The materiel! Thanks to Heather for all your hard work and keeping me on task. Every author should be so fortunate to have you helping them.
And Ei very special thanks to Jennifer. FN always appreciate and love you more than words can express. Thanks for being the Zelda to my Link,. Throughout his career, he hits held positions such as support specialist to consultants and senior instructor, Currently, he is an IT instructor who specializes in infrastructure and security topics for various public and private entities.
Oriyano has instructed for the 11 S. Air Force. Navy, and Army at locations both in North America and internationally. He is a cybersecurity expert focused on IT networks and security assessments. His written works in J he iield of IT security include authoring or coauthoring 14 security books.
They also initiated many early software-development movements that led to what is known today as open source. In the s, hackers started gaining more of the negative connotations by which the public now identifies them.
In many respects, the s formed the basis for what a hacker is today. Over the past two decades, the definition of what a hacker is has evolved dramatically from what was accepted in the s and even the s.
Current hackers defy easy classification and require categorization into several groups to better match their respective goals. Here is a brief look at each of the groups to better understand what the information technology industry is dealing with:.
White-hat hackers — These individuals know how hacking works and the danger it poses, but use their skills for good. For obvious reasons, not all people will trust a gray-hat hacker. Black-hat hackers — A black-hat hacker has, through actions or stated intent, indicated that his or her hacking is designed to break the law r disrupt systems or businesses, or generate an illegal financial return.
They may have an agenda or no agenda at alL In most cases, black-hat hackers and outright criminal activity are not too far removed from one another. The purpose of this book is to teach you how to ensure the security of computers and networks by learning and understanding the mindset of individuals out to compromise those systems.
To defend information technology assets, you need to understand the motivations, tools, and techniques that attackers commonly use,. Origan mi Lams of till sizes hiwc Jeanied to reduce threats through a combination of technological, ad in in is t rati ve h and physical measures designed to address a specific range of problems. Technological measures include devices and techniques such as virtual private networks l VPN si. Administrative controls include.
However, there are many experienced hackers who never break the law r and who define hacking as producing an outcome the system designer never anticipated. No offense is intended to either group.
Physical measures include devices such as cable locks, dei r ice locks, alarm systems, and other similar devices. Keep in mind that each of these devices, even if expensive, can be cheaper and more effective than cleaning up the aftermath of an intrusion.
While discussing attacks and attackers, security professionals must be thorough in assessment and evaluation of the threat by also considering where it comes from. When evaluating the threats against an organization and possible sources of attack, always consider the fact that attackers can come from both outside and inside the organization.
A single disgruntled employee can cause tremendous amounts of damage because he or she is an approved user of the system. In just about any given situalion, Lhe attacks originating fro in fiutsuii 1 the firewall will greatly outnumber the attacks that originate from the inside. However, an insider may go unnoticed longer and also have some level of knowledge of how things work ahead of time, which can result in a more effective attack. Because the risk to any organization is very real, it is up to each organization to determine the controls that will be most effective in reducing or mitigating the threats it faces.
When considering controls, you can examine something called the TAP principle of controls, TAP is an acronym for technical, adminis- trative, and physical! Administrative — Administrative controls take the form of policies and procedures. An example is a password policy that defines what makes a good password. In numerous cases, administrative controls may also fulfill legal requirements, such as policies that dictate privacy of customer information. Other examples of administrative policy include the rules governing the hiring and firing of employees.
Physical — Physical controls are those that protect assets from traditional threats such as theft or vandalism. Mechanisms in this category include locks, cameras, guards, lighting, fences, gates, and other similar devices,. Both insiders and outsiders rely on exploits of some type. Remember that an exploit refers to a piece of software, a toolj or a technique that targets or takes advantage of a vulnerability — leading to privilege escalation, toss of integrity, or denial of service on a computer system.
Like many criminals, black -hat hackers do not consider their activities to be illegal or even morally wrong. Depending on whom you ask, you can get a wide range of responses from hackers on how they view [heir actions. It Ik also not unhenrd of for hackers or criminals to have a code of ethics that they hold sacred, but seem more than a little.
