Study Notes
Cyber Security
- Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks.
- Cyber threats are attacks mounted against digital devices by means of cyberspace, and a probability that a specific type of attack may occur.
Cyber Attacks
- A cyber attack is an attempt by hackers to damage or destroy a computer network or system, and an active offensive action where a bad actor is attempting to compromise a system.
Categories of Cybersecurity Threats
- Cybersecurity threats come in three broad categories of intent: financial gain, disruption, and espionage.
Types of Cybersecurity Threats
- Phishing: an email-borne attack that involves tricking the email recipient into disclosing confidential information or downloading malware by clicking on a hyperlink in the message.
- Spear Phishing: a more sophisticated form of phishing where the attacker learns about the victim and impersonates someone they know and trust.
- Ransomware: an attack that involves encrypting data on the target system and demanding a ransom in exchange for letting the user have access to the data again.
- Malware: a common cyberattack where malware executes unauthorized actions on the victim's system.
- Adware: a form of malware that hides on your device and serves you advertisements, and may also monitor your behavior online.
- Spyware: malicious software designed to enter your computer device, gather data about you, and forward it to a third-party without your consent.
- Trojans: a type of malware that enters a target system looking like a standard piece of software, but then lets out the malicious code once inside.
- Virus: a type of self-propagating malware that infects other programs/files of a target system.
- Worms: malware designed to propagate itself into other systems, often without any interaction on the user's behalf.
- Denial of Service attack: where an attacker takes over many devices and uses them to invoke the functions of a target system, causing it to crash from an overload of demand.
- Attacks on IoT Devices: IoT devices like industrial sensors are vulnerable to multiple types of cyber threats, including hackers taking over the device to make it part of a DDoS attack and unauthorized access to data being collected.
- Data Breaches: a theft of data by a malicious actor, with motives including crime, desire to embarrass an institution, and espionage.
Cyber Safety Tips
- Cyber safety tips: protect yourself against cyberattacks by using strong passwords, using anti-virus software, always updating your operating systems and software, and being cautious when opening email attachments from unknown senders.
Cyber Security
- Cyber security is the practice of defending computers, servers, mobile devices, electronic systems, networks, and data from malicious attacks.
- Cyber threats refer to attacks mounted against digital devices through cyberspace, which is a virtual space that doesn't exist but is a metaphor for understanding digital weaponry.
Cyber Threats
- Types of cyber threats:
- Cyber attacks: an attempt by hackers to damage or destroy a computer network or system.
- Cyber threats: a probability that a specific type of attack may occur.
- Categories of cyber threats based on intent:
- Financial gain
- Disruption
- Espionage
- Corporate espionage

- Adware: a form of malware that hides on a device and serves advertisements, monitoring online behavior to target specific ads.
- Spyware: malicious software designed to enter a computer device, gather data about the user, and forward it to a third-party without consent.
- Trojans: a type of malware that enters a target system looking like a standard piece of software, but then releases malicious code.
- Virus: a type of self-propagating malware that infects other programs or files of a target system.
- Worms: malware designed to propagate itself into other systems, often without user interaction.
- Denial of Service (DoS) attack: where an attacker takes over many devices and uses them to invoke the functions of a target system, causing it to crash from an overload of demand.
- Attacks on IoT Devices: IoT devices are vulnerable to multiple types of cyber threats, including hackers taking over the device to make it part of a DDoS attack and unauthorized access to data being collected.
- Data Breaches: a theft of data by a malicious actor, often motivated by crime, a desire to embarrass an institution, or espionage.
Safeguarding
- Cyber safety tips:
- Do not open email attachments from unknown senders.
- Use strong passwords that are not easily guessable.
- Use anti-virus software to detect and remove threats.
- Always update operating systems and software.
- Online safety is important regardless of age or life stage, especially with the increasing integration of the internet into daily life.
