3D Touch

Force touch technology was not efficient in this upgrading world to resolve this problem 3D touch was introduced. Taking the Force Touch technology to an altogether new level, Apple launched 3D Touch on iPhone 6S and 6S Plus. Being more sensitive than Force Touch, 3D Touch has been developed to work using capacitive sensors integrated into the display.
Working-

In functionality, 3D Touch is really smart. It allows you to carry out certain tasks instantly through quick actions. It is generally essential for performing the tasks we intend to use most often. You don’t need to launch an app to carry out actions. As for instance, if you want to take a selfie, you don’t need to launch the Camera app. Simply light press on the Camera app, you get the option to Take Selfie right on your Homescreen.
Functionality for Peek and Pop-
In order to master 3D Touch, you need to understand Peek and Pop. While the former refers to a light press, the later is a hard press.
If you want to peek at a message, you just need to press it lightly. And, if you wish to pop into the message for a full view, you need to press it a little more deeply. That’s how it works!
Differentiating between Force Touch and 3D Touch-
Force Touch is smart enough to detect the pressure applied on the screen. It can detect not just multiple touches on the screen but can also calculate the difference in pressure on various points of the screen.
However, while reacting to your touch, Force Touch is not as fast as 3D Touch. The lightning fast response of the 3D Touch is because of the fusion of capacitive sensors and strain gauges. This fusion is perfected by the Taptic Engine.
The Future for Touch Technology-

Knowing the significance of how much 3D Touch has been appreciated by iPhone 6s users; touch technology is going to get a lot better in future. With the amazing ability to let iPhone owners use their device with more convenience and faster, it is here to stay.
Android smartphone makers are also working to provide 3D touch on their phones, currently, the Nougat version based smartphones are providing 3D Touch.

The Increasing Reach of Virtual Reality (VR)

Whats is Virtual Reality?

Virtual Reality (VR) is a technology that makes users feel in a Virtual Environment with the help of computing systems and specifically designed software.

The term “Virtual Reality “ itself is comprised of two words i.e. Virtual and Reality .Virtual means “not real” but “like real” and reality. Thus Virtual Reality means anything that is near to reality. Technically Virtual Reality is described as “a computer generated three dimensional environment” in which a person can interact or manipulate objects of such environment.
As Wikipedia states

Virtual reality or virtual realities (VR), also known as immersive multimedia or computer-simulated reality, is a computer technology that replicates an environment, real or imagined, and simulates a user’s physical presence and environment in a way that allows the user to interact with it. Virtual realities artificially create sensory experience, which can include sight, touch, hearing, and smell.

How Virtual Reality is achieved?

In Virtual Reality (VR) with the help of computer technology a simulated environmen
t is created in which the computer is transformed into a gatekeeper to an artificial world. Unlike usual graphic experienc
e instead of viewing a screen in front of users and keyboard or mouse for input, VR places the user inside that sim
ulated environment. Users can also interact within that given environment and manipulate objects in the virtual world with their sense such as hearing, touching and watching. There are a range of systems that are used for this purpose, such as headsets, Omni-directional treadmills and special gloves. These are used to actually stimulate our senses together in order to create the illusion of reality.

Following are the main components of a virtual environment:

1. The visual displays that immerse the user in the virtual world.
2. The graphics rendering system that generates the ever changing images at 20 to 30 frames per second.
3. A tracking system that continuously informs the position and orientation of the user’s movements.
4. The database construction and maintenance system to build and maintain a detailed and realistic model of the virtual world.
5. A sound system that can produce high quality directional sounds and simulated sound fields.
6. Devices like tracked gloves with pushbuttons to enable users to specify their interactions with the virtual objects.

Span of Virtual Reality:

Virtual Reality can lead to a new exciting world of innovations and entertainment. Entertainment industry is Billion Dollar market where new technologies play major role to create a huge user base. Virtual Reality is getting popular nowadays for such an immersed experience in Gaming, Entertainment and training areas. Whether it’s an expensive, dangerous or impractical to do something in reality, VR makes it real for you.

VR is increasingly playing major significance in following areas:

• Architecture
• Construction
• Sports
• Medical
• Gaming
• Entertainment
• Cinema

Military training to Medical surgery training can be experienced more deeply than real. It will not be surprising if we say

Virtual Reality or Immersed System can change digital interface systems we see today.

IP Spoofing

IP SPOOFING:

“IP address spoofing” is a technique that involves replacing the IP address of an IP packet’s sender with another machine’s IP address.

IP spoofing refers to connection hijacking through a fake Internet Protocol (IP) address. IP spoofing is the action of masking a computer IP address,so that it looks like it is authentic.

