Justify your selections.

Answer 1

Some common risks using corporate e-mail system:-

• Malware
• Spam and phishing
• Social engineering
• Entities with malicious intent.
• Unintentional acts by authorized users.

Note-

• Microsoft Exchange 2007 reaches end-of life in April 11th. No further bugs or security exploits will be patched. If you’re still running Exchange 2007, then your entire server will soon be unsupported.

Privacy Safeguards:-

• Encrypt all outgoing messages:-

1. In Office 2010, on the File tab, click Options > Trust Center > Trust Center Settings.

2. On the E-mail Security tab, under Encrypted e-mail, select the Encrypt contents and attachments for outgoing messages check box.

3. To change additional settings, such as choosing a specific certificate to use, click Settings.

• Block phishing attacks:-

1. Use Block Sender frequently

   Select the spam email, right-click, choose Junk from the drop menu, and click Block Sender. OR Select Home > Junk > Block Sender. Outlook marks it and relocates it immediately.
