2019 solar Belt power rankings: How execute you rank anybody but App status No. 1? | existent Questions and Pass4sure dumps

at the immediate of each conference previews run-via, I hold a gawk at how I understand the convention’s steadiness of vigor heading into the season. here's in no route in keeping with schedules, so they are not predictions. here's just how i'd rank the groups after writing heaps of phrases about each and every of them. they now Have already accomplished the MAC and convention usa.

here’s a link to every crew’s statistics, and each team’s identify beneath is linked to its preview.

Tier 1

1. Appalachian State

The goal of this vigour ranking exercise is for me to boost my own opinions as an alternative of with ease citing S&P+ projections. those projections are decent and are going to live extra rectify than my opinions a Great percent of the time, but this route i walkover on the checklist with each.

sometimes i will’t ignore what the numbers are telling me, even though. With App status dealing with a training exchange, there's numerous rationale to regard the Mountaineers could drop back to the solar Belt pack a petite bit in 2019. however they’re projected thirty first in S&P+ ... and the subsequent choicest crew in the conference is projected 69th. Plus, that No. 69 group (Troy) is additionally dealing with a head teaching change. S&P+’s next crew (No. 70 Arkansas State) returns its head coach but simply misplaced most of its assistants.

primarily based in basic terms on that hole, I’m giving the Mountaineers their personal tier. query marks? a Great deal. but they birth out forward of the pack.

Tier 2

2. Troy3. Georgia Southern4. Arkansas State5. UL-Lafayette

As a simple “get an additional video game on television in an exquisite decent ESPN slot” gambit, I don’t intellect the solar Belt instituting a convention title game despite having simply 10 teams. It’s semi-pointless from a contest standpoint — with five-crew divisions, you already play everybody to your division and nearly every person from the other — however some thing. accept your money.

am i able to lobby for a rearranging of divisions, although? I know Troy is a few hours east of mobile, but for competitors functions, can they flip Troy and South Alabama?

as a result of as things stand, it’s feasible that the three top of the line groups within the convention are in the solar Belt East. ultimate yr, per S&P+, it became three of the perquisite four, and because of an upset, the inaugural title game was No. 1 vs. No. 5. That’s not a very advantageous expose off.

Tier 3

6. ULM

I simply don’t know what to execute with ULM. It wouldn’t shock me in any respect if any of the Tier 2 groups gained the convention, but ULM successful it would shock me. however I additionally like the Warhawks quite a petite more than any of the teams below them. So I wager they accept a tier to themselves.

Tier 4

7. Texas State8. Coastal Carolina9. Georgia State10. South Alabama

One of these 4 teams will develop an excellent Hurry at bowl eligibility. ultimate year, Coastal came up just short. This 12 months, Texas status brings back one of the most greater skilled two-deeps in the nation, and if new coach Jake Spavital can design out how to ranking some facets while holding ultimate yr’s defensive prowess, the Bobcats may Have the most effectual shot.

right here’s how my statistical system has the solar Belt laid out for 2019, with zero equating to a yardstick FBS team. (you can ascertain replete 2019 S&P+ projections perquisite here.)

Scott Satterfield leaves behind an experienced, pleasant two-deep. And once more, the crew closest to App status has the identical coaching change considerations and less adventure.

both teams projected to improve the most, incidentally: Texas status and Georgia State. both return most of ultimate 12 months’s construction.

Projected conference wins, with yardstick wins in parentheses.

West Division
  • Arkansas status 5.7 (7.9)
  • ULM 3.eight (5.1)
  • UL 3.7 (5.8)
  • Texas status three.7 (5.3)
  • South Alabama 1.4 (2.6)
  • the first two conferences I previewed (the MAC and convention united states of america) may Have the tightest title races in FBS. The solar Belt likely won’t. Arkansas status has an almost two-game cushion in the West ...

    East Division
  • Appalachian status 6.9 (9.3)
  • Troy 5.four (7.9)
  • Georgia Southern four.9 (6.9)
  • Georgia status 2.4 (three.5)
  • Coastal Carolina 2.2 (four.4)
  • ... and only one team is within two games of App within the East.

    coaching changes, surprising attrition, upsets, etc., may develop both division race unique. Plus, in these conferences, the race to 6 wins is commonly as or extra exciting. but the favorites are obvious, and that’s as a minimum in portion on account of the unbalanced divisions. Troy vs. Arkansas status in the West? that might live a very advantageous race!

