If you're not careful, it may be possible for hackers to remotely connect to your computer without your knowledge and copy, edit or delete files. If you travel a lot and need to connect to unsafe wireless networks in hotels, airports, etc., you should make sure that you strengthen the security of your system so that you don't become a victim of a hacker.
In Windows XP, you can perform a couple of steps to ensure that you cannot access your computer remotely. Of course, you can't be 100% sure because of unknown security vulnerabilities in the operating system and programs, but better to do something rather than nothing.
Try to follow as many tips as possible below. If you are in a corporate environment, you probably don't have to worry about security as IT administrators are usually on top of that.
Disable remote connections to the computer
First, if you are not using Remote Desktop, go ahead and disable it. If you want to know more about Remote Desktop, read my post on how to install Remote Desktop on Windows XP. To disable the remote desktop, right click on Computer resources and select properties . Now click on the tab remote .
Go ahead and deselect Allow users to connect remotely to this computer . Now people cannot connect to the Windows XP machine using the remote desktop protocol. Obviously there are other protocols that a hacker can use, such as Telnet or FTP, so you need to make sure they are not enabled.
If the remote desktop is disabled on your computer and you cannot enable it normally, you can read my previous post on how to enable Remote Desktop via the registry.
Activate Windows Firewall to block incoming connections
You also want to make sure that Windows Firewall is enabled or that another third-party firewall program is installed. The Windows XP firewall will only block incoming connections on your computer, unlike Vista, which can filter both incoming and outgoing traffic.
can activate the firewall by going to Start, Control panel and clicking Windows Firewall . Make sure the radio button on is selected. Note that there is also an option called Don't allow exceptions .
This option is very useful when you are at the airport or in a place where you need to connect to an unsecured random wireless network. It will block all incoming connections, which means that you won't be able to use programs like Yahoo Messenger or GTalk, but you can browse the Internet. When you return to a secure secure connection, uncheck the box.
In addition, in the card Exceptions, make sure you don't have any unnecessary doors that are unlocked. You will have a list of programs and that's fine, but if you have many ports open, they can be used for attacks on your computer.
Disable Windows services for remote access
Finally, you can disable several services in Windows XP that will help reduce the "surface" of an attack on the PC. By default, Windows starts a couple of services that don't really need to be activated.
For example, there is a named service Remote registry activated by default, which allows you to access the registry through a remote computer. can disable these services by going on Start, Run and typing services.msc . Scroll down to the remote registry and right-click on it and select Stop .
Then right-click again and choose properties . In the combo box Startup type, change the value to disabled .
You also want to do this for the service Telnet as it allows users to connect to the computer via Telnet. This is all! These are some of the simple and common ways to protect your computer from remote access without your authorization! To enjoy!
