Protecting Student information
Protecting Student information
You may already know that there are several state and national efforts to protect confidential student information. That's critical due to the cyber threats schools and organizations face today.
You may already know that there are several state and national efforts to protect confidential student information. That's critical due to the cyber threats schools and organizations face today.
The Texas Education Agency is working to provide funding for anti-malicious activities. That is, the Texas Legislature approved funding to provide cybersecurity resources to schools through the K-12 Cybersecurity Initiative.
Secure Our World. Learn how to protect your family. K-12 Cybersecurity resources are also available.
Texas School Safety Center. This website offers cyberthreat workshops via Zoom. Sessions on cyber threats and school safety are available to school district personnel.
SchoolSafety.gov. This federal government website offers cyber safety considerations for K-12 schools and districts. It highlights resources for stopping phishing and ransomware, as well as other threats.

Google's K-12 Cybersecurity Guide
Google's guide highlights these problems...
100 million phishing attempts blocked by Gmail daily
300,000 unsafe websites identified by Google
46% of ransomware attacks are harder to stop due to sophistication
38% of organizations expect to be targeted (source)
...and offers solutions and suggestions:
Using secure authentication to protect sensitive information
Strong passwords and two-step verification (or multi-factor authentication), passkeys, and password managers
Put in place zero trust principles to restrict access to those who need it
Update and upgrade systems (including Chromebooks)
Rely on real-time alert and monitoring systems for devices on the school network
Protect against inappropriate account logins, file sharing, phishing, malware, and other threats
Provide training to teachers, staff, and students
"Not only have these attacks disrupted school operations, but they also have impacted students, their families, teachers, and administrators.
Sensitive personal information – including, student grades, medical records, documented home issues, behavioral information, and financial information – of students and employees were stolen and publicly disclosed.
Additionally, sensitive information about school security systems was leaked online as a result of these attacks."

Safeguard Your Data
Safeguard Your Data
End-to-end encryption make your messages…unintelligible…to snoops and interlopers. [They] can’t access what you’re saying—and neither can the company that offers the platform. People who once thought they had nothing to hide may realize that era is now over (source).
By taking the time to carefully communicate with staff and students the importance of protecting private data, you can minimize the threat of breaches and unauthorized access (source).
It's not hard to safeguard your data, even when it's in plain sight. You simply need to learn to encrypt files or folders using free software. You can then put those encrypted files/folders in cloud storage, USB external hard drives for backup purposes. It all starts with secure passwords you can remember or save in a password manager.

Multi-Factor Authentication
Multi-Factor Authentication
Multi-factor authentication includes at least two of the following:
Something you have — A physical item you have, such as a cell phone or a card.
Something you know — Something you know, such as a password, PIN, personal information like mother's maiden name, etc.
Something you are — Biometric data, such as fingerprint, retina scan, etc.

Did you know that if data is encrypted and a data breach occurs, you are not obligated to report it? This is the power of data encryption and can potentially spare you and your employer from unnecessary litigation and expense. This is known as an encryption safe harbor.

The concept of “Safe Harbor” refers to specific actions that an individual or an organization can take to show a good-faith effort in complying with the law. This good-faith effort provides a “Safe Harbor” against prosecution under the law (source).

Connect with your email recipient (the person you are writing to). Decide on what file/folder encryption tool you will both be relying on to send protected content. Some options that work well: Secure Space Encryptor (SSE), 7zip, or FileLock. Decide how you are going to verify receipt of the encrypted file attachment.
Send the top secret password you will be encrypting via a secure messaging tool, such as Signal. Avoid sending it via email since your email message is a postcard (anyone can read it) unless it is encrypted. Verify receipt.
Encrypt your file attachment, such as a Word, Excel, or other document using your preferred option (e.g. FileLock, SSE).
In the body of your email message, keep it simple and attach the encrypted file (filename.enc).
Send message to your email recipient, then verify receipt.

Encrypting files with AES-256 can be done with a variety of tools. Here are a few you can use that are free. A few tools include:
7zip for Windows - This is a zip/7zip compression program that combines multiple files into one. Think of it as putting a folder of files into ONE file that is compressed for space and encrypted for security. Other, less bare-bones option include Zipware and/or PeaZIP.
Keka Zip for Macs - This is the same thing as 7zip but for Mac computers.
Paranoia's Secure Space Encryptor (SSE) - Here is (what I think) is the best cross-platform encryption tool available. It works on the most platforms (e.g. Android, Mac, Windows). One of the features is that it can take a folder of files and encrypt them all into ONE file.
FileLock.org - A browser-based solution that works well for Chromebooks. Encrypt individual files via your web browser.

From ransomware to simply human error, it's easy to lose data. That's why it's important to make regular data backups. Most people don't know how, so they tend to rely on cloud storage or nothing.

USB External Drive
One way to avoid that is to get a USB external drive (2 terabytes is plenty. USB external drives last three to five years on average, so you may want to invest in one every three years to backup your data). You can use free tools to automate backups.
