Businesses continue to adapt to remote work, and with increased cloud adoption, understanding and addressing endpoint security threats has become crucial. A report revealed that the global cost of cybercrime is increasing and will exceed around USD 10.5 trillion annually by 2025. This pessimistic statistic emphasizes the importance of effective endpoint security; a key pillar of organizational health and resilience.
Today, organizations need to turn their focus on security from the traditional approach of perimeter-based solutions to a holistic approach that will protect every device connected to an organizational network.
In this extensive article, you will learn about endpoint security, its importance, and the dangers organizations encounter in this sector. Further, it will cover the major endpoint security threats, understand the risks they pose, and the possible ways of protection. Furthermore, we will discuss how effective solutions such as SentinelOne contribute to the overall protection of your organization’s endpoints.
What is Endpoint Security?
Endpoint security involves securing the endpoints used by devices that connect to a corporate network from many possible kinds of external attacks. These can be laptops, desktops, mobile devices, servers, or IoT devices—all of which may turn out potentially to be an entry point for cybercriminals desiring an opportunity concerning those flaws on the network.
Organizations face multiple endpoint security threats as a result, it becomes necessary to ensure that all devices making network connections are at a defined security compliance level. It helps protect organizations from unauthorized access, prevents data breaches, and maintains the integrity of a whole system.
The shift to remote work, together with the bloom in the use of mobile devices, has increased this requirement for endpoint security even more. Security policies in today’s complex digital environment have no choice but to secure every device that connects to the network, making endpoint security one very intrinsic need for any organization.
Need for Endpoint Security
The need for comprehensive endpoint security in today’s day and age is, therefore, very important. Several factors contribute to this critical need:
- Advanced cyber threats: With the growing complexity of cyber threats, traditional security measures are proving almost useless against cyber criminals. Indeed, several recent reports highlight that many organizations have suffered breaches attributed to unresolved vulnerabilities—a clear case for vigilance and timely updates in security protocols.
- Remote Work and BYOD Policies: The trend to remote work and Bring Your Own Device policies is on the rise, thereby expanding the attack surface of organizations. Indeed, a good number of firms have reported security occurrences around remote work environments that raise the risks associated with a distributed workforce.
- Data Breach and Monetary Loss: The security breach of an endpoint is capable of causing immense monetary loss to an organization besides destroying its good name. On average, a data breach costs 4.88 million dollars for the year 2024, where a major part is from the failures of the security at the endpoint. The cost here considers direct monetary loss and regulatory fine along with legal fee losses of customer trust due to a data breach.
- Compliance Requirements: There are many industries that fall under very strict compliance regulations. Those very regulations require strong measures of endpoint security to be put in place in order to keep sensitive data in line. Thus, failure to comply can have very serious consequences. For instance, when GDPR is breached, fines can amount to up to €20 million or 4% of annual global turnover – whichever is greater.
- Changing threat landscape: The cybersecurity threat landscape is dynamic, and the organization faces new malware variants, ransomware, and APTS almost every day. Your organization must be proactive on these types of threats to be able to protect digital assets successfully.
What are Endpoint Security Threats?
Endpoint security threats can be defined as any action that takes place on the devices affiliated with the network without the permission of the system owner or controller. These threat types are categorically serious since there are a wide range of them, such as Malware, Phishing and other social engineering, Zero-day attacks, Denial of service attacks, network intrusion, insider threats, and ransomware attacks. Any of the above threats lead to loss of personal identifying information, disruption of services, and significant monetary losses.
Impact of Endpoint Security Threats
The consequences of endpoint security threats can be very serious, such as data breaches, loss of revenue, reputational damage, legal implications, and many more. The threats have evolved in complexity, making them hard to detect with traditional security measures. With this, it is important to understand the severity of these threats so that prevention strategies are implemented within organizations that are vulnerable to security risks.
Top 8 Endpoint Security Threats and Prevention Strategies
First in the line of endpoint security risk management is the identification of common threats and finding strategies to prevent them. Here are the top eight endpoint security threats, along with actionable measures to help counter these:
#1. Malware
Malware includes a wide variety of malicious software, such as viruses, worms, Trojan horses, ransomware, spyware, and others. Although all are implemented very differently, each utilizes different methods of infection—but shares the common trait of attachment to other actual files while delivering harmful payloads. The effects of having malware infection are detrimental, which may lead to loss of data, unauthorized access, system failure, and may lead to exploitation that costs extensively.
How to prevent this threat?
- Use only reliable programs, such as anti-virus and anti-malware software, updating it regularly and scanning all the files of the computer.
- Increase safety measures as it pertains to browsing the Internet and handling emails.
- Make sure that all the software installed is effectively updated with all the latest security patches available.
- Select robust and highly distinct passwords, and never neglect MFA (Multi-Factor Authentication).
- Invest in conducting more security awareness training for employees to reduce the risks that come with day-to-day operations.
#2. Phishing Attacks
Phishing emails are those which involve the use of social engineering to trick targets out of their personal information and passwords, or download malware; this is done using emails that look legitimate, appearing to be from a trusted source. This can create a variety of problems: data loss, financial theft, identity fraud, and larger issues such as malware infections.
How to prevent this threat?
- Establish comprehensive employee training solutions that would help detect phishing processes.
- Employ up-to-date capabilities of the email filters to automatically identify and prevent receipt of threatening emails.
- There should be measures that must be followed when it comes to the authorization of sensitive information requests, particularly through emails.
- Use Domain-based Message Authentication, Reporting & Conformance (DMARC) to fight fake emails.
