Access control is only part of what makes a secure building. If a ground-floor window is left open, a guard at the front desk is not very effective at keeping burglars out. To protect against this, a building might automatically lock the windows or have reinforced glass to keep out intruders. For Linux, ExecShield (and similar projects like PaX and grSecurity) help ensure all the "windows" are closed and strong enough to deter a burglar. An office may have areas of the
building locked down and only accessible to employees with additional
credentials. This limits the damage that unauthorized people can do,
whether they came in via the front door or by climbing through a
window. In the Linux world, Security-Enhanced Linux (SELinux) provides
security in this way. -- ******************************************************************* PGP Fingerprint: 6695 794A B84E D922 88FB 73CC 6CBD 8036 B3CD 7304 We can't become what we need to be by remaining what we are ******************************************************************* |
