Common ways website servers are attacked and solutions

[monira#$1244]

The server security is not set up properly, and the attacker enters directly by attacking the server, such as opening extra server ports, attacking the database and directly controlling the system (solution: open the firewall, close extra ports, and only open necessary ports. If you must open them, close them after the operation is completed)

Attack through website program vulnerabilities, such as some mainstream CMS systems (Wordprss) not being upgraded, third-party plug-in vulnerabilities; injection vulnerabilities; website backend editor or website front-end upload file permissions not being set properly, resulting in the upload of the corresponding Trojan, and then the execution of the Trojan causes the entire system to be contaminated. (Solution: Commonly used CMS should be regularly upgraded to the latest version, plug-ins should be used from the official website, and third parties should not be abused; upgrade the version of the website editor and set security; set the server upload directory permissions to non-executable, so that even if a Trojan is uploaded, it cannot be run; install anti-virus scanning software, and the uploaded Trojan will be detected and removed)

DNS hijacking means that when you visit your website, someone else's illegal ads will be displayed or you will be redirected to other illegal websites (solution: the website needs to deploy and install an SSL certificate)

After the server was attacked, the disk was encrypted and the ransom was canada b2b leads demanded in Bitcoin (handling method: there is no absolutely safe system. Before the system goes online, you should consider regular backup of the website or data. In addition to local backup, for example, copying the C drive to the D drive every Monday and Friday, you must regularly back up the data to the local or other servers; Internet service providers generally also provide cloud server mirroring services, which is to regularly clone the server's disk image. Of course, there will be some fees, but compared with data loss, it is a small matter; in this way, after the server or website is attacked, it can be restored as soon as possible)

The path of the backend management website is relatively common, the username and password are relatively simple, and there is no verification code set, which makes it easy for someone to attack the database to exhaust the password (solution: modify the backend address so that only you know it; the password should be complex, and the username should not be universal. You need to enter a verification code when logging in)
How to choose a website operating environment to reduce the probability of attacks
According to the network environment,

Virtual host : The virtual hosts of domestic first-line brands (Alibaba Cloud, Tencent Cloud, Huawei Cloud) are relatively safe, because they are on servers with better security settings, so you only need to pay attention to the security of the website program. Don’t consider the virtual host services of other small companies for the time being. If there is no other way, you must choose a dedicated IP address, because many companies will put many other company websites on the same server. For example, if there are illegal websites, the search engine will have a negative impact on the brand and reputation of your website; if the server is unstable, it will affect the search engine optimization and keyword website rankings. In addition, if multiple sites can be stored on the same server, other sites have security vulnerabilities and will attack the entire server, which will cause your website to be implanted with malicious code.

Cloud Server (ECS): Many corporate websites or business systems need to be deployed on independent servers on the public network. There are two types of servers: cloud servers and your own servers hosted in a data center. Cloud servers are relatively secure and easy to set up. It is easier to set up security, recover data (such as mirror services), and migrate data.

Server hosting : Some companies believe that cloud servers are not secure, their own servers are relatively private, and the performance of servers purchased by themselves is much better than cloud servers, so they choose to host their own servers. The security settings of self-hosted servers depend on the capabilities of network management engineers.
Cyber ​​attacks are growing at an alarming rate. Any business, regardless of size or industry, can be vulnerable to a cyber attack.

Don't wait until it's too late. Take action now to protect your small business from cyber threats. Invest in the right security tools, educate yourself and your team on cybersecurity best practices, and stay up to date on the latest threats.
