'Zero-day' security error protection procedure

Zero-day errors are becoming more common, but more dangerous, they are present in widely used software such as Microsoft Excel, Word or Internet Explorer.

"Zero-day" error is a term used to refer to dangerous security errors that can be exploited with code or programs and completely unpatched from the manufacturer.

Users will be the main victims when zero-day errors are published on hacker websites and exploited. However, we can also protect our system when there is a zero-day error before the manufacturer releases the official patch. The following are suggestions for system changes and upgrades to avoid being exploited when there is a 'zero-day' error:

1. Internet Explorer 6 and earlier are "bug-free" versions, including "zero-day" errors. Without any program or software without errors, however, Internet Explorer 6 is already suffering from many dangerous errors or because of a large number of users, it has become an attractive target for master attackers destination. Upgrading to Internet Explorer 7 is the right choice or using FireFox, Opera or Avant Browser are always open options for users.

2. Try to change the habit of using software that has been declared a "zero-day" error without a patch. Free software sometimes works just as well as commercial software. Foxit Softwares programs can display and handle well with PDF files or

OpenOffice will be a good solution for text editing (replacing Word), spreadsheets (instead of Excel) . You can easily find "benefactors" providing free software with Simple keywords like "free PDF reader" or "free editor" on search engines such as Yahoo, Google and find the software that best suits your purpose.

3. Activate the automatic update function for Windows and for any program that has the update feature. The patch updates are not necessarily against the latest "zero-day" errors, but it will prevent attackers from exploiting older bugs because there will be a lot of subjective users who don't care. the loading of patches.

For Windows, go to Automatic Updates in Control Panel and then change to " Download updates for me, but le me choose when to install them " (Download patches but let me decide when to install them).

For other software, it is not difficult to find the update function. For example, with Firefox browser, go to Tools - Options - Advanced and select the Update tab. Same as above, next select " Ask me what I want to do as the course standard of action when Firefox finds updates ". Or sometimes you have to manually search like Adobe Reader, you will find an update in the Help menu and then select the Preferences button.

4. Select antivirus or PC protection programs that analyze and respond to system protection against unknown errors. This feature is included with Panda Antivirus with TruPrevent, anti-virus and anti-virus technology as well as other unidentified security risks.

5. Ensure that the firewall is always in real-time mode on your system. The firewall will protect the system against spyware, computer worms, and system vulnerabilities to protect them. Windows XP has a built-in firewall at a relative level for the average user. To activate, go to Control Panel, open the Security Center and click on Windows Firewall. High-end systems can choose more powerful firewalls like BlackICE, ZoneAlarm.

6. Restricting user permissions will be a good way when the system has been exploited from a security error. DropMyRights is a small and completely free utility that provides the ability to set permissions for most programs.

7. Always keep up to date with the latest security flaws so that you can protect yourself or have appropriate solutions. Refer to the Zero-day Tracker of eEye Digital Security.