• IP Spoofing is a technique used to gain unauthorized access to computers.
  • `IP: Internet Protocol
  • `Spoofing: using somebody else’s information
• Exploits the trust relationships.

Types of IP Address:

1. IP is connectionless, unreliable
2. TCP connection-oriented

A Blind Attack:

Host I can not see what Host V send back

 IP SPOOFING STEPS:

1. Selecting a target host (the victim)
2. Identify a host that the target “trust”
3. Disable the trusted host, sampled the target’s TCP sequence
4. The trusted host is impersonated and the ISN forged.
5. Connection attempt to a service that only requires address-based authentication.
6. If successfully connected, executes a simple command to leave a back-door.

IP Spoofing Attacks:

• Man in the middle-Packet sniffs on link between the two end points, and therefore can pretend to be one end of the connection.
• Routing-redirects routing information from the original host to the attacker’s host.
• Flooding / Smurfing-The attacker redirects individual packets by the hacker’s host.

Attacks:

Flooding: SYN flood fills up the receive queue from random source addresses.

Smurfing:  ICMP packet spoofed to originate from the victim, destined for the broadcast address, causing all hosts on the network to respond to the victim at once.

IP-Spoofing Facts:

• IP protocol is inherently weak
• Makes no assumption about sender/recipient
• Nodes on path do not check sender’s identity
• There is no way to completely eliminate IP spoofing
• Can only reduce the possibility of attack

Disable Ping Command:

• ping command has rare use
• Can be used to trigger a DOS attack by flooding the victim with ICMP packets
• This attack does not crash victim, but consume network bandwidth and system resources
• Victim fails to provide other services, and halts if runs out of memory

FIREWALL:

• Limit traffic to services that are offered
• Control access from within the network
• Free software: ipchains, iptables
• Commercial firewall software
• Packet filters: router with firewall built-in
• Multiple layer of firewall

Google Glass

What is Google Glass?

• Google Glass is a wearable, voice-controlled Android device that resembles a pair of eyeglasses and displays information directly in the user’s field of vision.
• Google’s project program for developing a line of hands-free,intelligent devices that can be worn by users as “wearable computing” eyewear. The first product release from Project Glass, Google Glass, was available for beta testers (U.S. residents only) to purchase in 2013, for $1,500 plus tax.
• Google Glass is a headset, or optical head-mounted display, that is worn like a pair of eyeglasses. It was developed with the mission of producing a ubiquitous computer.

Google Glass Features:

1. Record Videos, Take Pictures:

Just say the word and Google Glass will take a picture or record a video ` you will never have to touch the hardware.

2. Show Messages:

Google Glass will show you text messages as well as emails you receive and allow you to reply to them via voice commands.

3. Find Information:

If you are in the habit of Googling things a lot, you will find that your task has been made easier by the new Glass. You simply need to ask a question and the device will pull the answer from the internet.

4. Show Maps:

The widely used Google Maps are integrated into Glass, so that users will be able to chart the course of their journey or look up locations or establishments via voice commands.

5. Live Video Sharing:

Google Glass can show the world what you are seeing ` live! If you are attending a family function, your child’s school play or a concert, you can share the feed with your friends and family in real-time and make them a part of the experience.

6. Integrates Google Now:

Google Now, the digital voice assistant from the search giant, has been integrated in this device. It will keep track of your daily habits, such as when you leave for office or the route you take.

7. Translate:

This is a neat feature that may come in handy when you travel abroad. You simply need to ask Google Glass to translate a phrase or sentence from one language to another and it will speak that out.

 

Applications of Google Glass:

Google Glass applications are free applications built by third-party developers. Glass also uses many existing Google applications, such as Google Now, Google Maps, Google+, and Gmail.

Third-party applications announced at South by Southwest (SXSW) include Evernote, Skitch, The New York Times, and Path.

Cell Phone Jammer

What is Jammer?

• Cell phone jammers are devices that create a temporary “dead zone” to all cell phone traffic in their air system.
• A cell phone jammer is an instrument used to prevent cellular phones and their mobile signals to a base station. When used, the jammer effectively disables cellular phones in the area.
• Other types of jammers -radar jammer  and radio jammer.

Size of Jammer:

Some cell-phone jammers are made to look like actual phones. Others are briefcase-sized or larger. The biggest jammers used by police and the military can be mounted in vehicles for convoy security.

Why Jammers are used?

• Cell phone jamming devices were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists.
• Examples include: security zones public transport,classrooms,temples,jails,govt.buildings,military bases, industries etc.

How Jammer Works:

A jamming device transmits – same radio frequencies as the cell phone, the communication between the phone and the cell-phone base station in the tower. It’s a called a denial-of-service attack.

