1. What is the difference between a risk analysis (RA) and a business impact analysis (BIA)?
Any business uses resources, be it people, systems, money or information. These resources are all to a certain extent exposed to risks, and a risk analysis is supposed to give a comprehensive list of relevant risks.
The resources are used by the business however, so losing a resource has a business impact. A Business Impact Assessment analyses the effects of the loss of a resource and hence the risk.

2. What is the difference between a Disaster Recovery Plan and a Business Continuity Plan?
A Business Continuity Plan describes a set of procedures your company will use to continue critical business operations in the event of disruption (of those specific and/or all critical business operations). For instance, if the ability to take phone calls is a critical business operation (i.e. maybe you run a help desk), then you may define, in your BCP, what may cause a phone interruption, and what procedures you would take to respond to it.

Conversely, as stated by Massimo, the Disaster Recovery Plan (DRP) is a subset of your BCP. The DRP specifies the further reaching implications of disaster -- where your primary place (or all places) of business are uninhabitable. Not only is this relevant to your place of business, but your workforce as well (Workforce Continuity).

3. Typically, a business continuity plan is also a compilation or collection of other plans. What other plans might a BCP and all supporting documents include?
Disaster Recovery Plan (DRP), Incident Response Plan (IRP) and Business Impact Analysis (BIA)
Critical Business Functions (CBF).

4. What are the main difference between a Disaster recovery Plan (DRP) and a Business Continuity Plan (BCP)?
DRP list the recovery plan for systems and functions of a business. BCP usually will list every

Security on the Internet

... Security on the Internet The Internet has had security problems since its earliest days as a pure research project. Today, after several years and orders of magnitude of growth, is still has security problems. It is being used for a purpose for which it was never intended: commerce. It is somewhat ironic that the early Internet was design as a prototype for a high-availability command and control network that could resist outages resulting from enemy actions, yet it cannot resist college undergraduates. The problem is that the attackers are on, and make up apart of, the network they are attacking. Designing a system that is capable of resisting attack from within, is still growing and evolving at a fast pace, is probably impossible. Changes are needed, and once you have achieved a certain amount of size, the sheer inertia of the installed base may make it impossible to apply fixes. The challenges for the security industry are growing. With the electronic commerce spreading over the Internet, there are issues such as nonrepudiation to be solved. Financial institutions will have both technical concerns, such as the security of a credit card number or banking information, and legal concerns for holding individuals responsible for their actions such as their purchases or sales over the Internet. Issuance and management of encryption keys for millions of users will pose a new type of...

...Internet Security. Abstract Online users today are faced with multitude of problems and issues. A typical online user is vulnerable to virus, worms, bugs, Trojan horses etc.; he/she is also exposed to sniffers, spoofing their private sessions; and they are also vulnerable to phishing of financial information. Not only this but users are also constantly subjected to invasion of privacy with the multitude of spy ware available for monitoring their surfing behaviours. If this is not all, users are also subjected to malwares that stop or totally destroy their machines render them helpless. These instances only indicate that the Internet is not a safe place for online users. Users are constantly vulnerable to hacked sessions, attacks and phishes that make them wary of going online. However, the trend does not stop at that. In fact corporations and government sector organizations are also faced with the same problems. Corporate information are being hacked; emails are read; government secret information are subject to security risks and banks are being hacked and millions stolen. Some of the reasons behind such attacks include the weaknesses inherent in the networks of the companies and government organizations; other reasons include carelessness of users. Whichever the case internet security issues have become one of the major concerns for technologists and users alike. There is a great need for understanding the nature of the attacks, the attackers, the networks, the loop holes...

...need it. You and your family are at risk of virtual attacks. A decade ago, the Internet was something only “techies” talked about. It was a new limitless source of information, with very few users. Today, the Internet has already become an essential part of our lives. It’s where we access our banking records, credit card statements, tax returns and other highly sensitive personal information. By the end of this decade, over 2 billion people will be connected to the Internet—that’s about half the world’s current population. But with all the good things the Internet offers us, it also opens the door to serious, potentially devastating threats. Unlike corporate and government computer systems, few personal computers have any safeguards beyond basic virus protection. That means anytime you’re online, you are a potential target for online criminals and hackers. And if you have high-speed Internet access, your computer is online most of the time, making Internet criminals and hackers a 24-hour-a-day, year-round threat to you, your personal information, and your family. Understanding how the Internet works and the security threats you face. When you access the Internet, your computer sends a message over the Web that uniquely identifies your computer and where it is located. This allows the information you’ve requested to be returned to you. Often, this requested information carries with it unwanted hidden software created by hackers and online criminals. This...

