MOBILE & WIRELESS SECURITY And MOBILE & WIRELESS SECURITYDEEPAK948083
This document provides an overview of mobile and wireless security. It discusses the need for security as wireless networks become more prevalent and outlines some common security threats like spoofing, sniffing, tampering and theft. It then describes various security technologies used to address these threats, including cryptography, digital certificates, digital signatures and public key infrastructure. Specific security protocols like SSL, TLS and IPSec are also mentioned. The document emphasizes that securing wireless networks requires considering authentication, data integrity, confidentiality, authorization and non-repudiation across the entire environment.
Network security involves protecting networks from unauthorized access and risks. It is important for network administrators to take preventive measures to secure networks used by individuals, businesses, and governments. There are various types of network security devices that fulfill different functions like blocking surplus traffic (active devices), identifying unwanted traffic (passive devices), and scanning for potential problems (preventative devices). Firewalls are a key example of an active device that establishes a barrier between internal and external networks and regulates incoming and outgoing traffic.
Digital certificates are used to verify the identity of entities providing services over the internet and ensure secure communication. A digital certificate contains a public key, identity information, and has an expiration date. It is issued by a trusted certificate authority to validate the owner of a public key. When requests are made to a service, the recipient can verify the certificate to confirm the sender is authentic. Certificates help establish encrypted connections and trust in online transactions. Expired or stolen certificates still allow the thief to use the public key until the expiration date, so timely renewal and revocation is important for security.
The ability to conceal the contents of sensitive messages and to verify the contents of messages and the identities of their senders have the potential to be useful in all areas of business
- Security is a concept similar to being cautious
or alert against any danger. Network security is the condition of
being protected against any danger or loss. Thus safety plays a
important role in bank transactions where disclosure of any data
results in big loss. We can define networking as the combination
of two or more computers for the purpose of resource sharing.
Resources here include files, database, emails etc. It is the
protection of these resources from unauthorized users that
brought the development of network security. It is a measure
incorporated to protect data during their transmission and also
to ensure the transmitted is protected and authentic.
Security of online bank transactions here has been
improved by increasing the number of bits while establishing the
SSL connection as well as in RSA asymmetric key encryption
along with SHA1 used for digital signature to authenticate the
user
The document discusses Secure Socket Layer (SSL) protocol and how it provides security for internet transactions. It explains that SSL uses cryptography, digital signatures, and certificates to provide confidentiality, message integrity, and authentication. It details how SSL works, including the handshake protocol for authentication and key exchange, the record protocol for encrypting data transfer, and SSL roles/elements like certificates and certificate authorities. The goal of the project is to implement a client and server that can securely communicate and transfer data using the SSL protocol.

SSL and S-HTTP are the two key protocols for secure transactions on the web. SSL uses public key cryptography for server authentication and encryption of data transmitted between clients and servers. S-HTTP ensures confidentiality, authenticity, and non-repudiation of transactions. VPNs allow private networks to communicate confidentially over public networks like the internet. Firewalls define and control network access to protect organizations, ensuring data integrity, authentication, and confidentiality while preventing unauthorized access from outside the network. They can also block unsecured external access and limit internal users.
This document discusses security issues related to mobile technology. It begins by explaining the importance of understanding threats when building a security system. It then discusses different types of attacks like interception, modification, and interruption that can target both static and dynamic assets. The document also covers security concepts like confidentiality, integrity, authorization, and availability. It explains symmetric and asymmetric encryption techniques as well as protocols like SSL, TLS, and WTLS that use these techniques to securely transmit data over networks.

1. Cryptography is used to provide security in electronic commerce by ensuring privacy, authenticity, and preventing forgery, alteration, eavesdropping and tracing of messages.
2. There are two main types of cryptography - symmetric which uses the same key for encryption and decryption, and asymmetric (public key) which uses different keys for encryption and decryption.
3. Common symmetric algorithms are DES and AES while RSA is an example of an asymmetric algorithm commonly used for digital signatures and encryption.
E-commerce security has six main requirements: secrecy, authenticity, integrity, availability, un-refuseability, and privacy. The document provides examples of each requirement and discusses how cryptography/encryption works to provide secrecy through encrypting plain text into cipher text using keys. Symmetric-key cryptography uses a shared key for encryption and decryption while asymmetric key cryptography uses a public key for encryption and private key for decryption.

