses need to stop these “silent failures” by finding and removing attackers quickly.

To prevent silent failures, an EDR solution needs to provide continuous and comprehensive visibility into what is happening on endpoints in real time. Businesses should look for solutions that offer advanced threat detection and investigation and response capabilities, including incident data search and investigation, alert triage, suspicious activity validation, threat hunting, and malicious activity detection and containment.

. Managed threat hunting

Not all attacks can be detected by automation alone. The expertise of security professionals is essential to detect today’s sophisticated attacks.

Managed threat hunting is conducted by elite teams that learn from incidents that have already occurred, aggregate crowdsourced data, and provide guidance on how best to respond when malicious activity is detected.

4. Threat intelligence integration

To stay ahead of attackers, businesses need to understand threats as they evolve. Sophisticated adversaries and advanced persistent threats (APTs) can move quickly and stealthily, and security teams need up-to-date and accurate intelligence to ensure defenses are automatically and precisely tuned.

A threat intelligence integration solution should incorporate automation to investigate all incidents and gain knowledge in minutes, not hours. It should generate custom indicators of compromise (IOCs) directly from the endpoints to enable a proactive defense against future attacks. There should also be a human element composed of expert security researchers, threat analysts, cultural experts, and linguists, who can make sense of emerging threats in a variety of contexts.

Endpoint Security vs. Antivirus: What Is the Difference?

Antivirus software helps businesses detect, eliminate, and prevent malware from infecting devices. Antivirus solutions are installed directly on endpoint devices, such as laptops, PCs, network servers, and mobile devices. These solutions detect malware by scanning files and directories to discover patterns that match the definitions and signatures of a virus. They can also only recognize known threats and must be updated to detect the latest malware strains.

There are several significant differences between endpoint protection and antivirus software.

1. Device coverage: Traditional antivirus programs are designed to protect one single device, such as the antivirus programs placed onto laptops to keep them secure. Endpoint security solutions, on the other hand, look to protect all of the connected devices across an entire enterprise network.
2. Protection from threats: Antivirus solutions protect businesses from malware that is included within the businesses’ database of known threats. But sophisticated threats typically do not feature a traditional signature, which could leave businesses vulnerable. Endpoint security solutions take a more holistic view that protects businesses from threats such as data loss, fileless and signatureless malware, and phishing attacks in addition to known risks.
3. Continuous protection: Antivirus solutions use a signature-based detection process to discover and protect businesses from potential risks. This means if a user has not updated their antivirus program, then they could still be at risk. In contrast, endpoint security solutions connect to the cloud and update automatically, ensuring users always have the latest version available.
4. Advanced internal protection: Traditional antivirus programs can block malware, but they do not prevent employees from putting sensitive data on a USB drive and stealing it from the organization. Endpoint solutions offer greater protection from threats like data loss and data leakage through technologies like data encryption and data access controls.
5. Admin control: Antivirus solutions relied on users manually updating the software in order to keep it in line with new malware risks. But endpoint solutions provide interconnected security that moves the admin responsibility to the IT or security team. This removes the risk of human error putting end-users’ devices at risk.
6. Enterprise-wide control: Traditional antivirus solutions typically only notify a user when a threat is detected. The risk will then need to be analyzed and investigated in person by a security professional. But endpoint security solutions provide a centralized portal that enables admins to monitor activity, install, configure, patch, and update software, investigate any suspicious traffic, and resolve issues remotely.

Conclusion

Endpoint security is a critical component of overall cybersecurity. By implementing a comprehensive endpoint protection strategy, organizations can significantly reduce the risk of cyberattacks and protect their valuable assets.

Endpoint security is the cornerstone of a robust cyber defense strategy. As the primary entry points for cyberattacks, endpoints—including laptops, desktops, mobile devices, and servers—are increasingly targeted by sophisticated threats. Protecting these devices is paramount for safeguarding sensitive data, maintaining business continuity, and preserving organizational reputation.

While endpoint security solutions have advanced significantly, the threat landscape continues to evolve. To effectively mitigate risks, organizations must adopt a layered approach, combining multiple security technologies and practices. This includes robust endpoint detection and response (EDR), advanced threat protection, data loss prevention (DLP), and user education.
