Do I need a router for protection?

    Do I need a router for protection?

    My questions: Do I need a router for protection? Will it significantly
    improve my protection? When does "The Law of Diminishing Returns" apply if
    it would help just a little?

    I have been reading about security. One site said a router makes my
    computer "invisible" on the internet. And another said "In very basic
    terms, a router will automatically reject unsolicited inbound communications
    to your PC. It will not reject solicited, but malicious, communications.".

    I am running PC Tools Firewall Plus Free as my firewall and Avast 5 for
    malware protection. I have spent some time to learn how to work theses apps
    and set to most secure. PC Tools Firewall Plus Free was rated #2 firewall
    at matousec.com. I always use my computer in standard user account. If I
    need to use admin account I unplug network cable if I do not need internet
    for what I am doing. I looked up the specks of my cable modem and it is not
    a router. I use a direct network wire from modem to my computer. (I do not
    use anything "wireless" yet)

    I tested my firewall at grc.com ShieldsUP! It passed every test except it
    failed the ping test because it responded to a ping. I also tested at
    grc.com LeakTest v1.2 and it failed in a strange way. When firewall alerted
    me to LeakTest v1.2 with the usual pop up warning "Allow or Block", I
    obviously blocked it as instructed by leaktest instructions, and immediately
    LeakTest v1.2 claimed it connected to grc.com and stated I failed the test.
    I suppose this is off subject because it is a matter to take up with PC
    Tools and grc.com.

    Background info: Desktop AMD 4400+ 64X2 4GB memory 320GB HD Acer
    (AM3100-U3201A) purchased new February 2008 -- 32-bit MS Vista Home Premium
    SP2 -- MS auto updates on. Comcast ISP 12mbps service W\ Motorola SURFboard
    SB5101 Cable Modem direct to computer. No other switches or routers or
    wireless or phone line or any other networking hardware hooked up to this
    computer.

    Thanks for the help

    IMO its a user who causes an infection, in nearly all cases, by dowloading /
    installing something from a 'bad' scource.
    A NAT enabled router will basically add a further 'firewall type'
    enhancement to your connection.
    Provided you have a decent firewall and AV, occassionally run a malaware
    scanning tool you will be fine for any normal useage, and should'nt become
    too paranoid.

    The little help an actual firewall device gives you is in the fact that
    if your machine gets compromised by something that you invited in, it
    becomes very difficult for that malware to compromise the device. The
    firewall application (personal firewall / software firewall) runs on the
    now compromised machine and can be circumvented in most cases if the
    malware was written to do so.

    A device sitting between networks (even between the internet and a LAN
    with only one member) is in a unique position to "filter" communication
    packets. The most basic is SPI (Stateful Packet Inspection) where the
    "state" of a packet is checked to determine whether it is an
    initialization packet (sent to initialize a communication) or a
    subsequent packet (sent as a response as in an ongoing communication).
    Basically, if you run a server of some kind, you need to be able to
    respond to incoming init packets - otherwise it is best to drop them
    into the bit bucket (null device).

    Personal firewalls attempt to implement this on the computer that they
    hope to protect, although they no longer have that aforementioned
    "unique position". If you download and execute malware with sufficient
    privilege, you usurp the so-called firewall.

    I'm on Cable too and read the replies by "DL" & "FromTheRafters" and agree
    with their comments although I do use a Router myself but mainly due to a
    Router was already available.

    I'm elderly and not using anything "wireless" either, I don't think it will
    catch on, but then I didn't think color TV would catch on either. ;-)

    >I tested my firewall at grc.com ShieldsUP!
    ShieldsUP! Excellent web site I also go there, usually weekly for a check.

    Just a couple more suggestions:

    I use the free Web Proxy "Privoxy" <http://www.privoxy.org/> Privoxy is a
    non-caching web proxy.

    Privoxy blocks advertisers when I'm using my browser to view web sites.

    Using Opera I have a button on the "Personal Tool Bar" where I can click to
    enable/disable Privoxy.

    Also Opera is set to delete cookies each time I close the browser.
