Q3A
Q4BA white hat (or a white hat hacker) is an ethical computer hacker, or a computer security expert, who focuses on
penetration testing and in other testing methodologies that ensures the safety of an organization\’s information systems.
Ethical hacking may be a term meant to imply a broader category than simply penetration testing. Contrasted with black
hat, a malicious hacker, the name comes from Western films, where heroic and antagonistic cowboys might traditionally
wear a white and a black hat respectively. While a white hat hacker hacks under good intentions with permission, and a
black hat hacker, most frequently unauthorized, has malicious intent, there\’s a 3rd kind referred to as a gray hat hacker
who hacks with good intentions but sometimes without permission.White hat hackers can also add teams called
“sneakers and/or hacker clubs”,red teams, or tiger teams.While penetration testing concentrates on attacking software
and computer systems from the beginning ?scanning ports, examining known defects in protocols and applications
running on the system and patch installations, as an example ?ethical hacking may include other things. A full-blown
ethical hack might include emailing staff to invite password details, searching through executive\’s dustbins and
typically breaking and entering, without the knowledge and consent of the targets. Only the owners, CEOs and Board
Members (stake holders) who asked for such a censoring of this magnitude are aware. to undertake to duplicate a
number of the destructive techniques a true attack might employ, ethical hackers may arrange for cloned test systems,
or organize a hack late in the dark while systems are less critical. In most up-to-date cases these hacks perpetuate for
the long-term con (days, if not weeks, of long-term human infiltration into an organization). Some examples include
leaving USB/flash key drives with hidden auto-start software during a public area as if someone lost the tiny drive and
an unsuspecting employee found it and took it.Some other methods of completing these include:?DoS attacks?Social
engineering tactics?Reverse engineering? Network security?Disk and memory forensics?Vulnerability
research?Security scanners such as:?W3af?Nessus?Burp suite? Frameworks such as:?Metasploit?Training
PlatformsThese methods identify and exploit known security vulnerabilities and plan to evade security to realize entry
into secured areas. they\’re ready to do that by hiding software and system back-doors\\’ which will be used as a link to information or access that a non-ethical hacker, also referred to asblack-hat\’ or `grey-hat\’, might want to succeed in Exam E

Q10AThe AndroidManifest.xml file contains information about your package, including components of the appliance like activities, services, broadcast receivers, content providers, etc. It performs other tasks also:?it\’s responsible to guard the appliance to access any protected parts by providing the permissions.
It also declares the android API that the appliance goes to use.
It lists the instrumentation classes.

The instrumentation classes provide profiling and other information. This information is removed just before the appliance is published etc. This is the specified XML file for all the android applications and is located inside the basis directory.
Q11DAt this stage exploiting a vulnerability to execute code on the victim\’s direct channel for remote manipulation of the victim is the objective. Here ancient hardening measures add resiliency, however, custom defense capabilities are necessary to prevent zero-day exploits at this stage. once the weapon is delivered to the victim host, exploitation triggers intruders\’ code. Most often, exploitation targets Associate in the Nursing application or software vulnerability, however it may additionally additional merely exploit the users themselves or leverage Associate in Nursing software feature that auto-
executes code. In recent years this has become a district of experience within the hacking community that is commonly incontestible at events like Blackhat, Defcon, and also the like.
Q12AVoIP (Voice over Internet Protocol) is a web convention that permits the transmission of voice brings over the web. It does as such by changing over the ordinary telephone signals into advanced signs. Virtual Private Networks(VPN) give a protected association with an association \’ organization. Along these lines, VoIP traffic can disregard an SSL-based VPN, successfully scrambling VoIP administrations. When leading surveillance, in the underlying phases of VoIP
footprinting, the accompanying freely accessible data can be normal: All open ports and administrations of the gadgets associated with the VoIP organization The public VoIP worker’s IP address The working arrangement of the worker
running VoIP The organization framework
