Wireless Connections and Bluetooth Security Tips
Wi-Fi networks and Bluetooth connections can be vulnerable points of access for data or identity theft. Fortunately, there are many ways to decrease your chances of becoming a victim.
Encryption is the best way to keep your personal data safe. It works by scrambling the data in a message so that only the intended recipients can read it. When the address of a website you're visiting starts with "https" instead of "http," that indicates encryption is taking place between your browser and site.
The two most common types of encryption are Wired Equivalent Privacy (WEP), and Wi-Fi Protected Access (WPA). The strongest one commonly available is WPA2, so use that if you have the option. Home Wi-Fi systems and public Wi-Fi access points, or "hotspots," usually will inform you of the encryption they use.
Public Wi-Fi Access
Many Wi-Fi users choose to use public networks instead of their devices’ data plans for accessing the internet remotely. But the convenience of public Wi-Fi does not come without risk. If you’re not careful, a hacker can access your connection in a matter of seconds, and potentially put sensitive information stored on your device and in online accounts at risk. Here are some steps you can take to minimize the risk:
- Check the validity of available Wi-Fi hotspots. If more than one hotspot appears claiming to belong to an establishment that you're in, check with the staff to avoid connecting to an imposter hotspot.
- Make sure all websites you exchange information with have "https" at the beginning of the web address. If so, your transmitted data will be encrypted.
- Install an app add-on that forces your web browsers to use encryption when connecting to websites -- even well-known sites that may not normally encrypt their communications.
- Adjust your smartphone's settings so it does not automatically connect to nearby Wi-Fi networks. This gives you more control over where and when you connect.
- If you use public Wi-Fi hotspots on a regular basis, consider using a virtual private network, which will encrypt all transmissions between your device and the internet. Many companies offer VPNs to their employees for work purposes, and individuals may subscribe to VPNs on their own.
- When transmitting sensitive information, using your cellphone data plan instead of Wi-Fi may be more secure.
Bluetooth Security
Bluetooth connections to your mobile devices can be very useful, from connecting a wireless headset to transferring files to enabling hands-free calling while you drive. Most of the time, a user must allow a Bluetooth connection to occur before data is shared – a process called “pairing” – which provides a measure of data security. But just like Wi-Fi connections, Bluetooth can put your personal data at risk if you are not careful. Here are some steps you may wish to take when using Bluetooth:
- Turn Bluetooth off when not in use. If you keep Bluetooth active, a hacker may be able to discover what other devices you connected to before, spoof one of those devices, and gain access to your device.
- If you connect your mobile phone to a rental car, a good deal of data from your phone may get shared with the car. Be sure to unpair your phone from the car and clear any personal data, such as call logs and saved numbers, from the car before you return it. Take the same steps when selling a car that has Bluetooth.
- Use Bluetooth in “hidden” mode rather than “discoverable” mode. This prevents other unknown devices from finding your Bluetooth connection.
Home Wireless Network Security
Home wireless networks are exceedingly popular, in large part because they enable computers and mobile devices to share one broadband connection to the internet without having to use up minutes on a cellular data plan. They also provide the convenience of not having to connect all these devices with wires to do so. But like all other wireless network technologies, home wireless networks present vulnerabilities that could be exploited by hackers to obtain sensitive data and commit other crimes. To help protect your home wireless network from unwanted users, consider the following steps:
- Turn the encryption on. Wireless routers often come out of the box with the encryption feature disabled, so be sure to check that encryption is turned on shortly after you or your broadband provider installs the router.
- Change the network’s default network name, also known as its service set identifier or “SSID.” When a computer with a wireless connection searches for and displays the wireless networks nearby, it lists each network that publicly broadcasts its SSID. Manufacturers usually give all of their wireless routers a default SSID, which is often the company’s name. It is a good practice to change your network’s SSID, but to protect your privacy do not use personal information such as the names of family members.
- Change the network’s default password. Most wireless routers come with preset passwords for administering a device’s settings (this is different from the password used to access the wireless network itself). Unauthorized users may be familiar with the default passwords, so it is important to change the router device’s password as soon as it is installed. Again, longer passwords made up of a combination of letters, numbers and symbols are more secure.
- Consider using the MAC address filter in your wireless router. Every device that can connect to a Wi-Fi network has a unique ID called the “physical address” or “MAC” (Media Access Control) address. Wireless routers can screen the MAC addresses of all devices that connect to them, and users can set their wireless network to accept connections only from devices with MAC addresses that the router will recognize. To create another obstacle to unauthorized access, consider activating your wireless router’s MAC address filter to include your devices only.
