To prevent e-mail spam, both end users and administrators of e-mail systems use various anti-spam techniques. Some of these techniques have been embedded in products, services and software to ease the burden on users and administrators. No one technique is a complete solution to the spam problem, and each has trade-offs between incorrectly rejecting legitimate e-mail vs. not rejecting all spam, and the associated costs in time and effort.

Anti-spam techniques can be broken into four broad categories:

• Those that require actions by individuals
• Those that can be automated by the email administrator
• Those that can be automated by e-mail senders
• Those employed by researchers and law enforcement officials

E-mail archiving is a systematic approach to saving and protecting the data contained in e-mail messages so it can be accessed quickly at a later date. In the past, companies often relied on end-users to maintain their own individual e-mail archives. The IT department would back up e-mail, but not in a manner that made messages searchable. If a specific e-mail needed to be traced, it often took weeks to find it.

Email filtering is the processing of e-mail to organize it according to specified criteria. Most often this refers to the automatic processing of incoming messages, but the term also applies to the intervention of human intelligence in addition to anti-spam techniques, and to outgoing emails as well as those being received.

Email filtering software inputs email. For its output, it might pass the message through unchanged for delivery to the user's mailbox, redirect the message for delivery elsewhere, or even throw the message away. Some mail filters are able to edit messages during processing.

Internet security is the prevention of unauthorized access and/or damage to computer systems via internet access. Most security measures involve data encryption and passwords. Data encryption is the translation of data into a form that is unintelligible without a deciphering mechanism. A password is a secret word or phrase that gives a user access to a particular program or system.

Internet security professionals should be fluent in the four major aspects:

• Penetration testing
• Intrusion Detection
• Incidence Response
• Legal / Audit Compliance

Security appliances protect computer networks from unwanted data traffic, intruders, e-mail spam, enforce policies, and may also be used to create and manage VPNs.

Content filtering is the technique whereby content is blocked or allowed based on analysis of its content, rather than its source or other criteria. It is most widely used on the internet to filter email and web access.

Content filtering is the most commonly used group of methods to filter spam. Content filters act either on the content, the information contained in the mail body, or on the mail headers (like "Subject:") to either classify, accept or reject a message.

Content filtering is commonly used by organisations such as offices and schools to prevent computer users from viewing inappropriate web sites or content. Filtering rules are typically set by a central IT department and may be implemented via software on individual computers or at a central point on the network such as the proxy server or internet router. Depending on the sophistication of the system used, it may be possible for different computer users to have different levels of internet access.

Software as a Service (SaaS) is a model of software deployment whereby a provider licenses an application to customers for use as a service on demand. SaaS software vendors may host the application on their own web servers or download the application to the consumer device, disabling it after use or after the on-demand contract expires. The on-demand function may be handled internally to share licenses within a firm or by a third-party application service provider (ASP) sharing licenses between firms. ASL Security offer SaaS Soltions by Websense and Webroot.