    No sin in fact stood out remaining yr as more efficient than the pack, however only just a few were capable of making tall performs.

    The spread on protection, although, became dramatic. You had some downright fabulous devices in App State, Troy, and Texas State, you had some successful bend-don’t-break attacks like Georgia Southern’s ... and you had three actually, really unhealthy defenses dragging down the averages.

    I’m going to exit on a limb with this one. Technically, they gained’t even comprehend that Barker is going to live Troy’s starter in 2019 — after his injury final 12 months, Sawyer Smith took over and confirmed bouts of competence, too. but Barker become genesis to hit a stage you hardly ever see.

    towards ULM, Coastal Carolina, and Georgia State, Barker completed forty four of 53 passes (83 percent!) for 552 yards, 5 touchdowns, no picks, and a ridiculous 201.6 passer rating.

    expecting a full-season 200-plus score is likely too an terrible lot, but his upside is the optimum in the convention, even greater than that of Evans or App State’s Zac Thomas.

    This selection was lots less difficult: pick essentially the most energetic participant from the most fulfilling protection. growth, finished.

    Java 2 Platform Security | existent questions and Pass4sure dumps

    This chapter explains the Java 2 platform architecture and its security features as they apply to edifice Java applications. In particular, it describes the various Java platforms and the core security features that contribute to the end-to-end security of Java-based applications running on various systems—from servers to stand-alone computers, computers to devices, and devices to smart cards.

    This chapter is from the engage 

    Topics in This Chapter

  • Java Security Architecture
  • Java Applet Security
  • Java Web Start Security
  • Java Security Management Tools
  • J2ME Security Architecture
  • Java Card Security Architecture
  • Securing the Java Code
  • Sun's Java philosophy of "Write Once, Hurry Anywhere" has been an evolving success narrative since its inception, and it has revolutionized the computing industry by delivering to us the most capable platform for edifice and running a wide compass of applications and services. In general, the Java platform provides a general-purpose object-oriented programming language and a yardstick runtime environment for developing and delivering secure, cross-platform application solutions that can live accessed and dynamically loaded over the network or Hurry locally.

    With the release of the Java 2 Platform, Sun categorized the Java technologies under three key major editions in order to simplify software evolution and deployment. The Java 2 yardstick Edition (J2SE) provides the runtime environment and API technologies for developing and executing basic Java applications, and it also serves as the secure foundation for running Java enterprise applications. The Java 2 Enterprise Edition (J2EE), or the J2EE Platform, is a set of standards and API technologies for developing and deploying multi-tier industry applications. To advocate Java on microdevices and embedded systems, Java 2 Micro Edition (J2ME) provides the runtime environment and API technologies for addressing the needs of consumer electronics and devices. With its widespread adoption, today Java technology is enabled and executed from smart cards to microdevices, handhelds to desktops, workstations to enterprise servers, mainframes to supercomputers, and so on.

    To facilitate end-to-end security of the Java platform-based application solutions, the Java runtime environment (JRE) and the Java language provide a solid security foundation from the ground up by imposing tenacious format and structural constraints on the code and its execution environment. This distinguishes the Java platform from other application programming languages—it has a well-defined security architectural model for programming Java-based solutions and their secure execution.

    In this chapter, they will explore the various Java platforms and the intricate details of their security architecture that contribute to the end-to-end security of Java-based application solutions. In particular, they will study Java security and the inherent features of the following technologies:

  • J2SE security
  • Java applet security
  • Java Web start security
  • Java security management tools
  • J2ME security
  • Java Card security
  • Java Code obfuscation
  • Security has been an integral portion of Java technology from day one. Security is also an evolving design goal of the Java community—building and running secure and robust Java-based network applications. The primary intuition for Java's success today as a secure execution environment is the intrinsic security of its architectural foundation—the Java Virtual Machine (JVM) and the Java language. This foundation achieves the basic Java security goal and its definitive ways for extending security capabilities to ensure features such as confidentiality, integrity, trust, and so forth. A second intuition for its success is its faculty to deliver an interoperable and platform-neutral security infrastructure that can live integrated with the security of the underlying operating system and services.

