Today is the age of computer and internet. More and more people are creating their own websites to market their products and earn more profit from it. Having our own website will definitely help us in getting more customers purchasing our products but at the same time we can also attract hackers to play around with our website. If we have not taken enough care to protect our website from hackers then our business can even come to an end because of these hackers. If we own a website, then we might know the importance of ensuring that our website is safe from viruses and hackers.
After going online most of the website designers think that their work is over. They have delivered what they were paid for and now they will be available for the maintenance of the site only. But sometimes the main problem starts after publishing the website. What if the website they have built suddenly start showing different stuff from what was already present there? What if weird things start appearing on the pages of our website? And most horribly what if the password of our login panel has changed and we are not able to login into our website. This is called hacking, a website hacking. We have to figure out how this happened so we can prevent it from happening again. In this seminar we are going to discuss some of major website hacking techniques and we are also going to discuss how to prevent website from getting vulnerable to different attacks currently use by various hackers.
This presentation describes penetration testing with a Who, What, Where, When, and How approach.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks

Importance of Vulnerability Research.
Vulnerability Research References.
Conclusion.
3. WHY SECURITY ?
• Increasing use of Complex computer
infrastructure.
• Increasing use of Network elements &
applications.
• Decreasing level of skill set.
• Any Security breach in company will affect its
asset & goodwill.
•Any Security breach in government can affect its
operations & reputation.
4. HACKING-DEFINITION
• The Art of exploring various security breaches is termed as
Hacking.
•It’s an anti-society activity.
•It says, there always exists more than one way to solve the
problem.
•The terms Hacker and Hacking are being misinterpreted
and misunderstood with negative sidelines.
6. HACKER WHO ARE THEY ?
Hackers are Intelligent Computer Professionals.
Motive/Intent
To gain in-depth knowledge of a system, what’s happening
at the backend, behind the screen
To find possible security vulnerabilities in a system.
They create security awareness by sharing knowledge. It’s a
team work.
7. CRACKERS/ATTACKERS
An Individuals who break into computers with malicious intent.
Motive/Intent –
•To seek unauthorized access into a system and cause damage or
destroy or reveal confidential information.
•To compromise the system to deny services to legitimate users for
troubling, harassing them or for taking revenge.
Effects- Can cause financial losses & image/reputation damages,
•Defamation in the society for individuals or organizations
8. PHREAKS
•Phreaks – These are persons who use computer devices and
software to break into phone networks.
•Motive/Intention- To find loopholes in security in phone
network and to makes phone calls at free of cost!!!
•Effects- You may have to big amount of phone bills, for doing
nothing!!!
9. SCRIPT KIDDIES
•Script Kiddies – These are persons not having technical skills to hack
computers.
•Motive/Intention- They use the available information about known
vulnerabilities to break into remote system.
•it’s an act performed for a fun or out of curiosity.
10. HATS OFF
•White Hat Hackers – They use their knowledge and skill set for good, constructive
intents. They find out new
Security loopholes and their solution.
E.g.- LIKE ME.. As I’m Doing It Right Now ( I Hope So!!!)
• Black Hat Hacker- They use their knowledge and skill set for illegal activities
destructive intents.
E.g.- to gain money (online robbery), to take revenge. Disgruntled
Employees is the best example of Black Hats. Attackers (Black Hat HACKERS) are not at
all concerned with security
professionals (White hat hackers). Actually these hackers are Bad Guys!!!`
12. ETHICAL HACKER STRATEGIES
“The one who can hack it, can only secure it”
“If you want to catch criminal then you’ll have to think like
criminal”
• What to protect?
• How to protect?
• Against whom?
• How much resources needed?
13. •Understand Client Requirements for Security / Vulnerability Testing.
• In Preparation Phase, EH will sign an NDA with the client.
• Internal / External Testing.
• Conduct Network Security Audits/ VAPT.
• Risk Assessment & Mitigation
•Documenting Auditing Reports as per Standards.
•Submitting Developer as well as remediation reports.
• Implement remediation for found vulnerabilities.
ETHICAL HACKER STRATEGIES
18. A consultant was hired by a business executive to test the security of
the executive's enterprise. The consultant was not hired to try to hack
through the firewall or bypass the intrusion detection system. He was
hired to see how easy it would be for a motivated intruder to gain
physical access to the company's mission-critical systems.
So the consultant created a fake company ID badge for himself. He
even simulated a magnetic swiping strip on the back of the ID by using
a piece of electrical tape. He used this fake ID to get into the company's
main building, then made his way up to the data centre where he
began swiping his fake ID badge through the scanner. After several
failed attempts, a friendly employee walked up and said, "Sometimes,
that thing doesn't work." The friendly fellow proceeded to swipe his
own badge, letting the consultant into the data centre.
19. At that point, the consultant walked to the centre of the room, raised his
arms, and said, "Okay everyone, I'm conducting a surprise security
audit. I need everyone to leave the room immediately." Although there
were a few surprised faces, all the employees in the data centre filed
out.
The consultant pulled out his cell phone, called the executive who hired
him, and said, "Guess where I am?"
24. VULNERABILITY RESEARCH
Vulnerability research is process of finding vulnerabilities,
threats & loopholes in server/ system.
Includes Vulnerability Assessment & Penetration Testing.
Vulnerability notes can be search on internet via Number,
CVE.
25. VULNERABILITY RESEARCH REFERENCES

http://web.nvd.nist.gov/
• US – CERT also publishes CVD on http://www.us-cert.gov
1. Contains Alerts which can be helpful to administrator.
2. It doesn’t contain solutions.
29. CONCLUSION
Security is important because prevention is better than cure.
Community of Hackers.
Security Involves five phases.
Ethical Hacking involves Conducting Security Audits,
Vulnerability, Assessment & Penetration testing.
Vulnerability Research is process of discovering different
vulnerabilities in technology & applications.
