In the simplest case -- r/w access via SSH -- those who know the
login/password or possess the necessary private key have (full) access
to the repository. The repository can also be made accessible for
read-only via Git protocol (as a whole as well). This can be used for
simple write/read access discrimination.
If a more fine-grained control
is needed, third-party tools exist: gitolite:

Note that as Git does not suffer from a centralised VCS syndrome of
having a single repository shared by everyone involved, the problem
you're facing might not exist at all: every developer or a group of
related developers maintains their own repository and a "central"
repository (in whatever sense you're willing to put into it) is owned
by a special person or a group of persons.

In fact, git does not have any access control whatsoever. It relies
on what the underlying transport protocol allows it to do.

With ssh, you could wrap the commands into some script which checks,
the permissions on calling-in user or key (eg. restrict write access
on certain refs to certain people). You could do even more fancy
things like given everybody (or certain people) unrestricted write
access, but under the hood put their rename the updated refs
(eg. you can push 'master', but on the server, refs/heads/master
wont be overwritten, instead it goes to refs/heads/konstantin/master).

Some people (coming from strictly-central ideologies) might consider
git's access control angonsticity a drawback, but IMHO it's a very
good thing - git doesn't want to be a full-blown "out-of-the-box"
VCS (like, eg. clearcase), but more a lightweight toolkit to easily
build your own.

Git is independent of access control mechanisms - You can use whatever 
you want. For example, you could use the filesystem read/write 
permissions on a directory to control local access, or SSH permissions 
to allow remote access. See for example GitHub, which uses different 
protocols for different levels of access.

Git is independent of access control mechanisms to some degree,
however, if you use ssh and share a repository with other users you
will want to look into the core.sharedRepository config setting. Took
me a while to discover this.

Check 'git help config' and search for shared for the details.
