Policy Content Security can be best explained as a means of managing valuable content to meet security, legislative and other legal requirements. A frequently used definition is the analogy of the traveller at an international airport. The duties of the firewall can be likened to passport or immigration control, namely concerned with “Who” is authorized to enter or leave the organization. Content Security, by contrast, assumes the role of the customs official or X-Ray scanning machine, controlling “what” can be moved into, out of and around the organization.
Content Security is the sum of parts of a series of technologies which includes Email Scanning, Internet Access Control, Employee Internet Management, Malicious Mobile Code and also anti-virus tools (AV), URL filtering and firewalls – which, individually, all play a vital part in traditional security configurations.
Whereas Content Security solutions protect all points of entry to a corporate network – i.e. internal mail (Exchange, Notes), inbound and outbound mail (SMTP), Web-based email (HTTP) and other HTTP and FTP content threats – AV and firewalls fail to do so. Antivirus tools and firewalls certainly play a part in a security strategy, but they cannot protect you from all the content threats. Antivirus tools are essential for stopping viruses but they cannot prevent embedded or disguised threats in emails and attachments. Likewise, firewalls are great at providing access control – who can and can’t enter the network – but they do not protect against harmful content coming in and out.
Consider a financial report….
“When it is sent from the CFO to your auditors
rrWhen it is sent from someone in Sales Dept to your Competitors
When content moves it becomes a problem…
who is moving what to whom
So it’s just AV ?n
Anti Virus is just a part of the big picture
