Things you can do to safeguard your computer

• STAY ALERT!
  Sounds simple? But do you really know if you have the latest patch for your browser, the software you use everyday or even the operating system that you run all your programs on?
  Don't expect to hear about security issues and other software bugs in the traditional media such as the TV and news papers. Even if you subscribe to a technical journal, you may not get the news in time.
  • Use email notification services : Subscribe to email notification services related to the software you use. Don't forget to include your operating system, web browser and any other software that will connect to the Internet in this list. Almost all of these notification services are free and subscription information is usually found on the software publisher's web site or the software registration card.
  • Periodically check related web sites : If an email notification service is not available, add a task to your calendar to check your software publishers' web sites at least every month, if not every week. You may have to search their news archives to find any security bulletins.
  • Search newsgroups : Some software publishers may not provide timely information about their software glitches openly. In such instances, newsgroups dedicated to open discussions may help you to find related messages posted by other users. Be aware that the quality and the credibility of information gathered from newsgroups maybe lower than information retrieved using above two methods. Searching, rather than browsing messages one by one, is recommended when it comes to newsgroup postings. For example, search for:
    "product name" AND bug OR fix
• TAKE ACTION
  Once you become aware of a bug or a security issue, carefully read the documentation for it and take the recommended action.
  For example, if applying a software patch is recommended by the software publisher, do so as soon as possible. Don't delay taking action until the end of the month. Some software patches must be applied in a particular order. Applying fixes as they become available could make it easier to keep this order.
• KEEP DEFECTIVE SOFTWARE OUT OF REACH
  After applying patches to your current software installation, be sure to remove defective software from circulation and to document the actions you took for future reference.
  For example, if you receive a replacement CD or a floppy with a fix, remove obsolete disks from the circulation to avoid future confusions.
  If the fix was provided in a form of a patch (if you still need the original installation disks in case you have to reinstall the software), be sure to make a note of the patches you applied for future reference. You may want to keep a separate notepad for this purpose or simply label or mark the disks as a reminder to yourself.