- Turn off your wireless router when it will not be in use for any extended period of time.
- Use anti-virus and anti-spyware software on your computer, and use similar apps on your devices that access your wireless network.
Passwords
Remembering all of your assorted passwords can be a pain. Web browsers and other programs may offer to remember passwords for you, which can be a significant timesaver. However, certain password shortcuts can leave you less safe secure. The following best practices may help keep your personal information safer:
- Don’t use the same password for multiple accounts, especially for the most sensitive ones, such as bank accounts, credit cards, legal or tax records and files containing medical information. Otherwise, someone with access to one of your accounts may end up with access to many others.
- Don’t have your web browser remember passwords and input them for you, particularly for your most important financial, legal and medical accounts. If an unauthorized person gains access to your computer or smartphone, they could access any account that your browser automatically logs into.
- Don’t use passwords that can be easily guessed, such as common words and birthdays of family members. Instead, use a combination of letters, numbers and symbols. The longer and stronger the password, the safer your information.

Staying Secure While Shopping Online
It is that time of year where so many people prepare to purchase gifts for friends, family, and loved ones. Though it can be convenient to avoid the lines and rush for that latest Black Friday deal by shopping online, this also carries some risk. Cybercriminals are always working to steal your personal and payment information and the holiday shopping season is the perfect opportunity for this to happen. By following a few key practices, you can greatly lower your chances of becoming a victim of identity theft or fraud.
Choose Trusted Online Retailers and Apps
Always shop only with trusted online retailers. That means using a retailer you already know or one that is verified through another trusted entity. If you find a new possible shop to do business with, but are unsure about its reputation, try to find reviews from trusted sources such as the Better Business Bureau. It is important to stick to trusted review sources because there are several ways to fake online reviews, and there are places where cybercriminals can pay other criminals to post positive reviews. Even though an untrusted site might have the best prices, it is worth it to use a trusted online shop that is known to safeguard your information and purchases.
The same advice applies when downloading apps to help with your online shopping. Whether you are downloading a store app to get a coupon, a deal aggregator app to comparison shop, or a reward app that ensures you get points or cashback, it is important to stick to trusted apps from known developers. Unfortunately, fake apps appear in the app stores, purporting to be from a trusted source while other apps exist to capture your data without providing the services they claim to support. You can avoid many malicious apps by downloading your apps from Google Play, Apple App Store, Microsoft Store, or another trusted platform, selectively choosing which apps to download, and making sure you carefully read the permissions and app reviews.
Secure your Device, Connectivity and Accounts
Keep your devices up-to-date, especially those you shop and bank with – Simply updating the device that you use for conducting your online shopping is a key cybersecurity practice. By keeping the device up-to-date with current patches and software, you ensure you have the manufacturer’s latest security fixes in place.
Never use a public computer when shopping or banking – Using a public computer, like those found at libraries, can expose you to greater risk. It is best to use a trusted home device and network for anything involving financial transactions.
Never shop or conduct banking on unencrypted or public Wi-Fi – It is best to always conduct financial transactions or log on to sensitive accounts via a trusted Wi-Fi networks. Ideally, this should be from your home network, which should require a password and use WPA2 encryption.
Look for the lock icon on your browser - When a site has a lock icon on the browser window, or in the URL bar, it indicates that your communications with the site are encrypted. If you do not see a lock, look for “https” at the beginning of the URL, as this is the same thing as the lock.
Check out as a guest – By checking out as a guest, you prevent the online retailer from storing your personal account and financial information. This minimizes the amount of information that could be lost if the retailer is compromised. If you have or need an account with a retail website:
- Use a strong password – Be sure to use a strong, unique password. Always use more than ten characters, with numbers, special characters, and upper and lower case letters.
- Don’t save your payment information with retailers – If you have an established account with a retailer, do not store your payment information with them. In the case of an account compromise, stored payment information may allow a criminal to make purchases using your financial information.
Be Wary of Fraudulent Emails and Advertisements
Look out for suspicious or unexpected emails – A common tactic of cybercriminals year round is to send fraudulent emails seeking to get you to click a link or open an attachment. When it comes to this time of year, they may make an email look like it contains tracking information for a shipment or a promotion for a store. The link or attachment might download malware or try to get you to enter your user credentials in a convincing, yet fraudulent login screen, so they can steal your password. Always avoid clicking direct links in emails, and if you receive an email with a tracking number in it, head to the shipping carrier’s website in your browser and copy and paste the tracking number itself into the site.
