4 Important Benefits of Utilizing VPS Hosting

Many companies are utilizing the power and flexibility of VPS hosting. A VPS or virtual private server is often the perfect hosting choice for businesses of all sizes. Here are four major benefits of choosing to host on a virtual private server.

1. User Controlled Environment

It’s important that someone has control within a hosting environment. If you’re using a virtual private server, you’re able to control how it operates. Using shared hosting plans might mean waiting days to have new software packages installed. Other hosting packages may severely limit what you can install based on security rules. Using private hosting helps to ensure you control both how and what kinds of software enter your server.

2. Not Sharing Hosting With Other Users

Many people have had bad experiences with shared hosting packages from unreliable companies. You’ll never know who you’re sharing space with while using a shared server. If one person or company makes a mistake, everyone on a shared server knows about it. You don’t want to deal with slower speed because one person is using all available resources. Many businesses prefer the privacy and control that comes with utilizing a virtual private server. You’ll have much more freedom while utilizing VPS hosting instead of sharing bandwidth with other users.

3. VPS Containers Make Scaling Simple

One drawback with using shared hosting is the effort it takes to scale up. Virtual private hosting networks host your system within a type of container. Many hosting companies will have different container sizes available. A container-based pricing system enables a business to scale up when the time is right. If you’ve got an upcoming launch, it’s best to scale up ram and hosting needs with a few mouse clicks. You don’t need to feel trapped in a larger hosting package after a big event dies down. Private hosting enables to you scale down hosting as fast as it’s scaled up.

4. Private Hosting is More Affordable Than Ever

In the past, companies have had to spend higher prices for private hosting. Fortunately, innovations in technology have made virtual private server hosting extremely affordable. Private hosting prices are much more comparable to shared hosting than they’ve been in the past. Every business owner can rest assured that private hosting packages won’t cost a massive amount of money.

In closing, there are several beneficial reasons to implement VPS hosting. Virtual private servers enable businesses to have more freedom and control versus using shared hosting packages. Private hosting is an affordable and dependable solution that many companies utilize.

Why The DNS Firewall Is More Important Than You May Realize

Hacker in the office

Taming DNS Traffic

Without doubt, this is a prodigious time in internet security research. Security researchers regularly develop amazing new strategies for stopping hackers in their tracks. Lately, the DNS firewall has become one of the most talked-about tools for protecting corporate assets. Don’t confuse DNS firewalls with traditional firewalls, which are useful but rather blunt security instruments. Because security experts have eliminated numerous security vulnerabilities, many hackers have focused almost exclusively on exploiting DNS traffic. DNS traffic is unique because it comprises the fundamental connective tissue of the internet. Without the ability to send and receive DNS requests, you simply can’t connect to the internet.

Rerouting And Analysis

Installing a DNS firewall is a major step towards securing your information systems. To get the most out of your firewall, you’ll likely have to make adjustments to your DNS resolution from time to time. Be sure to redirect all port 53 traffic to your recursive DNS server. Though you might not be familiar with this terminology, you’ve likely seen this type of redirection firsthand if you’ve used wireless internet at a hotel. In most hotels, guests who use the Internet are redirected to verification pages where they are asked to agree to specified terms of service.

Also known as secure DNS resolvers, DNS firewalls faithfully route all incoming data packets into predetermined pathways. Unauthorized users will experience great frustration if they persist in their efforts to circumvent your DNS firewall. To date, security researchers have uncovered no consistent tactic for overriding a properly-configured DNS firewall–at least not from a known vector of intrusion. Besides simply blocking suspicious packets from known bad actors, the DNS firewall logs all incoming traffic for analysis. Though unlikely, it is certainly possible that a hacker could attack your system from a custom DNS server that has never been used before. As long as you regularly check your DNS logs for telltale signs of ingress, your firewall should prove fully capable of meeting your needs.

Understanding The High Stakes Of Data Security

These days, more and more Canadian companies are recognizing the need for above-average data security. It is deeply important to understand the stakes involved here. Any breach of data can lead the public to question your organization’s professionalism. These incidents can create even more public relations damage if sensitive customer information is exposed. Recent history is full of examples of hacker intrusions that resulted in great embarrassment for responsible parties. Although it isn’t the only way you can protect your organizational data, installing a secure DNS resolver can certainly lay the foundation for a more secure system.

