Network Security & Connectivity
The challenge of keeping your network secure has never been greater, or more important than it is today. Unauthorized network access can expose or destroy your proprietary data, negatively affect company productivity, and irreparably harm your relationships with customers and business partners.
Computer Maintenance Service helps organizations of all sizes to evaluate the latest network security technologies and integrate the right safeguards within all the necessary areas of their network. Not every client is the same. The security and connectivity required by a large doctors office is completely different than that needed for a user in a home office environment. CMS has partnered with a number of industry leading vendors to help properly recommend and deploy a comprehensive networking solution for your organization. Our engineers can also work with your internal staff to implement best security policies and practices to efficiently combat ongoing threats. In addition to traditional wired networks CMS specializes in a number of networking technologies to help reach your connectivity and security goals.
Firewall
A network firewall protects a computer network from unauthorized access. Network firewalls may be hardware devices, software programs, or a combination of the two.
Network firewalls guard an internal computer network (home, school, business intranet) against malicious access from the outside. Network firewalls may also be configured to limit access to the outside from internal users.
VPN
A VPN supplies network connectivity over a possibly long physical distance. In this respect, a VPN is a form of Wide Area Network (WAN). VPNs enable file sharing, video conferencing and similar network services. Virtual private networks generally don't provide any new functionality that isn't already offered through alternative mechanisms, but a VPN implements those services more efficiently / cheaply in most cases.
A key feature of a VPN is its ability to work over both private networks as well as public networks like the Internet. Using a method called tunneling, a VPN use the same hardware infrastructure as existing Internet or intranet links. VPN technologies include various security mechanisms to protect the virtual, private connections. Let CMS help with your remote connectivity needs.
Wireless Lan
Unfortunately, no computer network is truly secure. It's always theoretically possible for eavesdroppers to view or "snoop" the traffic on any network, and it's often possible to add or "inject" unwelcome traffic as well. However, some networks are built and managed much more securely than others. For both wired and wireless networks alike, the real question to answer becomes - is it secure enough?
Wireless networks add an extra level of security complexity compared to wired networks. Whereas wired networks send electrical signals or pulses of light through cable, wireless radio signals propagate through the air and are naturally easier to intercept. Signals from most wireless LANs (WLANs) pass through exterior walls and into nearby streets or parking lots.
Network engineers and other technology experts have closely scrutinized wireless network security because of the open-air nature of wireless communications. Overall, conventional wisdom holds that wireless networks are now "secure enough" to use in the vast majority of homes, and many businesses. Security features like 128-bit WEP and WPA can scramble or "encrypt" network traffic so that its contents can not easily be deciphered by snoopers. Likewise, wireless routers and access points (APs) incorporate access control features such as MAC address filtering that deny network requests from unwanted clients.
Obviously every home or business must determine for themselves the level of risk they are comfortable in taking when implementing a wireless network. The better a wireless network is administered, the more secure it becomes. Let CMS help with your wireless needs.
