Ans. 1 – Mobile Networks and Wireless we have two common method to using the internet
in daily life. Wireless networks provides fast and reliable network connectivity. There are
some attacks that an attacker try in mobile and the wireless connection, here we are
discussing two common attacks that are below –
 SMiShing – It is common use attack, in this user get a sms of a fraud message or
links. When a user an open that link it will reflect to the website where attacker try to
get information of the user. It also happen after clicking link a malware can be
download in your device and steal your data. You can protect yourself by these kind
of attacks, you should never click on links which you don’t about it and should report
on the link. If you see it is send by an orgazition you can complaint about of the sms.
 Rouge Wireless Device – Rouge wireless device and access point is the unauthorized
wireless device that added in the network these are not managed by the network
admins it can be gateway of attacker. If an attacker have direct access to AP or
network a malicious attack can be done by attacker. The solution of this attack is you
need to implement authentication process and network control list, after that you have
full control of securing your network.
Ans. 2 – Vulnerability you can refer as a weakness of any system or infrastructure where any
attacker can attack on the devices. Now will discuss two examples of multimedia
vulnerabilities.

 VOIP – In Voice over ip you have multiple types of vulnerabilities the data
verification cannot done this can be cause of the man in the middle attack. You have
low resources in the embedded so that is an attacker point. The next point is resources
should be secure on every side it can be os or platform also. Physical connectivity or
collision of packet need to be manage.
 Streaming Services – In today’s world most of user are using the service of
streaming, YouTube is great example you can see so it very important to secure the
user data. First of all the user authentication and authorization must be highly
protected and in other hand both client and server should uses the encryption method.
URL video and the video files that also be encrypted these methods can secure our
video streaming methods.
Ans. 3 - Diffie-Hellman key exchange process – This algorithm shared a secret key that can
be used for the secure communication on the public network, it used the elliptic curve to
generate points and will get a secret key using parameters.

Above picture show how the key is generated in this you can see how keys are exchanging
and a Calculation done to generate that.
Ans. 4 – Client Side Attack –
 Client side attack where username, password, cookies, session management and other
information can be steal. Attacker can create fake links and website and try them to
attack with client.
 Content Spoofing – In this attacker create a fake website or send a mail to user to steal
the information. Their attacker create a same original website and mail user so the
user can trust and enter his personal information like bank accounts and credit card
information, after stealing attacker sell their data and shut his own website.
 Cross site scripting – In this a malicious code is run in the user browser which can be
written in any language like java, these codes are already attached on some website
one user open the website these code are executed automatically, you need to always
check the website should be open as https which is secure.
Server Side Attack –
 These kinds of attack on the web server for viewing or downloading file with
authorization.
 Path Traversal Attack – Web server are only allowed the web document root
directory, in this attacker access the files outside the allowed directory.
 DOD Attack – Denial of service attack here attacker launch multiple websites and
message boards, this attack is complex to resolve. High speed packets arrived here
that can be a cause of find the issue.
 SQL Injection - Attacker try to attack in form of the SQL query.

Ans. 5 – We have multiple mechanism that makes our web connection secure, lets discuss
one by one below –
 HTTPS – Hypertext transfer protocol secure, it uses the encryption so it is secure, and
SSL are used for sending data. In that SSL all information are stored it is a certificate
that tells the complete details of the website. It used the port no. 443, sender send first
data and checked the receiver is same where data to be send. It is safest protocol that
not attacked by the attacker.
 SSL – Secure Socket Layer that provides security between browser and server. This
method encrypt the link between the user and server so make the data is private and
not accessible by the attacker. SSL has four protocol’s (record protocol, alert protocol,
handshake protocol and change cipher spec protocol). ...
