Internet security

Some Do's and Don'ts for internet users everywhere - you may find something on this list that you do, but shouldn't...

• Don’t re-use your email password - if you log into a third party site with your email address and the same password that you use for your emails (ie. your hotmail, gmail, etc..) that third party site has both your email address AND your password...
• Use two-factor passwords when you can  - I keep an 'offline' (ie. a notepad in my office) record of my passwords. I tend to have a list of about three or four different words and about three or four different numbers that I use - but I will still use totally random configurations just to keep things fresh - that's when you need a notebook or pother physical record (as opposed to a spreadsheet which might be accessed on a PC)
• Don’t use the same username everywhere people don’t realise that people can use Google to connect accounts accross all the different networks they visit, and then work out a way in. For instance Facebook can give visitors clues as to pets names childrens names, car type - all things that can give a clue to passwords. Forums will do the same, if you are logged into a Yamaha forum - what's the betting that one of your passwords is a favourite Yamaha model??
• Keeps plug-ins such as Flash and Java up to date as many of them are to guard against vunerabilities
• Be careful about who you friend on Facebook 
• Don’t trust public wi-fi - fine to use it now and again, but just be careful about what might be accessible on your laptop - and even worse, your phone (phones are generally less well-protected than computers)...
