FAQs for Cyber Security

Cybersecurity is the practice of protecting systems, networks, and programs from digital attacks. These cyberattacks are usually aimed at accessing, changing, or destroying sensitive information; extorting money from users via ransomware; or interrupting normal business processes.

Comprehensive overview of several key concepts in cybersecurity and information security. Here's a summary of each:

Information Security vs. Cybersecurity:

Information security (InfoSec) involves securing all forms of data, digital or analog, wherever they are stored, while cybersecurity specifically focuses on protecting digital data from being compromised or attacked. Cybersecurity is often considered a subset of information security due to its narrower focus.

Botnet:

A botnet is a network of computers infected with malicious software that allows a hacker to control them remotely. Botnets are commonly used to carry out various cybercrimes, including DDoS attacks, data theft, and malware distribution.

Attack Surface:

An attack surface refers to all the potential points of vulnerability in a system that an attacker can exploit to gain unauthorized access. This includes software, hardware, networks, and even human factors.

Phishing Attack:

Phishing is a type of cyberattack where attackers send fraudulent emails to trick recipients into revealing sensitive information or downloading malware. It's typically carried out on a large scale.

Spear Phishing:

Spear phishing is a targeted form of phishing where attackers tailor their fraudulent emails to specific individuals or organizations, making them appear more legitimate and increasing the likelihood of success.

Ransomware Attack:

Ransomware is a type of malware that encrypts files, databases, or applications, denying access to the victim unless a ransom is paid. It's a significant threat to organizations of all sizes.

Denial-of-Service (DDoS) Attack:

In a DDoS attack, hackers flood a system, network, or website with a massive amount of traffic, overwhelming its capacity and making it unavailable to legitimate users.

Hackers:

Hackers who threaten software security can range from individuals to well-funded criminal organizations or nation-states. They may engage in various types of cyberattacks, including hacking, phishing, or insider threats, with the goal of financial gain, political influence, or disruption.
