Corporate managers understand that employees will conduct personal activities at work on the Internet, whether taking a few minutes to check personal stock portfolios or booking tickets during lunch hour. Some companies concerned with employee productivity, clogged bandwidth and sexual harassment suits potentially leading to hostile work environments have implemented Internet filtering tools to address these and similar issues.

Internet filtering, originally used for parental control over Internet surfing by their children, has reached the corporate world. Companies are blocking access to sites related to auctions, alcohol use, gambling and pornography. In many cases, Internet filtering applications are being used in companies that want to ensure that employees do not view pornographic or hate sites. Although this type of active viewing of pornography is not widespread throughout the enterprise, companies must act to ensure a good working environment is maintained.

At enterprises where "cyber slacking" is seen as a threat to network bandwidth, IT managers have also blocked sites related to sports and shopping. This has caused employees to view such actions as tantamount to creating a hostile work environment and led to many staff resignations.

An example of problems at the other end of the spectrum includes the arrest of Infoseek's executive vice-president, Patrick Naughton, for soliciting sex from a minor via the Web. Clearly, CIOs should work with human resources personnel and legal counsel to develop corporate policies and then evaluate and enforce them with Internet filtering software. The software should monitor or block or be a combination of both, whichever best fits the business situation.

Corporate policies should also include procedures for handling infractions of those policies within the organization. Both policies and infraction consequences should be clearly written and conveyed to all employees to avoid any future misunderstanding. However, companies should be sure the consequences fit the offense. For example, one should not be fired for checking a sports score. The appropriate filtering application should complement outlined policies. CIOs and their teams should carefully evaluate vendor offerings in order to determine which features are best suited for the enterprise.

In general, Internet filtering software combats the surfing issues either by using packet-sniffing technology to track employee surfing or works as an Internet gateway router (IGR) to triage Web traffic. Packet-sniffing technology inspects each request for access and ensures authorization or denies access. However, such software lacks the ability to recognize a re-sent packet, uses network resources before the packet is dropped and then consumes more resources as the packet is resent. In comparison, an Internet gateway router controls user access to and from the gateway but does not examine each request.

Many programs differentiate themselves by adding features such as on-demand Web activity reports and estimates of Internet surfing costs based on data such as employee salaries. Other features include daily updates of lists of sites to be blocked, filtering of both international and domestic sites, assignment of restrictions by department or workgroup and monitoring of bandwidth usage. Additionally, some programs can generate automatic e-mails to be sent to managers informing them of selected surfing activities that occur during off-hours.

CIOs should carefully evaluate software for features that combat specific problems from all sides. For example, blocking lists should include both domain names and Internet Protocol (IP) addresses. Also, each software vendor should provide a starter list and the ability to add additional listings, to speed creation of lists of banned sites. In addition, vendors of filtering and blocking software should offer frequent updates of blocking lists. The chart below lists example solutions for enterprise-class filtering and blocking.
