Study Notes
Cryptographic Algorithms
- Triple DES (3DES) is a symmetric-key block cipher that enhances security by applying the DES algorithm three times to each data block.
- RSA, PGP, and ECC are classified as asymmetric cryptographic algorithms, which use a pair of keys for encryption and decryption.
Reverse Proxy
- A reverse proxy is located at the edge of a cloud network to manage and direct traffic based on content compliance with security policies.
- Functions of a reverse proxy include directing traffic to internal services while ensuring that the traffic adheres to established security guidelines.
Evaluation Process Errors
- A false positive occurs when a test incorrectly identifies a condition as present, thus leading to erroneous conclusions in evaluations.
Email Attachment Issue
- An employee's inability to open an email attachment, such as Invoice1043.pdf, may indicate a double file extension is being used to disguise the true nature of the file.
- Forensics such as quick pop-ups during attempts to open the file can signal potential security threats, possibly hinting at malicious intent behind the attachment.
