Internet Security and Privacy

NAB Internet Banking uses 128-bit SSL encryption technology. This is the current security standard utilized by most banks in connection with their internet banking customers.

It is an intermediate server that sits between your computer and the machine you try to connect to.

For example, a business could use a proxy server to connect to the internet. If so, individual computers in the office would not connect to internet directly, but connect to the proxy server which would forward the request to the internet, receive the response and hand it back to the computer that asked for it.

In such cases, the reasons to use a proxy include security, as the proxy server could filter out various attacks.

Proxy servers are also used to cache content. For example, your ISP may have a proxy server that caches the most popular pages so it can serve those pages more quickly. When used to serve content like this, it is called a caching proxy.

There are several other variants, what they all have in common is that the proxy acts as a middle man in the communication between two other computers.

These are two different things:

Stateful packet inspection is a firewalling technology where a record is kept of each session permitted through the firewall and then data is permitted back through if the sessions match up. (I am curently researching exactly *what* data is checked before a returned packet is permitted through.)

Network Address Translation (NAT) is more of a *routing* than firewalling technology (but I can't think of a network firewall that won't do this). This simply replaces either the source and/or destination IP network address with another IP address (NAT - it does what it says on the tin). The most common use of this is when a machine on a private IP address browses the internet: the router/firewall with a modem then replaces the source private IP with the public/internet IP address of the router. All other devices on the internet will know how to send traffic to and from the router without knowing anything about the setup of your private network/LAN. When the reply traffic arrives back at your router it knows which internal device sent traffic so can direct the traffic to the correct private IP address. This of course means (a) your private network is hidden and (b) the router does not know where to send traffic that hasn't originated from an internal device*... you could say it's firewalling.

*There are common exceptions to this: e.g. the router might do an opposite form of NAT where it knows that traffic to public IP 'a.b.c.d' goes to internal IP 192.168.x.y; I would say this is the second most common form of NAT.

Hope that helps.

It is perfectly acceptable to run both at the same time. I do at home, and have never had a problem myself.

There is no problem in using both, but Windows Firewall is superflous when you have got a Router with an integrated Firewall. They both do the same thing - block malicious INCOMING requests.

The problem is that any OUTGOING traffic is considered safe and that is a security issue you might want to address by installing a third party software firewall and disabling Windows Firewall (running two software firewalls on the same machine could cause conflicts).

Well the reason why I think the administrators blocked almost every game website is because in school they want you to focus and succeed not play games. That why there is something called the app-store for example not many people know this but sometimes websites tend to be unblocked some times but after you use it they block it again, and if you use it AGAIN they will block it for ever.

they really cannot be stoppped but you can try to prevent them from accessing your machine as best as you can eg windows firewall any virus program that has an additional firewall and spyware detectors and eliminators to keep their trojans and spying tools out your machine keep a close eye on the emails and attachments you open that's their way in along with web sites

this one works well just download the free version it doesnt make you upgrade in order to remove the viruses like most antivirus softwares http://free.avg.com/us-en/download?prd=afg#axzz0c3gQiJ2V

All of the Above

Depends on the site

Personally I would make an application with 2 sockets. you have one socket listening on port 125. you then set your browser settings to the IP address on which the proxy application is running. Then u make another socket which will read the HTTP headers... get the host... connect to them on port 80 and pass the information back to the browser through the first socket. so what ur doing essentially is getting the data from one socket storing it in a var and sending it off through the other socket. u'd have to store the data in bytes as opposed to a string because pictures and other mediawill contain byte information.

Data integrity is the protection of information from damage or deliberate manipulation.

In plain language, integrity insures that data hasn't been modified.

Integrity is obviously extremely critical for any kind of business or electronic commerce. Imagine if someone could modify invoices or financial records without detection.

• A electronic signature is an electronic form attached to a digital document to verify the signer's intent to sign. There are various electronic signature vendors in North America and across the world.
• A digital signature is an electronic signature with highly secure encryption which ensures document integrity and nonrepudiation.
• I use Signority (www.signority.com) secure electronic signature service. It is very easy and convenient. They also provide various authentication methods to ensure the highest level of security and confidentiality. Really love it!

No, But it may copy what you say so it's easier for others to find things

well my favorite place to hide stuff from my parents is a bit complicated.

u need tape and the item u want to hide.

take a dresser drawer out of your dresser and put tape across the item and stick it to the back of the drawer.

then reinsert the drawer into the dresser. that is the most hidden way i know.

yeah that would be a virus. they have command that will reset your computer after 50 or so executions. press controll alt delete and go to process and than go to start search and search everthing program that you dont know. Or you could get a anti virus program So here's what I would do, when faced with a randomly rebooting computer:

-Yes, I would consider upgrading to Windows XP, if the machine was capable of it.

-Make sure that anti-virus and anti-spyware utilities are running and up-to-date.

-Make sure that the operating system and all device drivers are as up-to-date as possible.

-Run a memory diagnostic such as Memtest86 or Windows memory Diagnostic.

-Run a hard disk diagnostic such as SpinRite.

It sounds like it has a piece of hardware installed in place of a standard modem card, which is pre-programmed with the site in question. You would have to open the computer, locate the relevant hardware, replace it with a standard modem card and install the new hardware. HOWEVER - since this is apparently a computer belonging to your employer, performing the modification would certainly void your contract of employment, and they could fire you on the spot when your 'modification' is discovered !

workstation is controlled by man but server is controlled by networrk of different computers

Yes you can , but there's not a section for it.

Suppose that we have two people, Person A and Person B. Person A wants to encrypt a message to send to B so that nobody else can read it.

Secret key cryptography works on the main principle that Person A would devise an encryption algorithm and create a key that can decypher it. Person A would then share the key with Person B. Thus when Person A sends B a message, Person B can use the key to decypher it. Since nobody else would know the key only Person B can decypher the message.

The obvious problem with this method that makes it impossible is that if Person A had a way to sharing the key with Person B without anyone else evesdropping then there would not be a need for encryption at all because Person A can simply deliver his message this way.

Therefore a far more practical approach involves using a Public-key system.

1) Start

2) Run

3) Cmd or Command Prompt

4) Type ipconfig /all

5) Write down Default Gateway (i.p. for Smoothwall)

6) Inject packets of information into it, or block it with an I.P. blocker

Facebook does not do background checks on individuals, so anyone, including criminals can gain access to Facebook. If they become aware that someone is using Facebook for criminal purposes, they will terminate the account but the criminal can just start up another account and continue using it. Convicted criminals can also be banned by a court from using Facebook for some period of time, but even so, those bans can be difficult to enforce since it can be hard to know what a person is doing at all times when they are on probation, out on parole, or otherwise not locked up. Those who are incarcerated may or may not have access - depending on what access they have to computers and how the filters on any computers they have access to are configured. Some places will block Facebook to protect those outside from the criminals. Others choose to allow it to give the prisoners some kind of social outlet.

To match the packet to the process that sent it.

i believe this is in the wrong section :P
