Q & A
What was the situation that led to the speaker's daughter Kelly's laptop being seized by the FBI?
-Kelly was reading a free online novel when her laptop screen froze, and an on-screen image appeared to be the FBI, claiming they had breached her laptop and demanding a ransom to regain access.
What advice did the speaker give Kelly after the incident with the FBI?
-The speaker advised Kelly to always be cautious online, scrutinize emails for grammar and language, check URLs for legitimacy, look for secure HTTPS connections, and be aware of the risks of cybercrime.
Why was the speaker's friend Richard's bank account accessed and his savings stolen?
-Richard's cell phone was accessed when he left it unattended at a library, and his bank account password, which was based on his favorite wine 'Merlot', was an easy guess, leading to the theft of his savings.
What is the importance of using a unique username for each account according to the speaker?
-Using a unique username for each account helps to prevent unauthorized access and reduces the risk of a single breach compromising multiple accounts.
What is two-factor authentication and why is it recommended for enhancing security?
-Two-factor authentication is a two-step verification process that requires a second device for access, making it more difficult for hackers to gain unauthorized access to accounts.
What is the significance of the HTTPS protocol in ensuring online security?
-HTTPS indicates a secure and encrypted connection, meaning that the content cannot be read by hackers, unlike HTTP which is not encrypted and can be easily intercepted.
Why is it crucial to update software and applications regularly?
-Regular updates ensure that security vulnerabilities are patched, protecting against attacks that exploit outdated software.
What is the role of a passphrase in cybersecurity?
-A passphrase is a strong, less predictable password that is typically composed of multiple random words or characters, making it harder for attackers to guess or crack.
Why is it advised to scrutinize all email and text messages?
-Scrutinizing messages helps to identify potential phishing attempts or scams, which often come in the form of seemingly legitimate but malicious emails or texts.
What is the speaker's analogy for the importance of cybersecurity?
-The speaker compares cybersecurity to locking the door to your house or car, suggesting that while it may not stop a determined attacker, it makes the process more difficult and may deter them from targeting you.
What is the speaker's final advice on being the gatekeeper of one's technology and personal information?
-The speaker advises to be risk-aware and cyber-aware every day, to update software regularly, use strong passphrases, employ two-factor authentication, scrutinize messages, and use antivirus software to protect personal information and data.

Transcripts
foreign
it's a Bittersweet moment when your
child starts growing up
you're so proud of their various
accomplishments
and all of a sudden you realize that you
failed them
I failed my oldest daughter Kelly
I told her almost every day to be
cautious when she's using the internet
and what to look out for while she's
online
I regret to tell you that she did not
listen to me
last year I got a call from Kelly who
informed me that the FBI had her laptop
can you imagine that
I'm a cyber security expert and my own
daughter did not practice cyber safety
Kelly was in her apartment reading a
free online novel something that she
enjoyed
when suddenly her laptop screen froze
it appeared to Kelly that the FBI
breached her laptop
she stopped like a deer in the
headlights while trying to gather
herself she was frightened out of her
wits and I could hear a River of Tears
flowing down her face
the on-screen image showed the FBI seal
a picture of Kelly as she sat reading
the online novel
and they demand that she immediately
paid three hundred dollars to regain
access
how scary is that the message looked
official think about it you get a
message like that from the FBI
and what occurred with that point was
Kelly paid the ransom with a prepaid
card as she was as she was required to
do
then all of a sudden she gave me a call
and we talked about it about what she
should do and how she should prepare
herself when she's online and at that
particular point I gave Kelly three
pieces of advice one always be cautious
when you're on the internet you have to
look for fake emails look at the grammar
look at the language there's always
someone trying to trick you you can do
several things you can take the mouse
and scroll it over their URL is it a
legitimate site or not a legitimate site
that's what being cautious is really all
about every single time whether you're
on your phone your tablet your computer
your eye your Apple I watch anytime you
touch the internet you must be cautious
every single time
third I told her well second I told her
to look out at your browser the https
with the little clock tells you that it
is secure and what insecurity means is
that it's encrypted which means that
someone hacks it they can't read the
content whereas HTTP no s it is on it's
not encrypted it's plain text and any
hacker can read it at any particular
tile and so therefore it's really
important for you to be cyber safe
for example in 2021 over 50 million
