Use a strong Wi-Fi security password: Even if you decide to set up WPA2-Personal (PSK) security on your wireless router, you're still at risk if you make a weak password that can be cracked. To ensure that malicious parties cant break into your Wi-Fi, use a complex password. You can use up to 63 characters, including lowercase and uppercase letters, numbers, and symbols. Dont use any recognizable words or phrases; gibberish like a8F#wM1(C9*!q$JyP@i^ is ideal. And so you dont forget it, you might write it on a sticky note and attach it to the bottom of your router, or save it on your desktop PC in a Word or plain-text file.
Password-protect your smartphone and tablet: Dont forget about the security of your mobile devices. Losing your smartphone or tablet can cost you money, time, and privacy. Your first line of defense should be to set a lock-screen PIN or password on your phone or tablet so that other people cant use it if you lose it. And if your smartphone or tablet supports encryption, you should turn the feature on so that a thief cant retrieve your personal data from the device without considerable effort.
Install security apps on your phone and tablet: No-cost, easy-to-use security utilities such as Avast Free Mobile Security, AVG Mobilation Anti-Virus Free, or Bitdefender Mobile Security can help you locate and secure your smartphone or tablet if it is lost or stolen. Most of these security apps let you log on to a website where you can see the location of your lost device on a map, make it scream or sound an alarm (useful if you lose it in between couch cushions), lock it in case you dont have a PIN or password currently set, and even wipe the data if you think you wont be getting it back. These apps also have antivirus features to help block mobile malware, an emerging threat.
