Email Security Protects Your Privacy
4 Corner IT offers email security to keep your private messages private.
The Internet is an expansive network of computers, much of which is unprotected against malicious attacks. From the time it is composed to the time it is read, email travels along this unprotected Internet, perpetually exposed to electronic dangers.
Many users believe that email privacy is inherent and guaranteed, psychologically equating it with postal mail. While email is indeed conventionally secured by a password system, the one layer of protection is not secure, and generally insufficient to guarantee appreciable security.
Businesses are increasingly relying on electronic mail to correspond with clients and colleagues. As more sensitive information is transferred online, the need for email privacy becomes more pressing.
4 Corner IT Email Security guards against the following conditions
- Disclosure of Information: Most emails are currently transmitted in the clear (not encrypted). By means of some available tools, persons other than the designated recipients can read the email contents.
- Traffic analysis: It is believed that some countries are routinely monitoring email messages as part of their surveillance. This is not just for counter-terrorism reasons but also to facilitate combat against industrial espionage and to carry out political eavesdropping. However, it is not devoted to the national agencies since there is a thriving business in providing commercial and criminal elements with the information within emails.
- Modification of messages: email contents can be modified during transport or storage. Here, the man-in-the-middle attack does not necessarily require the control of gateway since an attacker that resides on the same Local Area Network (LAN), can use an Address Resolution Protocol (ARP) spoofing tool such as “ettercap” to intercept or modify all the email packets going to and from the mail server or gateway.
- Masquerade: It is possible to send a message in the name of another person or organization.
- Replay of previous messages: Previous messages may be resent to other recipients. This may lead to loss, confusion, or damage to the reputation of an individual or organization. It can cause some damage if email is used for certain applications such as funds transferring, registration, and reservation.
- Spoofing: False messages may be inserted into mail system of another user. It can be accomplished from within a LAN, or from an external environment using Trojan horses.
- Denial of Service: It can put a mail system out of order by overloading it with mail shots. It can be carried out using Trojan horses or viruses sent to users within the contents of emails. It is also possible to block the user accounts by repeatedly entering wrong passwords in the login.
