Overview of the CompTIA SY0-701 Exam

The CompTIA Security+ (SY0-701) exam is a globally recognized certification that validates your foundational skills in cybersecurity. It is designed for IT professionals who have at least two years of experience in IT administration with a focus on security. The exam covers a wide range of topics, including:

  • Threats, Attacks, and Vulnerabilities
  • Technologies and Tools
  • Architecture and Design
  • Identity and Access Management
  • Risk Management
  • Cryptography and PKI (Public Key Infrastructure)

The exam consists of a maximum of 90 questions, including multiple-choice and performance-based questions, and you have 90 minutes to complete it. A passing score is 750 on a scale of 100-900.

What is AES Encryption?

AES, or Advanced Encryption Standard, is a symmetric encryption algorithm widely used to secure sensitive data. It was established by the U.S. National Institute of Standards and Technology (NIST) in 2001 and has since become the gold standard for encryption. AES operates on fixed block sizes of 128 bits and supports key lengths of 128, 192, and 256 bits. The algorithm is known for its speed and security, making it ideal for both hardware and software implementations.

How AES Works

AES encryption involves several rounds of processing, including substitution, permutation, and mixing of the input plaintext to produce the final ciphertext. The number of rounds depends on the key length:

  • 128-bit key: 10 rounds
  • 192-bit key: 12 rounds
  • 256-bit key: 14 rounds

Each round consists of four main steps:

1. SubBytes: A non-linear substitution step where each byte is replaced with another according to a lookup table.

2. ShiftRows: A transposition step where the last three rows of the state are shifted cyclically.

3. MixColumns: A mixing operation that operates on the columns of the state, combining the four bytes in each column.

4. AddRoundKey: Each byte of the state is combined with a round key using the XOR operation.

AES is widely used in various applications, including securing sensitive data in databases, encrypting files, and protecting communications over the internet.

Authentication Methods That Use AES

AES encryption plays a crucial role in various authentication methods, ensuring that data remains secure during transmission and storage. Below are some of the most common authentication methods that utilize AES encryption:

Kerberos

Kerberos is a network authentication protocol that uses symmetric-key cryptography to provide strong authentication for client-server applications. It relies on AES encryption to secure tickets that are used to authenticate users and services within a network. Kerberos is widely used in enterprise environments, particularly in Microsoft Windows Active Directory.

WPA2 and WPA3 (Wi-Fi Protected Access)

WPA2 and WPA3 are security protocols designed to secure wireless networks. Both protocols use AES encryption to protect data transmitted over Wi-Fi networks. WPA2, introduced in 2004, became the industry standard for Wi-Fi security, while WPA3, released in 2018, offers enhanced security features, including stronger encryption and protection against brute-force attacks.

Microsoft NTLMv2 (New Technology LAN Manager version 2)

NTLMv2 is a challenge-response authentication protocol used in Microsoft Windows environments. It uses AES encryption to secure the authentication process, making it more resistant to various types of attacks compared to its predecessor, NTLMv1. NTLMv2 is commonly used in environments where Kerberos is not available.

RADIUS (Remote Authentication Dial-In User Service)

RADIUS is a networking protocol that provides centralized authentication, authorization, and accounting (AAA) management for users who connect and use a network service. RADIUS servers often use AES encryption to secure the communication between the RADIUS client and server, ensuring that sensitive information, such as passwords, is protected during transmission.
