As reported by HR Leader, a recent study from Getapp indicates that remote workers, or those working from home are more likely to be affected by a phone or email scam, due most likely to a lack of security measures in remote working environments. Employers have a responsibility to assist in developing security measures to mitigate this, including such firewalls as enforced password changing, two-factor authentication and providing anti-virus software.
