As homes and offices incorporate more internet-connected devices, from laptop computers to off-the-shelf devices, the cyber-vulnerabilities continue to multiply. Cyber researchers at Ben-Gurion University of the Negev suggest that this “Hacktober” during Cyber Security Awareness Month, is an excellent time to make a few simple changes to increase your network’s safety and security.
“There’s a wide range of steps consumers can easily take, though some require a bit more focus or technical prowess,” explains Dr. Yossi Oren, a senior lecturer in BGU’s Department of Software and Information Systems Engineering and head of the Implementation Security and Side-Channel Attacks Lab at Cyber@BGU. “In previous research we found that internet-connected devices such as baby monitors, home security cameras, doorbells, and thermostats were easily hacked by our researchers. Password protection and updated devices are just as important in a smart home as they are on a computer or mobile phone.
BGU’s Hacktober Tips for Product Security
With the goal of making consumers smarter about smart homes, BGU researchers offer a number of tips to keep families and their IoT devices more secure:
- Never use the same password on multiple websites or online services. Both Apple and Google offer free password managers that can take care of your passwords for you, and even automatically suggest strong passwords that are hard to crack.
- Turn on “two-factor authentication” to prevent hackers who’ve stolen your password from logging into your Facebook or Google account. Two-factor authentication sends a text message with a login code to your phone to verify it’s you.
- On the heels of the recent Facebook hack, in addition to changing your password, use the Facebook settings screen to review the list of apps and websites which you granted access to your data. Remove any apps or websites you don’t recognize and trust.
- Don’t fall prey to clever phishing scams that ask for payment and indicate they have an old password that you recognize. It was likely bought on the illegal “dark web.”
- Do cover your computer camera with tape or use a specially made camera cover to prevent prying eyes.
- Buy IoT devices (cameras, baby monitors, etc.) only from reputable manufacturers and vendors. Change the admin password as soon as you can connect it. Annually check for security updates which you download.
- Avoid buying used IoT devices like routers or cameras. They could already have malware installed.
- Call your internet service provider and request an updated router. Many are years old and don’t have the latest security updates. Change the WiFi password on your home router.
- Automatically back up your data—pictures, contacts and documents. If a computer is compromised, it may be easier to just reformat it than to find the malware, and it will allow your devices to function better.
- Evaluate your family’s cyber health. While you yourself may be relatively cyber safe, make sure others in your family, like an elderly parent or teenager, are taking similar precautions.
“In only an hour or two, most of these steps can be accomplished, saving you significant headaches, serious theft and the loss of privacy or priceless data,” Dr. Oren says.