Avoid clicking advertisements or pop-up windows of any kind – Advertisements embedded in websites and pop-ups have been known to be compromised by cybercriminals to distribute malware. It is best to avoid clicking them altogether. To close pop-ups, press Control + F4 on a Windows computer and Command + W on a Mac.

Internet Devices & Safe Online Banking
Online banking and remote access to financial accounts is part of daily life now — with connections through internet devices such as smartphones, laptops, readers, tablets or desktops — account information is a click away.
These same devices are used to connect to many other things; like baby monitors, TVs, healthcare data, doorbell cameras, news & information, refrigerators and other household items. And, frequently they are interconnected by a home network that shares all this information and allows internet access.
Without proper security for each device, your personal information is at risk.
➤ Secure All Your Internet Devices
There are several software security packages that offer protection for all your interconnected internet devices including your wireless router. Here are the first steps that are essential to an integrated approach to secure your internet devices.
Passcodes and Passwords:
Internet device suppliers allow you to reset passcodes or passwords. The strongest passwords use a combination of letters (upper and lower case), numbers and symbols and should be at least 10 characters in length to provide the best protection. Importantly, each of your devices requires a separate password — that way if one device is lost, stolen or compromised then not all are affected.
KEY POINT – Never allow your passwords to be remembered by your browser software!
Security Software:
Purchase and install software that detects, prevents and removes all viruses, malware or spyware found on your internet devices. Many manufacturers offer an entire suite of anti-virus security software to protect all your devices. Just remember that different internet devices have different operating systems — one security solution may not protect all your devices.
KEY POINT – Each device requires specific security software protection!
Software Updates:
Manufacturers of internet devices update their software constantly to provide faster service and more secure products. Some of these software updates provide a needed fix for security weaknesses — so sign up with the software manufacturer to receive any updates automatically and install them on a regular basis.
KEY POINT – Software updates provide the best defense against online threats!
Wireless Networks:
Your home network connects to the internet using a router that comes with a default user ID and a pre-set password from the manufacturer. Reset the manufacturer settings for both immediately. The router ID renamed by you and a strong password are essential protections for a home router. Choose the highest level of security available for your router and activate it. Also, enable the preinstalled firewall protection hardware for added safety.
KEY POINT – The router serves as the pathway to the internet for all your devices!
➤ Device Use and Best Practices
Security experts have developed best practices for everyone to follow when using any internet device.
- Wi-Fi hotspots that are public and shared by many users are not secure.
- Always log off by following the financial institution’s secured area exit procedures.
- Back up your data regularly to your personal cloud storage account or external hard-drive.
- All your internet devices should auto lock with a short time period.
- When not in use shutdown or turn off your devices.
- Enable each device to have your data erased or wiped remotely.
➤ More Connections and More Things Are Coming
The ability to conduct safe online banking, purchase things and remotely access, monitor and control home appliances through internet devices offers great convenience for everyone.
In the coming years experts predict rapid growth in the number of interconnected things — doubling by 2020. Make internet device security your number one priority!

Cybersecurity Guide for Businesses
Protect Computers and Networks
Install security and antivirus software that protects against malware, or malicious software, which can access a computer system without the owner’s consent for a variety of uses, including theft of information. Also, use a firewall program to prevent unauthorized access. Protection options vary, so find one that is right for the size and complexity of your business. Update the software, as appropriate, to keep it current. For example, set antivirus software to run a scan after each update. If you use a wireless (Wi-Fi) network, make sure it is secure and encrypted. Protect access to the router by using strong passwords.
Require Strong Authentication
Ensure that employees and other users connecting to your network use strong user IDs and passwords for computers, mobile devices, and online accounts by using combinations of upper- and lower-case letters, numbers, and symbols that are hard to guess and changed regularly. Consider implementing multifactor authentication that requires additional information beyond a password to gain access. Check with vendors that handle sensitive data to see if they offer multifactor authentication to access systems or accounts.
Control Access to Data
Control access to data and computers and create user accounts for each employee. Take measures to limit access or use of business computers to authorized individuals. Lock up laptops when not in use as they can be easily stolen or lost. Require each employee to have a separate user account and prohibit employees from sharing accounts. Only give employees access to the specific data systems they need to do their jobs, and don’t let them install software without permission. Also, make sure that only employees who need administrative privileges, such as IT staff and key personnel, have them and regularly review their ongoing need for access.
