Network Security Auditing Tools and Techniques Evaluating Security Controls. Assessing security controls involves more than simply scanning a firewall to see what ports are open and then running off to a quiet room to generate a report. It is natural for security engineers to gravitate toward technology and focus on technical security control testing otherwise known as penetration testing, because it is likely the fun part of security for most engineers. Conducting a penetration test is like throwing down the gauntlet to security professionals, and it gives them an opportunity to flex their hacker skills.

One thing is certain about security auditing tools The power and sophistication of tools that auditors have at their disposal increase. Testing security as a system, however, involves significantly more than launching carefully crafted evil packets at the network to see what happens. This chapter discusses software tools and techniques auditors can use to test network security controls. It is important to note that this is not a chapter about hacking. You will not learn all of the techniques and tools available today for breaking into networks.

Security testing as a process is covered, but the focus is on gathering the evidence useful for an audit. Thoroughly assessing security controls serves a vital part in determining whether or not a business is compliant with its policies, procedures, and standards. Through security controls testing, you can determine whether the organization meets its goals for reducing risk and keeping evildoers out of the network and away from critical systems.

Security controls are the safeguards that a business uses to reduce risk and protect assets. Policy determines what security controls are needed, and those controls are selected by identifying a risk and choosing the appropriate countermeasure that reduces the impact of an undesirable event such as a customer database being stolen. The evaluation of security controls in its simplest form validates whether or not the control adequately addresses policy, best practice, and law. Testing security controls for effectiveness and measuring them against standards are of the best ways to help an organization meet its obligations to shareholders and regulatory responsibilities. As discussed in Chapter 1, The Principles of Auditing, the main security control types are administrative, technical, and physical. Under each category, the specific controls that can be implemented are preventative, detective, corrective, or recovery. These control types work together, and in general, you must provide controls from each category to effectively protect an asset. When testing controls, make sure that each functional category is addressed and all controls are implemented in a way that doesnt allow someone easy circumvention. You can have the most advanced firewall in the world as a preventative control, but without monitoring its effectiveness through detective controls, such as log reviews and IPS, you would never know for sure if it enforced policy. These missing pieces are typically what hackers exploit to break into systems, and its the auditors job to identify and report on weaknesses in the system. When evaluating security effectiveness, you need to examine three primary facets for every control. All security incidents, from break ins to lost customer records, can usually be traced back to a deficiency that can be attributed to people, process, or technology. Testing these areas enables you to analyze security from a big picture perspective, gives you a better understanding of how an organization performs today, and recommends improvements for tomorrow. Following are the three facets to examine People are users, administrators, data owners, and managers of the organization with varying levels of skills, attitudes, and agendas. If users are not following security policies, there might be a need for stronger administrative controls such as security awareness training or penalties for noncompliance this is the up to and including getting fired clause that HR puts in the employee manual. An organization can also implement a detectivecorrective control to enforce policies such as having the latest antivirus updates or operating system patches before the user is allowed on the network. People also represent the organizational structure and policies that drive security. Process represents how the organization delivers the service of IT. These are the procedures and standards that are put into place to protect assets. Processes must be up to date, consistent, and follow best practices to be effective. Process is one of the most important areas to test, because most attacks that result in significant loss have a component in which process has failed. Take, for example user account creation and decommission. Someone is hired, and a request is put into IT to create the appropriate accounts the new hire. Who is allowed to send the requestIs it any hiring manager or does it have to be one from Human Resources How is the request validated as legitimate Without strong process and the appropriate controls in place to prevent, detect, and correct, anyone can call and impersonate a hiring manager and request an account be created. This is significantly easier and quicker than trying to run a brute force, password cracking tool against a server. Bosch E Bike Tuning Software more. Technology represents the facilities, equipment, computer hardware, and software that automate a business. Technology enables people to accomplish repetitive jobs faster and with less error. Of course, technology also enables someone to do stupid things just as efficiently and faster. Misconfigurations and poorly implemented software can take a mistake and multiply its impact exponentially. Imagine leaving the door unlocked on a room that houses hardcopy files. Someone could potentially walk into the room and take files, but it would take a long time not to mention effort to hand carry those documents out to a car. Now, imagine misconfiguring a server in the DMZ to allow for access from the Internet to a key database server. Someone could download the entire database and not even leave a trace that they were there. This is why it is so important for a business to standardize on best practices and configurations that are known to work. Best practices tend to anticipate many of these scenarios. Evaluating security controls requires the auditor to look at a system with the eyes of a hacker and anticipate how things could be exploited to gain unauthorized access. Just because something shouldnt be exploitable, doesnt mean that it isnt. The only way to know is to test the system and the individuals who are tasked with monitoring and maintaining it should do the testing. Dig Into Nearly 3. Years of Free Classic Science Fiction.