- Phishing tests should be done often to increase awareness as well as the competence of the employees in responding to the tests.
#3. Social Engineering Attacks
Social engineering attacks make people reveal sensitive information or give access to unauthorized persons by using trust and psychological tricks. It can be noted that most of these attacks can reach past technical security measures and result in unauthorized access or data theft, monetary losses, and disruption of business operations. This makes them hard to avoid, especially when they are programmed to take advantage of people’s weaknesses.
How to prevent this threat?
- The specific security awareness training that has to be implemented should entail the techniques in social engineering.
- It is recommended to have strong identification procedures before a person gains permission to access a certain type of system or information.
- Ensure all critical systems require multi-factor authentication to block all the multiple forms of malware at the entrance.
- Promote a security awareness culture that will help employees raise any concern with any perceived anomaly.
- Access control policies should be updated from time to time in order to be in line with current security standards and practices.
#4. Zero-Day Exploits
Zero-day exploits are among the most dangerous cyber threats. They get leveraged on the vulnerabilities within software that a vendor has not identified and, hence, has no patches yet. It encourages unauthorized access to systems, resulting in severe data breaches, intellectual property theft, or system compromise by cybercriminals.
Such attacks are labeled as “zero-day” attacks as the developers have zero time to respond. These kinds of attacks can be really dangerous because they may remain undetected for long periods; hence, an attacker can have stable, persistent access to multiple compromised systems.
How to prevent this threat?
- Create an effective patch management policy that ensures the application of any available patches when they become available for systems.
- Use endpoint detection and response tools to watch for abnormal behavior that could signal the presence of a zero-day exploit.
- Deploy SIEM solutions to analyze log data for possible patterns of ongoing attacks.
- Implement network segmentation to limit the impact of potential exploits.
- Do penetration testing and vulnerability assessments often to help close off such avenues before they are used to exploit a system.
#5. Denial of Service (DoS)
Denial-of-Service (DoS) is a form of attack that overloads the system, service, or network to deny resources to its users. A more sophisticated version is Distributed Denial-of-Service (DDoS) attacks; a more compromised version sends multiple compromised systems to launch an attack, making mitigation hard.
Depending on their complexity, DoS attacks usually hide the activities of major threats. The reactions can be seriously disruptive to business functions, leading to financial losses, lack of productivity, and damage to the corporate reputation.
How to prevent this threat?
- Develop robust network security protocols with inbuilt firewalls and intrusion prevention systems for recognizing and barring attack patterns.
- Use CDNs to distribute the traffic among multiple servers and cushion the impacts of DoS attacks.
- Build and test incident response plans periodically to reduce downtime in case of an attack.
- Use network-monitoring tools to identify any traffic patterns that appear out of the ordinary and could potentially serve as a trigger to set off a DoS attack.
- Employ, when feasible, DoS mitigation services when the effects of the attacks seem cumbersome.
#6. Network Intrusion
Network intrusion is the term that is used in discussing incidences wherein some unauthorized individuals penetrate a network through the most likely vulnerabilities the network defenses contain. Once inside the system, they could steal sensitive data, deploy malware, or disrupt operations. These attacks can be quite damaging because they often go unnoticed until later, with attackers able to carry out the exfiltration of data or gather intelligence over time.
As a serious consequence, network intrusions tend to result in data leaks that are dramatic, theft of intellectual property, or even complete compromises of the system.
How to prevent this threat?
- Beef up network security with strong firewalls, encryption, and conduct periodic security audits.
- Update and patch devices in the network regularly to eliminate existing vulnerabilities.
- Implement network segmentation to reduce an attacker’s ability to move around the network.
- Emphasize and implement strong access controls and multi-factor authentication to safeguard sensitive data.
- Perform regular security audits and penetration testing to identify and fix potential vulnerabilities.
#7. Insider Threats
Insider threats are treated as a special class of cyber threat due to the threat source being the threat at the organization, employees, contractors, and such parties with legal access to systems and data. It could either stem from an intent to do something wrong, being malicious, or from careless actions that jeopardize organizational security.
This can be disastrous of all effects any organization can get from insider threats, all because the insider understands the systems and data of the organization.
How to prevent this threat?
- Apply the least privilege principle so that users possess no more access than required for their roles.
- Use UEBA tools to detect inherently odd behaviors indicative of a potential insider threat.
- Conduct continuous employee security awareness training on cyber risks and the ensuing repercussions from insiders.
- Implement data loss prevention solutions in the management and approaches to sensitive information transfer.
- Develop and enforce data-handling policies that stipulate how employees can use data and the consequences of any violations.
#8. Ransomware Attacks
Ransomware has topped the list of most proliferated and harmful forms of cyberattacks over the last few years. In the process, the malware uses encryption to lock away the files or even the whole system of a targeted victim, making them effectively unattainable. The attacker then demands a ransom, usually in the form of cryptocurrency, in exchange for the decryption key.
Ransomware-as-a-service models have seen a steady rise, making these attacks more sophisticated and bringing new problems to the doors of cybersecurity professionals in any given industry.
How to prevent this threat?
- Develop a full backup strategy with secure and offline storage to support the recovery of data without needing to pay a ransom.
- Implement next-generation endpoint security solutions that can identify and block ransomware even before the actual encryption of data takes place.
- Train employees to recognize and avoid the most common infection vectors for ransomware, starting with phishing emails.
- Use application whitelisting to prevent websites or illegitimate applications, including ransomware, from entering your system.
- Plan and regularly test a ransomware incident response plan so the organization can respond timely and accordingly if the worst happens.
