Antivirus Firewall ?

Hi do we use any protection on the Raspberry pi whilst using Risc or one of the other OS and if so which would be the best to use, Brian.

AFAIAA there are very few hackers who would understand RiscOS

RiscOS, Unix, Linux, OSX do not have the vulnerabilities which are worth exploiting by Hackers. Changing any Default Passwords is normally sufficient.

For Raspbian look at user-friendly firewall (ufw).


For RiscOS don't bother, running it as a internet client machine is going to be safe enough because it's not a viable target for the hackers. They choose Windows as their primary target because a) it started with no security and the bolt-on security that Microsoft added wasn't fit for purpose, b) there's an exceedingly large number of un-patched machine out on the public network and c) Windows is run by un-sophisticated users who have weak passwords and don't understand the risks of clicking random links or running random executables on their machines.

If you're sophisticated enough to run RiscOS you're probably smart enough to know how to avoid any risks.

I tried RiscOS on a RPi for about an hour and decided it wasn't for me because it really is a club for the old geeks who played with their BBC Micros.

Even if someone was attempting to hack your RISC OS, what program is there to accept the connection? If you are running a server application, or other application that will accept an incoming connection it likely will not allow outsiders to make any modifications to your system (as such commands are likely not supported), with the exception of things like FTP, which should only allow making directories, and writing files (and that only inside a directory you specify). The one big exception is running a VNC server on RISC OS, though you would know if you have started a VNC server.

In RISC OS you will know if you are running something that will accept a connection. This is not like *n*x, MS-Windows, etc that have background services that are running to allow such things to happen behind the scenes.

And there is the fact that RISC OS is not a target for hackers. There are maybe a dozen viruses for RISC OS, most of which will not even work on 32-bit addressing only RISC OS 5 (two possible exceptions were written in the !Boot Obey file of applications, and infect the !Boot Obey file of other applications).

So, unless RISC OS becomes a whole lot more popular than it is, there is no reasonable need for a firewall or antivirus. Unless someone starts distributing RISC OS with modules that will accept an incoming connection and allow to much access, and has these modules active by default.

That does not appear to be for RiscOS :?

So, RiscOS goees with the "Security by Obscurity" virus and malware protection idea, huh? Awesome. :roll:

Just because there are only a handful of known existing viruses/malware for the platform doesn't mean that you are safe, that your data/info is safe, or that your network/networked devices are safe, or that targeted malware won't be created in near future, or that the existing malware wont be modified.

Security by Obscurity is just about the most retarded form of security there is, and it is those that belive in it that make up the vast majority of current botnets.

Nice try.
Yes, but here this is not the case.

There is no way for a firewall to protect a system with no opened ports.
And there is no way for an antivirus to protect a system... without viruses.
Make viruses and server software first, and we'll make an antivirus + firewall to counter your efforts ;)

And no, this is not security by obscurity, since RISC OS source code is available. Anyway, there are other ways to enhance the protection of the OS. Zero page effort is one of them, and it tries to solve a real problem: stability.

Linux is not impenetrable.. which is why Ubuntu comes with an anti-virus app. OSX is also not the rock we've all been told. Macs have been getting hit the last couple of years. Read about people getting locked out of Safari with a malicious virus warning.

As for a firewall though.. if you're using a modem, it should have a firewall available within the configuration app.

What app do you mean? If you mean ClamAV, it does not come installed by default. There are thousands of apps in the repositories for people whom might be interested in them - it does not mean that they are necessary or even useful to most people. Furtermore, ClamAV is according to Wikipedia "useful for computers (typically, servers) which will pass on files to MS Windows users. [It does] not look for Linux-specific threats."

Well, I'm running ssh, ftp, and http servers on my RISC OS Pi2. But, still, I agree with most of what you wrote. My servers are for use only on the subnet. For most people, the NAT router does most of the "firewall" work for a client machine. That means the attack vector has to be thru the web browser, and specific to both the browser and the OS. Netsurf is pretty much a niche browser (albeit with a loyal following) - and RISCOS - LOL. So, I don't stay up at night, dreaming about the viruses.

The last time I had to deal with a virus on RISC OS machines was in the mid 80s, on a network of about 40 Archimedes. It was a virus that concealed itself as a spritefile and exploited the iconsprites command. It could not do much damage. Just switch off and reboot, a matter of seconds - remember that RISC OS has in the main been stored on readonly media. In some ways RISC OS is inherently unsafe; but that has to be qualified, because many of the dangers to which Windows is exposed are simply not there. Automatic upgrades and virtual memory, with all their advantages and insecurities, are not there to be exploited. The user has far greater control of what is going on. It would be quite possible for a malevolent person to be a nuisance to RISC OS users, but not to spread mayhem to thousands of machines. Trust may not always be wise, but it makes life a lot sweeter.