Canadian Government Offers New DNS Protection

DNS protection is a vital part of every IT security system. It isn’t perfectly foolproof, but it can help prevent almost any type of digital attack, so nobody should go without it. Most people already use some form of it, but the fact that digital threats are constantly evolving means that DNS security programs also need to keep changing. The Canadian Internet Registration Authority recently made a significant contribution in the fight against digital crime by releasing its firewall to the public.

What Is DNS?

A domain name system, or DNS, is a core part of how most people access the Internet. It allows a computer to convert a domain name that a human can understand into an IP address that a network can understand. That makes it one of the most important tools in modern networking, both because it enables users to navigate the Internet and because it can be used as part of a security system.

There are a variety of services that interact with the DNS to improve the user’s experience. Most of them work by identifying specific domain names, comparing it to a list, and taking an action if the name shows up on that list. Most DNS protection programs work by maintaining a list of hostile sites and blocking access to them. At the most basic level, this can help make sure that users do not visit a site that will infect their computer with malware. They can also recognize servers that malware often causes a computer to visit, and prevent access to them to make sure that an infection does not cause any serious damage. Since the list of servers that these services need to block is always changing as new attacks get developed, the most useful protection programs are those that receive regular updates and support. If you would like more information, www.bluecatnetworks.com has additional resources available.

What Is The New Program?

The new DNS firewall from CIRA is a program that is based in the cloud and intended to protect organizations from digital attacks, with a particular focus on ransomware. That makes it particularly appealing to many consumers because ransomware attacks, which lock down a computer until the user pays to have the malware removed, have been getting quite a bit of publicity lately. That emphasis on ransomware does not prevent the program from being useful against other attacks, so it can easily fit into most current security systems.

The program is also designed for easy implementation. The new DNS protection program relies on cloud computing, so installation is convenient and updates can come quickly. Those updates will be particularly valuable, since the program’s connection to a major IT group will ensure that it gets the support that will make it a powerful tool against hackers.

6 Most Common DNS Attacks You Should Know About

Every invention parallels with a series of threats hanging on it’s safety. One of the most important systems in global network is DNS which is liable to be attacked every now and then due to it’s versatility. Attackers around the world are always putting an eagle’s eye to damage the network in order to get profit. Obviously, there are several server administrators who incessantly curtail the chances of DNS attacks. However, DNS system is so vulnerable that attacks are bound to suffer it. Let’s get to know about some of the most common attacks servers come across:

1. DNS Amplification:

Often DNS server looks for recursive answers to queries and thus pave way to the attackers to launch their attacks to other DNS servers with the help of recursive lookup. www.bluecatnetworks.com provides better protection against DNS amplification than other services.


2. Denial Of Service:

Traffic is common in DNS network but without attacks, it manages to tackle the traffic easily. However, attackers don’t sit quietly and interfere here too. They put a lot of traffic through detrimental bots to any targeted IP address. Hence, legitimate queries remain unresolved.


3. Cache Poisoning:

This attack is very common as it involves interference in the cache of the local DNS server. Attackers here try to replace an IP address with that of a miscreant address in order to gather information or to execute another attack.


4. Basic NXDOMAIN Attack:

Here attackers deluge the DNS server with non existing domain name in order to slow down the server. In addition to this, the cache in local server is also filled with NXDOMAIN results.


5. Phantom Domain Attack:

Server spends resources to satisfy the queries. These resources are used up uselessly by the attackers as they setup Phantom domains. Hence, it leads to failure of performance and slows down the servers as well.


6. Domain Lock-up Attack:

This is also intended to exhaust the resources of DNS. Junk or random packets are sent to engage the servers whenever it tries to resolve a request.


Protect Your Site from the Downtime Experienced By Many in 2016

2016 was a unique year that saw many sites going down for a variety of reasons, but most critical were the DDoS and botnet attacks. There is a way to make it harder for additional DNS information requests to bring your site down off the server. Make this the year that you get better protection.

