What is Cyber Security?

Cyber security is the body of technologies, processes, and practices designed to protect networks, computers, programs, and data from attack, damage, or unauthorized access or misuse of authorized assets. The goal of cyber security is to reduce the risk of cyber attacks and protect organizations and individuals from the exploitation of security weaknesses and systems.

Cyber security threats are becoming more complex as hackers learn to adapt to security strategies. Companies will need to pay more than ever to land highly skilled cyber security professionals in order to secure their vulnerable assets from cyber attacks.

Common Types of Cyber Attacks

Here are some of the most common types of cyber attacks:

• General Malware
• Phishing
• Password Attacks
• Distributed Denial of Service (DDoS)
• Man in the Middle Attacks
• Drive-by Downloads
• Malvertising
• Rogue Softwares

Cyber breaches have become a major threat to organizations, both big and small. Cybersecurity is a solution that provides protection against unauthorized access to data centers and other computerized systems. It also aids in risk management and helps prevent data breaches, cyber attacks, and identity theft. The three main activities that cybersecurity aims to protect against are unauthorized modification, unauthorized deletion, and unauthorized access. These activities are synonymous with the CIA triad, which stands for confidentiality, integrity, and availability. Confidentiality involves preventing sensitive information from reaching the wrong people, integrity involves maintaining the consistency and trustworthiness of data, and availability involves maintaining all hardware and preventing bottlenecks.To mitigate cyber attacks, organizations must identify the malware or cyber threat, analyze and evaluate all affected parties and file systems, and patch the whole treatment. Calculating vulnerability, threat, and risk is crucial in ensuring the continued security of systems. Vulnerability refers to a known weakness of an asset that can be exploited by one or more attackers, threat refers to a new or newly discovered incident with potential to do harm to a system or organization, and risk refers to the potential for loss or damage when a threat exploits a vulnerability.To determine vulnerability, organizations can ask questions such as whether data is backed up and stored in a secure offsite location, what kind of antivirus protection is in use, and whether there is a data recovery plan in the event of a vulnerability being exploited. To assess threats, organizations can stay informed of current trends in cybersecurity, perform regular threat assessments, and conduct penetration testing. Finally, to manage risk, organizations can prioritize risks based on the likelihood of occurrence and potential impact, and develop strategies to mitigate them.

Risk Management for Cybersecurity

Risk in cybersecurity can result in financial losses, loss of privacy, reputational damage, legal implications, and even loss of life. Risk can be reduced by creating and implementing a risk management plan. Key aspects to consider when developing a risk management strategy include assessing risk and determining needs, prioritizing important breaches, and including a total stakeholder perspective.

A Scenario for Cybersecurity Defense

Cybercrime is a global problem that poses a threat to individual security and large international companies, banks, and governments. An incident response platform can automate the entire cybersecurity process, connecting security and ID software needed to keep a large company secured into a single dashboard. In the case of a security breach, the platform can orchestrate a chain of events that ultimately prevents the company from encountering a serious security disaster. The platform identifies and patches all vulnerabilities and notifies affected parties and relevant compliances and liability procedures.

The Early Days of Hacking

The definition of hacking has changed over time, particularly in the 1980s as a result of people like Robert T Morris and Kevin Mitnick. Hacking is about exploring and learning new things, digging into problems to find solutions in creative ways, and sometimes finding problems where there weren't any previously.

Reasons for Hacking

People may hack for fun, financial gain, political reasons, activism, or to test system security.

Why Hack?

Hacking is a tradition at MIT that goes back several decades, even preceding the computer definition of hacking. Sometimes, hacking is done for fun, as in the case of the Disney-MIT prank in 1998, or to prove a point, like when students hacked the windows systems at the William H Gates building to run Linux instead. Other times, hacking is done for the challenge and bragging rights, like when students turned the facade of a building into a Tetris game board. In the realm of computer-related hacking, some people learn to hack to prevent theft and protect their company from reputational damage or bankruptcy. Another reason to hack is to find flaws in your own system and fix them before they can be exploited by bad actors. Finally, some companies are starting to retaliate against attackers, and in order to do so, they need to have the same skills and knowledge as the attackers.

Types of Hackers

There are several types of hackers, starting with ethical hackers, who are hired to find vulnerabilities in a system and fix them. Black hat hackers, on the other hand, are intent on breaking into systems for malicious purposes, such as stealing data. Gray hat hackers are somewhere in between ethical and black hat hackers. Kevin Mitnick is an example of a black hat hacker who engaged in computer crimes for over a decade before being caught and convicted by the FBI.

Types of Hackers

There are three types of hackers: white hat, black hat, and gray hat. White hat hackers act for good and aim to improve the security of organizations. Black hat hackers engage in criminal activity and are motivated by money and thrill-seeking. Gray hat hackers may use tactics of black hat hackers but with a white heart focus, aiming to improve the security posture of the organization they are working with. Another type of hacking is hacktivism, which involves various tactics and means to achieve a goal.

Skills Required

To become a hacker, one needs to have basic computing knowledge, an understanding of operating systems, and familiarity with command line utilities. Basic networking concepts such as cables, switches, and hubs are also necessary. Problem-solving skills and the ability to accept failure and persevere are crucial. In this video, you will learn how to use different tools, understand networking protocols, security postures, and risk and vulnerability recognition.

