How to protect against network keyloggers?

In the Internet age, information leakage has become a very common phenomenon in our lives. Among them, the network keylogger is a very efficient hacker attack tool. By recording the content entered by the user and stealing sensitive information such as user account password, it poses a threat to personal privacy and property. Therefore, how to effectively prevent network keyloggers has become an important challenge faced by us Internet users. This article will introduce you to several ways to avoid falling victim to online keyloggers.

1. Update the operating system and software regularly

Most network keyloggers exploit vulnerabilities in the operating system or software to carry out attacks. If the operating system and software are upgraded in time, loopholes can be patched and the harm of virus attacks can be avoided. Therefore, it is recommended to check for updates frequently and regularly to ensure that the operating system and software are always up to date.

2. Install anti-virus software and firewall

Network keyloggers often bypass the operating system's defense mechanism and pose a security threat to the system. At this time, it is very necessary to install anti-virus software and firewall. They can effectively identify and remove potential viruses, prevent attacks by network keyloggers, and strengthen computer security.

3. Don’t use public Wi-Fi networks

Public Wi-Fi networks are one of the important threats to network keylogger attacks. Operations involving sensitive personal information such as online banking and online shopping on public Wi-Fi networks can easily be monitored by hackers, resulting in the loss of account funds. It is recommended to use relatively secure networks such as home networks and mobile hotspots for online operations. It is best not to use Wi-Fi networks in public places such as Internet cafes and coffee shops.

4. Using Virtual Keyboard

Virtual keyboard is a software tool that converts user input into virtual keys instead of actual keyboard keys. Use a virtual keyboard to enter sensitive information such as usernames and passwords. Even if a network keylogger is recording, the real information content cannot be obtained. It can effectively protect account security and prevent sensitive personal information from being stolen by network keyloggers.

5. Adopt a correct password policy

Effective passwords are one of the important measures to avoid network keylogger attacks. Passwords should be complex and difficult to guess, and don't use simple passwords that include personal information and common words or numbers. And change passwords regularly, and do not use the same password multiple times on different websites. This can effectively avoid network keylogger attacks and improve account security.

In short, preventing network keyloggers requires us to take effective preventive measures from multiple aspects to protect our accounts and personal privacy. It should be noted that cyber threats are constantly changing and evolving. Only by remaining vigilant and paying attention can we better prevent and avoid the threat of cyber attacks.