Accidental Outages

Administrators that accidentally delete critical files accounted for a few major outages last year. One involved the National Australia Bank. Accidents can happen when there are a lot of files to keep track of. It took some serious backtracking to discover the problem, but it was easily resolved at that point.

DDoS Attacks

Cyber attacks are nothing new, but the year 2016 showed a record in the size of DDoS attacks experienced by websites. In some cases, it was showing more than double the amount of packets of information sent than had ever been seen previously. A few of the targeted sits were able to stay up and running, but a few went down for a period of time. It was a learning experience in getting and staying prepared at all times.

Botnet Mania

The Mirai botnet was very active in 2016 and is expected to be so again this year. It is able to force packet requests at a website in such bulk that there is little chance of escaping without adequate preparation. It is what was responsible for the nearly half-day outage of both Twitter and Netflix in 2016. Companies without a secondary provider fall offline easily being hit with a botnet attack.

Create an Absorbent Atmosphere

The more you cushion the ability of your site to take a DDoS attack, the less likely you will fall victim to one. You need to use things like cloud technology for information storage and utilize as much bandwidth as you can comfortably afford. These are easy ways to limit the destructive downtime experienced by companies last year. The use of firewalls is good for some threats, but it rarely helps in the situation of a serious DDoS attack. The site will fall offline before the packets ever reach the firewall.

Use More Than One Provider

Using more than one server provider is a way to operate more efficiently, fast and lessen the chances of a successful DDoS attack. There were companies last year that withstood the botnet attacks by simply having more than one provider. It might seem like an unnecessary added expense, but compare it to how much money you can lose by going down for hours at a time.

Contact DNS experts right away to get better protected from the threats of serious site downtime. If you are looking for more information, you may be interested in checking out www.bluecatnetworks.com.

Cyber Attacks and the Relevance of the DNS Firewall

Every system has a basic source of protection. For homes and offices, it is the security alarm system that keeps unwanted people out. For your computer, the DNS firewall is a protective fence that blocks the entry of malware. The firewall is so widely used that it is commonly found on the security checklists of many computer buyers. Learn more about DNS firewalls and where you need these devices the most.

The Regular Firewall is Not Enough

With so many identity thieves and hackers out there, your computer is not likely to survive without a firewall. Cyber criminals are working in groups and finding newer and better ways to divert the system. A regular firewall is no longer strong enough to secure an entire company. Some firewalls leave huge loopholes that are unprotected and undetected for years. Hackers take advantage of these areas by stealing information from the domain name system (DNS) in order to enter your network.

The Need for the DNS Firewall

A DNS firewall is also called the DNS resolver and it is designed to secure your Internet connections. The wall prevents you from entering malicious websites and sends messages to networks about security compromises. Securing your DNS gateway is necessary to prevent computer malfunctions, protect confidentiality and stop identity theft.

The DNS firewall is simple to use because there are no upgrades or installations required. Deploy your firewall in a few hours with the use of a few scripts. Not using a DNS resolver could cost you many hours of recovery for your data. Major search engines and corporations with unsecure resolvers have been attacked by malware agents. This happens when company employees open phishing emails, thinking they are trustworthy, and unwittingly release a virus. In many cases, the attacks are thwarted when people look into the log files and find out the malicious domain names. Finding out who the attackers is simple just like installing a protective firewall.

Hackers are taking advantage of the loopholes found in unsecure DNS infrastructures. They are forcing their ways into private networks and stealing personal information. Many of the top government agencies, search engines and Fortune 500 companies have become victims of these scams. For years to come, the number of threats will remain stable, even as security software becomes more advanced. Individual computer users should expect that they are likely to fall victim. All IT users should know that the DNS firewall is one of the most reliable lines of defense against the majority of attacks.

Why You Need More than DNS to Secure Your Network

In the past few decades, the IT industry has grappled with a wide variety of security issues that could potentially pose huge threats to their operations. One of the top issues that have raised a lot of concerns is DNS security. Taking into account that most of publicity around DNS is often made by vendors trying to market their solution, there has been a lot of misconception about the capability of DNS to secure networks and detect threat. However, the truth is, to secure your networks and detect potential threats, you need more than DNS.

