Cybersecurity best practices for remote work; how businesses and employees can stay ahead- Kolawole Joseph Ajiboye

By Rita Okoye

Remote work has redefined the security landscape, presenting both opportunities and new threats. The shift to digital workspaces has allowed businesses to operate with unprecedented flexibility, but it has also created vulnerabilities that cybercriminals are keen to exploit.

Software developer and cybersecurity expert, Kolawole based in the UK, who has supported many businesses in the development of secure software solutions that are robust, scalable, and compliant with industry standards. With a strong focus on protecting sensitive data and ensuring regulatory compliance, he helps organisations design and implement cybersecurity strategies that mitigate risks, prevent breaches, and safeguard critical assets speaks about the growing cybersecurity threat in remote work.

According to him, as a cybersecurity expert, the reliance on home networks, personal devices, and cloud-based collaboration tools has expanded the attack surface, making businesses and employees more susceptible to data breaches, phishing attacks, and ransomware incidents. Cybercrime has become a global crisis, with attacks escalating in both frequency and sophistication.

Reports from the World Economic Forum indicate that cyberattacks surged by 600 per cent during the COVID-19 pandemic, and the aftermath continues to expose new weaknesses in remote work environments. In Africa, cybercriminal activities are on the rise, with Interpol’s 2023 Cybercrime Report showing that phishing, ransomware, and business email compromise remain the dominant threats. Nigeria, South Africa, and Kenya collectively accounted for 70 per cent of reported cyberattacks on the continent. These figures highlight the urgent need for organisations to rethink their cybersecurity strategies and for employees to take a proactive role in securing their digital workspaces.

For the escalating cyber threats facing remote work; businesses continue to embrace hybrid and fully remote work models, cybercriminals are adapting their tactics to take advantage of security gaps. One of the most pervasive threats is phishing, which remains the most common entry point for cyberattacks.

According to Cybersecurity Ventures, over 90 per cent of all cyber incidents originate from phishing emails designed to manipulate users into disclosing sensitive information. These attacks have become more sophisticated, often mimicking legitimate business correspondence or targeting specific individuals through social engineering techniques.

Another alarming trend is the increase in ransomware attacks. In 2023 alone, global ransomware incidents surged by 73 per cent, with African businesses facing significant exposure. Ransomware involves encrypting an organisation’s data and demanding payment for its release. In many cases, businesses that fail to implement proper security controls find themselves at the mercy of cybercriminals, resulting in financial losses, operational downtime, and reputational damage.

Remote work has also amplified the risks associated with weak security practices, particularly in organisations that allow employees to use personal devices for work. Bring Your Own Device (BYOD) policies, if not properly managed, can introduce vulnerabilities such as malware infections, unencrypted data storage, and unauthorised access to corporate systems. This is especially concerning in Nigeria, where cybersecurity frameworks are still evolving, and businesses are often left vulnerable to data breaches due to lax security policies.

There are roles employers can do in strengthening cybersecurity businesses. They must take decisive actions to protect their remote workforce and corporate assets from cyber threats.

One of the most effective strategies is employee education and awareness. Human error accounts for 95 per cent of cybersecurity breaches, making regular security training an essential component of any organisation’s defence strategy. Employees must be trained to identify suspicious emails, avoid clicking on malicious links, and report potential security threats immediately. Another critical measure is the implementation of multi-factor authentication (MFA).

Passwords alone are no longer sufficient to prevent unauthorised access to business accounts. MFA provides an additional layer of security by requiring employees to verify their identities through one-time passcodes, biometric authentication, or security tokens. Microsoft reports that MFA can block 99.9 per cent of automated cyberattacks, underscoring its importance in securing remote work environments.

Encryption is another essential security practice that businesses must prioritise. Encrypting company devices and sensitive data ensures that, even if information is intercepted by cybercriminals, it remains unreadable and unusable. Organisations should adopt end-to-end encryption for emails, cloud storage solutions, and virtual private network (VPN) connections to protect data both at rest and in transit.

Addressing security risks in remote communication asin the widespread adoption of video conferencing and collaboration tools has introduced new security challenges. Throughout the pandemic, incidents of virtual meeting hacking, known as Zoombombing, exposed the weaknesses in unprotected video calls. As these platforms continue to serve as the backbone of remote collaboration, businesses must enforce strict security protocols to prevent unauthorised access to sensitive discussions.

Employees should only use company-approved communication tools with built-in encryption. Meeting links should not be shared on public forums, and access should be restricted to verified participants. Employers must establish policies that define when meetings should be recorded and how recordings should be securely stored to prevent unauthorised distribution of sensitive information.

While businesses play a crucial role in setting cybersecurity policies, employees can strengthen their cyber defenses. The security of a remote work environment is only as strong as the weakest link, and individual workers must take responsibility for safeguarding their digital workspace.

One of the most effective ways to enhance security is through strong password management. Weak and reused passwords are responsible for 80 per cent of hacking-related breaches.

Employees must create complex passwords that combine letters, numbers, and special characters, and they should never reuse passwords across multiple accounts. Password managers can assist in securely storing credentials and generating unique passwords for each service. Securing home networks is another vital step in reducing cyber risks.

Many remote workers continue to use the default passwords on their routers, leaving their Wi-Fi networks vulnerable to unauthorised access. Employees should change their router passwords, enable WPA3 encryption, and limit network access to trusted devices. Using a VPN when accessing company systems further protects against potential cyber intrusions.

Keeping software and devices up to date is equally important.

Cybercriminals frequently exploit unpatched vulnerabilities in outdated software to infiltrate systems. Employees must enable automatic updates on their operating systems, security software, and business applications to ensure they are protected against the latest threats.

There is a need for stronger data protection policy in addition to technical security measures in Nigeria, the Nigeria Data Protection Regulation (NDPR) sets out specific guidelines on handling personal and corporate data. Businesses must implement clear policies governing data collection, storage, and transfer to avoid regulatory violations and potential legal liabilities.

Companies working with third-party service providers must also ensure that these vendors adhere to the same security standards. Any organisation that stores or processes data outside Nigeria must comply with international data protection frameworks, including the General Data Protection Regulation (GDPR). Employees must be educated on their role in maintaining compliance and securing sensitive company information.

The digital transformation of the workplace is inevitable, and cybersecurity must be a core focus for businesses and employees alike. As a cybersecurity expert, I cannot stress enough the importance of continuous adaptation to evolving threats. Organisations that invest in robust security policies, advanced threat detection tools, and ongoing employee training will be better equipped to mitigate cyber risks.

At the same time, employees must develop a cybersecurity-first mindset. Simple actions such as securing home networks, recognising phishing attempts, and keeping software updated can make a significant difference in preventing cyber incidents. Cybersecurity is a shared responsibility, and by working together, businesses and individuals can build a more secure and resilient digital workplace.

As remote work continues to define the future of employment, those who take cybersecurity seriously will not only protect their operations but also gain a competitive edge in an increasingly interconnected world. The time to act is now.
