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:

Antivirus software are computer programs that attempt to identify, neutralize or eliminate malicious software. The term "antivirus" is used because the earliest examples were designed exclusively to combat computer viruses; however most modern antivirus software is now designed to combat a wide range of threats including:

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. |

A firewall is a device or set of devices configured to permit, deny, encrypt, or proxy all computer traffic between different security domains based upon a set of rules and other criteria. A virtual private network (VPN) is a computer network in which some of the links between nodes are carried by open connections or virtual circuits in some larger network (e.g., the Internet) instead of by physical wires. |
|
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:
|

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. There are a number of types of security appliances. The most common of which is a network firewall that is an independent computer server appliance running specialized OS for this function. |

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. |

You are offering your IP address to the entire world at this very moment. When you are connected to the Internet, an IP address is used to identify your PC. If you don't protect yourself, this IP address can be used to access your computer from the outside world. |

Network behavior analysis (NBA) is a method of enhancing the security of a proprietary network by monitoring traffic and noting unusual actions or departures from normal operation. An NBA solution offers protection for a network in addition to that provided by traditional anti-threat applications such as firewalls, antivirus software and spyware-detection programs. |

Authentication is The process of verifying your access to the network by confirming your username and password and associating it with your computer. Authentication works by performing the following functions:
