Website security refers to preventing websites from being attacked by foreign computer intruders website To do a series of defense work by hanging horses, tampering with web pages and other behaviors. Launching a new website is an exciting project, filled with many important steps and decisions. However, as the owner of a website, you should not only deal with the consequences of being hacked, but also be responsible for the content on its page and the mechanism people use to interact with it. If you plan to store user information (such as passwords or phone numbers), you must properly protect the data, or you may be fined for data leakage under some laws. To protect your website, you should take the following security measures.
1. Connect to the secure network
Avoid connecting to networks with unknown or uncertain security features, or to networks with poor security, such as unknown open wireless access points. This is especially important whenever you have to log in to the server or Web site for management, or access other secure resources. If you have to access a Web site or Web server when connecting to a network without security guarantee, you must use a security proxy, so that your connection to security resources will come from a network proxy with security guarantee.
2. Obtain SSL certificate
If you plan to transfer any sensitive user data on the Web server, you must use a Secure Sockets Layer (SSL) certificate. SSL is an encryption protocol that occurs at the browser level to ensure that all incoming and outgoing Web requests are shielded by outsiders. As the website owner, you are responsible for obtaining a valid SSL certificate from the authority and keeping it up to date. After using your domain name configuration, users will see the padlock symbol next to the URL in the browser, which is a common indicator of secure websites.
3. Accelerate with CDN
Although the global Internet has become faster and faster in recent years, there is still a delay when connecting websites in different regions. A popular solution is to use CDN acceleration. CDN providers maintain a set of servers in different regions to cache some parts of the content, so as to improve the loading speed of websites and achieve load balancing of large-scale traffic and reduce DDoS attacks Damage.
4. Use firewall to protect website security
For example, use the Internet Connection Firewall (ICF) provided with the operating system to check all data packets entering and leaving the firewall, and decide to intercept or release those data packets. A firewall can be a kind of hardware, firmware or software, for example, a special firewall device is a firewall in the form of hardware, a packet filter router is a router embedded with firewall firmware, and software such as proxy server is a firewall in the form of software.
5. Use redundancy to protect websites
Backup and server failover can help maintain maximum uptime. Although failover can greatly reduce server downtime, it is not the only value of redundancy. The backup server used in the failover plan can keep the server configuration up to date, so you don't have to rebuild your server from scratch in case of a disaster. Backup can ensure that client data will not be lost, and if you are worried that the data on the damaged system will fall into the hands of lawbreakers, you will not hesitate to delete such data. Of course, you must also ensure the security of failover and backup schemes, and check them regularly to ensure that they do not confuse you when you need them.
