How to prevent a website from being attacked? Detailed explanation of all-round protection measures

in the current surge in Internet traffic, the website as the core carrier of enterprise customer acquisition and brand display, its security and stability are directly related to the normal operation of the business. But all kinds of network attack methods emerge one after another, from common SQL injection, DDoS attacks to hidden malicious code implantation, which may lead to website paralysis, data leakage, and immeasurable losses to enterprises. This article will dismantle practical strategies to prevent website attacks from basic protection, real-time monitoring, emergency response and other levels, and provide website managers with landing security solutions.

The basic protection configuration of the website being attacked?

basic configuration is the first line of defense against website attacks, and doing these details can greatly reduce the probability of being attacked and avoid security bugs caused by low-level mistakes.

1, timely update system and program version

most cases of website attacks, attackers use known vulnerabilities in systems or programs to launch intrusions. Whether it is the server operating system or the CMS program used to build the website, the official will regularly release security patches to fix vulnerabilities. Website managers need to develop the habit of regularly checking for updates, shutting down unnecessary system services, and reducing potential attack entrances.

2, strengthen account authority and password management

weak passwords, over-authorized accounts are common breakthroughs in website attacks. To set hierarchical permissions for operators in different positions, avoid ordinary employees having the highest authority in the server or website background; at the same time, require accounts to use complex passwords containing letters, numbers, special symbols, regular forced replacement, and prohibit multiple people from sharing the same account.

3, configure web application firewall rules

Web application firewall can filter HTTP/HTTPS requests in real time, blocking SQL injection, XSS cross-site scripting and other common attacks. Configure precise protection rules according to website business needs, such as limiting the frequency of single IP requests and filtering request parameters with malicious characters, blocking the risk of website attacks from the traffic level.

Real-time monitoring and early warning of website attacks?

static protection alone is not enough to deal with changeable attack methods, real-time monitoring allows managers to detect signs of website attacks in time and take measures before the attack has a serious impact.

1, build a website traffic monitoring system

real-time monitoring of website access data through professional traffic analysis tools, focusing on abnormal traffic fluctuations, such as a large number of requests from the same IP in a short period of time, sudden access peaks in non-business hours, etc., which may be precursors to website attacks. Once an abnormality is found, the suspicious IP can be banned immediately to avoid the expansion of the attack scale.

2, regularly scan the website security bugs

use professional vulnerability scanning tools to conduct comprehensive security inspections on the website every week or month to troubleshoot potential SQL injection vulnerabilities, file upload vulnerabilities, weak passwords and other issues. After the scan is completed, fix the discovered vulnerabilities in time, and keep the scan report, compare the scan results of different cycles, track the vulnerability repair, and prevent the website from being attacked and exploiting the unfixed vulnerabilities.

III. Website attack emergency response preparedness?

even if the protective measures are perfect, it is impossible to completely eliminate the possibility of the website being attacked. Preparing for emergencies in advance can quickly stop losses when an attack occurs and reduce business interruption time.

1, develop standardized emergency response processes

clear the disposal steps after the website is attacked, such as the first time to isolate the attacked server, backup the current website data, troubleshoot the source of attacks and vulnerabilities, and gradually restore website access after repairing vulnerabilities. At the same time, arrange a special person to be responsible for emergency docking to ensure smooth connection of all links and avoid secondary losses due to panic.

2, regularly backup website data and configuration

data backup is the last guarantee against website attacks, to use multi-copy backup strategy, such as website data backup to local servers, cloud storage services and offline storage devices at the same time, at least once a week for full backup, daily incremental backup. After the backup is completed, regularly verify the integrity of the backup data to ensure that the website is attacked and data loss can be quickly restored.

Fourth, the website is attacked by third-party security tools?

for small and medium-sized websites that lack professional security teams, third-party security tools can effectively improve protection capabilities, make up for their own technical shortcomings, and reduce the risk of website attacks.

1, choose cloud security protection service

cloud security service provider has a professional attack protection cluster, which can quickly resist high-traffic DDoS attacks and provide real-time vulnerability monitoring and repair suggestions. After connecting the website to the cloud protection platform, it can use the traffic cleaning capabilities of its global nodes to disperse the attack traffic and avoid the website being attacked resulting in server bandwidth exhaustion and inability to access normally.

2, use professional code audit tools

custom development of website code is prone to hidden security bugs, through professional code audit tools can automatically detect logic defects in the code, injection risks and other issues, help developers to fix potential hidden dangers in advance, reduce the possibility of website attacks from the code level.

To sum up, preventing website attacks is a long-term systematic work, which needs to be coordinated from multiple dimensions such as basic configuration, real-time monitoring, emergency preparedness, and the use of third-party tools. Website managers should establish a normalized security awareness, regularly sort out the protection process, and timely update the protection strategy.