Types of Networks
There are different types of networks. Each type has different characteristics and
therefore different security needs. Some of the fundamental differentiating attributes of
the various types of networks are:
the physical distance the network spans
the topology of the network nodes
the types of media used for communication between nodes in the network
the different devices supported on the network
the different applications supported on the network
the different groups of users permitted on the network
the different protocols supported on each network
Depending on the type of network there may be different information security
requirements requiring that various protocols, security services, security mechanisms are
used in a fashion to support that type of network.
While each network environment has some characteristics and security needs unique to
that environment, there are many security techniques that should be universally applied to
all environments. For example; sound policies and procedures, risk assessment of the
assets, user awareness training, encryption technology, authentication technology, sound
credential (password) selection and protection, malware protection, firewalls are a few
security techniques that need to be applied in all of the networks albeit in configurations
that best suits a particular environment.
Local Area Network (LAN)
A LAN network covers a small geographic area that takes advantage of high speed data
transfers usually implemented through Ethernet or fiber. A LAN could be a home, office,
group of building with local proximity (university, business). LANs typically share
resources such as file servers and printers.
Wide Area Network (WAN)
A WAN covers a large geographic area that may require connection through satellite,
high speed dedicated lines and other means. The internet is a WAN. WANs can connect
LANs together into a larger organizational structure that can be used to share resources
such as file, email, dns servers to name a few. Resources can be shared using slower
connections on geographically separated areas across the WAN.
Wireless Networks and Mobile Networks
The movement to laptop systems at home and workplaces accelerated the mobility of
computing.
As employees traveled between offices, client sites, home and various other remote
locations they could remain connected to company servers as long as the remote site had
connectivity to the companies’ intranet. Initially this connectivity was provided by
having Ethernet cabling available for remote users to physically plug their laptops into.
Eventually, companies started installing wireless hotspots that could be automatically
detected by systems that had wireless cards.
The proliferation of wireless connectivity and internet use spread from the workplace to

The document provides an overview of information technology and firewalls. It discusses what a firewall is, the history and types of firewalls, how firewalls work, the need for firewalls, advantages and disadvantages of firewalls, and real-time applications of firewalls. The types of firewalls discussed include packet filtering firewalls, stateful firewalls, application firewalls, and next generation firewalls. Examples are given of how firewalls can protect corporate networks, government organizations, service providers, small enterprises, home networks, and industrial control systems.
Decrypting web proxies allow enterprises to inspect encrypted traffic but undermine the security assumptions of TLS. While they can help detect threats, they break TLS authentication and confidentiality without all parties' consent. The legal and ethical implications are unclear. Full disclosure and user opt-in are recommended to balance security and privacy concerns.

Understanding User Needs and Satisfying ThemAggregage
https://www.productmanagementtoday.com/frs/26903918/understanding-user-needs-and-satisfying-them
We know we want to create products which our customers find to be valuable. Whether we label it as customer-centric or product-led depends on how long we've been doing product management. There are three challenges we face when doing this. The obvious challenge is figuring out what our users need; the non-obvious challenges are in creating a shared understanding of those needs and in sensing if what we're doing is meeting those needs.
In this webinar, we won't focus on the research methods for discovering user-needs. We will focus on synthesis of the needs we discover, communication and alignment tools, and how we operationalize addressing those needs.
Industry expert Scott Sehlhorst will:
• Introduce a taxonomy for user goals with real world examples
• Present the Onion Diagram, a tool for contextualizing task-level goals
• Illustrate how customer journey maps capture activity-level and task-level goals
• Demonstrate the best approach to selection and prioritization of user-goals to address
• Highlight the crucial benchmarks, observable changes, in ensuring fulfillment of customer needs

