...Assignment 1: Attack Methodology and Countermeasures Terrance Moore Professor Siplin Perimeter Defense 10/31/2013 When you are utilizing security features in an application, consideration should be given to the design, implementation, and deployment. It would helpful if you understand how a hacker thinks and then utilize the tools a hacker would use. Today, every company is becoming completely networked, through the exchanging of information on desktops, laptops, tablets and smart phones. Thinking like a hacker and understanding a hacker’s tactics and scams could make you aware and become more effective when applying countermeasures. There are several methods for carrying out ethical hacking, the most common are limited vulnerability and penetration testing. Limited vulnerability analysis, focus on entry points to gather critical systems and data. By understanding the basic approach used by hackers to target organizations, you will be better equipped to take defensive measures you will be better equipped and know what you are up against. There are steps involved in scanning a network, the following points will highlight them. 1) Check for live systems, 2) Check for open ports, 3) Fingerprint the operating system, 4) Scan for vulnerabilities, 5) Probe the network. Tools that can be used to detect scanning threats and countermeasures that a company can use to deter and avoid vulnerabilities are as follows. “Spoofing user identity -use strong authentication for passwords...

Introduction: Maintaining a proactive approach on security requires that an organization perform its own hacking footprinting to see how much information is available to potential hackers. Some organizations do this using internal staff; however, it is much more common to see organizations hire external security consultants to perform these types of security reviews. This allows a truly unbiased outsider to attempt to gather as much information as possible to formulate an attack. Assume that you have been selected as the security consultant to perform a comprehensive security review for an organization of your choosing. Ensure that the organization that you select has a public website that you can access and at least one web application that you can use for this task. You will review the security...

...26, 2014 Ethical Hacking Ethical hacking is used to describe hacking performed by a company or individual to help identify potential threats on a computer or network. An ethical hacker works passed the system security to detect the vulnerabilities or weak points of a company’s network. Then this type of information is used to improve the company’s network from the bad hackers who exploit the company in a destructive way. In 1960s, U.S military began testing their own IT systems, but when Dan Farmer a security expert from San Francisco and a security programmer at the Netherlands University of Eindhoven had posted the techniques they used to gather information to the Usenet, that could have compromised the security of a number of target networks(Langely). Their goal was to raise the overall level of security on the internet. Dan farmer and Eindhoven were elected to share their work freely on the internet for others to learn. Eventually, they gather up the work they used and developed a program called Security Analysis Tool for Auditing Networks (Langely). This tool is used to perform an audit of the vulnerabilities of the system and how to eliminate the problem. The concept of ethical hacking started emerging in 1993 (Langely). According to some, ethical hacking does not exist and they feel hacking is just hacking, no matter how you put it. Therefore the one that is doing the hacking is a computer criminal. This is not the case, so in order for hacking it to be “ethical...

...Hacking and Countermeasures IS4560 Unit 1 Assignment 1 July 26 2016 Hacking and Countermeasure Here are some of the top threats described in the whitepaper and why the threats are important issues and how these threats have changed or are changing. The main issues that I found were Web browser vulnerabilities and SQL-injection attacks. These types of threats are found often and hackers exploit them all the time. One of the most known browsers to get exploited is internet explorer. “In the case of the Hydraq attack, a previously unknown vulnerability in Microsoft® Internet Explorer® and a patched vulnerability in Adobe® Reader® and Adobe Flash® Player are exploited to install the Trojan.10 Once the Trojan is installed, it lets attackers perform various actions on the compromised system including giving them full remote access. Microsoft has had to release patches for Internet explorer. Attacks can originate from malicious websites as well as legitimate websites that have been compromised. So in the end it doesn't really matter which web browser you are using the end result will be the same if their vulnerabilities are not updated. According to statistics from 2014, there was an increase in the market share of Chrome, Firefox, and Safari at the expense of Internet Explorer over the course of the year. The second most widely exploited attack was the downloading of a suspicious PDF, this was really affecting those who...

