Close the registry is not an effective strategy for worm prevention. Security measures to prevent worm viruses: 1. Turn on personal firewall; 2. Check the accounts used by the machine, delete unnecessary accounts, and use complex passwords for necessary accounts; 3. Update security patches to prevent vulnerability-based attacks ; 4. Regularly check whether there are suspicious items in services, processes, and registries.
The spread process of worm virus is as follows:
Step one: Scan. The scanning process is to use a scanner to scan the host and detect the host's operating system type, version, host name, user name, open ports, open server software version, etc.
Step 2: Attack. The attack process is generally divided into two types. One is an attack that exploits vulnerabilities. If the operating system information or information about certain software returned by the scan is a vulnerable version, you can directly use the attack code for the vulnerability to obtain the corresponding permissions. Another type of attack is based on file sharing and weak keys. This attack requires trying to guess the user's password based on the collected information. Generally, worms have mechanisms such as testing empty passwords, simple passwords, and whether the password is the same as a known password. After guessing the correct password, you will have control over the remote host.
Step 3: Copy. Copying is actually a file transfer process, which uses file transfer protocols and ports for network transmission.
In order to prevent your computer from being attacked by LAN worms and infected with such viruses, it is recommended that users take the following basic security measures:
1. Turn on the personal firewall: According to Application conditions and for certain types of viruses, if you set some protection rules for protocols, ports, programs, intrusion detection, etc., the protection effect will be better;
2. Try to close unnecessary file sharing. In addition to shared files set by users, Windows operating systems generally have default shares such as C$, D$, ADMIN$, IPC$, etc. If these share attributes are removed, virus files cannot be copied locally;
3. Enforce password policies. Check the accounts used by this machine and delete unnecessary accounts. Use complex passwords for necessary accounts;
4. Apply all security patches to the operating system in a timely manner to prevent vulnerability-based attacks;
5. Regularly check services, processes, and registry entries If there are any suspicious items, promptly close or delete unnecessary services or startup items.
