In this paper, we'll discuss about email and their security issues. Email is that the most typical mode of communication these days. Email not only used for sending messages or text only but also to send audio, video and other files as attachment. We always relay on email's confidentiality and integrity for important data or communication. We'll discuss about the privacy issue, how the attacker attacks an email and the prevention of emails. This architecture will improve the security of accounts.
Our research suggests that only a proper knowledge of the prevention strategies will prove the best defence.

Email is a piece of information stored on a computer that is exchanged between two users over telecommunications. Email is a message which contain text, files, images, or attachments that sent through a network to an individual or group of individuals. E-mail travels on the web so they are exposed to the intruders.
Email is one of the technologies which a tool used by nearly every person with an internet connection. It allows you to no cost, send a letter of unlimited length and unlimited emails to one person or many people and they can reply straight away. Setting up your own email account will allow you easy to communicate with people which the place in everywhere.
In1971, the first e-mail was sent by Ray Tomlinson. Tomlinson sent the e-mail to himself as a test e-mail message which is containing the text something like "QWERTYUIOP".
However, despite sending the e-mail to himself, the e-mail message was still transmitted through ARPANET. By 1996, a lot of email correspondence was being sent than communication mail. the primary portion of all e-mail addresses, the half before the @ symbol, contains the alias, user, group, or department of a company. Next, Address consists two parts which is local part and domain name. The username should be unique that identifies the recipient. The domain name is the address and people can share the same domain name. The @ sign is used as a divider in the e-mail address; it is required for all SMTP e-mail addresses since the first message as sent by Ray Tomlinson.
Structure of email consists of two components. There are message header and message body. The message header which is control information including one or more recipient email address and subject header field. The message body which is email's content. For managing email which is keep your inbox uncluttered, delete what you don't need, automatically filter and process incoming emails.
The following table shows Email Usage Statistics in 2019 and The Most Widely Used Email Client in the World. Email is used to communicate in many settings. Modern email operates across internet or others computer network. Even though the use of email is decrease day by day between teenager but Gmail is the most popular email clients for google play, business, education and online banking. The reason why email usage is decrease because users like to message or text and share this information to the whole world via social apps which are very easily accessible. Employees share plethora of personal information on social apps thus putting their corporate infrastructure and data at a risk. However, the most popular client for sending emails is the Apple iPhone. Gmail have a 26% market share of all emails in the world, there is one service provider. It is one service provider that managed emailing service for the top spot.
Why to use email? We can differentiate between the advantages and disadvantages of emails. The advantage of email is easy to use and easy to reference when send and receive a message can be stored logically and reliably. We can save the time, Email is very fat, usually taking no more time than a few minutes to be received. The disadvantage of emails is some email cause upset or anger and information overload which is too many people send too much information. They often cite 'need to know' as the justification.
Simple password that commonly use by people. Some example of simple password would be like '123456', '111111', 'abcde', 'password'.. No matter how strong the network, email password still poses a threat. Implementing stronger password policies which is contains uppercase, lowercase letters, numbers and symbols.
If emails aren't encrypted, sending confidential data is like telling hackers "please, come steal our information." We don't want that to happen to any business, but it happens all too often. Have a clear policy about what should and shouldn't be sent over email and ensure any confidential data is encrypt.
Phishing is the act of tricking somebody to reveal your personal information or data. hackers create new user credentials or install malware such as backdoors into your system to steal sensitive data. The common practice is for attackers to send messages with a link to a malicious site and give a website to users that will try to convince them to install the malware. When user click on a link in an email to go to an account there will occur phishing scams looking for user data.
Emails with sensational titles like 'You've won a million dollars' or 'Poor people in Africa need your help' will attract user to click in. Email is the most common entry point for malware. Email attachments are one of the ways to spread malware. It's such unexpected email address, suspicious link within emails, malicious attachments and sensational subject lines. Zeus and CryptoLocker are types of malware that infect devices through email. These are some of the most dangerous malware that can empty your bank account.
When your smartphone or tablet is stolen, thieves will simply tap to view all emails. Devices are suggest to secured with a passcode or biometric security. We recommend securing devices and being able to remotely wipe them quickly.
Phishing is one of the fastest growing attack vectors. For hackers, it is a tried and tested method that has been successfully working for more than a decade. In fact, it has been more than two decades since the first reported phishing attack in 1995. Phishing occurs when a malicious party sends a fraudulent email disguised as being from an authorized, trusted source.
Spam also known as junk mail which is unsolicited email. We all have a "spam" folder in our email accounts where we receive unwanted emails or emails. Spam emails saw an increase within the last number of years due to the expansion of social media and e-commerce websites. Companies, for example, usually broadcast their "latest news" or announcements over email to large numbers of people who are a part of an opt-in list.
Adware is unwanted software which designed the advertisements up on your screen, most often on a web browser. Once adware hijacks your phone or laptop, it might carry out all sorts of unwanted tasks, risks and threat. Some versions of software automatically help your device install Adware.
The recently discovered type of email scam has been dubbed Vendor Email Compromise (VEC) and as its name suggests, the attackers prey on employees working at vendor companies The group, which Agari researchers call "Silent Starling," has been operating since at least 2018. It has targeted about 500 businesses throughout the world, compromising about 700 employees' email accounts along the way, the researchers estimate.
The Internet is used by everyone and anyone. The hackers can steal our precious data in many ways. Be careful what you post over email accounts, no matter how safe you think you are, the Internet will never be safe. Do not keep a copy of your email details on the Internet or on your system.
E-mail system normally consists of two sub systems which is the user agents and the message transfer agents. The user agents allow user to read and send e-mails. The message transfer agents transfer the messages from source to destination. he user agents provide a command based, menu-based, or graphical method for interacting with e-mail system. The message transfer agents are processes that run in background. Their job is moving the datagram e-mail through system.
There are four scenario used to exchange the email: First scenario is sender and the receiver of the email are on the same system. They are connected to shared system and need two user agent. When Alice need to send a message to Bob, Alice run the user agent program to prepare the message and store in Bob's mailbox.
Second scenario is the sender and the receiver use two different systems. The message needs to send over the internet. We need user agent and message transfer agent. The sender use user agent to send her message to the system. The recipients need user agent to retrieve message. Here need one client and one server
Third scenario is the sender connects to the system via point to point WAN and needs user agent to prepare the message. Then through a pair of message transfer agent, send the message through LAN or WAN.
Fourth scenario is the recipient connets to his email server by WAN or LAN. After message arrived, recipient need to retrieve it. we need two user agent, two pairs of message transfer agent which is client and server, and a pair of message access agent.
The proposed architecture provides the process of sending and receiving a message easier. The user agent programs that composes read, replies to and forward message. Its also can handles the mailboxes.
The proposed architecture which is easy for misunderstandings to occur with email, as there is only text and no tone of voice, or body language to provide context. Email can be sent anonymously and people who don't take the time to read what they write before clicking 'send'. It is also easy to make mistakes with email by clicking the wrong button. Email are so easy to send to multiple people, they can create information overload.
In the end, by e-mail communication is the most common way of exchanging information in almost every business and company. Don't share any password to a stranger. Be careful who use your device and where internet connection you connect. For prevention you should take precautions hence for this you can take advantage of the public available solution Having a robust, effective email security solution has been a necessity for most organizations today. It is the responsibility of every individual to protect themselves with sensitive personal identifying information.
