Is Your Dedicated Server Protected?

Dedicated servers are the powerful machines of web hosting services which is known for its performance and functioning to manage huge tasks. Owning a dedicated server could earn you a lot of benefits for a long-term. Though many dedicates owners forget one thing that with it’s care, it is also important to take concerns for its protection. It’s very important to take proper measures for security methods again malicious practices.

Well don’t worry, we got you covered as we are going to discuss some major threats to your dedicated server’s protection and how to prevent them.

Dedicated server basically is a hosting configuration within which an individual server is dedicated to one owner or for one purpose. To safeguard these dedicated servers, it is important to know what are the popular and likely threats to occur.

Dedicated Server

1st – Be aware of the default installations and remove the redundant services 

There can be instances where the default operating systems with configurations are installed. This could lead various un-required network services giving a chance for hackers to attack or hamper the server. You can prevent this by switching off all the non-essential services of your server and disable them. This will prevent the hackers to begin after the next reboot. This also contributes in enhancing your server’s performance

2nd – Allow minimum of remote access

Generally, it happens that the remote access becomes inauspicious. Tech people may suggest the administrators to log-in to net servers regionally. If there’s a chance where the remote access seems to be important, these tech people will make sure that the remote access is correctly protected. To prevent and discourage remote access you can use certain security tokens, various equipment’s and systems to protect your dedicated server. You can better enable a selected range of IP as well as accounts

3rd Don’t allow your production server to be used for production as well as testing at the same time

Once you allow public access for their applications and directories on your production server there can be instances where the net applications would result in being vulnerable as they won’t have any prior verification along with effective exception handling abilities. You should take proper care to this problem as if development and validation are carried onto a same dedicated server, it could lead several applications and other related files to be risked in danger.

4. Be sure about giving permissions and privileges

There can be severe damage to your files, resources and network if any anonymous visitor comes and gets the privilege to ask for the website’s information. These visitors could use these for malicious activities, putting your website in danger. Therefore, you should be careful regarding giving privileges and permissions to various visitors to keep your dedicated server safeguarded.

The above are the four major threat, where the dedicated servers itself could bend their knees down and get destroyed. Hence you should take proper care regarding your dedicated server as it is a valuable asset and the most effective one when it comes to web hosting.

Reasons to Make Your VPS Servers DDoS-Protected

Besides the problem for customers that are not able to access the website, there are many other damaging consequences. DDoS threats can culminate in lethal cyber crimes. Activities like virus activation, virus attacks, network breaches, thefts, etc can all occur because of these attacks. One of the biggest threats is clearly the huge income losses on account of these attacks.

When critical applications become unfeeling and the entire site slows down, the results can be terrible for any business.Another reason why VPS servers must be DDoS secluded is that of data breach threats. The DDoS attacks typically provide the perfect cover-up for many profitable crimes. So, using these disaster situations, hackers can get access to your network; they can even steal perceptive data.

Virtual Private Server

So, the security schedule undertaken by your host must be healthy and fault-proof. The provider needs to carry out usual data backups which should be spread across remote servers in dissimilar geographical locations.When there are frequent DDoS attacks on any website, the customers are likely to lose their trust and confidence.

Your website and network must be available and accessible at all times to preserve customer trust. When the existing clients are satisfied, they rate your site well and this attracts new clients. When a DDoS attack occurs, the primary target is the critical infrastructure. This automatically affects network performance and causes dissatisfaction amongst buyers. They tend to steer to other sites and this makes it very hard for the business to get new customers.

When there are normal DDoS attacks the business standing is affected. Brand image is the key to the achievement of all businesses and loss of client trust will smudge their trustworthiness in the market. Whenever the status of a business is threatened, rebuilding client trust takes a long time.

Backing Up Defenses against DDOS Attacks

Examples of legitimate tools used are helping, socket programming, and httping. There are also underground tools available for such attacks.

DDoS stands for Distributed Denial of Service. DDoS is a DOS attack where multiple compromised systems, often infected with a Trojan, target a single system causing a Denial of Service (DoS) attack. This kind of attack tries to make a computer resource unavailable to users.

DDOS attacks

Signs of a DDoS attack

• The US Computer Emergency Response Team defines symptoms of a DDoS attack as.

• Unusually slow network performance, either processes or opening files. Unavailability of a website.

• Inability to access a website. The dramatic increase in spam emails; this is an email bomb.

• DDoS attacks lead to issues with branches of a network being attacked. The attack overloads the network; other branches will try to compensate for the increase in traffic.

• This causes the whole network to slow down. A large enough attack can shut down entire regions of internet connectivity.

The DDoS attack may also use malware to cause further damage.

• Max out the processor’s usage so no work gets done

• Cause Microcode errors in the machine

• Lock up the computer by giving the processor erroneous sequencing

• Crashing the operating system itself.

Defending against DDoS attacks

• Recognize the signs of a DDoS attack. The first and best defence against a DDoS attack is recognising it early. Unfortunately, not all DDoS attacks are easy to distinguish from normal spikes in the network or web traffic or a sudden slowdown in network performance.

• DDoS attacks can take a website down quickly and emphatically. By knowing what you are facing, you can defend against them.

• DDoS Attacks range from brute force incursions to surgical strikes against key components of a network. The right tools to set up defences and a DDoS attack can be stopped cold.

Conclusion

Consider our advice to help prevent attackers from shutting down your network with unwanted traffic. Have an incident response plan in place and talk about DDoS countermeasures in advance with your ISP and a service provider specialising in mitigating these attacks.
