Default Do I need security?

I've been given a Nokia C3-00 (a nice phone, I like it a lot), and I'm not sure if I need to be looking for some kind of AV/Security to install on it.

Googling the subject has mostly led me to threads where people say that the version of Symbian that it has (S40, I think) cannot get infected or exploited, and thus there's no need for any security on this phone.

Is this true? If not, what would people recommend?

Also when I run Opera Mini (v5 ... I have v7 installed but it doesn't seem possible to change the default browser), I often get a warning that traffice is unencrypted and thus not safe for sensitive information. Does this mean that I'm not safe using email etc?

S40 is for lower spec phones than Symbian so Java vulnerabilities are most likely on the phone you've got. Anyway, both are fading platforms so they get less interest from hackers who are much more focused on Android, iOS and Windows Phone.

Most email is not encrypted so it is very vulnerable. Unless you know that you have encryption, your email messages should not contain passwords and other sensitive info.

Ah right, so S40 is not Symbian. I'm totally new to this kind of hardware.

Thanks for the links... so it's nonsense then that this OS is immune to malware? I don't put sensitive info in emails, it's just that the Opera Mini warning made me feel as if just logging in to my mail account might be enough for someone to have complete access to it.

Another question... if I connect my phone to my PC, is there any point in my using my PC AV to scan the phone?

No OS gets a free pass from conniving, cheating hackers and thieves.

PC AV looks for PC problems and the only crossover would be Java. But your phone uses Java Micro Edition (ME) MIDlets which are more restricted than the Java APPlets that run in your browser on your PC. So PC AV is unlikely to have a matching signature for a MIDlet on your phone.

For the unecrypted traffic, I believe that has to do with HTTP instead of HTTPS. Just check your addressbar, and make sure HTTPS is used for sensitive information like email, shopping, etc.

Even if the email itself isn't encrypted, you have to make sure the information transmitted is under HTTPS so unencrypted access is denied to all third-parties (other than the government).

Yes, that's what I thought.

Thanks, I understand.

Thanks JL, I didn't think to check if the phone was using https. I'll do that.

So, I'm still a bit unsure of whether I should be looking for some kind of internet security/AV to install.

I would err on the side of caution but:
  • does your phone multitask?
  • S40 phones should ask for permission to make changes?
  • I couldn't see anything free and useful on the Nokia store?

I checked, and yes the phone does use HTTPS, so thanks for the suggestion JL.

- Does it multi-task? I'm not entirely sure... I mean I don't really know what multi-tasking means in the context of mobile devices. I can listen to music on the media player while browsing, but once the browser is open it has no option to minimise thus precluding any other tasks... does that help?

- Permission to make changes... it always asks permission for installing and running an app for the first time, so far that's all it has asked though.

- Nokia store... no I couldn't find anything free and useful there either, or anywhere else for that matter. Hence my posting. There's an AVG app which is very affordable but I can't work out how to buy it... that's not for this site though sorry. Besides which I don't even know if it would work for my Nokia.

Thanks for the suggestions etc. Erring on the side of caution is always a good plan in my experience, when dealing with IT :-)

I looked for a bit for information on your phone, and on two places I found people saying that because of the OS, the malware cannot infect this phone.

So, I guess you don't have to worry. Of course, safe practices have to be followed, because being based on Java, there can be loopholes.

Also, I had a doubt whether antivirus would be available for your phone. I think there won't be.

I don't think you should invest money in going for an antivirus for your phone... don't think it's needed.

Multitasking means your security software could work while other programs are running. I'm pretty sure that S40 doesn't allow that so any security features you obtained would operate passively rather than be active while other apps are working.
