Introduction: The Need for Cybersecurity in Remote Work

As IT managers in Hong Kong, the shift towards remote working has presented numerous challenges for managing cybersecurity. The concept of working ‘from any device and anywhere’ has been around for a while, but the COVID-19 pandemic has amplified the security challenges associated with remote working.

The Urgency of Connecting Remote Workforces

At the onset of the pandemic, organizations faced the urgent task of connecting a sudden remote workforce, many of whom lacked prior experience working outside of the office environment. Providing secure access to both on-premises and cloud-based services became vital, alongside access to native mobile applications. Traditional VPNs alone proved insufficient for daily operations and required further enhancement with complementary tools and techniques.

Embracing Zero-Trust Approach

Adopting a zero-trust approach emerged as a priority for all organizations, emphasizing the principle of ‘never trust, always verify’. Identity and Access Management (IAM) plays a critical role in implementing zero-trust principles. Provisioning Single Sign-On (SSO) with Multifactor Authentication (MFA) is imperative, requiring frequent confirmation of user identities through various methods such as OTP, SMS, biometrics, or voice recognition. Balancing privacy and security remains a delicate matter when confirming identity on personal devices.

Implementing Least Privilege Access Authorization

Least privilege access authorization grants users minimal access required for their roles. Regular access and privilege reviews and certifications ensure this principle applies consistently to all users. Exceptions may arise, necessitating elevated system access temporarily. IDAM tools can enforce risk-based or policy-based access, taking factors like location and network access points into consideration.

Securing All Organization Endpoints and Applications

Securing all organization endpoints and applications is equally important. Endpoint management solutions facilitate controlling all devices and applications, whether user devices, IoT devices, or devices directly linked to the corporate network, such as printers and servers. Collaborating virtually amidst widespread remote work prompted companies to implement collaboration software on devices, often presenting new challenges. Company device management involves maintaining up-to-date operating systems, applications, secure configurations, and restricting system access based on location. Mobile device management (MDM) enables companies to manage tablets and smartphones effectively.

Managing Bring Your Own Device (BYOD)

Managing Bring Your Own Device (BYOD) poses distinct challenges regarding device and access security responsibilities. Protection of sensitive data stored on personal devices represents one of the greatest hurdles. Implementing an endpoint management solution, such as Microsoft Intune, is crucial for managing all devices and ensuring they comply with organizational standards. Establishing clear guidelines concerning personal device usage, restricted apps, accessing company data, and mandating the use of the company VPN client for on-premises service access enhances overall security. Adopting a zero-trust mindset is indispensable for safeguarding organizational assets against diverse threats. Despite varying geographical locations, zero-trust policies are universally applicable and represent sound business practice.
