Advanced Spam & Virus Defense System
The Advanced Spam & Virus Defense System provides comprehensive spam-blocking for your organization. The algorithms and methods used by the Advanced Spam & Virus Defense System are the most comprehensive and most advanced in the industry. The Advanced Spam & Virus Defense System even includes Bayesian analysis which has been shown to be the most effective and most accurate method of blocking spam.
The methods and techniques used by the Advanced Spam & Virus Defense System are constantly updated (via hourly Updates), to keep up with changes that spammers and virus writers are constantly making.
The Advanced Spam & Virus Defense System uses a default
"best practice" configuration to obtain the best results globally.
These parameters are adjusted by our administrators on an as needed
basis to provide the highest level of global protection on the
Anti-Spam devices.
The Advanced Spam & Virus Defense System is a highly intelligent piece of hardware that handles all the processing and filtering. One simple change to the (MX) records and your email is instantly flowing through this device. Because Anti-Spam and Anti-Virus will no longer be processed on your server it will free resources, increase performance, and decrease threats on your server.

Key Benefits of The Advanced Spam & Virus Defense System
- Increased Security - Virus/Spam that never reach your server means it have a higher degree security.
- Lower Bandwidth Usage - Mail is processed and filtered before it reaches the server, reducing bandwidth usage.
- Central OPS Updates - Fully managed updates handled by FastServers.Net (daily).
- Ease of Use - Once your (MX) record is pointed to the device, everything else is processed and handled by the device without further configuration.
- Anti-Spam - The algorithms and methods used by the Anti-Spam & Anti-Virus service and the Barracuda Spam Firewall are the most comprehensive and most advanced in the industry at detecting and filtering spam resulting in the lowest rate of false positives.
- Anti-Virus - By utilizing dual layer virus blocking, decompression of archives and file type blocking, the anti-virus engine used by the Anti-Spam & Anti-Virus service and the Barracuda Spam Firewall provides complete virus protection.
- Anti-spoofing - This technology prevents the use of forged or "spoofed" sender addresses on unsolicited email. The anti-spoofing feature also allows larger organizations to specify a list of IP addresses that are allowed to have a "From" address that appears from inside the organization to support multiple sites and multiple email servers.
- Anti-phishing - The Anti-Spam & Anti-Virus service and the Barracuda Spam Firewall provides robust protection against phishing schemes which are often used to gather confidential information about an organization or its individual users.
- Anti-spyware (Attachments) - All attachments are scanned and any spyware executables are detected and eliminated immediately.
- Denial of Service Protection - Rate controls are utilized to stop denial of service attacks as well as dictionary based Spam attacks. These rate control systems are integrated and automatic in the Anti-Spam & Anti-Virus service and the Barracuda Spam Firewall
- Compatible with all Email Servers - The Anti-Spam & Anti-Virus service is independent of the type of mail server you are using.
- Dual Layer Virus Blocking The Barracuda Spam Firewall
uses two virus scanners to maximize protection. This provides two
layers for extra safety.
- Decompression of Archives The Barracuda Spam Firewall
unpacks and examines every individual file within 17 different types
of archives. It also uses techniques to examine password protected
archives.
File type Attachment
- Blocking The Barracuda Spam Firewall allows you to block
certain types of files. Many of the commonly blocked file types,
frequently contain viruses, such as VB script (.vbs files). These
blocking methods have become industry standard in order to provide
additional protection.

Some of the algorithms employed to block spam are listed below with a short description.
| Technique | Description |
| Blacklisting of websites & domains | Central OPS maintains an up to date list of the largest and most aggressive known spammers. This list is maintained by both Advanced Spam & Virus Defense System and other anti-spam groups. This list is automatically updated. |
| Keyword scanning of emails | Scanning methods include a scoring system such that emails are scored based on a number of criteria. If the score is above a threshold, then that email is flagged as spam. |
| Checksum technology | Central OPS monitors email traffic through the Internet and uses checksum technology to keep track of the number of times a particular message has appeared on the Internet. If a message has appeared very broadly, it would be categorized as known spam. Checksums of known spam messages are utilized by the Advanced Spam & Virus Defense System to block spam messages. |
| Message authenticity checking | Several algorithms are utilized to verify the authenticity of a message. Some of these are simple checks to verify that the "from address" is authentic. Some are more complex relating to SMTP protocol. |
| Blacklists and White lists | Domains, IPs, and email addresses can be blocked or white listed (allowed through). These lists may be maintained on a per user basis or on a corporate basis. |
| Rate controls | Rate controls are utilized to stop denial of service attacks as well as dictionary based spam attacks. These are integrated and automatic in the Advanced Spam & Virus Defense System. |
| Bayesian Algorithms | Bayesian filters are personalized to each user and adapt automatically to changes in spam. To determine the likelihood that an email is spam, these filters use Bayesian analysis to compare the words or phrases in the email in question to the frequency of the same words or phrases in the intended recipient's previous emails (both legitimate and spam). |
| Spam Fingerprint Checking | Fingerprinting techniques examine the characteristics, or fingerprint, of emails previously identified as spam and use this information to identify the same or similar email each time one is intercepted. These real time fingerprint checks are continuously updated by Central OPS and provide a method of identifying spam with nearly zero false positives. |
| Intention Analysis | Intention Analysis is used to look at the objective or goal of the email. If the objective of the email is to sell something, try and have you click on a commercial link, or get you to take a particular action that is indicative spam, the email will be categorized as spam |
| Dual Layer Virus Blocking | The Advanced Spam & Virus Defense System uses two virus scanners to maximize protection. This provides two layers for extra safety. |
| Decompression of Archives | The Advanced Spam & Virus Defense System unpacks and examines every individual file within 17 different types of archives. It also uses techniques to examine password protected archives. |
| File type attachment blocking | The Advanced Spam & Virus Defense System allows you to block certain types of files. Many of the commonly blocked file types, frequently contain viruses, such as VB script (.vbs files). These blocking methods have become industry standard in order to provide additional protection. |
