Ping Sweep And Port Scans

We have been engaged in business for some time, and have been very successful, however we need to re-examine our network configuration and infrastructure and identify that our network defenses are still reliable, before we make any changes. We need to take a hard look at our current configuration of host, services and our protocols within our organization. Data from a large number of penetration tests in recent years show most corporate networks share common vulnerabilities. Many of these

Protocol capture tools and protocol analyzers are important tools for an information systems security professional. These utilities can be used to troubleshoot issues on the network. They can verify adherence to corporate policies, such as whether or not clear text privacy data is being sent on the network. They can be used to test security countermeasures and firewall deployments and are needed to perform audits, security assessments, network baseline definitions, and identification of rogue IP devices.

Now a day, companies are focusing and investing more on IT security, where the company’s and customers’ personal and financial information managing and storing. Certainly, more cost involves in this process. Companies who failed in security breach prevention paid and paying huge amount. Example for this is Target. This multinational grocery stores company’s data breached in 2013 this affecting its business. Furthermore, by 2015 nearly 1000 Target employees lost their jobs and the company is facing legal suits from bankers and customers.

While all of these technologies have enabled exciting changes and opportunities for businesses, they have also created a unique set of challenges for business managers. Chief among all concerns about technology is the issue of information security. It seems to be almost a weekly occurrence to see a news article about yet another breach of security and loss of sensitive data. Many people will remember high profile data breaches from companies such as T.J Maxx, Boston Market, Sports Authority, and OfficeMax. In the case of T.J. Maxx, a data breach resulted in the loss of more than 45 million credit and debit card numbers. In many of these incidents, the root cause is a lack of adequate security practices within the company. The same technologies that enable managers can also be used against them. Because of this, businesses must take appropriate steps to ensure their data remains secure and their communications remain

Usually, network security issues are of major concern for all businesses that want to keep the affirmation they are usually dealing with under strict confidentiality. These issues are not very recent, ever since information was transferred among senders and recipients, data transition has been prone to, so as to speak, attacks in order to undermine the protection and to reach out relevant or useful pieces of information. In essence, these attacks are the results of tough competition. Even though network security issues are these days associated with computerized solutions, as a matter of fact,

Finally, IT organizations must manage the information accordingly, ensuring privacy and security as well as appropriate retention as dictated by both business and legal or regulatory requirements.

The use of Wireshark and Network Mapper (Nmap) vulnerability assessment tools will identify potential flaws in the Microsoft and Linux operating systems. In order for an attacker to breach into the computer system; the attacker needs to either be using the Wireshark or Nmap tool. First, a machine needs to selected by using a variety of techniques like port scanning and so forth. Once the targeted system has been identified, the tool is initated and the attacker can sweep through the entire network for weaknesses and open network ports.

All employees and businesses need to be aware of the potential danger to information security and privacy. It needs to be top priority within a company’s daily operation. Employees need to be more concerned of the safe keeping of their information. With all the advancements in technology there are many ways to ensure security and confidentiality of all employee and company information. Data storage options, limiting personnel access and enforcing processes and procedures are just a few.

Ping sweeps and ports scans are a common ways for hackers to probe a network and attempt to break into it. Although network probes are technically not intrusions themselves, they should not be taken lightly—they may lead to actual intrusions in the future. In the information that follows, I will provide a standard definition of a ping sweep and port scan, the possible uses of the two, and the prevention methods which are in place in our company to combat ping sweeps and port scans of our network by would be attackers.

An important consideration of an information or operating system of a business or organization is to have a security system that protects information, data, and integrity of the company’s sensitive information and records. If a business or company does not have adequate security, financial, sensitive, and classified information may be compromised and prone to possible viruses and malware, hacking, or at risk of a cyber-attack to the company’s data resulting in possible

According to Kizza (2013), the rapid growth of networking has led to increased security risks. Many of these risks are as result of hacking, improper uses of network resources and network device vulnerabilities. Awareness of the various weaknesses and vulnerabilities is vital to the success of current networks (Kizza, 2013).

In the modern business world, effective use of information systems is vital for businesses to stay afloat. But it is just as important that those systems remain secure. Information Systems Security means "incorporating system analysis and design method, manual information systems, managerial issues" and also assessing "both societal and ethical problems" that could affect employee behaviors regarding security (Norman & Yasin 2010: 231). Impingements upon the security of information systems can impact employees, company operations, and customers (which can have a negative effect upon the company's reputation and future profits).

The business world is increasingly dependent on technology to supply information and communications facilities to staff, partners, and customers. Securing organizational information and the systems that are used to manage and transmit data has become a high profile function. Failure to secure information can have a severe impact on business

The overall security for the networked environment is weak, and the team was able to move quickly through the information system and gain system level access on most of the attached hosts, within the scope of the penetration test. Had the organization been equipped with a firewall, the ability to conduct the following test would have become a more difficult task. However, because packets can move freely, the systems provide more data than they should. Secondly the team identified the requirement to segment the network. In its current configuration, Appendix B, the organization is easily exploitable. Coupled with a firewall, a segmented Local Area Network, and firewall to filter the local area traffic, the organization becomes a more

Logical and physical view of the network helps administrators and engineer to identify possible security issues. Hackers try to obtain access to highly sensitive data by first creating map of the network
