I have a topic for you about how can you protect your server from hackers with screenshots.
1-Invest in the firewall. After installing your server, the closest thing you need to do is creating a firewall. Firewalls are programs in which information entering and exiting your computer is filtered.
There are many firewall applications available on the Internet and local computer stores, but even less experienced hackers can bypass them. I recommend you guys investing in a well-developed and reputable application to provide the highest level of security.
Firewalls are installed just like any other program and are more than capable of protecting small-scale servers. Corporate firewalls must be installed by a software security specialist.
2-Protect your codes. When creating your program codes for applications that intended end users interact with, make sure that appropriate error traps are placed within the application. Hackers often modify SQL injections or an application's code via URL or SQL forms.
Your server becomes vulnerable to hackers when your program lacks a margin of error that can close gaps to which SQL queries can be added.
3-Use an SSL. Secure Socket Layer is a Internet security protocol that protects your server by ensuring every info that goes into or leaves from server are safe and can't be accessed by any third party users.
-Hackers can easily get what they want from your server if you don't have SSL certificate. Here's my recommendation: SSL Information and FAQ
4-Limit all uploads. End users have to accept their datas for your server can gather info. Even if uploads are necessary, nevertheless you should limit it.
5- Use strong passwords. Passwords are basic tools that saves your server from hackers. Using password can restrict unauthorized access to your system. Hackers who don't have comprehensive technical knowledge will have some troubles while penetrating your system.
6-Keep private your server's locati0n. Don't reveal your server's physical locati0n as well. Hackers who don't have access to your digital security will try to direct access to your host computer physically.
7-Limit the access. If you can't keep your server's ******** private for offices and jobs deliberately given to people, make sure that only authorized personnel can access the server room.
8-Av0id providing any digital information about your server. Hackers can easily enter your system servers by only knowing IP addresses. Ensure that such digital information about your server is known only when needed, as it should remain confidential.
Hire someone professional. There are plenty of Network and Internet security specialist. If you realized that you're not enough for technical stuff and you have enough money to do that, i recommend you to hire someone who knows his job. Have a nice day..
