Study Notes
Overview of Computer Security
- Computer security encompasses information privacy, data integrity, and system availability.
- Protects valuable resources, ensuring data in databases and systems remain intact and accessible without unauthorized changes.
Purpose of Computer Security
- Safeguards business processes to ensure they function without disruption.
- Ensures that information resources are available to the right people at the right time.
Consequences of Poor Computer Security
- Hindered access to critical data affecting decision making.
- Typical outcome of breaches includes unauthorized non-availability of information.
- Challenges may arise due to human or mechanical barriers.
Maintaining Confidentiality
- Authenticity is crucial to verify the identity of individuals accessing information.
- Data integrity must be maintained as information transitions between locations, emphasizing non-repudiation.
Core Concepts of Computer Security (CIA)
- Confidentiality: Protecting data from unauthorized disclosure.
- Integrity: Ensuring data is accurate, consistent, and trustworthy.
- Availability: Guaranteeing that information is accessible when needed.
Trends in Cyber Threats
- Significant rise in cyber threats, with over 2,200 daily cyberattacks reported in 2024.
- Victim of a data breach occurs every 39 seconds.
Common Cyber Threats
- Identity Theft: Unauthorized access to personal information (e.g., Social Security Number).
- Hacking: Illicit access to computer systems for information theft or damage.
- Malware: Malicious software harming computer users, encompassing viruses, worms, and spyware.
- Phishing: Deceptive practices to obtain personal information via misleading communications.
Categories of Cyber Threats
- Automated attacks, malicious intent cyber attacks, internal employee attacks, social engineering tactics, privacy attacks, and cyber espionage.
Automated Attacks
- Often undetected, these attacks are rapidly executed using automated tools, originating from human actions but requiring limited technological skills.
- Tools like SQL injection and Remote File Inclusion exemplify common automated attack methods.
SQL Injection
- A method allowing the execution of SQL commands through user input fields, enabling direct database querying.
Remote File Inclusion (RFI)
- Attack technique enabling the upload of malicious files to servers through vulnerabilities in service scripts.
Malicious Intent Cyber Attacks
- Target essential infrastructures, with notable attacks reported in sectors such as energy, banking, and media.
- Motivated by political reasons or theft.
Internal Employee (Insider) Cyber Attacks
- Influenced by personal circumstances, work situations, financial hardships, and hostile relationships, leading to potential security breaches.
Social Engineering
- Involves tricking individuals to provide information via phishing attempts using emails, phone calls, or misleading websites, commonly posing as urgent notifications.
Privacy and Identity-Related Attacks
- Identity theft arises when personal credentials are stolen and misused for unauthorized activities like renting properties or applying for loans.
Cyber Espionage
- Considered illegal by the majority, cyber espionage often goes underreported, with notable cases involving government allegations against corporations.
Balancing Usability and Security
- Organizations struggle to maintain user-friendly systems while ensuring robust security protocols are in place.
