The ISO 27001 and ISO 27002 standards are important for the information systems security (ISS) practitioner because they:

ISO 27001 and ISO 27002 do not specifically ensure compliance with PCI DSS, which is a separate standard focused on payment card security. While implementing ISO standards can enhance overall security practices, they do not directly mandate adherence to PCI DSS requirements, which are tailored specifically for payment card transactions.

While ISO 27001 and ISO 27002 are indeed significant, they specifically focus on information security rather than the broader scope of information technology management. Other standards exist that address IT management practices, but ISO 27001 and ISO 27002 are specifically tailored for information security.

These ISO standards do not ensure compliance with the Advanced Encryption Standard (AES). AES is a cryptographic standard for securing data, while ISO 27001 and ISO 27002 provide guidelines for a broader information security management framework, which may include encryption but does not guarantee compliance with specific encryption standards.
