The Right Way to Set Up Your New Blu-ray Player

After having just gotten your new Blu-ray DVD Player, you will obviously be excited about testing it out. No doubt you will be anxious to see the glorious 1080p picture and High Definition sound quality. So the question is this: how to set up your new Blu-ray player to get the highest possible performance from it? Will it be as simple as connecting your DVD player? Will it be a breeze?


Tips for Digital Camera Beginners

For a beginner, it may seem a little overwhelming to pick up a digital camera for the first time.  After all, digital cameras are filled with features and options that tend, to at least suggest, they may be complicated.  But as with any technology that is relatively new, it is just misdirected fears and assumption.  Digital cameras do have one thing in common with their ancient cousin, the film fed camera.  Both of them only take a click of a button, and you have a picture.  Now is that sweet or what?  The difference is, with a digital camera, you can take the shot, see it immediately on a small LCD screen, and then keep it or re-shoot it.  Come on, you know thatð€™s cool. 


VoIP Security Considerations

During VoIP configuration/installation, it is important to establish security infrastructure including firewalls, VPNs, etc., to be capable of supporting the advanced security requirements for VoIP and be voice optimized at the same time. The VoIP security protocols dynamically allocate ports during call setup, requiring opening and closing of ports at the security gateway on demand. The protocol required the voice traffic inspection at the network and application level to address the challenges of VoIP protocols in Network Address Translation (NAT) environments.

Similar to other services using network, there are critical security vulnerabilities being identified for VoIP. It is important to have the IP-PBX and IP Phone firmwares always updated and patched for the latest security vulnerabilities. Regular security assessments of your VoIP infrastructure provide identification and remediation of such security flaws to avoid attacks and prevent outages. Your IP-PBX is the heart of your VoIP infrastructure and it must be updated and patched as necessary.

Since the VoIP gateways, servers and phone can be configured remotely, backdoor and front door access is sometimes enabled for ease of configuration. It is recommended to properly secure any remote access and configuration capabilities to individual VoIP devices to eliminate any security breaches. It is important to note that the endpoint credentials and administrator passwords on such devices are a very common avenue for attacks. In general, disable any insecure remote access features, such as FTP and Telnet, and disable local administration and management features.

If your VoIP traffic goes over the Internet, use encryption technologies like IPsec tunnels to secure the VoIP traffic. While many of the VoIP protocols include capabilities for encryption and authentication, most of them are optional. It is essential to establish secure tunnels for carrying the VoIP information streams (call signaling, call control and media) between sites.

Wherever possible, leverage VLANs to separate voice and data devices and traffic. This may have limited impact on security, however deploying VoIP devices on separate VLANs isolates data traffic from voice and signaling traffic and permits utilization of Quality of Service (QoS) capabilities.

When creating passwords for accounts, follow secure password guidelines such as making password long, using a combination of numbers and alphabets, not using common names, or same as the account numbers.
