Nowadays, with the progress of the Internet era to the rise of the Internet of things, people’s life, transportation and work are inseparable from online shopping, which is closely related to the goods are inseparable from various websites. Therefore, in a very fierce competition in various industries, it often happens that peers employ hackers to suppress their opponents and attack their websites, which leads to website paralysis. Today, I mainly share how to solve the problems of DDoS and vulnerability encountered by the website. Friends in need can refer to the following.
1. The first is to deploy the server of the website safely. If you want to develop rapidly, you must have stable foundation support. Then the infrastructure is the cornerstone. The password of the server needs to be changed frequently. One cannot be used for a long time to avoid leakage. At the same time, you need to set permissions on the site’s folders, including some important data, files, picture directories, cache directories, etc., which can be encrypted without script execution permissions. You need to set read-only permissions on the template’s folders, which does not include PHP operation permissions. The back-end address of the website should also be changed. Try not to use the default back-end address named admin, manage, Houtai, etc. the account password of the administrator of the website should be set to a complex point. Do not use the frequently used password and number to avoid being easily cracked.
2. Regularly upgrade the system of the website, patch and repair the loopholes, regularly conduct comprehensive security inspection on the website, and frequently inspect the script Trojan horse or the back door of the Trojan horse. Therefore, to choose a professional network operation and maintenance company, the professional security operation and maintenance personnel not only have professional technology, but also have rich experience. The repair of website vulnerabilities and the removal of Trojan back door can be well solved and avoided.
3. To back up the database and website code irregularly, now there are some virtual cloud servers used by enterprises. If the backup function is enabled, select the on state, and select a fixed period to back up the website server regularly, so that even if there is data loss or deletion due to attacks or system problems, you can use the backup. Timely restore to the latest status and data of the website. We also need to deploy SSL certificates for enterprise websites to prevent website data from being deleted, stolen, even tampered with and blocked by browsers. Yesterday, mozzard met a customer who told me that his website was blocked by Baidu. 360 and UC browsers all remind you to visit websites with unconfirmed information and visit carefully. At the same time, it also suggests that the hacked should use DDoS traffic attack to hide the real IP address of the website, filter out the malicious access requests by using the double protection, and then return the normal access to the source IP address, so as to avoid the DDoS and CC attacks on the website by the attacker.
Once a website is attacked, there will be various losses, such as sensitive data and documents of the enterprise, as well as the bank account of the user’s personal information involved, which are the lifeblood of the enterprise. However, if the website is well protected, there will be no data information leakage, and various losses of the enterprise in terms of property and reputation will be avoided.