DNS can easily be bypassed

Generally, you can only use DNS to detect threats to your system and protect your networks against applications and activities that use DNS. Immediately hackers realize that your DNS server is blocking or blacklisting their access efforts, they will have to figure out other ways out—the simplest being using IP addresses to connect to your network. When they manage, there is going to be lots of malicious activities on your network without you noticing.

However, this doesn’t mean that you shouldn’t focus on DNS security. Rather, you only need to remember that though utilizing a secure DNS is significant, you should strive to use proper technologies to monitor and block any malicious activity or traffic. All things considered, DNS is simply a partial solution to your network security issues because it can easily be bypassed by hackers.

The Way Forward

Security remains an integral component of a quality DNS environment. You can secure your network without having to spend much on the much hyped DNS security solutions.

1. Ensure that your DNS platform is widely distributed to lower redundancy. You can accomplish this inexpensively by virtualizing most of your DNS servers.

2. Ensure that you DNS servers are up to date by automating your updates.

3. Leverage on in-built security through secure configurations, hardening, and other security measures like Intrusion Prevention with rate-limiting and configurable firewalls among other measures. Monitoring the capability of your security measures is also a great move because they can go a long way in helping you detect any anomalies in your DNS query and response patterns.


There are hundreds of DNS deployments that have been in operation for long without suffering any DNS downtimes simply by implementing the above highlighted straightforward steps. When it comes to DNS security, you don’t need to worry about those accelerated hardware or costly threat streaming solutions. Just be smart when developing your architecture, ensuring that your DNS servers are well secured; never assume that DNS will offer your networks unified threat protection or management.

Protecting DNS Servers From Attacks

Cases of DNS attacks or hijacking are on the rise for the past few years. We still remember how Twitter suffered an attack in 2009 from Iranian Cyber criminals who took control of the company’s DNS records and rerouted traffic on their own servers. This means that every company cannot afford to ignore the importance of DNS protection. DNS attacks can be prevented if people have a clear understanding of the types of attacks and how to prevent them.

Types of DNS attacks

A compromised DNS protection server can attract hackers within minutes. An attacker who takes control of a compromised DNS can do anything with it including spreading propaganda and leaking crucial information. An attacker can decide to redirect all incoming traffic to his or her own server like in the case of Twitter hack in 2009. From his own server, the attacker can launch more attacks on the affected company. Attackers can also capture all incoming emails. This allows them to send emails using the company’s domain and benefit from the positive results associated with such emails.

Preventing DNS attacks

These types of attacks can affect a company’s reputation and source of income in a significant way. Hence, it is always a good idea to put up stringent measures to save DNS servers from compromise at any given time. DNS extensions such as DNSSEC can provide additional security to the servers, which were designed with little consideration for their security. Password policies can also keep hackers away from a company’s DNS servers. Stronger passwords and strict access instructions to the IT team are always good ways to prevent unauthorized people from accessing the network.

Companies are usually entitled to better service level agreements with every service provider or any other company they interact with on a service level. A company should ensure there are better SLAs from those who provide it with DNS services. The agreement should give clear guidelines on who to call in case of a problem and the contact details to use. The IT team must always monitor the SLAs and update them where necessary to ensure there are quality support mechanisms put in place. In addition, they must have a highly powered infrastructure to repel any attempted attack on the company’s network.

Also, there is need to configure the DNS within the company’s network. There are various techniques used to configure DNS servers, but the Master-Slave DNS configuration has proved to be the best. The master slave DNS server should have no access to the internet and must always be behind the firewall. It is possible to use more than one slave DNS server so that when one is hacked, the other can still receive updates from the master server. To achieve maximum security, constantly check the servers for anything fishy.

What Is DNS Hacking & How To Protect Your DNS Against It?

