Useful or Interesting Articles

From time to time I come across useful articles do with networking, firewalling or Linux. Here is a list:-

• A useful article on choosing Windows Network Time clients.
  
  
• Web Application Security, particularly using Open Software, is of increasing concern in this modern times. This Guide sets out a framework for securing web applications.
  
  
• The firewall is a fundamental component of all computer security strategies. However, the simple firewall is not only restricted to safeguarding the user's valuable information - it can also optimize the user's bandwidth. This article, by Jeroen Wortelboer and Jan Van Oorschot discusses how Linux firewalls can be used to shape traffic to optimize quality of Internet service and to reduce vulnerability to DoS attacks.
  
  
• You can run, but it is difficult to hide on the internet, which is why you should read this article on host detection. If you didn't like that much, why not do some passive host detection instead?
  
  
• I can never find this when I want to. Anyway, here is the Web Robots page.
  
  

It is a sad fact that more and more machines are being attacked and trojaned. Here are some links that give information about the process and what you can do about it.

• You can obtain tools for detecting whether you have been compromised, as well as a series of links to other useful information. This is the chkrootkit site.
  
  
• This is another useful site that has information about dealing with break-ins as well as tools such as IDSs and such-like.
  
  
• If you have been broken into, this is the "official" cert way of recovering from a root compromise.
