Email security:
- Refers to the collective measures used to secure the access and content of an email account or service. It allows an individual or organization to protect the overall access to one or more email addresses/accounts. An email service provider implements email security to secure subscriber email accounts and data from hackers – at rest and in transit.
- Refers to services and solutions that focus on blocking and mitigating the effects of illegal emails – or spam – on email users. To achieve this objective, different types of anti-spam systems have been integrated with the email systems of many email and Internet service providers (ISP).
Modern anti-spam: Technology covers a broad spectrum of filters, scanners and other types of applications. Some anti-spam services work from a statistical method, while others use heuristics or predictive algorithms.
