With the amount of malware currently prowling the internet it’s becoming increasingly important to protect your computer. Therefore I’ve separated my advice on how to stay safe online into two main sections. The first is the methods that I believe anyone from a novice to an expert user can use. The other section is aimed more at intermediate to advanced users. These methods may be more difficult to use, but your computer will be more secure.
When you want to send an instant message to someone else that’s on the same local network as you are, whether that be another family member or a co-worker in your office, why use an offsite chat server that leaves your messages open to interception by the company running the chat server or some other third party? This software will allow you to keep your local IM’s in your local network, and for added safety it also encrypts them! Plus, it supports multiple operating systems, unlike the proprietary chat client that might have come with your computer. It’s NOT for chatting with people elsewhere on the internet; if you need to set up secure connections with offsite chat clients then you may need to set up a private Prosody IM server. But for secure IM chats with people on your local network, this looks like just the thing!
