Security in E-mailing

Email Ulysse's Security Profile (User) - Send email and attachments using private key encryption and send them from the LAN to the LAN. E-mail looks easy from the user's point of view. You can select the address of the person you want to send an email, create a message and click Send. In fact, sending a message to the network cloud is somewhat similar to sending Little Red Riding Hood to a dark black forest. You do not know what will happen. Ulysses sends e-mails and images as e-mail attachments. Also, when sending e-mails, we send e-mail to other users using private key encryption.

It is the responsibility of the organization's IT department and e-mail administrator to protect the e-mail system. However, anyone responsible for the confidentiality, integrity, and availability of the information sent via e-mail will be aware of the threats that the e-mail system faces and the underlying technology that protects these systems It is necessary to understand. Users read, write, send, and save their e-mails using a mail client. The message is formatted and sent from the mail client to the mail server via the network infrastructure. A mail server is a computer that sends, forwards, and saves e-mails. Mail servers, mail clients, and the infrastructure to connect and support them - all components must be protected.

Mail server and mail client are two main components of e-mail system, but supporting network infrastructure is important for security operation. In many cases, a network infrastructure, including firewalls, routers, intrusion detection and prevention systems, provides the first layer of protection between untrusted networks and mail servers. The provisions of the US Reconstruction Reinvestment Act change the privacy and security rules of HIPAA, but it does not increase the need for healthcare providers to encrypt protected medical information. However, due to the two parts of ARRA, organizations may consider encrypting e-mails.

There are several ways to implement or access secure email. Encryption is an important part of email security. Furthermore, fortunately, I explained all the basic elements in the section above. From a practical point of view, safe e-mail means that when a sender sends an e-mail message, that message can only be read by the intended recipient. End - to - end implementation can only implement encryption; that is, the message must be encrypted before leaving the sender 's computer and can not be decrypted until it reaches the recipient' s system. However, in addition to privacy, we also need an email system that provides authentication, nonrepudiation, and message integrity. All features are provided by a combination of hash function, key encryption, and public key encryption. Then, a secure e - mail service or software usually provides two functions: message signature and message encryption.
