# Devices, updates and backups: holding your hardware

URL : https://skillrung.com/en/courses/cybersecurity/updates-and-backups
Topic: Cybersecurity · Duration: 20-30 min · Updated on 2026-09-15

## In brief

A security update fixes a flaw that has become public, and automated tools look for it within hours: putting it off means leaving open a door everyone knows about. A backup left permanently connected is encrypted along with everything else during an attack: only a copy unplugged after use protects you. And a backup that has never been restored remains a hypothesis rather than a protection, which is why the restore is tested on an ordinary day.

## Programme

- 1. Why hardware gives way at the worst moment : Place what actually protects a workstation, and what changes nothing
- 2. Devices, updates and backups : Keep your devices up to date and have a backup you can actually restore
- 3. Your action plan : Leave with three habits you can apply to your hardware

1 content sections, each with its quiz. Three level quizzes: Beginner, Intermediate, Expert.

## Free preview (first 4 slides)

### 1. « Remind me tomorrow »

It is the most expensive sentence of the working day. An update put off, a backup nobody ever tried to restore, an external drive left plugged in: three tiny decisions, taken to save two minutes, and they decide what will be left after an attack on your structure.

### 2. What you will be able to do by the end

- Install an update without putting it off
- Tell a backup that protects from one that reassures
- Test a restore in a few minutes

### 3. What decides how much is left

Four things, all checkable without an IT department.
- Updates installed as soon as they are offered
- A backup unplugged after use, kept somewhere else
- A restore already tested, with its date written down
- A device encrypted as soon as it leaves the premises

### 4. Where do you stand?

One question to place your reflexes, with no score and no judgement. Answer before you carry on.

## Frequently asked questions

### Do I need technical knowledge to take this course?

No. Everything is explained through everyday actions: reading a message, choosing a password, plugging in a drive, calling the right person. No command line, no setting reserved for an IT department. The examples adapt to the job you indicate.

### My organisation is very small: am I really a target?

Yes. The vast majority of attacks target no one in particular: they cast a wide net and exploit whatever opens. A small organisation is often more exposed, for lack of an IT department and a verified backup.

### How does this course fit into the theme?

It is one step of the Cybersecurity theme. Each course is short and self-contained; the theme exam measures your level across all of them and issues a personal certificate.
