Security Measure Question

Hi,

I need some advices from security gurus.

I have the requirement to keep my laptop/desktop open all the time 24*6. I can shut it down only once.

I would like to know for such a system what security softwares should i install to make my system hack free hassle free.

Kindly suggest.

 

Unplug the ethernet cord and turn off the wifi.

 

strong firewall to protect in/out bound

 

Is Windows a requirement?

 

I think a key question would be what is meant by keeping the laptop/desktop "open".

Some people keep computers (nearly) always on for local/home computing purposes and don't actually need to have an active Internet connection the entire time. If that is the scenario and the OP wishes, for whatever reason, to disable Internet access then the focus would be on ways to disable the Internet connection. The options for doing that would depend on whether or not they want to keep their local network up while their Internet connection is down. Manually switching power to a router would kill both local and Internet connectivity. Manually switching power to a broadband modem that is separate from the router would kill just the Internet connection. Plug pulling could work. Some routers support parental controls and specifically schedules for when local machines can access the Internet. Those approaches don't seem terribly appealing though. One could enable/disable the local adapter, but that would kill local network activity. What if we deleted/added the default gateway as desired? If the computer is setup to acquire IP Address and default gateway via DHCP the lease could expire and then what... it might re-add the default gateway when we didn't want it to? We could work around that by manually configuring local IP Address and default gateway?

I guess before musing too much we should probably get clarification from the OP. If he/she wishes to maintain the Internet connection while the computers are up then I think the objective boils down to how to generally secure one's local network and computers against Internet threats.

 

Assuming that you're just talking about the standard/typical risk of malware exposure while connected to the internet, and you're not at any special risk of a targeted attack, then there really isn't anything particular that you need to do differently; just a good firewall that's properly configured (all ports closed, if possible) and keep everything updated.

These days a great number of people are always connected and always on; it doesn't increase risk, in any real sense, as long as you have a router and/or firewall. Connecting through a router, however, is an easy way to ensure permanent inbound 'protection,' regardless of what happens on your PC.
