Explanation:

For the first question, keeping software and operating systems updated is a common cybersecurity best - practice to patch vulnerabilities. For the second question, "salting" in password security refers to adding a random string (not just numbers or a personal code in the way described) to passwords before hashing, but if we assume a more basic understanding, adding a form of extra data (which could be mis - represented as a personal code in a simple context). For the third question, Rachel Tobac is known for focusing on the human element in cybersecurity, such as social engineering.

Answer:

1. Keep all devices and software constantly up to date
2. Adding a personal code to stored passwords
3. Human element of security
