The Wifi era was begun, got again bright the development wifi in Indonesia since being released by him the frequency 2.4Ghz his use by the government, so various networks wifi/hotspot began to be widespread in cities in our homeland, but this development was marked concerned by the owners hotspot, frightened of being unaware here!! , his question was how pacified or minimised resiko the security from hotspot we, we gave the suggestion along with this:
1. Activate the use enkripsi WEP and WPA, the use was so that not just anyone could enter, with this system of each computer had the speaking authority with the it’s fellow member worgroup, outside the member “no entry”, WEP and WPA also mampu pacified from the act”tapped”the data traffic in the network wifi you, so the data -the data like username, paaword, the account of the bank, the love letter etc., God Willing could be safe, better activate WEP in the level security that the example maximum 128 bit, and the substitute it’s password periodically, the example 3-4 days very much.
5. The last, often read in the internet to sites that discussed security, who knew was bug in driver your access point, like that just-barupf this happened in driver wifi notebook the Apple make that could in attack in a manner re-beads, when necessary update your firmware device wifi, but be careful update firmware could cause the risk of equipment damage, looked for information beforehand.
2. Hide Service Set Id (SSID) in your Access Point, because with open SSID, then was easy to be found by the other person that did scanning the network wifi, so this person had the bad intention to hack your hotspot you, do be carefull !!
3. Register MAC address of your computer/laptop client, in fitur MAC Address Filtering in your access point, so that the other company that want to accessed hotspot you could be blocked.
4. Scan your network class, who knew, there is other ip address that was foreign that was accessing or residing in your network, because that used ip address static, don’t be dynamic, it would also be better if used ip address that was different between point access and and the local your network/gateway
