INTRODUCTION
The digital transformation era has brought significant advancements in technology, communication, and connectivity, reshaping how businesses operate and how individuals interact with the world. This progress has enabled greater efficiency and convenience, yet they have also introduced a range of security challenges. Among these, the rise of cyber threats has emerged as a critical concern for organizations worldwide.
The increasing adoption of remote work has further complicated the cybersecurity landscape. While remote work offers benefits such as increased flexibility and access to a diverse talent pool, it has also expanded the attack surface for cybercriminals. Remote work environments often lack the robust security measures of centralized corporate networks, making them vulnerable to a variety of cyber threats. The use of personal devices and public networks in remote work settings introduces new
vulnerabilities, creating opportunities for cyber attackers to exploit. The aim of this paper - to examine the trends in cyber threats, the security challenges, and the security enhancement methods that can be implemented in remote work environments.
MAIN PART. TRENDS IN CYBERATTACKS AND SECURITY CHALLENGES IN REMOTE ENVIRONMENTS Remote work is becoming a permanent fixture for many organizations. Companies are increasingly adopting flexible work arrangements, leveraging technology to maintain productivity and collaboration. According to statistics [1], about one in five (19,5 %) workers teleworked or worked at home for pay in August 2023. The technology sector had the highest proportion of remote workers globally in 2023, with over 67% of employees in the sector working from home or in a location other than their place of work [2].
This trend has led to the decentralization of corporate networks, where employees access company resources from various locations and devices. While this shift offers numerous benefits, it also expands the attack surface for cybercriminals. Statistics indicate a yearly increase in both the number of data breaches and the resulting financial damage (fig. 1).

ability to maintain business continuity, it also introduces distinct security risks. These risks primarily stem from the decentralized nature of remote work, where employees connect to corporate systems from various locations, often using personal devices and unsecured networks, making organizations more vulnerable to cyberattacks.
One of the most critical challenges in remote work is the expanded attack surface. In traditional office environments, security measures are concentrated within a controlled network perimeter. IT teams can easily monitor activity, enforce security policies, and secure corporate assets behind firewalls and security gateways. In remote work settings, the attack surface widens significantly as employees connect to corporate systems from home or other off-site locations [4].
Corporate office networks typically implement robust security measures, including firewalls, intrusion detection systems (IDS), and virtual private networks (VPN). Remote workers' devices lack of network security and don't have such sophisticated protections in place on their home networks. Many home routers are inadequately secured, with default passwords and outdated firmware, creating opportunities for cybercriminals to infiltrate them.
Unsecured or poorly secured home networks make it easier for attackers to conduct man-in-the-middle (MITM) attacks, where they intercept and manipulate communications between employees and corporate systems. Home networks may have multiple connected devices (IoT devices, smart home systems, etc.) that could serve as additional points of vulnerability.
Endpoint security also becomes a major concern. In many cases, remote employees use personal devices that may not comply with the organization's security policies. These devices are more susceptible to unauthorized access because they lack enterprise-level protection mechanisms such as endpoint detection and response solutions, encryption, and regular updates. Without centralized control, IT teams face significant challenges in ensuring that all devices used to access corporate networks are adequately secured. In the event that a personal device is compromised, it could become a gateway for attackers to penetrate corporate systems.
Remote workers are more vulnerable to phishing and social engineering attacks, which exploit human error to gain unauthorized access to sensitive information. Phishing remains one of the most common attack vectors in remote work environments. Attackers craft convincing emails or messages, often pretending to be from trusted sources such as IT departments or company executives, in an attempt to trick employees into revealing login credentials or downloading malicious software.
SECURITY ENHANCEMENT MEASURES AND PRINCIPLES IN REMOTE
ENVIRONMENTS
As the cyber threat landscape continues to evolve, particularly with the rise of remote work, organizations must adopt comprehensive and proactive security measures to safeguard their data and systems. Traditional perimeter-based security models are no longer sufficient, especially in decentralized environments where employees access corporate resources from diverse locations and devices.
The Zero Trust model operates on the premise of «never trust, always verify». This framework requires that all access requests, whether originating from inside or outside the organization, be authenticated, authorized, and encrypted [5]. Zero Trust is especially critical in remote work environments, where employees frequently access corporate resources from multiple devices and locations. According to Microsoft [6], this model has gained prominence as a robust security framework (table 1).
