in the context of digital operations, websites are the core windows for enterprises and individuals to display and trade externally, but they have also become the main attack targets of online black industry. Web attacks take various forms, from data theft to server paralysis. Once encountered, they will not only cause direct economic losses, but also seriously damage brand reputation. Many operators are often at a loss when they encounter web attacks for the first time and miss the best opportunity to deal with them. This article will share a complete set of web attack emergency response plans from identification, loss stop, repair to long-term protection, to help you quickly master response skills and protect website security.
timely identification of web page attacks is the first step in emergency protection, only to accurately determine the type of attack, in order to take targeted measures.
1, abnormal flow monitoring
web page attacks are often accompanied by abnormal traffic fluctuations, such as a large number of requests from the same IP in a short period of time, or the content of the request is mostly repeated invalid parameters. Operators can use the traffic statistics tool in the background of the website to pay attention to the PVUV value and the IP distribution of the request source in real time.
2, page abnormal performance recognition
web page attacks will also be directly reflected in the page display, such as the page suddenly appeared unfamiliar advertising pop-up windows, malicious jump links, or the original normal function module can not be loaded, and even display database error information. Some injection web page attacks will also tamper with page content, insert illegal text, these abnormal performance can be used as the basis for identification of web page attacks.
confirmed that the page attack, the first task is to quickly stop loss, to avoid the expansion of the attack range, reduce the degree of loss.
1, isolate abnormal access source
locate the IP segment or a single IP that launched the web attack through traffic analysis, you can immediately add blacklist rules in the server firewall or website security protection system to intercept all requests for the IP. For distributed web attacks, you can use the traffic cleaning function of CDN service providers to filter out malicious traffic and ensure that normal user access is not affected.
2, suspend high-risk function module
If the web page attack targets core functional modules such as login and payment, the external services of these modules can be temporarily suspended, such as closing the user registration entrance and suspending the online transaction function, and then gradually recovering after the attack situation is controlled. At the same time, backup the current website data in time to prevent data loss or tampering caused by web page attacks.
web page attack is completed, the website needs to be fully repaired to eliminate the security risks left by the attack and restore the normal operation of the website.
1, troubleshoot and patch vulnerabilities
web page attacks are often the use of security bugs existing in the website, such as SQL injection vulnerabilities, XSS cross-site scripting vulnerabilities. Operators can use professional website vulnerability scanning tools to comprehensively detect website code and server configuration, locate vulnerabilities and patch them in time, such as filtering user input content, upgrading website program versions, and preventing similar web page attacks from happening again.
2, restore the normal content of the website
If the web page attack tampered with the page content or database data, it can be restored through the normal data previously backed up. After the recovery is completed, check the page display and function operation one by one to ensure that all content is restored to normal. At the same time, the restored data is backed up twice to prevent subsequent new web page attacks from affecting data security.
response to a single web page attack is only an emergency measure, and the establishment of a long-term protection mechanism can fundamentally reduce the probability of web page attacks.
1, deployment of professional protective tools
can deploy a web application firewall at the front end of the website to monitor and intercept all kinds of web attacks in real time, such as SQL injection, XSS attacks, CC attacks, etc. At the same time, configure an intrusion detection system to alert the abnormal operation of the server, and timely find potential web attacks.
2, regular safety testing and training
regularly conduct vulnerability scanning and security evaluation on the website every month to find and patch new security bugs in a timely manner. At the same time, carry out Security Training for website operators to popularize the common types and responses of web attacks, improve the security awareness of the team, and avoid the risk of web attacks caused by human errors.
To sum up, the emergency protection of web attacks is a complete process from identification to stop loss, to repair and long-term protection. Rapid identification of web attacks is the premise of response, immediate stop loss can reduce losses, comprehensive repair and elimination of hidden dangers, and long-term protection can reduce the occurrence of web attacks from the root cause. Website operators need to master the skills of each link and establish a sound emergency response mechanism in order to deal with web attacks calmly and ensure the safe and stable operation of the website.