• Jammers block cell phone use by sending out radio waves along the same frequencies that cellular phones use at a  high enough power that the two signals collide and cancel each other out.
• This causes  interference with communication of cell phones and towers to render the phones  unusable.On most  phones, the network would be out of range.

What is Inside the jammer?

Antenna: 

Every jamming – antenna to send the signal. Some are contained within an electrical cabinet. On stronger devices, antennas are external to provide longer range and may be tuned for individual frequencies.

Power supply
Smaller jamming – battery operated.

Some look like cell phone and use cell-phone batteries. Stronger devices – plugged into a standard outlet or wired into a vehicle’s electrical system.

Circuitry
The main electronic components of a jammer are:

                Voltage-controlled oscillator – Generates the radio signal – interfere with the cell phone signal.

                Tuning circuit – Controls the frequency at which the jammer broadcasts its signal by sending a particular voltage to the oscillator.

                Noise generator – Produces random electronic output in a specified frequency range to jam the cell-phone network signal.

RF amplification (gain stage) – Boosts the power of the radio frequency output to high enough levels to jam a signal.

Applications of jammer?

1. Cell phone jamming devices were originally developed for law enforcement and the military to interrupt communications by criminals and terrorists
2. It has been widely reported that a cell-phone jammer thwarted an assassination attempt on Pakistani President Musharraf in December 2003.
3. Used in areas where radio transmissions are dangerous, such as areas with a potentially explosive atmosphere, such as chemical storage facilities or grain elevators.

Introduction of Tripwire

What is Tripwire ?

• —Reliable intrusion detection system.—
• —Tool that checks
  400 × 150 – gardnertackle.co.uk

  to see what changes have been made in your system.—

• —Pinpoints, notifies, determines the nature, and provides information on the changes on how to manage the change.—
• —Mainly monitors the key attributes(like binary signature, size and other related data) of your files.—
• —Changes are compared to the established good baseline.—
• —Security is compromised, if there is no control over the various operations taking place.

How does it works:

1. —First, a baseline database is created, storing the original attributes like binary values in registry.—
2. —If the host computer is intruded, the intruder changes these values to go undetected.—
3. —The TripWire software constantly checks the system logs to check if any unauthorized changes were made.—
4. —If so, then it reports to the user.
5. —User can then undo those changes to revert the system back to the original state.

Where it is used?

• —Tripwire for Servers(TS) is software used by servers.—
• — Can be installed on any server that needs to be monitored for any changes.—
• —Typical servers include mail servers, web servers, firewalls, transaction server, development server.—
• —It is also used for Host Based Intrusion Detection System(HIDS) and also for Network Intrusion Detection System(NIDS).—
• —It is used for network devices like routers, switches, firewall, etc.
• —If any of these devices are tampered with, it can lead to huge losses for the Organization that supports the network.

Tripwire for Network Devices:

• Tripwire for network devices maintains a log of all significant actions including adding and deleting nodes, rules, tasks and user accounts.
• Automatic notification of changes to your routers, switches and firewalls.
• Automatic restoration of critical network devices.
• Heterogeneous support for today’s most commonly used network devices.

Tripwire for servers:

• For the tripwire for server’s software to work two important things should be present `the policy file and the database.
• The Tripwire for server’s software conducts subsequent file checks automatically comparing the state of system with the baseline database.
• Any inconsistencies are reported to the Tripwire manger and to the host system log file.
• Reports can also be emailed to an administrator.

There are two types of  Tripwire Manager

• Active Tripwire Manager
• Passive Tripwire Manager

• This Active Tripwire Manager gives a user the ability to update the database, schedule integrity checks, update and distribute policy and configuration files and view integrity reports.
• The Passive mode only allows to view the status of the machines and integrity reports.

How to Install and Use:

• —Install Tripwire and customize the policy file.—
• —Initialize the Tripwire database.—
• —Run a Tripwire integrity check.—
• —Examine the Tripwire report file.—
• —Take appropriate security measures.—
• —Update the Tripwire database file.—
• —Update the Tripwire policy file.—

What is the benefits of Tripwires:

—Increase security:  Immediately detects and pinpoints unauthorized changes.

—Instill Accountability:  Tripwire identifies and reports the sources of changes.

—Gain Visibility:  Tripwire software provides a centralized view of changes across the enterprise infrastructure and supports multiple devices from multiple vendors.

—Ensure Availability:  Tripwire software reduces troubleshooting time, enabling rapid discovery and recovery. Enables the fastest possible restoration back to a desired, good state.

What are the features of tripwire?

—The main attractive feature of this system is that the

•  Software generates a report about which file has been violated, when the file has been violated and also what   information in the files have been changed.
• —If properly used it also helps to detect who made the changes.—
• —Proper implementation of the system must be done with a full time manager and crisis management department.
