Email Security : Requirement, Best Practices and Tools

What is Email Security?


Email security explains diverse procedures for storing delicate information in email communication and accounts protected against unauthorized path, loss or settlement. An Email is usually prepared to increase malware, spam and phishing attacks. Attackers use ambiguous reports to attract recipients. For sharing reports with delicate information, free attachments or click on hyperlinks. These install malware on the victim’s machine. It is also a common entry point for attackers scanning to gain a space in an enterprise network and important company data.


Email encryption involves encrypting, or changing, the content of email messages to preserve possibly sensitive knowledge from being read by anyone other than expected recipients. Additionally, it often includes authentication.


Email Security


An email was meant to be as open and accessible as feasible. It allows people in organizations to interact with each other and with people in other organizations. The difficulty is that email is not secure. This allows attackers to use email as a way to begin problems in an effort to profit. Whether through spam attacks, malware and phishing attacks, advanced targeted attacks, or business email compromise (BEC), attackers try to take benefit of the loss of security of email to carry out their actions. Since most organizations rely on email to do business, attackers use email in an effort to keep sensitive information.


Because email is an open setup, it can be viewed by anyone who can stop it. This became an effect as organizations began sending private or sensitive information through email. An attacker could easily read the contents of an email by preventing it. Over the years, organizations have been improving email security rules to make it harder for attackers. To get their hands on sensitive or private information.


Requirement of email security


Due to the reputation of email as an attack vector, it is dangerous that enterprises and individuals take actions to secure their email accounts upon common attacks as well as attempts at an unauthorized way to records or communicate.


Malware sent by email messages can be really harmful. Phishing emails sent to employees often include malware in attachments created to look like genuine documents or include hyperlinks that lead to websites that work malware. Opening an email attachment or clicking on a link in an email can be all that it takes for accounts or devices to become settled.

Phishing emails can also be used to cheat recipients into sharing delicate information, often by pretending as a genuine business or trusted contacts. Phishing attacks against businesses often target businesses that handle sensitive personal or financial information, such as accounts payable or human resources. In addition to representing known vendors or company executives, attackers will try to introduce a sense of importance in phishing emails to increase their probabilities of success. Phishing emails trained at stealing information typically will ask recipients to verify their login information, passwords, social security number, bank account numbers, and even credit card data. Some even connect to artificial websites that seem exactly like that of a reliable vendor or business partner to cheat victims into entering account or financial information.


Best practices

For Enterprise Email Security 


There are various ways to secure email accounts. For enterprises, it’s a two-pronged strategy comprising employee education and general security protocols. Best practices for email security include:


» Engage employees in open-ended security education around email security risks and how to evade falling victim to phishing attacks across the email.

» Require employees to adopt strong passwords and mandate password changes regularly.

» Utilize email encryption to preserve both email content and accessories.

» Perform security best practices for BYOD if your company allows employees to access corporate email on personal devices.

» Ensure that webmail applications are capable to secure logins and use encryption.

» Implement scanners and other tools to scan messages and block emails including malware or other malicious files before they reach your end-users.

» Implement a data protection resolution to recognize sensitive data and prevent it from being lost through email.

For End-User Email Security 


There are also some significant best practices that end-users should follow to assure secure email usage. Providing your employees with the know-how to avoid risky behaviors can make a real impression on your company’s capacity to reduce risks connected with email. Email security best practices for end-users/employees include:


» Never open attachments or click on links in email messages from anonymous senders.

» Change passwords regularly and manage best practices for creating strong passwords.

» Never give passwords to anyone, including co-workers.

» Try to send as few sensitive information as likely by email. And send sensitive information only to recipients who need it.

» Manage spam filters and anti-virus software.

»When working remotely or on a personal device, manage VPN software to reach corporate email.

» Avoid entering company emails from public wi-fi connections.


Therefore, by training employees on email security and achieving the specific measures to protect email, enterprises can relieve many of the risks. Risks that come with email methods and restrict sensitive data loss or malware viruses by email.



Tools of Email Security

A secure email gateway used either on-assumptions or in the cloud. It should give multi-layered protection from unwanted, malicious and BEC email; granular clarity; and business connection for organizations of all sizes. Also, these controls allow security teams to have faith. That they can secure users from email warnings and support email communications in the event of an interruption.

An email encryption solution reduces the risks connected with regulatory crimes, data loss, and corporate policy violations. This is while allowing necessary business communications. The solution should work for any organization that wants to protect sensitive data. While still making it readily accessible to associates, business partners, and users—on both desktops and mobile devices. An email encryption solution is particularly important for companies those who expect to follow agreement guidance. For instance, GDPR, HIPAA or SOX, or demand by security standards like PCI-DSS.
