Right-click on the domain controller and choose <strong>DNSSEC &gt; Sign the zone<\/strong>.<\/li>\n<li>Launch the <em>Zone signing wizard<\/em> and click Next.<\/li>\n<li>Choose <strong>Customize zone signing parameters<\/strong> and proceed.<\/li>\n<li>In the <em>Key Master<\/em> window, select the option that indicates the DNS server is the Key Master, and click Next.<\/li>\n<li>On the <em>Key Signing Key (KSK) interface<\/em>, click Add and fill in necessary fields according to your organization\u2019s needs, then click Next.<\/li>\n<li>For the <em>Zone Signing Key (ZSK)<\/em> option, click Add, fill in the required details, and save.<\/li>\n<li>On the <em>Next Secure (NSEC)<\/em> screen, provide details. NSEC records help to prove that a domain name does not exist.<\/li>\n<li>On the trust anchors page, enable both <em>Enable the distribution of trust anchors for this zone check<\/em> and <em>Enable automatic update of trust anchors on key rollover<\/em>, then click Next.<\/li>\n<li>Enter DS details on the <em>Signing and Polling Parameters<\/em> screen, then proceed through the summary and finish the setup.<\/li>\n<li>Verify the configuration by going to <em>Trust point &gt; ae &gt; domain name<\/em> in the DNS Manager.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>Configure Group Policy<\/strong><\/p>\n<ul>\n<li>Launch the <em>Group Policy Management<\/em> program.<\/li>\n<li>Navigate to <em>Forest: Windows.ae &gt; Domains &gt; Windows.ae<\/em>, right-click on <em>Default Domain Policy<\/em>, and select Edit.<\/li>\n<li>Under <em>Computer Configuration &gt; Policies &gt; Windows Settings<\/em>, access <em>Name Resolution Policy<\/em>.<\/li>\n<li>In the right pane under <strong>Create Rules<\/strong>, input <em>Windows.ae<\/em> in the Suffix box.<\/li>\n<li>Check the boxes for <strong>Enable DNSSEC in this rule<\/strong> and <strong>Require DNS clients to validate name and address data<\/strong>, then click Create.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>DNS Socket Pool<\/strong><\/p>\n<p>DNS Socket Pool increases security by randomizing source ports for outgoing queries. To adjust the socket pool size:<\/p>\n<ul>\n<li>Open <em>PowerShell<\/em> as an admin and run the command:\n<pre><code>Get-DNSServer<\/code><\/pre>\n<\/li>\n<li>Check the current size with:\n<pre><code>Get-DnsServerSetting -All | Select-Object -Property SocketPoolSize<\/code><\/pre>\n<\/li>\n<li>To increase the socket size, run:\n<pre><code>dnscmd \/config \/socketpoolsize 5000<\/code><\/pre>\n<\/li>\n<li>Restart your DNS Server to apply changes.<\/li>\n<\/ul>\n<\/li>\n<li>\n<p><strong>DNS Cache Locking<\/strong><\/p>\n<p>DNS Cache Locking preserves cached DNS records from being overwritten during their TTL, adding data integrity. Check the current locking percent:<\/p>\n<pre><code>Get-DnsServerCache | Select-Object -Property LockingPercent<\/code><\/pre>\n<ul>\n<li>To set the locking percent to 100, if it\u2019s not already:<\/li>\n<\/ul>\n<pre><code>Set-DnsServerCache \u2013LockingPercent 100<\/code><\/pre>\n<\/li>\n<\/ol>\n<p>Implementing these measures will significantly secure your DNS Server.<\/p>\n<h3>Additional Resources<\/h3>\n<ul>\n<li><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.thewindowsclub.com\/change-dns-server-using-command-prompt-and-powershell\">How to change DNS server with Command Prompt or PowerShell<\/a><\/li>\n<li><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.thewindowsclub.com\/what-is-dns-aging-scavenging\">Enable and Configure DNS Aging &amp; Scavenging in Windows Server<\/a><\/li>\n<li><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.thewindowsclub.com\/install-and-configure-dns-on-windows-server\">Install and configure DNS on Windows Server<\/a><\/li>\n<li><a target=\"_blank\" rel=\"nofollow noopener\" href=\"https:\/\/www.thewindowsclub.com\/how-to-change-dns-settings-in-windows-7-vista\">Change DNS settings in Windows 11 easily<\/a><\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Domain Name System Security Extensions (DNSSEC) is a set of security protocols designed to protect the integrity of the DNS protocol.
