Hack IT Security Through Penetration Testing pdf

Breaking into systems can be relatively simple if someone has not properly patched and secured the systems against the latest vulnerabilities. Keeping systems up to date has become increasingly difficult with larger multi-OS distributed networks and smaller staff budgets. The issue facing administrators trying to keep systems up to date is that 20–70 new vulnerabilities are published each month on Bugtraq, eSecurityonline, and other vulnerability services. Unfortunately, hackers have a window of opportunity between the time someone publishes the vulnerability and the time the vulnerability is patched or addressed on the systems. The longer this window stays open, the more the odds of compromise increase. One of the keys to keeping your network secure is to constantly monitor for emerging vulnerabilities and to patch your systems against them. The more responsive administrators are to closing the holes, the more secure your systems will be. Configuration errors create a risk that enables attackers to penetrate systems. Examples of configuration errors include leaving unnecessary services open, assigning incorrect file permission, and using poor controls for passwords and other settings that a system administrator can set. Organizations can reduce configuration errors by creating baseline standards and configuration management procedures. In addition, proper penetration testing will identify many configuration holes that could allow an attacker to gain access to systems.

The Ethical Hack A Framework for Business Value Penetration Testing pdf

Rich O’Hanley, my editor from Auerbach Publications, was instrumental in helping get this book completed. His trust in me was a constant driver to ensure a valuable project. Anton Chuvakin, Ph.D. was one of the first to review the book in its entirety. His comments were not only inspiring, but provided a great deal of insight to making the book better. Steve Coman, an unwitting influence and a long- time friend, appears in many places in this book. Endless conversations about security on a boat, in a bar, and over the phone or dinner have provided me everlasting impressions of security. Steve always questioned security and the perceptions of it in the business world and from the trenches. Ed Skoudis, the author of Counter Hack: A Step-by-Step Guide to Computer Attacks and Effective Defenses not only wrote the foreword, but was incredibly helpful in making sure I was on the right track. Many thanks to Ed for taking the time to review the material and always providing support for the book. Jay Heiser, another unwitting accomplice, author of Computer Forensics: Incident Response Essentials, and a friend and former col- league, provided many perspectives of security that will stay with me forever. Many e-mails and conversations (aka arguments) about security helped to formulate some of my perspectives. You can catch some of his writings in Information Security magazine. Wayne Selk provided a great deal of assistance throughout the book. He is an old friend from way back and our discussions about security have certainly appeared here. Wayne has been a UNIX expert for years, overseeing large service provider networks, and is a security consultant for Symantec.

Would you walk into a dark alley on the secluded part of the street at night, wearing expensive jewelry? You wouldn't. Similarly, be wary of dubious websites that parade as reputed ones. Also avoid visiting porn sites, gaming websites and sites promising free music and movie downloads. These websites are frequently tracked by hackers and anything you view or download from these sites may contain malware that may harm your computer and compromise its security.

In the next section, I wanted to give you an example of how you can take banner data and quickly search through all your scan results. I created a MongoDB backend database (for speed purposes) and used PHP as the frontend. To push data to the DB, a quick python script was created to parse the XML file from Nmap. I then created a PHP page to query this data. Since I was scanning numerous/16 networks, I needed a quick way to identify unique banner pages that might be of interest to me. Ideally, if I have time I’ll have a publicly assessable version of this application where you can upload your own xml file and see the results.

Probably the most obvious role to assign to hackers, and the one that the media would most like to paint them with, is that of criminal.This is “obvious” only because the vast majority of the public outside of the information security industry thinks this is what “hacker” means. Make no mistakes, there are hackers who commit crimes.The news is full of them. In fact, that’s probably the reason why the public perception of what a hacker is has become so skewed, virtually all hacker news stories have to do with crimes being committed. Unfortunately, most news agencies just don’t consider a hacker auditing a codebase for overflows and publishing his results to be front-page news. Even when something major happens with hackers unrelated to a crime, such as hackers advising Congress or the President of the United States of America, it gets relatively limited coverage. Do the criminal hackers server any positive purpose in society? That depends on your point of view. It’s the same question as “do criminals server any positive purpose?”