    The Java Virtual Machine (JVM)

    The JVM is an abstract computing engine that resides on a host computer. It is the execution environment for the Java programming language and has the primary responsibility for executing the compiled code by interpreting it in a machine-independent and cross-platform fashion. The JVM is often referred to as the Java runtime environment. While executing a Java program running on top of the JVM, the JVM insulates the application from the underlying differences of the operating systems, networks, and system hardware, thus ensuring cross-platform compatibility among entire of the implementations of the Java platform.

    The Java language allows creation of general-purpose programs called Java classes that limn a Java program or an application. The Java classes compile into a format called Java's executable bytecodes, which are quite similar to the machine language that can Hurry on top of a JVM. The JVM also allows users to download and execute untrusted programs and applications from remote resources or over a network. To advocate delivery of Java components over the network, the JVM controls the primary security layer by protecting users and the environment from malicious programs. To enable security, the JVM enforces stringent measures ensuring systems security on the host client machine and its target server environments.

    Distributing the executable Java bytecode over a network or running automatically inside a Web browser or a client's machine leads to different security risks and attacks, such as disclosure of the target environment to the untrusted applications and damage or modification of the client's private information and data. For example, Java applets downloaded from a network are not allowed to Have access to, read from, or write to a local file system. They are also not allowed to create network connections to any host system except the one where they are deployed. On the other hand, stand-alone Java applications that reside and Hurry locally as trusted applications are not subjected to these security features. The key issue is that allowing untrusted applications such as Java applets to live downloaded from a network via a Web browser and letting them access sure resources on the host computer paves the route for security breaches and becomes a potential avenue for the spread of viruses. To obviate known security breaches and threats, the JVM provides a built-in Java security architecture model, configurable security policies, access control mechanisms, and security extensions. Because of the built-in JVM safety features, Java programs can Hurry safely and are more securely protected from known vulnerabilities.

    The Java Language

    Java is a general-purpose object-oriented programming language similar to C++. It delivers platform-neutral compiled code that can live executed using a JVM and is intended for disburse in distributed application environments, heterogeneous systems, and diverse network environments. The Java language is also designed to provide for the security and integrity of the application and its underlying systems at entire levels—from the Java language constructs to the JVM runtime and from the class library to the complete application.

    The several inherent features of the Java language that provide for the secure Java platform are as follows:

  • The language defines entire primitives with a specific size and entire operations are defined to live in a specific order of execution. Thus, the code executed in different JVMs will not disagree from the specified order of execution.
  • The language provides access-control functionality on variables and methods in the kick by defining designation space management for character and procedure names. This secures the program by restricting access to its critical objects from untrusted code. For example, access is restricted by qualifying the character members as public, protected, private, package, etc.
  • The Java language does not allow defining or dereferencing pointers, which means that programmers cannot forge a pointer to the recollection or create code defining offset points to memory. entire references to methods and instance variables in the class file are done via symbolic names. The elimination of pointers helps to obviate malicious programs like computer viruses and misuse of pointers such as accessing private methods directly by using a pointer starting from the object's pointer, or running off the immediate of an array.
  • The Java kick encapsulation supports "programming by contract," which allows the reuse of code that has already been tested.
  • The Java language is a strongly typed language. During compile time, the Java compiler does extensive character checking for character mismatches. This mechanism guarantees that the runtime data character variables are compatible and consistent with the compile time information.
  • The language allows declaring classes or methods as final. Any classes or methods that are declared as final cannot live overridden. This helps to protect the code from malicious attacks such as creating a subclass and substituting it for the original class and override methods.
  • The Java Garbage Collection mechanism contributes to secure Java programs by providing a transparent storage allocation and recovering unused recollection instead of deallocating the recollection using manual intervention. This ensures program integrity during execution and prevents programmatic access to fortuitous and incorrect freeing of recollection resulting in a JVM crash.
  • With these features, Java fulfills the promise of providing a secure programming language that gives the programmer the freedom to write and execute code locally or ration it over a network.

    Java Built-in Security Model

    In the previous two sections, they briefly looked at the basic security features provided by the JVM and the Java language. As portion of its security architecture, Java has a built-in policy-driven, domain-based security model. This allows implementing security policies, protecting/controlling access to resources, rule-based class loading, signing code and assigning levels of capability, and maintaining content privacy.

