Introduction
As we know internet is still growing and e-commerce is on its advance. Near every electronic device may have its own IP address, which are connected more and more by internet, wireless networks and devices. Therefore for securing services, system and networks some efforts are need to be spended. So security is a topic of concern. Ethical hacking is nothing but testing your computer and networks. It is necessary to test for security vulnerabilities before it is being exploited by a bad guys or hacker. There is a silent war on the internet between bad guy and a bad guy. Good guys are the ones who are trying hard to secure the information and the bad guys are ones who are trying to get prohibited access to these information. As security is a never ending process, there is no fire and forget solution. Securing an information technology environment is not simple just like a bunch of actions which can be taken and then forgotten. It is not simple to maintain a high level of security. Many questions arises everyday- Are we secure? , and answering such question is not simple. It is not able to say, by help of which factors we can state that environment is secure or not. As we all have heard about the hackers, so who are these hackers. Is it important to know about them? As most of us are suffered the consequences of hacker actions, we will try to understand the hacker objectives, ethical hacking process, different types of hacker etc. This all will be explained in this
41. Do we use automated tools to assess system/network vulnerabilities?
With widespread use of internet services, the network scale is expanding on daily basis and as the network scale increases so will the scale of security threats which can be applied to system connected to the network. Viruses and Intrusions are amongst most common threats that affects computer systems. Virus attacks can be controlled by proper antivirus installation and by keeping the antivirus up to date. Whereas any unauthorized access in the computer system by an intruder can be termed as Intrusion and controlled by IDS. Intruders can be grouped into two major categories which are external and internal Intruders.
In this leaflets I will be talking about how the network can be attacked, One way the network can be attacked is DOS and what this stands for is Denial of service, this attacks the network by overflowing the network with useless traffic, the result of this overflowing cause the network to slow down significantly, and even can crash the network if it overflows too much. The damage that is can do to a business is huge they can lose a lot of money to fix the issue. The weird thing is that the hacker does not even benefit from this attack. The second way the network can be attacked is backdoor this attack is basically when you can access a computer program that side-steps security, the hackers use backdoors that they made or backdoors they found,
When accessing this information, the black hat hackers also sell this information to other hackers/ criminals, which are then used on blackmailing the organisation for money. Black hat hackers can also include planting a keystroke of monitoring the programme of being able to steal data from the organisation or launching attacks to disable access to
1:- Penetration Testing It is the process of trying to gain unauthorized access to authorized resources, systems and applications. Penetration testing is also known as an ethical hacking as “breaking into your own system to see how hard it is to do”. Network security measurement is the task which aims at supplying the scanning to check the security flaws and security threats in applications and networks. 2:- Why perform penetration testing • Test network or system using the tools and techniques that attackers use.
To reduce the risk, companies or schools should use multi authentication. 8. Natural disaster Can result in loss of important and confidential information of businesses Back-up the systems on regular basis to avoid losing all of the data. 9. Unauthorized user gain the access to your workstation This risk could be loss of your personal information and data on your computer Should monitor the access to your workplace.
Software updating If you want to protect your computer from any malicious activities, therefore, you should update your computer security software regularly. It is very important to update a software security software because some weakness software may allow a hacker or viruses to gain access to your computer. Moreover, update a software can able to make your computer faster. If you do not update the security software that means there will be changes to get attacks by hackers and viruses so you should update a security software regularly.
Chris McCandless, whose story is analyzed in Into the Wild, by Jon Krakauer, is a young adult who decides to leave his known habits and material belongings behind and live a completely self-sufficient life in the wilderness, a choice which ultimately leads to his death. In doing that, he also forfeits his family and friends. With that in mind, a question can be posed regarding the ethics of said behavior. As a childless, single and financially independent man, Chris McCandless has absolute ownership of his body and thus his decision to continue doing a sport that he knows can kill him is ethically defensible.
The first step that the auditor should take is to gather as much information about any security procedures and policies that may have been in use following the information collected from the records available. Since each policy may have a different aspect that it works on, the findings from the audit may present evidence that may be vital in identifying the existing procedures or the absence of any policies or procedures. The existence of policies and procedures enables a company to reduce the occurrence or the impacts of a given risk. The lack of such policies may lead to reduced risk management
They are just leeches who take other people's property without consent, criminals lurking on the internet. I have been hacked a couple of times through online software, where I have downloaded software then viruses attack my system, usually a pop up box appears saying “You have been hacked” - they are the equivalent of 10 year olds. Crackers are just a bunch of kids who have nothing to do so they mess someone else information or steal
- Respecting privacy: You should treat the information you gather with complete respect. All information you obtain during your testing must be kept private such as from Web application log files to clear-text passwords. - Not crashing your systems: One of the biggest mistakes is when they come up with crashing their systems while trying to hack their own systems. The important reason for this is poor planning. This is because the testers have not read the documentation or misunderstand the usage and power of the security tools and techniques.
New technologies that people had never imagined a decade, or even some decades ago, are now expanding and changing all our lives. Taking smartphones as an example, people in old time had never imagined that small, tiny box could enable people to bring smart computer to everywhere. Yet, smartphones are now completely embedded into our lives and changed how we communicate. Technology lets us live simply, more conveniently, and more easily, but at the same time, it creates complex debates and controversies of ethical problems. In this world, where humans cannot live without the benefits of technology, it is impossible to ignore ethical problems.
There was no such thing as worldwide web to provide instant access to information. Now internet is almost everywhere and changing our live. This research paper will focus on social engineering attacks taking place in the digital realm and addresses the following questions. What social engineering is?
CYBER CRIME Cybercrime is one of the fastest growing type of crime in our society today and have also been a serious problem since it causes a lot of damages and also affect us in different ways. But before I go further let me start by telling you the meaning of cybercrime, Cybercrime is different and more heinous than normal crime that we know. This crime is committed in an electronic medium and here means read is not a requirement and is done in secret Feldman(2013). Cyber war takes place largely in secret, unknown to the general public of crimes include pornography, cyber fraud, defamation, cyber stalking, harassment, IPR theft, data hostage, money laundering, phishing, e-mail bombing, cyber war, illegal monitoring. Secondly let me talk about the effect of cybercrime in our society today.
People from different sections of the universe are interacting, collaborating, socializing and doing other different activities via internet, which in turn exposes their personal information in cyberspace. Lack of knowledge and cyber security awareness makes these people to be vulnerable to hackers and other malicious players who use the cyber environment. These has been supported by Furnell, Bryan, Phippton, (2007) when they argued that personal or individual internet users are highly exposed to security threats while using their own home computers. It is therefore important that internet users should have clear understanding of all the risks of using internet, the importance of protecting their personal information and the outcome if this is not done
