Email server security threats come in all shapes and sizes, but can generally be classified into one of three categories:
- Denial of Service (DoS) attacks: In a DoS attack, the hacker floods the email server with so much traffic that it can no longer function properly. This can prevent legitimate users from accessing their email, or can even bring the server down altogether because of the high traffic.
- Malware: Hackers can embed malicious software into emails, which can then be transmitted to recipients’ computers when they open the email. This malware can damage or even destroy files, or steal sensitive information like passwords or credit card numbers.
- Spam: Unsolicited emails that are sent in bulk to large numbers of recipients are known as spam. While not necessarily a security threat in itself, spam can clog up email servers and cause legitimate messages to get lost in the email volume. Checkout the details about spam email here.