    In the first release of the Sun Java Platform, the Java evolution Kit 1.0.x (JDK) introduced the notion of a sandbox-based security model. This primarily supports downloading and running Java applets securely and avoids any potential risks to the user's resources. With the JDK 1.0 sandbox security model, entire Java applications (excluding Java applets) executed locally can Have replete access to the resources available to the JVM. Application code downloaded from remote resources, such as Java applets, will Have access only to the restricted resources provided within its sandbox. This sandbox security protects the Java applet user from potential risks because the downloaded applet cannot access or alter the user's resources beyond the sandbox.

    The release of JDK 1.1.x introduced the notion of signed applets, which allowed downloading and executing applets as trusted code after verifying the applet signer's information. To facilitate signed applets, JDK 1.1.x added advocate for cryptographic algorithms that provide digital signature capabilities. With this support, a Java applet class could live signed with digital signatures in the Java archive format (JAR file). The JDK runtime will disburse the trusted public keys to verify the signers of the downloaded applet and then deal it as a trusted local application, granting access to its resources. design 3-1 shows the representation of a sandbox in the JDK 1.1 security model.

    Java 2 Security Model

    The release of J2SE [J2SE] introduced a number of significant enhancements to JDK 1.1 and added such features as security extensions providing cryptographic services, digital certificate management, PKI management, and related tools. Some of the major changes in the Java 2 security architecture are as follows:

  • Policy-driven restricted access control to JVM resources.
  • Rules-based class loading and verification of byte code.
  • System for signing code and assigning levels of capability.
  • Policy-driven access to Java applets downloaded by a Web browser.
  • In the Java 2 security architecture, entire code—regardless of whether it is Hurry locally or downloaded remotely—can live subjected to a security policy configured by a JVM user or administrator. entire code is configured to disburse a particular domain (equivalent to a sandbox) and a security policy that dictates whether the code can live Hurry on a particular domain or not. design 3-2 illustrates the J2SE security architecture and its basic elements.


    Figure 3-2 Java 2 Security architecture and basic elements

    Let's hold a more detailed gawk at those core elements of the Java 2 security architecture.

    Protection Domains ( ): In J2SE, entire local Java applications Hurry unrestricted as trusted applications by default, but they can also live configured with access-control policies similar to what is defined in applets and remote applications. This is done by configuring a ProtectionDomain, which allows grouping of classes and instances and then associating them with a set of permissions between the resources. Protection domains are generally categorized as two domains: "system domain" and "application domain." entire protected external resources, such as the file systems, networks, and so forth, are accessible only via system domains. The resources that are portion of the lone execution thread are considered an application domain. So in reality, an application that requires access to an external resource may Have an application domain as well as a system domain. While executing code, the Java runtime maintains a mapping from code to protection domain and then to its permissions.

    Protection domains are determined by the current security policy defined for a Java runtime environment. The domains are characterized using a set of permissions associated with a code source and location. The class encapsulates the characteristics of a protected domain, which encloses a set of classes and its granted set of permissions when being executed on behalf of a user.

    Permissions ( ): In essence, permissions determine whether access to a resource of the JVM is granted or denied. To live more precise, they give specified resources or classes running in that instance of the JVM the faculty to permit or contradict sure runtime operations. An applet or an application using a security manager can obtain access to a system resource only if it has permission. The Java Security API defines a hierarchy for leave classes that can live used to configure a security policy. At the root, is the abstract class, which represents access to a target resource; it can also comprise a set of operations to construct access on a particular resource. The leave class contains several subclasses that limn access to different types of resources. The subclasses belong to their own packages that limn the APIs for the particular resource. Some of the commonly used leave classes are as follows:

    For wildcard permissions

    For named permissions

    For file system

    For network

    For properties


    For runtime resources


    For authentication

    For graphical resources


    Example 3-1 shows how to protect access to an kick using permissions. The code shows the caller application with the required leave to access an object.

