    Study Notes

    Encryption and Digital Signatures

    • The sender uses a private key to encrypt messages for achieving confidentiality.
    • A digital signature is used to ensure authenticity, integrity, and non-repudiation of a message.

    Hash Function and Digital Signature

    • A hash function is used to create a digital signature by creating a fixed-length string (digest) from a variable-length message.
    • The sender's private key is used to decode a digital signature.

    Public Key Infrastructure (PKI)

    • A Public Key Infrastructure (PKI) is used to manage public-private key pairs, certificates, and CAs.
    • The purpose of a PKI is to provide authentication, encryption, and digital signatures.

    Certification Authority (CA)

    • A Certification Authority (CA) is responsible for issuing, revoking, and managing digital certificates.

    Digital Certificate

    • A digital certificate binds together a public key with an entity's identity information.

    Network Security

    • A firewall is used to filter incoming and outgoing network traffic based on security rules.
    • AAA in network security mechanisms stands for Authentication, Authorization, and Accounting.

    Intrusion Detection System (IDS)

    • The purpose of an Intrusion Detection System (IDS) is to detect and alert on potential security threats.

    CIA Triad

    • The CIA Triad consists of Confidentiality, Integrity, and Availability.
    • Accountability is NOT one of the elements of the CIA Triad.

    Security Policies

    • An access control policy specifies the rules for accessing resources.
    • A privacy policy describes how personal data is handled and protected.
    • An acceptable use policy defines the rules for using company resources.
    • An auditing policy explains the procedures for tracking and monitoring user activities.

    Authentication and Authorization

    • The purpose of authentication is to verify the identity of a user or device.
    • The three types of authentication factors are Something You Know, Something You Have, and Something You Are.
    • The purpose of authorization is to determine what resources a user can access.
    • Access control refers to the process of granting or denying access to resources.

    Encryption and Network Security

    • The purpose of encryption is to protect data confidentiality and integrity.
    • Network security controls include firewalls, IDS/IPS, and VPNs.

    Purpose of Security Measures

    • The purpose of demonstrating information systems security is to ensure the confidentiality, integrity, and availability of data.
    • The purpose of AAA is to manage access, authentication, and auditing.
    • The purpose of a VPN is to provide secure communication over the internet.
    • The purpose of a firewall is to filter incoming and outgoing network traffic.
    • The purpose of an IDS/IPS is to detect and prevent security threats.
    • A network security policy describes the rules and procedures for securing a network.
