Ways of Securing Email.
In many sectors of society, the preferred method of communication is through email. Using email may be very easy and convenient for most of us, but we must take care to protect the data that we are transmitting, whether in its body or the attachments that you send. 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. An unencrypted email can be monitored and intercepted in many ways. The contents of the email is at risk of being read, copied or modified by unauthorized and potentially malicious users. Personal data retrieved by these malicious users can be used in bad ways like emptying your financial accounts, using your credit cards, apply for loans, and other malicious deeds.
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. This is known as phishing or fraudulent mails trying to persuade individuals to give up important personal information such as an account name or password.
It is easy to give your personal information in response to an phishing email since they look exactly like the original email including the logo, color scheme, and format. The company asking for information can be a bank or an internet business. The name for this deceptive attempt to gain information through fraudulent means is social engineering. 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. Below are some important things that can help prevent phishing and forgery in emails.
There has to be access control which is a services that controls and logs access to systems, resources, and applications and protects against unauthorized use. In order to prevent persons who are not authorized to access your emails, the network needs to be secured with passwords and account names.
To protect against disguised attacks there is a need to authenticate. One integral mechanism for the services is the use of digital signatures. Unilateral or mutual authentication are the two ways to authenticate identities The two parties have to verify each other in mutual authentication. In unilateral authentication only one party verifies the identity.
The confidentiality and integrity of the email means that it can be transmitted secure without being modified in transit. Confidentiality protects data in transit and integrity protects unauthorized modifications.
