Why is it so important for an e-mail to be digitally signed? Unencrypted messages can be hijacked in tr

26、ansit and read or altered. If the mail is not digitally signed, you cant be sure where it came from. 2. How many options are there for securing e-mail according to the passage? What are they? There are five options for securing e-mail according to the passage. They are: Secure/Multipurpose Internet

27、Mail Extensions (S/MIME); an e-mail security gateway; client-based methods by using your private key to sign messages; web-based secure mail services; building a directory of digital certificates.,3. What are the strengths and weaknesses of each option? Secure/Multipurpose Internet Mail Extensions (

28、S/MIME) Strength: it is the accepted standard and is built into leading e-mail clients such as Microsoft Outlook 98/2000 and Lotus Notes R5. Weakness: each vendor has implemented its own interpretation of S/MIME, which makes interoperability problematic. an e-mail security gateway Strength: every me

29、ssage going in or out passes through the gateway, allowing security policies to be enforced (where and when messages can be sent), virus checking to be performed, and messages to be signed and encrypted. Weakness: it doesnt provide user-based security.,client-based methods by using your private key

30、to sign messages Strength: it is a more granular level of security. Weakness: they need to be configured on each desktop, which includes issuing a digital certificate to each user (for encryption and digital signature), and ensuring that a proper security profile is configured within the e-mail clie

31、nt. web-based secure mail services Strength: you use a secure site on the Internet to compose a message and the web will keep the message within their environment at all times to ensure security. Weakness: this method does not work with existing enterprise e-mail systems.,Company Logo,building a dir

32、ectory of digital certificates Strength: internally, building the directory may not be a big deal because all certificates for a company can be published in a central Lightweight Directory Access Protocol server. Weakness: externally, this causes many problems. You will need to establish an agreemen

33、t with a recipients organization to ensure access to the right digital certificates. This process, however, creates more user training issues and adds complexity to e-mail communications. 4. Whats your own view on securing e-mail? Do you have other options for securing e-mail? If so, what are they?