...Attack Methodology and Countermeasures Strayer University SEC420 Professor Gillen July 24, 2015 Attack Methodology and Countermeasures When most people hear the term “hacker” they think of an evil person committing crimes by hacking into their computers to steal, destroy and/or steal identities. This is so in some cases, but not all hackers are bad. Hackers are merely curious technically skilled individuals who gain unauthorized access to computers, networks of various companies, organizations and individuals. Good hackers are considered white hat hackers. They are the ones, who are hired to break into systems as a way of testing the vulnerabilities and security issues that may be present in the computer system. Consider this: company XYZ, a mid-sized corporation, is in the middle of satisfying their regulatory compliance needs. The manager of security at the company has been tasked by the CIO (Chief Information Officer) to report on the company’s current security posture. If the manager decided to outsource an ethical or white hat hacker in attempt to test their security measures. Over the course of this document various things the third party hacker would need from the company, things he or she would provide to the company and some predictions for the tests. In order to exploit the targeted systems the initial steps to gain as much information as possible about the targets. In this case, the manager is the contact in which questions may be posed. The hacker would...

...the ones I deal with currently are work station, user domain and remote access. In any environment that you work with any of these 7 domains countermeasures are needed. It’s very important to make sure your network is secure and there are quite a few actions to take to ensure that it is safe as possible. Although no domains are 100% secured it’s always good to make sure all updates and patches are up to the most recent. I will also name a few other ways to protect certain domains in a typical IT infrastructure. Some countermeasures to take for user domain are making sure to have all users aware of security. Also have restricted access for a company’s terminal server and observe abnormal employee activity. Anti-virus is also needed to make sure the computers servers aren’t infected with malicious programs that cause loss in important documents. With a work station you can add a firewall to prevent unwanted traffic from infiltrating the network. Ensuring that your workstation has the latest service packs and patches update will also help protect any holes that could lead to hacking. Also with remote access it’s good to make sure only that person has access to certain files and must keep their password secure and not make a weak password so it does not get compromised. All these countermeasures serve as security and deterrents for any possible ways threats by people or viruses can cause damage to your typical IT...

...configure properly, and people who configure them may not know the current threats and attacks. For example, an administrator maybe working on some task and might leave something open in a firewall where attackers can enter through. Some firewalls have the vulnerability that enables attackers and be defeated. By identifying the network components, you can evaluate their vulnerabilities. These vulnerabilities can have flaws in the technology, configuration, or security policy. Vulnerabilities can be fixed different ways, applying software patches, reconfiguring devices, or deploying countermeasures such as firewalls and antivirus software. Threat is when people take advantage of vulnerability and cause a negative impact on the network. If threat occurs it needs to be identified, and the associated vulnerabilities need to be addressed to minimize the risk. As of today, most of the hackers are interested in hacking services such as HTTP (TCP Port 80) and HTTPS (TCP Port 443), which are open in many networks. By using access control devices, they can detect malicious exploits aimed at these services. Now these days applications has improve and very hard for hackers to get into but the technology need to stay up to date and be more intelligent. The attack methodology requires firewalls to provide not only access control and network protection, but also to understand application behavior to protect against attacks and hazards.

...Ethical Hacking – Is There Such A Thing? Alexander Nevermind Nelson Stewart, PhD CIS 324 December 9, 2011 ABSTRACT ------------------------------------------------- When someone hears the word hacker, many things come to mind. Bad, thief, terrorist, crook and unethical are some words that may be used to describe a hacker. The reputation of a hacker is well deserved as many company networks have been compromised with viruses and spyware causing untold millions in damage, the theft of sensitive consumer information such as Social Security numbers and financial data and the unauthorized access of classified government information. To combat these issues, many companies employ individuals called ethical hackers who, by their direction and supervision look for vulnerabilities in network systems. There are naysayers who bristle at the term “ethical hacker” saying that a hacker is a hacker but those who hold such views could be missing the point. These subjects will be discussed in detail later in the text. ------------------------------------------------- Is there such a thing as “Ethical Hacking?” Define ethical hacking and support an argument in favor or against the concept. Consider who might believe/use ethical hacking and discuss if hacking, even for the purpose of protecting human rights, is ethical. You should extend the paper beyond the topics suggested in the questions within the paper description. Ethical hacking does exist, in fact, companies...
