As such, the temptation is always there to make it &#8220;as easy as possible&#8221; to configure. Unfortunately this sometimes leads to making it <em>too easy<\/em> to configure. By <em>too easy<\/em>, I mean <em>insecure<\/em>.<\/p>\n<p>Regardless of the &#8220;hassle&#8221; that it creates, a backup server <em>must<\/em> be highly secured. Or to be perhaps even blunter \u2013 the <em>entire security of everything backed up by your backup server depends on the security of your backup server<\/em>. Having an insecure NetWorker server, on the other hand, is like handing over the keys to your datacentre, as well as having the administrator\/root password for every server stuck to each machine.<\/p>\n<p>Thinking of it that way, do you really want the administrator list on your backup server to include say, any of the following?<\/p>\n<ul>\n<li>*@*<\/li>\n<li>*@&lt;host&gt;<\/li>\n<li>&lt;user&gt;*@<\/li>\n<\/ul>\n<p>If your answer is yes, <strong><em>then you&#8217;re wrong<\/em><\/strong>*.<\/p>\n<p>However, datazone security isn&#8217;t <strong>only<\/strong> about the administrator list (though that forms an important part). At bare minimum, your datazone should have the following security requirements:<\/p>\n<ol>\n<li>No wild-cards shall be permitted in <em>administrator<\/em> user list definitions (server, NMC).<\/li>\n<li>No client shall have an empty <em>servers<\/em> file (client).<\/li>\n<li>No wild-cards shall be permitted in <em>remote access<\/em> user list definitions (client resources).<\/li>\n<\/ol>\n<p><strong>Note<\/strong>: With the advent of <em>lockboxes<\/em> in version 7.5, security options increase \u2013 it&#8217;s possible, for instance, to have passwords for application modules stored in such a way that only the application module for the designated host can retrieve the password.<\/p>\n<p>&#8212;<br \/>\n* I do make allowance for some <em>extreme<\/em> recovery issues that have temporarily required users to enter wild-card administrators <em>temporarily<\/em> where it was not possible to wait for a bug fix.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>A topic I discuss in my book that&#8217;s worth touching on here is that of datazone security.
