Threats to Email Security and How to Prevent Them
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. Every time you send an email, you face a lot of threats including the interception of messages, modification or origin or content, forgery of content or origin by an outsider, forgery of origin or content by the recipient, or the denial of massage transmission.
Many times we send email that contain confidential or financial data to people within our company or sometimes even to people outside the company. If your email is not encrypted, then it 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. 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 email is monitored on a network, potential threats to recreate email from a company asking for sensitive information is allowed. 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 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 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 phisher also puts links in the email which is not the same link but he changes it to his own. Immediate actions are demanded in the emails including logging on to your accounts. Phishers are able to get your account name and passwords since you will be asked to register it in the web pages that they create. 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.
Authentication can prevent disguised attackes. The use of digital signatures is one integral mechanism for this service. Unilateral or mutual authentication are the two ways to authenticate identities In mutual authentication, both parties verify each other. 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. Data in transit is protected by confidentiality while unauthorized modification is ensured by integrity.
