Government employees nationwide are moving to at-home work locations as social distancing in response to COVID-19 (the “coronavirus”) increases. The ever-present cyber threats that concern governments, however, don’t disappear when employees go home.
Public sector staff can follow these top tips to mitigate risk and protect both public and personal networks and information.
1. Understand you are a target.
In this new age of working from home, phishing attacks are on the rise. Be especially cautious of emails that take advantage of COVID-19 news and purport to provide coronavirus alerts, request donations, or request urgent action.
As we move more and more to email communication, increased vigilance is necessary. Just because the “From” address contains your boss’s name, for example, doesn’t make it real. Emails that mimic an in-house address are known as Business Email Compromise (BEC) scams. They often include instructions for redirecting funds.
2. Follow your employer’s security practices.
Security rules still apply, regardless of your location, especially when you’re on a work-issued laptop. Just as in the office, do not use your work laptop for personal web surfing, email, chats, videos, or podcasting. In other words, only do work. Similarly, do not allow your family members, roommates, or others to use your work laptop. Use the VPN connection provided by your office for all access to your department’s network, resources, and the internet, if necessary. If your administrator issues patching orders, verify their authenticity and follow them to keep pace with new vulnerabilities.
The use of personal laptops to access an organization’s network is a significant security risk. Only use personal equipment if you have permission and be sure to use a secure VPN connection or virtual desktop. If you must use a personal laptop, make sure it is current with security patches and anti-virus software, and encrypt the hard drive. (Your network administrator can help you do this.) As with an office laptop, only do work at work. Minimize personal web surfing and email to create the most secure environment.
Whether your laptop is work-issued or personal, never leave it unattended in public or visible in a car. If you must travel with your laptop, store it in the trunk while you’re out of your car. And, just like we routinely shred sensitive information on paper, no sensitive files should be stored on any laptop unless your agency’s policy permits it. Do not transfer sensitive information to a USB drive or cloud service unless directed to do so by your employer and purge sensitive information from your laptop once it is no longer needed.
3. Secure your home network.
Handling network, computer, and IT issues will be new to most employees working remotely for the first time. To create the most secure environment, turn on encryption (WPA2 or WPA3) and make sure your router is updated with the most current security patches. Some routers update patches automatically. Reach out to the person who installed your home network to check. That person should also tell you if they have changed the default administrator password on your router.
4. Follow basic cybersecurity hygiene.
We are all washing our hands and following hygiene protocol with rigor. The same should hold true for your digital health. Basic cybersecurity hygiene revolves around passwords. Use strong passwords that follow your company’s policy and consider using passphrases over 15 characters instead of the usual eight. For example, use: IwishMyCarWasa69BabyBlueDuneBuggy instead of: Ah$Y9z&Z.
Using a password manager recommended by your IT department to generate strong passwords takes the guesswork out of it. Visit the National Cyber Awareness System for more password tips. Finally, enable multifunction authentication if possible.
