This document provides an overview of cyber security topics including wireless networks, types of attacks, security goals, computer forensics, security threats, examples of cyber crimes, ransomware attacks, strong passwords, malicious code, programming bugs, cryptography, digital signatures, security procedures, guidelines, security laws, intellectual property rights, and security audits. It discusses key concepts such as confidentiality, integrity, and availability as goals for security and describes common cyber crimes like identity theft, hacking, and credit card fraud.

1. Cyber Security

2. .

3. Topology & Types of Networks

4. Wireless Networks:
A wireless network is any type
of computer network that
uses wireless data connections for
connecting network nodes.

5. Internet

6. Types of Attacks:
* Passive Attack *Active Attack
* Distributed Attack * Insider Attack
* Close-in Attack * Phishing Attack
* Hijack Attack *Spoof Attack
* Exploit Attack *Password Attack
* Buffer Overflow Attack

7. Goals for Security:
Confidentiality
Integrity
Availability
E-commerce Security

9. Computer Forensics:
Computer forensics is the
application of investigation and analysis
techniques to gather and preserve evidence from
a particular computing device in a way that is
suitable for presentation in a court of law.

10. Overview of Security threats

11. Examples of Cyber Crime
1. Identity Theft
2. Transaction fraud
3. Fake calls
4. Piracy
5. Hacking social sites

12. 6. Hacking into personal accounts
7. Hacking into work databases
8. Schemes/scams based on fake
websites
9. Various credit-related thefts
10. Breaking into competitor
databases

13. Ransomeware Attack
Ransomware is a type of
malicious software that threatens
to publish the victim's data or
perpetually block access to it
unless a ransom is paid. While
some simple ransomware may
lock the system in a way which is
not difficult for a knowledgeable
person to reverse, more advanced
malware uses a technique called
cryptoviral extortion.

14. Strong Passwords & Password
Cracking

15. Malicious Code:
Malicious code is code causing
damage to a computer or system. It is
code not easily or solely controlled
through the use of anti-virus tools.
Malicious code can either activate itself
or be like a virus requiring a user to
perform an action, such as clicking on
something or opening an email
attachment.

17. Programming Bugs:
In computer technology, a bug is a
coding error in a computer program. The
process of finding bugs before program users
do is called debugging.

18. C

21. Cryptography/Encryption:

22. Digital Signatures

25. Security Procedures:
Handling copyright infringement notifications - The steps
Information Security will take if informed of a copyright
infringement that has happened via the LSE network.
Log duration - How long IMT will keep logs that have been
generated.
Non-standard user account expiries - The maximum duration
non-standard LSE user accounts will exist and at what point
extensions will need to be requested.
Virus outbreaks on campus public area workstations - What
we will do if we discover there is a virus outbreak on an LSE
machine in the library, or in a computer room.

cloud storage
