Threats to Email Security and How to Prevent Them
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. An unencrypted email can be monitored and intercepted in many ways. 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. They call this phishing or fraudulent mails which ask people for important personal information like password or account name.
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 phishing emails can look like it is coming from a bank or an internet vendor asking for information. 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. You can be asked to log on to your account and other immediate actions that they demand. They will also let you enter passwords and account names into a web page created by the phisher himself. If you want to prevent phishing and forgery happening to your emails, then take note of these important things.
A service that controls and logs access to systems, resources, and applications that protects against unauthorized use is called access control. There is a need for account names and passwords in the network so that unauthorized persons cannot access your email messages on the network.
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. Unilateral authentication, on the other hand, requires only one party to verify his identity.
The confidentiality and integrity of the email means that it can be transmitted secure without being modified in transit. When data is in transit, it is protected from unauthorized modification through confidentiality and integrity.
