Security is a multifaceted issue that must be addressed to avoid abuse of your network from hackers and employees. While you are connected to the Internet your network is open to the public unless it is protected by a firewall. Networks that are connected to the Internet are vulnerable to malicious attacks from hackers and virus infection. A well configured firewall will block uninvited visitors whilst allowing remote access to authorised users and services. Many firewalls now offer a host of other advanced features such as gateway antivirus, spam filtering, content filtering and the ability to block specific applications such as instant messaging to add further protection and restrict how the Internet is used within the office. Internally, sensitive information such as personnel records, management reports and accounts data can be protected by configuring permissions that only allow access for those who are authorised. Passwords to access the network should be changed on a regular basis and should be sufficiently complex that they cannot be compromised. We can advise on all aspects of network security, firewalls, virus protection and implement a security policy to protect your data and systems.
IT professionals are concerned with the loss of control and security related to cloud computing. Private Clouds provide a handle for overcoming these challenges. As more of today’s businesses contemplate the need for ever increased investment in their IT departments, some aspects becomes clear: the need for effective ROI, increased security and more control of their resources, both internal and external. It is the loss of control and security which keeps many enterprises IT professionals awake with concern for the safety and administration of their growing computing needs. Private cloud computing is a new set of technologies and services available to help address, and ultimately eliminate the worries and concerns of your IT folks. From a public cloud perspective, most service providers are unable to relinquish the type and level of controls necessary to make network administrators satisfied with pushing proprietary data into the public domain. Even with the tightest security encryptions, concern for the flow and destination of applications, data, access have prevented large numbers of businesses from exploring the capabilities of cloud computing. However, with private cloud computing, control is brought back in-house to your IT admins along with heightened security and the ability to flow data precisely where it needs to go, either to destinations on your internal networks or along secure external channels. In order for businesses to cross the chasm from internal IT silos to the power and economy of cloud computing, they’ll need to take 3 steps: – Consolidate and Virtualize their applications: server, storage and network operations. – Automate and Optimize their virtual operations. – Enable federated access to resources on other public and private cloud operations. Vast majorities of IT budgets are spent on upgrading obsolete hardware. With new and improved computers, routers, switches, etc. constantly coming onto the market, the five years to obsolescence occurs quickly. With ROI and profitability, when it happens, taking at least a year and a half or longer, keeping the infrastructure up to date and in place can be a challenge for the bottom line. By consolidating operations, moving applications onto fewer sever sets and then creating virtual access to the resources, IT professionals are on track towards enabling their operations for private cloud computing. It is important for the enterprise that they are not simply tossing away resources which may have useful life in them. By enabling the consolidation of current assets, they are able to maximize investment in their current set up. As they see demand increase for more storage, application and network interactions, they are able to move into the second stage of the transition. By optimizing their operations, be it the freedom to increase hardware as needed, or provisioning applications and storage on demand the second stage is set. The enterprise now has the ability to increase hardware and provisioning when they need it. Whether set to automatically replicate services on demand or simply wrest control of decision making from cloud providers to the internal IT staff, virtual operations allow for the critical ability to make internal decisions for the betterment of the organization. With control and security firmly in place, when additional resources are needed, federated access is the way to scale operations to virtual infinite levels. The industry is still developing the protocols and universal security measures that will elevate trust levels. It is imperative that service providers continue to work together in order to enable interactivity. When your business needs to have access to on demand scaling of their web operations or research and development capabilities, being able to have unrestricted, pay as you go, federated access to deeper private clouds will allow you to compete at the highest levels. Your bottom line will also be affected by competitive service pricing and your company’s ability to ensure secure access and delivery of data and application interface. The migration from all internal IT departments towards some form of cloud computing is well on its way. Sandy Winslow is a writer on a variety of topics, including IT professionals struggling with loss of control and security challenges. Incorporating a private cloud system is the easiest way IT professionals can insure their system is safe and that they have full control.

