3. Which application is used for Step #2 in the hacking process to perform a vulnerability assessment scan?

The most reliable secured process has an endless relation between hardware and software communicator. There are many VoIP services that are been coming into the existing market for the users to make cheaper calls which would be useful for everyone like Fruing, Truphone, Vopium. There are two types of security linked or associated with the IP. There are certain ip key Exchange, which has unique key generator for protocol exchange and budget management. It has the features reliable communication of communication between two unique devices which initiates an encryption useful algorithm, a key based authentication method, and extracted group theory information.

Our company is looking for security threats inside and outside their network. The best way to see what our network is vulnerable to is to use penetration testing (pen-testing) to find the leaks in and out of our network. Penetration testing is a network security approach that simulates an attack from an intruder trying to get unauthorized access to the infrastructure. With this type of testing the intent is to discover flaws in the security settings of the system before they can be exploited. Information Assurance Research Corporation (IARC) should conduct penetration testing on a regular basis, so we have the ability to locate weaknesses in the hardware and software, check the security controls currently established and determine if the

Penetration testing is the attempt to identify security weaknesses within the IT infrastructure of an

Discuss approaches to a penetration test and vulnerability scan in terms of black box, white box and gray box tests.

The penetration tools provided in this document allow us to review our network from a security standpoint. This paper focused predominantly on phase two of a penetration test, the exploitation phase; however, a successful penetration test typically starts with the reconnaissance phase. In this phase, the tester attempts to gain as much information about the target company and its network as possible. He or she will test the physical infrastructure (how do people gain access to the building?) and other organizational aspects of the company to find a weakness and a way to get in. Also during this portion of the test, the penetration tester will use tools such as NMAP, whois.com, and other resources to obtain information regarding the network

The WAN will link all of the site networks together which will in turn boost the network speed and the way employees communicate. The communication aspect of the new network will incorporate a VoIP system and will be managed at one central location. “The great thing about VoIP is that it taps additional value from the already existing infrastructure without additional costs” This will provide the highest quality of phone network will saving on the cost of out phone services.

When designing a WAN, numerous factors must be considered. Organizations attempting to connect multiple factories or offices and remote personnel must take into account a number of variables that will impact overall costs and network functionality. When designing and implementing wide area networks (WANs) that integrate voice, video,

This deals with doing your homework. Researching your target is the most important part of an attack. Once your target has been pick out, probing for possible vulnerabilities within their network is performed. With the use of common tools found on the internet like DNS and ICMP, Standard and customized SNMP tools, Port scanners and port mappers, and Security probes to exploit a potential target.

“Keystone Computers & Networks, Inc. (KCN) is a company that sells and installs computer workstations and networking software to business customers. The CPA firm of Adams, Barnes & Co. has audited the financial statements of KCN for the past three years. The case illustrates selective audit planning working papers that were prepared by the staff of Adams, Barnes & Co. for this year’s audit.” I will be listing the order in which I would perform this audit and I will decide if I should select the client and focus on the key audit objectives while applying the audit risk model.

In the current society, business, organizations and government are very dependent on computers and Internet. Adequately protecting an organization 's information assets is a requisite issue. Many organizations have deployed security software or devices, such as firewalls or intrusion detection systems, to help protect their information assets and to quickly identify potential attacks. IBM Systems Journal states that "some organizations came to realize that one of the best ways to evaluate the intruder threat to their interests would be to have independent computer security professionals attempt to hack into their computer systems" (IBM 2001). This might be a good way to evaluate the system vulnerability. However, to allow a penetration test team break into their systems, the organization may have faces some risks. For example, the penetration test team may fail to identify significant vulnerabilities; sensitive security information may be disclosed, increasing the risk of the organizations being vulnerable to external attacks (The Canadian Institute of Chartered Accountants). Some organization even send their system administrator to be trained Ethical Hacking as a career course in Tertiary

1 The employees from the newly acquired company Skyhaven can have access to sensitive data of Code Galore because both servers have vulnerabilities that could allow an attacker to gain unauthorised remote privileged access it can be solved by using biometric security or face recognition methods as access methods that would make the data highly secure but since the company has cash crunch they can opt for access rights and permissions to the required users.

4) Against the background of your answer to questions #1 and #2, how should Cisco distribute VoIP products? Through voice VARs? Data VARs? Or both?

d. “The auditor's reliance on substantive tests to achieve an audit objective related to a particular assertion may be derived from tests of details, from analytical procedures, or from a combination of both. The decision about which procedure or procedures to use to achieve a particular audit objective is based on the auditor's judgment on the expected effectiveness and efficiency of the available procedures. For significant risks of material misstatement, it is unlikely that audit evidence obtained from substantive analytical procedures alone will be sufficient (PCAOB, AS 2305.09).”

Voice over Internet Protocol is a technology that allows telephone calls to be made over computer networks like the Internet. There are several implementations of VoIP in the internet today. Many major telephone companies like AT&T have moved over to VoIP completely. It is still not clear how the performance varies with different network conditions, considering that the Internet does not provide QoS guarantees. The main objective of this paper isto evaluate the performance of G.711 VIOPcoder for different networks. Wired, Wireless Local Area Network (WLAN), Worldwide Interoperability for Microwave Access (WiMAX) and Universal Mobile Telecommunication System (UMTS) networks were implemented in OPNET Modeler The quality is compared using different QoS parameters like end-to-end delay, MOS, throughput and jitter. The VoIP codecs used in the measurements of QoS are: G.711,723.1 AND 729A. Simulations showed that G.711 is the best schemes that provide high quality of voice in Wireless Local Area Network (WLAN) communications .The results analyzed and the performance evaluated will give network operators an opportunity to select the codec for better services of VoIP for customer satisfaction.
