Secure Remote Access involves security measures or technologies intended to block unauthorized entry into an organization’s digital resources and safeguard against sensitive data leakage. It encompasses various approaches like VPN, multifactor authentication, and endpoint protection.
The evolving threat landscape and the surge in remote work prompted by the Covid pandemic have underscored the importance of secure remote access in today’s IT landscape. Achieving success in this area necessitates user education, enhanced cybersecurity policies, and the adoption of robust security practices.
How does Secure Remote Access work?
Ensure endpoint protection for all remote users and their devices – Securing endpoints in a datacenter is relatively straightforward compared to securing endpoints for remote users who frequently use multiple devices throughout the business day. All endpoint devices, whether PC, Mac, Linux, iOS, or Android, should have antivirus software installed. Security policies must mandate that all employees maintain up-to-date protection to access corporate resources. Provide guidance and support to employees as needed to help them establish secure access to the organization.
Minimize the attack surface from remote access – Deploying remote access can introduce risks to the organization, particularly with ransomware attacks that often target Remote Desktop Protocol (RDP) servers and exploit any available port for access. Avoid opening remote access ports unless firewalls are configured to only respond to known IP addresses authorized by system administrators.
Implement multifactor authentication (MFA) – Multifactor authentication (MFA) requires users to provide both a password and an authentication token, ensuring that only verified users gain access to corporate resources.
Utilize virtual private networks (VPNs) – Many remote users connect from insecure Wi-Fi or other untrusted network connections. VPNs mitigate this risk, but VPN endpoint software must be kept updated to prevent vulnerabilities associated with older software versions.
Regularize logging and security information tracking – Existing security information and event management (SIEM) tools may flag users logging in from home IP addresses as an anomaly during the Covid pandemic. Adjustments may be required in SIEM and geofencing/geo-blocking features in firewalls to accommodate employees logging in from various locations.
Educate users and contractors – With the rise of Covid-related cyber threats and phishing attacks, all employees and those accessing corporate resources should receive security and compliance training, emphasizing the importance of not clicking on unsolicited emails or links.
Update policies for remote workforce – Revise acceptable use policies to encompass employees’ home computing assets, such as computers, laptops, tablets, and smartphones. This includes ensuring that antivirus and VPN software on employee-owned devices are regularly updated.
What technologies are used for Secure Remote Access?
Secure remote access isn’t reliant on a single technology; rather, it’s an amalgamation of various technologies working together to furnish the requisite security for organizations when users operate from home or other remote locales. These encompass:
Endpoint Security – Involving software such as antivirus for endpoint devices, alongside policies dictating the utilization of remote devices within the organization’s systems. This may include activities like patch management and preventing the downloading or caching of crucial business information onto remote devices.
Virtual Private Network (VPN) – VPNs are widely favored for remote access as they enable users connecting via insecure remote Wi-Fi to establish a secure connection to a private network through encrypted tunnels.
Zero Trust Network Access (ZTNA) – ZTNA solutions operate on the principle of assuming zero trust regarding the security of connections, necessitating re-authentication before every transaction. This ensures higher security levels for the organization’s data and applications.
Network Access Control (NAC) – NAC regulates network access through a combination of tools like two-factor authentication (2FA), endpoint security solutions, and policy enforcement and education.
Single Sign-On (SSO) – SSO streamlines the authentication process by allowing users to access all their applications and resources with a single set of credentials.

Why is Secure Remote Access important?
While the prevalence of remote workers had been growing prior to 2020, the Covid pandemic significantly expedited the necessity for users to connect to corporate networks from various remote locations. For numerous organizations, the majority of inbound connections now originate from their employees’ home networks, thereby heightening risks for both the organization and the employees. Consequently, older, outdated security measures are insufficient for addressing the needs of a predominantly remote and mobile user base. The new security standard necessitates support for every user, regardless of the device they use or the network they connect from.
What are the benefits of Secure Remote Access?
A secure remote access strategy offers several advantages, including:
- Secure access from anywhere, on any device – Users can maintain the same level of secure access they had while working in the office. Access controls can be tailored to grant specific application and data access based on individual user roles and responsibilities. Given the anticipated continuation of remote work post-Covid, this remains a crucial benefit of a secure remote access strategy.
- Strong endpoint protection – Effective remote access relies on robust endpoint security. With users increasingly using multiple devices for work, it’s essential to ensure protection for laptops, tablets, and smartphones. Moreover, employee-owned devices should receive the same level of endpoint security as those provided by the organization.
- Safe internet browsing – Organizations heavily rely on web-based and internet-focused applications, necessitating protection for users even when they’re not connected to the organization’s on-premises resources. Secure remote access includes safeguards against web-based threats such as ransomware and phishing attacks.
- Increased security awareness – A mobile workforce presents new security challenges, many of which can be addressed through education. By reinforcing security policies and best practices, IT and security organizations can raise awareness and promote good cybersecurity hygiene among employees.
What are the security risks of remote access?
Remote access presents several security risks, including unauthorized access, data breaches, malware infections, and compromise of sensitive information. Here are the reasons why remote access can expose your network to these risks:
- VPN vulnerabilities: While Virtual Private Networks (VPNs) encrypt a user’s connection to a network, they are not immune to threats. Without robust protection for secure remote access, VPNs can be exploited by attackers to gain unauthorized access or steal data.
- Expanded attack surface: As organizations allow more devices to connect remotely, they increase the number of entry points for potential cyber attackers. This leads to an expanded threat surface, making the network more susceptible to attacks.
- Human error: Employees with limited security training may make mistakes such as neglecting to update devices, overlooking best security practices, failing to adhere to corporate security policies, or falling victim to phishing scams. However, these errors can result in serious consequences such as network breaches or data exposure.
- Phishing and malware: Cyber attackers exploit remote access by using phishing emails or malware attachments. Once a user clicks on deceptive links or downloads malicious files, attackers can establish a foothold in the organization’s network.
- Privileged access vulnerabilities: Users with privileged access to critical systems and data pose a risk if their remote connections are not adequately secured. Attackers can exploit these accounts to gain access to sensitive information, compromise security systems, and disrupt critical operations.
Conclusion
Secure Remote Access is crucial in today’s remote work environment. By utilizing technologies like VPNs and multifactor authentication, organizations can ensure secure connectivity for remote users while protecting against cyber threats. With robust security measures and ongoing user education, organizations can fortify their remote access capabilities and promote cybersecurity awareness. Secure Remote Access is not just a technology solution; it’s essential for adapting to remote work challenges and securing digital environments in today’s interconnected world.