VPN Technology Security risks are incurred when a teleworker or remote office uses broadband services to access the corporate WAN over the Internet. Full Post: VPN Technology Benefits Types VPN Gateway. To address security concerns, broadband services provide capabilities for using Virtual Private Network (VPN) connections to a VPN server, which is typically located at the corporate site. A VPN is an encrypted connection between private networks over a public network such as the Internet. Instead of using a dedicated Layer 2 connection such as a leased line, a VPN uses virtual connections called VPN tunnels, which are routed through the Internet from the private network of the company to the remote site or employee host. VPN Benefits Benefits of VPN include the following: Cost savings-VPNs enable organizations to use the global Internet to connect remote offices and remote users to the main corporate site, thus eliminating expensive dedicated WAN links and modem banks. Security-VPNs provide the highest level of security by using advanced encryption and authentication protocols that protect data from unauthorized access. Scalability-Because VPNs use the Internet infrastructure within ISPs and devices, it is easy to add new users. Corporations are able to add large amounts of capacity without adding significant infrastructure. Compatibility with broadband technology-VPN technology is supported by broadband service providers such as DSL and cable, so mobile workers and telecommuters can take advantage of their home high-speed Internet service to access their corporate networks. Business-grade, high-speed broadband connections can also provide a cost-effective solution for connecting remote offices. Types of VPN Access There are two types of VPN access: Site-to-site VPNs-Site-to-site VPNs connect entire networks to each other, for example, they can connect a branch office network to a company headquarters network, as shown in the figure. Each site is equipped with a VPN gateway, such as a router, firewall, VPN concentrator, or security appliance. In the figure, a remote branch office uses a site-to-site-VPN to connect with the corporate head office. Remote-access VPNs-Remote-access VPNs enable individual hosts, such as telecommuters, mobile users, and extranet consumers, to access a company network securely over the Internet. Each host typically has VPN client software loaded or uses a web-based client.
Adaptive Private Networking (APN) is a new technology that combines affordable and easily obtainable IP bandwidth sources such as broadband with high performance, more expensive WAN (wide area network) technologies like MPLS. The end result is next-generation enterprise WANs that can deliver 30 to 100 times the bandwidth per dollar while reducing WAN costs by anywhere from 40 to 90%. Additionally, APN technology offers greater reliability than any modern single provider Frame Relay or MPLS WANs. The Enterprise WAN market has not seen a lot of change for many years. In the early 1990′s, Frame Relay brought better bandwidth at a lower cost to IT Managers looking for alternatives to X.25 and point-to-point leased lines when building their WANs. Frame Relay, along with the comparably expensive single-sourced MPLS services are still the predominant technologies for corporate Intranet traffic today. Both technologies have the benefit of offering highly reliable (“3½ nines,” i.e., 99.95%, or better) service from a single carrier. However, the cost of these services comes at a price that is still equal to 1998 pricing on a cost-per-Mbps basis. The disconnect with regards to pricing becomes very noticeable when compared with the improved affordability of broadband connectivity such as DSL or Cable internet over the same period of time. These services are as cheap as $3 to $15/month per Mbps, and in some cases even less. However, the reason why enterprise businesses have continued to use more expensive solutions such as Frame Relay and MPLS is because the reliability of broadband and internet networks is no business quality and unlikely to ever get to a 99.99% reliability level. This is where Adaptive Private Networking bridges the gap. APN appliances leverage network bandwidth from multiple sources with a WAN, such as high-speed MPLS connections at central locations and broadband connections at branch locations. In the same way that a VOIP service such as Skype uses overlay networking techniques, APN does the same thing. In layman’s terms, this concept allows your wide area network to use large amounts of inexpensive broadband bandwidth combined with small amounts of more expensive MPLS or Frame Relay in order to deliver business-quality connections over the entire network at a fraction of the cost. The APN appliance performs real-time, per-packet traffic engineering and proprietary end to end algorithms to deliver reliability. The benefits of this technology are massive when consider the reliability and bandwidth required for applications such as VOIP and videoconferencing across an enterprise level corporation. Now a central office in New York can conduct videoconferencing with dozens of branches spread across the country using a hybrid consisting of large percentage of affordable broadband bandwidth and a small percentage of more expensive private bandwidth in order to deliver business quality connections at a fraction of the price. Adaptive Private Networking is a new and relatively unknown quantity, but one that is likely to be around for quite some time as awareness of its impact grows.
