Wireless communication involves the transmission of information over a distance without the help of wires, cables or any other forms of electrical conductors.
Wireless communication is a broad term that incorporates all procedures and forms of connecting and communicating between two or more devices using a wireless signal through wireless communication technologies and devices.
Features of Wireless Communication
The evolution of wireless technology has brought many advancements with its effective features.
The transmitted distance can be anywhere between a few meters (for example, a television's remote control) and thousands of kilometers (for example, radio communication).
Wireless communication can be used for cellular telephony, wireless access to the internet, wireless home networking, and so on.

# Internet Security: Safeguarding Your Digital World
In the contemporary digital age, the internet is a cornerstone of our daily lives. It connects us to vast amounts of information, provides platforms for communication, enables commerce, and offers endless entertainment. However, with these conveniences come significant security challenges. Internet security is essential to protect our digital identities, sensitive data, and overall online experience. This comprehensive guide explores the multifaceted world of internet security, providing insights into its importance, common threats, and effective strategies to safeguard your digital world.
## Understanding Internet Security
Internet security encompasses the measures and protocols used to protect information, devices, and networks from unauthorized access, attacks, and damage. It involves a wide range of practices designed to safeguard data confidentiality, integrity, and availability. Effective internet security is crucial for individuals, businesses, and governments alike, as cyber threats continue to evolve in complexity and scale.
### Key Components of Internet Security
1. **Confidentiality**: Ensuring that information is accessible only to those authorized to access it.
2. **Integrity**: Protecting information from being altered or tampered with by unauthorized parties.
3. **Availability**: Ensuring that authorized users have reliable access to information and resources when needed.
## Common Internet Security Threats
Cyber threats are numerous and constantly evolving. Understanding these threats is the first step in protecting against them. Some of the most common internet security threats include:
### Malware
Malware, or malicious software, is designed to harm, exploit, or otherwise compromise a device, network, or service. Common types of malware include:
- **Viruses**: Programs that attach themselves to legitimate software and replicate, spreading to other programs and files.
- **Worms**: Standalone malware that replicates itself to spread to other computers.
- **Trojan Horses**: Malicious software disguised as legitimate software.
- **Ransomware**: Malware that encrypts a user's files and demands a ransom for the decryption key.
- **Spyware**: Software that secretly monitors and collects user information.
### Phishing
Phishing is a social engineering attack that aims to steal sensitive information such as usernames, passwords, and credit card details. Attackers often masquerade as trusted entities in email or other communication channels, tricking victims into providing their information.
### Man-in-the-Middle (MitM) Attacks
MitM attacks occur when an attacker intercepts and potentially alters communication between two parties without their knowledge. This can lead to the unauthorized acquisition of sensitive information.
### Denial-of-Service (DoS) and Distributed Denial-of-Service (DDoS) Attacks
2. INTRODUCTIONINTRODUCTION
Cloud Computing provides us a means by which
we can access the applications as utilities, over
the Internet. It allows us to create, configure, and
customize applications online.
With Cloud Computing users can access database
resources via the internet from anywhere for as
long as they need without worrying about any
maintenance or management of actual resources.
3. What is Cloud?What is Cloud?
The term Cloud refers to a Network or Internet.
In other words, we can say that Cloud is something,
which is present at remote location.
Cloud can provide services over network, i.e.,
on public networks or on private networks, i.e.,
WAN, LAN or VPN.
Applications such as e-mail, web conferencing,
customer relationship management (CRM),
all run in cloud.
4. What is Cloud Computing?What is Cloud Computing?
Cloud Computing refers to manipulating,
configuring, and accessing the applications online.
It offers online data storage, infrastructure and application.
Cloud Computing is both a combination of software and
hardware based computing resources delivered as a
network service.
6. Basic ConceptsBasic Concepts
There are certain services and models working behind the
scene making the cloud computing feasible and accessible
to end users. Following are the working models for cloud
computing:
1. Deployment Models1. Deployment Models
2. Service Models2. Service Models
7. Deployment ModelsDeployment Models
Deployment models define the type of access to the
cloud, i.e., how the cloud is located? Cloud can have any
of the four types of access: Public, Private, Hybrid and
Community.
8.
9. PUBLIC CLOUDPUBLIC CLOUD : The Public Cloud allows systems and services to be
easily accessible to the general public. Public cloud may be less secure because
of its openness, e.g., e-mail.
PRIVATE CLOUDPRIVATE CLOUD : The Private Cloud allows systems and services to be
accessible within an organization. It offers increased security because of its
private nature.
COMMUNITY CLOUDCOMMUNITY CLOUD : The Community Cloud allows systems and
services to be accessible by group of organizations.
HYBRID CLOUDHYBRID CLOUD : The Hybrid Cloud is mixture of public and private
cloud. However, the critical activities are performed using private cloud while
the non-critical activities are performed using public cloud.
10. Service ModelsService Models
Service Models are the reference models on which the
Cloud Computing is based. These can be categorized
into three basic service models as listed below:
11. 1.1.Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
2. Platform as a Service (PaaS)2. Platform as a Service (PaaS)
3. Software as a Service (SaaS)3. Software as a Service (SaaS)
12. Infrastructure as a Service (IaaS)Infrastructure as a Service (IaaS)
IaaS is the delivery of technology infrastructure as an on
demand scalable service.
IaaS provides access to fundamental resources such as
physical machines, virtual machines, virtual storage, etc.
•Usually billed based on usage
•Usually multi tenant virtualized environment
•Can be coupled with Managed Services for OS and
application support
14. Platform as a Service (PaaS)Platform as a Service (PaaS)
PaaS provides the runtime environment for applications,
development & deployment tools, etc.
PaaS provides all of the facilities required to support the
complete life cycle of building and delivering web
applications and services entirely from the Internet.
Typically applications must be developed with a particular
platform in mind
•Multi tenant environments
•Highly scalable multi tier architecture
16. Software as a Service (SaaS)Software as a Service (SaaS)
SaaS model allows to use software applications as a service
to end users.
SaaS is a software delivery methodology that provides
licensed multi-tenant access to software and its functions
remotely as a Web-based service.
• Usually billed based on usage
• Usually multi tenant environment
• Highly scalable architecture
20. DisadvantagesDisadvantages
• Requires a constant Internet connection
• Does not work well with low-speed connections
• Features might be limited
• Can be slow
• Stored data can be lost
• Stored data might not be secure
21. Cloud StorageCloud Storage
• Create an Account
User name and
password.
• Content lives with the
account in the cloud.
• Log onto any
computer with Wi-Fi
to find your content
22. Download For StorageDownload For Storage
• Download a cloud based app to on your computer
• The app lives on your Computer
• Save files to the app
• When connected to the Internet it will sync with the cloud
• The Cloud can be accessed from any Internet connection