...2. Internet security Internet Security, among different types of computer security, covers malware and hacking techniques. The Internet is an open zone where anyone can create a website that may place malware on your computer or server. This is also the space that gives shelter to people who are on the prowl to reach your computer or servers to access your data for misuse. You can divide the Internet into unknown and trusted sites. Trusted sites are simply the ones that you can trust, with a good example being your own office website. Obviously, you won't knowingly place any code on your own website to compromise the computer security of people visiting it. Another way to divide the Internet is into secure and non-secure zones. The secure zones are normally represented by a lock symbol in the address bar of your computer. An example of such sites can be your Internet banking site that employs high level encryption to secure their database as well as your computer. While you already know about malware, there are two more common techniques used by hackers to access your data: port knocking and packet sniffing. There are several ports on your computer that allow different applications to transfer data to and from your computer. A good application would instantly close the port as soon as it sends or receives information. However, there are some applications that delay or forget to close these ports. Sometimes it is the OS to blame. Port knocking, or port scanning, is the...

...Internet Censorship Name Institution Date Internet Censorship The number of internet users continues to increase daily and many of these users are young children. There are growing concerns regarding child censorship because the number of children accessing inappropriate adult sites is increasing. There is an urgent need to protect children online and ensure that they cannot access such sites, as well as protecting them from internet predators such as cyber bullies and paedophiles.One disturbing occurrence is that many children can now log into the internet from the privacy of their homes and gain access to all these sites. The internet has no regulations and is not governed by any body (Zuchora-Walske, 2010).Therefore that means that there are no checks as to the users of the internet, and this offers a risky proposition. Many people use the internet for retrieving beneficial information, but a large number also use the internet for things, which are detrimental and are inappropriate to the common population. Therefore, though child internet use is commendable, it should be carefully monitored to protect children from harmful elements. Children are often curious and are eager to discover new things on the internet, there is no limit to what children can discover, and this is dangerous. Censorship of the internet is therefore important because it ensures that there is safety as children navigate the internet. With censorship, children are able to access the internet without parental...

Security and Privacy on the Internet

...Security and Privacy on the Internet There are a lot of articles in the newspapers these days about databases hacked, personal information stolen, bank accounts “cleaned out”, or credit cards erroneously charged. When it comes to security and privacy on the Internet, how well does the system protect the public? Are certificate based security protocols as safe as one is lead to believe? Will modifying the Internet Explorer’s settings provide adequate privacy? As the “tech” world evolves and smart phones and other wireless devices become the norm, how secure are the Wi-Fi networks? Part of the problem is the technology is moving so fast, the rules cannot even keep up. Encryption is considered one of the better ways to help keep personal information secure, and give the user a “warm fuzzy” when the closed lock is displayed. Mr. Miguel Helft, New York Times, expresses a concern with the certificates issued by a third-party organization to guarantee a websites authenticity. According to the Electronic Frontier Foundation, more than 650 organizations can issue certificates used by Microsoft’s Internet Explorer and Mozilla’s Firefox for encryption. These organizations are located across the globe, like Russia and China which are suspected of internal public surveillance, and raise the question if the issuing organization is misusing certificates to eavesdrop on internet activity. Peter Eckersley, a senior staff technologist at the Electronic Frontier Foundation, tells of...

...Security Assessment of Ping Sweeps and Port Scans Antoine Rivers Devry University March 7, 2014 System security administrators will say that their network has been probed at some point or another. Hacking tools have become widespread and many in number and will likely continue to do so. Network probes are not infiltrations in themselves, however, they should not be overlooked because they can lead to real infiltrations. My essay will try to explain the two methods behind the most common network probes and how they can be prevented. The most prevalent form of attack is the port scan. A port scan is when potential infiltrators discover services currently in use on a network device. The infiltrator then strategizes an attack on one of the vulnerable services. For instance, if the infiltrator finds that port 143 (the IMAP port) is open, they may try to find out what version of IMAP is in use on the network device. If the version is vulnerable, they may be successful in gaining access to the device using an “expoit” or a program that exploits a hole in security. Port scans are easy to create. All a potential hacker has to do is connect to any port on the device and search which ports respond. Port scanners can easily be programmed in little time in one of the programming languages like Java. Nevertheless, port scans are easily found by operating systems of the vulnerable device. Since these types of scans are transparent, infiltrators are less likely to run this kind of port...

