There are a lot of firewall applications available on the Internet and from local computer stores, but even the less experienced hackers can get past these. Invest in a well-developed and reputable application to ensure the utmost security. Firewalls are installed just like any other programs and are more than capable of protecting small scale servers. But if you’re running several mainframes, enterprise firewalls need to be installed by a software security specialist.
When your program lacks error trappings that can cover loopholes where SQL queries can be injected, your server becomes a sitting duck to hackers.
Hackers can easily get the information from your server if it does not ask an SSL certificate. You can take advantage of this technology for your server by visiting the SSL website (http://info. ssl. com/) and availing its service.
To do this, format forms properly to make sure that only the required data gets into the system.
Make sure that the password you make is complex and very hard to crack. Using combinations of special characters, mixed cases and numbers will make it harder to break.
Lock your server in a closed, cool, and suitable room, and provide security keys only to those that need to have access.
Salaries of these kinds of personnel range from a few thousand to even hundreds of thousands of dollars, depending on the skill level. Though it may sound costly, it will prove to be worth it, especially if you’re housing very valuable information on your servers.
