As a small business owner, it's crucial to prioritize security to protect revenue, time, and reputation from cyberattacks. Common types of attacks include phishing, RAT, keylogger, shoulder surfing, malware attack, Man-in-the-Middle attack, and others. To secure infrastructure, employees can take steps such as not leaving their computers unattended, using a virtual private network (VPN) when connecting to public Wi-Fi, using a privacy screen, clicking on unknown links with caution, keeping everything up-to-date, using full-disk encryption, creating regular backups, using strong passwords, and enabling two-factor authentication. By implementing these measures, small businesses can significantly reduce their risk of falling victim to cyberattacks and protect sensitive information.
