Study Notes
AP CSP Cybersecurity
- Cybersecurity encompasses protecting digital systems and data from unauthorized access, use, disclosure, disruption, modification, or destruction. It involves various strategies and technologies to mitigate risks.
Data Protection
- Data protection refers to the policies and practices that ensure confidentiality, integrity, and availability of data. This includes measures to prevent unauthorized access, use, and disclosure.
- Key aspects of data protection include: data classification (identifying sensitivity levels), access control (limiting who can see what), data encryption (converting data to an unreadable format), backups (protecting against data loss), and data disposal (destroying data securely).
- Data breaches are a major concern, highlighting the importance of robust protections. They can result in financial loss, reputational damage, and legal penalties.
Encryption Methods
- Encryption converts readable data (plaintext) into an unreadable format (ciphertext) to protect it from unauthorized access.
- Common encryption methods include: symmetric-key algorithms (using the same key for encryption and decryption, e.g., AES), asymmetric-key algorithms (using a public key for encryption and a private key for decryption, e.g., RSA), and hash functions (generating a unique fixed-size output for a given input, e.g., MD5). Each has strengths and weaknesses concerning speed, key management, and security strength.
- The choice of encryption method depends on the specific requirements, such as the sensitivity of the data, computational resources, and the need for key exchange security.
Network Security
- Network security involves protecting computer networks from unauthorized access, use, and disruption.
- It includes various measures like firewalls (blocking unauthorized network traffic), intrusion detection systems (identifying malicious activities), access control lists (restricting access to network resources), and virtual private networks (creating secure connections over public networks).
- Network security vulnerabilities can be exploited to gain unauthorized access to sensitive data or resources.
Security Protocols
- Security protocols are sets of rules and procedures that govern the security of communication and data exchange across networks.
- Common protocols include: HTTPS (secure communication protocol for web traffic), SSH (secure shell for remote login), TLS/SSL (transport layer security protocols to encrypt communication channels), and SFTP (secure file transfer protocol). These protocols use encryption and authentication mechanisms to protect communication from eavesdropping and tampering.
- Different protocols are suitable for various purposes, each with advantages and disadvantages in terms of performance, security, and complexity.
Cyber Threats
- Cyber threats include various malicious activities aimed at compromising computer systems or networks.
- Main categories of threats include malware (viruses, worms, Trojans), phishing (deceiving users into revealing sensitive information), denial-of-service attacks (overloading systems to prevent legitimate users from accessing them), social engineering (manipulating individuals to gain access to information), and SQL injection attacks to compromise databases.
- The sophistication and frequency of cyber threats are increasing, demanding constant vigilance and adaptable security measures.
- Cybersecurity awareness and training for personnel is critical. User education is crucial to prevent social engineering and phishing tactics.
