Could you recommend cheap certifications to get your foot in the door of the industry.
You're not going to get a lot for that kind of budget. There's also a risk, that if you go buy a certification test without some training first, then failing the certification may backfire. If it's just to impress your boss - then really you should be finding out what would impress him/her.
Brainbench offer online testing around $50 / test.
There are good learning resources on the ccure site as well as the topic Mark Hillick linked to.
I think this question is similar to the following questions, some of which I've answered -
- How do I get started with security
- Where do I go from here to be a pentester
- Pen testing practice box
To be honest, I wouldn't waste my time on most certifications that are in that price range because most of them are worthless (granted there are many that are more expensive that are also worthless). One that I would consider is looking at the new certifications developed by the guys at SecurityTube, which are in that price range. These guys are respected in the industry and their courses/certifications have received very favourable reviews.
I'd check these links out below, maybe consider buying books out of the 2-300 euros and get involved in the community (through Owasp, ISSA, your local security groups/forums etc) as I suspect you'll learn more and to be honest, many folk progress their career rather than through chalking up an endless list of certs. Possibly then as you become more involved, you'll have a larger budget and can go for a better certification that can progress your career.
