Hi there,

I have a huge problem in my job. Our security manager has banned Java and
JavaScript codes included via .js files to downloaded HTML or other
webbrowser enable files. He uses the firewall for this filtration. Almost 98
per cent of pages are broken down because of the incomplete pages. I am not
able to browse the web even for my professional needs. He told me that Java
applets and JavaScript are extremely dangerous especially for Windows
systems, but the Linux systems are safe.
I'd simply like to know if he is right. Thank you for correct information

Peter

They can be dangerous, yes. But if this is stopping you from doing your
work, perhaps he needs to come up with a better method. Banning java
outright is not really the best solution. Take this up with management.

In broad strokes, Java and Javascript on Windows is no where near as
dangerous as hysteriacal security managers would like them to be (but it
isn't completely "safe"). And Java on Linux is no where near as
"automagically safe just because it has a penguin on it" as hysterical
network managers would like it to be.

Oh, and remind them that Java and Javascript should have completely
different security assessments done on them. The name is the only thing that
they most have in common.

Your security manager is incompetant and not doing his job correctly.
