Cloud and Mobile Device Security

Introduction

Illustration of cyber security official securing a mobile device In today's digitally connected world, wireless networks play a vital role in our daily lives, enabling us to access information and communicate seamlessly. However, with this convenience comes the risk of security threats and unauthorized access to our networks and sensitive data. In this module, we'll explore wireless threats and the essential measures and techniques for securing wireless networks effectively. By understanding the importance of encryption, authentication, and other security protocols, we can safeguard our networks against potential threats and ensure the confidentiality, integrity, and availability of our data.

Key Terms

Virus: A malicious program that self-replicates and spreads from one device to another, usually by attaching itself to legitimate files.
Worm: A type of virus that can exploit network vulnerabilities to spread automatically without human interaction.
Trojan: A malicious program disguised as legitimate software, tricking users into installing it, allowing attackers access to their systems.
Unpatched software: Software with known vulnerabilities that haven't been fixed with updates, leaving them susceptible to attack.
Password cracking: The process of guessing or using computational methods to gain unauthorized access to a user's password.
Advanced persistent threats (APTs): Highly sophisticated, targeted attacks by skilled adversaries aiming to gain long-term access to a system.
Baiting: Luring victims with attractive offers or threats to click on malicious links or open infected attachments.
Phishing/spear phishing: Sending emails or messages disguised as legitimate sources to trick users into revealing personal information. Spear phishing targets specific individuals or organizations.
Pretexting/blagging: Impersonating a trusted person or organization to gain access to information or systems.
Tailgating: Following closely behind authorized personnel to gain physical access to restricted areas.
Quid pro quo: Offering something in exchange for unauthorized access or information, exploiting a sense of obligation or reciprocity.
Wireless security: The measures and techniques employed to protect wireless networks from unauthorized access and attacks.
Encryption: The process of encoding data to prevent unauthorized access or interception.
Authentication: The process of verifying the identity of users or devices attempting to access a network.
SSID hiding: The practice of hiding the Service Set Identifier (SSID) of a wireless network to prevent unauthorized users from discovering and connecting to the network.
Rogue access points: Unauthorized wireless access points set up by malicious individuals to intercept network traffic and gain unauthorized access to the network.
Man-in-the-middle attacks: Attacks where attackers intercept and manipulate communication between two parties, leading to data interception or manipulation.
Denial-of-service attacks: Attacks that target wireless networks by flooding them with excessive traffic, causing network congestion and rendering services unavailable to legitimate users.
