Googled up the concept, did you? I checked, that source comes up first for "security hide ssid" in Google. I'm glad you're learning something. As I said, and as your source confirms, both can easily be bypassed by an expert. But look at more sources. Both are still commonly accepted security practice.
True, it only takes a little extra effort by an expert to bypass SSID hiding and MAC filtering. But it's a good thing to force more effort upon your attacker. It quickly eliminates those going for the low-hanging fruit in your neighborhood, or just those who are less talented. It slows drive-bys and generally makes you the least attractive target of the 10 more open WiFi networks available from that spot in your neighborhood.
A dedicated hacker with resources can quickly bypass WPA2 encryption using a rainbow table attack if you didn't change the SSID (assuming average password length). But changing the SSID only slows him down in that same scenario, as a brute force attack can still be done with GPUs. Does that mean you shouldn't change the SSID from the default? No, changing the SSID is recommended because it slows the attacker down.
Defense in depth. Learn the concept. Removing even layers you know can be bypassed still lowers your depth.
If you want to talk counter-effective security measures, think of the Club (steering wheel lock) in modern cars. The thief quickly cuts through the steering wheel with a small hack saw to take the Club off. At that point, what is the Club to him? What you just left in your car for the thief to use is a hardened-steel bar that he can use to gain great mechanical advantage against the steering wheel to break the internal steering wheel lock. The Club is actually a benefit for the thief because it saves him from having to suspiciously walk around with a long leverage bar. In this scenario, the Club actually makes your car MORE attractive to the thief and likely to get stolen.
But even that negative scenario assumes a pro is going after your car. An amateur looking for a joyride is likely to pass over your car and go for your neighbor's if you have a Club.
What the he!!. You act as if you are superior when you state what is a known flawed concept of hiding the SID. You used that as proof that obscurity is a valid security concept when any real IT person knows it’s a joke.
So I used bing to find a source to backup what I already knew. Sorry I don’t have all these websites/links memorized, but I did know you were wrong as you ever were with that comment and I just wanted to give you a little backing to shut your pie hole over the topic. And your response has validated that I was correct and you don’t know what you’re talking about in terms of security.
Actually it's not recommended and it breaks the RFC. Some computers will stop working on such networks because it doesn't follow the RFC so it stops talking on the network.
Clearly you just googled this to find out more info on it and you completely missed the point.
