VRRP means Virtual router redudancy protocol. I am telling you in very general language not in too technical.

Assume that you have a two firewall in HA mode .

Ever since I wrote about the 34,000 MySpace passwords I analyzed, people have been asking how to choose secure passwords.
My piece aside, there's been a lot written on this topic over the years -- both serious and humorous -- but most of it seems to be based on anecdotal suggestions rather than actual analytic evidence. What follows is some serious advice.

I’m often asked: what’s the most common type of hacker and attack? Over time I’ve discovered that the general public holds a somewhat romantic image of hackers. One mental picture involves an emaciated young man in a poverty-stricken corner of the world. Greasy-haired and red-eyed, he types late into the night on an old TRS-80 workstation, trying desperately to get your American Express account number for nefarious purposes.
Another favorite image is of a cherub-faced pre-teen with extreme computer skills and little knowledge of law and order. Thanks to too much hardware and too little parental supervision, she creates a new virus that brings down every business on the Eastern seaboard.

IDS is an acronym for Intrusion Detection System. An intrusion detection system detects intruders; that is, unexpected, unwanted or unauthorized people or programs on my computer network.
Why do I need IDS? A network firewall will keep the bad guys off my network, right? And my anti-virus will recognize and get rid of any virus I might catch, right? And my password-protected access control will stop the office cleaner trawling through my network after I've gone home, right? So that's it - I'm fully protected, right?
Wrong!
