In computer science, protection mechanisms are built into a computer architecture to support the enforcement of security policies. A simple definition of a security policy is “to set who may use what information in a computer system”.
What is a capability based system?
Capability-based security. A capability (known in some systems as a key) is a communicable, unforgeable token of authority. It refers to a value that references an object along with an associated set of access rights. A user program on a capability-based operating system must use a capability to access an object.

What is the access control list?
An access control list (ACL), with respect to a computer file system, is a list of permissions attached to an object. An ACL specifies which users or system processes are granted access to objects, as well as what operations are allowed on given objects. Each entry in a typical ACL specifies a subject and an operation.
What is content dependent access control?
1 INTRODUCTION ‘Content-dependent’ access control is a form of access control required by many applications. It is defined as access control where the decision to allow access to an object depends upon the value of attributes of the user and target objects themselves.
What is the purpose of an access control list?
An ACL or Access control list is a common means by which access to and denial of services is controlled. On network devices such as Routers and firewalls, they act as filters for network traffic, packet storms, services and host access. Most of these devices come with standard or default ACL and allow for custom ACL’s.
Why is ACL used?
There are a variety of reasons we use ACLs. The primary reason is to provide a basic level of security for the network. ACLs are also used to restrict updates for routing from network peers and can be instrumental in defining flow control for network traffic.
What is a firewall ACL?
An access control list is an implementation of a type of logic that can selectively permit or deny certain packets to go through an interface. A firewall is a device which examines traffic passing through a part of the network and makes decisions about what to let through and what to block.
What is an ACL security?
An access control list (ACL) is a list of access control entries (ACE). Each ACE in an ACL identifies a trustee and specifies the access rights allowed, denied, or audited for that trustee. The security descriptor for a securable object can contain two types of ACLs: a DACL and a SACL.
What is an ACL on a router used for?
Cisco provides basic traffic filtering capabilities with access control lists (also referred to as access lists). Access lists can be configured for all routed network protocols (IP, AppleTalk, and so on) to filter the packets of those protocols as the packets pass through a router.

Rehabilitation and return to normal function after surgical repair of an ACL tear can take six to nine months. There needs to be a balance between trying to do too much work in physical therapy returning strength and range of motion and doing too little.