    Example 3-1. Using Java permissions to protect access to an object // Create the kick that requires protection String protectedObj = "For trusted eyes only"; // create the required leave that will // protect the object. // Guard, represents an kick that is used to protect // access to another object. Guard myGuard = new PropertyPermission ("java.home", "read"); // Create the guard GuardedObject gobj = new GuardedObject(protectedObj, myGuard); // accept the guarded object try { kick o = gobj.getObject(); } tangle (AccessControlException e) { // Cannot access the object }

    Permissions can also live defined using security policy configuration files (java.policy). For example, to accord access to read a file in "c:\temp\" (on Windows), the FilePermission can live defined in a security policy file (see illustration 3-2).

    Example 3-2. Setting Java permissions in policy configuration file grant{ leave "c:\\temp\\testFile", "read"; };

    Policy: The Java 2 security policy defines the protection domains for entire running Java code with access privileges and a set of permissions such as read and write access or making a connection to a host. The policy for a Java application is represented by a Policy object, which provides a route to declare permissions for granting access to its required resources. In general, entire JVMs Have security mechanisms built in that allow you to define permissions through a Java security policy file. A JVM makes disburse of a policy-driven access-control mechanism by dynamically mapping a static set of permissions defined in one or more policy configuration files. These entries are often referred to as accord entries. A user or an administrator externally configures the policy file for a J2SE runtime environment using an ASCII text file or a serialized binary file representing a Policy class. In a J2SE environment, the default system-wide security policy file java.policy is located at <JRE_HOME>/lib/security/ directory. The policy file location is defined in the security properties file with a setting, which is located at <JRE_HOME>/lib/security/

    Example 3-3 is a policy configuration file that specifies the leave for a signed JAR file loaded from "*" and signed by "javaguy," and then grants read/write access to entire files in /export/home/test.

    Example 3-3. Setting codebase and permissions in policy configuration file accord signedBy "javaguy", codebase "*" { leave "/export/home/test/*", "read,write"; };

    The J2SE environment also provides a GUI-based utensil called "policytool" for editing a security policy file, which is located at "<JAVA_HOME>/bin/policytool."

    By default, the Java runtime uses the policy files located in:

    ${java.home}/jre/lib/security/java.policy ${user.home}/.java.policy

    These policy files are specified in the default security file:


    The effectual policy of the JVM runtime environment will live the union of entire permissions in entire policy files. To specify an additional policy file, you can set the system property at the command line:

    java MyClass

    To ignore the policies in the file and only disburse the custom policy, disburse '==' instead of '=':

    java MyClass

    SecurityManager ( java.lang.SecurityManager ): Each Java application can Have its own security manager that acts as its primary security guard against malicious attacks. The security manager enforces the required security policy of an application by performing runtime checks and authorizing access, thereby protecting resources from malicious operations. Under the hood, it uses the Java security policy file to settle which set of permissions are granted to the classes. However, when untrusted classes and third-party applications disburse the JVM, the Java security manager applies the security policy associated with the JVM to identify malicious operations. In many cases, where the threat model does not comprise malicious code being Hurry in the JVM, the Java security manager is unnecessary. In cases where the SecurityManager detects a security policy violation, the JVM will sling an AccessControlException or a SecurityException.

    In a Java application, the security manager is set by the setSecurityManager manner in class System. And the current security manager is obtained via the getSecurityManager manner (see illustration 3-4).

    Example 3-4. Using SecurityManager SecurityManager mySecurityMgr = System.getSecurityManager(); if (mySecurityMgr != null) { mySecurityMgr.checkWrite(name); }

    The class java.lang.SecurityManager consists of a number of checkXXXX methods like checkRead (String file) to determine access privileges to a file. The check methods summon the SecurityManager.checkPermission manner to find whether the calling application has permissions to perform the requested operation, based on the security policy file. If not, it throws a SecurityException.

    If you wish to Have your applications disburse a SecurityManager and security policy, start up the JVM with the option and you can also specify a security policy file using the policies in the option as JVM arguments. If you enable the Java Security Manager in your application but execute not specify a security policy file, then the Java Security Manager uses the default security policies defined in the java.policy file in the $JAVA_HOME/jre/lib/security directory. illustration 3-5 programmatically enables the security manager.

