A Description Of A Password Attack

In this modern day and age of computing, networks are a huge part of IT. It is important now more than ever that data sent over any network, whether it be a LAN (Local Area Network) or WAN (Wide Area Network; The Internet) is kept safe, private (when required) and uninterrupted in

We are able to protect our networks from risk but never in totality, despite all our best efforts we are never 100% protected. “Of the two basic problems that rely on prevention, the first is that information security risks are multifaceted in nature, which implies that a virus arriving via e-mail, for example, may not only infect the local system but could also install a backdoor for unauthorized access to the network that can be connected to the utility provider of another country. The second problem is that true prevention requires the elimination of risk (i.e., stopping its occurrence) The only way to do that is to control most, if not all, components of the event. Not an easy task. That said, practical prevention is both the implementation of lessons learned and the application of knowledge gained to avoid the same fate in the future” (Ameri). Prevention requires reassessment of your security policy, learning and revamping of protocols to adjust with potential threats to maintain a healthy

In this report I will be describing the ways in which networks can be attacked, also be giving real life example of each of the below.

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.

Data protection and confidentiality; by making sure that all information and important documents are locked away and that you have passwords on the computers and not leaving them unattended without logging off first.

5. What are the three primary methods for implementing security on this network, as well as the advantages and disadvantages each?

We can say that the data and sensitive information that is sent over computer network be vulnerable to attacks by hackers.

Protecting the network would be considered the first and primary line of defense as mentioned by Boyles. (2010) At present, the only way to ensure the network is protected is to deploy a firewall appliance that performs stateful packet inspection. Let us consider another analogy. A firewall could be considered the same as a security guard at the entrance to a public building. The guard's job is to ensure only those individuals employed at the facility are allowed entry into the building. Usually accomplished by inspecting the credentials of the employees’ to make sure that are who they say they are. Those individuals that cannot produce credentials or are not allowed entrance into the facility are turned away. This is very similar to what a firewall does; it inspected packets coming into the firewall to ensure that they match a state which is maintained in the state table of the firewall. If they do them the packets are allowed to continue, however, if they do not match a state in the state table, the packets are dropped. This is an important feature of firewalls. To ensure that packets cannot harm the network and the computers on the network and to protect from attacks that originate outside the network, is in fact, one of the best solutions that can be proposed to ensure the security of the computers and network used by library

Firewalls protect sites from an exploitation of inherent vulnerabilities in the TCP/IP protocol suite (Wack, Cutler, & Pole, 2002). Additionally, firewalls help mitigate security problems associated with insecure systems and the problems inherent in providing robust system security for large numbers of computers. There are several types of firewalls, ranging from boundary routers that can provide access control on Internet Protocol packets, to more powerful firewalls that can close more vulnerability in the TCP/IP protocol suite, to even more powerful firewalls that can filter on the content of the traffic (Wack et al., 2002).

Encryption - apply encryption to the network with software and hardware solutions. For instance, software can be used to encrypt the financial records for anyone unauthorized to see the information, and a hardware solution can be used to build a VPN from any remote

To mitigate the security threat posed by ping sweeps and port scans it is highly recommended that firewall protection on all network hosts devices should be enabled to close any unused ports to protect them from unauthorized access. Also, is recommended that the use of a firewall server to protect the network from any outside intruders be used as well.

But like anything else, there must be a system in place to protect it from been abuse or uses it for the wrong purpose. For a security system, the first thing must be done is to encrypt the network it connected to, then change the default setting, turn off remote access-related features, update the firmware, and log out properly. But as the human factor, we cannot stop people from intentionally commit the crime. But with enough surveillances system in place and appropriate check and balance, those that abuse the system will eventually get caught by the system

In this digital age, securing a digital information is very important. One of the various ways to protect our digital information is authenticating properly. Likewise, among three factors of authentication, password is a factor that a user must know. There is always someone out there interested in grabbing our digital information, and a password can authenticate someone else to grab such information. Thus, it is important to be careful with protecting a password. Brute-force attack is one of the attacks someone can use to guess and match the password. Brute-force attack includes lot of dictionary words, so, it is important to create a strong password with words that are not in dictionary and include different special characters in password

By having proper equipment and competent employees to combat the possibility of sensitive information being

Network security has changed significantly over the past years. There is more and more data to monitor and analyze in order to detect the activity of your data and systems. Securing a network has many variables. Password authentication, network access, patches, anti-virus protection, intrusion detection, firewall and network monitoring tools are just a few of the things you can do to protect yourself.
