Study Notes
Information Assurance Basics
- Information assurance focuses on protecting information from damage, alteration, and leakage throughout its lifecycle: collection, processing, storage, and transmission.
- Importance of information assurance includes preventing privacy breaches and cybercrimes in an increasingly connected world.
Key Statistics
- As of July 2024, 5.45 billion people use the internet globally, accounting for 67.1% of the world’s population, with 86.98 million users in the Philippines.
- Major data breaches in 2024 included:
- AT&T: 7.6 million current and 65.4 million former customers
- MOVEit: 77 million
- Ticketmaster: 560 million records
- Tile: 450 million
- Dell: 49 million
- Bank of America: 57,000
- Jollibee Foods Corporation: 11 million
Principles of Information Security
- The three main goals are confidentiality, integrity, and availability, which must be supported through administrative, physical, and technical measures.
- The necessity for information security is driven by increasing privacy guarantees and the need to protect sensitive technologies from global threats.
Key Terms in Information Security
- Authentication: A process that ensures information exchanged between parties is not altered or deleted, and verifies the legitimacy of the sender and receiver.
-
Non-repudiation: Security measures that prevent claims from senders or receivers that messages were not sent, received, or delivered. Categories include:
- Non-repudiation of origin: Prevents the sender from claiming they did not send a message.
- Non-repudiation of delivery: Prevents the receiver from disputing the delivery of a message.
- Non-repudiation of receipt: Prevents the receiver from claiming they did not receive a message.
Cryptography
- Cryptographic techniques are divided into symmetric key systems (same key for encryption and decryption) and public key systems (different keys).
- Cryptography protocols utilize these techniques to ensure secure communication and message integrity, including methods for authentication, confidentiality, and non-repudiation.
Digital Signatures and Hash Functions
- Digital Signature: Provides data integrity and authentication by hashing a document with the signature's private key.
- Hash Function: Transforms input data of arbitrary length into a fixed-length hash value, efficiently summarizing the data.
Malware Overview
- Malware: Malicious software designed to harm computers, file systems, or networks.
- Types of malware include:
- Worms: Self-replicating malware that spreads independently.
- Viruses: Malicious code embedded within another program, requiring that program to run for the virus to activate.
