Computer Backupss And Nups

Also information systems assist with making decisions and business processes by formulating strategic plans and make decisions for the organisation longevity and prosperity. Additionally information systems add controls to employee processes, ensuring

Identification is the means through which a user is associated with and gains access to an account. The most common form of identification in use with computer systems is through the use of a username. Other systems use Common Access Cards (CAC), smart cards, or tokens combined with a pin code that allow for access to a system. More complex, high security systems might use some form of biometric to associate a user with an account and permission set. Biometrics include: fingerprint, iris scan, facial scan etc.. something that is unique to the particular person that cannot be easily altered. Identification allows for the tracking

Firewall: A firewall is a software or hardware-based network security system that controls the incoming and outgoing network traffic by analysing the data packets and

A backdoor is “a means by which a developer or user reenters a computer system at a later date and time, without going through the normal security processes”. When someone use, or created a backdoor they are trying to hide evidences of their unauthorized access to the system. What is intrusion detection system? Intrusion detection system or IDS is “a computer security system that is intended to detect attacks on systems and to detect the unauthorized use of such systems, networks, and related resources”. Another thing we can find evidence from is the

A firewall protects networked computers from intentional hostile intrusion that could compromise confidentiality or result in data corruption or denial of service. It may be a hardware device or a software program running on a secure host computer. It must have at least two network interfaces, one of the network it is intended to protect, and one for the network it exposed

Segregation of affected system as soon as possible and investigation begins to establish the amount of damage.

Often attacks are based on software bugs that a hacker can use to give himself or herself super-user status. Also one can get a copy of the password file (which stores user names and encrypted passwords and is often publically accessible) and either do a brute-force attack trying all possible combinations, or encrypt a dictionary and compare the results to see if anyone choose a password that is a dictionary word.

Passwords are usually combination of strings, characters and numbers used for authenticating the user and provide the access to utilize the resources/data. There are different operating systems and each of them has different options to enable the passwords.

Network Intrusion Detection: Software exists to watch traffic on your network to search for malicious intent. Is an Intrusion Detection System going to be implemented? An IDS is not a fire and forget type system. It requires constant monitoring. Smaller organizations will be overwhelmed by the amount of information it produces.

This type of network is designed to provides a secure, encrypted tunnel in which to transmit the data between the remote user and the company network” (Beal). VPN uses encryption to provide data confidentiality. Virtual Private Networks makes use of encryption and special protocols to provide extra security.

Having a backup of data is important because if the data becomes corrupted or lost you will have it copied and stored so that you will still have it in future for if something goes wrong.

The goal of intrusion detection is to monitor network assets, detect anomalous behavior, and identify misuse within a network (Ashoor, Gore, 2011). An intrusion detection system (IDS) is a device or software application that monitors network system activities for malicious activity or policy violations and produces reports to a management station (Kashyap, Agrawal, Pandey, Keshri, 2013), additionally there are three types of IDS:

A firewall is a system or group of systems that enforces an access control policy between two or more networks. The means by which this control is accomplished varies widely, but in principle, the firewall is a pair of mechanisms, one that blocks traffic and one that permits traffic. Some firewalls emphasize blocking traffic, while others emphasize permitting traffic. The most important thing to recognize about a firewall is that it implements an access control policy. If you don't know what kind of access you want to permit or deny, or you let someone else or some product configure a firewall based on judgment other than yours, that entity is making policy for your whole organization.

Firewalls is categorized as a preventive control which is used as a defense shield around IT systems to keep intruders and hacking from occurring, whereas, an Intrusion Detection System (IDS) which is categorized as a detective control is used to detect intrusions that have already occurred (Cavusoglu, Mishra, & Raghunathan, 2005). However, IDSs are not

Backup and restore points backing up your PC is very vital if you don’t wish to lose any of your information through corruption or the viruses. You can easily backup your system through a partition on
