What is difference between capabilities list and access list?
1. Access Control ListsAn ACL system has at least five namespaces whose relationships need to be considered:The namespace of file names: /tmp/fooThe namespace of unique object identifiers: (dev 22, inode 36, type file)The namespace of user identities (uid 52476)For each object type (file, disk, terminal, ...), the namespace of operations that object can perform.The namespace of process identifiers (process 719)In an access list system, it is assumed that there are two global mappings:principal: process identity -> user identityfs_lookup: file name -> object identity That is, every process has an assigned user identity and every file name can be translated into a unique object identifier. Hanging off of every unique object is a further mapping:acl: (object identity, user identity) -> operation(s) Given a process proc that wishes to perform an operation op on an object object, the protection mechanism in an access list system is to test the following predicate:op in acl(object, principal(p)) In the special case of the "open" call, this test is modified to be:op in acl(fs_lookup(filename), principal(p)) 2. Capability SystemsA capability system has at least four namespaces whose relationships need to be considered:The namespace of unique object identifiers: (dev 22, inode 36, type file)For each object type (file, disk, terminal, ...), the namespace of operations that object can perform.The namespace of process identifiers (process 719)The namespace of capabilities (object 10, operation set S)In a capability system, it is assumed that there is one local mapping for each processcap: (process identity, index) -> capability That is, every process has a list of capabilities. Each capability names an object and also names a set of legal operations on that object.There are also two "accessor" functions:obj: capability -> object identityops: capability -> operations Given a process proc that wishes to perform an operation op on an object object, the process must first possess a capability naming that object. That is, it must possess a capability at some index i such thatobject == obj(caps(p,i)) To perform an operation, the process names the "index" iof that capability to be invoked from the per-process list. The protection mechanism in a capability system is to test the following predicate:op in ops(caps(p,i)) Capability systems typically do not have a distinguished "open" call.3. Some Differences This section is incomplete.Simply comparing the predicates shows that there is a significant difference between the two systems:ACL: op in acl(object, principal(p)) Capability: op in ops(caps(p,i)) An obvious difference is that the capability model makes no reference to any notion of "principal".Another obvious difference is that the capability model has a parameter "i". This allows the process to specify whichauthority it wants to exercise, which is why only the capability model can solve the confused deputy problem.

To what extent can your neighbor spy on you using shortwave radio?
It's entirely up to you. If you're transmitting, anybody in the world has free open access to everything you put "over the air". If you're not transmitting, nobody can see or hear anything you say or do in your home.
When implementing secure network administration principles what is configured to restrict a subnet from transmitting FTP traffic to a particular server across the network?
Access control list
Which network design process identifies where to place access points?
A site survey is the network design process that identifies where to place access points.
How does cable modem internet access relate to bandwidth?
To access the internet via broadband cable, you will need a cable modem. Bandwidth is used for transmitting the signals of the internet to and from your home, and the cable modem is in place to allow the signals to be sent and received.
Should radio waves be controlled by the government?
Radio waves are controlled by the people who operate transmitting devices and by the laws of nature, not by the government. The government controls access to the privilege of operating transmitting devices. If that access were not controlled, the entire radio spectrum would sound like the 27 MHz 'citizen's band', and nobody would get any productive use out of it. Including would-be police, fire, ambulance, and cellphone users.
What is token based media access?
Token-based media access is a controlled media access method in which computers pass a special sequence of bits between them; only the node holding this token can transmit on the network. After transmitting its data, or if it has no data to transmit, a node passes the token to the next computer on the network. Neeraj
