Much of our focus for Cybersecurity Awareness Month is on
how the Navy’s cybersecurity is threatened by nation states, ideologically
motivated hackers, cyber criminals, and malicious insiders. Our cybersecurity
workforce and Cyber Mission Forces battle these cyberspace adversaries every
But just as importance is for each and every one to pay
close attention to your own cyber vulnerabilities, at work and at home. Those
same adversaries mentioned above can target you whether you are at work or on a
personal device outside of work.
Cyber criminals use some of the same tools and techniques as
these bad actors to target anyone who has a personal computer, smart phone or
smart device. They are primarily interested in financial gain but may hack for
other illegal purposes. Regardless, you are the front line that is defending
your personal data and devices from their attacks.
The Department of Homeland Security (DHS) has produced a series of short, information-packed, easy-to-read “tip sheets” for protecting yourself online. These guides are available, but we have reposted tip sheets for protecting yourself on the home front. Topics range from social media cybersecurity to protecting internet-connected sensing devices but there are some common themes repeated below:
- Shake up
your password protocol. According to National Institute for Standards and
Technology guidance, you should consider using the longest password or
passphrase permissible. Get creative and customize your standard password for
different sites, which can prevent cybercriminals from gaining access to these
accounts and protect you in the event of a breach. Use password managers to
generate and remember different, complex passwords for each of your accounts.

your login protection. Enable multi-factor authentication (MFA) to ensure
that the only person who has access to your account is you. Use it for email,
banking, social media, and any other service that requires logging in. If MFA
is an option, enable it by using a trusted mobile device, such as your
smartphone, an authenticator app, or a secure token — a small physical device
that can hook onto your key ring. Read the Multi-Factor Authentication How-to-Guide
for more information.
- Play hard
to get with strangers. Cybercriminals use phishing tactics, hoping to fool
their victims. If you’re unsure who an email is from — even if the details
appear accurate — or if the email looks “phishy,” do not respond and do not
click on any links or attachments found in that email. When available, use the
“junk” or “block” option to no longer receive messages from a particular
click and tell. Limit what information you post on social media — from
personal addresses to where you like to grab coffee. What many people don’t
realize is that these seemingly random details are all criminals need to know
to target you, your loved ones, and your physical belongings — online and in
the physical world. Keep Social Security numbers, account numbers, and
passwords private, as well as specific information about yourself, such as your
full name, address, birthday, and even vacation plans. Disable location
services that allow anyone to see where you are – and where you aren’t – at any
given time. Read the Social Media Cybersecurity Tip Sheet for more information.
- If you
connect, you must protect. Whether it’s your computer, smartphone, game
device, or other network devices, the best defense against viruses and malware
is to update to the latest security software, web browser, and operating
systems. Sign up for automatic updates, if you can, and protect your devices
with antivirus software. Read the Phishing Tip Sheet for more information.
protected while connected. Before you connect to any public wireless
hotspot – like at an airport, hotel, or café – be sure to confirm the name of
the network and exact login procedures with appropriate staff to ensure that
the network is legitimate. If you do use an unsecured public access point,
practice good Internet hygiene by avoiding sensitive activities (e.g., banking)
that require passwords or credit cards. Your personal hotspot is often a safer
alternative to free Wi-Fi. Only use sites that begin with “https://” when
online shopping or banking.
- Keep tabs
on your apps. Most connected appliances, toys, and devices are supported by
a mobile application. Your mobile device could be filled with suspicious apps
running in the background or using default permissions you never realized you
approved — gathering your personal information without your knowledge while
also putting your identity and privacy at risk. Check your app permissions and
use the “rule of least privilege” to delete what you don’t need or no longer
use. Learn to just say “no” to privilege requests that don’t make sense. Only
download apps from trusted vendors and sources.
An additional tip for protecting yourself when accessing
public Wi-Fi is to use virtual private network (VPN) software, which encrypts your
online communications. Anti-virus software companies and other software providers
offer affordable VPN solutions.
By following the advice in this blog and the more detailed
guidance in the DHS tip sheets, you will reduce your chances of: becoming one
of the 60 million Americans affected by identity theft, being held hostage by a
ransomware attack, or having your credit card exploited.
The good cybersecurity habits you learn and apply at home
will also help you protect the Navy from cyber adversaries when you are at work.