Hack Proofing Your Network pdf

Snake oil? What does that have to do with a chapter on cryptography? Snake oil is a term that was used in the 1800s to describe quack medicine, such as the cure-all elixirs sold at traveling medicine shows. In regards to cryptog- raphy, it describes untrustworthy cryptography products. Just because a product uses a well-known algorithm such as blowfish does not mean that the implementation of the algorithm guarantees a good security product. Caveat emptor! Also beware of outrageous product claims, such as “our product uses a key length of 12288, so it will never be broken,” as this is as misleading as the cure-all elixir claims of yesteryear. One of the biggest signs to watch out for is for any cryptography product that claims to use a propri- etary algorithm. They make it seem as though they are “protecting” the algo- rithm from the bad guys and thus it will never be broken. If you run into this type of cryptography vendor, then run in the opposite direction as fast as you can! Any respectable cryptographers will gladly release their algorithm(s) to public scrutiny—unless they intentionally have something to hide, that is. Keep this in mind when you are looking to implement cryptography in your business processes.

Analysis of Various tools of Penetration Testing Harshdeep Singh 1, Jaswinder Singh2

Water, Network penetration testing is a technique of finding out vulnerabilities related to security threats for organizations and companies in their network security before any hacker can break into their system [9]. A number of different penetration tests are performed on the security network to ensure the safety of the system to the hacking of any confidential and important data such as funds, consignment details, etc. The aim of network penetration is to simulate the hacking attack or cyber-attack and thus to discover the areas of weakness in the security network system. The results enable the user to work on security problems to set the network security levels which cannot get hacked by understanding and overcome the vulnerabilities to the system. The technique provides the user with the vulnerabilities which can be found by the hacker and helps in counterattacking the chances of being hacked. [14] Network Penetration

Xbox hack pdf

Xbox hack pdf

It has recently been called to the author’s attention that the hardware initialization pro- cedure of the Xbox contains a significant weakness. [17] Recall from section 2 that the first step in the Xbox boot process is to load the “jam tables” that configure the console’s chipsets. This jam table initialization procedure involves a lengthy and com- plex sequence of writes to various memory-mapped hardware register locations. As a result, the initialization procedure is implemented using a simple bytecode interpreter that reads initialization commands and data from the FLASH ROM. These bytecode commands–stored as plaintext–can be manipulated to cause the initialization procedure to abort before the kernel decryption/verification routine is executed, and to instead run insecure code directly out of the FLASH ROM. In other words, with plaintext-only modifications in the FLASH ROM, one can entirely bypass the Xbox’s security mech- anism. One could easily fix this security hole, however, by verifying the jam table’s contents prior to bytecode execution with a one-way hash function, or by explicitly coding all initialization functions within the secure boot block. Both of these solutions, however, would require the secure boot block to grow significantly from its current 512-byte size, and neither solution allows easy changes to the initialization procedure in case a bug is found or in case the hardware evolves as a result of cost reduction efforts.

Credit Card Visa Hack pdf

Credit Card Visa Hack pdf

The customer PIN is the primary security measure against fraud; forgery of the mag- netic stripe on cards is trivial in comparison to PIN acquisition. A street criminal can easily steal a cash card, but unless he observes the customer enter the PIN at an ATM, he can only have three guesses to match against a possible 10,000 PINs and would rarely strike it lucky. Even when successful, his theft still cannot exceed the daily withdrawal limit of around £300 . However, bank programmers have access to the computer systems tasked with the secure storage of PINs, which normally consist of a mainframe connected to a “Hardware Security Module” (HSM) which is tamper-resistant and has a restricted API such that it will only respond to with a YES/NO answer to a customer’s guess.

Web Security Testing Cookbook pdf

Web Security Testing Cookbook pdf

One of the more difficult aspects of testing system-level attributes such as security is the sheer inability to exhaustively complete the task. In the case of security, we provide evidence about the lack of vulnerabilities. Just as you cannot prove the non-existence of bugs, exhaustive security testing is both theoretically and practically impossible. One advantage you have over an attacker is that you don’t have to fully exploit a defect in order to demonstrate its existence and fix it. Often just observing a potential vul- nerability is enough to prompt a fix. Spotting the warning signs is the first step towards securing an application. If your tests do not reveal signs of trouble, you are that much more confident in your software’s security. So while many of these recipes may seem simplistic, they form a basis for noticing warning signs, if not actual vulnerabilities. Fixing the application’s behavior is more effective than simply preventing pre-canned attacks. For instance, many penetration testers will cause a standard alert box to show up on a web page and declare a job well done—the website can be hacked! This causes confusion among developers and product managers. They ask: who cares about a stu- pid pop-up alert box? The answer is that the alert box is just a hint—a warning sign that a website is vulnerable to cross-site scripting (something we’ll discuss in more detail in later recipes, such as Recipe 12.1 on stealing cookies via XSS). It is possible to build the observations from this chapter into full, working exploits. In fact, Chap- ter 12 shows several ways to do just that. Exploits are time-consuming, though, and they consume time that could be used to build more and better tests for different issues. For now, we focus on spotting the the first signs of vulnerability.

