Network Security

Network Information service (formerly YP) is a means of distributing information to a group of machines. The NIS master holds the information tables and converts them into NIS map files. These maps are then served over the network, allowing NIS client machines to get login, password, home directory and shell information (all the information in a standard /etc/passwd file). This allows users to change their password once and have it take effect on all the machines in the NIS domain.

NIS is not at all secure. It was never meant to be. It was meant to be handy and useful. Anyone that can guess the name of your NIS domain (anywhere on the net) can get a copy of your passwd file, and use "crack" and "John the Ripper" against your users' passwords. Also, it is possible to spoof NIS and do all sorts of nasty tricks. If you must use NIS, make sure you are aware of the dangers.

Network security is a complicated subject, historically only tackled by well-trained and experienced experts. However, as more and more people become ``wired'', an increasing number of people need to understand the basics of security in a networked world. This document was written with the basic computer user and information systems manager in mind, explaining the concepts needed to read through the hype in the marketplace and understand risks and how to deal with them.

Some history of networking is included, as well as an introduction to TCP/IP and internetworking . We go on to consider risk management, network threats, firewalls, and more special-purpose secure networking devices.

This is not intended to be a ``frequently asked questions'' reference, nor is it a ``hands-on'' document describing how to accomplish specific functionality.

It is hoped that the reader will have a wider perspective on security in general, and better understand how to reduce and manage risk personally, at home, and in the workplace.

Network security is becoming more and more important as people spend more and more time connected. Compromising network security is often much easier than compromising physical or local security, and is much more common.

There are a number of good tools to assist with network security, and more and more of them are shipping with Linux distributions.

COMODO Internet Security 5.0.157302.1066 Beta/ 4.1.150349.920

Comodo Internet Security offers 360° protection against internal and external threats by combining a powerful Antivirus protection, an enterprise class packet filtering firewall, and an advanced host intrusion prevention system called Defense+. Internet Security combines the power of COMODO's award-winning Firewall and AntiVirus software to protect your PC from malicious software and Hackers. Best of all is FREE! Comodo Internet Security will help you detect and remove viruses, Trojans, and other malicious software and hackers, and keep them out of your computer. In one easy-to-use bundle that won't slow down your computer. Version 4.0 sees a major leap forward in security and usability with the addition of the new sandbox feature - an isolated operating environment for unknown applications. Under default settings, unknown applications are now automatically sandboxed so that they cannot make permanent changes to other processes, programs or data on your 'real' system.

COMODO Firewall or COMODO Antivirus canbe installed as standalone products by using the same setup.

Comodo Internet Security Features:
• Antivirus - The proactive antivirus system that automatically detects and eliminates viruses, Worms and Trojan horses.
• Firewall - The Firewall that constantly defends your system from inbound and outbound Internet attacks with a highly effective packet filtering firewall.
• Defense+ - A rules based intrusion prevention system that protects your critical operating system files from malicious processes, internal attacks and blocks unknown malware before it ever gets a chance to install. Defense+ now features automated sandboxing of unknown applications. The sandbox ensures untrusted (but harmless) applications are allowed freedom to operate whilst untrusted (and genuinely malicious) applications are prevented from accessing or infecting your computer. Now includes the revolutionary sandbox feature. Comodo Internet Security alerts you whenever potential malware attempts to attack or gain access to your system. The alerts are displayed as pop-ups at the right hand corner of your screen and allow you to allow or block the unrecognized activities, processes and connection attempts of running applications (CIS now even protects against 'drive-by-download' buffer overflow attacks.) Apart from expert advice in the form of 'Security Considerations', each alert now also features the innovative 'Threatcast' feature to help users arrive at an informed decision on how to react to the alert. The Threatcast system allows users to share their responses among the community of millions of CIS users worldwide. Whenever an alert appears, it contains a report of how other users have responded to the same alert. The report provides an additional guidance to even inexperienced users on making a decision to respond to the alert. Comodo Antivirus leverages multiple technologies, including Real-time/On-Access Scanning, On Demand Scanning and a fully featured Scan Scheduler to immediately start cleaning or quarantining suspicious files from your hard drives, shared disks, emails, downloads and system memory. The application also allows users to create custom scan profiles which can be re-used across all scan types and features full event logging, quarantine and file submission facilities. Comodo Antivirus detects and removes threats that are present on your machine and forms an additional layer of security on top of the threat prevention offered by the Firewall and Defense+ components. The heuristics scanning capability of the application identifies previously unknown viruses and Trojans. The Firewall component of Comodo Internet Security (hereafter known simply as Comodo Firewall) offers the highest levels of security against inbound and outbound threats, stealths your computer's ports against hackers and blocks malicious software from transmitting your confidential data over the Internet. Comodo Firewall makes it easy for you to specify exactly which applications are allowed to connect to the Internet and immediately warns you when there is suspicious activity. The Firewall Task Center allows you to quickly and easily configure all aspects of the Firewall. Advanced Features:
• Install the Antivirus as a standalone
• Install the Firewall as a standalone
• Install both Firewall and Antivirus Operating systems: Windows 7 / Vista / XP SP2 Changes in Version 4.1.150349.920, 09 June, 2010:
We made a small update today to address some of the issues you might be facing. It will be a two phase update. First phase which is today (9th June) addresses the following issues:
* Windows start menu can not be clicked if Defense+ is enabled
* Antivirus identifies some files as Corrupted
Second phase which is tomorrow(10th June) addresses the following issue:
* COMODO Antivirus decreases the performance of file downloads if installed as standalone. You should be receiving the automatic updater messages already and do not need to reinstall.
