1. What are the main benefits and challenges of cloud computing for

security? Explain with examples.

- Benefits: Cloud computing can provide scalability, flexibility, costefficiency, and reliability for security. For example, cloud services can offer

on-demand access to security resources, such as encryption, firewalls, or

intrusion detection systems, without requiring upfront investment or

maintenance. Cloud services can also enable rapid recovery from disasters or

cyberattacks by using backup and replication mechanisms across multiple

locations.

- Challenges: Cloud computing can also introduce new risks and

vulnerabilities for security. For example, cloud users may lose control and

visibility over their data and applications, as they are stored and processed by

third-party providers. Cloud users may also face legal and regulatory issues,

such as compliance with data protection laws or jurisdictional disputes.

Cloud users may also have to deal with shared responsibility models, where

they have to coordinate with cloud providers and other users to ensure

security.

2. What are some of the best practices for securing cloud data? Explain with

examples.

- Some of the best practices for securing cloud data are:

 - Encrypting data at rest and in transit, using strong algorithms and keys, to

protect data from unauthorized access or modification. For example, using

AES-256 or RSA-2048 for encryption, and storing keys in secure hardware

modules or vaults.

 - Implementing access control policies and mechanisms, such as

authentication, authorization, auditing, and logging, to restrict and monitor

data access and usage. For example, using multi-factor authentication, role-