    Example 3-5. Using SecurityManager for restricting access control // Before the security manager is enabled, // this summon is possible System.setProperty("java.version","Malicious: Delete"); try { // Enable the security manager SecurityManager sm = new SecurityManager(); System.setSecurityManager(sm); } tangle (SecurityException se) { // SecurityManager already set } // After the security manager is enabled: // This summon is no longer possible; // an AccessControlException is thrown System.setProperty ("java.version", "Malicious: Delete");

    The security manager can also live installed from the command-line interface:

    java <ClassName>

    AccessController ( ): The access controller mechanism performs a dynamic inspection and decides whether the access to a particular resource can live allowed or denied. From a programmer's standpoint, the Java access controller encapsulates the location, code source, and permissions to perform the particular operation. In a typical process, when a program executes an operation, it calls through the security manager, which delegates the request to the access controller, and then finally it gets access or denial to the resources. In the class, the checkPermission manner is used to determine whether the access to the required resource is granted or denied. If a requested access is granted, the checkPermission manner returns true; otherwise, the manner throws an AccessControlException.

    For example, to check read and write leave for a directory in the file system, you would disburse the code shown in illustration 3-6.

    Example 3-6. Using AccessController try { AccessController.checkPermission (new FilePermission("/var/temp/*", "read,write")); } tangle (SecurityException e) { // Does not Have leave to access the directory }

    Codebase: A URL location of class or JAR files are specified using codebase. The URL may mention to a location of a directory in the local file system or on the Internet. illustration 3-7 retrieves entire the permissions granted to a particular class that's been loaded from a code base. The permissions are effectual only if the security manager is installed. The loaded class uses those permissions by executing Class.getProtectionDomain() and Policy.getPermissions().

    Example 3-7. Using codebase class URL codebase = null; try { // accept permissions for a URL codebase = new URL(""); } tangle (MalformedURLException e) { } tangle (IOException e) { } // Construct a code source with the code base CodeSource cs = new CodeSource(codebase, null); // accept entire granted permissions PermissionCollection pcoll = Policy.getPolicy().getPermissions(cs); // View each leave in the leave collection Enumeration enum = pcoll.elements(); for (; enum.hasMoreElements(); ) { leave p = (Permission)enum.nextElement(); System.out.println("Permission " + p); }

    To test illustration 3-7, illustration 3-8 is the policy file (test.policy), which provides leave to read entire system properties.

    Example 3-8. Policy file for testing permissions to a codebase accord codebase "" { // Give leave to read entire system properties leave java.util.PropertyPermission "*", "read"; };

    To ignore the default policies in the file, and only disburse the specified policy, disburse '==' instead of '='. With the policy just presented, you may Hurry the following:

    java TestClass

    CodeSource: The CodeSource allows representation of a URL from which a class was loaded and the certificate keys that were used to mark that class. It provides the selfsame notion as codebase, but it encapsulates the codebase (URL) of the code where it is loaded and also the certificate keys that were used to verify the signed code. The CodeSource class and its two arguments to specify the code location and its associated certificate keys are as follows:

    CodeSource(URL url, certs[]);

    To construct a code source with the code groundwork and without using certificates, you would disburse the following:

    CodeSource cs = new CodeSource(codebase, null);

    Bytecode verifier: The Java bytecode verifier is an integral portion of the JVM that plays the primary role of verifying the code prior to execution. It ensures that the code was produced consistent with specifications by a trustworthy compiler, confirms the format of the class file, and proves that the succession of Java byte codes are legal. With bytecode verification, the code is proved to live internally consistent following many of the rules and constraints defined by the Java language compiler. The bytecode verifier may also detect inconsistencies related to sure cases of array bound-checking and object-casting through runtime enforcement.

    To manually control the smooth of bytecode verification, the options to the Java command with the V1.2 JRE are as follows:

  • -Xverify:remote runs verification process on classes loaded over network (default)
  • -Xverify:all verifies entire classes loaded
  • -Xverify:none does no verification
  • ClassLoader: The ClassLoader plays a distinct role in Java security, because it is primarily liable for loading the Java classes into the JVM and then converting the raw data of a class into an internal data structure representing the class. From a security standpoint, class loaders can live used to establish security policies before executing untrusted code, to verify digital signatures, and so on. To implement security, the class loader coordinates with the security manager and access controller of the JVM to determine the security policies of a Java application. The class loader further enforces security by defining the namespace separation between classes that are loaded from different locations, including networks. This ensures that classes loaded from multiple hosts will not communicate within the selfsame JVM space, thus making it impossible for untrusted code to accept information from trusted code. The class loader finds out the Java application's access privileges using the security manager, which applies the required security policy based on the requesting context of the caller application.

