How has the corporate mailbox changed in the cloud computing era? First look at the situation abroad.

From a functional perspective, IMAP service is similar to the widely used POP3. It is a mail acquisition protocol, but the IMAP protocol is more advanced than the POP3 protocol. The main difference with the POP3 protocol is that users do not need to download all the mail You can directly operate the mail on the server through the client. The user can browse the letter header to decide whether to receive, delete and retrieve specific parts of the mail. It can also create or change folders or mailboxes on the server. In addition to supporting POP3 In addition to the protocol's offline operation mode, it also supports online operation and disconnected operation. It provides users with the ability to selectively receive mail from mail servers, server-based information processing functions, and shared mailbox functions. IMAP4's offline mode is different from POP3. It does not automatically delete the mails that have been removed from the mail server. Its online mode and disconnected mode also use the mail server as a "remote file server" to access, which is more flexible and convenient. For example, an email sent from iPhone4 will also appear in the sent emails of iPad and Lightning Mail. If you use POP3, there is no such function, all mails are downloaded to the local, all operations only affect local mails, cannot be synchronized to the mail server, and cannot be synchronized to other clients.

The system adopts modular design and good encapsulation, which makes the system powerfully expandable. The mail core system and mail front-end (Webmail) system can run on different hosts, and different modules of the software, such as the transceiver module, user authentication module, mail storage module, user access module, etc. can be run on different machines respectively. , Together to complete the functions of the entire email system. If necessary, each module can be split and run on different servers to achieve load sharing, so the system can be customized according to needs and user usage patterns. Through the multi-machine cluster technology, operators can handle the sending, management and storage of massive emails. According to load traffic management, operators can grasp the load status of the system and add servers according to business development needs. This system can support millions or even millions of users.

Viruses are rampant on the Internet,

In the past, you only needed antivirus software and basic anti-spam filters to ensure the security of corporate mailboxes. The effectiveness of these older generation mailbox security controls has plummeted. Attackers craft elaborate emails for specific target recipients, and they usually send such emails from hacked email accounts of recipients' friends or relatives. Emailed malware often exploits zero-day vulnerabilities, and no antimalware system can stop them. It can be seen that the email threat has escalated, and by its nature, this threat has become more dynamic and targeted. ^[1] Still relying on "bulky" internal e-mail systems, such as Microsoft Exchange and IBM Lotus Domino. Most companies need to deploy many emerging network security technologies to protect these systems. How to help businesses improve mailbox security. These technologies can often be added as add-ons to corporate email systems or as part of email security appliances, working closely with email servers.

Corporate Mailbox Reputation Management Services

One of the most effective ways to filter malicious content in emails is to subscribe to an email reputation management service. These services gather information (including data on senders, subjects, attachments, and many other characteristics) from the emails they receive from businesses to determine the likely intent of each sender. This information allows each business to take action based on its security needs and the relative reputation score of each sender to determine which emails the business allows to the recipient. The advantage of these services is that they are able to detect emails across many enterprises, which each company cannot achieve on its own.

Enterprise mailbox temporary isolation

One simple and very effective technique to stop the latest email attacks is to temporarily isolate suspicious emails. Many threats, especially those involving phishing, have extremely short lives. From phishing email production and delivery to the discovery of threats and the shutdown of supported malicious websites, it can only take a few hours. But anti-phishing technology cannot fully keep up with these rapidly emerging threats, so companies should temporarily delay mail when suspicious email content is detected. As with the email reputation management service, the configuration of temporary isolation should depend on the security needs of the enterprise, otherwise, this may lead to unintentional delays in normal emails and affect business operations. ^[1]

Corporate mailbox outbound mail filtering

Businesses should filter not only their inbound email content, but also outbound email. This can usually be achieved with existing technologies. For example, data loss prevention (DLP) products prevent the sending of emails containing sensitive personally identifiable messages (PII). The user may inadvertently send this email, or it may be maliciously sent by malware that infects the user's computer. Many businesses can also enforce content security policies on outbound email, such as preventing emails containing profanity or keywords ("confidential") with inappropriate content.

Business email email encryption

Policy-based email encryption mainly involves selecting emails for encryption based on some predefined criteria. For example, companies can formulate a policy that when certain senior leaders send emails that contain specific words or phrases in the subject, or have various attachments, they will be encrypted to protect their confidentiality. Enterprises can even choose to encrypt the contents of all internal emails, and there are technologies to encrypt emails sent outside the enterprise (such as business partners).
Ideally, the use of policy-based email encryption should be transparent to users and protect their emails without requiring them to choose whether to encrypt their communications for each message (some email encryption plugins do this). Given the spread of BYOD in enterprises, this is increasingly important because these devices often lack the security controls contained in mobile devices issued by enterprises. In environments where mobile device management (MDM) products are not deployed, policy-based email encryption is a very important security element. ^[2]
