Session held on Cyber Security, and CTFs, where participants can get more idea about the event.

1. CYBERSECURITY
CTF

2. CYBER SECURITY
Cyber Security is the protection of computer systems and networks from attack by
malicious actors that may result in unauthorized information disclosure, theft of, or
damage to hardware, software, or data, as well as from the disruption or misdirection of
the services they provide
● Network Security
● Application Security
● Information Security

3. Vulnerabilities
Overcoming
Vulnerabilities

4. Vulnerabilities and Attacks
1. BackDoor
2. Phishing
3. Reverse Engineering
4. Spoofing
5. Tampering
6. Malware (Malicious Software)

5. CTF
Capture the Flag (CTF) in computer
security is an exercise in which
"flags" are secretly hidden in
purposefully-vulnerable programs
or websites. It can either be for
competitive or educational
purposes.

6. Capture The Flag
There are 3 Common Types of CTF’s
1. Jeopardy-style CTFs Couple of questions in range of
categories. Ex: Web, Forensics, Crypto, Binary…
2. Attack defense: It’s a interesting Kind of competition, every
team have a host, with vulnerable services, Organizers connects
participants and wargame starts, you should protect your own
services for defense points and hack opponents for attack points.
3. Mixed: A combination of both
Is it weird? : fXRwcF9uaV9nYWxmX2VodF9kbnVvZl91b3lfb2dub2N7c2tjYWhyZXRuaXc=

7. Let’s Solve a Flag:
- Ever Saw this?

8. Cryptography

Cryptography is a method of protecting information
and communications through the use of codes, so
that only those for whom the information is intended
can read and process it.

9. It’s ok you found a flag in text (encrypted)
What about in a image?

10. Steganography
Steganography is the art of hiding messages inside an image.
So another task
Can you find the flag?
In your mobile / Laptop 😈😈😈`

11. Reverse Engineering
Bottom to Top.
