Lot2 Task 1 Essay

The purpose of this paper is to touch on the issue of Hacking. It will go into detail about the history, evolution, future and prevention of Hacking. In addition, this paper will discuss different types of hackers and their motivation behind hacking. This paper examines the major impact caused by malicious hackers and give modern examples of such attacks. To conclude, it will predict how hacking will be in the near future and give the precautionary measures Information Security professionals can take to mitigate the risk of being victimized.

The attack is carried out on a closed environment using a local web server to host the

! Deny any other traffic access-list 111 deny ip any any log The above commands illustrate the concept of our layer 3 design, and would need to be expanded and modified in a production environment. Let's now consider a workgroup subnet populated with desktops but no servers. Since we don't expect servers to be placed here, inbound tcp traffic is limited:

concerned with the protection of the server where the protection of the server constitute a large proportion of protecting your site

1.1.4 Requirements for a firewall at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone

The firewall providing the DMZ segmentation should allow only inbound packets destined to the corresponding service ports and hosts offering the services within the DMZ. Also, limit outbound initiated traffic to the Internet to those machines requiring access to the Internet to carry out the service they are

Firewall is the first step to good defense from intruders or attackers. Firewall security has gotten to be big business, because it’s can be programmed to fit Kudler’s network and infrastructure form the inside out. For one reason a good firewall is essential in the verification of all authenticated user either internal or external. One of the top firewalls out there is” Barracuda’s powerful, best-of-breed security products secure your organizations threat vectors – email, web applications, remote access, web browsing, mobile Internet, and network perimeters whether on premises or in the cloud” (2015). Having one of these and maintaining the firewall is critical to Kudler’s Fine Foods

Because Web servers are one of the few system components on a target network that typically communicates with third parties, they are frequently the targets of malicious attacks by intruders. Intruders can easily launch automated attacks against thousands of systems simultaneously to identify the relatively few vulnerable systems.

This presentation discusses an incident known as a denial of service (DoS) as well as an intrusion of the clinic’s network systems. A denial of service (DoS) attack is designed to shut down services which a business needs to operate. This incident caused widespread slowness and outages to internet services and affected the clinic’s capability to properly treat its patients. In this presentation, the incident is examined. The processes to detect, analyze, contain, eradicate and recover from the incident are the focus of the presentation. Once the incident investigation was complete, special consideration was made as to what was learned and how clinic staff can help protect the clinic’s ability to properly serve its patients.

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

A border gateway should be established to control the traffic that is allowed to cross the border from any direction. The border gateway will block communications from any IP addresses where problems have arose in the past. The gateway could also block any computer outside the network unless permission is given from inside the network. Packet filtering can also be enabled to block or allow packets from specified protocols (Palmer, 2003).

Each approach has its advantages as well as disadvantages. Sometimes it is even impossible to choose freely as placing a server in front of a firewall is simply not possible or not

There were a number of factors that contributed to the breach, which had they been addressed or had corresponding mitigation responses in place, would have reduced the likelihood that the breach would have taken place, or at a minimum reduce the impact of the attack. These items range from policy related issues, technology implementations, and security management and maintenance. Although I believe a number of these areas were in the process of being addressed, based on the information gathered regarding the details of the incident, it appears that it was still in many areas insufficient and would not have prevented an incident even if there had been more time available to perform the implementations.

Web applications are nowadays serving as a company’s public face to the internet. This has created the need to identify threats and attacks directed to data servers and web applications. Hackers exploit vulnerabilities in input validation and authentication affecting the web application in order to gain illegal access and disclose sensitive data or manipulate it to their benefits.

The always and ever increasing quantity of products with IP routers are incorporating packet filtering as a tool to help in improving the network security if utilized in the proper way, packet filtering is a great tool for a network’s security or networks administrators that are security conscious but in order for it to be used effectively one must have an in-depth understanding of its many capabilities and weaknesses, advantages and disadvantages and what type of particular protocol that the filters are being applied to. This paper begin by defining firewall and identifying the different types of firewall then goes into Packet filtering describing some of the characteristics and some of the application protocol then the paper identified
