SERVICES > SECURITY SOLUTIONS

Security solutions for WLANs are quite different than those for traditional wired networks. For that reason, you may have realized the need for a security solution for your WLAN, but have been unable to wade through the hundreds of pages of vague documentation on true wireless security architectures. Experts all agree that in no case should WEP be used to secure your network, and most will agree that a VPN is the best way to secure a wireless link. However, this area is emerging, and only a few vendors offer a truly secure VPN solution that is scalable and supports roaming users. Our consultants are specially trained in designing, installing and configuring advanced security solutions for WLANs.

Architecture Concerns: All wireless clients should be treated as unauthorized until proven otherwise. If your wireless access point is connected directly to your internal network, you are probably 100% to the outside world. Changing to a secure architecture should be your first priority. Our consultants will analyze your existing network architecture and ensure you're as secure as possible.

Authentication Solutions: The security dilemma is always a fight between cost and benefit, security and ease-of-use. While much more secure than static WEP, a lower end security solution uses remote authentication servers which authenticate clients while providing a rotating WEP key.

Virtual Private Network (VPN): The top end security solution -- VPN. Our top end VPN solution uses FIPS 140 standard encryption along with device AND user authentication. We can design several VPN solutions for you based on your needs, but rest-assured, our VPN solutions are industry leading and VERY secure.

The above diagram is only one example of a VPN solution for a WLAN. The above scenario offers an encrypted wireless interface that uses a non-WEP encryption scheme. Furthermore, with NAT (Network Address Translation) in place, the firewall can be easily configured to only accept inbound packets from your VPN gateway. Global Security Consultants can design enterprise wide VPN solutions or simple VPNs such as the diagram above indicates. We'll work with you to determine your business requirements in order to design the VPN that meets your needs.

Note: FIPS 140-1 is a U.S. government standard for implementations of cryptographic modules, that is, hardware or software that encrypts and decrypts data or performs other cryptographic operations (such as creating or verifying digital signatures). The FIPS 140-1 standard was created by the National Institute of Standards and Technology (NIST); it specifies requirements for the proper design and implementation of products that do cryptography.
