Two types of computer software are system software and application software.
Three main objectives of information security are:
1. Confidentiality: Ensuring that only authorized individuals or systems have access to sensitive information. This objective aims to prevent unauthorized disclosure or access to data.
2. Integrity: Ensuring that data remains accurate, complete, and unaltered during storage, processing, and transmission. This objective aims to prevent unauthorized modification or tampering of data.
3. Availability: Ensuring that information and systems are accessible and usable by authorized individuals whenever needed. This objective aims to prevent disruptions or denial of service attacks that may hinder access to information or systems.

Four security attacks are:
1. Malware: Malicious software designed to harm or exploit computer systems or networks. Examples include viruses, worms, Trojans, and ransomware.
2. Phishing: A type of attack where attackers impersonate legitimate entities to trick individuals into revealing sensitive information such as passwords or credit card details.
3. Denial of Service (DoS): An attack that aims to disrupt the availability of a system or network by overwhelming it with excessive traffic or resource consumption.
4. Man-in-the-Middle (MitM): An attack where an attacker intercepts and alters communication between two parties without their knowledge. This allows the attacker to eavesdrop, modify, or inject malicious content into the communication.
Five types of malware are:
1. Virus: A self-replicating program that attaches itself to other programs or files and spreads by infecting them. Viruses can cause damage to files, software, and systems.
2. Worm: A standalone program that replicates itself and spreads across networks without requiring a host file. Worms can consume network bandwidth and cause system slowdowns.
3. Trojan: A program that disguises itself as legitimate software but performs malicious actions in the background. Trojans can steal sensitive information, create backdoors, or provide remote access to attackers.
4. Ransomware: A type of malware that encrypts files on a victim's system and demands a ransom in exchange for the decryption key. Ransomware can cause significant data loss and financial harm.
5. Spyware: Software that secretly gathers information about a user's activities without their consent. Spyware can track keystrokes, capture screenshots, and collect personal or sensitive information.
