• Computer Immune Systems .
• Their role in the body is analogous to that of computer security systems in computing. Although there are many differences between living organisms and computer systems, we believe that the similarities are compelling and could point the way to improved computer security. Four examples of how we are applying ideas from immunology to today's computer security problems are a host based intrusion-detection method, a network based intrusion-detection system, a distributable change-detection algorithm, and a method for intentionally introducing diversity to reduce vulnerability. The analogy with immunology contributes an important point of view about how to achieve computer security, one that can potentially lead to systems built with quite different sets of assumptions, biases, and organizing principles than in the past. ...
• Immunologists have traditionally described the problem solved by the immune system as the problem of distinguishing "self" from dangerous "other" (or "nonself") and eliminating dangerous nonself. The problem of protecting computer systems from malicious intrusions can similarly be viewed as the problem of distinguishing self from nonself. Nonself might be an unauthorized user, foreign code in the form of a computer virus or worm, unanticipated code in the form of a Trojan horse, or corrupted data. ...
• What would it take to build a computer immune system with some or all of the properties of a natural immune system? Such a system would have much more sophisticated notions of identity and protection than those afforded by current operating systems, and it would provide a general-purpose protection system to augment current computer security systems. It would have at least the following basic components: a stable definition of self, prevention or detection and subsequent elimination of dangerous foreign activities (infections), memory of previous infections, a method of recognizing new infections, and a method of protecting the immune system itself from attack. ...

• Building a secure network of library computers is more important and more complicated than ever before. Simultaneously, the network administrator must protect the library's networks and systems, ensure public access computers are always available, and enable legal access to the library's subscription-based resources. It takes a large-scale, multi-faceted effort to manage library computer and network security, and it will involve everyone from administrators, to computer technicians, to librarians, to staff.
• It requires a broad understanding of the library security principles which are embodied in library policies and procedures, and it involves creating a multi-tiered security system that addresses general security issues as well as user security, workstation security, server security and network security. In addition, this system must be constantly monitored and updated as new threats arise.
• These pages on library computer and network security are designed to assist you and your library in this process. Because of the prevalence of Windows-based computers in libraries, these pages focus on security for computers and networks using the Windows family operating desktop and server operating systems. ... For good starting points for the Macintosh and Linux operating systems, see Linux and Linux Security Resources on the Internet and Macintosh Security. For Novell networks, see Novell Security Information.
• Most libraries already have some components of a security system in place, but there's a good chance that after working through these pages you'll find you need to add more layers to it. The system you create will be unique to your library; use these pages as a blueprint for security, adding and subtracting according to your specific needs. ...

• Security-Enhanced Linux.
• Security-Enhanced Linux (SELinux) is a Security-Enhanced version of GNU/Linux, which was primarily developed by the US National Security Agency (NSA) and released to the open source development community. ...
• From NSA Security-enhanced Linux Team: .
• "NSA Security-enhanced Linux is a set of patches to the Linux kernel and some utilities to incorporate a strong, flexible mandatory access control (MAC) architecture into the major subsystems of the kernel. It provides a mechanism to enforce the separation of information based on confidentiality and integrity requirements, which allows threats of tampering and bypassing of application security mechanisms to be addressed and enables the confinement of damage that can be caused by malicious or flawed applications. It includes a set of sample security policy configuration files designed to meet common, general-purpose security goals. ...
• Security-enhanced Linux is a research prototype of the Linux kernel and a number of utilities with enhanced security functionality designed simply to demonstrate the value of mandatory access controls to the Linux community and how such controls could be added to Linux. The Security-enhanced Linux kernel contains new architectural components originally developed to improve the security of the Flask operating system. These architectural components provide general support for the enforcement of many kinds of mandatory access control policies, including those based on the concepts of type enforcement, role-based access control, and multi-level security. ...
• The security-enhanced Linux kernel enforces mandatory access control policies that confine user programs and system servers to the minimum amount of privilege they require to do their jobs. When confined in this way, the ability of these user programs and system daemons to cause harm when compromised (via buffer overflows or misconfigurations, for example) is reduced or eliminated. ... It has no concept of a "root" super-user, and does not share the well-known shortcomings of the traditional Linux security mechanisms (such as a dependence on setuid/setgid binaries). ...
• The security of an unmodified Linux system depends on the correctness of the kernel, all the privileged applications, and each of their configurations. A problem in any one of these areas may allow the compromise of the entire system. In contrast, the security of a modified system based on the security-enhanced Linux kernel depends primarily on the correctness of the kernel and its security policy configuration. While problems with the correctness or configuration of applications may allow the limited compromise of individual user programs and system daemons, they do not pose a threat to the security of other user programs and system daemons or to the security of the system as a whole. ...

