 Sandbox (computer security) - Wikipedia, the free encyclopedia
The sandbox typically provides a tightly-controlled set of resources for guest programs to run in, such as scratch space on disk and memory.
Capability systems can be thought of as a fine-grained sandboxing mechanism, in which programs have the ability to do specific things based on what capabilities (usually represented as opaque tokens) they hold.
Sometimes a sandbox is set up to run programs that are still under development and have the potential to damage the system or which are otherwise difficult to restore to their original configuration.

 Sandbox Project, Due 04/04/2005
In computer security, a sandbox is a safe place for running semi-trusted programs or scripts, often originating from a third party.
The sandbox security model provides a tightly-controlled set of resources for foreign programs to run in, such as a small "scratch-space" on the disk and a section of memory to carry out instructions.
The sandbox may allow some user interaction, and the user may be prompted to allow or disallow certain actions as the program runs.

 SMO COMPUTER SECURITY 12/98   (Site not responding. Last check: 2007-11-02)
Java's security generally requires that the execution of the coding occur within a virtual "sandbox" of sorts to ensure that applets play by the rules.
Security managers know these decisions should not be left to the average user, who has neither the expertise nor the security acumen to make the right decision every time.
Security experts, such as Edward Felten, of Princeton University's Secure Internet Programming Laboratory, suggest that management ensure that employees are always using the most up-to-date versions of Web browsers and that they download and install the security patches offered by vendors of all Internet products used.

Aside from the discussion list, another list facilitates the secure distribution of emergency samples and members of the list are expected to send samples of any viruses the organizations they work for consider worthy of raising public warnings about.
CA uses this metric to measure a malware's potential to spread to other computers.  This metric is given the second highest weight, in combination with Wild and Destructiveness metric, to calculate the overall threat assessment.
While these can be used by security managers, wishing to shore up their security, the tools are as likely used by attackers to evaluate where to start an attack.

Computer security requires lots of plodding, methodical examination of details that will hopefully result in boring and predictable computers.
Likewise, connecting a computer to a network puts you at risk for theft or loss of data, but most people are loath to permanently disconnect their systems from the Internet.
Computer security professionals say users and administrators should develop a threat model, which states what you're trying to protect from whom.

 Sandbox, Virtualization, and Lockdown Technology - Wilders Security Forums
A virtual PC is like a sandbox - any configuration changes on it have absolutely no effect on the host system, but are based on the host system's hardware.
Essentially your applications have now moved from being trusted, with their actions only confined to the disk usage restrictions of the current user account, to untrusted apart from a small subset of all their possible function calls which are allowable.
Computer systems and applications are 'imaged' and excuted in the virtual volume.

Our approach to security is deeply rooted in the concepts of operating systems and is based on access control in a wider sense.
An IT security policy is a document intended for the human reader which defines the attitude of an institution or organization towards IT security and specifies procedures, guidelines and rules in different detail.
Our interest focuses on sandbox models that support qualitative and quantitative access control not only between the runtime environment and the OS but also within the runtime environment to safeguard concurrently running applications or applets against each other.

 Java Security Architecture: -
The original security model provided by the Java platform is known as the sandbox model, which existed in order to provide a very restricted environment in which to run untrusted code obtained from the open network.
The essence of the sandbox model is that local code is trusted to have full access to vital system resources (such as the file system) while downloaded remote code (an applet) is not trusted and can access only the limited resources provided inside the sandbox.
The sandbox model was deployed through the Java Development Kit (JDK), and was generally adopted by applications built with JDK 1.0, including Java-enabled web browsers.

 Demystifying Java security
The first is the very meaning of the term "secure." The definition of a "secure system" is as elusive as that of "beauty" or "art." (The authors of Securing Java state that the only secure computer system is one that is turned off and buried under concrete!)
Lines such as "claims about Java's security have been greatly exaggerated" and "Although denial of service attacks are a real concern, Java's designers were not able to protect users from this class of attacks" demonstrate how refreshingly objective these authors are.
The authors have constructed one of the most important books on Java security, having achieved their stated goal of "separat[ing] fact from fiction when it comes to mobile code security." While the book belongs on the bookshelf of everyone who is serious about Java, it does have a few limitations.

 Introduction
The focus of research of the CNS group at Texas AandM University is directed toward developing approaches to increase the security of existing systems without severely impacting their usability and to increase the confidence in both existing and new systems in a cost-effective and user-friendly manner.
Obviously, computer and network security necessarily includes issues in computer and network system specifications, verification, testing, validation, and reliability, as well as topics from system design, architecture, information and database security, risk analysis and prediction, encryption, fault tolerance and damage assessment.
The Network Security "Sandbox" is a fully contained facility where different network and system security environments and tools may be taught and attack/defend labs conducted without effecting outside systems.

 Java Security Evolution and Concepts, Applet Security
To utilize a variety of security enhancements in the platform and the Java plug-in, we will try to upgrade the applet that we studied in the 1.2 environment to the 1.3 environment using the plug-in.
The applet generated a security exception since there was nothing specified in the policy file to permit that operation.
Under these schemes, it is no longer left to the developer to assemble the building blocks to provide security; instead, the developer and the deployer share responsibility in providing overall system security with lesser emphasis on programming and more emphasis on customization via a declarative model.