In defense of their actions, hackers have been known to cite all sorts of reasons, including the following:. Although it is true that applications or data can be erased or modified, worse scenarios can happen under the right circumstances. For example, consider what could happen if someone broke into a system such as a emergency service and then maliciously or accidentally took it down.
The computer game fallacy — If the computer or system did not take any action or have any mechanism to stop the attack, it must be OK. The shatterproof fallacy — Computers cannot do any real harm. The worst that can happen is a deleted file or erased program. The hacker fallacy — Information should be free. No one should have to pay for books or media. Everyone should have free access. Another example of attempting to explain the ethics applied to hackers is known as the hacker ethic.
This set of standards dates to Steven Levy in the s, In the preface of his book, Hackers: Heroes of the Computer Revolution, Levy stated the following:. One must also consider motivation. Anyone who has watched ei police drain a or is a fan of detective stones knows that there are three things needed to commit a crime:.
Focusing on the second point — motive — helps better understand why an attacker might engage in hacking activities. Revenge or grudge — Attacks conceived and carried out by individuals who are angry at an organization. Attacks of this nature Eire often launched by disgruntled employees or customers,.
Hacktivism — Attacks that are carried out to bring attention to a cause, group, or political ideology. These attacks can he indiscriminate in their execution. Tor example, attackers may htiek a game server to boost their stats in an online game against their friends, but they still have entered a server without authorization,.
A relatively new form of hacking is the idea of hacking in behalf of a cause. In the past r hacking was done for a range of different reasons that rarely included social expression. Over the past decade, however, there have been an increasing number of security incidents with roots in social or political activism.
Examples include defacing Web sites of public officials, candidates, or agencies that an individual or group disagrees with, or performing DoS attacks against corporate Web sites. A sampling of common attacks that lit the definition of computer crime include the following:. Theft of access — Stealing, pels swords, stealing usernames, and subverting access mechanisms to bypass normal authentication.
In a number of situations, the very act of possessing stolen credentials such as passwords may be enough to bring formal charges. Network intrusions — Accessing a system of computers without authorization. Intrusions may not even involve hacking tools; the very act of logging into a guest account may be sufficient to be considered an intrusion. Emanation eavesdropping — Smiling devices for intercepting radio frequency IRF signals gen untied by computers or terminals.

Но Пьер Клушар провалился в глубокое забытье. ГЛАВА 23 Сьюзан, сидя в одиночестве в уютном помещении Третьего узла, пила травяной чай с лимоном и ждала результатов запуска Следопыта. Как старшему криптографу ей полагался терминал с самым лучшим обзором. Он был установлен на задней стороне компьютерного кольца и обращен в сторону шифровалки. Со своего места Сьюзан могла видеть всю комнату, а также сквозь стекло одностороннего обзора ТРАНСТЕКСТ, возвышавшийся в самом центре шифровалки. Сьюзан посмотрела на часы. Она ждет уже целый час.
Ясно, что без объяснений ему не обойтись. Она это заслужила, подумал он и принял решение: Сьюзан придется его выслушать. Он надеялся, что не совершает ошибку. - Сьюзан, - начал он, - этого не должно было случиться. - Он провел рукой по своим коротко стриженным волосам. - Я кое о чем тебе не рассказал.
Коммандер. Нужно выключить ТРАНСТЕКСТ. У нас… - Он нас сделал, - сказал Стратмор, не поднимая головы.
Джабба глубоко вздохнул и понизил голос. - Вирусы, - сказал он, вытирая рукой пот со лба, - имеют привычку размножаться. Клонировать самих. Они глупы и тщеславны, это двоичные самовлюбленные существа. Они плодятся быстрее кроликов.
Мужчина рядом нахмурился. - Turista, - усмехнулся. И прошептал чуть насмешливо: - Llamo un medico. Вызвать доктора. Беккер поднял глаза на усыпанное родинками старческое лицо.
