Study Notes
Cloud Computing and DevOps in IT Infrastructure
-
Cloud computing encompasses providing hosted services through the internet, with fundamental types being IaaS, PaaS, and SaaS.
-
Public clouds allow anyone to purchase services, while private clouds are limited to defined users with access rights.
-
Cloud computing aims to provide quick and scalable access to computer resources and IT services, whether private or public.
-
Cloud infrastructure components are required to implement cloud computing architecture correctly.
-
IaaS provides virtual server instances, storage, and APIs, with providers like Amazon Web Services.
-
PaaS offers development tools for applications, with options like Salesforce’s Lightning Platform and AWS Elastic Beanstalk.
-
SaaS delivers software applications over the internet, such as Microsoft 365 for productivity and email services.
-
Cloud computing deployment models include private clouds, public clouds, hybrid clouds, and multicloud approaches.
-
Hybrid clouds combine public and private cloud services for automation, scalability, and control over critical data.
-
Multicloud involves using various IaaS providers for reasons like risk reduction and competitive pricing.
-
DevOps tools like Git for source code management and Jira for issue tracking are essential in IT infrastructure.
-
DevOps lifecycle involves creating, storing, analyzing, and evaluating source code, with tools like Git and Jira being widely used in the software industry.
-
The CIA triad is a fundamental concept in information security, and its principles are violated in various security incidents.
-
Information security professionals evaluate risks and vulnerabilities based on the potential impact on confidentiality, integrity, and availability of an organization's assets.
-
Confidentiality: Information that should be private remains private and accessible only to authorized individuals.
-
safeguards: Cryptography and access restrictions.
-
Threats: poorly administered systems, insecure networks, intruders, social engineering.
-
Integrity: Prevents incorrect or unauthorized changes to information and its source or origin.
-
Preventative procedures: Access controls.
-
Detective procedures: Discover unapproved changes when preventive mechanisms fail.
-
Controls: Principle of least privilege, rotation of duties, separation of duties.
-
Availability: Information must be accessible to authorized users before confidentiality and integrity are considered.
-
Threats: Denial of Service (DoS) attacks, natural disasters, human errors.
-
Business continuity and disaster recovery planning are essential to maintain information availability.
-
Non-repudiation: Cryptographic digital signature that demonstrates the authenticity of a message or digital transaction.
-
Forms of non-repudiation: Approval, sending, origin, submission, transport, receipt, and knowledge.
-
Legal non-repudiation: Differentiated from information security non-repudiation in the legal sense.
-
Threats: Phishing attacks, Trojan horses, theft of confidential data.
