Study Notes
Security Risks
- Phishing: Attackers trick individuals into providing sensitive information by impersonating a trustworthy entity. Typically happens through email but can also occur on social media, phone calls, or text messages
- Pharming: Redirects users from legitimate to fraudulent websites without their knowledge. Can result in the theft of sensitive information like login credentials or personal data
- Spoofing: Falsifying the origin of communication or data to deceive or impersonate another entity. Impacts network security, email, and other forms of digital communication.
Types of Malware
- Virus: A type of malicious software that attaches itself to legitimate files or programs and spreads to other files or systems when the infected file is executed.
- Trojan Horse (Trojan): Disguises itself as a legitimate program to trick users into installing it. Unlike viruses or worms, it doesn’t self-replicate and relies on user interaction to spread.
- Worm: A type of malicious software that replicates itself to spread to other computers and networks. It doesn't require a host file or user intervention to propagate.
Other Security Risks
- DoS (Denial of Service): An attack that attempts to make a computer or network unavailable to legitimate users.
- Botnet: A network of compromised computers controlled by an attacker that can be used to launch attacks or distribute malware.
- Spam: Unwanted junk email.
-
Cyber Vandalism: Deliberate and malicious alteration, destruction, or defacement of digital information or resources. Includes:
- Website Defacement: Changing the appearance of a website to display unauthorized content.
- Data Tampering: Modifying or corrupting data to make it unusable.
- Destruction: Deleting or rendering digital resources inaccessible.
Data Loss Consequences
- Financial Loss: Can result in significant financial repercussions, including loss of revenue, legal costs, and expenses related to data recovery.
- Operational Disruption: Can disrupt normal business operations, leading to decreased productivity, delays in delivering services or products.
- Reputation Damage: Can damage a company’s reputation, leading to loss of customer trust and confidence.
- Legal and Regulatory Consequences: Depending on the nature of the data, there could be legal and regulatory repercussions, including fines and penalties for non-compliance with data protection laws.
- Loss of Competitive Advantage: Data can be a critical asset for businesses. Losing proprietary or strategic data can lead to a loss of competitive advantage and hinder business growth.
- Intellectual Property Loss: Can result in the loss of valuable intellectual property, such as research and development data, designs, or proprietary algorithms.
- Data Recovery Costs: The process of recovering lost data can be expensive, especially if it involves specialized recovery services or technology.
- Decreased Productivity: Individuals and organizations may experience decreased productivity while trying to recover lost data or recreate it from scratch.
Bots (Robots)
- Bots: A software application that performs automated tasks over the internet. Bots can be used for a wide range of purposes, both legitimate and malicious
-
