Organizations can guarantee the resilience of their remote workforce and protect corporate data by proactively addressing potential risks.
In this article, we will delve into the intricate world of remote work security, exploring best practices, practical strategies, and tools for establishing a robust defense against emerging threats. We’ll discuss various measures to reduce remote working security risks, including secure network connections, authentication, encryption, employee training, and compliance.
Why is remote work security important?
Remote work security is crucial for protecting both employees and businesses against data breaches and security threats. When employees work remotely, they rely on personal devices and networks, which are often more vulnerable to attacks than corporate networks.
Additionally, remote employees may be less aware of security risks, making them more susceptible to scams and phishing attacks. By employing reliable security measures, businesses can effectively protect their employees and data from these threats.
Remote work security is vital for mitigating cyber risks, ensuring business continuity, and preserving privacy. It allows organizations to comply with data protection regulations and maintain trust and reputation.
8 pillars of remote work security
Protecting remote work environments necessitates a comprehensive approach based on key pillars. These pillars represent fundamental components and practices that safeguard sensitive data, protect against security risks, and promote secure remote work operations. Let’s explore these essential pillars in detail.
1. Secure access
Secure access ensures that authorized individuals can safely connect to remote systems and resources. Security tools such as identity and access management (IAM) and multi-factor authentication (MFA) reinforce secure access for remote workers.
2. Endpoint security
In a remote work setup, endpoint security is of utmost importance as employees utilize different devices to access company resources. Administering broad measures to safeguard against cyberthreats, including firewalls, antivirus software, and regular software updates, protects devices from malware, viruses, and other malicious activities.
Endpoint security works hand in hand with secure access. As secure access is granted, data is transferred across diverse endpoints. This ranges from IoT devices and smartphones to BYOD and partner-managed devices, as well as from on-premises workloads to cloud-hosted servers, all of which increase the overall attack surface. Maintaining vigilant protection is necessary to counteract any malicious attacks.
3. Cloud-based data security
Cloud-based data security services block unauthorized users from accessing the business’ data network. This technology enables remote user access management, including adding or revoking privileges, without hardware input.
A key advantage of cloud-based access management systems over traditional cybersecurity systems is their cost efficiency, as they eliminate the need for extensive infrastructure investments. Network administrators regulate cybersecurity restrictions and permissions within cloud-based access management systems.
4. Secure network infrastructure
Secure network infrastructure facilitates reliable communication between remote workers and company resources. A properly configured network infrastructure guarantees that remote connections are established through safe protocols, such as virtual private networks (VPNs) or secure remote access solutions. It includes administering firewalls and intrusion detection systems to defend against unauthorized access and external threats.
Network monitoring is an integral part of secure network infrastructure, enabling continuous observation and analysis of network traffic and activities.
5. Data protection
Protecting data from unwanted access, exposure, or revision is an indispensable aspect of remote work security. This encompasses encrypting data at rest and during transit, safeguarding it from interception, compromise, or theft. Data protection also covers data loss prevention (DLP), which stops unauthorized disclosure of sensitive information.
Together, these measures form a reliable foundation for remote work security, ensuring data safety, regardless of its location or mode of transmission.
6. Data backup
Data backup is another key factor of remote work security. When remote employees use personal devices and networks, the risk of data loss or corruption increases. Data backup strategies protect files from hardware failure, accidental deletion, cyberattacks, and other unforeseen events. These strategies involve regularly duplicating and storing data in separate locations.
In the event of a security breach or data loss, having recent backups allows organizations to restore lost or compromised data and reduce downtime. Data backup maintains data integrity, availability, and recovery. It protects sensitive information and reduces the impact of potential security threats in the remote work environment.
7. Security awareness and training
Regular security awareness and training sessions reinforce good security habits and keep remote workers informed about emerging threats. Training sessions educate employees about security risks and how to protect themselves and the organization. Security training should cover phishing, social engineering, and password security topics.
8. Incident response and management
An effective incident response and management framework outlines the processes, roles, and responsibilities for detecting, analyzing, and responding to security breaches in a remote work environment. This lets organizations quickly identify and contain security threats, minimize their impact, and restore normal operations.
Requirements of securing remote workforces today
Remote workforce security is a top priority for businesses of all sizes. Some of the key requirements for securing remote workforces include protected networks, reliable access, endpoint management, clear policies, software management, and private workspaces.
Protecting networks for remote workforces prevents unauthorized access, data breaches, and other cyberthreats. Organizations need to establish secure networks for remote workers through VPNs, network segmentation, firewalls, network monitoring tools, and regular updates and patching.
Reliable remote access and authentication
Organizations must provide secure remote access mechanisms that encrypt connections between remote workers and company resources. In addition, they should use MFAs to verify user identities through multiple factors. MFAs make it more difficult for unwanted users to access data. As a result, remote access is safe, and only authorized individuals can connect to the company’s systems.
Companies should deploy mobile device management (MDM) or endpoint management solutions to monitor and manage company-provided devices remotely. Endpoint security involves enforcing security policies, tracking devices, and performing remote wipes or data encryption in case of loss or theft.
