  • Cryptography: Cryptography is the practice of using mathematical algorithms to encrypt and decrypt data. Encryption is the process of converting plaintext into ciphertext, while decryption is the process of converting ciphertext back into plaintext. Cryptography can be used to protect data from unauthorized access, such as when data is transmitted over a network or stored on a computer.
  • PKI: PKI is a system that uses digital certificates to verify the identity of individuals and organizations. Digital certificates are issued by trusted certificate authorities (CAs). When a user wants to access a secure website, the website's server will request a digital certificate from the user's browser. The browser will then verify the digital certificate to ensure that it is valid. If the digital certificate is valid, the browser will allow the user to access the website.

  By understanding these cryptography and PKI concepts, you can lay the foundation for a strong cryptography and PKI program that will help to protect your organization's data from a wide range of threats.

  Encryption Basics: Symmetric vs. Asymmetric Encryption

  Encryption is the process of converting plaintext into ciphertext, while decryption is the process of converting ciphertext back into plaintext. Encryption is used to protect data from unauthorized access, such as when data is transmitted over a network or stored on a computer.

  There are two main types of encryption: symmetric encryption and asymmetric encryption.

  • Symmetric encryption uses the same key to encrypt and decrypt data. This makes symmetric encryption faster and more efficient than asymmetric encryption. However, it also means that if the encryption key is compromised, the attacker will be able to decrypt all of the data that was encrypted with that key.
  • Asymmetric encryption uses two different keys to encrypt and decrypt data. The public key is used to encrypt data, and the private key is used to decrypt data. This makes asymmetric encryption more secure than symmetric encryption because even if the public key is compromised, the attacker will not be able to decrypt the data without the private key.

  The CompTIA Security+ Cheat Sheet covers the basics of encryption, including the difference between symmetric and asymmetric encryption.

  Hashing Algorithms: SHA, MD5 (why it’s weak), HMAC

  Hashing algorithms are mathematical functions that convert data of any size into a fixed-size hash value. Hash values are used to verify the integrity of data, such as when data is transmitted over a network or stored on a computer.

  Some of the most common hashing algorithms include:

  • SHA: Secure Hash Algorithm (SHA) is a family of cryptographic hash functions that are used to create a condensed representation of data. SHA algorithms are used in a variety of applications, including digital signatures, message authentication codes, and password hashing.
  • MD5: Message Digest 5 (MD5) is a cryptographic hash function that is used to create a 128-bit hash value. MD5 is used in a variety of applications, including digital signatures, message authentication codes, and password hashing. However, MD5 is no longer considered secure and should not be used for new applications.
  • HMAC: HMAC (Hash-based Message Authentication Code) is a message authentication code that uses a cryptographic hash function to create a digital signature. HMAC is used to verify the integrity of data, such as when data is transmitted over a network or stored on a computer.

  The CompTIA Security+ Cheat Sheet covers the basics of hashing algorithms, including the SHA, MD5, and HMAC algorithms.

  PKI (Public Key Infrastructure): Certificates, CA, SSL/TLS

  Public key infrastructure (PKI) is a system that uses digital certificates to verify the identity of individuals and organizations. Digital certificates are issued by trusted certificate authorities (CAs). When a user wants to access a secure website, the website's server will request a digital certificate from the user's browser. The browser will then verify the digital certificate to ensure that it is valid. If the digital certificate is valid, the browser will allow the user to access the website.

  PKI is used in a variety of applications, including:

  • Secure websites: PKI is used to secure websites by encrypting the data that is transmitted between the website and the user's browser. This prevents attackers from eavesdropping on the data.
  • Email security: PKI is used to secure email by encrypting the email messages and attachments. This prevents attackers from reading the email messages and attachments.
  • Code signing: PKI is used to sign code to verify the integrity of the code. This prevents attackers from tampering with the code.

  The CompTIA Security+ Cheat Sheet covers the basics of PKI, including digital certificates, CAs, and SSL/TLS.

