5 Questions To Ask Before Investing in A DNS Security Service
The Domain Name System (DNS) is a vital component of Internet Infrastructure which provides amechanismfor translating hosts name into Internet Protocol (IP) addresses. Thus, it is a process of name-to-address mapping. It is not possible for any of us to remember the IP addresses of all the sites we want to access.
Besides, a single site can have more than one IP addresses. DNS saves us from memorizing all the IP addresses. If DNS is not available to your computer, you will be unable to access resources on the Internet, others will not find you.
Thus, DNS supports Internet Infrastructure by distributing a robust mechanism. DNS not only helps in forward resolution, it also helps in inverse resolution. It has three major components. They are the server, the database, and the client.
Unfortunately, IP addresses are surrounded by many security weaknesses and DNS cannot stay immune from these threats of IP addresses. As DNS doesn’t have any security service of its own, it is necessary for an individual organization to protect their DNS from such threats.
This is all due to the lack of integrity and authenticity of DNS. False information within the DNS can cause dangerous exposures. Most of the major weaknesses within the DNS are of the following categories: cache poisoning, information leakage, client flooding, compromise of the server’s authoritative database.
Anyone can take advantage of these weaknesses intentionally formulating misleading information of your query. Besides, there are masquerading attacks. Client flooding means when you send out a query and receive thousands of responses. By information leakage, an intruder can use the uncovering unused IP addresses.
All these are potential threats to you and the DNS. To protect DNS when you are investing on security services you need to ask a few fundamental questions to yourself and the company you are going to rely on.
1. Products Services
The very first query is to know what the services are that your product is providing. This may sound easier to answer, but not so actually. a company, they will use catchy phrases but can’t answer specifically. Choose one who can specify their services. You need a solution and the support and service that the company can provide you if you purchase their products. BlueCat is my personal favorite as they provide extremely professional and flawless DNS security services
2. Number of Authoritative Name Servers
Next, you need to know how many authoritative name server you are having. You should at least have two authoritative name server, but higher the server higher you are protected.
3. Handling DNS Remotely
You should ask if youcan remotely handle your DNS server which will be easier and comfortable. But you must be cautious that any brute force is not enjoying your remotely handling process even if your servers are locked.
To immune its DNS, a company needs to invest a lot. Proven security solutions should provide tangible benefits quickly with standard increased efficiency line along with significant savings.
5. RAM Of DNS
You need to know the RAM that is installed and available in your DNS because having limited RAM is often a of limitation of DNS services. Your DNS server should possess more than enough quantity of RAM.
As security waits for no one, you should better be well-informed. Do not waste your time and don’t get trapped in buzz words. Investigate before investing. Have aclear and concise plan and stay secured.
