Chapter 18. Mitigation Technologies for E-mail-Based and Web-Based Threats

This chapter covers the following topics:

Mitigation technology for e-mail-based threats

Mitigation technology for web-based threats

Efficient e-mail-based and web-based security requires a robust solution that is expanded beyond the traditional perimeter, as new threats are emerging on a daily basis. The Cisco E-mail Security Appliances (ESA) and the Cisco Web Security Appliance (WSA) provide a great solution designed to protect corporate users against these threats. Cisco has added advanced malware protection (AMP) to the ESA and WSA to allow security administrators to detect and block malware and perform continuous analysis and retrospective alerting. Both the ESA and WSA use cloud-based security intelligence to allow protection before, during, and after an attack. This chapter covers these technologies and solutions in detail. You will learn mitigation technologies such as spam and antimalware filtering, data loss prevention (DLP), blacklisting, e-mail encryption, and web application filtering.
