... I called two sections for this topic: 1. General guidelines. 2. OS specific.
By now, I'm going to write about (1). I decide to write as simple as & short so you
can read as fast as.You can do (2) with refer to your OS website,... .If desired ask here.
1. General Guidelines:
a) For CD/DVD/Local HDD installation, unplug the network connection GOTO (c) !
b) If you cannot unplug the network connection because of the network installation, then do at least one of the following:
- Put system behind the firewall.
- Using private IP addresses.
- Create private segmentation using VLANs or so on.
OR any way that you cann't see the Internet!
c) Intall the Antivirus.
d) If exist enable the OS specific firewall, such as WindowsXP firewall GOTO (f).
e) Install personal firewall (Optional - if enterprise firewall exist & the system is behind it).
f) Apply any service pack & update, so on, which can be found local or on private network.
g) Plug the network connection & connect to the Internet then update the system online.
