  4. SQL injection
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

SQL injection is a type of cyberattack that targets databases, which is not typically a concern for astronomical data. The other options, phishing, malware, and DDoS, are all common threats to astronomical data.

Multiple choice

Which of the following is NOT a best practice for securing astronomical data?

  1. Implementing strong access controls.

  2. Regularly updating security patches.

  3. Using strong encryption algorithms.

  4. Backing up data regularly.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

While backing up data regularly is important for data recovery, it is not a security measure. The other options, implementing strong access controls, regularly updating security patches, and using strong encryption algorithms, are all essential for securing astronomical data.
