Demand for mobile and remote access to business networks has increased dramatically. Even the most basic virtual private network (VPN) technologies are so accessible and affordable that there is no good reason for failing to utilize them. That said, the real question for businesses is which type of VPN to implement: Standard IPSec (Internet Protocol Security) or secure-sockets layer (SSL)?
The security of VoIP networks have been the subject of much debate. With internet hacking at an all-time high these days, VoIP users have every right to be concerned their user information, phone services or even their phone calls are being listened to. Because of this risk, individuals and businesses find this one of the stumbling blocks to VoIP implementation.
Since most VPNs operate over the Internet, businesses must deal with the challenge of keeping the transactions and data confidential and protected. This is where SSL encryption comes in encryption scrambles the data and keeps it unreadable by unauthorized users. Each SSL Certificate consists of a public and private key the public key encrypts information and the private key decrypts it. When a Web browser points to a secured domain, an SSL handshake either authenticates the server and the client or blocks unauthorized users.
Businesses that have limited budgets and/or those that do not share highly sensitive data may opt for a standard VPN because of cost; this technology is virtually free. In fact, most operating systems have built-in VPN protocols, but you typically get what you pay for here. Such protocols often rely on little more than usernames and passwords, they usually lack robust authentication and encryption components, and they can easily become open doorways into corporate networks. Furthermore, standard VPNs require the deployment of software and clients an administrative headache at best.
SSL VPNs use the same encryption protocols as many e-commerce sites and Web-enabled applications. They are therefore more compatible with the networks through which your remote users connect. Further, SSL is simple to install and leverages firewall ports already opened to secure Internet traffic, enabling users to connect to a network securely via a standard Web browser, without the need to install special software on the client (e.g., desktops or laptops).
SSL Encryption for Data Protection
Since most VPNs operate over the Internet, businesses must deal with the challenge of keeping the transactions and data confidential and protected. This is where SSL encryption comes in encryption scrambles the data and keeps it unreadable by unauthorized users. Each SSL Certificate consists of a public and private key the public key encrypts information and the private key decrypts it. When a Web browser points to a secured domain, an SSL handshake either authenticates the server and the client or blocks unauthorized users.
The remote access market is enormous, even overwhelming at times. According to IDC, 28 percent of all firms, or 2.4 million companies, have some sort of branch office. As remote access continues to grow, SSL will be in greater demand. Through SSL and effective key management, IT managers and end-users alike can share information securely and conveniently.
Security of VoIP Network
The security of VoIP networks have been the subject of much debate. With internet hacking at an all-time high these days, VoIP users have every right to be concerned their user information, phone services or even their phone calls are being listened to. Because of this risk, individuals and businesses find this one of the stumbling blocks to VoIP implementation.
Since VoIP calls are made digitally, they are easier to tap into than a traditional phone line. So someone with the right access and knowledge can listen to what you have to say. While most residential VoIP users, unless they are sharing financial data, would find it embarrassing if they knew someone was listening to their calls, for businesses, tapping into their VoIP system could be disastrous.
No matter what the stakes are, privacy is important. Even though the thought of snooping into your business or residential VoIP network seems violating, it's a fairly simple task to ensure your VoIP's security.
The following are application choices for encrypting your VoIP network:
Zfone: Check out Zfone, which is software that secures your VoIP network by encrypting calls. They offer a free beta version which is easy to install and use. The downside is only calls made to other Zfone users are protected.
Service Provider Encryption: Check with your VoIP service provider to see if they offer their own encryption software.
Transport Layer Security & IP Security: Authenticate your server with Transport Layer Security (TLS) and IP Security (IPsec). These are two simple encryption methods for VoIP calls. TLS encrypts data transferred between two applications while IPsec encrypts information for the devices and their applications.
Secure Real-Time Transfer Protocol: Authenticate Secure Real-Time Transfer Protocol (SRTP). SRPT protects VoIP calls by creating an encryption key for each call, without affecting call quality.
Virtual Private Network: Enable Virtual Private Network (VPN) Encryption. While your business's VPN should come with a built-in encryption device, it will only secure data from gateway to gateway. Also, your LAN calls will require additional security.
Session Initiation Protocol: Session initiation protocol is the standard choice for VoIP and other IP communications. VoIP network administrators are concerned with allowing SIP calls through a firewall while securing the network. SIP works with other protocols like HTTP and SMTP to integrate the much needed security measures. SIP trunking can securely connect SIP users with callers on a traditional phone system.
In summary, make sure your VoIP network uses one or more of the above mentioned encryption applications. Your personal or business information is only meant for those you want to share it with. Take the necessary steps to prevent your information from getting into the wrong hands. Contact your VoIP service provider today to ensure your VoIP network has a secure connection.
