What is Email Security?
Email security refers to the measures and technologies used to protect email communications from being accessed or manipulated by unauthorized parties. Email security involves safeguarding the confidentiality, integrity, and availability of email messages and attachments, as well as protecting against spam, phishing attacks, and other types of email-based threats. Email security measures can include the use of encryption, authentication, and malware detection technologies, as well as user education and awareness training. The goal of email security is to ensure that only authorized users can access and read email messages and that email communications are not altered or disrupted by unauthorized parties.

Common Attacks on Email
There are many different types of attacks that can be launched against email systems and communications. Some common examples of these attacks include:
- Phishing attacks: These attacks use fake emails or websites to trick users into giving away sensitive information, such as passwords or credit card numbers.
- Malware attacks: These attacks use email attachments or links to deliver malicious software – such as viruses or ransomware – to the victim’s computer.
- Spam: This refers to unwanted or unsolicited emails that are sent to a large number of recipients. While not inherently malicious, spam can be used to deliver malware or phishing attacks.
- Email spoofing: This is a type of attack in which the attacker impersonates a legitimate sender in order to trick the recipient into thinking the email is legitimate.
- Man-in-the-middle attacks: In these attacks, the attacker intercepts and manipulates email communications between two parties.
By understanding these types of attacks and how they work, individuals and organizations can take steps to protect themselves and prevent email-based attacks.
