Information security is a state of well-being of information and infrastructure in which the possibility of theft, tampering, and disruption of information and services is low or tolerable

A vulnerability refers to a weakness in the design or implementation of a system that can be exploited to compromise the security of the system. It is frequently a security loophole that enables an attacker to enter the system by bypassing user authentication. There are generally two main causes for vulnerable systems in a network, software or hardware misconfiguration and poor programming practices. Attackers exploit these vulnerabilities to perform various types of attacks on organizational resources.

▪ Common Reasons for the Existence of Vulnerabilities ▪ Hardware or software misconfiguration

What is Hacking?

Hacking in the field of computer security refers to exploiting system vulnerabilities and compromising security controls to gain unauthorized or inappropriate access to system resources. It involves a modifying system or application features to achieve a goal outside its creator’s original purpose. Hacking can be done to steal, pilfer, or redistribute intellectual property, thus leading to business loss. Hacking on computer networks is generally done using scripts or other network programming. Network hacking techniques include creating viruses and worms, performing denial-of-service (DoS) attacks, establishing unauthorized remote access connections to a device using trojans or backdoors, creating botnets, packet sniffing, phishing, and password cracking. The motive behind hacking could be to steal critical information or services, for thrill, intellectual challenge, curiosity, experiment, knowledge, financial gain, prestige, power, peer recognition, vengeance and vindictiveness, among other reasons.

Who is a Hacker?

A hacker is a person who breaks into a system or network without authorization to destroy, steal sensitive data, or perform malicious attacks. A hacker is an intelligent individual with excellent computer skills, along with the ability to create and explore the computer’s software and hardware. Usually, a hacker is a skilled engineer or programmer with enough knowledge to discover vulnerabilities in a target system. They generally have subject expertise and enjoy learning the details of various programming languages and computer systems.

3. Explain Ethical Hacking Concepts and Scope

Ethical Hacking Concepts

An ethical hacker follows processes similar to those of a malicious hacker. The steps to gain and maintain access to a computer system are similar irrespective of the hacker’s intentions.

What is Ethical Hacking?

Ethical hacking is the practice of employing computer and network skills in order to assist organizations in testing their network security for possible loopholes and vulnerabilities. White Hats (also known as security analysts or ethical hackers) are the individuals or experts who perform ethical hacking. Nowadays, most organizations (such as private companies, universities, and government organizations) are hiring White Hats to assist them in enhancing their cybersecurity. They perform hacking in ethical ways, with the permission of the network or system owner and without the intention to cause harm. Ethical hackers report all vulnerabilities to the system and network owner for remediation, thereby increasing the security of an organization’s information system. Ethical hacking involves the use of hacking tools, tricks, and techniques typically used by an attacker to verify the existence of exploitable vulnerabilities in system security.

Reasons why organizations recruit ethical hackers

▪ To prevent hackers from gaining access to the organization’s information systems

▪ To uncover vulnerabilities in systems and explore their potential as a risk

▪ To analyze and strengthen an organization’s security posture, including policies, network protection infrastructure, and end-user practices

▪ To provide adequate preventive measures in order to avoid security breaches

▪ To help safeguard the customer data

▪ To enhance security awareness at all levels in a business

Scope and Limitations of Ethical Hacking

Security experts broadly categorize computer crimes into two categories: crimes facilitated by a computer and those in which the computer is the target. Ethical hacking is a structured and organized security assessment, usually as part of a penetration test or security audit, and is a crucial component of risk assessment, auditing, counter fraud, and information systems security best practices. It is used to identify risks and highlight remedial actions. It is also used to reduce Information and Communications Technology (ICT) costs by resolving vulnerabilities. Ethical hackers determine the scope of the security assessment according to the client’s security concerns. Many ethical hackers are members of a “Tiger Team.” A tiger team works together to perform a full-scale test covering all aspects of the network, as well as physical and system intrusion. An ethical hacker should know the penalties of unauthorized hacking into a system. No ethical hacking activities associated with a network-penetration test or security audit should begin before receiving a signed legal document giving the ethical hacker express permission to perform the hacking activities from the target organization. Ethical hackers must be judicious with their hacking skills and recognize the consequences of misusing those skills.

Myth: AI will Replace Ethical Hackers ?

AI-driven ethical hacking is undoubtedly a powerful tool within the arsenal of ethical hackers, but it is crucial to recognize that it does not operate in isolation; rather, it complements, rather than replaces, human expertise.

▪ While AI technologies can automate certain aspects of ethical hacking tasks and significantly enhance efficiency, they cannot replace the creativity, critical thinking, and complex knowledge that human ethical hackers bring to tables.

▪ Ethical hacking involves determining how digital objects work and making them safer. It is like solving a puzzle in which you explore the computer staff and networks. You need to know about different software and hardware, and be ready for new challenges. The following rules and laws are as important as identifying problems:

▪ Although artificial intelligence (AI) tools can make the hacking process faster and easier, they are imperfect. Humans need to oversee them, ensure they are working correctly, and interpret the results. Sometimes, ethical hacking involves making difficult decisions where strict rules may not apply; that is, where human judgment becomes crucial. Humans can think of attackers, identify potential points of entry, and exploit vulnerabilities in ways that AI systems may struggle to comprehend. Moreover, ethical human hackers can leverage their knowledge and contextual understanding to craft tailored mitigation strategies to address the specific needs and challenges of a given system or network.

▪ AI-driven ethical hacking is beneficial for cybersecurity; however, it should not replace human hackers. When AI and humans work together, organizations can improve their cybersecurity and protect themselves against different threats. This combination of human creativity and technology can improve ethical hacking and cybersecurity better in the future.
