SQL Injection Attacks by Example A customer asked that we check out his intranet site, which was used by the company's employees and customers. This was part of a larger security review, and though we'd not actually used SQL injection to penetrate a network before, we were pretty familiar with the general concepts. We were completely successful in this engagement, and wanted to recount the steps taken as an illustration. "SQL Injection" is subset of the an unverified/unsanitized user input vulnerability ("buffer overflows" are a different subset), and the idea is to convince the application to run SQL code that was not intended. Decorators with Zend_Form Zend_Form has been lauded by many as a welcome addition to Zend Framework, and a flexible solution to the problem of forms. That said, one point of flexibility it offers has proved to be a pain point for many developers: decorators. This tutorial aims to shed some light on decorators, as well as provide strategies for creating your own decorators and combining them in creative ways to customize the output your forms generate. Background When designing Zend_Form, a primary goal was that it should generate the markup necessary to display each element and the form itself. The rationale was that injecting values and metadata into the element markup and reporting errors is often a tedious, repetitive task.
Kohana: The Swift PHP Framework Kohana is a PHP 5 framework that uses the Model View Controller (MVC) architectural pattern. There are several reasons why you should choose Kohana but the main ones are security, weightlessness and simplicity. In this tutorial, I'll introduce its main features, and, with a simple demonstration, I'll show you how much time Kohana can potentially save you. Bastion host Background ...a system identified by the firewall administrator as a critical strong point in the network's security. Generally, bastion hosts will have some degree of extra attention paid to their security, may undergo regular audits, and may have modified software. Definition It is a system identified by firewall administrator as critical strong point in network security.

HTTP/1.1: Status Code Definitions Each Status-Code is described below, including a description of which method(s) it can follow and any metainformation required in the response. 10.1 Informational 1xx This class of status code indicates a provisional response, consisting only of the Status-Line and optional headers, and is terminated by an empty line. There are no required headers for this class of status code. Since HTTP/1.0 did not define any 1xx status codes, servers MUST NOT send a 1xx response to an HTTP/1.0 client except under experimental conditions. A client MUST be prepared to accept one or more 1xx status responses prior to a regular response, even if the client does not expect a 100 (Continue) status message.
Security Auditing Updated: January 25, 2010 Applies To: Windows Server 2008, Windows Server 2008 R2 This navigation topic for the IT professional describes the documentation available to plan, implement, and monitor events by using features found in Windows Security Auditing. Security auditing is one of the most powerful tools that you can use to maintain the security of your system. As part of your overall security strategy, you should determine the level of auditing that is appropriate for your environment. Auditing should identify attacks (successful or not) that pose a threat to your network, and attacks against resources that you have determined to be valuable in your risk assessment.
Intrusion detection system An intrusion detection system (IDS) is a device or software application that monitors network or system activities for malicious activities or policy violations and produces reports to a management station. IDS come in a variety of “flavors” and approach the goal of detecting suspicious traffic in different ways. There are network based (NIDS) and host based (HIDS) intrusion detection systems. Some systems may attempt to stop an intrusion attempt but this is neither required nor expected of a monitoring system.
Revocation list In the operation of some cryptosystems, usually public key infrastructures (PKIs), a certificate revocation list (CRL) is a list of certificates (or more specifically, a list of serial numbers for certificates) that have been revoked, and therefore, entities presenting those (revoked) certificates should no longer be trusted. Revocation states There are two different states of revocation defined in RFC 3280: Revoked: A certificate is irreversibly revoked if, for example, it is discovered that the certificate authority (CA) had improperly issued a certificate, or if a private-key is thought to have been compromised. Certificates may also be revoked for failure of the identified entity to adhere to policy requirements, such as publication of false documents, mis-representation of software behavior, or violation of any other policy specified by the CA operator or its customer. Reasons for revocation
SSL/TLS Strong Encryption: How-To The solution to this problem is trivial and is left as an exercise for the reader. -- Standard textbook cookie How to solve particular security problems for an SSL-aware webserver is not always obvious because of the interactions between SSL, HTTP and Apache's way of processing requests. This chapter gives instructions on how to solve some typical situations. Treat it as a first step to find out the final solution, but always try to understand the stuff before you use it. Nothing is worse than using a security solution without knowing its restrictions and how it interacts with other systems.
