Study Notes
Network Security
Network security is vital for protecting the confidentiality, integrity, and availability of data transmitted over networks. It involves implementing policies, technologies, and procedures to prevent unauthorized access, deny unauthorized use, detect intrusions, and recover from incidents. Key elements of network security include firewalls, intrusion detection systems, virtual private networks, and secure authentication protocols.
Cyber Attacks
Cyber attacks are acts of breaching digital devices, networks, and systems for the purpose of stealing, altering, or destroying information or interrupting normal business functions. These attacks can range from simple malware injection to sophisticated social engineering campaigns. Common types of cyber attacks include phishing, denial-of-service (DoS) attacks, man-in-the-middle attacks, SQL injection, and buffer overflow attacks.
Data Encryption
Data encryption is the process of converting plaintext into ciphertext using an algorithm that requires a key for decryption. This technology protects data during transmission across networks and when stored on media. Two primary forms of encryption are symmetric and asymmetric encryption. Symmetric encryption uses the same key for encryption and decryption, whereas asymmetric encryption employs two keys: a public key for encryption and a private key for decryption.
