Patch Operating Systems and Applications - HTML5 Transcript/Captions

(This video opens to the Communications Security Establishment logo on a black background. At a breakfast table, a woman drinks a cup of coffee while browsing her emails on her laptop computer. A female narrator begins to speak.)

We use technology and networks to do Government of Canada business every day.

(The woman puts down her cup and consults a notebook as she types.)

But if you’re not properly protecting your networks, they’re vulnerable.

(Raindrops run down a window as the title appears on screen: “Communications Security Establishment - Top 10 IT Security Actions - Patch Operating Systems & Applications.”)

That’s where the Communications Security Establishment comes in. We’re here to give you the support and advice you need. If the forecast is calling for rain, you would

take the time to prepare for the conditions. Readying yourself for the weather is like the ongoing work Government of Canada departments must do to ensure their operating systems and software are patched and protected.

(She walks down a large city sidewalk, firmly holding her umbrella.)

Patch early and patch often. Patch early because every time a software

patch is released, it reveals a vulnerability to everyone.

(Rain pours from grey skies as the woman walks past stores. She pulls out her smartphone from her handbag to find that she has received an email. A holographic visual effect appears next to her phone, the text reads: “System patching will occur tonight.” She puts the phone back in her handbag. Seen from above, she crosses an intersection. She enters a vast glass hall through revolving doors.)

Patch often because cyber threats and vulnerabilities are changing all the time -- just like the weather. …pause….


(Entering an office space, she hangs her soaked umbrella. She takes her coat off and starts to type at her work desk. Other workers can be seen working in their cubicles in the background. A time-lapse sequence shows her working at her desk and interacting with colleagues.)

So it’s a race between patching your systems, and those who want to exploit the vulnerability to access your networks. It’s a race too important to lose.


(A view of the city skyline as the sun sets is shown in a time-lapse. Floor lights of a high-rise begin to shut off one by one. In the office, the woman and her colleagues leave. The floor light turns off but the computer screens remain open. Animated holographic icons appear over each computer. They depict a status bar with the words: “Patching in progress.”)

The majority of cyber incidents detected by CSE were based on known vulnerabilities that

were preventable. So don’t leave your networks exposed.

(The CSE building exterior is shown in its entirety. Multicolored triangles reminiscent of the CSE building’s triangular windows appear to form a motif. Inside it, the words: “Advice Guidance Services” emerge.)

Patching is just one of CSE’s Top 10 IT Security Actions. Protect your networks. Protect Canada’s information.
