Study Notes

Cybersecurity Threats

Cyberthreats are potential malicious activities aiming to damage, steal data, or disrupt digital operations.

Types of Cyber Threats

Data Breach: Unauthorized leak or transfer of sensitive data from a secure to an insecure environment. This might involve copying, transmitting, viewing, or stealing data.
- Example: Students' confidential record information mistakenly viewed or misused.
Removable Media: Physical storage devices like thumb drives, CDs, DVDs, and external hard drives can carry malware if infected or inappropriately used.
- Devices can be intentionally or unintentionally connected to a computer and infect it with malware.
Unpatched Software Vulnerabilities: Software lacking updates creates gaps that malicious actors can exploit to access systems.
- Outdated software without the newest security patches makes systems vulnerable to attacks.

Types of Cyber Threats - Continued

Malware and Viruses: Malicious software meant to disrupt or steal data from computer systems.
- Examples include viruses, worms, trojans, spyware, and adware.
Phishing and Ransomware: Phishing involves tricking users into giving up login credentials, while ransomware encrypts data to extort money for its recovery.
Social Engineering Attacks: Exploiting human psychology to gain access to systems or data.
- Tactics include pretexting (creating believable scenarios) and baiting (offering tempting incentives to entice victims).
- Phishing uses deceptive communications to trick victims into revealing sensitive information.
Distributed Denial of Service (DDoS) Attacks: Overwhelm systems with traffic, preventing legitimate users from accessing them.
- Attackers use a network of compromised computers to flood the target system.

Insider Threats and Data Breaches

Negligence: Employees accidentally exposing sensitive data or failing to follow security protocols.
Malicious Intent: Employees intentionally stealing or leaking data for personal gain or sabotage.
Compromised Accounts: Unauthorized access to accounts by attackers compromising employee credentials.

Protecting Against Cybersecurity Threats

Strong Passwords: Use complex, unique passwords for different accounts to hinder unauthorized access.
Security Software: Install and regularly update antivirus and anti-malware software to defend against threats.
Regular Updates: Keep operating systems and applications updated with the latest security patches to close vulnerabilities.
Employee Training: Educate employees about cybersecurity threats, best practices, and how to protect sensitive information.