These platforms offer a variety of content, including movies, TV shows, and original productions, allowing users to access content on-demand across multiple devices.The historical context covers the early days of streaming, starting with Netflix's inception in 1997 as a DVD rental service and its transition to streaming in 2007. The presentation also highlights India's television journey, from the launch of Doordarshan in 1959 to the introduction of Direct-to-Home (DTH) satellite television in 2000, which expanded viewing choices and set the stage for the rise of OTT platforms like Big Flix, Ditto TV, Sony LIV, Hotstar, and Netflix. The business models of OTT platforms are explored in detail. Subscription Video on Demand (SVOD) models, exemplified by Netflix and Amazon Prime Video, offer unlimited content access for a monthly fee. Transactional Video on Demand (TVOD) models, like iTunes and Sky Box Office, allow users to pay for individual pieces of content. Advertising-Based Video on Demand (AVOD) models, such as YouTube and Facebook Watch, provide free content supported by advertisements. Hybrid models combine elements of SVOD and AVOD, offering flexibility to cater to diverse audience preferences.
Content acquisition strategies are also discussed, highlighting the dual approach of purchasing broadcasting rights for existing films and TV shows and investing in original content production. This section underscores the importance of a robust content library in attracting and retaining subscribers.The presentation addresses the challenges faced by OTT platforms, including the unpredictability of content acquisition and audience preferences. It emphasizes the difficulty of balancing content investment with returns in a competitive market, the high costs associated with marketing, and the need for continuous innovation and adaptation to stay relevant.
The impact of OTT platforms on the Bollywood film industry is significant. The competition for viewers has led to a decrease in cinema ticket sales, affecting the revenue of Bollywood films that traditionally rely on theatrical releases. Additionally, OTT platforms now pay less for film rights due to the uncertain success of films in cinemas.
Looking ahead, the future of OTT in India appears promising. The market is expected to grow by 20% annually, reaching a value of ₹1200 billion by the end of the decade. The increasing availability of affordable smartphones and internet access will drive this growth, making OTT platforms a primary source of entertainment for many viewers.

