What is the purpose of DNS Cache Locking? It prevents an attacker from replacing records in the resolver cache while the Time to Live (TTL) is still in force.

Also to know is, what is DNS cache locking and what does it prevent?

Cache locking is a new security feature available with Windows Server® 2008. R2 that allows you to control whether or not information in the DNS cache can be. overwritten. You can protect the cache from cache poisoning attacks with it.

Likewise, what is the default size of the DNS socket pool? So again, 2500 is the default,…but keep in mind the larger the value,…

Moreover, what is the function of the NSEC record?

The NSEC record (record type 47) is provided by the Domain Name System Security Extensions (DNSSEC) to handle non-existent names in DNS. It links all the names in the zone and lists all the record types related to each name.

What are trust points in DNS?

A trust anchor (or trustpoint”) is a public cryptographic key for a signed zone. Trust anchors must be configured on every non-authoritative DNS server that will attempt to validate DNS data.

What is Dnscache service?

The DNS Client service (dnscache) caches Domain Name System (DNS) names and registers the full computer name for your computer. If the service is stopped, DNS names will continue to be resolved. However, the results of DNS name queries will not be cached and the computer's name will not be registered.

What is Rrsig?

A KSK stands for Key Signing Key. A KSK is a public/private key pair. A ZSK is a Zone Signing Key. A ZSK is a public/private key pair. The ZSK private key is used to generate a digital signature, known as a Resource Record Signature (RRSIG), for each of the resource record sets (RRSET) in a zone.

What is Dnssec unsigned?

The DNSSEC digital signature ensures that you're communicating with the site or Internet location you intended to visit. DNSSEC uses a system of public keys and digital signatures to verify data. It simply adds new records to DNS alongside existing records.

What is Rrsig record?

RRSIG-Records (RRset Signature) An RRSIG-record holds a DNSSEC signature for a record set (one or more DNS records with the same name and type). Resolvers can verify the signature with a public key stored in a DNSKEY-record. Algorithm: Cryptographic algorithm used to create the signature.

How does a DNS server work?

It is, in short, a system of matching names with numbers. The DNS concept is like a phone book for the internet. Instead, you just connect through a domain name server, also called a DNS server or name server, which manages a massive database that maps domain names to IP addresses.

What is a DNS key?

ABOUT DNSKEY LOOKUP
DNSKEY Records are used to publish the public key that resolvers can use to verify DNSSEC signatures which are used to secure certain kinds of information provided by the DNS system.

How do you implement Dnssec?

Setting up DNSSEC
  1. Verify that your TLD supports DNS Security Extensions.
  2. Speak to your IT department and 3rd-party domain service providers to obtain DNSSEC-specific requirements.
  3. Generate the zone signing key (ZSK) and key signing key (KSK) for your domain's DNS zone.

How does Dnssec validation work?

DNSSEC protects the Internet community from forged DNS data by using public key cryptography to digitally sign authoritative zone data when it comes into the system and then validate it at its destination.

How do I improve DNS security?

Infoblox expert: 10 keys to Improving DNS security
  1. Use dedicated DNS appliances- If you host your own DNS servers, make sure you use the right hardware.
  2. Keep DNS server software up-to-date – As with any other computer application, service, or protocol, new DNS vulnerabilities continuously crop up.

What is used to validate Dnssec responses?

DNSSEC validation
A recursive DNS server uses the DNSKEY resource record to validate responses from the authoritative DNS server by decrypting digital signatures that are contained in DNSSEC-related resource records, and then by computing and comparing hash values.

Which command do you use to verify local DNS settings?

Test DNS with dig & nslookup Commands
  1. In the Hostnames or IP addresses text box, type the domain that you want to test.
  2. Under Options, select the Show command check box.
  3. Under Nameservers, select the server that you want to use for the DNS query.
  4. Click Dig.

What is the DNS socket pool?

The socket pool enables a DNS server to use source port randomization when issuing DNS queries. This provides enhanced security against cache poisoning attacks. The socket pool is enabled with default settings on computers that have installed Security Update MS08-037 You can also customize socket pool settings.

When you set a service to start automatically with delayed start How long is the delay?

One of the side effects of Automatic (Delayed Start) services is that they do start later in the boot cycle. The default delay is 120 seconds (2 minutes). On fast hardware this might just be too long to wait.

What service does Dynamic Host Configuration Protocol DHCP provide?

The Dynamic Host Configuration Protocol (DHCP) is a network management protocol used on Internet Protocol networks whereby a DHCP server dynamically assigns an IP address and other network configuration parameters to each device on a network so they can communicate with other IP networks.

How are trust anchors distributed?

Trust anchors are often distributed as self-signed certificates. A configured DNSKEY RR or DS RR hash of a DNSKEY RR. A validating DNSSEC-aware resolver uses this public key or hash as a starting point for building the authentication chain to a signed DNS response.

What is conditional forwarding in DNS?

Conditional forwarders are DNS servers that only forward queries for specific domain names. Instead of forwarding all queries it cannot resolve locally to a forwarder, a conditional forwarder is configured to forward name queries to specific forwarders based on the domain name contained in the query.
