Storage Of The Packet Filtering Essay

Why would an information systems security practitioner want to see network traffic on both internal and external network traffic?

Networking is part of our everyday lives now. Weather is us using our phones, computer, using GPS for directions, watching 3D movies and TV’s or in our work environments. Network Security has become search a big issue since our day to day live started to be more involve with us. These problems involve in all type of shapes and forms where some of these issues are cyber attacks, physical attacks, or abuse of policies. People are really exposed due to the amount of internet activities we have going on in most of our networks. There are two fundamentally different when it comes to networking, the data networks and the synchronous network comprised of switches. With that being said there are also

In this report, we analysed and evaluate the project management of the case: The case, The PCNet Project (A): Project Risk Management in an IT integration Project. We had look into the project definition phase of the PCNet project and discuss some of the problems that emerged during the project in relation to project definition phase. We also evaluated the role of the PCNet project manager and discussed some of the core skillsets demanded by the job role. The risk management aspect of the PCNet project was also studied in our report. Lastly we made recommendations to address the dilemma faced by Jack Muller, the project manager for the PCNet project.

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

being filtered and the clients are more likely to receive malicious software in the form of

Paraphrasing (Stallings, 2007) the function of routers is to get the packet to a destination network. The router reads the header created by the Network Layer of the protocol stack on the source computer. The router can be configured to filter by protocol, source

To reduce the risk of these types of attacks, routers should be hardened, packet filtering controls should be used and routing information should be controlled.

Which layer of the OSI reference model handles logical addressing (IP addresses) and routing traffic?

A proxy server that acts as an intermediary for requests from clients seeking data from other servers.

Within the United States, the first amendment, freedom of speech includes the cyber-web. However, the government may try to examine personal information to protect its citizens from planned terroristic activities. Even so, these terrorists are allowed to say whatever they want, but it does not mean it will be ignored and not taken as a literal threat by the government. Throughout other parts the world, however, countries rely on communicating through means of the internet as ways to spread propaganda. In countries like China specifically, their government censors its citizens to prevent the spreading of propaganda or other radicalism. However, due to the fact that China’s strategy is so

There are two types of Internet Protocol (IP) traffic, such as Transmission Control Protocol (TCP) and User Datagram Protocol (UDP). Some of the features that UDP possesses that are not provided by TCP/IP. First, UDP is a connectionless protocol (No handshake), which means packets sent from one node to another without making sure whether any packet may be lost during the transfer. TCP, on the other hand, makes sure to establish a connection in order to send the packets from one node to another without losing any packets. It is also known as handshake process, where nodes synchronize (SYN),

Firewalls are also important because they are a single point where you can impose security and auditing. If someone attacks a computer system by dialing in with a modem, tracing the perpetrator is impossible. In contrast, the firewall can act as an effective phone tap and tracing tool. Firewalls also provide an important logging and auditing function, summarizing topics such as the kinds and amount of traffic that passed through it and how many attempted break-ins occurred recently.

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.

As noted earlier by noted by Steinke (2001), TCP is responsible for the provision of a reliable and yet connection-oriented byte-stream packet delivery. The TCP/IP protocol is a reliable protocol. This is due to the fact that the TCP/IP acknowledges all of the packets (segments) that one sends to the receiver. The reliability is achieved via a mechanism known as Positive Acknowledgement with Retransmission (PAR). TCP is therefore reliable due to the fact that it provides a seamless and yet reliable delivery of data. It achieves

In an e-commerce world, organizations are susceptible to hackers and intruders. Thus creating the information technology protection systems which is used to reduce the possibility of intrusions from occurring. Intrusions occur by uninvited outsiders (sometimes intruders can be internal users like employees) who try to access an organization’s information system using the internet with the intent to gain competitive advantage of some sort. Organizations depend on security technology to avoid loss from security breach, as well as to improve their efficiency and effectiveness. However, firewalls are also vulnerable to errors, and implementing a security technology comes with challenges and critical decisions that can possibly cause a financial burden on the organization if done without seriousness and commitment. “Information security is about managing risk, and managing risk is about discovering and measuring threats to information assets; and taking actions to respond to those threats” (Al-Awadi, & Renaud, 2007, p.3). This paper will discuss a few aspects that are involved with firewalls and intrusion detection systems.