• Security company Network Associates Technology announced on Friday that it plans to offer an integrated software security system for both desktop and server computer systems by next June, challenging similar moves by its rivals. ...
• -based company dubbed the new integration plan its "end-node security strategy," referring to its focus on running the security software on servers and PCs rather than on a separate network device. The strategy is the most complete indication to date of how Network Associates plans to use the products from its recent acquisition of Entercept, an intrusion detection company. ...
• "Everyone is looking at doing this," said Ryan McGee, director of product marketing for Network Associates' system protection solutions. ... We think that Network Associates is one of the only vendors in the world that has the pieces to put this together in the near term--in the next year. ...
• Other security companies have already started moving toward integrating network-based security systems, which analyze network traffic to discern threats, and host-based security systems, which watch system behavior to detect potentially hostile programs. ...
• "At the end of the day, integration is going to win," said Tim McCormick, vice president of marketing for security company Internet Security Systems, which announced on Tuesday that it would integrate a variety of security functions into a single network device. ...
• For example, the company will have a single intrusion-prevention product that runs on desktop and server computer systems. ...
• For Network Associates, the new strategy allows it to integrate the host-based intrusion detection software it gained from its acquisition of Entercept in January. By bringing together those applications with its network monitoring and management software such as e-Policy Orchestrator, the company plans to offer a unified approach for its customers. ...
• "It is a customer problem that we all hear: There are too many agents, too many consoles to manage," Network Associates' McGee said. ...
• Moreover, the move highlights the company's change in focus on desktop computer systems--from combating viruses to stopping general intrusions, he said. Security on PCs today generally consists of two types of programs: antivirus software and personal firewalls. Network Associates and Symantec currently offer both types of software, and other companies, such as Zone Labs with its ZoneAlarm firewall and Trend Micro with its antivirus system, offer standalone products. ...

• Network security: it's not just about computers anymore.
• Network security: it’s not just .
• Once concerned mainly with credit card numbers and confidential data, participants in the new economy were rudely reminded that security is not just about information and that critical business operations can be compromised in other ways. In fact, there are three main parts to security:.
• Confidentiality: This is typically what comes to mind when people think about security. ...
• Businesses now must take a more proactive and strategic look at network security management. ...
• Here are the key considerations for companies taking a more “holistic” approach to network security management:.
• Know the network: During the recent denial-of-service attacks, one of the systems that was used to attack other sites was a remote router for a university, which was literally sitting out in the middle of nowhere collecting and passing data. Some of the sites that were attacked were connected to it, but these companies did not necessarily consider the router a key part of their network. ... This illustrates why it is crucial for systems administrators to get a handle on exactly what is on the network and what impacts it. They must map the network and know every entry way and every point at which their system has trust with another. ...
• Update the network: One of the best steps systems administrators can take to protect their network costs nothing: keeping up-to-date on operating system patches and “hot fixes. ...
• Dedicate time and people to security: Being proactive when it comes to security means investing the time up front to address potential problems. For some companies, this may mean that they need an extra person who focuses strictly on security, maintaining patch levels and knowing the network. Most security problems and attacks can be avoided by investing one simple but valuable resource: time. ...
• Address security across the entire network—whether big or small: Any company, no matter its size, can become a target for hackers not necessarily for its own assets but as a place to launch attacks. ... Even if a company does not need to vigilantly protect its own data, it is important for every organization to show it has done due diligence with respect to security so that it will not be liable for damages. Companies, especially smaller ones, however, do not necessarily have to spend millions of dollars on security. ...

• operations or other circumstances that might impact information security; and.
• If you give another organization access to your records or computer network, you should make sure they have good security programs too. ...
• When setting up a security program, your business should consider all the relevant areas of its operations, including employee management and training; information systems, including network and software design, and information processing, storage, transmission and disposal, and contingencies, including preventing, detecting and responding to a system failure. Although the security planning process is universal, there’s no “one size fits all” security plan. ...

• a Personal firewall - a software application which normally filters traffic entering or leaving a single computer, and .
• a traditional Firewall, normally running on a dedicated network device or computer positioned on the boundary of two or more networks or DMZs (Demilitarized zones). ...
• Firewalls (in the sense of computer networking devices) come in several categories and sub-categories. They have the basic task of preventing intrusion from a connected network -- but they try to accomplish this in varing ways. ...
• network layer firewalls .
• Network layer firewalls operate at a (relatively low) level of the TCP/IP protocol stack as IP-packet filters, not allowing packets to pass the firewall unless they meet the rules defined by the firewall administrator or applied by default (as in some inflexible firewall systems). ...
• Proxies make tampering with an internal system from the external network more difficult, and misuse of one of its internal systems would not necessarily cause a security breach exploitable from outside the firewall (as long as the application proxy remains intact and properly configured). Conversely, intruders may hijack a publicly-reachable system and use it as a proxy for their own purposes; the proxy then masquerades as that system as far as others are concerned. While use of internal address spaces enhances security, crackers may still employ methods such as IP spoofing to attempt to pass packets to the target internal network. ...
• Firewalls often have network address translation functionality, and the hosts protected behind a firewall commonly use so-called "private address space", as defined in RFC 1918. Administrators often set up such scenarios in a effort (of debatable effectiveness) to disguise the internal address or network. ...
• It requires considerable understanding of network protocols and of computer security. Small mistakes can render a firewall worthless as a security tool. ...
