SNAPS: Embedded Network Security Appliance

Abstract

The bandwidth management is implemented for the purpose of availability of resource. So that fare sharing of available bandwidth between employees. The Hierarchical Token Bucket(HTB) concept is used to control the traffic between different classes. The secure socket layer VPN is implemented to provide secure access of organizations network from outside the organization. The traffic between the Web browser and the SSL VPN device is encrypted with the SSL protocol. Despite the popularity of SSL VPNs, here not intended to replace Internet Protocol Security (IPsec) VPNs. The two VPN technologies are complementary and address separate network architectures and business needs. The growing problem of spam mails has generated a need for reliable Antispam filters. Antispam(Spam Filtering) can be applied at the client level or the server level. Several options are available at the client level for spam filtering. However, such lists are used by service providers and network administrators to block an email before it is sent. The unintended consequence of maintaining these blacklists is that sometimes, innocent senders are inadvertently blocked from sending legitimate emails. Identifying and removal of spam from the email delivery systems allows end users to regain a useful means of communication.