Table 1. Comparison of Traditional security vs. Zero Trust security
Aspect Traditional security Zero Trust
Access control Trust based on network location. Trust based on identity and behavior.
Perimeter protection Strong firewall, weak internal defenses. No implicit trust, every access verified.
User authentication Single sign-on (one-time verification). Continuous verification (MFA, RBAC).
Lateral movement Easier for attackers once inside. Micro-segmentation prevents lateral moves.
Data encryption Often limited to external threats. Encryption of data both at rest and in transit.
Multi-factor authentication (MFA) approach is a foundational element of Zero Trust. It requires users to present multiple forms of identification, such as a password and a time-sensitive code sent to a mobile device. The method significantly reduces the ISSN 3034-2627 12 coldsciencepublisher.com
likelihood of unauthorized access even if login credentials are compromised. According to a study by Microsoft researchers [7], the implementation of MFA can block over 99,9% of account compromise attacks.
Role-based access control (RBAC) limits users' access to data and systems based on their roles within the organization. By restricting access to only the resources necessary for their job, RBAC minimizes the attack surface. In remote environments, RBAC ensures that remote employees or contractors are only granted the minimum permissions required to perform their tasks, preventing lateral movement within the network in case of a breach.
To protect sensitive information, all data, whether being stored on remote devices or transmitted between endpoints, must be encrypted. Encryption ensures that even if data is intercepted or a device is compromised, it remains unreadable to unauthorized users. Many organizations are increasingly adopting advanced encryption standards (AES) to bolster data security. By encoding data in such a way that only authorized parties can read it, encryption mitigates the risk of data breaches and loss of sensitive information.
End-to-end encryption (E2EE) ensures that data is encrypted at its point of origin and can only be decrypted by the intended recipient. E2EE is especially useful for protecting sensitive communications and file transfers across unsecured networks, such as public Wi-Fi. Many popular collaboration tools, like Microsoft Teams and Zoom, have implemented E2EE for video calls and document sharing to enhance security [8].
As more organizations shift to cloud-based services for remote work, securing cloud infrastructure becomes paramount. Solutions like cloud access security brokers (CASB) help organizations monitor and enforce security policies in cloud applications, ensuring compliance and data protection. Companies can use server-side encryption (SSE) to protect data stored in the cloud. With the advancement of artificial intelligence and machine learning technologies, it is becoming increasingly feasible to utilize these tools to enhance user data protection and strengthen cybersecurity measures in remote work environments [9, 10].
Endpoints, such as laptops, smartphones, and tablets used by remote workers, are common targets for cyberattacks. Strengthening the security of these devices is essential to preventing breaches. Implementing mobile device management (MDM) tools allows organizations to monitor and control remote devices. These tools can enforce security policies, such as password strength, and remotely wipe data if a device is lost or stolen. Continuous monitoring of endpoint activity can also help detect and mitigate potential threats before they escalate.
Cyber attackers often exploit vulnerabilities in outdated software. Ensuring that all remote devices have the latest security patches and software updates reduces the risk of malware infections and unauthorized access. Automated patch management systems can be deployed to streamline this process across remote environments. Endpoint Detection and Response (EDR) solutions provide real-time monitoring and analysis of endpoint activities. By detecting abnormal behavior patterns or unusual access attempts, EDR systems can quickly identify and isolate threats before they compromise the network. This is particularly crucial in a decentralized workforce where traditional perimeter defenses may not suffice.
Human error remains one of the weakest links in cybersecurity. Regular training programs that teach employees how to identify phishing attempts, malicious attachments, and suspicious links are vital. Simulated phishing exercises can help reinforce this training and measure employees' ability to recognize threats. Weak passwords are often a gateway to larger security breaches. Employees should be encouraged to use password managers to generate and store strong, unique passwords. Additionally, password policies requiring regular changes and restrictions on reuse should be enforced across the organization.
As remote work continues to reshape the cybersecurity landscape, organizations must take a proactive stance in strengthening their security measures. From Zero Trust frameworks and encryption technologies to robust endpoint protection and employee education, these measures collectively create a resilient defense against modern cyber threats.
