My name is Silvia and I am a security/privacy researcher
I am a Ph.D. Candidate at UPC - Barcelona
I am currently working @ torproject.org
I am here to talk about cybersecurity in practical terms.
What is cybersecurity?
Cybersecurity is the protection of computer systems.
A computer system can be anything from your watch to your bank account.
Personal data protection is actually personal safety.
What does this mean?
- Part of our lives are lived online
In 2011, the amount of digital information created and replicated globally exceeded 1.8 zettabytes (1.8 trillion gigabytes) *.
- “meta-data” is collected and stored by public and private organisations about our actions, both online and offline.
Cybersecurity is as ordinary as the weather
Attacks are common
What this attack demonstrates is that the economics of the IoT mean that it will remain insecure unless government steps in to fix the problem. This is a market failure that can't get fixed on its own.
- Computer systems are complex.
- It is difficult to know which parties are trustworthy.
- What if things change?
Things can always change
The internet activity of everyone in Britain will have to be stored for a year by service providers, under new surveillance law plans.
State Simple Objectives
- I want to protect myself and the people I communicate with.

I do not want third-parties to know where I am.
- Disable location sharing on your phone.
- Disable or delete apps that share location.
- If possible do not bring a mobile phone.
I do not want third-parties to know what I do.
- Do not share public updates on social media.
- Do not enable location sharing.
- If possible do not bring a phone.
I do not want third-parties to know what I am interested in
- Avoid public updates on social media.
