  • There are hundreds--if not thousands--of techniques used to compromise both Windows and Unix-based systems. Malicious code and new exploit scripts are released on a daily basis, and each evolution becomes more and more sophisticated. Keeping up with the myriad of systems used by hackers in the wild is a formidable task, and scrambling to patch each potential vulnerability or address each new attack one-by-one is a bit like emptying the Atlantic with paper cup.

  • Often, several of these testing techniques are used together to gain more comprehensive assessment of the overall network security posture. For example, penetration testing usually includes network scanning and vulnerability scanning to identify vulnerable hosts and services that may be targeted for later penetration. Some vulnerability scanners incorporate password cracking. None of these tests by themselves will provide a complete picture of the network or its security posture. Table 3.1 at the end of this section summarizes the strengths and weaknesses of each test.

  • Not all threats are intended to be malicious, but they can exhibit the same behavior and can cause as much harm—whether intended or not. Unfortunately, many networking infrastruc- tures have to deal with the increasing issue of viruses and malware that can be found on compromised computing resources and pose unintentional security threats from unsus- pecting employees. It is important to understand what types of attacks and vulnerabilities are common and what you can do at a policy level to guarantee some degree of safe networking.

  • The primary reason for testing the security of an operational system is to identify potential vulnerabilities and subsequently repair them. The number of reported vulnerabilities is growing daily; for example, the number of new information system vulnerabilities reported to the Bugtraq2 database has more that quintupled since the start of 1998, from an average of 20 to over 100 per month. The number of computers per person in many organizations continues to rise, increasing the demands on competent and experienced system administrators.

  • Evaluation of system security can and should be conducted at different stages of system development. Security evaluation activities include, but are not limited to, risk assessment, certification and accreditation (C&A), system audits, and security testing at appropriate periods during a system’s life cycle. These activities are geared toward ensuring that the system is being developed and operated in accordance with an organization’s security policy.

  • Welcome to Hacking For Dummies. This book outlines computer hacker tricks and techniques — in plain English — to assess the security of your own information systems, find security vulnerabilities, and fix the vulnerabilities before malicious and criminal hackers have an opportunity to take advantage of them. This hacking is the professional, aboveboard, and legal type of security testing — which I call ethical hacking throughout the book. Computer and network security is a complex subject and an evermoving target.

  • This module will address password security. Although user names and passwords are a familiar technology, most people are not aware of the inherent weaknesses in many of the different passwordbased authentication schemes in use today. These weaknesses are important to understand since many networks would be compromised if passwords on just a few key machines (such as firewalls, DNS servers, or Windows domain controllers) were known to an attacker.

  • The number of alerts the Threat Analyzer can display has a direct correlation to your system's memory. Since you can access the Central Manager from the local host or a remote connection, this depends on the machine used for the Central Manager logon. The memory overhead for alerts, including the code base and Java virtual machine, is approximately 1 KB per alert when there are at least 10,000 alerts in the Threat Analyzer (more KBs when there are fewer alerts). McAfee recommends 1 GB of RAM in your system which enables you to handle up to 1,000,000 total alerts. If...

  • The and files are protected by access controls on the $VCLOUD _ HOME/etc folder and the files themselves. Do not change the permissions on the files or folder as it may either give too much access, reducing security, or restrict access too much, stopping the VMware vCloud Director software from working. In order for the access controls to properly work, physical and logical access to the VMware vCloud Director servers must be strictly limited to those with a need to log in and only with the minimal levels of access required.
