Malware, short for malicious software, refers to any software designed to harm or exploit computer systems. This includes viruses, worms, Trojans, ransomware, and spyware. Malware can infect computers and networks, steal sensitive information, damage files, and disrupt system operations. It is typically spread through infected email attachments, malicious websites, or compromised software.
2. Phishing
Phishing is a social engineering technique used by cybercriminals to trick individuals into revealing sensitive information, such as passwords, credit card details, or personal identification. Phishing attacks often involve sending deceptive emails that appear to be from a trustworthy source, such as a bank or a popular online service. These emails usually contain links to fake websites that mimic legitimate ones, aiming to steal login credentials or financial information.
3. Denial of Service (DoS) Attacks
Denial of Service attacks aim to disrupt the availability of a computer system or network by overwhelming it with a flood of illegitimate requests or traffic. This can result in the system becoming slow or completely unresponsive, preventing legitimate users from accessing the services. DoS attacks can be carried out using botnets, which are networks of compromised computers controlled by the attacker.
4. Insider Threats
Insider threats refer to malicious activities carried out by individuals within an organization who have authorized access to sensitive information or systems. These individuals may intentionally or unintentionally misuse their privileges to steal confidential data, sabotage systems, or compromise security. Insider threats can be challenging to detect and prevent, as the individuals responsible already have legitimate access to the targeted resources.
5. Social Engineering
