Many businesses have recently moved to a work-from-home policy to reduce the risk of Covid-19 (Coronavirus) infections among their workforce, but in doing so may have increased their exposure to cyber risk.

Outside of the office, workers may not have access to secure networks from which to work. For example, the Insurance Journal states that employees may be especially vulnerable to phishing emails, a technique used by hackers to install malware or ransomware on a computer, which typically have a harder time passing through the protections installed in office networks. Workers may also be tempted to work from public spaces such as coffee shops, where network security is notoriously weak.

Virtual Private Networks (VPNs) and two-factor authentication are two basic requirements that businesses should institute. For increased security, workers should make sure to only use private WiFi networks or personal hotspots from their phones. 

One consequence of the the coronavirus pandemic is to make visible the vulnerability of businesses to cyber attack when many employees are working from home -- a network is only as secure as its weakest link. Cyber insurance not only provides financial protection in case of an event, but the best brokers and insurers combine coverage with e-assessments of a business' current cyber defences, and provide recommendations for improving online security.