Skills Required for Ethical Hacking

As part of this video series, you will need to develop a basic understanding of operating systems. While it may seem like a lot to cover, we will provide a mix of in-depth and surface-level material to help you become an ethical hacker.

Types of Attacks

As an ethical hacker, you may encounter different types of attacks. One common attack is defacing, which involves altering a website's homepage as a form of digital graffiti. Another common attack is a buffer overflow, which exploits high-profile vulnerabilities to control the execution of a program. Format string attacks can also be a precursor to buffer overflow attacks.

Denial of service (DoS) attacks are also common, which prevent legitimate users from accessing a service. This can be caused by a ping flood, malformed data, or other means. It's important to note that a DoS attack is not the same as a distributed denial of service (DDoS) attack. A DDoS attack is a coordinated effort using several hosts in different locations to overwhelm a server's resources. The first known DDoS attack used a tool called Stacheldraht, which was created in 1999.

Introduction to Penetration Testing

In this lesson, we will discuss penetration testing, its goals, and scope. Penetration testing is a process of testing to determine if a system can be penetrated or broken into, such as servers or applications. The goals of penetration testing include assessing an organization's security posture, identifying vulnerabilities, and helping them mitigate risks. The scope of penetration testing is defined by the agreement between the ethical hacker and the authorized person to give permission for testing. It is crucial to get a sign-off from the target organization and make sure the scope is clear in writing.

Syn Flood and Old Rod Attack

Syn flood is an attack that floods a server with a series of connection requests, making it unable to handle legitimate requests. Old Rod was a program used to attack servers like eBay and Yahoo back in February 2000. It was the first known distributed denial of service attack, which means there were multiple systems coordinated to create a denial of service condition.

Types of Attacks

Common types of attacks that ethical hackers may encounter include social engineering attacks, technical approaches, and physical access. Social engineering attacks involve tricking someone into revealing their username and password or clicking on a crafted email URL. Technical approaches involve running scans and using tools like Metasploit to gain access. Physical access is necessary to gain access to a particular system.

Goals of Penetration Testing

The goals of penetration testing are to assess an organization's security posture, identify vulnerabilities, help them understand their risks better, and access systems to find weaknesses. The result of penetration testing is a report that details findings, remediation activities, and how to mitigate risks.

Security Assessment vs. Penetration Testing

A security assessment is a collaborative approach with clients to assess their security posture and policies and procedures. It is more comprehensive than a penetration test and tailors output based on the risk appetite of the organization. A security assessment provides more details about fixes than a penetration test and assesses more factors to determine the organization's overall risk.

Scope of Penetration Testing

The scope of penetration testing is defined by the agreement between the ethical hacker and the authorized person to give permission for testing. It is crucial to get a sign-off from the target organization and make sure the scope is clear in writing. The scope may exclude areas that the organization deems too sensitive to touch.

Conclusion

Penetration testing is a crucial aspect of ethical hacking, and its scope and goals must be defined clearly. The ethical hacker must work collaboratively with the target organization, and the output must be tailored based on the organization's risk appetite. The report should detail findings and remediation activities to mitigate risks.

Penetration Testing and Footprinting

Penetration testing is important in identifying vulnerabilities in an organization's security system. However, it is essential to note that even if no significant penetration is achieved during the testing period, it does not mean that the organization is entirely secure. A dedicated and skilled attacker can take longer than a week to breach a system. Footprinting, on the other hand, involves gathering information about the target's scope, including domain names, IP addresses, system architecture, access control lists, and other relevant data. It is crucial to be exhaustive in the process and keep track of all the information gathered in a database or spreadsheet. The Wayback Machine or Archive.org is a useful tool for historical information about a website's evolution.

• Footprinting involves gathering information about the target's scope, including domain names, IP addresses, system architecture, access control lists, and other relevant data.
• It is crucial to be exhaustive in the process and keep track of all the information gathered in a database or spreadsheet.

The Wayback Machine

The Wayback Machine or Archive.org is a useful tool for historical information about a website's evolution. It provides a starting point for the reconnaissance process by showing what a website looked like in the past. This information can be helpful in narrowing down the focus of an attack.

Historical Look at Edureka.com

At archive.org, we can take a historical look at Edureka.com's website. The snapshots go back to 2013. Let's take a look at what the website looked like in 2014. We can browse more advanced screenshots to see how the company has evolved with its infrastructure and how it lays out its content.

Netcraft: Internet Research and Web Servers

Netcraft does internet research, including types of web servers that companies run. It has a web server service that shows the market share of web servers. We can search for Edureka.com and get information about the site, such as the net block owner, name server, and IP address. We can also get hosting history and see that it's hosted on a Linux system with an Apache web server.

Using DNS to Get More Information

We can use the utility "whois" to query the various regional internet registries to store information about domain names and IP addresses. We can use it to find out who owns a particular IP address. Using the command "dig" followed by a domain name, we can get back multiple IP addresses associated with that domain. Then, we can use "whois" with the IP address to get more information about the owner of that IP address.
