  • Determine why a penetration test and its associated tasks are necessary. (correct)
  • Perform the attack and measure the results.
  • Research applicable state and federal regulations that apply to the proposed tests.
  • Report the results of the attack to the organization.

    Study Notes

    Ethical Hacking Basics

    • Ethical hackers adhere to a strict code of ethics, distinguishing them from malicious hackers.
    • Breaking client trust can undermine the accuracy of testing results and lead to further complications in the engagement.
    • The planning phase of a penetration test should clarify the necessity of the test and its associated tasks.

    Penetration Testing Approaches

    • Ethical hacking steps include planning, discovery, attack, and reporting.
    • Black-box testing simulates an attacker’s perspective, assessing systems without inside knowledge.
    • Physical attacks can target equipment, facilities, or involve social engineering threats.

    Risk Management and Controls

    • Controls in risk mitigation include administrative, technical, and physical measures; distribution is not a recognized control type.
    • An exploit refers to software or techniques that target system vulnerabilities.

    Cryptography and Security Measures

    • Domain Name Service (DNS) translates IP addresses to domain names.
    • The deny-all principle restricts access to only what is necessary.
    • Digital certificates serve as a means of identification and ensure secure transactions online.

    Hashing and Encryption

    • A hash collision occurs when two different inputs yield the same hash value.
    • Hashing functions are easy to compute one way but difficult to reverse; this is known as trapdoor functions in asymmetric encryption.
    • Symmetric encryption uses the same key for encryption and decryption, while asymmetric encryption involves a key pair (public and private keys).

    Certificate Authorities and Digital Signatures

    • Certificate Authorities (CAs) generate key pairs and bind identities to public keys, crucial for secure communications.
    • To create a digital signature, the original message is hashed to ensure integrity; this hash verifies that information is unaltered.

    Password Attacks

    • Common password attack methods include brute-force, which tests all possible combinations, and dictionary attacks, which utilize predefined lists of words.
    • Social engineering involves manipulating individuals into divulging confidential information.
