Study Notes
Intrusion
Network Intrusion
- Unauthorized access to a computer network, often to steal sensitive data or disrupt operations
- Types of network intrusions:
- Insider threats: Authorized personnel with access to the network
- Outsider threats: Unauthorized individuals gaining access
- Methods of network intrusion:
- Hacking: Unauthorized access using technical skills
- Phishing: Tricking users into revealing sensitive information
- Backdoors: Secretly installed malware allowing unauthorized access
- Detection and prevention methods:
- Firewalls and intrusion detection systems
- Encryption and secure protocols
- Regular software updates and patches
Social Engineering
- Psychological manipulation to trick individuals into divulging sensitive information or gaining unauthorized access
- Types of social engineering attacks:
- Phishing: Fraudulent emails, texts, or messages
- Pretexting: Creating a fake scenario to gain trust
- Baiting: Leaving malware-infected devices or storage devices in public areas
- Quid pro quo: Offering services or benefits in exchange for sensitive information
- Prevention methods:
- Employee education and awareness
- Verification of identities and requests
- Implementing strict security policies
SQL Injection
- Type of web application security vulnerability
- Occurs when an attacker injects malicious SQL code to access or modify sensitive data
- Methods of SQL injection:
- Classic SQL injection: Inserting malicious code as user input
- Blind SQL injection: Inferring database structure and data without direct output
- Time-based SQL injection: Inferring data by measuring response times
- Prevention methods:
- Input validation and sanitization
- Prepared statements and parameterized queries
- Regular security audits and penetration testing
Network Security Threats
- Network intrusion: unauthorized access to a computer network to steal sensitive data or disrupt operations
- Insider threats: authorized personnel with access to the network can intentionally or unintentionally cause harm
- Outsider threats: unauthorized individuals gaining access to the network using hacking, phishing, or backdoors

- Classic SQL injection: inserting malicious code as user input to access or modify sensitive data
- Blind SQL injection: inferring database structure and data without direct output
- Time-based SQL injection: inferring data by measuring response times
Prevention Methods
- Implementing firewalls and intrusion detection systems to detect and prevent network intrusions
- Encrypting data and using secure protocols to protect against hacking and phishing
- Conducting regular software updates and patches to prevent exploitation of vulnerabilities
- Educating employees about social engineering attacks and implementing strict security policies
- Validating user input and sanitizing data to prevent SQL injection attacks
- Using prepared statements and parameterized queries to prevent SQL injection attacks
