Online activity tracking continues to grow, which means tech companies — and cybercriminals — have more opportunities to access your data. Whether it’s social media platforms, search engines, or internet service providers, the more information they collect, the more they can use it.
Ever wonder why you start seeing dog toy ads right after searching for puppy training tips? That’s often because your online activity was shared across companies and used for targeted advertising.
The bottom line is, your data is valuable. Tech companies use it to drive revenue, and third parties buy it to better understand and reach specific audiences.
How can I protect my data?
In recognition of Cybersecurity Awareness Month, here are six ways to help safeguard your information:
1. Limit personal details on social media.
Avoid sharing sensitive information such as your email address, birthdate, and phone number on public profiles. The more personal information you post online, the easier it can be for someone to misuse it.
2. Be cautious with your Social Security number.
Only share your Social Security number — even the last four digits — when absolutely necessary. Trusted entities may include your bank, a credit bureau, employers conducting background checks, or organizations required to report to the Internal Revenue Service.
3. Watch for phishing attempts.
Cybercriminals use all kinds of tricks to get you to reveal personal or financial information. Be skeptical of any message that asks for account details or creates a false sense of urgency designed to rush your response.
4. Secure your devices.
Set your phone, laptop, or desktop to require a password or passcode to unlock. Devices are often stolen not just for resale, but for the sensitive data they contain. Also, make sure anti-malware software is installed and up to date.
5. Turn on multifactor authentication.
Multifactor authentication is a standard security feature for many online accounts — including myCalPERS. It adds an extra layer of protection by requiring a verification code sent by text or email. Even if someone steals your password, they still won’t be able to get into your account without that code.
6. Choose security questions carefully.
Common questions like “What is your mother’s maiden name?” or “In what city were you born?” may seem secure, but the answers are often easy to find online. Choose questions only you would know — or better yet, use a made-up answer you’ll remember.
CalPERS is committed to keeping your data private and secure through sophisticated cybersecurity systems and industry best practices. For more information about the data we collect, how we collect it, and how it’s used, visit our Privacy Policy webpage.