Health Care records were breached
and I guess you may ask what do hackers
want
hackers want every single thing they
want your confidential information your
metadata your date of birth your
internet traffic your gaming information
they want everything identity theft is a
major cyber crime for example
if I get your credit card
your email address with a weak password
and guess what I buy a boat thank you
very much
the famous bank robber Willie's son he
was asked why do you rob banks and he
said that's where the money is
hackers hack Because the Internet is
where the money is
data is stolen information data is
stolen and sold on the internet dark web
all the time and so that's where your
information is going to end up so I
would say this any of us can be hacked
at any given time at any given time so
therefore you must be cautious I have a
friend Richard who spends a lot of his
time at his local library researching
his favorite his wine making habit so
one particular day he left his
belongings on a study table uh didn't
think anything of it and when he came
back a stranger was looking at his cell
phone and you know he didn't think
anything of that either but later on he
left the library tried to make a
purchase and it was declined
he checked his bank account and realized
that it was accessed I mean he had a
strange painful look on his face and he
said I made a huge mistake
in most situations human error is the
weakest link in the cyber security chain
more than that Richard's cell phone was
accessed and his Savings of two hundred
thousand dollars were gone
ironically though his bank account
password was his favorite wine merlot an
easy guess based on his Hobby
and what occurs with your password is
this at least 60 percent of people use
their name or date of birth as their
password and that's something that you
definitely should not do for example
your password should never be reused and
it should never be shared that's like
opening your digital door to a problem
and more importantly today software is
designed to guess your password so
you're pretty much playing against a
computer and this is what's very
important and so Richard I advise him to
do several things every single time one
use your auto lock feature that's on
every cell phone and don't leave your
cell phone unintended basically anytime
more important to that use a username a
unique username every single time you
have an account regardless of what that
account is your banking your auto your
home loan a different username with
every account then use an encrypted
passphrase a strong encrypted passphrase
with your devices all the time and more
importantly use two-factor
authentication now two-factor
authentication is a two-step process
that pretty much gives you more security
uh with any of your devices which means
that you can't get access without a
second device and so once again that
limits the idea of having hackers take
your stuff and that's very important
because cyber security is really the
process of protecting your sensitive
data and that's something you have to do
as a gatekeeper of your information
whether it's your personal information
the school information the Hospital's
information your insurance information
your data exists in a database somewhere
and you have to ask yourself how secure
is my information because once again
hackers are looking for it all the time
and so therefore it's very important I
would say this that Kelly and Richard
are like many of you you don't need to
be a cyber security expert to be cyber
safe but you knew but you do need to be
cyber aware and being cyber aware is
that you're going to take the time to be
cautious you're going to take the time
not to be so click quick to click and
that's very important so I'll leave you
with these several things that you need
to think about almost every single time
you touch technology anywhere it may
exist you must make sure that your
software and applications are updated
regularly you must make sure you have a
strong passphrase and a passphrase is
simply less predictable if it's usually
four or five random words uh 18 16
characters or something like that it's
very important that you have a unique
passphrase to use and then you want to
make sure you use two-factor
authentication once again you don't want
to make it so easy for anyone to gain
access to your devices then I would
encourage you to scrutinize all email
and text messages that's really critical
and also finally with that make sure
you're using a anti-virus software there
are plenty of them out there that you
should be using as well so more
important than anything else as I said
it's important for you to be the
gatekeeper of your technology when it
comes to your personal information your
data your family status because as I
said cyber security and cyber crime is a
global phenomenon you're you're battling
against bad guys who simply job it is to
get what you have and so you have to be
risk aware and cyberware every single
day now and pretty much forever more so
once again I would tell you that cyber
security is like locking the door to
your house or your car it may not stop
the bad guy but if you make the uh make
it more difficult and more secure he may
go on to a easier Target so therefore
you must be you must be secure you must
stop think before you click
lock your digital door
