How well secure page from unauthorized access? I have a continuous attempt to crack the password.
Your question doesn't make sense as written, Please tell us more? Which password, to what service or host?
Where do you see the attempts? What technology is your website using? (you're talking about a website, right? ... so many questions One quick suggestion for you is to enable Extra Security on your domain, if you haven't done already. Once that is active, DreamHost will recognize brute force attacks and block them (or at least slow them down a lot)
You may also want to enable the Malware remove (you may read more about it on https://www.dreamhost.com/blog/dreamhost-security-team-fights-malware/)
