The security analyst should review the message in a secure environment first. This will help determine if the message is indeed spam or if it contains any malicious content, such as malware attachments or phishing links. Reviewing the message in a secure environment means using a sandbox or an isolated system that can prevent any potential harm to the analyst’s system or network. If the message is confirmed to be spam or malicious, then the analyst can take further actions, such as blocking the sender, deleting the email, or notifying the users3.