Clear security policies
Communicating concise and clear remote work security policies and guidelines is another requirement for better security. Security policies should cover device usage, password complexity, data handling, software installation, and incident reporting. Organizations must also regularly review and update policies as needed.
Software and applications monitoring and management
For enhanced company-provided device security, organizations should utilize practices for monitoring and managing software and applications. This includes preventing unauthorized installations, enforcing software allowlisting, and regularly applying patches to address vulnerabilities.
Private physical workspaces
Remote workers should have private workspaces to safeguard devices against physical theft. Employees can also use privacy screens to prevent shoulder surfing and must securely store physical documents containing sensitive information.
Top remote work security risks for businesses
Distributed enterprises and their employees should proactively acknowledge remote work security risks such as phishing, malware, and unsecure connections. This way, they can gain a better understanding and take necessary steps to address these risks, ultimately streamlining business operations.
Remote work exposes employees to a higher risk of falling victim to phishing attacks due to using personal devices and operating outside corporate security measures. Cybercriminals perform phishing attacks to steal sensitive data, such as login credentials, through common communication channels like email or chat.
More and more remote workers are using personal devices for work, meaning devices with access to corporate data and resources may have unapproved apps installed for non-work-related browsing. This creates an ideal environment for malware to infect these devices and use them as a foothold for attacking corporate resources.
Unsecured network connections
Remote workers who use unsecured network connections are at risk of several dangers, including man-in-the-middle (MITM) attacks, data interception, unauthorized access, and privacy breaches. These risks expose sensitive data to unauthorized individuals, which could lead to data leaks, compromised devices, and privacy violations.
Weak endpoint security
Devices for remote work, like laptops or smartphones, might not have sufficient security measures to safeguard the business. This can be due to outdated software, missing patches, or the absence of strong antivirus and anti-malware solutions. These vulnerabilities significantly raise the likelihood of malware infections, data breaches, or unauthorized access to corporate resources.
Unauthorized access and insider threats
Remote work environments can be susceptible to unauthorized access if employees fail to implement strong authentication measures or if credentials are exposed. Furthermore, remote employees with access to sensitive data may unintentionally or intentionally compromise security, leading to data exposure or unauthorized sharing of confidential information.
Data leakage and loss
Data leakage and loss also pose a security risk in remote work environments. Remote workers may inadvertently expose sensitive information through misconfigured cloud storage, insecure file sharing, or unsecured networks. Using personal devices and the lack of physical security measures heighten the risk of data breaches. Data loss can also occur due to device theft or physical damage.
Weak password security
Weak passwords represent another widespread security risk in remote work arrangements. Some employees may use passwords that are easy to guess in their efforts to remember multiple passwords or due to complacency. Weak passwords that lack complexity and are open to brute force attacks or password cracking techniques. They undermine overall security, allowing unauthorized individuals access to sensitive information and compromising data confidentiality.
Lack of training in security best practices puts remote employees at a higher risk of exposing their companies to numerous security threats. Without proper training on identifying phishing attempts, using strong passwords, or secure file sharing, employees may unwittingly jeopardize data security.
Compliance and regulatory risks
Organizations, even with remote work arrangements, must adhere to specific laws, regulations, and industry standards. When employees work remotely, they may handle sensitive data or access systems subject to regulatory requirements such as data privacy, security, or confidentiality.
In a remote work environment, compliance challenges may arise due to the distributed nature of work, varying regional regulations, and lack of direct oversight and control over remote employees.
Lack of incident response preparedness
Compared to traditional office settings, remote work environments may be slow to detect and respond to security incidents. Without a well-defined incident response plan, businesses may find it challenging to successfully contain the damage of security breaches.

Applications and tools to secure remote workforces
Now that we’ve tackled the remote working security risks and the best practices to prevent them, let’s talk about the applications and tools needed to secure remote workforces, from zero trust and MFA to endpoint detection and backup.
Zero Trust security solutions
Zero trust security solutions are valuable for remote work as they provide a strong security framework to protect resources and data in distributed environments. In a zero trust model, all users and devices are considered to be potentially hostile, and access to resources is strictly controlled based on user identity and device security posture.
This principle prevents unauthorized access to sensitive data even if a user’s credentials are already compromised. Zero trust security tools are instrumental in delivering secure and granular access controls for both users and devices, regardless of their physical location.
Here are some common zero trust network security tools used for remote work:
- Virtual private networks (VPNs): These tools fortify remote work security by creating encrypted connections, allowing remote workers to securely access internal resources over the internet. VPNs offer an additional layer of defense by protecting sensitive information with encryption protocols, ensuring the privacy and integrity of remote communications. Some of the most widely-used VPNs for businesses are NordVPN, Perimeter 81, and TunnelBear VPN.
- Identity and access management (IAM): IAM solutions are zero trust security tools that manage user identities, using powerful authentication methods and controlling access to resources based on user roles and policies.
