He can use the names or phone numbers listed in the DNS to gather more sensitive data. Internet Protocol Address range can also be of useful to the attacker. By knowing the IP range, the attacker can port scan and identify active machine on that network. Although IP address range finding is imposable to protect from hackers, there are still counter measures
Record the steps that you follow for the process, and record the network location that is mapped to the letter you choose. Exercise 2.2.4 What are the drawbacks of using a networked drive for storing important documents? Use your textbook and the Internet to support your conclusion. Exercise 2.2.5 For this exercise, you will create a link to a web resource on your desktop. You should record the address of the link that you create.
Another user makes destructive changes to one of your spreadsheets. 16. An attacker can access the Web server. running on your domain server computer. and run the sample programs.
Case Study Week 1 Katherine Vega DeVry University SEC 280 Ahmed Azam November 4, 2012 Ping Sweeps and Port scans are related programs or tools, called network probes, which allows a person to not only gain access to online computers, but also to determine what services are being run on them furthermore to get an edge on compromising information. This network probes aren’t inherently malicious on their own as they are used by network administrators for the aforementioned diagnostics, however in the wrong hands they could pose a security threat. This is not meant to cause fear but to bring about awareness to computer users. As the programs are most commonly used for network diagnostic and determining other network problems. To begin
4.4.3 Noise SMF Crosstalk Coaxial Interference Coaxial Op en (Open Circuit) UTP Short (Short Circuit) MMF Break UTP 4.4.4 I first start with my anti-virus to run any scans, after that I go into my device manager and click the network adapter. I then will go into my general tab and click trouble shoot. 4.4.5 Some of the common strategies for trouble shooting from top down starts with are you able to view a web page in your browser, can you se nd or receive email and/or are your username and password correct, and are your Interne t Explorer connection settings correct. If none of those are an issue you take it a little further. Is there a firewall configured on your computer, is your firewall block ing ports, if you turn off the firewall does it resolve your problem?
It uses a variety of algorithms to provide authenticity and integrity of the data, and uses session keys. Client based SSL gives authenticated users access to the company’s network as if it was part of the LAN. Clientless SSL would provide the user with a web browser address where they will find a login page. This means that the worker can still access company files without a company regulated device IPsec is a secure bulk of open standards created by IETF. By not relying on a specific algorithm, it allows the suite to be modified in the future to support even more security methods.
96 LAB | Manage Linux Accounts LAB – ASSESSMENT WORKSHEET Manage Linux Accounts Course Name and Number: IS3230 Student Name: Mark Anthony Instructor Name: Mr. Randolph Lab Due Date: 23JUL15 Overview In this lab, you created new user accounts on a Linux virtual machine. You also granted administrator privileges to one of those user accounts. Later, you created two new security groups, added user accounts to those groups, and finally you deleted two of those user accounts. These tasks helped you understand different account types and the use of security groups on a Linux machine, and understand the security controls for those accounts. Lab Assessment Questions & Answers 1.
I believe that this concern should be left to the company owners as individuals. Personally, I don’t agree with the fact that the way America gets other countries to bend over backwards is by threatening to cut off financial business ties. I feel that America is trying to gain control of the world by doing so. However, I do agree that any sort of discrimination is unethical and should not be tolerated. That is something that each countries governments should have control over, not a foreign country that threatens to cut off business associations.
The risks that exist would come from a suspecting end-user, potentially some form of malware, that would be installed through an open port, thus causing the integrity of a machine on that network to be severely compromised (Lawrence, 2000). Ping sweeps and port scans are two direct unsuspecting threats that, like other cyber threats, are not to be ignored. The ease of gaining access by using these threat sources is something that a business should be aware of and be prepared to address when faced with being at the end of a cyber-attack. Implementing appropriate policy to counteract such a malicious and serendipitous attack on network vulnerabilities should be considered as an additional failsafe. Protection is the key and showing extra caution can at least reduce the
Use of this technology has created an avenue for industrial espionage, proliferation of malware exploits and numerous other cyber-attacks. Conduct research on this growing technology, include the different scenarios in which it is being used in the workplace, security threats and the mitigating controls that are being used to reduce the risks. Public Key Infrastructure (PKI): The Public Key Infrastructure is a prominent concept in the information technology arena and is based on public/private keys and digital certificates. It operates as an environment in which trust is paramount between users of the infrastructure. In this paper, discuss the core concepts of PKI - authentication, confidentiality, integrity and non-repudiation.
