3. ONLINE VERSION OF PRESENTATION
IN SCHOOL
This is an online version of a presentation I give in
school
The slide numbers therefore begin slightly higher in
order to synchronise with the presentation I give.

4. OUR DIGITAL WORLD
What is our digital
world?
Issues teenagers face
How do we respond to
those issues?
Further support
available

5. So what is our digital world
like?

7. Are we living in a surveillance
era?

8. The internet isn’t a reflection
of a teenager’s life
It is their real life

9. Families

10. The Internet is a positive
system

11. Creation

12. Connection

13. Understanding the world

14. What issues do teenagers
face today?

15. There is NO
privacy on the internet

16. Your information will at some
point be read by a human or
computer and a decision
made

17. Personal safety on the internet
can be compromised through
careless words or actions

18. Cyber-bullies can leave you
feeling un-safe in your own
home

19. Malicious communication
through texts, tweets and now
apps can impact youngsters

20. Careless actions can have an
impact on financial security
such as theft of devices or
access to accounts like iTunes

21. The internet IS real life

22. How do we deal with these
issues and in turn educate our
children?

30. @ home ?

31. SECURING YOUR COMPUTER AND
ONLINE LIFE
1. Passwords
2. Security Software
3. Home internet filtering

32. PASSWORDS
Having to remember Ty!89?ghjK for even one site is
hard enough
Use a few complex passwords
- Which are memorable but contain sufficient variation
- !WldWlk500Miles
Chain a few words together
-antelope50beach85south?
Wiki article on password strength

33. SECURITY SOFTWARE
Have decent well-reviewed security software installed
- Norton, McAfee and Kaspersky for PC or Sophos for
Mac
AVG free?
- Would you use a free car?
Pay the annual fee
Security software reviews

34. HOME-BASED INTERNET FILTERING
USING OPENDNS
OpenDNS provides family home filtering using DNS
servers
DNS servers are the ‘address books’ of the Internet
At a basic level filter adult sites, proxy servers, phising
sites and some malware
LINKS ON PAGE

35. TWO-FACTOR AUTHENTICATION
One-factor authentication is the use of a password
(something you know)
2FA is the use of something you know and something
you have (a phone)
When logging in to certain services you are sent a one-
time only unique code to login
LINKS ON PAGE

36. TWO-FACTOR AUTHENTICATION
Benefit is added security
However don’t lose your phone!
Popular services using 2FA include:
- Google, Facebook, Twitter, Apple, Dropbox, Paypal
and a few more

38. HOW TO USE 2FA EFFECTIVELY
Set it up on at least one major service such as Google
Mail
Use your Gmail account to setup other accounts such
as Facebook, Amazon etc

39. LOGIN NOTIFICATIONS
Sites like Facebook use these
They show you if someone attempts to login to your
account from another location
LINKS ON PAGE

40. 3RD-PARTY APPS AND SOCIAL
NETWORKS
In our connected world services like Facebook, Twitter
etc allow access to 3rd party apps which can use some
of their features
For example my Facebook account allows my tumblr
blog to create a link on Facebook everytime I post to
tumblr.
Certain apps can compromise your account if they post
messages to your followers or worse

41. MANAGING 3RD-PARTY APPS
Check your app settings on each of your social
networks
For example in Facebook use account settings to
manage which apps you have allowed
Remove ones you are unsure about

42. METADATA
Metadata is data about data
Eg if I take a photo (data) the data about it would
include
Timestamp
Camera type
Photo settings and depending on the type of device
Co-ordinates derived from GPS
LINKS ON PAGE

43. GEOTAGGING
Geotagging is the process of attaching a GPS location
to a piece of digital content
- Photo
- Tweet
- Foursquare checkin
It has benefits but also negatives – daughter posting a
picture of herself at home online with photo geotagged?

44. DEALING WITH GEOTAGGING
Check the settings on your child’s smartphone
- An iPhone for example can turn location settings off
Apps such as Twitter also have flags for turning on/off
geotagging

45. SHORT LINKS ON TWITTER
Due to the length of twitter posts longer email
addresses are often shortened such as
http://community.computingatschool.org.uk/
Is shortened to …
http://bit.ly/Omnauf
Use http://longurl.org to extend the address if you are
unsure as to where it might lead you
LINKS ON PAGE

46. MANAGING SMARTPHONES AND
TABLETS
For very young children use ‘Guided Access’ for iPads
Use gift vouchers to manage the purchase of apps
Use the restrictions panel on an iPhone or iPad to
manage things like in-app purchases
Manage the iTunes password yourself – this will control
the apps downloaded
LINKS ON PAGE

47. LOSING AN EXPENSIVE DEVICE
For Apple devices use iCloud and Find my iPhone to
locate missing devices, ping them or lock them down
Similar services can be purchased for Android devices
LINKS ON PAGE

48. MESSAGING ON SMARTDEVICES
Parents can’t do surveillance like the NSA can!
Skype is reasonably popular
More popular are over-the-top messaging apps such as
Whats-app or iMessage – text message services
Recently popular is Snapchat

49. DEALING WITH INAPPROPRIATE
COMMUNICATIONS
Gather evidence!
If you are aware of the apps your children are using
familiarise yourself with how to collect evidence
Take that evidence to organisations like CEOP

50. SUMMARY OF SUGGESTIONS
Secure Passwords and multiple levels of logins
Use one security suite but a range of extra tools
Discuss with your children and show them you are
knowledgeable as well
Know what agencies can help if something does
happen

51. IN CONCLUSION
Esafety will always be evolving
Keep on top of developments yourself
Increase your trust in your children as they get older

54. Reading requires time and
attention. Reading is a cognitive,
mental, emotional action, and
today it is under pressure from all
this speed of the Internet and the
whole digital world. The biggest
principle of this world is speed,
everything has to do with speed,
that is how it is measured and
that is how it is lived. When you
read a book or a poem or listen to
music, there is a matter of
moderation, of time. This
technology is an assault on time.
