In this HowTo, I will explain how you can secure your network from virus and other malware, by installing ClamAV and integrating it with SafeSquid, to scan all in-coming content for virus, and block all infected content at the HTTP Gateway, even before it enters your network. Virus Security In SafeSquid SafeSquid has built-in connectivity to various daemon based anti virus software like ClamAV, Sophos, Avast, F-Prot, NOD32 and Kaspersky. It also has a universal ICAP (Internet Content Adaptation Protocol) client that can be used to connect to ICAP based security software like Dr.Web ICAP, Kaspersky Antivirus for Proxy Server, Trend Micro InterScan Web Security and Symantec Scan Engine. You can even use multiple anti virus software with SafeSquid to simultaneously scan in-coming content. This does not cause any significant latency, since SafeSquid has a multi-threaded architecture.

The WiKID Strong Authentication Server is a dual-source two-factor authentication system. PINs are encrypted on a software token and sent to the WiKID server. If the PIN is correct, the encryption valid and the account active, a one-time password is generated, encrypted and returned to the user's token where it is decrypted and presented for use with a network-based services. While there are a number of tutorials on how to combine WiKID's two-factor system a variety of systems (such as SSH, OpenVPN, Apache and SSL-VPNs), this is the first to address how to install the WiKID Server. We assume that you have already configured an RPM-based server. In general, it is best to have WiKID be the only service running on the server. This configuration will minimize potential security risks.
