Social engineering refers to the manipulation of individuals to gain unauthorized access to sensitive information or systems. Various types of social engineering include:
Phishing: Attackers impersonate legitimate entities via email, phone calls, or messages to deceive users into revealing personal information or clicking on malicious links.
Pretexting: Attackers fabricate a scenario or pretext to gain the trust of individuals and extract sensitive information or access to systems.
Baiting: Attackers offer enticing incentives or rewards, such as free software downloads or USB drives, containing malware to lure users into compromising their security.
Tailgating: Attackers physically follow authorized personnel into restricted areas or buildings, exploiting trust and social norms to gain unauthorized access.
Quid Pro Quo: Attackers offer a service or benefit in exchange for sensitive information or access to systems, exploiting reciprocity.
These tactics exploit human psychology and trust to bypass technical security measures, highlighting the importance of employee awareness and education in mitigating social engineering attacks.

Encryption is the process of converting plaintext or readable data into ciphertext or scrambled data using cryptographic algorithms and keys. It ensures data confidentiality by making it unreadable to unauthorized users, thus protecting sensitive information from interception or unauthorized access.Read more
Encryption is the process of converting plaintext or readable data into ciphertext or scrambled data using cryptographic algorithms and keys. It ensures data confidentiality by making it unreadable to unauthorized users, thus protecting sensitive information from interception or unauthorized access.
Symmetric encryption uses a single shared key for both encryption and decryption. It is fast and efficient for encrypting large amounts of data but requires securely sharing the key between communicating parties.
Public-key encryption, also known as asymmetric encryption, uses a pair of keys: a public key for encryption and a private key for decryption. The public key can be freely distributed, while the private key is kept secret. Public-key encryption provides secure communication without the need to share keys in advance, enabling secure data exchange over insecure channels.
In summary, symmetric encryption uses a single shared key, while public-key encryption uses a pair of keys for encryption and decryption.