    With the Java 2 platform, entire Java applications Have the capability of loading bootstrap classes, system classes, and application classes initially using an internal class loader (also referred to as primordial class loader). The primordial class loader uses a special class loader SecureClassLoader to protect the JVM from loading malicious classes. This class has a protected constructor that associates a loaded class to a protection domain. The SecureClassLoader also makes disburse of permissions set for the codebase. For instance, URLClassLoader is a subclass of the SecureClassLoader. URLClassLoader allows loading a class or location specified with a URL.

    Refer to illustration 3-9, which shows how a URLClassLoader can live used to load classes from a directory.

    Example 3-9. Using URLClassLoader // Create a File kick on the root of the // directory containing the class file File file = new File("c:\\myclasses\\"); try { // transfigure File to a URL URL url = file.toURL(); URL[] urls = new URL[]{url}; // Create a new class loader with the directory ClassLoader myclassloader = new URLClassLoader(urls); // Load in the class; // MyClass.class should live located in // the directory file:/c:/myclasses/com/security Class myclass = myclassloader.loadClass(""); } tangle (MalformedURLException e) { } tangle (ClassNotFoundException e) { }

    Keystore and Keytool: The Java 2 platform provides a password-protected database facility for storing trusted certificate entries and key entries. The keytool allows the users to create, manage, and administer their own public/private key pairs and associated certificates that are intended for disburse in authentication services and in representing digital signatures.

    We will hold a gawk in greater detail at the usage of the Java keystore and keytool and how these tools assist Java security in the section entitled "Java Security Management Tools," later in this chapter.

    Sun teams with mobile phone firms for Java apps | existent questions and Pass4sure dumps

    Java's creator and four mobile phone makers Have developed a process for testing and certifying Java 2 Micro Edition (J2ME) applications for wireless handheld devices.

    The Java Verified Process was spearheaded by Sun Microsystems, Motorola, Nokia, Siemens and Sony Ericsson in an endeavor to facilitate creation and dissemination of J2ME applications and to spur the adoption of standards for J2ME development.

    "This programme was set up to assist developers Have a lone means of testing their Java content and ensuring compatibility across devices from Motorola, Nokia, Siemens and Sony Ericsson," said Craig Miller, group marketing manager, consumer and mobile solutions group at Sun.

    There are about 250 million Java technology-enabled wireless devices from 31 manufacturers deployed in more than 75 carrier networks around the world, so this market presents a tremendous opening for J2ME developers, Miller said.

    There are also about 10,000 J2ME applications worldwide, he added.

    Once an application has been certified by the Java Verified Process it will receive the Java Powered Logo and each version of the application shipped will live signed digitally to guarantee the user it has not been tampered with.

    Adam Zawel, an analyst at the Yankee Group, said there now can live numerous versions of the selfsame J2ME application to accommodate the different ways suppliers Have implemented Java.

    "There needs to live a yardstick process though which application developers can certify their products and Have the faculty to write it once and publish it anywhere," he said, adding that this sort of simplification is necessary to accept more developers writing, distributing and profiting from J2ME applications.

    Zawel said the Java community could gawk to Qualcomm and what it has done with its Brew platform as a guide.

    Brew is a evolution platform for mobile devices for Code Division Multiple Access (CDMA) phones. Qualcomm has used its website to create a one-stop shop for Brew developers to accept their applications tested, certified and distributed to any Brew carriers.

    While the Java Verified Process provides a means for developers to accept their applications tested, it does not provide a yardstick means for distribution.

    However, Sun has announced it will aggregate a list of J2ME content from developers on its website and provide this list to operators.

    This route they can, potentially, deliver these applications over their own networks, which will capitalize the immediate user, because their operators will live able to offer them more products.

    Testing for the Java Verified process has been outsourced to four different companies that each Have offices around the world.

    These comprise Babel Media, Cap Gemini Ernst & Young, the National Software Testing Labs and RELQ Software.

    The cost to Have an application verified will compass between $200 and $400 depending on location.
