What is Content Security?
Rapid growth in the use of the Internet has drastically changed how companies do business. Content Security is the fastest growing sector of Internet Security. According to IDC, a Massachusetts-based market research firm, content security revenues are expected to grow from $66 million in 1999 to almost $1 billion in 2004.

TThe need for content security is increasing as virtually every company today is connected to the Internet. These positive technological developments opened new avenues to potential dangers: lurking viruses, pornography, oversized files or banned types, spam and malicious mobile code. These new dangers can bring down networks, spur harassment lawsuits and downgrade productivity of both systems and people.

Until recently, Internet security was limited to more conventional security methods, such as firewalls. Firewalls are limited in that they verify Internet access only on the basis of IP addresses (e.g. 212.xxx.xxx.xxx).

Content is not verified in conventional Internet security methods.

Hackers hide their damaging content in emails in the form of viruses, worms and malicious mobile code. For example, the infamous “I Love You" virus caused enormous problems worldwide. Hackers gain access via the Trojan horse technique to mission critical company data. The damage a virus can cost a company can be devastating.It is estimated that last year alone viruses caused approximately US$ 11 billion worldwide in damage due to downtime, loss of employee productivity and data loss. This is why companies must tighten their security processes and implement content based security.

As Internet and email programs become more user friendly, an increasing number of users download damaging content. For example, malicious mobile code is more frequently downloaded to user’s PCs from more remote Internet pages, or viruses are spread through the company’s network. Viruses gain access to the address book and send out a copy of themselves to every recipient in the address book. To reduce the risk of viruses entering into the internal network, administrators use firewalls to filter out particular file types, such as *.vbs, Java applets or ActiveX controls.

A conventional firewall cannot distinguish between wanted and unwanted content.

A conventional firewall filters all file types with a particular extension. This traditional type of security also filters mission critical data. For example, identical file extensions used by viruses are also used for Internet banking, animated and interactive web presentations and Internet shopping. This type of limitation in Internet security leads to a reduction in a company’s direct Internet business needs.

Conventional firewalls and virus scanners alone provide no protection as they cannot automatically identify potentially damaging content. As a result, many viruses are allowed to pass though the firewall and enter the company’s network. There is a crucial need for a security solution that monitors the content of the entire internal and external network traffic. A content security solution requires the verification during real time of the entire content of certain websites, emails and transmissions, including all attachments.