As a business owner, I understand the importance of having a strong online presence and leveraging various digital platforms to reach and engage with your target audience. One often overlooked yet highly valuable asset in this regard is the humble Yahoo account. While many may perceive Yahoo as a relic of the past, the truth is that these accounts still hold immense potential for businesses of all sizes.
1. Digital Certificate
Digital certificate is issued by a trusted third party which proves sender’s identity to the
receiver and receiver’s identity to the sender.
A digital certificate is a certificate issued by a Certificate Authority (CA) to verify the
identity of the certificate holder. The CA issues an encrypted digital certificate containing
the applicant’s public key and a variety of other identification information. Digital
certificate is used to attach public key with a particular individual or an entity.
Digital certificate contains:- The authenticity
1. Name of certificate holder.
2. Serial number which is used to uniquely identify a certificate, the individual or the
entity identified by the certificate
3. Expiration dates.
4. Copy of certificate holder’s public key.(used for decrypting messages and digital
signatures)
5. Digital Signature of the certificate issuing authority.
Digital certificate is also sent with the digital signature and the message.
Digital certificate vs digital signature :
Digital signature is used to verify authenticity, integrity, non-repudiation ,i.e. it is assuring that
the message is sent by the known user and not modified, while digital certificate is used to
verify the identity of the user, maybe sender or receiver. Thus, digital signature and certificate
are different kind of things but both are used for security. Most websites use digital certificate
to enhance trust of their users
2. Feature Digital Signature Digital Certificate
Basics /
Definition
Digital signature is like a fingerprint or an
attachment to a digital document that ensures
its authenticity and integrity.
Digital certificate is a file that ensures holder’s
identity and provides security.
Process / Steps
Hashed value of original message is encrypted
with sender’s secret key to generate the digital
signature.
It is generated by CA (Certifying Authority) that
involves four steps: Key Generation, Registration,
Verification, Creation.
Security
Services
Authenticity of Sender, integrity of the
document and non-repudiation.
It provides security and authenticity of
certificate holder.
Standard It follows Digital Signature Standard (DSS). It follows X.509 Standard Format
3. Public key– Key which is known to everyone. Ex-public key of A is 7, this information
is known to everyone.
Private key– Key which is only known to the person who’s private key it is.
Digital Signature
A digital signature is a mathematical technique used to validate the authenticity and
integrity of a message, software, or digital document.
Digital signature is electronic signatures, which assure that the message was sent by
a particular sender. While performing digital transactions authenticity and integrity
should be assured, otherwise, the data can be altered or someone can also act as if
he was the sender and expect a reply
4. Types of Internet Security Protocols
In today’s world, we transfer the data in bulk, and the security of this data is very important,
so Internet security provides that feature i.e., protection of data. There are different types of
protocol exist like routing, mail transfer, and remote communication protocol. But the Internet
security protocol helps in the security and integrity of data over the internet. There are many
protocols that exist that help in the security of data over the internet such as Secure Socket
Layer (SSL), Transport Layer Security (TLS).
SSL Protocol :
•SSL Protocol stands for Secure Sockets Layer protocol, which is an encryption-based
Internet security protocol that protects confidentiality and integrity of data.
•SSL is used to ensure the privacy and authenticity of data over the internet.
•SSL is located between the application and transport layers.
•At first, SSL contained security flaws and was quickly replaced by the first version of
TLS that’s why SSL is the predecessor of the modern TLS encryption.
•TLS/SSL website has “HTTPS” in its URL rather than “HTTP”.
•SSL is divided into three sub-protocols: the Handshake Protocol, the Record
Protocol, and the Alert Protocol.
5. TLS Protocol :
•Same as SSL, TLS which stands for Transport Layer Security is widely used for the
privacy and security of data over the internet.
•TLS uses a pseudo-random algorithm to generate the master secret which is a key
used for the encryption between the protocol client and protocol server.
•TLS is basically used for encrypting communication between online servers like a
web browser loading a web page in the online server.
•TLS also has three sub-protocols the same as SSL protocol – Handshake Protocol,
Record Protocol, and Alert Protocol.
SHTTP :
•SHTTP stands for Secure HyperText Transfer Protocol, which is a collection of
security measures like Establishing strong passwords, setting up a firewall, thinking
of antivirus protection, and so on designed to secure internet communication.
•SHTTP includes data entry forms that are used to input data, which has previously
been collected into a database. As well as internet-based transactions.
•SHTTP’s services are quite comparable to those of the SSL protocol.
•Secure HyperText Transfer Protocol works at the application layer (that defines the
shared communications protocols and interface methods used by hosts in a network)
and is thus closely linked with HTTP.
•SHTTP can authenticate and encrypt HTTP traffic between the client and the server.
•SHTTP operates on a message-by-message basis. It can encrypt and sign individual
messages.
6. Types of Firewalls in Network Security
Nowadays, protecting our sensitive data from unauthorized and unwanted sources has
become a significant challenge. There are numerous tools available that can provide various
levels of security and aid in the protection of private information stored in any system. A
‘firewall’ is a network security mechanism that protects our systems and data against
unauthorized access.
A firewall is a cybersecurity device or software application that filters network traffic. A
firewall acts as a traffic cop at your computer’s port. A fundamental purpose of a firewall
is to create a barrier that separates an internal network from incoming external traffic to
block malicious traffic requests and data packets, such as malware and hacking while
allowing legitimate traffic to pass through. A firewall enables only the traffic that has
been configured to accept, like IP addresses. It differentiates between legitimate and
malicious traffic and allows or blocks specific data packets based on predefined security
rules.
7. A Firewall is a necessary component of a company’s overall cybersecurity strategy. Most
computers have an in-built firewall, but it isn’t always the best option for security. What
can a firewall do to keep us safe?
It guards computers against unauthorized access.
It blocks unwanted content.
It provides a secure network when multiple people interact at the same time.
It prevents ransomware from spreading.
It protects private information, such as online banking credentials.
Types of Network Firewall :
Packet Filters –
It is a technique used to control network access by monitoring outgoing and incoming
packets and allowing them to pass or halt based on the source and destination Internet
Protocol (IP) addresses, protocols, and ports. This firewall is also known as a static
firewall.
Stateful Inspection Firewalls –
It is also a type of packet filtering which is used to control how data packets move
through a firewall. It is also called dynamic packet filtering. These firewalls can inspect
that if the packet belongs to a particular session or not. It only permits communication if
and only if, the session is perfectly established between two endpoints else it will block
the communication.
8. Application Layer Firewalls –
These firewalls can examine application layer (of OSI model) information like an HTTP
request. If finds some suspicious application that can be responsible for harming our
network or that is not safe for our network then it gets blocked right away.
Next-generation Firewalls –
These firewalls are called intelligent firewalls. These firewalls can perform all the tasks that
are performed by the other types of firewalls that we learned previously but on top of that, it
includes additional features like application awareness and control, integrated intrusion
prevention, and cloud-delivered threat intelligence.
Circuit-level gateways –
A circuit-level gateway is a firewall that provides User Datagram Protocol (UDP) and
Transmission Control Protocol (TCP) connection security and works between an Open
Systems Interconnection (OSI) network model’s transport and application layers such
as the session layer.
9. Software Firewall –
The software firewall is a type of computer software that runs on our computers. It protects
our system from any external attacks such as unauthorized access, malicious attacks, etc. by
notifying us about the danger that can occur if we open a particular mail or if we try to open
a website that is not secure.
Hardware Firewall –
A hardware firewall is a physical appliance that is deployed to enforce a network boundary.
All network links crossing this boundary pass-through this firewall, which enables it to
perform an inspection of both inbound and outbound network traffic and enforce access
controls and other security policies.
Cloud Firewall –
These are software-based, cloud-deployed network devices. This cloud-based firewall
protects a private network from any unwanted access. Unlike traditional firewalls, a cloud
firewall filters data at the cloud level.
