Symmetric encryption uses the same key for encryption and decryption, making it faster but less secure for key exchange. Asymmetric encryption uses separate keys, enhancing security but reducing speed.
Protects data in transit
Offers real-world use cases
Key Strengths
Strong encryption algorithms like AES and RSA are helpful for securing secure information. AES is favored for its efficiency, while RSA excels in key management.
Boosts personal security
Enhances business security
Social Engineering: The Human Firewall
Definition
Social engineering is a psychological manipulation technique used to trick individuals into divulging sensitive information or performing actions that compromise security.
Red Flags
Be alert for suspicious requests, urgent demands, or offers that seem too good to be true. Always verify the identity of the requestor through trusted channels.
Psychology
Attackers exploit human emotions such as fear, greed, and trust to bypass security measures and gain unauthorized access.
Malware Landscape
Viruses replicate and spread by attaching themselves to executable files or documents, causing data corruption and system instability.
Trojans disguise themselves as legitimate software to gain access to systems, often used to steal data or create backdoors for future attacks.
Ransomware encrypts files and demands payment for their decryption, causing significant financial and operational disruption.
