Ways of Securing Email.

In many sectors of society, the preferred method of communication is through email. Using email is an easy and cost-efficient messaging solution but businesses must take care to protect the data they transmit both in the body of the message and the attachment it carries. Interception of messages, modification of origin or content, forgery of origin or content by an outsider, forget of content or origin by the recipient, or the denial of message transmission are just some of the threats that you can face every time you send an email over the internet or a network.

Sending emails with confidential or financial data can be done to people within your company or sent to people outside of your company. There are many ways by which any email that you send which is not encrypted can be monitored and intercepted. If this is the case, then your emails can easily be read, copied, and modified by unauthorized or malicious persons. These malicious users retrieve someone’s personal data and with this he can do a lot of bad things like emptying the victim’s financial accounts, run charges on existing credit cards, apply for loans, credit cards, services or benefits in the victims’ name, etc.

If people are able to gain access to your email in your network, then you will definitely allow malicious people to be able to copy emails that ask for sensitive information. Fraudulent mails or phishing as it is common called asks for personal information and other important data.

It is difficult to tell phishing emails from the real one because they look exactly alike to the last details like company logo, color scheme, and format. The company asking for information can be a bank or an internet business. Social engineering is the name given to this deceptive attempt at getting important information from people. The links in the email are changed to the one used by the phisher. Immediate actions are demanded in the emails including logging on to your accounts. Phishers create web pages where you will be asked to enter your account name and password. In order to prevent phishing and forgery happening to emails, there are important things that are needful.

A service that controls and logs access to systems, resources, and applications that protects against unauthorized use is called access control. To help prevent unauthorized persons accessing your email messages sent to someone else on a network, the network has to be secured using passwords or account names.

If you want to be protected from disguised attacks, authentication is important. The use of digital signatures is one integral mechanism for this service. You can authenticate identities with the use of unilateral authentication or mutual authentication. The two parties have to verify each other in mutual authentication. Only one party verifies its identity in unilateral authentication.

If data is transmitted without being modified in transit then there is confidentiality and integrity. Confidentiality protects data in transit and integrity protects unauthorized modifications.
