Media Gateway

A media gateway is a device that converts data from the format used on one network to the format used on another network. As an example, a VoIP gateway converts telephony traffic between traditional phone lines and an IP-based network. This allows users to make and receive phone calls using VoIP equipment and the gateway can translate the traffic and transmit the calls over a traditional phone line.

Proxy Servers

Many networks use proxy servers (or forward proxy servers) to forward requests for services (such as HTTP or HTTPS) from clients. They can improve performance by caching content and some proxy servers can restrict users’ access to inappropriate web sites by filtering content. A proxy server is located on the edge of the network bordering the Internet and the intranet, as shown in the figure.

Implementing Secure Network Using Devices

Administrators configure internal clients to use the proxy server for specific protocols. The proxy accepts their requests, retrieves the content from the Internet, and then returns the data to the client. Most proxy servers only act as a proxy for HTTP and HTTPS. However, proxy servers can also proxy other Internet protocols, such as FTP.

Caching Content for Performance

The proxy server increases the performance of Internet requests by caching each result received from the Internet. Any data that is in the proxy server’s cache doesn’t need to be retrieved from the Internet again to fulfill another client’s request. In this context, cache simply means “temporary storage.” Cache could be a dedicated area of RAM, or, in some situations, it could also be an area on a high-performance disk subsystem.

As an example, if Lisa retrieves a web page from GetCertifiedGetAhead.com, the proxy server would store the result in cache. If Homer later requests the same page, the proxy server retrieves the page from cache and sends it to Homer. This reduces the amount of Internet bandwidth used for web browsing because the page doesn’t need to be retrieved again.

Mail Gateways

A mail gateway is a server that examines all incoming and outgoing email and attempts to reduce risks associated with email. Many vendors sell appliances that perform all the desired services of a mail gateway. Administrators locate it between the email server and the Internet and configure it for their purposes. All mail goes to the gateway before it goes to the email server. Additionally, many vendors include a mail gateway within a UTM appliance. The mail gateway is just another security feature within the UTM appliance.

Spam is unsolicited email and attackers commonly use spam to launch attacks. For example, spam can include malware as an attachment or it might include a link to a malicious web site. A spam filter within a mail gateway filters out spam from incoming email. By filtering out spam, it helps block attacks.

Mail gateways often include data loss prevention (DLP) capabilities. They examine outgoing email looking for confidential or sensitive information and block them. As an example, imagine an organization is working on a secret project with a codeword of “DOH.” All documents associated with this project have the keyword within them. The mail gateway includes this keyword in its searches and when it detects the keyword within an email or an attachment, it blocks the email. Administrators have the choice of configuring the gateway to notify security personnel, the user who sent the email, or both when it blocks an email.

Many mail gateways also support encryption. They can encrypt all outgoing email to ensure confidentiality for the data-in-transit, or only encrypt certain data based on policies. For example, if an organization is working on a project with another organization, administrators can configure the gateway to encrypt all traffic sent to the other organization. The method of encryption varies from vendor to vendor. For example, some vendors use certificate-based encryption. Others use password-based encryption.