  Identity & Access Management (IAM)

  Identity and access management (IAM) is the process of managing the identities of users and their access to resources. IAM is essential for ensuring that only authorized users have access to the resources they need to do their jobs.

  IAM involves the following tasks:

  • User provisioning: Creating and managing user accounts.
  • Authentication: Verifying the identity of users.
  • Authorization: Granting users access to the resources they need.

  IAM is a critical part of any security program. By implementing strong IAM practices, you can reduce the risk of unauthorized access to your resources.

  The CompTIA Security+ Cheat Sheet covers the basics of IAM, including user provisioning, authentication, authorization, and access management.

  Authentication Methods: MFA, Biometric, Tokens

  Authentication is the process of verifying the identity of a user. There are a variety of authentication methods that can be used, including:

  • Multi-factor authentication (MFA): MFA requires users to provide two or more different factors of authentication, such as a password and a fingerprint scan.
  • Biometric authentication: Biometric authentication uses unique physical characteristics, such as fingerprints or facial features, to identify users.
  • Tokens: Tokens are physical devices that generate a one-time password or other authentication code that can be used to authenticate users.

  The strength of an authentication method depends on the number of factors that are used and the uniqueness of those factors. MFA is generally considered to be more secure than single-factor authentication because it requires users to provide multiple different pieces of evidence to prove their identity.

  Biometric authentication is also considered to be very secure because it is difficult to forge or steal biometric data. However, biometric authentication can be more expensive and difficult to implement than other authentication methods.

  Tokens are a good option for organizations that need to provide strong authentication for remote users or users who do not have access to biometric authentication devices. The CompTIA Security+ Cheat Sheet covers the different types of authentication methods and their strengths and weaknesses.

  Access Control Models: RBAC, ABAC, DAC, MAC

  Access control models are used to define the rules for who can access what resources and under what conditions. There are a variety of access control models, including:

  • Role-based access control (RBAC): RBAC assigns users to roles, and each role is granted specific permissions. This makes it easy to manage access to resources because you can simply add or remove users from roles.
  • Attribute-based access control (ABAC): ABAC makes access decisions based on the attributes of the user, the resource, and the environment. This allows for more fine-grained access control than RBAC.
  • Discretionary access control (DAC): DAC gives users the ability to control who can access their resources. This is a simple access control model, but it can be difficult to manage in large organizations.
  • Mandatory access control (MAC): MAC is a more restrictive access control model that is often used in government and military organizations. MAC labels resources with a security classification, and users are only allowed to access resources that are at or below their security classification.

  The choice of which access control model to use depends on the specific needs of the organization. RBAC is a good choice for organizations that need to manage access to a large number of resources. ABAC is a good choice for organizations that need more fine-grained access control. DAC is a good choice for organizations that need to give users more control over their resources. MAC is a good choice for organizations that need to protect sensitive data. The CompTIA Security+ Cheat Sheet covers the different types of access control models and their strengths and weaknesses.

  Federation & SSO (Single Sign-On)

  Federation and single sign-on (SSO) are two related technologies that can be used to improve the security and usability of access to multiple applications.

  Federation is a process of creating a trust relationship between two or more organizations. Once a federation is established, users from one organization can access resources from another organization without having to log in separately.

  SSO is a technology that allows users to log in to multiple applications with a single set of credentials. This eliminates the need for users to remember multiple passwords and makes it easier for them to access the applications they need. Federation and SSO can be implemented using a variety of technologies, including SAML, OAuth, and OpenID Connect. The choice of technology depends on the specific needs of the organization.

  Increased usability: Federation and SSO can make it easier for users to access the applications they need by eliminating the need for them to log in to each application separately.
  Reduced costs: Federation and SSO can help to reduce costs by eliminating the need for organizations to maintain multiple sets of user credentials.

The CompTIA Security+ Cheat Sheet covers the basics of federation and SSO, including the benefits of these technologies and the different technologies that can be used to implement them.
