A listener defines an e-mail processing service that is configured on an interface in the Cisco ESA. Listeners apply to e-mail entering the appliance from either the Internet or from internal systems.
Figure illustrates the concept of Cisco ESA listeners. The listener properties must also indicate whether it is a public or a private listener. An administrator can specify which remote hosts can connect to the listener.
Log in to the Cisco ESA. The default username is admin, and the default pass- word is ironport. Step 2. Are you sure you wish to continue? Management PrivateNet PublicNet Hostnames such as "example.
Partial hostnames such as ". Usernames such as "postmaster " are allowed. Full email addresses such as "joe example. Separate multiple entries with commas. Rate limiting defines the maximum number of recipients per hour you are willing to receive from a remote domain. Defaults have been set for a Public listener. Defaults have been set for a Private listener. System setup is complete. For advanced configuration, please refer to the User Guide.
The domain name of securemeinc. To verify the configuration, you can use the mailconfig command to send a test e-mail con- taining the system configuration data that was entered in the System Setup Wizard, as shown in Example Example Verifying the Configuration with the mailconfig Command mail3. Separate multiple addresses with commas. Nowadays, you can download malware through compromised legitimate websites, including social media sites, advertise- ments in news and corporate sites, gaming sites, and many more.
Cisco has developed several tools and mechanisms to help their customers combat these threats. Both solutions enable malware detection and blocking, continuous monitoring, and retrospective alerting.
Cisco CWS Cisco CWS is a cloud-based security service from Cisco that provides worldwide threat intelligence, advanced threat defense capabilities, and roaming user protection. In addition, the scanning is offloaded from the hardware appliances to the cloud, reducing the impact to hardware utilization and reducing network latency. Figure illustrates how the transparent proxy functionality through a connector works.
The following steps explain how Cisco CWS protects the corporate users at the branch office: 1. An internal user makes an HTTP request to an external website securemeinc.
It notices that securemeinc. Cisco CWS blocks the request to the malicious site. This threat intel- ligence helps security professionals to stop threats before they enter the corporate network, while also enabling file reputation and file sandboxing to identify threats during an attack. Retrospective attack analysis allows security administrators to investigate and provide pro- tection after an attack when advanced malware might have evaded other layers of defense.
WCCP is a protocol originally developed by Cisco, but several other vendors have integrated it in their products to allow clustering and transparent proxy deployments on networks using Cisco infrastructure devices routers, switches, firewalls, and so on.
Figure illustrates a Cisco WSA deployed as an explicit proxy. An internal user makes an HTTP request to an external website. The client browser is configured to send the request to the Cisco WSA. The Cisco WSA connects to the website on behalf of the internal user. Figure shows a Cisco WSA deployed as a transparent proxy. The web traffic is sent to the Internet web server. Figure demonstrates how the WCCS registration works.
WCCP can be used in large-scale environments. Figure shows a cluster of Cisco WSAs, where internal Layer 3 switches redirect web traffic to the cluster. The Cisco AsyncOS supports numerous features that will help mitigate web-based threats.
It dynamically adds IP addresses of known malware domains to a database of sites to block. It enables an administrator to inspect web content by title, metadata, and size and to even prevent users from storing files to cloud services, such as Dropbox, Google Drive, and others. This file reputation threat intelligence is updated every 3 to 5 minutes.
For example, an administra- tor can allow users to use social media sites like Facebook but block micro-applications such as Facebook games. Cisco SMA has consis- 18 tent enforcement of policy, and enhances threat protection. Table lists these key topics.