Internet Protocol Security

...MEANING OF INTERNET PROTOCOL SECURITY Internet Protocol Security is a framework of open standards for ensuring private secure connections over internet protocol (IP) networks through the use of cryptographic security services. It encrypts and authenticates each communication package on the network in a communication session. It can be used to protect communication between data hosts, security gate ways or security gateway and host. It has been deployed widely to implement virtual private networks. It supports two encryption modes, tunnel and transport. The transport mode encrypts only the data section of each packet while the tunnel mode encrypts both the header and the data section. On the receiving side, an Internet protocol security compliant device decrypts both the header and the data portion to present it to the user in a format he can understand. In the recent past there has been a lot of development in the information technology sector. Much if this development is based in information. It is therefore important to protect the information since it is not only precious and private, but if found in the wrong hands, it could be used to do a lot of damage for example terrorism. It has forced tech companies to develop secure ways of transmitting information without the interception of non-intended users. Information is a strategic resource. A significant portion of organizational budgets is spent on managing information. Hence information is a huge business where loads of...

Internet Security Today

...Daniel Kim 007781473 ENGR 350 Section 01 Current Event #1 The article begins by introducing Eugene Kaspersky, the “CEO of what is arguably the most important Internet security company in the world” (Shachtman). His company, Kaspersky Lab, protects over 50 million people today. However, Kaspersky Lab isn’t just an anti-virus company; it’s also a huge help in finding cyber-espionage. In 2010, one of Kaspersky’s researchers had found “Stuxnet”, a highly-sophisticated computer worm that targeted Siemens industrial software and equipment and became known as the world’s first cyber-weapon. Also, in May of 2012, Kaspersky Lab discovered “Flame”, another appearance of cyber-espionage aimed at Iran. Kaspersky’s prospect for the future of internet security is then mentioned, which includes “strictly monitored digital passports for some online activities and enabling government regulation of social networks to thwart protest movements” (Shachtman). He says that we are “too free”, that “freedom is good, but the bad guys can abuse this freedom to manipulate public opinion.” This is where people may agree or disagree with one another – whether to go with Kaspersky, an affiliate of the autocratic Putin regime who is also responsible for preserving the data of millions of people, or refuse and live with the risks of being allowed seemingly unrestricted freedom. The article continues on to describe the background and history of Kaspersky’s life, what goes on in his company, and...

Internet Privacy and Security

...Abstract Have you ever bought anything on the Internet with your credit or debit card? Do you think other people wouldn't like to buy things with your cards, too? Have you ever given out personal information to register for a contest or special event on the Web? If so, beware. In this paper, I will attempt to explore various privacy and security concerns facing both businesses and consumers when they take part in electronic commerce. Although the Internet offers a wonderful social, personal, and business opportunity, it is also laden with hackers, plotters, and schemers. This paper will examine some of the challenges posed by these shady individuals and look at measures Internet users can take to avoid becoming their victims. To survive in today’s highly competitive business environment, successful E-businesses must market their products and services to individuals or other businesses that are “willing and able” to purchase their offerings. To assist them in identifying and targeting specific market segments, companies are now using data mining techniques to examine their databases looking for trends, relationships, and outcomes to enhance their overall operations. These databases, containing detailed consumer information, can be valuable resources for the companies that use them. They can help businesses to better understand the needs of their customers so they can react to the customer’s needs faster. Businesses can also utilize this information to cut production...

Many major corporations use social networking and the Internet to market and sell products, which requires the collection of data in order to facilitate these purchases. Unfortunately this can leave these corporations vulnerable to security breaches in an attempt to steal the information contained in these databases. One major corporation that suffered a security breach recently was Sony Corporation, which had two database security breaches in 2011. Sony Corporation was founded in May of 1946 and is headquartered in Tokyo, Japan with a U.S. Division called Sony Corporation of America. They have approximately 168,000 employees worldwide. Their major product lines are audio, video, televisions, information and communications, semiconductors, and electronic components. In 2010 global consolidated sales and operating revenue were $7,181,300 billion Yen or approximately $89.8 million US dollars (Sony Corporation, 2012).

...Assignment 4: Internet Technology, Marketing, and Security Bus 508 – Contemporary Business Abstract Modern business depends on complex electronic information systems that require computer and internet capability to keep that information flowing. There is a problem when someone outside of that business relationship between the business and the consumer interferes, or hacks, that information flow. An entire industry has been created to protect that information flow from being “hacked”. In 2011, Sony went through what is known as the largest security breach in history. The breach affected 77 million PlayStation Network users, 24.5 million users of Sony Online Entertainment and many more customers across the nation. All this was caused, according to Sony, by an “outdated database from 2007” (Lina, 2011). Assignment 4: Internet Technology, Marketing, and Security In 2011, there were more than 300 corporate security breaches. Sony, Citigroup, and Morgan Stanley Smith Barney are among the major firms that have reported to their customers that they have been hacked (Mintzer, 2011). Hacking is continuously happening to companies all over the world.
