Explanation: The advantages are minimization of computer freezing and crashes, user privacy, and protection against viruses, worms, etc. Disadvantages include the system becoming slow, configuring firewalls correctly can be difficult, need to update the new software in order to keep security up to date.

Explanation: Attacks are Phishing, SQL Injections, and Password Attack.
Phishing: The attacker sends a large number of fraudulent emails and gains access to the system.
SQL Injections: The attacker gains access to the protected information by adding malicious code to the SQL server.
Password Attack: Attackers gain access to the passwords unethically and gain access to the confidential data.

Explanation: Black Hat hackers, often known as “crackers,” are a sort of cyber crime that gain illegal access to a user’s account or system in order to steal confidential data or introduce malware into the system for personal gain or to harm the company.

Explanation: Sendinc is not a tool that compromises email data. It is used to protect business email accounts and provides a fast web-based solution for businesses to start delivering secure emails. The other three are email hacking tools.

Explanation: During a hack, cyber-criminals first do research on the target, gathering data about the victim’s system and network. Then go ahead and attack. Once the attacker has gained access, he or she takes sensitive information.

Explanation: The Internet of Things (IoT) is a network of physical objects embedded with sensors, software, and other technologies to connect and exchange data with other devices and systems through the internet.

Explanation: Stuxnet is a popular and powerful worm that came into existence in mid 2010, which was very powerful as it was accountable for the cause of huge damage to Iran’s Nuclear program. It mainly targets the PLCs (Programmable Logic Controllers) in a system.

Explanation: Enumeration by cyber-attackers is also feasible via websites since attackers target websites in order to obtain the victim’s or target user’s IP address.

Explanation: Phishing is a type of cybercrime in which a person is digitally persuaded to disclose private information. Phishing comes in a variety of forms. Some of them employ malware and emails to divert users to various websites.

Explanation: Vulnerability is a term that refers to a weakness in a network or system that an attacker may exploit. Exploiting a weakness in security might have unintended and undesirable consequences.

Explanation: OS fingerprinting is an ethical hacking technique used for determining what operating system (OS) is running on a remote computer. OS Fingerprinting is the practice of examining data packets that come from a network in order to extract intelligence that may be utilized in future assaults.

Explanation: Extortion, identity theft, email hacking, digital surveillance, stealing hardware, mobile hacking, and physical security breaches are all examples of cyber assaults or activities.

Explanation: A threat is a possible danger that might lead to a security breach and cause harm to the system or network. Vulnerability is a word that refers to a flaw in a network or system that might be exploited by an attacker. Exploiting a security flaw might result in unexpected and unwanted effects. A cyber-attack is an attempt by attackers to alter, delete, steal or expose any specific data by gaining unauthorized access.

Explanation: The excess data that contains certain specific instructions in the memory for actions are projected by a cyber-criminal or penetration tester to break the system in a buffer-overflow attack.

Explanation: Botnets on infected mobile devices are waiting for orders from their owners. It starts a DDoS flood attack after receiving the owner’s instructions. As a result, calls are not connected or data is not sent.

Explanation: Pharming is a strategy and approach used by cybercriminals to create phony web pages and sites in order to mislead users into giving over personal information such as login IDs and passwords.

Explanation: In the case of hackers in the 1970s, hackers and cyber thieves found out how wired technologies operate and how they might be abused to obtain a competitive edge or misuse the technology.

Explanation: Login using ID will obviously take your ID in order to access your account and is not the headache of Tor. Privacy regarding instant messaging, browsing data, relay chats are some of the following online services protected by Tor.

Explanation: A threat is defined as a potential hazard that might result in a breach of security and cause harm to the system or network. Vulnerability is a term that refers to a weakness in a network or system that an attacker may exploit. Exploiting a weakness in security might have unintended and undesirable consequences.

Explanation: The objectives of network security are Confidentiality, Integrity, and Availability.
Confidentiality: The function of confidentiality is to keep sensitive company information safe from unwanted access. The confidentiality component of network security ensures that data is only accessible to those who are authorized to see it.
Integrity: This goal entails ensuring and preserving data accuracy and consistency. The purpose of integrity is to ensure that data is accurate and not tampered with by unauthorized individuals.
Availability: The purpose of availability in Network Security is to ensure that data, network resources, and services are always available to legitimate users, whenever they need them.

Explanation: Nation / State-sponsored hackers are those who are engaged or paid by a nation’s or state’s government to safeguard the country from cyber terrorists and other groups or individuals, as well as to expose their plans, communications, and activities.

Explanation: William Gibson, an American-Canadian fiction pioneer, and coiner, examined the many streams of technology and invented the word “cyberspace” in 1821. The phrase refers to linked technologies that aid in information exchange, interaction with digital devices, storage and digital entertainment, computer and network security, and other information technology-related matters.

Explanation: Grey Hat Hackers are a hybrid of ethical and unethical hacker personalities. They hack other people’s computers for fun, but they don’t hurt them, and they exploit network faults and vulnerabilities without the admin or owner’s awareness.

Explanation: Denial of Service, Man in the Middle, and Malware exploit the system causing a threat to security, hence they are considered as cybercrime. AES (Advanced Encryption Standard) provides security by encrypting the data.

Explanation: Ordinary files are targeted by hackers or other cyber criminals in order to disguise distinct data or information within another data file. You can reduce the risk of data leaking by employing steganography.

Explanation: The term “hacker” was coined at MIT (Massachusetts Institute of Technology) because individuals and highly competent professionals use computer languages to address various challenges. In this context, labels such as geeks and nerds have been coined.

Explanation: Wireless security is an important aspect of cyber-security. Wired Equivalent Privacy (WEP), Wi-Fi Protected Access (WPA), WPA2, and WPA3 are the most common kinds of wireless security. WEP is a famously insecure encryption protocol.

Explanation: This is a position in a company or organisation where an individual develops and maintains different systems and security tools for the company or organisation to which he or she belongs.

Explanation: Peer-to-peer includes phishing, as well as the distribution of Trojans and worms to individuals. The leakage of a huge number of people’s credit card data on the deep web, on the other hand, is classified as a computer-as-weapon cyber-crime.