DNS Security

DNS stands for Domain Name System. Those who are new to the term, it is the system of naming the websites using legible words and language instead of using a set of digits, also known as the IP address of the website. The purpose of implementing DNS was to make Internet available for the masses. It is impossible to remember a combination of numbers for those who are trying to access any website on the Internet. Moreover, with the change in the IP technology, the set of numbers is changed with implementation of a new IP version. Domain names are the names in English or any other language that is given to a website. These names refer to the IP addresses which are saved in an online directory known as the Domain Name Server (DNS). DNS returns the IP address whenever a query for a website is made using the domain name. the IP address allows the computer to fetch the web page from a specific location where the web page has been saved.

Even though DNS is pretty much the backbone of the entire Internet communication network, the astounding fact is that it does not come with any special in-built security feature. The absence of security has long since made DNS the soft target for hackers. DNS hacking can be of various types. However, the basic aim of the hacker is the same I most cases, which is to make alteration to the DNS directory so as to serve their purpose.

DNS Cache Poisoning attack is one of the most malicious attacks which is carried out by any hacker. The aim of this attack is to replace the original IP address with another fake IP address which takes the user to a page of the hacker’s choice. The reason this attack is highly malicious is because it is the easiest way for any person to steal confidential data from any user who have visited the fake website considering it as the original one. The interface of the website is kept the same in order to avoid suspicion. DNS cache poisoning is often detected pretty late since there is no error message generated at the server end.

Another popular mode of DNS attack is the Denial of Service Attack. DoS means that the users of a particular website or any component using the Internet to communicate using the device or component is locked out of it. The infringer creates a loop of bogus queries which makes the server busy and unavailable to anyone who wishes to access it.

DNS Security

DNS security is of greatest importance. The first step is to ensure implementation of DNS firewall. This will boost up the DNS security to a large extent. Another option is to use cryptography to protect the data stored within the DNS server.

With the importance of Internet and information increasing by the day, it should be your top priority to make sure that the DNS of your business or service website is always protected. DNS security is an investment which is worth it.

Have You Secured Your DNS Server Yet?

If you are aware about network and security, you are probably well aware of what DNS is and how vulnerable the DNS server database is basically. However, if you are more into management and did not quite get yourself involved with the technicalities, here is a brief description of DNS and its security vulnerabilities that can lead to major loss for organization.

DNS or domain name system was adopted at the early stage of formation of the modern version of Internet to make it easy to access the various websites. Every website has an IP address which is a unique combination of numbers. However, expecting a person to remember unique combination of numbers for the innumerable websites the person will be visiting is simply illogical. Thus, each website is provided a name which can be remembered with ease. These names refer to the IP address and the DNS server directory keeps a reference of all of them. It is similar to having a telephone directory, only that this one contains IP addresses and names of websites.

At the time of creation DNS was not given an extra layer of security. Apparently no one considered anyone to target this part. However, this made the DNS servers soft target for cyber criminals. A little modification to the database can cause havoc. Also, traffic to and from DNS server can be modified and redirected to achieve ulterior motives. Since DNS structure is not modified at all, there is no way one can add any layer of security to it.

What are the types of DNS server exploits?
DNS falls prey to a variety of attacks. Here are some of the most popular ones.

– DNS Cache Poisoning – DNS poisoning is one of the most serious exploits to have happened in the history of DNS hacking. The target is the end users and hackers take advantage of the websites of financial services and banks to launch this attack. Basically a visitor is taken to a fake website that looks exactly like the original one when the person tries to access the original website. The attacker modifies the DNS server database to achieve this. Thus, the website name remains the same to the end user and it is almost impossible to identify the hack. Unsuspecting users enter their confidential information in the fake website which is then used by the hacker for malicious intent.

– Denial of Service (DoS) – DoS attacks cannot be termed as serious as the one above. It is basically disruptive and makes the website unavailable to the end users. This causes loss to the organization.
How to protect DNS?

Even though DNS is quite vulnerable, it can be protected using strong measures. DNS firewall should be implemented to block any unauthorized traffic or access. Also, using encryption and decryption methods to the incoming requests and their responses can prevent hackers from hijacking the traffic in any way. A good security measure does not take much investment, but can save millions.
