2. Overview
* Computer Privacy
* Hacking and Ethical Hacking
* Computer Crimes and Forensic Investigations

3. Computer Privacy
* It is about your/ your computer's identity.
* It is about your private and confidential data.
* The security of your data is important when you
share your data over the network; hence you need
your privacy been protected [1].
* Data privacy: Basically you need to decide what

4. Computer Privacy
* It is about your/ your computer's identity.
* It is about your private and confidential data.
* The security of your data is important when you
share your data over the network; hence you need
your privacy been protected [1].
* Data privacy: Basically you need to decide what
data to be shared and what not! [2]

5. Hacking
*Accessing data/computer infrastructure without
the owner's concession.
*Hacking is illegal but it needs a lot of talent in
programming, scripting, networking knowledge
together with Information Security knowledge.
*Good hackers and good programmers and
analysts.

6. Ethical Hacking
* Hacking a computer system/ network/enterprise
solution with proper authority from the
management of the particular system/organization
* Follow the same steps of a hacker to identify the
security loop wholes.

7. Ethical Hacking (contd)
* Steps involved [3]:
1. Reconnaissance
2. Scanning
3. Access and Escalation
4. Ex-filtration
5. Sustainment
6. Assault
7. Obfuscation

8. BLACK, WHITE & GRAY HAT
Hacking?
* Black hat: What we know as hacking; an attacker illegally
accesses a system – a crime
* White hat: Ethical; has permission to do so; typically a
paid job
*Gray hat: Neither black nor white :) Has no permission but
no harm. Points out the issues after hacking!

9. Computer Crimes
* Same as hacking but it is more than hacking!
* Illegally access information of an organization or a person
and do harmful things.
Examples [4]:
* Cyber terror
* DoS
* Frauds
* Espionage

10. Forensic Investigations
* Investigating how a cyber crime happened
* Cyber Security Experts handling these
* Need to know all aspects of information and network
security.

15. Effective Search in Google
Quotated from one of my paper articles and also the initial
knowledge I got about these, from my CEH training with CICRA.
1. link:
Think that you want to find webpages that have link to a
particular web page then you can the keyword link:
Example: If I type link:www. tharinduweerasinghe.com in Google
Search Box then Google lists down all the web pages that have
links to the site mentioned in the search.

16. Effective Search (etc)
2. related:
If you need to list down all the web pages that are similar to
the one mentioned in the search box, then you can use the
above operator word.
3. info:
If you need to retrieve some information that Google has
regarding a particular web page then you can use this
keyword or the operator word.

17. Effective Search (etc)
4.site:
If you use site: syntax in your search query and specify a
site that should search your terms then it will list all
occurrences of the search term in that particular site.
Example Search: Tharindu Weerasinghe site:pdn.ac.lk
This will list all places that has my name in the Peradeniya University website
5.intitle:
This will list the documents containing the search term in
the title.
Example Search: Tharindu Weerasinghe
6.inurl:
This will list the documents containing the search term in
the URL (web address).

18. Academic Search
Engines/Databases
* Google Scholar
* WorldCat
* IEEE Xplore
* ACM Digital Library
