Which protocol would be used to provide security?

SSL – A Secure Socket Layer (SSL) is a network security protocol primarily used for ensuring secure internet connections and protecting sensitive data. This protocol can allow for server/client communication as well as server/server communication.

Which 128bit block cipher encryption algorithm does the US government use to protect classified information?

The Advanced Encryption Standard (AES) is a symmetric block cipher chosen by the U.S. government to protect classified information. AES is implemented in software and hardware throughout the world to encrypt sensitive data. It is essential for government computer security, cybersecurity and electronic data protection.

What principles help you ensure high availability?

Reliability engineering uses three principles of systems design to help achieve high availability: elimination of single-points-of-failure; reliable crossover or failover points; and failure detection capabilities.

Which data is maintained in NAS and SAN services?

Which data state is maintained in NAS and SAN services? stored data data in-transit encrypted data data in-process Explanation: A cybersecurity specialist must be familiar with the types of technologies used to store, transmit, and process data.

Which of the following are categories of security measures or controls?

There are three primary areas or classifications of security controls. These include management security, operational security, and physical security controls.

What three methods help to ensure system availability choose three?

eliminate single points of failure.
provide for reliable crossover.
ensure confidentiality.
check for data consistency.
use encryption.
detect failures as they occur. Explanation:

What are security procedures?

A security procedure is a set sequence of necessary activities that performs a specific security task or function. … Procedures provide a starting point for implementing the consistency needed to decrease variation in security processes, which increases control of security within the organization.

What is a security protocol and what is its purpose?

A security protocol is a type of communication protocol combined with cryptographic mechanisms, i.e. it specifies sequence and formats for exchanging messages including cryptographic elements between two or more parties.

What are the 3 types of access control?

Three main types of access control systems are: Discretionary Access Control (DAC), Role Based Access Control (RBAC), and Mandatory Access Control (MAC).

What is security access control systems?

Access control is a security technique that regulates who or what can view or use resources in a computing environment. It is a fundamental concept in security that minimizes risk to the business or organization. … Logical access control limits connections to computer networks, system files and data.

What are the various access controls available to security professionals?

Mandatory access control (MAC). …
Discretionary access control (DAC). …
Role-based access control (RBAC). …
Rule-based access control. …
Attribute-based access control (ABAC).

What is AES cryptography?

The Advanced Encryption Standard (AES), also known by its original name Rijndael (Dutch pronunciation: [ˈrɛindaːl]), is a specification for the encryption of electronic data established by the U.S. National Institute of Standards and Technology (NIST) in 2001.

What is AES 256 encryption algorithm?

The AES Encryption algorithm (also known as the Rijndael algorithm) is a symmetric block cipher algorithm with a block/chunk size of 128 bits. It converts these individual blocks using keys of 128, 192, and 256 bits. Once it encrypts these blocks, it joins them together to form the ciphertext.

Where is AES encryption used?

The National Security Agency (NSA) and many other U.S. government entities, including the military, use AES encryption for encrypted communications and secure data storage daily. LastPass, a password management service, uses AES encryption to keep its users’ passwords safe from hackers and even LastPass employees.

Which protocol would be used to provide security for employees that access systems remotely from home?

A VPN encrypts all of your internet traffic, making it unreadable to anyone who intercepts it. Make sure employees exclusively use the VPN when working and when accessing company information systems remotely.

Which of the following are states of data?

The three states of data are data at rest, data in motion and data in use.
