I hope to help you answer questions about how to prevent ADSL intrusion. Since the 21st century, the penetration of ADSL has developed rapidly as quickly as the arrows of the string. The penetration of ADSL into broadband has also become widespread in every household. At the same time, it has brought about many new problems, such as account theft. Just like the reason why Windows has more viruses than Linux, the reason is that the number of users is large, and the economic benefits of these attacks lead to illegal behaviors.
Many netizens have experienced ADSL account theft, especially when your bandwidth service is limited and limited, causing a lot of money to be lost for no reason, sometimes, even at the end of the month, the cost of surfing the internet is high. Many ADSL intrusion users often share broadband resources through routing. For most common users, as long as the route settings are complete and the machines in the LAN can access the Internet, everything is OK, in fact, this is far from the case.
With simple tools, hackers can easily break through your vro, intrude into your LAN, and steal your account and password, bringing immeasurable losses to you. So how should we protect our accounts from being easily stolen by others? We work out defense strategies from hacker intrusion techniques.
Generally, hackers use an IP scanning tool to scan an ADSL Network Segment, obtain the IP address from the result that can be connected, and then scan port 80, you can obtain a computer that has opened port 80. In the port 80 information, you can find out which program opened the port 80. Hackers can determine which is an ASDL vro based on experience and log on to the vro through the IE browser.
In this case, another problem occurs. to log on to the vro, you need to provide the user name and password. How do hackers know this. In fact, this is a very critical step. Many netizens directly connect to the network cable after purchasing the router, and do not care about the login user name and password. In this case, hackers can log on to the vro。 using the default username and password of the vro.
At this point, the hacker has full control over the vro, and then enters the ADSL intrusion account settings interface. by viewing the source code of this page, the hacker can easily obtain the username and password of the ADSL intrusion account. Therefore, the key to successful account theft is the login username and password of the router. After purchasing a vro, you must change the user name and password, at least the user name.
So it is safe to change the password? None. Hackers can also use the password cracking tool to crack your password. Therefore, you must set a complex password combination when changing the password, for example, you can add special characters such as English letters, numbers, commas, dots, and bars. As long as a hacker is not allowed to log on to your vro, he cannot easily obtain your ADSL intrusion account.
In addition, hackers can also use routers to intrude into your computer. If you control the router, your computer will be exposed to him. In this case, we also need to take appropriate security measures on the computer to prevent the entry of personal data into the hands of hackers.
Cancel folder hiding and sharing
By default, Windows 2000/XP enables hidden sharing of all partitions, select system tools, shared folders, and shared from the "control panel, administrative tools, and computer management" window ", you can see that each partition name on the hard disk is followed by a "$ ". However, if you type "\ computer name or IPC $", the system will ask the user name and password. Unfortunately, the password of the Administrator for most personal users is blank, intruders can easily see the content of the C drive, which poses a great risk to network security.
How can we eliminate default sharing? The method is simple. Open the Registry Editor and go to "HKEY_LOCAL_MACHINE/SYSTEM/CurrentControlSet/Sevices/Lanmanworkstation/parameters" to create a dual-byte value named "auto‑wks, set the value to "0" and restart the computer so that the sharing is canceled.
Disable unnecessary ports
Hackers often scan your computer ports during intrusion. If a port monitoring program is installed, a warning is prompted. In the event of such intrusion, the tool software can disable ports that are not in use, and other ports that are not commonly used can also be closed.
Change Administrator Account
Like a vro logon user, a hacker must have an administrator account to control your computer. Generally, users log on to the computer using the administrator. If you disable the administrator and create an administrator account with another name, hackers will not easily intrude into your computer, because hackers cannot obtain the Administrator account name through common means.
ADSL intrusion into the Guest account
A Guest account is a so-called Guest account. It can access computers but is restricted. Unfortunately, Guest also opens the door for hacker intrusion! There are many articles on the Internet that show you how to use the Guest user to obtain administrator permissions. Therefore, you must prevent system intrusion based on the Guest account.
It is the best way to disable or permanently delete a Guest account. However, if you have to use a Guest account, you need to take other measures to prevent it. First, set a strong password for Guest, and then set the access permission for the Guest account to the physical path in detail.
For example, if you want to prevent the Guest user from accessing the tool folder, right-click the folder and select the "Security" tab in the pop-up menu, you can see all users accessing this folder. Delete all users other than administrators. You can also set permissions for the corresponding users in the permissions, for example, you can only "list folder directories" and "read", which makes it much safer.