- Zero Trust Network Access (ZTNA) tools: ZTNA tools support secure access to specific applications and resources based on user authentication and contextual factors. This means that users are only granted access to the applications and resources they need to do their jobs, and that access is constantly verified based on factors such as the user’s location, the device they are using, and the security posture of the device. Some popular ZTNA tools include Okta, Zscaler Private Access, and Prisma Access by Palo Alto Networks.
Businesses employ MFA solutions to strengthen their defenses against credential theft and user impersonation. MFA requires remote workers to undergo different verification processes to access on-premises or cloud-based applications or systems. This can include giving a combination of credentials like a password and a one-time, short-lived SMS code.
Leading MFA solutions incorporate adaptive authentication, which balances strong security measures with user convenience. Adaptive authentication uses contextual information, such as the user’s location or device type, along with predefined business rules, to determine the appropriate authentication factors for a specific user in a given scenario.
Organizations boost data protection by employing encryption methods within and beyond the corporate network. Encryption tools convert sensitive data into an unreadable format, making it unintelligible to unauthorized individuals, whether stored (at rest) or transmitted (in transit). These tools utilize cryptographic algorithms to scramble the data, and only authorized parties possessing the encryption key can decrypt and access the information.
Endpoint Detection and Response (EDR) solutions
EDR tools track and analyze endpoint activities, including remote devices, to detect and respond to potential security threats. They can be used to identify malicious activity, malware infections, unauthorized access, and data exfiltration. EDR tools are also used to investigate security breaches and identify the source of attacks.
Endpoint protection tools
Endpoint protection solutions, also known as endpoint privilege management solutions, strengthen security by eliminating unnecessary local administrator privileges from remote worker devices and containing threats at the endpoint. These are deployed alongside other endpoint security measures, forming part of a comprehensive defense-in-depth strategy. The endpoint protection process involves installing firewalls for monitoring and controlling network traffic and using antivirus and anti-malware software.
Endpoint backup software
Endpoint backup software protects remote devices like laptops and mobile devices from data loss caused by hardware failures, accidental deletions, or security incidents. It ensures regular data backups and makes data recoverable. The endpoint backup process entails securely duplicating and storing data from network endpoints, including laptops, desktops, and servers. Cloud-based endpoint backup solutions have become popular in enterprises because they deliver thorough protection for both critical and non-critical data.
Single Sign-On (SSO) solutions
SSO solutions enhance user experiences and reduce the likelihood of security breaches associated with weak passwords or password mishandling. SSO lets remote workers access all their business applications and services using a single set of credentials. With SSO tools, businesses simplify the authentication process, enabling a more secure and efficient user experience.
User and Entity Behaviour Analytics (UEBA) software
UEBA software flags unusual or suspicious activities performed by remote workers or their devices. By analyzing factors such as login patterns, application usage, data access behavior, and network traffic, UEBA solutions can spot deviations from normal behavior that may indicate security incidents, insider threats, or unauthorized access attempts.
Network Traffic Analysis (NTA) tools
NTA solutions provide organizations with visibility into network activities to identify suspicious or malicious behavior. This includes detecting anomalous network traffic, such as unauthorized access attempts, which may indicate a security incident. NTA solutions also give organizations the ability to observe network traffic from remote workers’ devices, including traffic generated by VPN connections. As a result, cybersecurity teams can find potential threats like network-based attacks and respond on time.
These are software programs that help remote workers generate, store, and manage reliable and unique passwords for their various online accounts and services. By securely storing passwords in an encrypted vault, password managers unburden users from remembering multiple complex passwords.
Password managers also provide the convenience of automatically filling in login credentials, minimizing the risk of weak or reused passwords. These applications allow individuals and businesses to store and manage passwords in one secure location protected by a master password. With a password manager, users only need to remember their master password to gain access.
Secure collaboration and communication tools
Collaboration and communication solutions are widely used tools by remote workers. These applications equip distributed teams with platforms for sharing files, working together on projects, and connecting with colleagues.
Secure collaboration and communication tools often facilitate private messaging, file encryption and sharing, and document collaboration. However, other collaboration tools, such as remote desktop software, contribute to protected remote collaboration by employing SSL/TLS encryption protocols to establish secure connections between the local and remote systems. Some remote desktop software also offers the ability to record remote sessions or maintain audit logs. This feature lets cybersecurity teams review session activities, track changes, and investigate suspicious actions.
Security Information and Event Management (SIEM) systems
SIEM systems boost security by collecting and analyzing security event data from multiple sources. They provide centralized visibility to detect and alert on threats and anomalies in real-time, enabling quick incident response. SIEM systems monitor compliance, analyze user behavior, and safeguard sensitive data.
Email security tools
Email security tools protect remote employees against email-based threats. They filter spam, detect and block phishing attempts, scan for malware, prevent data loss, and offer encryption. These tools ensure that employees are safe from malicious content, phishing scams, and accidental data leaks, maintaining the security and integrity of email communications in remote work environments.