Teach Employees the Basics
Establish security practices and policies for employees, such as appropriate Internet usage guidelines, and set expectations and consequences for policy violations. Establish a top-down corporate culture that stresses the importance of strong cybersecurity, especially when it comes to handling and protecting customer information and other vital data. Ensure that all employees know how to identify and report potential security incidents.
Train Employees to be Careful Where They Connect to the Internet
Train employees to be careful where and how they connect to the Internet. Employees and third parties should only connect to your network using a trusted and secure connection. Public computers, such as at an Internet café, hotel business center, or public library, may not be secure. Also, your employees shouldn’t connect to your business’s network if they are unsure about the wireless connection they are using, as is the case with many free Wi-Fi networks at public “hotspots.” It can be relatively easy for cyber criminals to intercept the Internet traffic in these locations.
Train Employees About the Dangers of Suspicious E-mails
Employees need to be suspicious of unsolicited e-mails asking them to click on a link, open an attachment, or provide account information. It’s easy for cyber criminals to copy a reputable company’s or organization’s logo into a phishing e-mail. By complying with what appears to be a simple request, your employees may be installing malware on your network. The safest strategy is to ignore unsolicited requests, no matter how legitimate they appear.
Patch Software in a Timely Manner
Software vendors regularly provide patches or updates to their products to correct security flaws and improve functionality. A good practice is to download and install these software updates as soon as they are available. It may be most efficient to configure software to install such updates automatically.
Make Backup Copies of Important Systems and Data
Regularly backup the data from computers used by your business. Remember to apply the same security measures, such as encryption, to your backup data that you would apply to the original. In addition to automated backups, regularly backup sensitive business data to a storage device at a secondary location that is secure.
Don't Forget about Tablets and Smartphones
Mobile devices can be a source of security challenges, especially if they hold confidential information or can access your business’s network. If your employees connect their devices to the business’s network, require them to password protect their devices, encrypt their data, and install security apps to prevent criminals from accessing the device while it is connected to public networks. Be sure to develop and enforce reporting procedures for lost or stolen equipment.
Watch Out for Fraudulent Transactions and Bills
Scams can range from payments with a worthless check or a fake credit or debit card to fraudulent returns of merchandise. Be sure you have insurance to protect against risks. Additionally, ensure that you report any irregularities immediately.

Cybersecurity Guide for Customers
Protect Your Computer
Install software that protects against malware, or malicious software, which can access a computer system without your consent to steal passwords or account numbers. Also, use a firewall program to prevent unauthorized access to your PC. While protection options vary, make sure the settings allow for automatic updates.
Security when Logging into Financial Accounts
Use the strongest authentication offered, especially for high-risk transactions. Use passwords that are difficult to guess and keep them secret. Create “strong” user IDs and passwords for your computers, mobile devices, and online accounts by using combinations of upper- and lower-case letters, numbers, and symbols that are hard to guess and then change them regularly. Although using the same password or PIN for several accounts can be tempting, doing so means a criminal who obtains one password or PIN can log in to other accounts.
Understand Internet Safety Features
You can have greater confidence that a website is authentic and that it encrypts (scrambles) your information during transmission if the web address starts with “https://.” Also, ensure that you are logged out of financial accounts when you complete your transactions or walk away from the computer. To learn about additional safety steps, review your web browser’s user instructions.
Be Suspicious of Unsolicited E-mails
Be suspicious of unsolicited e-mails asking you to click on a link, download an attachment, or provide account information. It’s easy for cyber criminals to copy the logo of a reputable company or organization into a phishing email. When responding to a simple request, you may be installing malware. Your safest strategy is to ignore unsolicited requests, no matter how legitimate or enticing they appear.
Be Careful Where You Connect to the Internet
Only access the Internet for banking or for other activities that involve personal information using your own laptop or mobile device through a known, trusted, and secure connection. A public computer, such as at a hotel business center or public library, and free Wi-Fi networks are not necessarily secure. It can be relatively easy for cyber criminals to intercept the Internet traffic in these locations.
Be Careful When Using Social Networking Sites
Cyber criminals use social networking sites to gather details about individuals, such as their place or date of birth, a pet’s name, their mother’s maiden name, and other information that can help them figure out passwords — or how to reset them. Don’t share your ‘page’ or access to your information with anyone you don’t know and trust. Cyber criminals may pretend to be your ‘friend’ to convince you to send money or divulge personal information.
