Identify open ports with netstat
Network security is a critical issue for businesses because of the potential for data theft, denial-of-service (DoS) attacks, and other threats. Knowing the exposure level for a given computer will help you better protect your machines.
The fewer ports open and listening on a computer, the less exposure there is to attack and potential compromise of the system. You can use the netstat program that comes with Windows to identify which ports are open on a system and identify current connections.
To identify ports, open a command console and type the following command:
To view an IP address for local and remote addresses rather than host names, add the -n switch:
If you only want to view active connections and not listening ports, use the netstat command without any switches.

Configure Content Advisor ratings for your Web site
If you've ever browsed through the settings for Internet Explorer, you might have run across Content Advisor, a feature in IE that lets you block site content by various rating levels. By default, IE uses the ratings defined by the Recreational Software Advisory Council (RSAC), which folded into the Internet Content Rating Association (ICRA) in 1999.
While RSAC no longer exists, IE's Content Advisor feature does, and many people use it as one method for blocking objectionable content. To accommodate site visitors who use Content Advisor, you can configure your Web site with the appropriate ratings.
To configure content ratings for IIS, follow these steps:
- Open the IIS console from the Administrative Tools folder, and open the properties for the site.
- On the HTTP Headers tab, click Edit Ratings to open the Content Ratings dialog box.
- On the Ratings tab, select the Enable Ratings option for this resource.
- In the Category list, click a category, and use the Rating slide-bar to choose a value based on the content of your site. Repeat the process for each category.
- Enter your e-mail address in the provided field, set an expiration date for the content ratings, and click OK.