163 The Basics Of Hacking And Penetration Testing [ PUNISHER ] pdf

when not spending time with my family, there are two things i enjoy doing: reading and hacking. most of the time, i combine these hobbies by reading about hacking. As a professor and a penetration tester, you can imagine that my bookshelf is lined with many books on hacking, security, and penetration test- ing. As with most things in life, the quality and value of every book is different. some books are excellent resources that have been used so many times that the bindings are literally falling apart. others are less helpful and remain in nearly new condition. A book that does a good job of explaining the details without losing the reader is worth its weight in gold. Unfortunately, most of my per- sonal favorites, those that are worn and tattered, are either very lengthy (500 pages) or very focused (an in-depth guide to a single topic). neither of these is a bad thing; in fact, quite the opposite, it is the level of detail and the clarity of the authors’ explanation that make them so great. But at the same time, a very large tome focused on a detailed subject of security can seem overwhelming to newcomers.

An extensive set of effective policies — one that employs full and accurate analysis to provide the right response for any given event — is the foundation of any DLP solution. While it is critical to be able to quickly and easily create and deploy policies, it is just as important that the policies you employ effectively capture your company‘s best practices and business rules. Your DLP solution should draw on a complete set of customizable, prebuilt, and tested policies that can address an array of security and compliance issues or target a particular area of risk with pinpoint precision. Most must be 100% ready for immediate deployment across all critical risk points, including e-mail, Web, and Instant Messaging. Some may require customer specific configuration to ensure optimum operation in a particular environment. With either approach, the time and effort required to design,

the frame level and the RF level. The proposed solution incorporates AES encryption, in conjunction with 802.1x authentication Free RADIUS server, provides a required frame security level for WLANs. It achieves the standard security requirements because AES offers the standard confidentiality and integrity and free RADIUS server offers the required authentication, access control, and non-repudiation. To achieve the full availability, the RF security level must be achieved. Detecting and preventing attackers are the best solution to achieve the RF security level. WIDS software detects the rogue access points and illegal hotspots. There are many kinds of WIDS software as kismet, airdrop and snort IDS. Also, WDS protects the network from hacking, whether intended or not intended as viruses and Trojans. Granting different privileges to the users in VLANs, isolating VLANs help with ease putting security policies and control users.

Metasploit Toolkit for Penetration Testing, Exploit Development, & Vulnerability Research pdf

For those of us who were fortunate enough to attend Blackhat Las Vegas 2004, the scene in hall {##} was unforgettable.The title of the talk was “Hacking Like in the Movies.” HD Moore and spoonm were on stage presenting the arrival of their tool Metasploit Framework (MSF) version 2.2.The hall was packed to the gills. People stood in the aisles, and the crowd was spilling over to the main corridor.Two screens glowed to life—the black one on the left showing the MSF commands in action, and the blue one on the right showing a Windows system being compromised. Applause flowed freely throughout the session, and the con- sensus was clear, “Metasploit had come of age.” But we should have known better.That was only a taste of things to come. With the arrival of MSF version 3.0, the entire approach to information security testing is likely to be revolutionalized. MSF 3.0 is not only an exploit platform, but it is in fact a security tool development platform.The application program interfaces (APIs), architecture, and indeed the philosophy behind the tool promise to make its launch one of the most exciting events in recent times.

Server Message Block (SMB) is a file sharing protocol that allows computers to share information transparently across the network. The “Windows credentials” drop-down menu item has settings to provide Nessus with information such as SMB account name, password and domain name. Providing this information to Nessus will allow it to find local information from a remote Windows host. For example, using credentials enables Nessus to determine if important security patches have been applied. Only expert security personnel should modify other SMB parameters from default settings.

Even experienced wireless security analysts can benefit from the content in this book. For example, many organizations are deploying wireless cameras to improve physical security (while destroying any shred of wireless security in the process). More than just searching for the ever-elusive shower cam (personally, I don’t want to see what goes in on people’s showers), attackers are looking to discover and exploit these unprotected video feeds. I met one researcher who summed up the problems of wireless cameras nicely for me when referring to a wireless camera in a bank: “… if someone wanted to rob the place, all they would need to do is override the signal, and they would never be caught on tape.” Identifying and assessing the exposure of these wireless cameras should be part of any wireless audit or vulnerability assessment (Chapter 11).
