Case: Network security threat risk analysis
Network security threat risk analysis refers to the process of identifying network threats and determining prevention strategies through comprehensive and systematic detection and analysis of the network. Among them, hacker attacks and phishing attacks are the two main forms of network threats, which are analyzed separately below.

1. Analysis of hacker attacks
Hacker attacks generally refer to hackers illegally invading other people's computers or network systems through various means, obtaining confidential information, causing damage, and controlling systems. Due to its strong concealment, hacker attacks bring huge losses to the attacked.
There are many ways of hacking, the more common ones are malware attacks and phishing attacks.

1.1 Malware attack
Malware refers to some malicious programs and software, which can invade the user's computer through various methods and perform malicious actions, such as stealing personal information, encrypting data, and locking the computer. The means of dissemination of malicious software include email attachments, downloading software, and program loopholes.
In order to prevent malware attacks, users should ensure the security of their computer systems and avoid downloading and opening software and files from unknown sources. In addition, you can also install security software such as anti-virus software or firewall, and regularly repair and upgrade the system.

1.2 Phishing attacks
Phishing attacks refer to hackers forging a legal website or sending phishing emails and text messages on the Internet to lure users to click links or enter personal information such as account numbers and passwords, thereby stealing users' personal and financial information. Phishing attack is one of the more rampant means of network attack.
For phishing attacks, users can improve their security awareness, be wary of information from unfamiliar or unreliable mailboxes, text messages, web pages, etc., and check whether the URL of the website is correct to prevent phishing websites from being stolen.

2. Analysis of phishing attack
Phishing attack is a kind of fraudulent email, webpage or link to lure the victim to enter sensitive information, such as user name, password, credit card number and bank account, etc., and then achieve the purpose of illegally obtaining user information. Due to its concealment, phishing attacks can easily make users fall into the trap, causing immeasurable economic losses and privacy leaks.
There are various ways of phishing attacks, and the more common ones include forged emails, website text messages, and phishing software. In order to avoid phishing attacks, users should be vigilant, carefully check whether emails and websites are legitimate, do not easily download software installed on unfamiliar devices, and update network security knowledge and skills at any time.

Network security risks are increasing day by day, and we must pay close attention to them to effectively avoid the threat of illegal activities. Here, Zhian Network reminds everyone: Network security requires us to maintain it together, take action, start from ourselves, strengthen the learning and popularization of network security knowledge, enhance skills, protect our precious personal and corporate information assets, and strive to build network security community.
