Security Models In JAVA

• Need For JAVA Security.
• The Sandbox Model or Java 1.0.
• Java 2 Platform Security Model.

11
Need For Security IN JAVA

• Code Mobility Can Be Useful.
• Improve Functionality of Services.
• Downloaded Executable Contents is Dangerous
• The Source May Be Unknown Hence
  Trusted.
• Downloaded Code May modify or destroy
  data in our System.
• They may be install other hostile
  code on our system.
• Hostile code may use the resources of
  our system.

12
Sandbox model

• The original security model provided by the Java
  platform.
• It existed in order to provide a very
  restricted environment in which to
• run untrusted code obtained from the open
  network. 

13
Java 2 Platform Security Model
14

• Fine Grained Access Control -
• Every code access to the resources
  based on what is defined in a policy file.
• Easily Configurable Security Policy -
• It is desirable to allow application
  builders and users to configure security
• policies without having to
  program.
• Easily Extensible Access Control Structure -
• The new architecture allows typed
  permissions and automatic handling of
• all permissions of the correct
  type.
• Extension of Security Checks to all Java programs
  -
• There is no longer a built-in concept
  that all local code is trusted.

15
How Sandboxing work ?

• Compile the Applet .
• Create JAR file for the Applet.
• Generate a pair of public/private keys.
• Sign the applet jar with private key.
• Export the certificate for public key.
• Import the certificate as a trusted certificate.
• Create the policy file.
• Load and run the Applet.

Performance of java
17
Twitter migrates core infrastructure to the JVM
and supports more than 400 million Tweets a day.
18
Java's innate scalability has played a key role
in enabling Netflix to expand its service to more
than 57 million members in 50 countries.
Collectively, these viewers enjoy more than 1
billion hours of shows and movies per month.
19
JAVA IN REAL WORLD

• 1.1 billion desktops run Java.
• 930 million Java Runtime Environment downloads
  each year.
• 3 billion mobile phones run Java.
• 10 times more Java phones ship every year than
  Apple and Android combined.
• 100 of all Blu-ray players run on Java.
• 1.4 billion Java Cards are manufactured each
  year.
• Java powers set-top boxes, printers, Web cams,
  games, car navigation systems, lottery terminals,
  medical devices, parking payment stations, and
  more.

Tiobe pypl

• TIOBE Index
• TIOBE ratings are
  calculated by counting hits of the most popular
• search engines.
• PYPL Index   
• The PYPLU Popularity of
  Programming Language Index is created
• by analyzing how often
  language tutorials are searched on Google.

• How many Java developers ?

Based on a survey made using various portals,
different sources for estimation popularity
contests, job market analysis and download
numbers of popular Java development
infrastructure products there are approximately
8,311,000 Java developers in the World.
