Firewall Protection

  • Keep Those Viruses & Hackers Out!

    Many companies are implementing the high-speed ADSL internet solution for faster and much improved communication transport for their internet transactions. Since it vastly speeds up internet downloads and uploads, it greatly assist in downloading large service packs and essential hot fixes from Microsoft and Symantec Antivirus to update critical system processes.

    However, since ADSL is an always-on technology and is less susceptible to disconnection from your Internet provider, there is a greater chance of a hacker using various network scanning tools to detect open ports and connections on your computer systems. A clever attacker can easily scan available open ports on your connection and send a worm written to intrude your network and wreak havoc causing instant Denial of Service (DOS) attacks and unnecessary downtime. Programs are being written to exploit operating system vulnerabilities as we have seen in the Blaster Worm. Using a known operating system exploit in Windows 2000, XP and 2003 server, this DOS attack caused severe problems last month with both corporate and home user systems. To further demonstrate how fast an unprotected system can be attacked, if you place any computer on the Internet without the Blaster patch, we guarantee it will be hit in less than five minutes!
