One of the biggest threats to a company using remote workers is the possibility of hackers gaining access to the company system.
If you don't think this can happen to you or your company - think again. In October 2000, Microsoft faced this situation when a hacker gained access to a remote user's PC and was able to enter Microsoft's internal network.
The use of a VPN for remote access can be a great solution for allowing or increasing the use of remote workers. It is an economical method of allowing access, but the problem of course is controlling the access. The initial purpose of VPNs were for within interoffice communication. The threat of outsiders gaining access to the company's system was low when used only in-house.
As more companies use their VPN to allow remote workers to access the company system they must be aware of the consequences and be prepared to prevent unauthorised entry.
One method used to access corporate networks is TCP port redirection. A hacker breaks into a PC once, sets up a back door and then uses the hacked PC as a router to the corporate network.
The increased use of broadband access such as DSL and cable access has made it easier for hackers to get into PCs. When a computer is always on it increases the chances that someone will gain access.
How can you help prevent and possibly eliminate the chance your remote workforce will be hacked?
- Disable file and print sharing on Windows systems.
- Shut down the DSL or Cable access when not in use.
- A VPN on its own is not enough security.
- Installation of firewall software is required. Intrusion detection software is a wise idea as well.
- Home networks must use firewall software to prevent any of the networked computers from being accessed by a hacker, who then gains access to the company system from that computer.
- Remote workers who regularly use hot spots and hotel provided Internet access must be sure to have firewall software installed and running.
- Educate all staff to the importance of using firewall software and not become lax in this regard.
Promoting the use of remote work is a goal that is important for many reasons, but it is important to remember that the security of the company system is of utmost importance.
Investing in firewall and intrusion detection software is the best solution to prevent unauthorised access to your corporate system.
