Contents at a Glance Preface A solid grasp of the objectives, terminology, principles, and frameworks will help them understand how to place issues in a proper context for determining working solutions.
That is the goal of this text: to introduce students to the most important topics of information security and pique their interest to learn more.
The body of knowledge as it is called in the IT security industry is vast, deep, and, principles of information security 6th edition pdf download times, baffling. Solutions are not always straightforward because the problems they address are rarely intuitive.
No cookbook or universal recipe for IT security success exists. Ideally, protecting computer systems from attacks and unauthorized access means anticipating problems and devising strategies to address how people, processes, and technologies interact. The goal, although not always realistic, is to prevent these problems from happening instead of simply reacting to them as so many organiza- tions do today. This is rarely easy. This book navigates the ocean of information technology IT security issues while keeping the technical jargon to a minimum.

Jim Breithaupt is a data integrity manager for a major bank, where he manages risk for a large data mart.
He has more than 30 years of data processing experience and has co-authored several other books on information systems and information security, along with Mark Merkow. Without Jim, there would be no book. Thanks to my wife, principles of information security 6th edition pdf download, Amy Merkow, as always, for her positive attitude, full support, and unwavering belief in the written word. I also want to thank our far-scattered children, Josh Merkow, Jasmine Merkow, Brandon Bohlman, and Caitlyn Bohlman, for their support throughout the writing process.

For example, new programming and systems analysis and design skills can often be applied on new systems-development projects as companies espouse principles of information security 6th edition pdf download computing and mobile infrastructures that access internal systems.
Although their technical skills are certainly important, the best security specialists combine their practical knowledge of computers and networks with general theories about security, technology, and human nature. These concepts, some borrowed from other fields, such as military defense, often take years of sometimes painful professional experience to learn. With a conceptual and principled view of information security, you can analyze a security need in the right frame of reference or context so you can balance the needs of permitting access against the risk of allowing such access.
No two systems or situations are identical, and no cookbooks can specify how to solve certain security problems. Instead, you must rely on principle-based analysis and decision making. Yet in late Aprilthieves broke into the museum, evaded the layered security system, and made off with the three masterpieces. This principle applies to the physical world as well and is best illustrated with an analogy of safes or vaults that businesses commonly use to protect their assets.
Safes are rated according to their resistance to attacks using a scale that describes how long it could take a burglar to open them. They are divided into categories based on the level of protection they can deliver and the testing they undergo.
This rating describes the thick- ness of the steel used principles of information security 6th edition pdf download make the lockbox. No actual testing is performed to gain this rating. Q C-Rate: This is defined as a variably thick steel box with a 1-inch-thick door and a lock, principles of information security 6th edition pdf download.
No tests are conducted to provide this rating, either. The UL TL label requires that the safe be constructed of 1-inch solid steel or equivalent.
Engineers exercise more than 50 different types of attacks that have proven effective for safecracking. Testers get 30 minutes and a few more tools to help them gain access. FYI: Confidentiality by Another Name Confidentiality is sometimes referred to as the principle of least privilege, meaning that users should be given only enough privilege to perform their duties, principles of information security 6th edition pdf download, and no more.
Some other synonyms for confidentiality you might encounter include privacy, secrecy, and discretion. The outcomes of principles of information security 6th edition pdf download testing are the same, though: As with software, no safe is burglar proof; security measures simply buy time. Of course, buying time is a powerful tool. Resisting attacks long enough provides the opportunity to catch the attacker in the act and to quickly recover from the incident. This leads to the second principle.
FYI: Confidentiality Models Confidentiality models are primarily intended to ensure that no unauthorized access to information is permitted and that accidental disclosure of sensitive information is not possible. Common confidentiality controls are user IDs and passwords. Principle 2: The Three Security Goals Are Confidentiality, Integrity, and Availability All information security measures try to address at least one of three goals: Q Protect the confidentiality of data Q Preserve the integrity of data Q Promote the availability of data for authorized use These goals form the confidentiality, integrity, availability CIA triad, the basis of all security programs see Figure 2.
Information security professionals who create policies and procedures often referred to as governance models must consider each goal when creating a plan to protect a computer system. FYI: CIA Triad The principle of information security protection of confidentiality, integrity, and availability cannot be overemphasized: This is central to all studies and practices in IS.
Integrity Models Integrity models keep data pure and trustworthy by protecting system data from intentional or acci- dental changes. Integrity models have three goals: Q Prevent unauthorized users from making modifications to data or programs Q Prevent authorized users from making improper or unauthorized modifications Q Maintain internal and external consistency of data and programs An example of integrity checks is balancing a batch of transactions to make sure that all the infor- mation is present and accurately accounted for.
Availability Models Availability models keep data and resources available for authorized use, especially during emer- gencies or disasters. Principle 3: Defense in Depth as Strategy A bank would never leave its assets inside an unguarded safe alone.
Typically, access to the safe requires passing through layers of protection that might include human guards and locked doors with special access controls. Furthermore, the room where the safe resides could be monitored by closed- circuit television, motion sensors, and alarm systems that can quickly detect unusual activity. The sound of an alarm might trigger the doors to automatically lock, the police to be notified, or the room to fill with tear gas.
Layered security, as in the previous example, is known as defense in depth. This security is imple- mented in overlapping layers that provide the three elements needed to secure assets: prevention, detection, and response. Defense in depth also seeks to offset the weaknesses of one security layer by the strengths of two or more layers.
In the information security world, defense in depth requires layering security devices in a series that protects, detects, and responds to attacks on systems. For example, a typical Internet-attached network designed with security in mind includes routers, firewalls, and intrusion detection systems IDS to protect the network from would-be intruders; employs traffic analyzers and real-time human monitors who watch for anomalies as the network is being used to detect any breach in the layers of protection; and relies on automated mechanisms to turn off access or remove the system from the network in response to the detection of an intruder.
Finally, the security of each of these mechanisms must be thoroughly tested before deployment to ensure that the integrated system is suitable for normal operations. After all, a chain is only as good as its weakest link. Principle 3: Defense in Depth as Strategy 23 In Practice Phishing for Dollars Phishing is another good example of how easily intelligent people can be duped into breaching security.
Phishing is a dangerous Internet scam, and is becoming increasingly dangerous as targets are selected using data available from social media and enable a malicious person to build a profile of the target to better convince him the scam is real.
A phishing scam typically operates as follows: Q The victim receives an official-looking email message purporting to come from a trusted source, such as an online banking site, PayPal, eBay, or other service where money is exchanged, moved, or managed. Q The email tells the user that his or her account needs updating immediately or will be suspended within a certain number of days.
Q The email contains a URL link and instructs the user to click on the link to access the account and update the information. The link text appears as though it will take the user to the expected site. Q At the spoofed site, the user enters his or her credentials ID and password and clicks Submit.
Phishing and resultant ID theft and monetary losses are on the increase and will begin to slow only after the cycle is broken through awareness and education.
Q Do not click on links embedded in unsolicited finance-related email messages. A link might look legitimate, but when you click on it, you could be redirected to the site of a phisher. Q Check with your provider for messages related to phishing scams that the company is aware of, principles of information security 6th edition pdf download.
Three-quarters of respondents revealed the information immediately, and an additional 15 percent did so after some gentle probing. Study after study like this one shows how little it takes to convince someone to give up their credentials in exchange for trivial or worthless goods.
