Java's sandbox model is far more secure than Javascript. But we see Javascript
running on practically every web page so it is very counter productive to
disallow it through a firewall. There are really several points:
1/ All mobile code is a security risk, since it allows code genrated in a
potentially hostile environment to run on your trusted machine,
2/ Interpreted mobile code is more dangerous than compiled code because the
code itself can be manipulated dynamically, preventing proper verification
before execution (IIS Unicode is an example of this).
3/ Mobile code should run at least privilege and in a sandbox.
By looking at the risks, Java is the least dangerous form of mobile code, but
still not risk free.
Oh and the Brown Orifice exploit last year belies the statement " more computer
damage is caused by fire and weather than
by Web-based hostile Java applets. Even insects cause more damage than Java,
so why aren't those bugs front-page news, too"
since it caused many places to spend significant time and resources to upgrade
their Netscape browsers.
The authors of Brown Orifice, to their credit, never exploited it and really
benefited the user community by demonstrating problem with no maliciousness.
BUt it does show that, although the Jave model is fairly secure, the
implmentation is critical.

Subject: [fw-wiz] article on java in infosecurity mag
Howdy,
Have othere here seen and read the recent article in information security
magazine;
http://www.infosecuritymag.com/articles/june01/columns_curmudgoens_corner.shtml
The gist of the article boils down to these statments:
Hostile Java applets are a perfect example of an over-hyped security
threat that has no basis in reality. For years, we've been warned
about crackers and unethical Web-site operators surreptitiously placing evil
Java code on Web servers. The hostile applets would secretly steal or sabotage
data on the PC of any visiting user. But after six years of warnings, such
exploits have never materialized.
Hostile applet attacks remain theoretical for two reasons. First, what few Java
vulnerabilities have appeared have been fiendishly hard to exploit. And second,
such an attack would provide little benefit to attackers--e-mail is a much more
efficient mechanism for spreading hostile code. To put the situation into
perspective, more computer damage is caused by fire and weather than
by Web-based hostile Java applets. Even insects cause more damage than Java,
so why aren't those bugs front-page news, too?
The FUD surrounding Java is a lesson in the perils of believing everything
you hear. To understand why this non-threat has assumed such epic proportions,
you have to go back to 1995.

Are folks in the industry changing their stances on the security
