A OL-25136-01 GLOSSARY Allowed Hosts Computers that are allowed to relay email through the Cisco IronPort appliance via a private listener. Allowed hosts are defined by their hostnames or IP addresses. Anti-Virus Sophos and McAfee Anti-Virus scanning engines provide cross-platform anti-virus protection, detection and disinfection. through virus detection engines which scans files for viruses, Trojan horses and worms. These programs come under the generic term of malware, meaning “malicious software.” The similarities between all types of malware allow anti-virus scanners to detect and remove not only viruses, but also all types of malicious software. B Blacklist A list of known bad senders. By default, senders in the Blacklist sender group of a public listener are rejected by the parameters set in the $BLOCKED mail flow policy. C Character Set (Double-byte) Double Byte Character Sets are foreign-language character sets requiring more than one byte of information to express each character. CIDR Notation Classless Inter-Domain Routing. A convenient shorthand for describing a range of IP addresses within their network contexts using an arbitrary number of bits. Using this notation, you note the network prefix part of an address by adding a forward slash (/) followed by the number of bits used for the network part. Thus a Class C network can be described in prefix notation as 192.168.0.1/24. A CIDR specification of 206.13.1.48/25 would include any address in which the first 25 bits of the address matched the first 25 bits of 206.13.1.48. Content Filters Content-based filters used to process messages during the Per-Recipient Scanning phase of the work queue in the email pipeline. Content filters are evoked after Message filters, and act on individual splintered messages. Cisco IronPort AsyncOS 7.6 for Email Configuration Guide GL-1
