Outbound Email Security Threat
Prevent Unintentional Information Leakage Due to Insider Mistakes
What is Unintentional Information Leakage?
Unintentional information leakage refers to situations where information is unintentionally exposed without the sender’s intent. This can occur due to mistakes or technical flaws and is typically observed in the following scenarios:
- Internal mistakes: Users may inadvertently send emails containing sensitive information to the wrong recipients while composing or sending emails. For example, a user might send sensitive corporate information to an email address belonging to a different company.
- External attacks: Attackers may execute attacks on email servers or clients to intentionally exfiltrate information. This typically involves exploiting security vulnerabilities.
- External factors: When emails are sent to external organizations or third parties, the information can be exposed to them.
Pathways of Unintentional Information Breach
Careless Composition
When an employee or user composes an email, they may unintentionally include sensitive information or attach files containing sensitive data. Carelessness in handling sensitive information is one of the major causes of such incidents.
Incorrect Recipient Selection
Sometimes, individuals may mistakenly send emails to the wrong recipients or groups, even if they did not intend to disclose the information. For instance, sending an email containing confidential information to an external email address falls into this category.
Accidental Transmission
Information leaks often result from accidents. Mistakes made while composing emails or handling attachments can lead to sensitive information being sent via email. Accidentally disclosing information to someone else may also occur.
Repetitive Errors
Information disclosure incidents can be recurrent, stemming from repeated mistakes or carelessness by employees. If similar errors are made repeatedly, the likelihood of such leakage incidents increases.
