Study Notes

Information Security and Its Importance

Information security protects digital information, regardless of its format or location.
Confidentiality, integrity, and availability are key principles of information security (CIA Triad).
Increased security often leads to reduced user convenience.

Understanding Threat Actors

Script kiddies: Individuals with limited technical knowledge who download automated attack software.
Threat actors: Groups or individuals with malicious intent who target information systems.

Types of Security Vulnerabilities and Attacks

Platforms: Weaknesses in hardware or software platforms.
Configurations: Improperly configured systems or applications.
Third parties: Vulnerabilities introduced by external software providers.
Patches: Unsolved security flaws in software, often patched with updates.
Zero-day vulnerabilities: Newly discovered flaws that attackers exploit before anyone recognizes them.

Understanding Attack Vectors

An attack vector is the path an attacker uses to penetrate a system, like email, wireless networks, removable media, or social media.

Social engineering manipulates vulnerabilities by exploiting individuals' trust and psychological biases.
Hoaxes: Spreading false information, often through emails, to manipulate users.
Watering hole attacks: Targeting a specific group with malware-infected websites or resources.

Common Physical Security Procedures

Dumpster diving: Searching through trash for valuable data.
Tailgating: Following an authorized person through a security door.
Shoulder surfing: Observing individuals entering sensitive information, like key codes.

Impacts of Security Attacks

Successful attacks can result in data loss, data exfiltration, data breaches, and identity theft.

Summary of Key Points

Information security is critical for protecting digital data.
Threat actors exploit various vulnerabilities, including platform flaws and zero-day exploits.
Attack vectors like email, wireless networks, and social media provide avenues for attacks.
Social engineering attacks rely on manipulating individuals, often through psychological methods.
Attacks can have significant consequences ranging from data loss to identity theft.
